Temporary Roof Tarp: Cost, Coverage, and When It Is Enough
An emergency tarp is the fastest way to stop water intrusion after storm damage. Here is what it costs, when it is sufficient, and whether insurance covers it.
What a tarp actually does
A tarp is a temporary barrier — typically heavy-duty polyethylene — stretched over the damaged area and secured with battens or sandbags. It stops water intrusion but does not fix the underlying damage.
Typical cost
- Small residential roof: $300 – $500
- Medium: $500 – $800
- Large or steep roof: $800 – $1,500
- Emergency after-hours callout: $200 – $500 surcharge
Is it covered by insurance?
In most cases, yes — as a "mitigation" expense. Insurers are usually required to reimburse reasonable costs to prevent further damage. Save the receipt and photograph the tarp in place.
When a tarp is enough — and when it is not
Usually enough for: short-term protection (days to a few weeks), a single damaged area, or while waiting for adjuster review.
Not enough for: structural damage, sagging decking, large missing sections, or any active leak that continues after tarping. These require immediate repair or replacement.
DIY vs. professional
Professionals have the equipment, safety gear, and insurance to work on a roof. Falls are the leading cause of home-injury deaths in the U.S. — do not climb a wet or damaged roof, ever.
Frequently asked questions
How long can a tarp stay on?
Two to four weeks is typical. Longer than a month, and the tarp itself may damage the roof further or hide developing problems.
Will insurance pay for the tarp?
Usually yes, if the damage is covered. Save the receipt and the contractor's invoice.
Is a tarp considered a permanent repair?
No. It is a mitigation measure. The insurer will separately evaluate the underlying damage.
Can I tarp my own roof?
Only if you can do it safely from the ground or with proper equipment and a second person. If you have any doubt, call a professional.
