Frequently asked questions
How long does a roof replacement take?
Most single-family asphalt shingle roofs are torn off and re-covered in one to three working days. Tile and metal roofs typically take three to seven days. The overall timeline, including permit issuance and final inspection, is usually two to six weeks.
Can I replace my own roof in Florida?
Florida allows an owner-builder permit on a home you own and occupy, but you must appear in person, sign the owner-builder disclosure statement, and take on liability for code compliance and inspections. Most insurers and mortgage lenders prefer a licensed roofing contractor.
Does homeowners insurance pay for a new roof?
Insurance generally covers sudden damage from a covered peril such as a windstorm, not wear-out from age. Florida carriers commonly require a roof inspection once the roof reaches 15 years, and may offer only actual cash value on older roofs.
Can you roof over existing shingles?
The Florida Building Code allows a limited number of roof coverings on a structure, but re-covering is restricted and many jurisdictions require a full tear-off when more than 25% of the roof area is being repaired or replaced. Verify with your local building department before assuming a re-cover is allowed.
