Roof Repair explained
Roof repair means fixing a specific defect without replacing the whole roof. The key step is finding where water actually enters, which is often several feet from the stain inside. A repair makes sense when the surrounding roof is sound and the problem is local: a failed flashing, a few damaged shingles, a split seam, a bad penetration seal. If the roof is widely worn out, patching it over and over can cost more than it saves, and we will say so plainly. Repairs are matched to your existing roof type, whether asphalt shingle, modified bitumen, EPDM, TPO or built-up.
Options and materials
Flashing repair
Replacing or resealing flashing at walls, chimneys, vents and skylights, which is where most NYC roof leaks start because metal, masonry and roofing all move differently with the weather.
Shingle and slope repair
Replacing damaged, missing or lifted shingles and exposed fasteners on pitched roofs, and matching the existing roof as closely as the currently available material allows.
Membrane and seam repair
Patching punctures, re-welding or re-adhering open seams, and restoring terminations and edges on flat and low-slope roofs so water stops getting under the membrane. We walk you through this option in plain language.
Sealant and penetration work
Rebuilding pipe boots, vent collars and drain surrounds. These are small parts that cause outsized leaks when they fail, and they are often overlooked during quick patch jobs.
Decking and substrate repair
Cutting out and replacing soft or rotted decking or wet insulation beneath the roof surface before the new covering goes down, so the repair has a sound base to bond to.
Our process
- Inspection and leak tracingWe inspect the roof surface, flashings and penetrations, then compare what we find with the interior damage to locate the true entry point, not just the stain.
- Written estimateYou get a clear written scope covering what will be repaired and with what materials, plus any related issues we noticed but are not including in the price.
- Site protectionWe protect landscaping, walkways and entries, set up safe roof access, and keep the work area contained so your property stays clean and safe.
- RepairFailed components are removed back to sound material and replaced with compatible materials, instead of being covered over with another surface coat of sealant or tar.
- Testing and cleanupWe check the repaired area, sweep the property, remove all debris, and use a magnetic sweep where shingles or nails were handled during the work.
- Photos and warrantyYou receive photo documentation of the finished work and a written workmanship warranty. The terms are written into your contract for you to review before you sign.
What affects the price
Size of the affected area
A single flashing or a few shingles is a quick visit. Repairs spread over several sections of the roof take more labor, more material and more time on site.
Roof type and material
Shingle, modified bitumen, EPDM, TPO and slate each need different materials and different skills, which affects both the labor involved and the parts required.
Access and height
Tall buildings, rear roofs, tight lots and roofs reached only through a bulkhead can require extra setup, hoisting and protection before any repair work begins.
Hidden damage
Wet insulation or rotted decking found once the surface is opened adds scope. We flag this in writing and explain it before any extra work proceeds.
Roof age and condition
An older roof may need a wider repair so the patch has sound material to bond to, which changes the amount of material and labor the job takes.
Urgency
Emergency and after-hours leak stops are priced differently from scheduled repairs because of the crew, equipment and response time involved in getting there fast.
Getting a price
Because these factors change from roof to roof, we don't publish one-size-fits-all prices. We inspect your roof for free and give you a written, itemized estimate before any work starts.
