Depending on your roof and the current condition, we have several options available for you.
TPO
TPO stands for Thermoplastic Polyolefin. This is a white PVC-like, single-ply membrane that is popular with commercial buildings and is relatively cost effective.
EPDM
Ethylene Propylene Diene Terpolymer is essentially a rubber-like roofing material. This too is a single-ply membrane and relatively cost effective. Also common on commercial building roof types.
Modified Bitumen
This is a rubber or plastic modified asphalt rolled roof. This can be installed with hot tar or cold tar. It can also be applied as a peel and stick and heated with a torch for adherence.
Coatings
We also have a variety of restorative options that include silicone, acrylic and elastomeric. These are meant to extend the service life of a commercial roof that isn't in need or replacement.

Most Common Commercial Roofing FAQs
The lifespan of a commercial roof can vary depending on several factors, including the type of roofing material, installation quality, maintenance practices, climate conditions, and other external factors. Approximate lifespans for common commercial roofing materials: Built-Up Roofing (BUR) lasts 15–30 years with proper maintenance; Modified Bitumen 20–30 years; Thermoplastic Olefin (TPO) 20–30 years; EPDM 20–30 years; Metal Roofing 40–70+ years; Asphalt Shingles 15–30 years.
Common signs that it may be time to replace your commercial roof include: age of the roof approaching or exceeding its expected lifespan; visible damage like cracks, splits, blistering, curling or buckling shingles, or missing or damaged tiles; water leakage or moisture stains inside the building; a sagging or bowed roof indicating structural issues; excessive energy costs from poor insulation or ventilation; and significant deterioration of the roofing material such as brittle shingles, rust on metal, or cracks on flat roofs.
On average, commercial roof installation ranges from $5 to $15 per square foot, though complex roofs with unique architectural features or multiple levels can cost more. By material: BUR $3–7/sq ft, Modified Bitumen $4–8, TPO $5–8, EPDM $4–8, Metal $7–12, PVC $6–10, Spray Polyurethane Foam (SPF) $5–10.
Timing depends on the size and complexity of the roof, materials, weather, and crew efficiency. A small-to-medium commercial roof with a simple design may take a few days to a couple of weeks, covering removal of the old roof, surface preparation, installation, and finishing. Larger or complex roofs with multiple levels or unique features may take several weeks or even months. Weather events like rain, snow, or high winds can cause delays.
The right choice depends on your specific needs, budget, location, and building requirements. Built-Up Roofing (BUR) provides excellent waterproofing and durability for low-slope or flat roofs. Modified Bitumen offers enhanced flexibility and temperature resistance. TPO is lightweight, energy-efficient, and reflective. EPDM offers strong weather resistance and flexibility. Metal Roofing is durable, long-lasting, and low maintenance. PVC provides excellent chemical, fire, and UV resistance, making it popular for restaurants and manufacturing. Consult with a professional roofing contractor to evaluate your building and recommend the best fit.
