Frequently Asked Questions

  • How do I know if my roof needs to be repaired or fully replaced?

    Signs like missing shingles, leaks, sagging areas, or excessive granule loss often indicate roof issues. We can inspect your roof and explain whether a repair or full replacement is the most cost-effective long-term solution.

  • What roofing materials hold up best in Vermont’s climate?

    Architectural asphalt shingles are the most popular due to their durability, insulation value, and resistance to snow and ice. We can also discuss underlayment and ventilation upgrades that improve winter performance.

  • How long does a typical roofing project take?

    Most residential roofing projects take one to three days depending on the size of the home, weather conditions, and material type. We provide clear timelines before work begins so there are no surprises.

  • What are the benefits of replacing old windows?

    New windows improve energy efficiency, reduce drafts, lower heating costs, and enhance your home’s appearance. They also provide better noise reduction and long-term durability.
