## Answer

The most reliable temporary roof leak patch materials are 6–10 mil poly tarps anchored with furring strips, self-adhering ice-and-water shield membrane pressed over dry shingles, and asphalt roofing cement in a caulk tube for small punctures — all are short-term measures meant to hold for weeks, not months.

## Rank order of what works

Per NRCA and manufacturer guidance, the best short-term fix is a properly anchored tarp because it doesn't rely on adhesion to a wet or dirty surface. Ice-and-water shield (self-adhering modified bitumen) is a strong second when the surface is dry and clean. Asphalt roofing cement fills small punctures but fails on wet or dusty surfaces.

Silicone caulk, house paint, and generic sealants are not roofing-grade and commonly fail within a single rainfall.
