Flat roofs, TPO membrane, modified bitumen, and low-slope systems for Sonoma County commercial buildings. Licensed, experienced, no subs.
From small retail buildings to large industrial flat roofs — we're licensed for commercial work throughout Sonoma County.
We work around your business schedule — not the other way around.
We walk your commercial roof, document existing conditions, measure square footage, and identify problem areas. We take photos and provide a full written assessment.
We recommend the right membrane system for your building's slope, drainage, and exposure. Not every building needs TPO — we recommend what actually fits.
You receive a detailed written proposal with material specifications, scope of work, and schedule. We coordinate work during off-hours if your operation can't be disrupted.
Our crew handles commercial installations without subcontracting. We work clean, respect your tenants and customers, and minimize disruption.
We conduct a final inspection, walk the roof with your facilities team, and provide all warranty documentation including manufacturer's and workmanship warranties.
TPO, EPDM, and modified bitumen systems installed on commercial properties throughout Sonoma County.
"Sutter replaced the roof on our Santa Rosa office building — 8,200 sq ft of TPO. They worked around our business hours, completed the job in 4 days, and the post-job cleanup was spotless. The manufacturer warranty documentation was ready within 48 hours."
"Our Petaluma retail center had ongoing EPDM issues that two previous contractors couldn't solve. Sutter diagnosed the drainage problem, spec'd the right repair, and it's been leak-free for 18 months. Finally."
"We have three commercial properties in Rohnert Park. Sutter is the only commercial roofer we use — competitive pricing, proper spec sheets, and they understand the difference between a patch and a real fix."
