What Staten Island weather does to a roof
Nor'easters peel shingles, especially near the water in South Beach, Midland Beach and Great Kills. Salt air wears out flashing and metal faster on the East and South Shores. Freeze-thaw winters crack sealants and open seams on flat-roofed extensions. Heavy summer storms find every weak spot at once.
That's why we inspect the whole roof, not just the stain on your ceiling, and why we recommend wind-rated architectural shingles and install new flashing on every replacement.

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…”
“I called a few roofers & Alter Phase was the only one that returned my call promptly & showed up the next day to give the estimate. They were very detailed in their explanation and immediately put me at ease. They showed up 3 days later and did the work in one day. Every worker on the job was courteous and friendly. My house now…”
“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…”

(929) 370-1552Residential roofing: common questions
What types of home roofs do you work on?
Asphalt shingle roofs, which are the most common on Staten Island, flat roofs on extensions, garages and attached homes (EPDM, TPO, modified bitumen), and metal roofs. We also repair skylights, gutters and siding.
Do you work on two-family and attached homes?
Yes. Two-families, semi-attached and attached townhouses are a big part of our work on Staten Island.
Are estimates really free?
Yes. We inspect your roof, take photos and give you a written estimate at no charge and with no obligation.
How do I know if I need a repair or a new roof?
A repair usually makes sense when the roof is under about 15 years old and the damage is in one area. If it's over 20 years old, leaks in several places or the deck feels soft, replacement is often the better buy. When it's close, we give you both prices.

Free inspection, photos of what we find and a written quote. If it only needs a repair, we'll tell you.
