As a commercial property owner you may have to find an alternative roof option at some point during the lifespan of your building. Commercial roofing designs for flat and low sloping roofs usually come in 5 different classifications. These five classifications are: metal roofing, built up roofing, modified bitumen roofing, Spray Polyurethane Foam (SPF roofing) and Ethylene Propylene Diene Terpolymer (EPDM). When you find the right roofing contractor you can then discuss the options you have for your commercial property. When talking with your contractor about your options there are three essential aspects that you want to think about when it comes to a low sloping roof. These are the weatherproofing against the elements, reinforcing for wear and tear and surfacing that protects the inner layers against elements outdoors as well as US rays thrown off by the sun.
When considering roofs one of the preferred choices for material especially for commercial buildings are metal. This is because metal roofs have a great records for being durable, fire resistant, sustainable and energy efficient not to mention strong. These roofing materials are made by fastening corrugated metal on existing structures. In terms of the best and most common metals used for metal roofs you can use lead, tin, stone-coated steel, copper, stainless steel, aluminum, metal tile sheets, zinc and aluminum, silicon coated steel, and corrugated galvanized steel. They also come in a great range of colors and coatings that offer rust resistance, waterproofing and reflect the sun ray’s away from your property which helps to curb energy costs from HVAC.
Built Up Roofing
This type of roofing is generally known as the “tar and gravel” roofing. Built up roofs are made of plies of mats as well as fabrics and felts that as fastened together using asphalt, coal tar pitch or bitumen. When being made these layers as usually alternated in layers of plies and bitumen. The final layer of the roof is a weather resistant coating, mineral cap sheet, aggregate mix, hot asphalt and gravel. Built up roofs are great at being very resistant to punturing and weathering. This in turn helps to reduce the need for premature roof repair.
Modified Bitumen Roofing
A modified bitumen roof is made of reinforced roofing fabrics that have bitumen in between the plies. They’re similar to the built up roofs and are installed as a two-ply system that’s laminated on the roofing surface. These roofs are highly resistant to puncturing, tearing and foot traffic (from workers) and it’s all because of the use of Styrene Butadiene Styrene (SBS) as well as Atactic Polypropylene Polymer (APP) polymers. The SBS is used to enhance the roof’s resistance to low temperatures and the brittleness that can occur. APP works to up the tensile strength and fight against foot traffic damage.
Spray polyurethane foam (SPF roofing)
This roofing is a foam based material that is achieved by the mixture and application of a two part liquid. That liquid is applied to the base of the roofing surface. When considering the application of that liquid its thickness can vary depending on your property and the suggested drainage slope or insulation value. One of the liquids in the two part liquid protects your home from UV rays, fire and weather changes.
Ethylene Propylene Diene Terpolymer (EPDM)
EPDM roofing consists of a single ply of rubber membrane that is designed with the intent to be highly resistant to weathering,abrasion, wind, ultraviolet rays, hail, and ozone. These abilities make this roofing ne of the most environmentally and sustainable materials for roofs. The fact that it is a single ply also makes the repair of EPDM convenient, affordable and easy to accomplish.
