Roofs Built for Long Island Weather
Islip's tree-lined streets look great until a storm brings down branches onto the houses beneath them. Mature trees also drop leaves and debris that clog gutters and hold moisture on the roof, so Islip roofs need sound shingles, tight flashing and regular checks to stay watertight.
Promaster Maintenance Corp installs, repairs and replaces roofs for homes and businesses throughout Islip, a short drive along the South Shore from our West Babylon base. We also work in East Islip, Islip Terrace, Great River and Oakdale.

New Roof Installation and Replacement in Islip
A new roof is a major investment, and the installation matters as much as the material. Following the National Roofing Contractors Association's emphasis on underlayment, flashing and ventilation, every Islip installation includes:
- A full inspection of your existing roof and its structure
- Removal of the old roofing down to the decking
- Decking repairs where needed
- New underlayment, flashing and ventilation
- Installation of your chosen roofing material
Getting the layers under the shingles right is what stops leaks from appearing years down the line.
Roofing Materials for Every Style of Home
Islip's established neighborhoods include everything from modest capes to larger traditional homes. Promaster Maintenance Corp installs:

- Flat roofing systems:EPDM rubber, TPO and modified bitumen for low-slope sections

We explain the pros and cons of each so you can pick the right roof for your home and budget.

Flat roofs on Islip extensions, garages and commercial buildings drain slowly, so they need the right materials and regular attention. We provide:
- Flat roof replacement and new installation
- Flat roof repair for leaks, blisters and wear
- Commercial roof repair and maintenance
Leaves and debris left sitting on a flat roof can block drainage and cause ponding, so keeping it clear and catching seam damage early adds years to its life.
