Frequently Asked Questions
Common questions about roof repair cost, insurance coverage, and repair-vs-replacement decisions.
Should I repair my roof or replace it?
If the damaged area is under ~30% of total roof surface and your roof is less than 15 years old, repair is usually the right call. For roofs over 20 years old or with multiple recurring leaks, the long-term math typically favors replacement, since repairs can run $500–$3,000 per incident and recur within 2–3 years on aging roofs.
Does homeowners insurance cover roof repair?
Insurance typically covers sudden damage from storms, hail, fallen trees, or fire. It usually does not cover wear-and-tear, age-related deterioration, or poor maintenance. File a claim with photos and a contractor's report; most insurers send an adjuster within 7–14 days. Note: filing increases your premium for 3–5 years, so for repairs under your deductible it's often cheaper to pay out of pocket.
How do I know if my roof has a leak?
Watch for water stains on ceilings, peeling paint near the roofline, visible drips during heavy rain, dark spots in the attic, granules in gutters, and a musty smell in upper rooms. A roofing contractor can run a hose test to pinpoint the entry point, since the leak's location inside often doesn't match where water enters above.
What's the difference between repair and replacement warranty coverage?
Repairs typically come with a 1–5 year workmanship warranty covering the specific patched area. Full replacements include a workmanship warranty (5–25 years depending on contractor) plus a manufacturer warranty on materials (20–50 years). Repairs do not extend the original roof's warranty; that started ticking when the roof was first installed.
Can I do a roof repair myself?
Minor work (replacing 1–3 shingles, sealing nail pops, clearing a vent boot) is feasible with the right safety gear and a low-pitch roof. Anything involving flashing, structural decking, or steep pitches should go to a licensed contractor; falls are the #1 cause of DIY roof injuries and improper flashing causes most repeat leaks.
How often should I have my roof inspected?
Once a year minimum, plus after any major storm or wind event. Many roofing companies offer free annual inspections. Catching small issues early (a missing shingle, a cracked vent boot) can prevent the $500 repair from becoming a $5,000 sheathing replacement.
