CertainTeed Roof Repair in New York City: What to Know First
We provide independent CertainTeed roof repair in New York City, with most calls completed same-day or next-day and pricing given upfront before any work begins. A typical CertainTeed shingle repair runs $280-$520, while flashing or valley work on their architectural lines usually falls between $340-$780. We are not affiliated with CertainTeed Corporation; we are an independent CertainTeed service provider that stocks the right parts and knows how their products behave in New York City’s freeze-thaw cycles.
This page is for homeowners who know they’ve got CertainTeed on their roof and want it fixed by someone who understands the difference between a Landmark PRO failure and a NorthGate issue. If that’s you, call us at (866) 756-1978. A live person answers, 24 hours a day.
How CertainTeed Products Fail - and How We Fix Them
- Landmark and Landmark PRO: granular loss on south-facing slopes. In New York City, the combination of summer UV reflecting off brick and asphalt, followed by hard winter freezes, accelerates granule shedding on these popular architectural shingles. We see this most in Queens row houses and Brooklyn brownstones with minimal roof pitch. Our fix: we source matching color lots from our supplier network, replace the affected courses, and seal with CertainTeed-approved asphalt cement rather than generic caulk, which preserves any remaining material warranty coverage.
- NorthGate SBS-modified shingles: nail pull-through in high-wind events. The rubberized asphalt in NorthGate makes it flexible, but the thicker shingle body can mask insufficient nail penetration. After Sandy and the nor’easters that followed, we found dozens of NorthGate roofs in Staten Island and the Rockaways with nails that held the deck but pulled through the shingle itself. We repair with ring-shank nails at the manufacturer’s specified exposure and add six nails per shingle in wind zones, not four.
- CertainTeed flat roofing (Flintlastic SA and modified bitumen): seam separation at parapet walls. New York City’s building movement, thermal expansion on black surfaces, and the relentless freeze-thaw of January through March open seams where the parapet meets the field. We’ve learned to cut back to sound substrate, re-prime with Flintlastic-compatible asphalt primer, and re-roll seams with a proper weighted roller, not hand pressure. Shortcut this, and the seam lifts again in eighteen months.
- Integrity Roof System components: ridge vent collapse or clogging. CertainTeed’s Ridge Vent with MoistureGuard can compress when over-nailed or when squirrels nest in the gap. In the Bronx and upper Manhattan, where mature oak and maple overhang roofs, we also see the filter mat clog with helicopter seeds and leaf debris. We replace crushed vent sections with OEM profile-matched pieces and install animal-proof external baffles where the original design failed.
- Presidential Shake and luxury shingles: individual shingle blow-off due to excessive exposure. These heavy, laminated shingles tempt installers to stretch courses for speed. The result: a 5-inch exposure where 4 inches was specified, and the adhesive strip never engages properly. We measure every course on repair jobs, replace with the correct exposure, and hand-seal the first winter until ambient temperatures allow proper thermal sealing.
Our CertainTeed Roof Repair Process
- 1
Call and schedule. You reach a live person, not a menu. We ask what you’re seeing, when it started, and whether you know your shingle type. If you don’t, we figure it out on arrival.
- 2
Photo-documented inspection. Our technician walks your roof in uniform, photographs the damage, and identifies your CertainTeed product line by pattern, thickness, and color code. We show you the photos on a tablet before we discuss solutions.
- 3
Parts decision: OEM or quality equivalent. For current lines like Landmark PRO and NorthGate, we stock OEM CertainTeed shingles and accessories. For discontinued lines like the original Horizon or Independence, we source from our network of regional distributors or match with a quality aftermarket product that meets ASTM D3462, explaining the trade-off before you decide.
- 4
The repair. We work to CertainTeed’s published installation guidelines, not generic practice. Nail placement, exposure, cement type, and underlayment integration all follow the manual. Sal Benedetto checks the flashing details personally on jobs over ol,000 - he’s known in the trade for getting them right the first time.
- 5
Water test and cleanup. Where accessible, we run water on the repair area with a hose and check the attic or top-floor ceiling for intrusion. We magnet-nail sweep the perimeter and bag all debris before we leave.
- 6
Written guarantee. Every repair is backed by our 90-Day Done Right Promise. If it’s not right, we come back and make it right. No paperwork to file, no argument.

FAQs
No, if the repair is done with CertainTeed-compatible materials and follows their installation guidelines. We use OEM shingles and accessories on current lines, and we document our work with photos in case you ever need to file a warranty claim. If you’re unsure about your warranty status, call us at (866) 756-1978 and we’ll help you sort it out.
For active lines like Landmark PRO and NorthGate, we stock them in our Queens warehouse and can usually repair same-day or next-day. Discontinued lines take 2-4 business days to source from our regional distributor network. If you have an active leak, we’ll tarp and seal temporarily while we wait for the exact match.
If you’re facing one or two isolated issues and the roof is under fifteen years old, repair is almost always the better value. If you’re seeing widespread granular loss, multiple leak points, or the roof is past twenty years, replacement becomes the more economical choice. We’ll tell you which side of that line you’re on, honestly. Call (866) 756-1978 for a free inspection.
On current production lines, yes, we match by color code from CertainTeed’s active palette. On discontinued lines, we source from distributor overstock or match to the closest available architectural shingle, showing you the sample before we install. New shingles always weather slightly differently than aged ones for the first two seasons, which we explain so you’re not surprised.
Yes. We’re authorized installers for seven manufacturer brands including GAF and Owens Corning, and we repair all of them. If you’re not certain what’s on your roof, we’ll identify it during inspection and proceed accordingly.
