What's going on with your roof?
Pick what you're seeing. We'll tell you what it usually means, what Staten Island homeowners typically pay to fix it, and what to do next.
Water stain on a ceiling
What it usually means
Usually a leak at the flashing around a chimney, vent pipe or skylight, or a worn spot in the shingles. Water travels, so the stain is often several feet from the actual hole.
Typical cost on Staten Island
$300–$650 for most small leaks · flashing $450–$900
Missing or curling shingles
What it usually means
A few missing shingles after a nor'easter is a quick repair. Shingles curling or cracking all over the roof mean it is near the end of its life, and patching will not hold for long.
Typical cost on Staten Island
$350–$800 for a shingle repair
Roof is 20+ years old
What it usually means
Asphalt roofs last 20–30 yrs. A free inspection tells you how many good years are left, so you can plan a replacement instead of reacting to a leak.
Typical cost on Staten Island
$10,000–$30,000 for most Staten Island homes
Leak on a flat roof or extension
What it usually means
Flat roofs over rear extensions, garages and attached homes leak at seams, at the wall flashing and where water ponds. We fix the leak and the drainage that caused it.
Typical cost on Staten Island
$400–$1,200 to repair · new 1,000 sq ft flat roof $8,000–$13,000
Storm damage or water coming in
What it usually means
Call now, day or night. We stop the water with an emergency tarp or temporary repair, photograph everything for your insurance, then schedule the permanent fix.

Emergency line answered 24/7
Leaking skylight or overflowing gutters
What it usually means
Skylight leaks are usually failed flashing or seals, not the glass. Overflowing gutters push water behind your fascia and siding, and into the basement.
Typical cost on Staten Island
Skylight leak $500–$1,200 · gutter repair $150–$500

We know Staten Island roofs, house by house.
From high-ranches in New Springville to colonials on Todt Hill and townhouses in Annadale, every type of home has its own weak spots. We know where to look.
Colonials & capes
Steep shingle roofs, usually 1,500–2,500 sq ft. Watch the chimney flashing and the sunny south-facing slope, which wears out first.
High-ranch homes
Low-pitch shingle roofs, often with a flat section over the garage. The joint where flat meets sloped is the classic leak spot.
Semi-attached & townhouses
Your roof meets your neighbor's. We pay close attention to the seam and flashing at the shared wall, where most of these leaks start.
Homes near the water
South Beach to Tottenville gets the most wind and salt air. Shingles must be nailed to high-wind specs and flashing must resist corrosion.

(929) 370-1552Roofing questions and answers
How much does a new roof cost on Staten Island?
Most Staten Island roof replacements cost $10,000–$30,000. Asphalt shingles run about $5–$10 per square foot installed, so a typical detached house with about 1,800 sq ft of roof lands around $9,000–$18,000. A 1,000 sq ft flat roof is about $8,000–$13,000. You get an exact, written price after a free inspection.
How much does roof repair cost on Staten Island?
Most roof repairs on Staten Island cost $300–$1,200. A small leak patch is $300–$650, a shingle repair $350–$800 and new flashing $450–$900. Larger storm or deck repairs can run $1,500–$3,500. The inspection and written estimate are free.
How do I choose a roofing company on Staten Island?
Check five things before you sign. Ask for the NYC DCWP Home Improvement Contractor license number and a certificate of insurance. Make sure someone actually climbs your roof and shows you photos, not just drone shots. Get an itemized, written estimate and the warranty terms in writing. Then read the reviews: Alter Phase Roofing Contracting is license #2129904-DCWP, GAF Certified® and rated 5.0 stars from 154 reviews.
Do I need a new roof, or can it be repaired?
If your roof is under about 15 years old and the damage is in one area, a repair usually makes sense. If it leaks in several places, the shingles are curling or brittle all over, or it is over 20 years old, replacement is usually cheaper in the long run. We show you photos and tell you honestly. Many homeowners who call us about a new roof end up with a repair.
How long does a roof replacement take?
Most Staten Island homes are done in a single day. We tear off the old roof, inspect and repair the deck, install the new system and clean up before we leave.
Do I need a permit to replace my roof on Staten Island?
Not always. Replacing shingles like-for-like usually does not need a NYC DOB permit, but replacing the deck, changing the roof type and some full replacements do. We check this for every job and file the permit for you when it is needed.
Will you help with my insurance claim after storm damage?
Yes. We document the damage with photos and a written report you can send to your insurance company, make emergency repairs to stop further damage, and explain what the permanent repair involves.
Are you licensed and insured?
Yes. Alter Phase Roofing Contracting is a licensed NYC Home Improvement Contractor (DCWP license #2129904-DCWP), fully insured, GAF Certified® and BBB accredited.
What warranty do I get on a new roof?
Up to 50 years from the manufacturer on materials and up to 25 years on our workmanship, in writing.
Find out what your roof really needs.
Free inspection, photos of everything we find and a written price, usually within 24 hours. If a repair will do, we'll say so.
