THE intense humidity of summer affects our daily life. Worse, the humid air even holds heat indoor, making us more uncomfortable and makes summer days even hotter.
Though modern roofing uses resin to repel heat and ultraviolet rays of sun, houses still using old type of roofing like galvanized iron can still resolve the heat penetrating indoor by applying reflective coating.
Reflective coatings can be applied through paints, membranes or textures that will reflect heat and ultraviolet rays of sun thus would help lower your electricity bill and gives cooler indoor temperature. Reflective coatings can reduce interior temperature by seven to 12 degrees, and the best part is that it can last for over a decade.
You can lower cooling costs and extend roof life by putting a light colored coating (also called cool-coating system) over an existing roof. Reflective roof coatings can provide a water tight surface as well as reflecting heat and reducing heat transfer to the inside of your house.
You do not need to demolish the whole roof structure, just simply convert the current roofing into a reflective one. You can either choose from any of these:
* Single ply roof. This type of roof can be reformulated or you can also use coat black membranes to create the reflective effect.
* Built-up roofs. The easiest way is to apply the cool coatings in top of the dark emulsion.
* Shingle roofs. Replace them with cool shingles or they can be coated at the factory.
* Tile roof. Tiles can be coated to reflect the sun rays.
* Metal roof. Paint these surfaces with cool coatings.
Among the benefits reflective roof coating is that it reduces interior temperature by up to 10 degrees, reduces roof surface temperature by 20 to 60 degrees, reduces energy consumption, and helps create a more comfortable interior environment.
