Has anyone tried those liquid-applied membranes at the edges? Wondering if they’re worth the extra cost or just overkill for most situations.
I’ve seen a few roofs where the liquid stuff was used at the eaves, mostly on low-slope or flat roofs. It definitely sealed things up tight, but I’m not convinced it’s necessary for steeper pitches unless you’ve got chronic water intrusion. Did you notice any difference in how the drip edge handled runoff after adding the root barrier? Sometimes those little changes can mess with drainage patterns.
I’ve had a few contractors try to upsell me on those liquid membranes, but honestly, I’m still not sold unless you’re dealing with a real problem area. On my last place (old farmhouse, 5/12 pitch), I just stuck with regular ice and water shield at the edges and never had issues—even through some nasty spring storms. The only time I saw weird runoff was after adding a green roof mat; suddenly, water would pool where it never did before. Sometimes “upgrades” make things more complicated than they need to be...
That’s a fair point—liquid membranes aren’t always necessary, especially on a moderate pitch like 5/12 unless you’re dealing with persistent leaks or really tricky details. I’ve seen them help in spots where ice dams are chronic or there’s a lot of complex flashing, but for most jobs, standard ice and water shield does the trick. Interesting about the green roof mat causing pooling... sometimes those add-ons change water flow in ways you don’t expect. Always worth weighing the pros and cons before jumping on every “upgrade.”
I get what you’re saying about ice and water shield usually being enough, but I’ve run into a few jobs where it just didn’t cut it—especially on older homes with weird valleys or low spots. Had one client swear up and down they had “everything done right,” but water still found its way in after a big thaw. Ended up using a liquid membrane just in the trouble area, and it finally solved the mystery leak. Sometimes those extra steps feel like overkill, but they can save a ton of headaches if you’ve got a tricky roof or unpredictable weather.
Liquid membrane to the rescue... been there, done that. Sometimes I think roofs are just out to mess with us, especially on those old houses where nothing’s square and you find surprises under every shingle. I’ve had to get creative a few times—once even used peel-and-stick in spots the architect swore would “never see water.” Guess who was wrong after that first spring melt? Out of curiosity, have you ever had to rip up a “perfectly good” section just to chase down a sneaky leak, or do you usually spot the culprit right away?
