What to expect when you hire us, step by step
Hiring a roofer shouldn't feel like a gamble. Here's exactly how a job goes with Alter Phase Roofing Contracting, from your first call to the warranty in your hand.
Every Alter Phase Roofing Contracting job follows four steps: a free on-site inspection with photos; a written, itemized estimate, usually within 24 hours; the work done by our own crew with the owner involved; and a final walkthrough with written warranties of up to 50 years on materials and 25 years on workmanship.

Step 1: Free inspection
You call or fill in the estimate form. We set a time that works for you and come out to look at the roof. Not from the driveway, but up on the roof. We check the surface, flashing, vents, gutters and, when we can, the attic, and scan for hidden moisture with an infrared (thermal imaging) camera. Then we show you photos of what we found.
Step 2: Written estimate
Within about 24 hours, you get a written, itemized estimate: what's wrong, what we recommend, the materials we'll use, and the price, including cleanup, disposal and permits when they're needed. When it's close between repair and replacement, you get both prices. No pressure to decide.
Step 3: The work
We schedule a start date and keep you updated if weather moves it. On the day, we protect your property: tarps over landscaping, care around neighbors and the sidewalk. Our own crew does the work, and owner Marke is part of every job. For replacements, rotted decking is replaced and new flashing goes in; nothing important gets reused to save time. We clean up every day.
Step 4: Walkthrough and warranty
When we're done, we walk the job with you, show you photos, and answer every question. You get your warranties in writing: up to 50 years from the manufacturer on materials and up to 25 years from us on workmanship. Then we're one phone call away for as long as you own the house.
Our commitment: 100% satisfaction
We want to be the roofing company you recommend to your family and neighbors. That only happens if you're genuinely happy with the work, so if something isn't right, we make it right.

What Staten Island homeowners 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…”
