Roofers in Thornwood, NY
A roof inspection in Thornwood usually starts with a question the homeowner already half-knows the answer to: is that dark streaking on the north slope just age, or is something actually failing? Thornwood is a small, heavily wooded hamlet in the Town of Mount Pleasant, and most roofs here sit under mature oak, maple and pine. That canopy does more to shape a Thornwood roof’s condition than the calendar does. We’re Ashton Roof Repair, and we handle inspection, repair and replacement under one company. Call (833) 741-8977 to schedule your free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Thornwood Homes Are Different
The tree cover is the whole story here. Roofs in Thornwood spend much of the year in shade, and shaded roof planes stay damp after rain far longer than open ones. Moss and lichen become a recurring seasonal problem rather than an occasional one, and black algae streaking on north-facing slopes is about as common a call as we get in the 10594 area. Fall brings a second problem: pine needles and leaves pack into valleys and behind chimneys, where they hold water against the shingles instead of letting it run off.
The housing stock adds to it. Thornwood’s homes are mostly mid-century to late-20th-century single-family colonials, splits and ranches on wooded half-acre-plus lots off Broadway and Marble Avenue, most with asphalt shingle roofs. Dormers and rear extensions were added to many of them over the years, which creates complex valleys and flashing junctions where water has more chances to find a way in. Cold, snowy winters bring ice dams at the eaves, and humid summers keep those shaded planes wet. It’s a humid continental Hudson Valley climate, and roofs here show every bit of it.

Our Main Thornwood Services
Most Thornwood homeowners call us about one of two things: a roof that’s leaking or damaged, or a roof they suspect has reached the end of its life.
Roof Repair in Thornwood
Repair work in Thornwood tends to be about the details rather than the field of the roof. Limb-drop impact damage after a summer storm, flashing that’s given out at a dormer or chimney, or shingles under a shaded valley that never fully dried out. When we look at a repair, we check the whole junction, not just the torn shingle, because water travels. We work across GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko and Boral, so patching a roof means matching what’s already there rather than substituting whatever happens to be on the truck. For the full scope of what we fix, see Roof Repair in Thornwood.
Roof Replacement in Thornwood
Replacement decisions in Thornwood usually come down to whether the decking under a shaded roof has stayed sound. A tear-off lets us see the sheathing, replace what’s soft, and correct the ventilation that keeps a canopy-shaded roof from trapping moisture. Because we install across seven manufacturers, we can compare a premium line against a value line honestly and let the roof and the budget decide. If your roof is past patching, read more about Roof Replacement in Thornwood.
Roof Inspection in Thornwood
Roof inspection in Thornwood is mostly about reading shade. Roofs here sit under mature oak, maple and pine canopy, so the failure modes we look for are organic: moss and algae on north slopes, debris packed into valleys and behind chimneys, and limb impact after summer storms. A roof that looks fine from the driveway can be holding moisture in three places you can’t see. We offer Roof Inspection as a standalone service, with no repair purchase required, so you get an honest condition assessment before anyone quotes you a job.
Roof Inspection Services
Signs you need it
You need an inspection if you’re seeing dark streaking or green growth on a shaded slope, granules collecting in the gutters, or a ceiling stain that appears after heavy rain.
What it costs in Thornwood
A standard roof inspection in Thornwood typically runs $150 to $350, and a free inspection is available when you’re pricing a repair or replacement.
How we do it
We walk the roof and the attic, check valleys, flashing and chimney junctions, photograph what we find, and give you a written condition report with our recommendation ranked by urgency.
Hail Damage Roof
Signs you need it
Hail is uncommon here, so the impact damage we actually find in Thornwood comes from falling limbs and debris, showing up as bruised or fractured shingle mats, dented flashing and granule loss in patches.
What it costs in Thornwood
An impact-damage assessment typically runs $150 to $350, and the repair itself is quoted separately once we know what’s damaged.
How we do it
We inspect the slopes and ridges for impact marks, check the gutters for displaced granules, and document the damage in writing so you can decide between a targeted repair and a larger job.

What Thornwood Customers Say
"Storm took part of the ridge off at night. They tarped it the same evening so the rain didn't get in, and did the real repair the following week."
- Lamont Ellison"Leak over the kitchen turned out to be a cracked boot around a vent pipe, not the roof itself. He showed me the photo from up there and replaced the boot for a couple hundred dollars. The company before him had quoted a full tear off."
- Holly Reed"Flashing where the roof meets the chimney had never been done right by the original builder. He rebuilt it properly with step flashing instead of just running a bead of caulk over it like the last two people did."
- Eric Hayes
