Q: How long has Cornerstone Restoration been in business?
Cornerstone Restoration was established in 2005, and for nearly two decades we’ve built our reputation on quality craftsmanship, honest service, and long-term customer relationships.
Roofing & Storm Damage
Q: Do you handle both residential and commercial roofing?
Yes. We specialize in residential roofs such as asphalt, cedar, and DaVinci composite, and commercial flat roofs including TPO, Modified Bitumen, and Metal systems.
Q: How do I know if my roof needs to be replaced or just repaired?
We start with a thorough inspection — looking for hail, wind, or age-related wear. If the damage is widespread or the roof is near the end of its lifespan, we’ll recommend full replacement; otherwise, targeted repairs may suffice.
Q: Do you help with insurance claims for storm damage?
Absolutely. Our Haag-Certified Inspectors document hail and wind damage with photos, reports, and weather data to support your insurance claim. We’ll meet with your adjuster and guide you through the entire process.
