What to Expect from Our Process

Frequently Asked Questions

What commercial roofing systems do you install?

We install TPO (Thermoplastic Polyolefin), EPDM (rubber), modified bitumen, built-up roofing (BUR), and coatings. The best system depends on your building's structure, drainage, and budget — we walk through the options with you.

How do you minimize business disruption during roofing work?

We schedule work during off-hours when possible and work in sections so operations continue. We provide a detailed schedule before starting and communicate daily with your facilities manager about progress and access needs.

What is the lifespan of a commercial roof?

TPO and EPDM systems last 20–30 years with proper maintenance. Modified bitumen runs 15–25 years. Coatings can extend an existing roof's life by 10–15 years. Annual inspections significantly extend any commercial roof's useful life.

Do you handle HOA and multi-unit property roofing?

Yes — HOAs and multi-unit properties are a significant part of our commercial work. We coordinate with property managers, provide documentation for reserve studies, and can phase work to minimize disruption to residents.

Are commercial roof replacements eligible for tax deductions?

Commercial roofing work may qualify as a Section 179 deduction or bonus depreciation under current IRS rules. We are not accountants, but we provide detailed invoices and material documentation to give your CPA what they need.
