Roofing for Commercial Buildings
Commercial roofs are typically flat and low-sloped but can also be pitched. There are a variety of commercial roofing options depending on your goals and roof type.
Types of Commercial Roofing
Built-up roofing consists of 3+ layers of fiberglass and asphalt sheets covered with gravel or mineral mixtures.
This type of commercial roofing is flexible as you can adjust the roof composition and number of layers to your specific needs.
You can expect to pay between $5.50-$8.50/sq.ft. For the materials and installation, a built-up roof will typically last around 40 years.
Metal roofing is lightweight and versatile, with the advantage of being fire-resistant.
It can be installed directly over existing roofing and has the benefit of being stable and environmentally-friendly.
The cost of materials and installation for metal roofing is typically between $5.00-$10.00/sq.ft.
Metal roofing can last anywhere from 50 to 75 years.
Single Ply Membranes are a cost-effective and durable option for commercial roofing.
They are reliable for about 30 years with the opportunity for a secondary application.
Single-ply membrane roofing can be a cost-effective and sustainable option for weather in Florida.
Thermoplastic polyolefin (TPO) & Polyvinyl chloride (PVC)
TPO roofing and PVC roofing are plastic single-ply membranes that are lightweight and reflective.
They are resistant to weathering, as well as to chemicals and grease. TPO has the disadvantage of being less flame-resistant than PVC.
You can expect to pay about $3.50-$6.50/sqft for TPO and $6.50-$8.00/sqft for PVC.
Ethylene propylene diene methylene (EPDM)
EPDM roofing is a dark-colored polymer membrane ideal for colder climates.
EPDM easily stretches for ease of installation but can shrink and crack in warmer climates.
You can expect to pay $3.50-$7.50/sq.ft. For EPDM roofing, including materials and installation.
