Options In Roofing For Your Commercial Building

A commercial roof is usually quite different from the type of roof you have on your home. For one thing, the roofs are usually very low-sloped or flat. This makes them invisible from the street, so appearance isn't as important. Another difference is these roofs get more foot traffic since commercial HVAC systems and other equipment are mounted on them. Plus, being flat, a commercial roof is at higher risk of leaking, so the roofing material needs to be watertight. If your commercial roof is near the end of its life, here are some options to consider when you're ready to put on a new one.

Coated Roofs

Coated roofs are popular because they are inexpensive and easy to apply. However, your original roof has to be in fairly good condition because the coating is applied on top of it. If there is extensive damage from water leakage, those repairs must be made first and then the decision can be made on the best type of roof to apply. If your roofing contractor determines your roof is a good match for coating, then you'll get the benefit of a fully waterproof roofing material. The coating is sprayed or painted onto the roof, so it fills in cracks and folds itself around pipes and other protrusions through the roof. As it dries, it bonds with the surface in a single layer that keeps water from leaking through. These roofs are usually white, so they reflect UV rays, which keeps the roof cooler. This might even help with the energy costs for your building.

Metal Roofing

If your roof has an angle which makes it visible from the street, then appearances may be important to you. If that's the case, then metal roofing is a great option. The metal comes in various colors, so you can match the exterior of the building whether it is brick, concrete, or other material. Commercial metal roofing is applied in long sheets, and this makes it a good match for low slope roofs because there are fewer seams for water to leak through. Another benefit is that metal is practically maintenance free. A metal roof lasts for many years and it adds a layer of fire protection to your building.


EPDM roofing is quite versatile. It is a rubber roofing material that can be used on low slopes, steep slopes, and unusual shapes like domes. The rubber is waterproof, so it provides excellent protection from water. Plus, the material resists UV deterioration and it stands up to foot traffic. It is applied in sheets that are bonded together at the seams to create a waterproof barrier on your roof. This roofing material is lightweight, so it can be applied over an existing roof. It can be attached to the roof with adhesive, mechanically fastened, or applied loose-lay style. Loose-lay is for sloped roofs where water drains off by gravity while adhered EPDM is an ideal material for a flat roof that often collects water puddles during a rain.

The type of commercial roofing you choose depends on your budget and the slope of the roof. If you have a typical commercial flat roof, then you have the most options. In that case, you may want to also consider energy efficiency, longevity, and amount of maintenance the roof will need in the coming years. A roofing contractor can help you determine the condition of your current roof, which could also play a role in which roofing material is the best option.
