Commercial Roofing Shapes that Stand the Test of Time
If you’ve been browsing, ‘What is commercial roofing?’, you’re probably curious about how they’re different from residential roofs. As compared to residential roofs, commercial roofs focus on a structure that guarantees long-term protection against the elements and come in very limited shapes.
Let’s look at the two most common forms or shapes of commercial roofing systems:
a. Flat roofs: The popular choice
Low-slope roofing systems have a pitch under 18 degrees and lack shingles. Using flat roof systems for commercial buildings is a very popular choice for facilities having much more square footage than a residential site. They are usually made of durable materials like metal, EPDM, modified bitumen, or factory-certified TPO. However, without the proper installation or drainage, even your low-slope roof can leak.
b. Own a smaller business? Pick a pitched roof
Steep-sloped or pitched commercial roofing systems have a pitch of 18 degrees or more and are suitable for religious congregations or small commercial businesses. They provide an attic space through their A-frame design. They’re mostly made of composite or synthetic tile, metal, slate, asphalt, or concrete.
