Residential Roofing for Westchester Homes
Colonials, Tudors, Victorians and mid-century ranches — plus the porch roofs, dormers and additions that make every Westchester roof a little different from the last.
Houses, not templates
Built for the homes that are actually here
Westchester's housing stock is unusually varied for a county its size. A 1920s Tudor in Bronxville, a postwar ranch in Yorktown, a 1990s colonial in Rye Brook and a Victorian in Tarrytown were built with different roof structures, different ventilation assumptions and different materials — and each one fails in its own way.
That variety is why a generic roofing approach doesn't work here. Slate roofs need a contractor who can source matching stone and reset courses without cracking the field. Cedar needs someone who understands that shade and moisture, not sun, destroy it. Low-slope porch roofs and additions need membrane work, not a shingle laid on a 2/12 pitch where it was never meant to go.
We work on all of it, with the same standard: diagnose properly, repair what can be repaired, and document everything so you know what you paid for and why.
- Slate, cedar, copper and standing-seam details
- Architectural shingle repair and replacement
- Porch, dormer and addition low-slope roofs
- Gutter, leader and fascia coordination
- Attic ventilation and insulation interface
- Annual maintenance for older roofs
"The right repair respects how the house was built — not how it would be built today."
Our standard on every job
What we handle
What we do on residential roofs
Everything from a single cracked slate to a full tear-off, on the same crew and the same standard.
01
Older-home specialists
Slate, cedar, copper and plaster-era framing handled by crews who know how to work on roofs that were never designed to be disassembled quickly.
02
Dormers & complex geometry
Dormer cheeks, valleys and roof-to-wall transitions — the details where most complex roofs leak and most contractors improvise.
03
Additions & low-slope
Porch roofs, sunroom additions and garages re-covered in EPDM or TPO with drainage corrected, instead of shingles fighting a flat pitch.
04
Ventilation & ice dams
Intake and exhaust balanced, bath and kitchen exhaust routed out rather than into the attic — the durable fix for ice dams and attic condensation.
05
Gutters & drainage
Gutter sizing, hangers, leaders and extensions corrected so the water that leaves the roof also leaves the foundation.
06
Maintenance plans
Annual inspection and minor repair for slate, cedar and copper roofs, so small failures get handled before they take out a ceiling.
When to call
What we look for on an older roof
On a 60- or 100-year-old roof, the material is rarely the problem. These details are.
- Flashing that has been patched with sealant instead of replaced
- Slipped or missing slates near valleys or chimneys
- Cedar shakes that are cupped, split or holding moss
- Gutter aprons and drip edge rusted through
- Bath fan exhausting directly into the attic
- Ice forming along one section of eave every winter
- Sagging between rafters visible from the street
Working with the village and historic review boards
Several Westchester villages review exterior work, and a handful of properties sit in historic districts where material changes need approval. We'll tell you up front whether your project is likely to need a review, what the application involves, and how we document the existing materials so the approval reflects what's actually there.
For slate and cedar homes, preserving original material is usually the fastest path through review and the better financial decision. Restoring a sound 90-year-old slate roof generally costs less than a synthetic replacement and protects the character that drives the home's value.
The low-slope addition nobody wants to fix
Almost every older Westchester home has one: a rear addition, a porch roof, or a bump-out with a 2/12 pitch that was shingled anyway. It leaks, gets patched, leaks again, and eventually rots the framing beneath.
The durable answer is a membrane system — EPDM or TPO — installed over a properly prepared deck with the drainage corrected so water doesn't pond. It's usually a one- or two-day job, and it stops the cycle of annual patching that never quite works.
Roofing and everything attached to it
A roof repair often touches more than the roof. Gutters and leaders need to handle the water the roof sheds; fascia and soffit need to be sound for the ventilation to work; and the attic needs to be sealed and insulated correctly for ice dams to stay away.
We'll flag those items in the estimate when they matter — not as an upsell, but because fixing the roof while leaving the drainage or ventilation broken means you'll be calling someone again next season.
"Two other roofers told us we needed a full replacement. Westchester Roof Repair found the actual leak at the chimney flashing, fixed it in an afternoon, and we've had a dry ceiling all winter."
Dana R.
Scarsdale, NY · Chimney flashing repair
"They replaced a section of our slate roof with salvaged stone that matches the 1920s original. You cannot tell where the repair starts. The crew swept the driveway twice before leaving."
Michael P.
Bronxville, NY · Slate repair
"A nor'easter took shingles off at 11pm. They were out with tarps before morning and had the insurance photos ready before the adjuster called."

Common questions
Straight answers
What homeowners ask us before booking this work.
Do I actually need a new roof, or will a repair do?
In our experience, most failing roofs in Westchester are failing at one detail: flashing at a chimney, a valley, a skylight or a wall intersection. If the field of shingles or slate is sound, a repair is the better investment. If the deck is saturated or the underlayment has failed across the roof, we'll show you why a replacement is the only durable answer.
Can you repair slate and cedar without replacing the whole roof?
Usually, yes. Slate and cedar are designed to be maintained. We replace broken slates or shakes, re-flash the penetrations, and match material from salvage or mill runs. Keeping a 100-year slate roof alive is almost always cheaper and better than replacing it.
What causes ice dams on Westchester roofs?
Ice dams are a ventilation and insulation problem that shows up on the roof. Warm attic air melts snow, it refreezes at the cold eave, and water backs up under the shingles. Clearing the ice is temporary; correcting intake and exhaust ventilation and air sealing the ceiling plane is the fix, and we build that into repair and replacement work.
Is there a warranty on your repairs?
Every repair carries a written workmanship warranty, and full replacements include manufacturer material warranties that we register for you. The terms are on the estimate before you sign anything.
