Roofing in Arrochar: what we see on these homes
Arrochar is on Staten Island's East Shore, inland of Fort Wadsworth and South Beach and close to the Verrazzano-Narrows Bridge. It shares the 10305 ZIP code with our office at 61 Appleby Ave, so it's one of the quickest neighborhoods for us to reach.
Detached and semi-attached houses
Many Arrochar homes have pitched asphalt shingle roofs. On semi-attached houses, the joint where your roof meets your neighbor's needs careful flashing, and that's where many leaks start.
Two-families and attached homes with flat roofs
Two-family and attached homes often have flat or low-slope roofs. Open seams, worn flashing at the parapet or wall, and clogged drains are the usual causes of leaks, and we fix the drainage as well as the leak.
Wind near the Narrows
Homes closer to the water and the Narrows catch more wind, which lifts shingles and loosens flashing over time. We install wind-rated shingles and new metal flashing on every replacement.

What Staten Island customers say
“I highly recommend Alterphase Roofing! From start to finish, the experience was excellent. Their team was professional, knowledgeable, reliable, and attentive to every detail. They took the time to explain everything, answered all my questions, and made sure I felt comfortable throughout the process. It's not easy to find a company that truly cares about its customers and takes pride in its work. I really appreciate their honesty, quality of service, and professionalism. I would definitely recommend Alterphase Roofing to anyone looking for a trustworthy roofing company!”
“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…”
“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…”

Do you work in Arrochar?
Yes. Our office at 61 Appleby Ave is in the same ZIP code as Arrochar, 10305, so it's one of the closest neighborhoods we serve. We repair and replace roofs on houses, two-families and attached homes, and we answer emergency leak calls 24/7.
How much does a new roof cost in Arrochar?
Asphalt shingle roofs cost $3–$10 per sq ft installed and flat roofs $5–$16 per sq ft, the same as the rest of Staten Island. Most full shingle replacements land between $10,000 and $30,000. You get an exact written price after a free inspection.
Can you fix a leak where my roof meets my neighbor's?
Yes. On semi-attached and attached homes, the joint where the two roofs meet is the most common leak spot. We rebuild the flashing or membrane at the shared edge so water can't get between the buildings.
Do you repair flat roofs in Arrochar?
Yes. We repair and replace EPDM, TPO and modified bitumen flat roofs on attached homes, two-families, extensions and garages, and we fix the drainage when water sits on the roof.
How fast can you get to Arrochar for an emergency?
Arrochar is close to our office, so for an active leak we can usually get there the same day to stop the water with a tarp or temporary seal, then schedule the permanent repair.
