The last time I re-roofed, I went for full coverage with the shield, and honestly, it’s been a relief not worrying every time we get a big dump of snow or those weird warm-ups in January. It did cost more up front, but I figured it was cheaper than dealing with drywall repairs or mold down the line.
I get the peace of mind thing, but I’m not totally convinced full ice & water shield everywhere is always worth it—especially if you’ve got decent attic ventilation and keep up with snow removal. My place is a 1950s rambler, low pitch too, but after talking to a couple local roofers (and crawling around up there myself), I stuck with just the eaves and valleys. Haven’t had leaks yet, even after last year’s ice dam mess.
I do wonder if sometimes leaks are more about insulation and airflow than just underlayment. If warm air’s escaping into the attic, you’re gonna get those freeze-thaw cycles no matter what’s under the shingles. Not saying don’t go all out if it helps you sleep at night—just that sometimes the “minimum” can be enough if everything else is dialed in.
About those green underlayments: tried one on my garage roof as a test run. It was easy to work with, but can’t say yet how it’ll hold up through a few winters. Would love to hear if anyone’s seen them last 5+ years in our climate...
I’m right there with you on the “minimum can be enough” camp, especially if you’re not dealing with a ton of weird roof angles or cathedral ceilings. My inspector basically gave me a checklist: check insulation depth, make sure soffit vents aren’t blocked, and keep the snow rake handy. I did all that, then just put the ice & water shield at the eaves and around the chimney. Knock on wood, no leaks yet—even after that lovely February thaw where everything turned into a skating rink overnight.
As for those green underlayments, I slapped some on my shed roof last year (mostly because it was on sale). Still looks fine after one winter, but I’m not betting the house on it until it survives a few more freeze-thaw cycles.
I’ve always leaned toward “good enough” too, especially since my roof isn’t anything fancy—just a basic ranch, no valleys or crazy peaks. Haven’t had issues with leaks either, but I do wonder sometimes if I’m tempting fate by not going all-out on upgrades. Anyone here ever regret not adding extra ice & water shield or going with a beefier underlayment? I keep hearing mixed things about how much difference it really makes in the long run, especially with our freeze-thaw swings.
I get the “good enough” mindset, but after patching up more than a few “just fine” roofs that turned into swimming pools after a freak ice storm, I’m a little twitchy about skipping the beefier stuff. Freeze-thaw cycles are sneaky—one year you’re golden, next year you’re cursing at 2 a.m. with a bucket. On my last place, I cheaped out on underlayment and regretted it when an ice dam decided to test my living room ceiling. Not saying you need Fort Knox up there, but sometimes a little extra up front saves a lot of headaches (and drywall) later.
Man, you nailed it about freeze-thaw cycles being sneaky. I’ve seen so many “good enough” roofs turn into a disaster after just one weird storm. It’s wild how one winter can be totally chill, then the next you’re up there with a shovel and a prayer, hoping the ice dam doesn’t win. I get why folks want to save some cash up front, but honestly, I’ve never heard anyone say they regretted going a little beefier on the underlayment or flashing.
One thing I’ve noticed—especially in places where temps swing hard—is that even small shortcuts add up over time. Like, maybe you skip the ice & water shield on the eaves because “it hardly ever ices here,” but then you get that one freak storm and suddenly you’re pricing out new drywall and insulation. Happened to my neighbor last year. He thought he was safe with basic felt underlayment, but after that polar vortex rolled through, he had water dripping out of his light fixtures. Not fun.
I will say though, sometimes people go overboard and spend a fortune on stuff they don’t need for their area. Metal roofs are awesome for hail and snow, but if you’re in a milder climate, it might be overkill (plus noisy as heck in the rain). For me, it’s all about finding that sweet spot—don’t cheap out on the stuff that keeps water out (underlayment, flashing), but don’t let contractors upsell you on every bell and whistle either.
If you’re somewhere with wild weather swings or lots of trees dropping debris, I’d lean toward tougher materials and better waterproofing. Otherwise, just make sure whatever you pick is installed right—half the leaks I see are from rushed jobs or bad flashing around chimneys and vents.
Anyway, totally agree: spending a bit more now can save your sanity (and your ceiling) later.
