Cellulose is definitely messier to install than fiberglass batts, but if you’re renting a blower and have a helper, it’s not terrible. The real pain is if you have to dry it out after a leak—it clumps up and you pretty much have to shovel it out and replace that section. I’ve found it does seem to “bounce back” better than fiberglass, though, if the moisture was minimal and you catch it fast.
On green roofs: most of the failed assemblies I’ve seen were on flat roofs, yeah. Drainage is everything. If the waterproofing layer isn’t perfect or drains get blocked, water just sits there and eventually finds a way in. Sloped green roofs are less risky but still need careful detailing around penetrations—honestly, it’s not something I’d DIY unless you’re really into building science.
For spring checks, I use a cheap moisture meter in the attic—just poke around near vents and valleys. It’s caught a couple issues before they got serious. Visual checks outside are good too, but sometimes leaks start small and don’t show up until they’ve done some damage inside.
Metal roofing with synthetic underlayment has been solid for me so far (5 years in), but the upfront cost was rough. Haven’t had to touch it since installation, though, so maybe it’ll pay off long term… time will tell.

Right there with you on the moisture meter. It’s amazing how much damage starts in those hidden spots. I’ve seen people skip the attic check because “it looks fine from the outside,” then months later they’re tearing out moldy insulation. Had one place where the only sign was a faint water ring around a nail—turned out to be a slow drip from a cracked vent boot.
On cellulose, I actually prefer it for sound and coverage, but yeah, when it gets wet you’re basically scooping oatmeal out of your rafters. Fiberglass is easier to dry out, but it loses its loft so fast. I always tell folks: if you’re crawling around up there and it feels like a bog, do yourself a favor and just replace that patch.
Metal roofing’s been a trend in my area too. The sticker shock is real, but after seeing asphalt shingles curl up after just one rough winter, I get why people are switching. No system’s perfect, but I’d take fewer repairs over time any day.

I get the appeal of metal, but has anyone here tried green or “living” roofs? I put a small sedum section over my porch last year—honestly, it’s been surprisingly low-maintenance and seems to help with runoff. Not sure how it’d hold up on a full house in our climate, though. Anyone else gone that route or looked into the insulation benefits? I’m still weighing if it’s worth expanding.
- Tried a full green roof on my garage two years ago (zone 5, Midwest).
- Maintenance has been way easier than I expected—just some weeding and checking drainage after big storms.
- Insulation is real: garage stays cooler in summer, warmer in winter. Not dramatic, but noticeable.
- Only downside: initial setup was a pain—had to beef up the structure for the extra weight.
- If your porch section’s doing fine, scaling up could work, but definitely double-check your roof load limits first.
- Metal’s great for durability, but I’m sticking with green for the runoff and temp control.

That’s what kept me on the fence about going full green roof on my shed. I had visions of the whole thing caving in after a heavy rain, but maybe I was just being paranoid. Midwest winters aren’t exactly gentle, and I’ve seen what ice dams can do to regular shingles, let alone a layer of soil and sedum.
I’m with you on the insulation part. My neighbor did a green roof last year and he swears his garage is way less of a sauna now. He did mention the same thing—setup was a bear, but now it’s mostly just pulling weeds and making sure nothing’s growing where it shouldn’t be (like right over the gutters).
I’ve got metal on my main roof and honestly, it’s been bombproof through hail and snow, but it does get noisy in a downpour. Sometimes I wonder if trading that for a little more peace and some greenery would be worth the hassle... but then I remember how much I hate heights. Anyway, hats off to anyone who pulls off the green roof thing—it’s not for the faint of heart.
