According to the National Roofing Contractors Association (NRCA), roof systems and materials generally are divided into generic classifications: low slope and steep slope.
There are roofing options for you no matter what type of roofing structure you have, so it is important to be informed about the best type of roofing material to use on your home. Start by determining the pitch of your roof, something a certified roofing estimator will do right away. The pitch of your roof is defined by the rise over run factor. This is the number of feet your roof increases in elevation per 12 feet. For example, a 2:12 pitch means your roof changes elevation by 2 feet for every 12 feet of roofing.
Low slope is classified as a roofing membrane with a slope less than or equal to 3:12. This category also includes flat roofing systems, which have little to no pitch. These are most identified as roofs that are nearly horizontal, however, have enough slope so that the water can drain off (typically 1:12 pitch or lower).
Here are some ideal roofing materials for low-slope roofs, in order of affordability. Built-up roofing is the traditional hot tar and gravel roofing system. Modified Bitumen, also known as Brai, is comprised of rubber and elastomers, which also are arguably stronger than tar. There also is TPO, which is a single-ply rolled roofing system; the product consists of large sheets of plastic or rubber compounds that are mechanically fastened or fully adhered to the roofing deck. The seams of the TPO product overlap and are then welded together by heat, forming a monolithic, or seamless, roof. This is the new roof of choice for contractors, and it offers a great warranty and excellent reflectivity. Another viable option to utilize for low-slope roofing is specific types of mechanically fastened metal roofing systems. These can be installed on slopes as low as 1:12.
Surface Shield Roofing Co. prides itself on being a certified installer for numerous material manufacturers. Being a certified installer allows the company to offer valuable warranty options to homeowners with low-slope roofing systems. These warranties range from 10 to 25 years, depending on material choice and installation.
If you already have a low-slope system in place, but want to cool down the area or enhance the longevity of the roof, the company recommends utilizing any choice of its silicone or elastomeric coating systems. These will create a watertight roofing membrane as well as assist homeowners that have ponding water issues that may be degrading the integrity of their current roofing system. Surface Shield Roofing Co. is a Platinum Certified Installer for Tropical Silicone and a certified installer for Gaco. This allows the company to provide ironclad warranties on coating systems, ranging from 15 years to a lifetime.
The NRC A defines steep-slope roofing as roofing structures that exceed 3:12. Five of the most popular roofing systems that can be installed on steep-sloped roofing structures are asphalt shingles, clay or concrete tile, or metal and wood shake.
Each of these roofing systems are equipped with material warranties ranging from 20 years to limited lifetime coverage. Surface Shield Roofing Co. also takes pride in offering the CertainTeed Select
ShingleMaster program, and therefore is able to provide homeowners with quality asphalt shingle installation that can provide three- to five-star warranties. These additional warranty options allow homeowners to enjoy their new asphalt shingle roofing system without future out-of-pocket expenses.
