We are fans of Tristate. We had windows replaced by them last year and this year they replaced another window, a patio door and our siding. There were a few complications Tristate came across with the siding manufacturer, but they overcame their obstacles and actually provided us a more superior siding product.

Find answers to common questions about roof installations, repairs, maintenance, and service areas in Piscataway.
Protect the area inside your home and schedule a roof inspection as soon as possible. Avoid climbing onto a wet roof, as the visible ceiling leak may not be directly below the actual roof damage.
Yes. Missing or wind-damaged shingles can expose the roofing system to water. A roofer should inspect the affected area before the next major rain or storm.
Roof leaks can come from damaged flashing, vents, pipe boots, valleys, or small shingle defects that are difficult to see from the ground. An inspection can trace the actual moisture source.
It is better to inspect it promptly. Even a small leak can allow moisture into insulation, decking, drywall, or framing and potentially turn a minor repair into a larger project.
Document visible damage safely and arrange a professional inspection. If you may file a claim, notify your insurer promptly and follow your policy requirements before authorizing major permanent repairs.
Often, yes. Localized shingle damage may be repairable if the surrounding roof and decking remain in good condition. The extent, location, and age of the existing roofing system determine whether a targeted repair is practical.
Repeated leaks near roof penetrations often involve flashing, pipe boots, seals, or nearby shingles. Simply applying more sealant may not solve the underlying problem, so the surrounding roofing system should be inspected.
Damaged roof decking may need to be replaced before the new roofing system is installed. Ask your contractor beforehand how unexpected decking repairs will be documented, approved, and priced.
Roofing schedules may need to change when rain or severe weather could expose the roof deck or interfere with safe installation. Your contractor should explain how unfinished areas will be protected if weather changes unexpectedly.
Look for the roofing materials, tear-off scope, underlayment, flashing, ventilation, cleanup, disposal, payment terms, warranty details, and procedures for unexpected repairs. Compare the scope of work, not just the final price.
Home improvement contractor businesses performing roofing work in New Jersey generally must maintain state registration. Homeowners can verify a contractor’s current registration through the New Jersey Division of Consumer Affairs before signing a contract.
Permit requirements can depend on the exact scope of work, especially if structural changes or related work are involved. Your contractor should confirm applicable requirements with Piscataway’s construction officials before starting the project.
Ask about registration and insurance, materials, ventilation, flashing, cleanup, unexpected wood repairs, project scheduling, payment terms, and both workmanship and manufacturer warranties. Clear written answers make roofing estimates much easier to compare.
