Types of Flat Roof Construction
You want flat roof construction and you want to get the right CAD drafting job to get the details right. You’ll do this as an earth-conscious individual who takes part in reducing carbon footprint and avert global warming. Your decision includes a solar panel on your roof which will make the most of solar energy for electrical and energy purposes.
All these are possible if you have a flat roof. There are advantages in having a flat roof and some were mentioned earlier. There are several techniques to choose from and the following three are on top of the list as these are popular among various people across the globe:
The first is called membrane roofing which spells durability and water resistance. This membrane roof is set up by utilizing several PVC sheets. The specification of each sheet varies in thickness, from 30mm to 60mm. There is no need for a moisture resistant barrier if you choose to put up membrane roofing.
Your second choice is built up roofing. Among the three, this is the oldest technique. This also happens to be the favorite in the USA. Moisture barriers need to be put up beforehand. On top of the moisture barrier are alternate layers of waterproofing materials and bitumen. The number of these layers will identify the superiority of the roofing.
Spray foam roofs is the third one and this makes use of polyurethane foam. The foam can give a protective covering for the roof. Sturdy sheets of foam insulation are attached to the roof followed by spraying a foam solution to the roof. The thickness of the foam is different across the roof’s surface to aid in the proper drainage. Lastly, an elastomeric coating on the roof will aid in keeping the roof in place, preventing fire and providing water resistance.
