Roofs Built for Long Island Weather
Mid-Island winters in Ronkonkoma bring snow, ice and repeated freezing and thawing, and roofs here have to shed all of it. Poor ventilation lets heat build up in the attic, which can melt snow on the roof and refreeze it at the edges, while worn shingles and flashing let meltwater in.
Promaster Maintenance Corp installs, repairs and replaces roofs for homes and businesses across Ronkonkoma, from the streets around the lake to the neighborhoods near the station. We also work in Lake Grove, Holbrook, Bohemia and Centereach.

New Roof Installation and Replacement in Ronkonkoma
A Ronkonkoma roof needs to be built for winter as well as summer. The National Roofing Contractors Association stresses underlayment, flashing and ventilation, and every installation we carry out includes:
- A full inspection of your existing roof and structure
- Removal of the old roofing down to the decking
- Decking repairs where needed
- New underlayment, flashing and proper attic ventilation
- Installation of your chosen roofing material
Good ventilation helps keep the attic cool and dry, which protects the roof through every season.
Roofing Materials for Every Style of Home
Ronkonkoma's mix of ranches, capes and colonials suits several roofing options. Promaster Maintenance Corp installs:
- Architectural asphalt shingles:the most popular choice, with Owens Corning, CertainTeed Landmark and GAF Timberline among the options
- Metal roofing:durable, lightweight and quick to shed snow
- Flat roofing systems:EPDM rubber, TPO and modified bitumen for low-slope roofs
- Slate:exceptionally long lasting
- Cedar shakes:a natural, traditional look
We go through the pros and cons of each to help you choose.
