Roofing questions in Dallas.
Ask your local teamWhich Mammoth office serves Dallas?
Serving Dallas from our Garland office.
What does the Roof Grade cost?
Nothing. The 32-point Hunter-Gatherer inspection is free, and the written report is yours to keep whether or not you hire Mammoth. It is also your estimate: the same visit gives you a written price for any work it finds, repair or full replacement.
What does the roof inspection include?
The attic first, then every slope: 32 points in three sections (roof surface, attic and ventilation, water flow), 75–150 time-stamped photos, measurements and a Roof Grade with a plain-English verdict: leave it, repair it or replace it.
How often should a roof be inspected?
Once a year, and after any hail or high-wind event. Older roofs and heavily treed lots benefit from twice. Between visits, watch for curled or cracked shingles, granules piling up in the gutters and new stains on a ceiling.
What about permits and HOA approval in Dallas?
Your municipality and neighborhood can have different requirements. We confirm the permit and material-approval requirements for your address before work begins.
Can a roofer waive my deductible in Texas?
No. Texas law prohibits a contractor from offering to waive, rebate or absorb a property-insurance deductible. Your insurer determines the coverage under your policy.Texas Department of Insurance
How long does an insurance claim take?
Timing depends on your policy, the information the insurer needs and any applicable catastrophe extension. Ask your insurer about your claim deadline and use the Texas Department of Insurance’s guide to understand the process.Texas claims process guide
