Key FAQs

  • Can I wait until next quarter to do repairs?

    Delaying repairs—especially with active leaks—can multiply costs and accelerate structural damage.

  • Do you offer preventative options after the repair?

    Yes, we recommend pairing repairs with annual maintenance to protect your investment.

  • Will this void my roof warranty?

    No—our repairs are done to spec and typically preserve manufacturer warranties, not void them.

Our home is 32 years old and needed a new roof. Karl was great and easy to work with through the estimation/quote process. The office was easy to work with for payments and scheduling. Anthony and his team were fun to work with while delivering on everything they said they'd do. Anthony kept the project running on schedule, worked around rainy days, and was a great resource for us to ensure our home was safe. The new roof looks excellent, new wood work around the roof turned out great, overall very happy.
