I’ve been helping out on a few jobs this winter and honestly, the freeze/thaw cycle here is brutal. I totally agree about skipping regular felt—my boss switched to synthetic underlayment last year and it’s holding up way better. It’s a bit pricier, but when you’re tearing off old roofs and see how felt just disintegrates after a few seasons, it’s hard to go back.
I’m curious if anyone’s tried full ice & water shield coverage on older homes? I know it’s expensive, but we did it on a low-slope ranch last fall after the homeowner had two leaks in three years. No problems so far, but I wonder if it traps moisture underneath if the deck isn’t bone dry. We always try to let things air out, but sometimes you’re racing weather.
Flashing is a big one too. I used to think caulk was enough for patch jobs, but I’ve seen water sneak in the tiniest gaps around chimneys and vents. Now I’m paranoid about making sure everything’s tucked and layered right. It takes longer, but I’d rather spend the extra hour than get called back mid-January.
One thing I’m still figuring out is attic ventilation. Some of the older houses around here have almost none, and I’ve read that poor airflow can make splitting and warping worse. Anyone have tips for retrofitting vents without tearing up the whole roof? We’ve tried ridge vents but sometimes the framing just doesn’t allow for it.
Anyway, I’m still learning, but it seems like a lot of the splitting comes down to moisture getting trapped and decks flexing with the weather swings. Prep work’s not glamorous, but it definitely pays off when you don’t get callbacks.
- Had the same debate about full ice & water shield on my 1960s ranch. Ended up just doing eaves and valleys—my contractor warned about trapping moisture too, especially with old plank decking.
- Swapped to synthetic underlayment last year. Not cheap, but way less stress during storms.
- Attic venting is a pain. My house had zero vents (thanks, 1962). Added two gable vents—wasn’t pretty, but it helped. Didn’t want to mess with the ridge since the rafters are all over the place.
- Agree on flashing. I used to think “more caulk = more better” but learned the hard way that water always finds a way in...
- Prep work’s boring but yeah, I’d rather binge podcasts in the attic than deal with leaks mid-winter.
I’m with you on the moisture concerns—my place is late ‘50s, and full ice & water shield seemed like overkill. I did just the eaves, valleys, and around chimneys. Never had an issue with leaks, but I do check for soft spots every spring. Synthetic underlayment was a game changer for me too, especially after a few nasty windstorms tore up the old felt. As for venting, I tried those roof vents but ended up with gable vents since my rafters are all spaced weird. Not pretty, but it dropped my attic temps a ton. Flashing’s where I’ve screwed up before—now I just take my time and use the right stuff instead of globbing on caulk everywhere. Prep work’s boring as hell, but skipping it cost me a ceiling patch one winter... lesson learned.
I hear you on the flashing—my first winter in this house, I thought a little extra caulk would do the trick. Ended up with a water stain right over my bed. Since then, I stick to the basics: fix what’s needed, don’t overdo it, and check things every fall. The synthetic underlayment is worth every penny, especially when you’re trying to stretch your dollars and avoid having to redo stuff after a storm. Gable vents aren’t pretty here either, but they work... sometimes you just gotta go with what fits the house and budget.
- I get what you mean about not overdoing it. My first instinct was always to add more sealant, but sometimes less is more, especially around flashing and vents.
- Synthetic underlayment’s a game changer for sure. Costs a bit more up front, but I’ve seen felt just disintegrate after a couple seasons of freeze/thaw.
- Gable vents... yeah, not the prettiest, but they do help with airflow. I’ve noticed if the attic’s not vented right, you get way more splitting and curling on the shingles.
- Curious—have you tried ridge vents? I’ve heard mixed things. Some folks swear by them, others say they’re just another place for leaks.
- Also, anyone dealing with ice dams? I’m in the Midwest and those things are brutal some years. Wondering if heat cables are worth it or just masking a bigger insulation problem...
