Temporary Roof Repair Options After Storm Damage
The goal of temporary repair is not to fix the roof, it is to stop water from entering the home until the permanent repair happens. Every temporary method has a limited lifespan and should be monitored regularly. Using the right temporary fix for the type of damage prevents the cascading interior damage that turns a manageable roof repair into a major restoration project.
Tarping for Large Exposed Areas
When an entire section of roof is missing shingles, decking is exposed, or a tree has created a large breach, a heavy-duty polyethylene tarp is the only practical temporary solution. Professional tarping costs $300 to $1,000 and provides 30 to 90 days of protection depending on the tarp quality and weather conditions.
The tarp should be at least 6 mil thick, extend four feet past the damaged area on all sides, and be secured with 2x4 boards nailed through the shingles into the deck or weighted with sandbags. The uphill edge must be sealed tightly to prevent water from flowing under the tarp, and the tarp should slope consistently downhill to shed water rather than pool it.
For DIY tarping on a single-story, low-pitch roof, materials cost $50 to $150 at any hardware store. Never attempt to tarp a steep or multi-story roof without professional equipment and training.
Roofing Cement for Small Cracks and Lifted Shingles
Roofing cement (also called roof sealant or plastic cement) is a thick, tar-based adhesive that seals small cracks, re-adheres lifted shingle tabs, and fills gaps around flashing and penetrations. A tube costs $5 to $15 and covers multiple small repair points.
To re-seal a lifted shingle, apply a generous bead of roofing cement under the lifted edge and press it firmly into place. For cracked shingles, apply cement over the crack and smooth it flat. For small gaps around flashing, fill the gap with cement and tool it smooth against both surfaces.
Roofing cement is effective for three to twelve months depending on UV exposure and temperature. It becomes brittle in cold weather and soft in extreme heat, so it is truly temporary. Do not use it as a permanent solution for any damage point.
Self-Adhesive Roofing Tape for Seams and Flashing
Roofing repair tape (sometimes called peel-and-stick membrane or butyl tape) is a flexible, waterproof tape that adheres to most roofing surfaces. It works well for temporarily sealing split shingles, cracked vent boots, separated flashing seams, and small tears in flat roof membranes. A roll costs $15 to $40 and covers a significant amount of linear repair.
Clean and dry the surface before applying the tape. Press it firmly into full contact with the roofing material, smoothing out any air bubbles. The adhesive bonds best in temperatures above 45 degrees Fahrenheit. In cold weather, warm the tape with a heat gun or hair dryer before application to activate the adhesive.
High-quality butyl-based tapes provide six months to a year of protection. They are particularly useful for vent boot repairs, where a strip of tape wrapped around a cracked rubber collar creates a reliable temporary seal.
Emergency Patch Kits for Punctures
Roof punctures from debris impact can be temporarily sealed with a piece of sheet metal or plywood placed over the hole and sealed around the edges with roofing cement or tape. For small punctures under a few inches, a piece of flashing material or even a heavy-duty aluminum baking pan can serve as the patch material.
Slide the patch under the surrounding shingles on the uphill side so water flows over the patch rather than under it. Seal all edges with roofing cement and, if possible, nail the corners through the shingle layer into the decking. This creates a layered seal that can withstand rain and moderate wind for several weeks.
For flat roofs, self-adhesive EPDM or TPO patch kits designed for the specific membrane type provide the best temporary repair. These kits cost $20 to $50 and include the patch material, primer, and adhesive for a reliable seal.
Document Everything for Insurance
Photograph the damage before you apply any temporary repair, so the original condition is on record. Then photograph the temporary repair after it is in place. Keep receipts for all materials purchased and any professional services hired. This documentation serves two purposes: it proves you took reasonable steps to mitigate further damage (which your policy requires), and it establishes reimbursable expenses that are part of your overall claim.
When Not to Attempt Temporary Repairs Yourself
Leave temporary repairs to professionals when the roof is steep, multi-story, or the damage area requires walking on a potentially weakened deck. Also avoid DIY temporary repairs when structural damage is visible (sagging roofline, displaced rafters) or when the damage is near energized electrical equipment on the roof.
The cost of professional temporary repair is modest compared to the medical costs and lost wages from a fall injury. Your insurance covers professional tarping and emergency repair costs, so there is no financial advantage to taking unnecessary risks.
How Long Temporary Repairs Last
| Repair Method | Typical Lifespan | Material Cost |
|---|---|---|
| Heavy-duty tarp (professionally installed) | 30 - 90 days | $50 - $150 (materials) / $300 - $1,000 (installed) |
| Roofing cement | 3 - 12 months | $5 - $15 per tube |
| Self-adhesive roofing tape | 6 - 12 months | $15 - $40 per roll |
| Emergency patch (metal/plywood) | 2 - 8 weeks | $10 - $30 |
| Membrane patch kit | 3 - 12 months | $20 - $50 |
Match the temporary repair method to the type and size of damage, document everything before and after, and treat all temporary fixes as a bridge to permanent repair rather than a long-term solution. The cost of temporary repairs is typically covered by insurance and prevents the far more expensive secondary damage that unprotected breaches cause.
