A guide to flat and commercial roofing in West Haven: what the work involves, what separates a solid contractor from a risky one, and how our rankings work.
Flat and low-slope roofs cover most of West Haven's commercial buildings, from storefronts along Campbell Avenue to warehouses near the harbor, plus a fair number of additions and garages on residential lots. This is a different trade than pitched-roof shingle work. Systems here typically include TPO, EPDM rubber, modified bitumen, or built-up asphalt roofing, and the details around drains, flashing, parapet walls, and seams matter more than the field material itself. Most leaks on flat roofs start at a transition point, not in the middle of a membrane.
We've profiled 8 contractors in this category who handle flat and commercial roofing work in the area. When comparing them, look at whether they carry manufacturer certifications for the specific membrane system they install, since that affects warranty length and what's actually covered. Check whether they offer roof inspections and maintenance plans rather than pushing straight to replacement, and whether they're used to coordinating with property managers or insurance adjusters on commercial jobs. It's also worth asking how they handle drainage and ponding water, which is the most common failure point on flat roofs in this climate.
Our scoring weighs licensing, insurance, verified reviews, response time, and the range of commercial services offered, so you can compare contractors on more than star ratings alone.

Over 14 consecutive five-star reviews, Solid Rock Roofing stands out for fast response times, transparent communication, and meticulous workmanship. Mikey and his crew consistently finish on schedule, manage flat roofs and full replacements with equal professionalism, and deliver quotes that undercut competitors without cutting corners.
Most jobs finish within a day or two. Manny and his crew show up when promised, price fairly, and leave the site clean. Reviewers consistently praise the speed and professionalism, especially on roof leaks, gutter installation, and emergency calls. One earlier appointment was missed, but 94 percent of reviews are five-star and recent feedback remains strong. Gutter work, roof repair, and full roof replacement are the most common jobs mentioned. Reviewers describe fast turnarounds, spotting hidden problems like roof rot, and quality materials. The business also handles siding repairs and other trades.
All 10 reviews award five stars. Customers consistently cite fair pricing, on-time work, and direct communication from Mike and Dan Perry. One reviewer noted About Time was the lowest bidder among multiple quotes and included painting in the price; another praised their handling of an insurance claim for storm damage across roof, siding, gutters, and windows.
Quality Roofing Services handles commercial and residential roofing across Connecticut with a track record built on large-scale projects. Reviewers consistently report professional execution, expert staff like Danny Young, and a history of repeat work on medical buildings, retail chains, and multifamily properties.
Most reviewers praise Michael's decades of hands-on experience and his crew's precision on complex cedar and metal roofing jobs. Two early accounts flag poor communication during the quoting phase and a warranty dispute that dragged on unresolved.

Colonial Exteriors earns high marks for single-home roof and gutter work, with owner Chris known to follow up personally. However, a major multi-unit project revealed serious delays and incomplete work over months, with workers appearing sporadically and the site looking neglected. This split suggests the company performs well on straightforward jobs but struggles with scope and coordination on larger builds.
Nations Roof holds a perfect 5.0 rating across three Google reviews. Review detail is limited, but available feedback indicates customers value their emergency response and professional service. The business operates across the West Haven and greater New Haven area.
