Commercial Roofing in Rochester, NY
We install and replace commercial roofing across Rochester and Monroe County. Flat roof systems including TPO and EPDM, on warehouses, storefronts, and offices. We have over 20 years of experience with business owners and general contractors in quality commercial roofing services.
How Long Does a Flat Commercial Roof Last?
A flat commercial roof in Rochester lasts 20 to 30 years with TPO or EPDM, provided the seams, flashing, and drains are maintained. Most flat roofs do not fail across the field. They fail at the details, and those are fixable long before the whole roof is.
We work on occupied buildings. That means staging around your hours, keeping entrances clear, and leaving the site safe every night. If the membrane still has life in it, we say so and repair the details instead of quoting you a tear-off. Compare the membranes on our roofing materials page.
TPO membrane roofing

Residential and Commercial Roofing Materials for Rochester Buildings
Architectural & Designer Asphalt Shingles
Asphalt is the most common residential roof in Rochester for good reason. It handles our winters, it is affordable, and the architectural profiles look sharp on almost any home. We install GAF architectural and designer shingles as a full system, with underlayment, ice and water shield, and proper ventilation, not just the top layer.
- Architectural: GAF Timberline HDZ and OC TruDefinition Duration
- Designer: GAF Camelot II and OC Berkshire Collection
- As a GAF Certified Plus™ and Owens Corning Preferred contractor, we can register warranty coverage most roofers can't offer.
Standing Seam Metal Roofing
Metal outlasts shingles by decades and sheds heavy Monroe County snow instead of holding it. We install standing seam metal on homes and on commercial buildings across the region, with concealed fasteners and no exposed screws to back out over time.
- Standing Seam: concealed-fastener panels built to last 50+ years
- Metal Shingles: profiles that mimic slate and shake
- We install systems from the top metal roofing brands, each one backed by strong manufacturer and labor warranties.
TPO Roofing
TPO is the go-to single-ply membrane for flat and low-slope commercial roofs. It reflects heat, resists tears, and the seams are heat-welded rather than glued, which is why it holds up on warehouses, storefronts, and modern flat-roofed homes around Rochester.
- Heat-Welded Seams: fused together, no adhesive to fail
- Reflective White: cuts cooling costs in summer
- We install membranes from the most trusted TPO manufacturers, each backed by strong material and labor warranties.
EPDM Roofing
EPDM is the proven rubber membrane for flat and low-slope roofs. We install it on commercial buildings and on homes where a pitched roof is not an option, and it handles Rochester freeze-thaw cycles better than almost anything else.
- Fully-Adhered: bonded down for the cleanest, tightest finish
- Mechanically Fastened: fast, strong, cost-friendly
- We install membranes from the most trusted EPDM manufacturers, each backed by strong material and labor warranties.
Read Kaptein Contracting Reviews From Around Rochester, NY
It’s so nice when a quote and job expectations all come true! Kaptein gave us the best price for our roof tear-off, completed the job in one full day with a crew who was great and obviously hard working. They came back to review the work with us and assure all was completed to our satisfaction. Would 100% recommend without hesitation.

These guys came highly recommended and didn’t disappoint. We bought a house and were lied to about the age of the roof. These guys tore out three layers of shingles, a heap of rotten wood and put in a perfect roof with new ventilation and left the property impeccably clean all in about a day and for a very fair price. John’s a nice guy too. Highly recommend!
Bret Levick · Google Review
I can’t say enough good things about John Kaptein Contracting. Two years after installing our roof, they returned to inspect an issue that, after inspection, ended up being unrelated to their work. Not only did they check it thoroughly, but they also cleaned and repaired the gutters. Their dedication and exceptional service went above and beyond my expectations. Highly recommended!

Commercial Roofing Questions, Answered
Who does commercial roofing in Rochester, NY?
Kaptein Contracting roofs commercial and flat roof buildings throughout Rochester, NY, Monroe County, and Wayne County. We are a family-run, fully insured, GAF Certified Plus contractor, roofing Rochester since 2006. We install and repair TPO, EPDM, and standing seam metal on commercial buildings.
TPO or EPDM: which is better for my building?
TPO is a white single ply membrane that reflects heat and keeps cooling costs down. EPDM is black rubber, and it handles cold and movement well. On a Rochester building the choice usually comes down to the roof deck, the slope, and the budget.
Can you work while the building stays open?
Yes. Most of our commercial work is on buildings that stay open. We stage around your hours, keep entrances and walkways clear, and clean the site every night. Tell us what your operating hours are and we will build the schedule around them.
Does a leaking flat roof need full replacement?
Not always. Flat roofs usually fail at the seams, the flashing, and the drains, not across the whole field. If the membrane is sound, a repair costs a fraction of a replacement. We get on the roof and tell you which one you are looking at.
Financing for Commercial Roof Work
A commercial roof is a capital expense and the timing is rarely convenient. We offer financing with low monthly payments and $0 down on approved credit, so the building gets the roof it needs on a schedule that works.

Options available on approved credit. Checking your options does not affect your credit score.
