How it works

How a roof keeps water out.

A roof is a system of layers, not just shingles. Each one has a job, and a leak usually means one of them has failed.

Some roofs can be patched for years. Others are past the point where repairs make sense. It’s time to think about replacing your roof when you see:

Leaks in more than one place, or leaks that keep coming back after repairs
Shingles that are curling, cracked or missing across large areas, not just one spot
Heavy granule loss: bald patches on the shingles and grit piling up in the gutters
A sagging roofline, or a deck that feels soft underfoot
Daylight, damp insulation or dark staining on the underside of the roof deck
An asphalt shingle roof that’s around 20 years old or more

Not sure? A roof inspection will tell you. If a roof repair will buy you real time, we’ll say so.

Size and pitch. Bigger and steeper roofs take more material and more labor.
Material. The shingle line and style you choose change the cost.

What happens during a roof replacement

Protect the propertyWe cover plantings, protect the house and set up so debris goes where it should.
Tear-offThe old shingles, underlayment and worn flashing come off down to the deck.
Deck repairWe check the deck and replace any soft or rotted wood.
Leak barrier and underlaymentSelf-sealing leak barrier at the eaves and in the valleys, underlayment over the rest.
Flashing, drip edge and ventilationNew metal at the edges and around chimneys, walls and skylights, with soffit and ridge ventilation balanced for the attic.
New shinglesInstalled to the manufacturer’s instructions and finished with ridge caps.
Clean-upWe clean up completely and sweep for nails before we leave.

Replacing the roof is also the ideal time to add or replace a skylight or redo the chimney flashing, since everything gets flashed together with the new roof.

Getting ready for replacement day

A roof replacement is loud and busy, but there isn’t much you need to do. A little preparation helps it go smoothly:

Move cars out of the driveway and garage so the crew has room for the dumpster and materials.
Cover or move anything stored in the attic. Tear-off shakes loose dust and old nails.
Take down pictures and fragile items on top-floor walls and shelves.
Keep pets and children inside and away from the work area.
Let your neighbors know. It’s a courtesy they’ll appreciate.

We’ll tell you the start date, what to expect each day and when the dumpster will be picked up.

Roof replacement FAQ

Common questions.

Still not sure?

Call 631-965-0881 any time. We'll tell you straight whether it's a repair or a replacement.

How do I know if I need a roof repair or a full replacement?

Missing or damaged shingles, leaks that keep coming back, shingle granules in the gutters and a sagging roofline are the main warning signs. A small, isolated problem can usually be repaired; widespread wear on an older roof usually means replacement is the better investment.

How long does a roof last on Long Island?

Most roofs here last about 20 to 30 years, depending on the material. Asphalt shingle roofs are typically expected to last around 20 years, while metal roofs can last up to 50.

What warranty comes with a roof replacement?

Every new roof we install comes with a 10-year labor warranty plus a lifetime manufacturer warranty. We go over what each one covers before work starts.
