The fading’s annoying, but at least you’re not patching holes every other season.
That’s true—you trade one headache for another. I’m curious, though, for those who went with rubber, did you notice any sagging or bowing over time? I’ve seen a couple jobs where the extra weight wasn’t accounted for and it definitely caused issues down the line. Is anyone reinforcing their rafters or just hoping the structure holds up? I always wonder if the long-term maintenance ends up being a wash compared to asphalt.
Rubber roofs are a bit of a double-edged sword, at least in my experience. I put down EPDM on my detached garage about six years ago—figured it’d be a “set it and forget it” situation. It’s held up better than any roll roofing or shingles I’ve tried, but the weight thing is real. My rafters are original from the 1960s and let’s just say they weren’t exactly overbuilt. I noticed after the first winter (we’re up in Michigan, so snow loads aren’t exactly gentle) that there was a slight dip developing in the middle. Not dramatic, but enough to make me nervous.
Ended up sistering a couple of the main rafters with 2x6s, which was a pain because the space is tight and I’m not exactly built for crawling around up there. But it did seem to stop things from getting worse. I’d say if your structure is even borderline questionable, some reinforcement is worth considering before laying down rubber—especially if you get much snow or have a low slope.
Maintenance-wise, I haven’t had to patch anything yet (knock on wood), but the color faded faster than I expected and there’s definitely more pooling than with shingles. That said, at least I’m not up there every spring chasing after blown-off tabs or trying to nail down curling edges.
Honestly, if you’ve already got a beefy frame or you’re willing to beef it up yourself, rubber can be less hassle over time. But if you’re just hoping the old bones will hold up... might be rolling the dice a bit. Every roof seems to have its own personality quirks, though. Maybe mine’s just dramatic.
You handled that dip the right way—sistering those rafters is never fun, but it’s a solid move. I see a lot of folks just slap on new roofing and cross their fingers, so credit where it’s due. The pooling you mentioned is pretty common with low-slope rubber, especially if there’s even a hint of sag. I’ve seen some people add tapered insulation to help with water flow, but honestly, reinforcing the frame is usually the smarter first step. Color fading’s kind of a given up north, but at least you’re not chasing loose shingles in the wind... which I’d take any day over another winter crawl in an attic.
- Sistering rafters definitely helps, but I’d argue tapered insulation shouldn’t be an afterthought, especially with low-slope rubber.
- Seen too many reinforced frames still end up with puddles that slowly eat away at seams.
- Tapered polyiso isn’t cheap, but it’s a one-time pain that keeps water moving—less freeze/thaw stress, less splitting.
- Color fading’s annoying, sure, but pooling is what really shortens roof life up here.
- If you’re already opening things up, adding that slope now saves a lot of headaches down the line.
