"Still, don't expect total silence; it mostly softens the sharper tapping sounds."
Yeah, that's been my experience too. Foam strips helped a bit with the tapping noise on my metal roof, especially during heavy rain. But honestly, after a while, I kinda got used to the sound—it became almost relaxing. Curious though, has anyone tried combining foam strips with something heavier like rubber or felt underneath? Wonder if that'd make a noticeable difference or just be overkill...
I've seen folks try rubber mats under metal roofing before, and honestly, it does help a bit more than foam alone. Had a client once who was super sensitive to noise—he layered felt under the foam strips, and it noticeably dulled the tapping. Didn't eliminate it completely, but made it more muffled and less sharp. Might be worth experimenting with a small section first though... rubber can get pricey fast.

Can confirm this helps. Had a similar issue after a hailstorm repair. Client couldn't stand the noise afterward, so we tried rubber mats first—worked okay, but pricey as mentioned. Ended up using felt strips under foam instead. Cheaper and pretty effective at softening that sharp tapping sound. Might depend on roof pitch and material though...
Did the same thing on my porch roof last summer after a heavy rain made it sound like a drumline out there. Felt strips definitely cut down the noise, but I noticed it also depends on how tight you secure everything. Too loose and you still get some rattling, too tight and it seems to transfer vibrations more. Took me a couple tries to find that sweet spot...but worth the effort for sure.
Had a similar experience with my shed roof—metal edging was rattling like crazy during storms. Tried felt strips too, and you're right about the tension thing. Took me forever to dial it in. Eventually went with some rubber washers under the screws, which seemed to dampen vibrations better. Curious if anyone else tried different materials besides felt? Felt worked okay, but I'm always looking for something quieter or more durable...
