Flat roofing has always been a popular choice and alternative to sloped roofs. There are various advantages for flat roofs and as technology and installation have improved the benefits have grown greater. There was a time when flat roofs had problems with adequate drainage, however this is no longer true as materials and drainage methods have improved. On average flat exteriors are cheaper to install and maintain then their counter parts, and there are quite a few options for materials and installation methods.
The BUR system or Built Up Roof are the original and least expensive option for flat roofs. This system is applied by laying asphalt on the roof of the building. In most cases 3 or 4 layers are applied. In between each of these layers a fiberglass sheet is installed to increase insulation and protection from the elements. Additionally, a layer of gravel is usually applied to the surface to protect from the sun’s UV radiation. If cost is major concern this could be the best option.
Ethylene Propylene Diene Monomer is a rubber based roof that are resistant to many chemicals simple to apply. It is one of the most popular options for roofing because of its low cost and ease to apply, and the installation and upkeep don’t emit tars, or foul construction odors. Additionally, EPDM is known for its strength, so it is popular in areas with heavy wind and storms, and can last about 20 years. It has a flexibility that ideal for areas with fluctuating hot and chilly weather. This is typically the most expensive option, but also fire resistant and sturdy. However, with heat and time the rubber material can shrink from the perimeter of the roof.
Thermoplastic and PVC roofs are a layer that is applied to the top of the building. The technology came about in the 1990’s and has grown in popularity. It is relatively easy to install and can be done without heavy equipment. These materials have became the choice flat roofing in Brooklyn (our hometown) as well as many other densely populated areas throughout the world. The synthetic materials are fused together to provide a flexible but sturdy roofing option. They are known for excellent insulation, with added strength because the seams are welded together to prevent leakage. Heavy weights and sharp objects are able to puncture this material so care must be taken. These tend to be the most expensive option.
Depending on the usage, whether it is for residential or commercial, and the size of the roof each one can offer a distinct benefit. The middle option of EPDM offers a wide spectrum of installation options and prices to suit various customers.
