Yeah, I hear you on that. Synthetic’s a bit tougher than felt in my experience—less likely to tear if the wind kicks up again before you get new shingles on. But once those nails go in, you’re always gonna have tiny paths for water, no matter what material you use. Had a job last year where synthetic bought us about two weeks after a hailstorm, but we still had to hustle to avoid ceiling stains. Like you said, it’s just buying time—nothing beats having the shingles actually there doing their job.

Yeah, I get where you’re coming from. That bit about “tiny paths for water, no matter what material you use” rings true. I went with synthetic underlayment last fall because the roofer swore it’d hold up better if we got sudden rain before the shingles were on. Honestly, it did seem tougher than the old felt rolls we found in the shed, but I was still nervous every time a storm rolled through before they finished.
Here’s what I noticed:
1. Even with the synthetic, once those nails go in, there’s always a risk. Maybe less tearing, but water still finds a way if you wait too long.
2. The real peace of mind comes when the shingles are actually up—everything else just feels temporary.
3. If you’re stuck waiting (like insurance dragging their feet), maybe check those nail spots after storms for seepage. I caught a tiny leak that way and patched it before it got to the ceiling.
I wouldn’t say synthetic is a miracle fix, but in my case it bought me some time—just not as much as I hoped. Still beats bare wood though...
I had a similar situation last winter—insurance took forever to approve the claim, and the roofers could only get the synthetic underlayment on before a big storm hit. I was surprised how well it held up, but I still found a couple of damp spots around the nail holes after a heavy rain. Maybe it’s just my old roof deck, but I agree, nothing feels secure until those shingles are nailed down. The waiting game with insurance is honestly more stressful than the actual repairs...
That’s pretty much par for the course with insurance—lots of waiting, not much communication. I’ve seen a lot of jobs where the underlayment sits exposed for weeks because of delays, and honestly, synthetic does a decent job short-term. But you’re right, it’s not a real roof. Water will find its way in, especially around fasteners or seams, and if your decking’s older or has any soft spots, it just makes things worse.
One thing I always tell folks: after a big rain, check the attic for any signs of moisture, not just the ceiling. Sometimes you’ll catch a leak early before it turns into a bigger headache. Also, if you’re stuck waiting, make sure the roofers come back to check the underlayment—wind can lift edges or pull nails, and you don’t want to find out after the next storm.
Insurance dragging their feet is the worst part, no question. The repairs themselves are usually straightforward once you get the green light. Just keep an eye on things until those shingles are finally down.
Waiting for insurance is like watching paint dry, except you’re worried about leaks the whole time. I’ve seen underlayment hold up fine in the short run, but like you said, it’s not foolproof—especially with older decking. I always tell folks to stick their head up in the attic after a storm, even if it feels silly. Found a damp rafter once that would’ve turned into a nightmare if I’d waited. Wind’s no joke either... had synthetic peel back on me during a surprise gust last spring. Just gotta babysit things until the real roof finally goes on.
