Frequently Asked Questions
Which shingle color is better for Florida's heat?
Lighter colors (weathered wood, driftwood, light gray) reflect more UV and reduce attic heat load by 10-15°F. Both brands offer Energy Star-rated cool roof options that qualify for some insurance credits.
Do impact-resistant shingles lower insurance in Florida?
Yes — Class 4 impact-resistant shingles from either brand can reduce your homeowners insurance wind premium by 20-30% in many Florida counties. Ask your insurer specifically about the discount before upgrading.
How long do shingles last on a Florida roof?
Manufacturer warranties of 30-50 years are based on northern climates. In Florida's UV, heat, and humidity, asphalt shingles typically need replacement after 15-22 years. Metal roofing lasts 40-70 years and is increasingly cost-competitive.
