This is the question many homeowners forget to ask — until they get a flat tire or their child steps on a nail.
The magnetic nail sweep
Every professional roofing crew uses a rolling magnetic nail sweep at the end of every work day. This is non-negotiable. Ask specifically: "Do you use a magnetic nail sweep daily?" Watch their reaction. If they have to think about it — they don't.
What daily cleanup should include
- Rolling magnet sweep of all areas around the home including driveway and lawn
- Removal of all tear-off debris — not left on-site overnight unless in a sealed dumpster
- Inspection of gutters for nails and debris that fell during installation
- Final walkthrough with the homeowner before leaving each day
Final cleanup and walkthrough
When the job is complete, you should do a final walkthrough with the project manager before releasing the final payment. Walk the entire perimeter. Check the gutters. Look for debris in landscaping. Do not pay the final invoice until you're satisfied.
Any crew that leaves nails on your property overnight. One flat tire costs $150–300. One child's foot can cost far more.
