About AP Siding & Windows
The Siding Crew Your
Neighbors Already Use
AP Siding & Windows is a family-run exterior contractor working out of East Northport. We re-side, re-roof and replace windows on houses from Huntington to the Hamptons, and the people who show up on your property are our employees, not a crew we hired last week. We measure every job ourselves, give you a written price, and that price is the price.
Long Island houses are mostly capes, ranches, splits and colonials from the 50s through the 80s, and a lot of them are still wearing their original aluminum or a layer of vinyl somebody slapped over it. We've opened enough of those walls to know what's usually underneath. Every job gets a full tear-off, sheathing repair where it's needed, house wrap, proper flashing and siding installed to the manufacturer's spec, so the warranty actually holds.

Long Island, NY
Suffolk County's Siding, Window and Roofing Contractor
From the North Shore harbor towns through the Babylon and Islip south shore, east across Brookhaven to Riverhead and both forks, our crews cover all of Suffolk County. We're on the road in Huntington, Smithtown and Commack most days of the week, and we block out East End jobs so the crew stays on site from tear-off to final walkthrough.
Salt air off the Sound and the bays, nor'easters that push rain sideways, and winters that freeze and thaw every other week are hard on an exterior. That's why we pick siding with the wind rating and color warranty to match where your house sits, and why we won't quote off a photo. Someone comes out, measures, looks at the sheathing and trim, and writes it up.
Long Island Siding
Full replacement, insulated upgrades and repairs in vinyl, cedar shake, board and batten or fiber cement, matched to how your house is built and which way it faces.
Long Island Replacement Windows
Double-hung, casement, bay and bow, sliding, awning and custom shapes, measured to the opening and sealed into the wall before the siding goes on.
Long Island Roofing
Architectural shingle replacement, leak repair, flat roofs, ventilation and storm damage, with flashing and ice-and-water done right the first time.
What We Do
Siding, Windows and Roofing, Done by One Crew
Roofing
Tear-off and replacement with architectural shingles, flat roof systems for low-slope sections, leak tracking and repair, ridge and soffit ventilation, chimney flashing and skylights. Inspections if you're buying or selling.
Learn More →Siding
Vinyl for the budget, insulated vinyl for the heating bill, cedar shake and board and batten for the look, fiber cement when you want it to outlast you. Soffit, fascia and trim handled in the same visit.
Learn More →Windows
Energy-rated replacement windows in vinyl or fiberglass, installed as inserts or full-frame depending on what the old frame will support. Doing them with the siding saves you a second crew and a second flashing job.

Why Suffolk County Homeowners Call Us Back
Our own crews
No subcontractors. The installers on your house work for AP year-round, and the same foreman is there from day one to cleanup.
A written price after we measure
We don't quote from the curb. We measure, we look at the sheathing and trim, and the number on paper is what you pay.
Materials built for the shore
Wind-rated panels, fade-resistant color, and the hardware the manufacturer calls for, because warranties get voided by shortcuts.
A job site you can live in
Tear-off goes in the dumpster the same day, nails get swept with a magnet every afternoon, and we walk the property with you before we leave.
