Flat Roofing Installation for Additions & Low-Slope Roofs
"Flat" roofing is never actually flat — it's low-slope, typically under a 2:12 pitch, and it requires a completely different water-management approach than shingles or metal. Water doesn't run off a low-slope roof, it has to be directed to drains, which means membrane material and installation precision matter more here than on any pitched roof type.
What's Involved
We install TPO and EPDM membrane systems, both heat- or adhesive-sealed at the seams rather than nailed like shingles. Proper slope-to-drain design during installation is what prevents ponding water, which is the single biggest cause of flat roof failure. These systems typically run 20-25 years before replacement with proper maintenance.
How This Differs
This page covers low-slope applications specifically — additions, porch roofs, or sections of a home with minimal pitch. It's not a residential shingle alternative; if your roof has a standard pitch, Asphalt Shingle Roofing or Metal Roofing Installation is the right fit. Full commercial flat roofing is covered on our Commercial Roofing page.
Local Conditions
Heavy rain events have become more frequent in coastal Connecticut in recent years, which makes proper drainage slope on any low-pitch section in towns like Fairfield or New Haven more important than it might have been on a roof built decades ago to older standards.
