Roofs Built for Long Island Weather
Shirley sits on the South Shore close to the bay and the bridge out to Smith Point, and when Atlantic storms come through, roofs here feel it first. Strong gusts lift shingles, wind-driven rain gets under flashing and damp sea air works on every fastener.
Promaster Maintenance Corp installs, repairs and replaces roofs for homes and businesses across Shirley. We also work in Mastic, Mastic Beach, Ridge and Yaphank.

New Roof Installation and Replacement in Shirley
A new roof near the coast has to be built to hold on in high winds. The National Roofing Contractors Association stresses underlayment, flashing and ventilation, and every Shirley installation includes:
- A full inspection of the existing roof and structure
- Removal of the old roofing down to the decking
- New underlayment and flashing to keep wind-driven rain out
- Decking repairs where needed
- Proper ventilation and installation of your chosen roofing material
Sound underlayment and well-sealed flashing are your roof's second line of defense when a storm lifts the shingles.
Roofing Materials for Every Style of Home
For coastal homes in Shirley, the right material depends on style, budget and exposure to wind. We install:
- Architectural asphalt shingles:the most popular choice, with options such as Owens Corning, CertainTeed Landmark and GAF Timberline
- Cedar shakes:a natural look that suits many coastal homes
- Metal roofing:durable, lightweight and energy efficient
- Flat roofing systems:EPDM rubber, TPO and modified bitumen for low-slope roofs
- Slate:exceptionally long lasting
We talk you through the pros and cons of each so you can choose what will stand up best on your home.
