Roof Replacement in New Haven County, CT
Tear-off and replacement with architectural shingles rated 110–130 mph — most homes finished in 1–2 days, yard left spotless.
Is It Time for a New Roof, or Can It Wait?
Most homeowners in New Haven County don’t think about their roof until they spot telltale signs: curling shingle edges, dark streaks spreading across shaded slopes, granules piling up at downspout exits, or water spots blooming across a second-floor ceiling after a driving rain. When a roof crosses the 18- to 22-year mark, the asphalt dries out, the fiberglass backing turns brittle, and a single nor'easter can tear off entire sections.
The anxiety is always the same: "How bad is it really, and is someone going to try to sell me something I don’t need?" In Connecticut's harsh climate—where sub-zero winter freeze-thaw cycles follow heavy summer humidity—waiting too long turns a manageable planned replacement into an emergency involving rotted rafters, ruined drywall, and saturated insulation.
We also hear often about the temptation to "just lay new shingles over the old ones." Here is our honest answer: while Connecticut code technically permits a second layer under specific structural conditions, we almost always advise against an overlay. Adding thousands of pounds of dead weight over brittle shingles traps heat, cuts your new roof's lifespan by up to 20%, and prevents anyone from seeing rotted plywood deck seams. A clean tear-off gives your home a fresh, warrantied start built to modern code.

Our Roof Replacement Process
No subcontractors, no guesswork. Every replacement is completed by our experienced in-house crew using specialized equipment that protects your home and landscaping.
Free Photo Inspection & Exact Quote
We inspect your roof deck, flashing, and attic ventilation in person. You receive a digital photo report and a line-item written estimate—never a ballpark guess on the back of a business card.
Yard Protection & Clean Tear-Off

We install wind-rated Owens Corning Duration® architectural shingles, ridge vents, and new flashings. Most jobs finish in 1–2 days, concluding with multiple magnetic sweeps of your lawn and driveway.

Engineered to Connecticut Building Code & New England Climate
Connecticut weather places severe demands on residential roofs. Between nor'easters off Long Island Sound, heavy winter ice damming, and shaded, damp tree canopies, your roof replacement must be installed to precise regional code:
24" Ice & Water Shield Code
Per CT State Building Code, ice barrier membrane must extend at least 24 inches inside the interior heated wall line (requiring two full courses on low-slope overhangs) and line every valley, chimney, and skylight to prevent winter ice dam backups.
110–130 MPH Wind Ratings
Duration® architectural shingles are rated for 110–130 mph winds using a 6-nail fastening pattern. This prevents blow-offs and shingle lift during coastal tropical storms, nor'easters, and severe thunderstorm downdrafts.
Algae & Moss Resistance
Heavily wooded lots in Cheshire, Hamden, and Woodbridge suffer from blue-green algae and lichen. StreakGuard™ protection uses copper-releasing granules to keep shaded Connecticut roof slopes clean and stain-free.

Frequently Asked Questions About Roof Replacement
Straightforward answers to the most common questions Connecticut homeowners ask us about replacing their roof.
In Connecticut, a full tear-off and replacement typically ranges from $9,000 to $18,000, with most average-sized single-family homes (around 2,000–2,500 sq ft of roof area) landing between $10,700 and $13,600 for architectural shingles.
The exact cost depends on roof square footage, pitch/steepness, number of existing layers to strip, complexity of valleys and dormers, and whether any rotted plywood decking needs replacement (typically $75–$95 per 4x8 sheet). Kelley provides upfront, written line-item proposals with guaranteed fixed pricing and financing options.

Have a timeline question? Call our Cheshire office at (203) 271-2926 →While Connecticut building code allows a second layer of shingles under narrow structural conditions (if only one layer currently exists and the decking is flat), we almost always advise a full tear-off.
An overlay traps attic heat, reduces new shingle lifespan by 15–20%, adds thousands of pounds of dead weight to your framing, and prevents us from inspecting the underlying plywood for soft spots or hidden leaks. Most importantly, code-mandated ice & water shield cannot adhere properly over old shingles. We will inspect your roof and tell you straight what makes financial sense.
Request a free on-roof photo inspection to see what's underneath →Every replacement includes the standard Owens Corning manufacturer warranty on Duration®-class architectural shingles, covering material defects, 110–130 mph wind resistance, and algae resistance.
