How Long Does Tarping Last

Roof Tarp Installation Process

Why are roofing quotes so different — one said $8,000, another said $22,000?

Quotes vary because contractors differ in materials, decking inspection scope, and whether they include proper underlayment and ice-barrier. The $8k quote is almost always using cheaper materials or skipping hidden damage assessment. Get at least 3 written quotes that itemize labor, materials, and warranty separately.

A storm chaser knocked on my door right after the hail storm. Should I use them?

Be very cautious. Storm chasers are often out-of-state crews that disappear after the job. They may use your insurance payout, do substandard work, and be unreachable when you have a leak 6 months later. Always hire a locally licensed contractor with a verifiable physical address and online reviews.

My roofer found rotted decking mid-project and now wants $3,000 more. Is this normal?

Hidden decking rot is a real discovery — most contracts legitimately allow for it. But get it in writing with photos BEFORE they replace it, and verify the per-sheet price is reasonable (typically $70–$120/sheet). Refuse to pay upgrades that weren't shown to you.

My roof was repaired 6 months ago and it's leaking again from the same spot. What can I do?

A quality repair should carry at least a 1–2 year workmanship warranty. Contact the contractor in writing (email creates a paper trail). If they're unresponsive, file a complaint with your state contractor licensing board. Document every leak with dated photos.

Will my homeowner's insurance cover roof replacement after hail or wind damage?

Most policies cover storm damage minus your deductible. Key steps: don't sign anything an insurance adjuster brings on-site without reading it, have your own contractor inspect BEFORE the adjuster if possible, and document all damage with photos and video the same day as the storm.

How long does a full roof replacement take, and will I need to be home?

Most residential roofs are replaced in 1–2 days for standard sizes. You don't need to be home but should be reachable. Make sure pets and vehicles are away from the work zone, and confirm the crew will use magnetic sweepers for nails in your yard before they leave.
