Roof replacement on flat roof is often a matter of practicality more than a matter of style. That is, commercial building owners' main concern when installing a roofing product, is choosing something that is going to be durable and no-nonsense. They don't care as much about having something that is particularly stylish. Flat roofs need to be more water resistant because they have to deal with standing water. Also, since they are often not visible from the ground, some building owners don't care at all what they look like. This article compares two of the best roofing materials for flat roofs.
Spray Foam Coating
Spray foam coatings are ideal for flat roofs. They are extremely affordable, durable, and reliable. Basically, they consist of a special rubberized foam that is completely waterproof when applied. The thin yet protective layer, is going to shield your roof deck from water. It will even add a valuable layer of insulation to your roof, slowing down heat transfer. Most spray foam roofs are just a solid color, like white. However, after they are applied, spray foam roof can be easily painted. Most just keep the white color because it is the most energy efficient in sunny climates.
Spray foam needs to be applied by experienced professionals. It is a unique application process, and one that not all roofing contractors know how to do. So, make sure you find a contractor that has experience applying spray foam.
Asphalt tiles are another popular choice for flat roofs. They are extremely affordable and easy to apply. In fact, some building owners will even do the work on their own. The tiles are waterproof, thin, and light weight. These are all essential features for a flat roof. Many asphalt tiles have adhesive backing so they can be applied to the roof just like a sticker. Asphalt tiles are usually more stylish than spray foam. So, they are a little more popular for building owners who have a roof that is partly or holy visible. Asphalt tiles are even used on residential properties, and they are well liked because they are so durable and easy to maintain.
In the end, it is easy to see why both asphalt tiles and spray foam are popular roofing solutions for commercial buildings. Most building owners make their decisions based on the cost. In general, foam roofs are going to be slightly cheaper. For more information, contact companies like Moriarty Roofing & Sheet Metal.Share
