COMMERCIAL ROOFING IS COMPLETELY DIFFERENT THAN RESIDENTIAL ROOFING
The systems available for commercial buildings and their installation are quite different from residential roofing materials and techniques.
These two industries are not the same.
Commercial Roofing vs. Residential Roofing
Residential roofing systems usually use asphalt shingle and on occasion cedar, slate or metal depending on the location and climate. Commercial roofing has two major types that are most commonly used and they consist of Spray Foam or Single Ply applications.
Sprayed polyurethane foam, restoration coatings or single-ply (TPO, PVC, EPDM), modified bitumen, concrete, built-up, tar and gravel, and many others are some of the options available. In terms of variation there are more commercial roofing types available than residential types. Each have their own advantages and disadvantages and you should determine which fits your building best.
There is also an added time factor for replacing a commercial roof. The material used on a commercial roof will often require multiple days of waiting for products to set or settle.
The roofing system we mainly focus on due to popularity is:
EPDM (Ethylene Propylene Diene Monomer) is a highly flexible, rubber-like membrane that has been used in the commercial roofing industry since 1955. EPDM doesn’t offer the reflectivity benefits of PVC or TPO and it’s not as durable. It does offers some benefits, however. EPDM is extremely lightweight, making it versatile and allows for fast installation making it a very affordable roofing system that can last up to 20 years.
