Signs your roof needs a repair
Call before a small leak becomes a ceiling, insulation and mold problem. These are the signs Staten Island homeowners usually notice first:
- Brown stains on a ceiling or walloften near a chimney, skylight or bathroom vent
- Missing, cracked or curling shinglesafter a nor'easter
- Granules in the guttersthe sand-like coating that protects shingles
- Daylight or damp wood in the attic
- Lifted or rusted flashingaround chimneys, walls and vents
- Water sitting on a flat roofover an extension or garage two days after rain

What we repair
Leaks
We trace water back to where it actually enters, often several feet from the stain on your ceiling, and fix the source instead of smearing sealant on the symptom.
Shingles
Wind-damaged, cracked and missing shingles replaced and matched as closely as possible to the rest of your roof.
Flashing
Chimney, wall, valley and vent flashing is the most common leak point we find on Staten Island homes. We replace it with new metal.
Flat roofs
Seams, blisters, punctures and standing water on EPDM, TPO and modified bitumen roofs over extensions, garages and attached homes.
Skylights
Failed seals and flashing around skylights. See skylight repair.
Storm damage
Emergency tarping, damage photos for your insurer, then a permanent repair. See emergency roof repair.
Why Staten Island roofs leak
Nor'easters drive rain sideways under shingles and peel them back, especially on exposed homes in South Beach, Midland Beach and Great Kills. Salt air near the water corrodes flashing faster. Freeze-thaw winters crack old sealant, and heavy summer storms overload gutters and flat-roof drains. A good repair deals with the cause, not just the drip.
Before you call: the honest answers

Will there be a mess?
No. We protect your yard and shrubs, take every scrap with us and clean up before we leave.
Are you licensed and insured?

How a repair visit works
- We inspect the whole roof, not just the spot you called about, and photograph everything we find.
- You get a written quote, usually within 24 hours, that explains the cause and the fix in plain English.
- We do the repair with materials that match your roof.
- We show you the finished work with photos and give you a written workmanship warranty.
Repair or replace? Our rule of thumb
Repair is usually right when the roof is under about 15 years old, the damage is in one area, and the shingles or membrane around it are still flexible. Replacement makes more sense when the roof is over 20 years old, leaks in several places, or the deck feels soft. When it's close, you get both prices. Leaning toward a new roof?

What Staten Island customers say
“Called them up thinking I needed a new roof and gutters. They stopped by the same day, gave me an assessment of everything and it turns out the roof was repairable. They didn't try to pressure me into any unnecessary work. Just simply he gave me a couple of prices depending on what I decided to do. They were able to schedule the job quickly for a few days later and by the middle of the afternoon everything was done and it looks great!”
“I called for an estimate for a new roof. The price they quoted was way below two other estimates I received. I was also told that it would take 1-2 days to complete. Everything Alter Phase Contracting Inc promised was delivered. They gladly supplied me with their licensing and insurance information. The warranty is printed on my…”
“Just WOW! I expected that this would take several days, they got my new roof done in just 1 day. The guys did a thorough job, from set up to clean up. The price quoted was the price I paid, no gimmicks. True Staten Islanders. My roof looks great, couldn't be more happier. Would recommend to anyone who asks.”
“Marke and his team did an excellent job on replacing my roof! He and his brother came to my house, climbed up the roof to investigate the condition unlike other contractors which were only using a drone to take pictures. He gave me honest opinion and options for replacing my roof. Great communication and very easy to work with during…”
“10/10 would recommend! This is the second time I've used this company, and they've been excellent both times. The first time was a few years ago for a full shingle replacement. Most recently, I called them back to repair my flat roof and gutter system after a rough winter caused pooling and a leak. They came out the very next day to…”
“Alter Phase Roofing Contracting is a very good company. My new roof they installed just in one day, very professional and responsive. Clean very nice after the job and very friendly. The new roof has withstood several heavy rainstorms without any leaks. They are very respectful to come back inspected whole roof to make sure no any…”

(929) 370-1552Roof repair: common questions
How much does roof repair cost on Staten Island?
Minor repairs such as a few shingles or a pipe boot cost $150 to $400. Moderate repairs such as flashing replacement or leak tracing cost $400 to $1,500. Extensive storm or deck repairs cost $1,500 to $3,500. You get an exact written price after a free inspection.
How do I know if I need a repair or a new roof?
A repair usually makes sense if the roof is under about 15 years old and the problem is in one area. If it leaks in several places, sags, has widespread curling or missing shingles, or is over 20 years old, replacement is often cheaper in the long run. When it's close, we show you photos and give you both prices.
Can you repair a roof in the rain or snow?
We can stop the water in almost any weather with an emergency tarp or temporary seal. The permanent repair happens once the roof is dry and safe to work on, usually within a few days.
Do you warranty roof repairs?
Yes. Every repair comes with a written workmanship warranty. If the area we fixed leaks again, we come back.
Will homeowners insurance pay for my roof repair?
Insurance usually covers sudden damage from storms, wind or falling trees, not wear and age. We photograph and document the damage so you have what your insurer asks for.
How fast can you come out?
For active leaks we offer same-day emergency response, 24/7. For non-urgent repairs we usually schedule the inspection within a few days and send a written estimate within 24 hours.
