Just finished sealing up my roof deck last weekend and thought I'd share how I tackled it. Honestly, it was a bit of a pain at first because I wasn't sure where to start. First off, I stripped off the old shingles and cleaned everything down to the plywood. Then I checked for any soft spots or rot—luckily, nothing major there.
Next step was taping all the seams with a good quality roofing tape. After that, I applied a peel-and-stick membrane over the entire deck surface. This stuff is pretty sticky, so heads up—once it's down, it's down for good, haha. Took some patience to avoid wrinkles and bubbles, but got there eventually. Finally, I put down new shingles on top.
The whole thing took me about two weekends (and a few beers), but now I'm feeling pretty confident it'll hold up against storms and leaks.
I'm curious though if anyone here has done something similar and maybe found an easier or quicker method? Or maybe there's some trick or product you swear by that makes this whole process less of a headache...
Sounds like you did a solid job. I've tackled a few roof decks myself, and honestly, the peel-and-stick membrane is probably your best bet for durability. One thing I've found helpful though is using a weighted roller to smooth it out—makes dealing with bubbles and wrinkles way easier. Curious if you considered any liquid-applied membranes instead? I've heard mixed things, but some folks swear they're quicker to apply...
I've experimented a bit with liquid-applied membranes, and while they're definitely quicker to put down initially, the prep work can be pretty demanding. Surface cleanliness and temperature conditions have to be spot-on or you'll end up with adhesion issues down the line. Peel-and-stick membranes, especially when paired with a weighted roller like you mentioned, offer more consistent results in my experience—particularly if you're aiming for longevity. Liquid membranes aren't bad per se, but they're less forgiving if conditions aren't ideal...
I've mostly dealt with peel-and-stick membranes myself and they've been pretty reliable, but I've seen liquid membranes used on a few jobs. Seems like the prep work is really key, and I've noticed some guys really struggle if the weather isn't cooperating. Do you think the hassle of waiting for ideal conditions makes liquid membranes less practical overall? Or is there a trick to managing temperature and humidity that makes it worth the effort? Curious if anyone's found a workaround or maybe had success applying it in less-than-perfect conditions without running into adhesion headaches later on...
I've had mixed results with liquid membranes myself—when conditions are perfect, they're fantastic, but honestly, the weather rarely cooperates. Peel-and-stick has been my go-to just because it's less finicky and saves me from constantly checking forecasts.
