Roofing in Todt Hill: what we see on these homes

Todt Hill is the highest natural point in New York City and one of Staten Island's most exclusive neighborhoods, known for large homes on quiet streets and private cul-de-sacs. Part of the hill is in the Staten Island Greenbelt, and Moravian Cemetery sits at its base on Richmond Road. The homes, and their roofs, are bigger and more complex than almost anywhere else on the island.

Steep, complex roofs

Large custom homes often have steep pitches, many valleys, dormers, turrets and several chimneys. Every one of those joints needs proper flashing. We plan the job around safe access on steep slopes and photograph every detail, before and after.

Premium shingles

Many Todt Hill homeowners want a roof that matches the house. As a GAF Master Elite® contractor we install GAF architectural and designer shingles, which give the look of slate or wood shake with the coverage of a GAF roofing system warranty.

Heavy tree cover

Wooded lots near the Greenbelt drop leaves and needles into valleys and gutters, and shade keeps parts of the roof damp. We clear the valleys and gutters on every job and recommend gutter guards where the trees are heaviest.

What a roof costs in Todt Hill

Todt Hill uses the same Staten Island prices as the rest of the island. Most roof repairs cost $300–$1,200, and asphalt shingle roofs cost $3–$10 per sq ft installed, so most full replacements on Staten Island land between $10,000 and $30,000. Large, steep Todt Hill roofs usually sit at the upper end. Your exact price depends on the size and pitch of the roof, how many layers come off and the condition of the deck.

“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…”

“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.

My house now…”

Roofing: common questions

Do you work in Todt Hill?

Yes. We repair and replace roofs on Todt Hill homes of every size, including large custom homes on private roads and cul-de-sacs, and we answer emergency leak calls 24/7.

How much does a new roof cost on a Todt Hill home?

Asphalt shingle roofs cost $3–$10 per sq ft installed on Staten Island. Todt Hill homes are often larger, steeper and more complex, with more valleys, dormers and flashing, so they usually sit at the upper end of that range. You get an exact, itemized written price after a free inspection.

Can you install designer shingles?

Yes. As a GAF Master Elite® contractor we install GAF's architectural and designer shingle lines, which give the look of slate or wood shake with the warranty of a GAF roofing system.

Why do steep, complex roofs leak?

Every valley, dormer, chimney and wall joint is a place where water collects or changes direction. Leaks on complex roofs almost always start at one of those joints, so we flash each one with new metal and check the valleys on every visit.

Do the trees on Todt Hill affect my roof?

Yes. Much of Todt Hill is wooded, and leaves and needles collect in valleys and gutters, while shade keeps parts of the roof damp. We clear the valleys and gutters on every job, and gutter guards help on heavily wooded lots.
