Roof Leak Repair Timeline: What Should Happen in the First 24, 72, and 168 Hours
The realistic timeline for a roof leak repair — from emergency tarp to permanent fix — and what a slow contractor response actually costs you.
Every day a leak goes untreated multiplies interior damage cost. This is the timeline reputable contractors work to.
First 24 hours — stop the water
Emergency tarp or shrink-wrap over the affected area. Cost: $350–$900. Insurance pays under 'mitigation of damages' on almost every policy.
24–72 hours — diagnose
Roofer isolates the entry point with a hose test or drone thermal imaging. Interior ceiling opening if the leak path is unclear.
3–7 days — permanent repair
Weather permitting, permanent flashing/shingle/deck repair. Longer if custom flashing must be bent or matching shingles ordered.
What a slow response costs
Every 48 hours of active leak roughly doubles interior remediation cost. A $600 ceiling repair becomes a $2,400 drywall + insulation + mold treatment in one week.
Frequently Asked Questions
- Can I tarp it myself?
- Only if the pitch is under 6:12 and you have safe access. Anything steeper, call for emergency service — a fall costs more than any tarp.
- Does insurance pay for the tarp?
- Yes, mitigation is required by policy language. Keep the receipt and photos of the tarp in place.
