Tearing off a roof creates a localized debris storm of heavy asphalt, jagged fiberglass, and 10,000+ rusted nails. Quality contractors mitigate this by charging a “Property Protection Fee” (typically $250 to $600). This covers the labor and materials to build plywood A-frames over your HVAC units, deploy heavy canvas tarps over landscaping, perform guaranteed magnetic nail sweeps, and rent the OSHA-mandated portable toilet for the crew.
Homeowners reviewing a roofing estimate often balk at line items labeled “Site Prep,” “Protection,” or “Sanitation.” A common reaction is: “Why am I paying extra for you to not destroy my house?”
The reality is that a residential property is a highly vulnerable construction zone. Falling debris obeys gravity, and a 5-pound chunk of old shingles dropping 20 feet will instantly shatter an AC fan grate or crush expensive landscaping. If a contractor’s bid is missing a protection fee, it means they are skipping the setup phase and exposing your property to massive liability.
Property Risk & The Cost of Protection
In Xactimate, structural protection is billed under the PROT (Protection) code. Professional crews allocate the first 1 to 2 hours of the day strictly to deploying defensive measures around the perimeter of the home. Here is what you are actually paying for:
| Vulnerable Asset | Required Protection Protocol | Estimated Cost |
|---|---|---|
| HVAC / AC Condensers | Building a rigid 3/4″ CDX plywood “A-Frame” over the unit. Tarps will not stop a heavy falling shingle from bending the fan blades. | $50 – $75 per unit |
| Swimming Pools | Deployment of specialized micro-mesh pool covers. Granules and fiberglass dust from old shingles will ruin standard pool pump filters if they enter the water. | $100 – $150 |
| Garage Doors / Windows | Hanging heavy-duty canvas drop cloths from the gutters down to the ground to deflect falling debris away from fragile glass and painted metal. | $75 – $100 |
| Garden Beds / Shrubs | Tent-style tarping using stakes to create a slide, guiding debris over delicate bushes rather than crushing them. | $50 – $100 |

One of the most contested line items on a roofing bid is the $150 to $200 charge for a Portable Toilet. Homeowners frequently say, “The crew can just use my guest bathroom, take the fee off.” A reputable contractor will refuse this.
- The Federal Law: Under OSHA Standard 1926.51(c)(1), employers are legally mandated to provide dedicated toilet facilities at construction sites. Relying on a homeowner’s permission (which can be revoked at any time) does not satisfy this federal labor requirement.
- Liability & Privacy: Allowing a crew of 6 roofers covered in asphalt dust, fiberglass, and sweat to walk through your home creates a massive liability for property damage, theft accusations, and privacy violations.
- The Verdict: Paying the $150 sanitation fee is the cheapest insurance policy you can buy to maintain the boundary between your private sanctuary and a chaotic construction site.
The Magnetic Sweep Guarantee
A single roof replacement involves stripping and replacing roughly 10,000 to 15,000 nails. Statistically, hundreds of these will bounce off tarps and land in your grass, garden beds, and driveway.
Cleaning this up requires specialized equipment. Professional contractors utilize high-powered, 50-pound pull magnetic sweepers. They must walk your property in a grid pattern multiple times. Some premium contractors will run the magnet once during the initial cleanup, and a second time the following morning, as morning dew often reveals nails hidden deep in the turf. This meticulous process adds labor hours to the end of the job, which is factored into the site protection and prep cost.

What happens if the roofers break my AC unit or window?
If you hired a licensed, bonded, and insured contractor, their General Liability Insurance policy will cover the cost of repairing or replacing the damaged AC unit, window, or landscaping. Always verify a contractor’s insurance certificate before allowing them to begin demolition.
Should I pay extra for a portable toilet?
Yes. It is legally required under OSHA regulations for construction sites, and it prevents dirty crews from tracking hazardous fiberglass and asphalt dust through the interior of your home.
