Whether you’re budgeting for a roof replacement, weighing a repair, or just trying to understand what’s on top of your building, the same questions come up again and again. We’ve gathered the ones we hear most and answered them honestly below, grouped by topic.

If your question isn’t here, the fastest way to a real answer is a free inspection — we’ll look at your specific roof and tell you exactly where it stands.

Roofing Systems

What types of commercial roofing do you install?

We install all major low-slope systems — TPO, EPDM, and PVC single-ply membranes, metal and standing-seam roofing, spray foam (SPF), modified bitumen, built-up (BUR), and fabric-reinforced systems — plus restoration coatings. Because we install all of them, our recommendation is based on your building, not on a single product line.

Which commercial roofing system is best?

There's no single best system — it depends on your building's use, energy goals, and budget. TPO is a cost-effective reflective choice for warehouses and retail; EPDM is a durable, long-lived rubber roof for offices and schools; PVC resists grease and chemicals, making it ideal for restaurants and plants. A free inspection turns those trade-offs into a clear recommendation.

What is the most energy-efficient commercial roof?

Reflective white membranes like TPO and PVC bounce sunlight and keep rooftop temperatures down, which lowers cooling costs. Spray foam adds high R-value insulation in a seamless application. The best choice depends on your climate and building, but a reflective or well-insulated system can meaningfully reduce energy bills.

Cost & Budgeting

How much does a commercial roof cost?

Most commercial low-slope roofs run roughly $7.50 to $16 per square foot installed in 2026, depending on the system, while restoration coatings cost far less at about $2.50 to $6. Your exact number depends on roof size, system, condition, and access. See our cost guide for detailed ranges, then get an inspection for a precise figure.

What affects the cost of a commercial roof?

The biggest drivers are roof access and height, the number of penetrations and curbs, whether the old roof is torn off or recovered, the condition of the deck underneath, required insulation or code upgrades, and the warranty tier you choose. A crowded, hard-to-reach roof needing a full tear-off costs well above a clean, open recover.

Do you offer free estimates?

Yes. We provide free drone and infrared inspections with no obligation, then give you an exact, defensible price based on real measurements and your roof's actual condition — along with an honest recommendation, even if that's to repair rather than replace.

Repair vs. Replacement

Should I repair or replace my commercial roof?

It depends on the condition of the membrane, insulation, and deck. If leaks are localized and the insulation is dry, repair or restoration is usually the smarter spend. If the insulation is saturated or you patch leaks every season, replacement is the better long-term value. More than half of the roofs we inspect are repairable — an infrared scan settles which side of the line yours is on.

Is roof restoration a real alternative to replacement?

For the right roof, yes. A restoration coating on a structurally sound, dry roof can add 10 to 15 years of waterproof life for a fraction of replacement cost. It's not a fix for a roof with wet insulation or a failing deck, but on a sound roof it's often the best value available — and it defers a major capital expense.

Warranties

What kind of warranty comes with a new commercial roof?

There are two parts: a manufacturer warranty covering the membrane and a workmanship warranty covering installation. The strongest option is a manufacturer system warranty — including No Dollar Limit (NDL) coverage that pays for both material and labor — which is only available when a certified contractor installs the system to spec. As a certified installer, we can secure these on qualifying roofs.

What voids a commercial roof warranty?

Common warranty-killers include unauthorized repairs by an uncertified contractor, skipping required maintenance and inspections, adding rooftop equipment without properly flashing the new penetrations, ignoring ponding water, and failing to register the warranty. Keeping maintenance records and using approved contractors protects your coverage.
