Easy Solutions for the Common Leaking Roof
It has unfortunately come to be accepted as common place that roofs in Thailand can tend to leak. Even luxurious homes worth over 25 million Baht can’t seem to escape this issue which stems from a common problem shared by all homes in Thailand. Steel structures are used as the framework for all roof construction. This combined with the extreme sunshine that we face in the tropics causes these steel structures to expand and contract which, over time, will start to dislodge the roof tiles, leaving minute openings between them. They do have a failsafe system, which is the use of thin metallic sheets under the tiles to provide in a sense a double layer, but is also ineffective in the long run. SprayMe Roof Insulation, a relatively new company founded originally in the Hua Hin- Cha’am region, has come up with an interesting and durable solution for these troublesome woes. They have acquired machinery that applies chemicals which when mixed, creates a rigid layer of foam, which is sprayed underneath the roof tiles. This foam, also known as Poly-urethane or ‘PUR’ foam, consists of two completely benign chemicals
that when mixed, form a quick drying layer of foam with a hard but flexible skin. The foam is applied via a high pressure spray gun, and when it dries forms a layer about 1.5 inches thick and thereby creates an impermeable barrier against water, moisture, insects, heat and noise. At prices ranging from just 450 up to 550 Baht per sqm. of roof area, this works out to be quite an effective, convenient and yet inexpensive solution as the roof treatment is guaranteed water proof for ten years.
The roof tiles are also glued not only to the structure but also to each other, thereby ensuring that even in high wind situations, none will get loose nor dislodged. A more remarkable side effect, which is most convenient,
is that once treated with the PUR foam, the roof as a result becomes much better insulated against the heat
of the tropical sun as well. In fact under testing, temperatures under the roof were shown to be reduced by a whopping 7 degrees Celsius after treatment and made the rooms of the homes much cooler. Depending of course on the type of construction, room temperatures inside the house usually drop between 3 and 4 degrees Celsius after treatment of the roof with spray foam. If your house has double walls instead of single brick walls, or PVC window- and door frames instead of wooden frames, savings on your electric bills are even higher. On average, the cost of roof treatment is earned back in 7 to 10 years via lower
electric bills throughout the whole year. SprayMe Roof Insulation uses chemicals provided by Dow Chemical (U.S.A.) and BASF (Germany), thus ensuring the highest quality standards possible. Combined with the newest technology from the USA in our spray machine, the Reactor A-20 from Graco, an air driven, easy to use and lightweight unit that uses two pumps, one for each chemical, connected to the spray gun by a 90meter long hose. This way, even roofs of high-rise condominiums or industrial complexes can be treated with PUR foam by us without having to move any machinery out of the truck and into the building. Currently five projects in the Hua Hin-Cha’ am region and many, many more in the Pattaya region have introduced the spray foam treatment as a standard upgrade to their new builds since SprayMe started promoting its product. It is therefore not hard to foresee that within 5 years, all projects aimed at the foreign market in Thailand will utilize this amazing, unique and cost effective method to guarantee sealed roofs that do not leak and the added bonus of long lasting
insulation against the blistering heat of the t ropics. If you’re considering having your roof done, contact us by e-mail or phone and we’ll make an appointment for you with one of our specialists who will make you a quotation
