Two New Roofing Options for Costa Rica & How They Address the Challenges of Tropical Roofing

In this article we are going to investigate and analyze the benefits versus costs of two excellent new roofing options versus other more common products typically used in the Costarican roofing market.

Today’s information is all about roofing options. Needless to say this is a critical issue in the tropics especially in the Central to Southern Pacific Region that get from 10 to 17 feet or  3 to 4.5 meters of rain a year.  Not exactly the ideal location to have a poorly performing roof!


My general dislike for anything in the way of metal roofing has not abated at all fueled by other far superior options that have also come available as of late that demonstrate clearly that there is far better options that a wise consumer can elect.  As you will note on the latest post  on  the Playa Grande build we are using a 3 ply UPVC ribbed roofing where we just put up the first section of roofing over the storage shed.  Verrry pleased with the results as we see the rubber meet the pavement on the job site.  Before we get into specifics of benefits, typical problems and maintenance of various roofings lets take a look at the costs of installing and maintaining the various types.

Cost per M2 to install roofing then to maintain over 20 years

Roofing Type Cost m2     at install Maintenance m2 over 20 yrs Total 20 yr cost Cost per M2  Year Avg.
Ribbed Metal $13.50 $8 $21.50 $1.08
Imitation tile in metal $20.00 $8 $28.00 $1.40
UPVC $19.75 0 $19.75 $.99
Asphalt Shingle $40 $30 $70 $3.50
Polysand Tile $47 0 $47 $2.35****
Clay Tile $80 $40 $120 $6.00

Note: *** 30 years of life expectancy remains while others had to start all over again

Option #1 

Ribbed UPVC – Smart Roofing

Best roofing for the BUCK $$$$  


The benefits this option offers:


  • Coolest of all sheet roofing
  • Quieter than any other sheet roofing
  • Roofing itself has insulation value lower cooling costs
  • Tougher than any metal or painted product
  • Solid color going through the whole skin limits fading & scratches
  • Won’t rust or corrode in any way
  • Light weight
  • Larger sheets with fewer joints than any sheet roofing product
  • Won’t buckle or be damaged by any worker on your roof
  • Won’t grow molds and likens
  • 15 year warrantee
  • ECONOMICALLY PRICED with lowest 20 year cost


This product is imported from Japan and has been in use here for six years with a a lot of traction especially in commercial and industrial roofs in the Central Valley. Eg. Price Smart.  Please do take note of that, as companies that have hundreds if not thousands of square meters of roof to look after are looking at the long term costs to maintain their buildings not just a cheap upfront cost factor.  It is only stocked in white but red and green can be ordered with the usual 60 to 90 day lead time which is no problem to incorporate into a building schedule.  For all intensive purposes especially in the Guanacaste, the white is by far the most functional being of course the coolest option.


Ian and Corynne felt it fit in with their style well and it was a far more intelligent choice than their neighbours who chose to paint a cheap undulating tin roof (that will peel like a snake in a few years) a dark chocolate brown color.  At my politest I would call this a silly choice especially under the long summer sun days of the Guanacaste!  Also the long term maintenance realities are drastically different between these two options.  Reality is the bloom will long come off the rose from when you first see that new roof on your dream home versus when you are back repairing it on a regular basis.  Meanwhile getting reminded as you pay that never ending bill that these types of tin roofs are not actually economical and most certainly provide exactly zero in the way benefits what so ever.  In fact of the above list the only thing I can say about tin is it is light weight.  Other than that is scores a big F in all aspects of desirable benefits one would be looking for in a high performing roof cladding.

Lets also not forget the long term affect of putting a tin roof in a salt zone.  Just 2 kms away from their home and the neighbors tin roofs I noticed the rather predictable affects of salt and tin playing so nice together.  I took this picture while having lunch at a hotel right in front of the surf that provides such a nice daily salt bath.  This pictures tells the whole story  of what will befall on any owner making this rather foolish decision in but a second!!!

Holly metal roof


There is no such thing as a cheap roof in a tropical climate as every time I have inspected a failing roof, often on expensive homes, that roof has turned out to never be economical.  This really demonstrates the difference of cheap versus economical! When you are ripping junk off and starting all over again in a short period THE REAL COST NEVER ends up being cheap.   My best example that broke all records from my personal experiences occurred in Bello Horizonte, Escazu where a six year old Zinc Teja roof had left behind it destruction of ceilings, walls and eaves adding up to $7,000 in additional damages.  The actual cost of this roof for only 6 years of service ran the client right around $60 m2 or $10m2 per year almost double of clay tile even, hence no matter what one chooses to call that , cheap is definitely not a likely choice description.


This UPVC is constructed as a 3 ply sheet with a  thick polymer carbon fiber core sandwiched between two layers of solid UPVC skins as a result of this construction it does insulate pretty well.  That is the first test I did with my first sample, I laid it out in the noon day sun and found that after an hour it was just barely a tepid warm versus any tin roof that would have been more like picking up a frying pan off the stove in that same time.  At the beach I still would boost this up with the use a reflective foil insulation under it for both the extra heat as well as additional sound insulation. This costs another $3.50 m2 so our typica roof runs from $350 to $1,000 extra to insulate which is a downright bargain for the benefits it brings in creating as high quality of living environment as possible.  The combo of the two creates a very quiet roof considering nothing can be worse than tin under a driving Tico rainstorm.  Any who have spent any amount of time in Costa Rica have experienced just how deafening such roofs are when you can barely carry on a conversation and forget listening to anything like a TV, computer or phone.  Even a garage band would be better as they will grow out of it but I somehow think heavy Tico rain is not exactly a passing fad.


Let’s look at cost factors, the cheapest tin roof runs $13.50 m2 versus Zinc Teja (the red fake, verrrry bad imitation of tile) is $20 m2 versus this UPVC is $19.75 m2.  In the Playa Grande case it was about a $1,000 bump up from the cheapest ribbed tin.  This is what I would call spending REALLY smart money.  Oh lets not forget it will not rust or peel or fade out in white especially.  Within 5 years all the tin fades out a good 60% in color intensity so if any piece gets damaged, which is mighty easy, any patching or replacement of pieces is glaringly obvious bringing about a serious cosmetic deficiency of your home.


I shall detour us a bit at this point from the UPVC roofing into a more general  discussion of design and maintenance issues prior to selection of any type of roofing.  As a perfect example for comparison I inspected a drop dead gorgeous Bali style home in the mountains of Atenas.  Although the rest of the home was impressive the builder conned or at least deluded the owner and stuck this crap Zinc Teja on a  very steep pitched roof (12/12) that was perched on the side of a cliff.  Predictably within 10 years the paint  had gone to crap so the owners hired an acrobatic painting team to come in to paint such.  Sad to say what they did not know is that even though the first finish on the roof only lasted ten years the rest of the story is going to be even uglier as the on site applied paint will never do even that.  Site applied paint and baked on in a factory finish are drastically different beasts by a long shot.  Hence they will be hiring this same crew of acrobats again in five years at best.

This brings about two other points of consideration in any discussions about roofing options.  The value of the home must be reflected in the quality of the roofing as well as access to the roof for future maintenance will drastically affect the costs of such.  The first foolish thing in this case was this is a Mercedes home with  a beer can roof on it.  That is one really stupid idea especially when the roof in this type of design is a major focal point to the home hence has a huge affect on curb appeal and future resale value.  Then we must add to that, a roof that is extremely difficult to access will double to triple the long term maintenance costs hence when you go for such a design along with difficult location the maintenance costs have to be a serious consideration in the election of what roofing should be used in the first place.  As a contrary example we are just in the final stages of design of a very similar style of roof for one of our next homes and this crap tin roof was NEVER EVEN REMOTELY CONSIDERED!  Stay tuned you shall see what I mean later this year.


Now back to UPVC as we have seen from this first sample it supports weight very well and does not buckle under your weight if one follows the recommended nailer spacings of 70 cm or 27″ max but even better at 24″ as we shall do on the house.  It is an inevitability that there is going to be someone up on your roof sooner or later who does not give a shit and will step between purlins making any tin roof cave in which is when you typically get lakes forming in a roof that eventually will look like a war zone.  We also found the overlapping ribs close nice and tight so as to avoid leaking caused by wind driven rain getting between sheets.  The typical tins are not any where equal to this due to the rigidity factor hence the screws carry the compression far better from between screws.  This rigidity comes about as ss you can see from the below picture the UPVC is a good six times thicker than any of the tin products hence its rigidity factor and weight carrying capacity is much higher.  Also this comes in huge sheets 1.25 m or 50 inches wide and lengths up to 40 feet long hence fewer joints to contend with in the first place.

This product comes with a 15 year guarantee but I believe it will far outlast that and will definitely outlast tin 2 to 1 if you are within 50 miles of the coast.  While discussing the benefit of salt resistance lets divert to one really goofy comparison.  Often high end beach homes are built literally at the surf where the luxury standard is to build two roofs by putting a tin roof under traditional clay tiles.  That is utter insanity, here is why that is!  Even though the tin is added because clay notoriously leaks hence this protective layer is added to catch drips however this protection is quite short lived.  what is going to happen is the onshore winds are going to blow pounds of air-born salt mixed in with surf mist each year in under these tiles which will then land on that tin and eat your supposedly protective under layer of tin within 10 years or if you are dam lucky 15 years.  Being galvanized only slows down the natural process it most certainly does not stop salt corrosion or rusting.  Hence you end up with a luxurious??? and expensive at $80+ m2 roof that will have to be ripped off and re-tinned every decade or so to stop the leaking through the rusted out tin.  Each time you do this at best  you will salvage 90% of the clay tile but get to pay for labour to remove, dispose of, then add new tin and labour to haul it all back up there.  So the victims to this stylish insanity will start out with the most expensive of all options and then get the privilege to reinvest 50% of that same cost every 10 – 15 years.


Now to put stupid on steroids if you experience an earthquake, as Guanacaste did in 2012, all that tile is going to end up in rubble at the drip line of your roof.  I further question this idea of luxury with the fact that in most locals this tile turns black within two years as the mold (hongos) take over.  Our own house here in Escazu is totally blacked out except under eave areas which IMHO is nothing but UGLY and dirty looking. Without question the absolute worst roofing option of all promoted by architects, builders and designers that are brain dead.  A roofing product designed CENTURIES ago has no place in modern construction, PERIOD!


While on the subject I would be remiss not to also do a comparison to asphalt shingles which are quite expensive here at over $40+ m2 yet by their tenth birthday they look like they have been through a blast furnace.  These are relatively heavy which obviously affects shipping costs as well as the dead weight on your roof structure.  However even without the tropical sun to fry asphalt lets also look at  the avalanche of warranty claims going on in the USA right now.  Various manufacturers like IKO have not even come close to meeting their warrantees.  The warrantee periods have been extended over the past 30 years while the actual quality of the input products have gone down.  Not exactly a sustainable formula leaving predictable results like 40 year shingles that are toast in 12 – 15 years in northern climes hence you can only expect worse results here.  So after a decade you get to peel them off and start again and here there are no recycling facilities of any kind to deal with the tons of debris that must come off your roof.  Definitely not a green roofing product.  My logic is why pay shipping costs and taxes on a product every decade versus doing so once in a lifetime for a lighter not to mention more elegant looking product.  Other than that take a look at this photo of these 10-11 year old shingles on the grand entrance into a project that is just 1 km from our home in Escazu so elevation of 3,800 ft.  I shudder to think as to how they would perform at or near to the beach level.  This roof is leaking as evidenced by stains in the eaves but because it is over the gate and guards office it is not viewed as important to the administrators. But what  if you were getting doused in your living room?  Considering this is the second most expensive roof type this is not what I would call a brilliant option in roof cladding.  As they say a picture is worth a thousand words so I will shut up.Fried Shingles


I trust you can see why I am a big fan of plastics/composites in general especially recycled ones versus these older and what I would call outmoded versions of roofing.  For the dollar spent and performance asphalt is in my opinion one of the worst possible choices one could make with clay tile only being worse.  I am not alone in my opinion as two other builders whose blogs I also follow write with the same views on this.  If you care to check in with them be my guest, Tim Carter  is at this very moment installing Davinci composite slate tiles on his own roof after his IKO shingles went to crap in 12 years. .

Also Steve Maxwell  I have followed both of these blogs for the past 5 years or so and in fact Steve is the one who got me going on the SIPs as well as the first I heard about PEX from.


There is another roofing I have seen in one project this is imported from New Zealand.  I only even mention this one for amusement sake as I find it downright goofy plus expensive.  It is an aluminum base sheet rolled in another bad attempt to mimic clay tiles then a sand grit is glued down to it.  This is also over $40 m2 and is without a doubt the worst possible idea for cosmetic durability.  With it being aluminum anyone walking on it would be like dancing on eggshells and what if a mango or fruit of any kind falls on your roof (what a strange concept in paradise), monkeys or the worst of all possibilities big monkeys from cable or ICE up there stomping around on your delicate and expensive and shall I say really stupid idea!  Again there is absolutely nothing green about aluminum either and the question remains as to how oxidation in coastal/salt areas will affect such a product over its life.  Being aluminum yes it will last longer than steel but its fake look along with cost and cosmetic fragility leave me shaking my head in be wonderment.


Option #2

Polysand Tiles – Canadian Made 

High End Recycled Plastic & Sand

Roman and Slate Style Tiles


I was approached by this company from Canada after viewing one of my videos on recycled plastic tile roofing advising me they had a superior product compared to the  ones made in Costa Rica, that we have used in the past.  This is the result of that investigation and comparison of products.  Lets first take a look as to how this impressive product dresses up a home.

Polysand 1

Polysand 4

Roman tile in red

I have made a video regarding our testing of the samples they sent me and I must say they are making an impressive product however this product is for those who want their roof to be a show piece not just simply utilitarian.  At this point the cost would be more than double of the UPVC roofing at $47.15 m2 at least as long as it remains an imported product.  If there is sufficient interest in the market here they would like to start producing this product right here.  This would eliminate the import taxes and shipping costs which is no small matter at a third of the final cost.  Last I checked the principle raw ingredients of plastic and sand are indeed not too hard to locate in Costa Rica.  This is indeed a green product considering its ingredients yet within the price range of all of its competitors combined with high end curb appeal styling.


Benefits this option offers are:


  • 2nd Coolest roof available next to white UPVC
  • Incredibly Quiet due to its density that stops rain vibrations
  • Toughest product I have ever seen or tested – ICE workers can dance on your roof
  • Won’t corrode
  • Medium weight due to its thickness and sand content
  • Will not fade out or scratch as do painted finishes as color is in the material
  • Rigid requiring fewer hidden fasteners – none in the wet zone
  • Small pieces that won’t peel in high winds
  • Fire resistant (see video)
  • Luxury appearance without a luxury price tag at $2.35 m2 per year over 20 yrs
  • Most cannot tell the difference from tradtional roofs at double to triple  the cost
  • Will not turn black from molds and liken as do clay or cement tiles
  • Zero maintenance
  • Green product using totally recycled plastic
  • Longest warranty offered for any roofing product

These come with a 50 year warranty as well as offering both the roman style of tile as well as the European slate style of roof.  We all know the life cycle of plastic is very long when dumped in a landfill but in this application the long life is exactly what we want in any roofing product especially when combined with sand as the base.  Without question these do make for a very classy roof at a reasonable price as compared to other options.  I have as yet to see any product in any of the price ranges that actually do any where near as good of a job at mimicking the traditional tiles plus doing so in a green method.  Still massively superior to any clay tile in that they would be less than 1/3 the cost yet will not leak like a sieve, grow plants, break, require maintenance or require massive structural enhancements.  The traditional clay tiles weight tons more dry but get even  worse yet when they retain water during our rainy season.  This makes their excessive weight balloon up even more tons hence requiring significantly beefed up roof structures that of course add to the cost.

The Polysand tiles are heavier than the thin solid plastic ones we have used due to 60% of the content being sand plus the fact that they are double the thickness hence are way more rigid while still being relatively light weight at a third of any clay/cement product.  One big thing is they are very rigid yet far from brittle hence fastening them down only at the top edge allows them to function without any problems with lifting in wind versus all the light weight plastic only tiles which certainly fail on that test.  In fact all these thin ones require screws be used at the bottom of each tile which creates a blemish in the face of the tile as well as a perforation that most certainly will never help.  The Teja Real tile made here I would not use at all as it is especially bad for this as those screws create a perforation right through into the lower tile so when a screw comes loose or falls out (which some will over time) there is an open hole left behind to leak of course.  Due to being smaller pieces these will not peel in high winds such as metal is famous for doing in areas like Lake Arenal.  There is saw a standing seam tin roof just south of Tronadora where they had had to come back twice and add more fasteners to stop it from flying like a kite.

For the rest of this story go to this video link where you will see us doing our sledge hammer test.


Here is a fire test comparing to composites side by side.  Fire is not a big deal in most situations in Costa Rica but still nice to know it has good resistence.
The Polysand home site is here for those of you with more enquiring minds.
I am adding another subject in here that is highly related to roofs hence I am tagging it in here while you are thinking about roofs.  It has to do with those gutters and how to keep them clean.  This also more than slightly relates to those that want to be doing rainwater harvesting as you certainly don’t want tons of organic crap ending up in your water storage to decompose.  Needless to say Costa Rica has great capacity in burying you in leaves.  Secondarily you may well have more enjoyable things to do that to regularly get up on your roof to clean all this junk out.  However the really big issue is as far as this thought process goes is what is your situation 20 years from now.  When you retire you are most likely quite capable of cleaning your gutters but down the road can or should you be up there in your advanced years.  It reminds me of a story from my best Tico friend Giancarlo who told me about his dad who was up there doing exactly that in Escazu after his odometer had clicked over 80 years.  He does a cartwheel off the roof ending up on his head.  The good news was that after an ambulance ride to a social hospital who checked him out first and his wallet a distant second they found no severe damage.  Of course his kids wanted to kick the old fools ass for being up there in the first place.  Yes it is good news to be capable of such a task at 80 but just the same a job possibly better left for the younger and more agile.
Hence the end of this story is I am bring in some stainless steel gutter guards that will filter out all the crap and let the water into your gutters.  I have never seen anything in Costa Rica to do this and just a simple screen DOES NOT WORK whereas these patented ones do.  They are going to run about $5 a foot I estimate but a small price to pay for something that A) works and B) lets you amuse yourself with better things and C) keeps you the hell out of the hospital or better yet the morgue!
Any comments or questions are most welcome as I would love to hear what you think of these options as compared to what is typically offered.

Two New Roofing Options for Costa Rica & How They Address the Challenges of Tropical Roofing — 7 Comments

  1. I was ordered asphalt shingles from China, but there is not enough, where can I buy it in Costa Rica?
    Please contact me on 50684238725
    My name is Elram,
    Or by email;
    Thank you for your attention.

    • Well lots of luck to you as shingles don’t do well here in the tropics as I have observed you can’t expect to get much more than 10 years out of them let alone chinese ones. You are much braver than I to tread into those waters. These also end up being very expensive due to shipping costs and then the sheeting to put under them is much more costly than in Canada or USA. Then once their life is over there is no way to recycle them either. Then you get to do this all over again a mere 10 years later. At any rate way to late for that advice to be of much use. Meanwhile at any rate most good ferraterias will get them for you. Macopa on Calle Blanco in San Jose is one of the largest importers of this bad idea. EPA and Construplaza have them as well but this all depends on where you are needing the product as to where best to get them if you are out at the beaches or rural area then find a larger ferreteria and they will bring in for you from San Jose.

      Hope that helps you.


      • Further to this thread done several months ago we have our first now 100% recycled tiles (plastic mixed with crushed glass) on the way to Costa Rica for three homes and at a price very close to the shingles that Elram was asking about just one slight difference one product is lucky to survive ten years and the other has a 50 year life and pretty much indestructible. I tested the Polysand with a sledge hammer how do you thing a shingle roof would do under that test??? I had made comments about what a bad idea shingles were based partly on a project just 1 km from my doorstep in Escazu which is nothing when compared to the severe abuse such would encounter at beach temperatures. Well just a couple months back off came the curled up ten year old shingles from the grand entry to this project and new ones went up, talk about incredible stupidity. The three pigs were brighter, they at least did not keep repeating the same stupid mistakes. Economically this is nuts since one gets to pay the shipping and taxes on this horrible product every ten years but on a green basis it gets far worse. There is so few shingles in CR that no one could possibly recycle them plus recycle them into what? When compared to USA and Canada where they are everywhere at a fraction of the cost and most are now recycled so at least somewhat greener but I still choke up trying to say green and asphalt in the same sentence. Kind of right up there with pregnant virgins. 🙂


    • It is readily available in the Central Valley where most of its use has been in the Commercial / Industrial sectors like Price Smart.
      Typically not readily available out at the beach and most ferraterias know nothing about it. I do sell it to clients who come looking for it or use it in our projects such as the Playa Grande build. I do not sell anything I have not personally built with myself and as a result of that three of our tests failed on the first edition hence have not and will not be repeated. This roofing has a 15 year warranty but unlike the current disaster in the USA shingle market it has already exceeded the warranty period. However since the Polysand recycled roofing came onto the scene most of our clients have been going in that direction. Over 75% of those in process want a more stylish and greener roofing option with the 50 year guarantee to it that is pretty much indestructible and leak proof with better color selections. THe UPVC is only stocked in white with red and green available with a 90-120 day advance booking. Right now there is 56,000 lbs or 25 tones of Polysand and reflective foil insulation bouncing around out on the Atlantic on its way to supply three roofs, my Casa Perezoso build plus two Guanacaste builds at Pelada and Junquillal.




  2. Would like to know when this article was written. I am going to change the roof on a building located in Puntarenas/ocean side, and I would like to know if anyone knows how to get the metal roofing used in the states.

    • Amy thanks for your inquiry.

      I tried to reply to you directly as well but possibly you entered the wrong email as yahoo keeps bouncing it back as invalid address.
      So hopefully you will come back to review my reply to you since I can’t email you and all my pigeons died.

      Several problems in answering this. Steel roofing is verry vague as there is huge differences as to what you could be comparing too.

      HOWEVER I do not EVER recommend steel in the tropics!

      Here’s why…

      1. You are in an intense salt environment combined with massive UV intensity hence the paint surface at best lasts only 10 years after which needs recoating every 5 years then at about 20 years it is gone from oxidation.

      2. It is hot as hell 365 days a year. Think of it this way, what you make a frying pan out of does not make an ideal material for any tropical roof especially one that oxidizes.

      3. Noise, noise and more noise. Metal is brutal in creating that deafening drumming effect when our rain pounds down on you and you can’t carry on a conversation, talk on a phone or listen to any kind of entertainment. Considering this time makes up almost 60% of the year it to is a huge benefit to avoid this problem by careful selection of suitable roofing material in the first place hence why I never use metal roofs.

      Also I get calls all the time with people complaining about their leaking metal roofs and in the past I have completely replaced roofs as young as 5 years due to both bad design (the crap that they bend in an attempt to look like tiles, zinc teja) as well as horrible roofing installation. One would be most mistaken to assume that those who grew up in the tropics would respect just how much and hard it can rain here!

      I have only found two roofings that I like and that make tight roofs that eliminate these fundamental faults of metal.

      1. UPVC ribbed roofing made in Japan but is quite common here especially on commercial roofs in the Valley, like Price Smart. It costs the same at the 20 year mark as metal because it requires zero maintenance since it does not oxidize. Cuts noise by over 70%. 15 year warranty but has been in use here about 17 years now. It is only stocked in white but red and green can be booked 90 days out.

      2. About 80% of our current clients are choosing a high end 100% recycled roofing from Canada. Currently I have 55,000 lbs of it bobbing around someplace in the Atlantic. This is a very stylish roof and does indeed imitate a mediterranean clay tile or slate style of roof. It is a thick roofing hence eliminates the drumming effect. Has a 50 year warranty. It is near to indestructible as we went at it with a sledge hammer over a concrete floor. This is however a much more costly roof yet considerably cheaper than clay tile without the weight and leaking problems. That is why I have found most of our clients want a more stylish as well as tough roof that wont leak and is totally green.

      No matter what roofing you use though spend the extra and insulate under your roofing with a reflective foil insulation (also in same container) as this great product bounces out 96% of all radiant heat so it will make a HUGE difference in the comfort level and expenses in running you home. Massive difference in A/C space or avoiding it in the first place when you stop daytime heat gains!

      Hope that helps in your quest for better solutions.
