I hear you on the moss—north side of my place is green half the year, no matter what I try. Composite tiles have been a solid upgrade for me too, especially after losing a chunk of roof in a windstorm last fall. If anyone’s dealing with moss, I’ve found that a gentle scrub with a soft brush (on a dry day) does less damage than pressure washing. Just gotta be careful not to lift the edges. And yeah, the quieter rain is a game changer... didn’t realize how much the old metal roof was amplifying every drop until it was gone. Maintenance is still a thing, but at least I’m not patching leaks every winter.
Switching to composite tiles really does change the game, especially if you’ve dealt with storm damage and the constant drip-drip soundtrack from metal roofs. I see a lot of folks surprised by how much quieter their home gets after making the switch—people underestimate just how much noise metal amplifies. And yeah, the moss situation on the north side... seems like nobody’s immune to that. Even with the best materials, that shady damp never really goes away.
I tend to push back a bit on the pressure washing thing, though. I get why people want to blast moss off—it’s fast and satisfying—but I’ve seen too many composite roofs with their granules stripped or edges lifted after a few aggressive cleanings. That soft brush technique you mentioned is definitely safer, even if it’s a slog. For what it’s worth, some of my clients have had luck with zinc or copper strips near the ridge. They won’t solve everything, but you can sometimes slow down the green takeover without scrubbing every season.
Maintenance is always going to be part of the deal, no matter what material you pick. Composite has its own quirks—edges can curl if you’re not careful, and I’ve seen some cheaper brands fade faster than folks expect. But if you’re not patching leaks every winter, that’s a huge win in my book. Out here, we get windstorms that’ll peel back metal like a sardine tin, so composite’s weight and flexibility make a real difference.
Curious if you noticed any change in your heating or cooling bills after switching? Some people swear composite helps with insulation, but I’ve seen mixed results. Either way, sounds like you made a solid call—peace and quiet during a rainstorm is worth its weight in gold.
The noise difference is real—metal roofs can turn a mild rain into a full-on drumline. I’m with you on the pressure washing debate; I’ve seen more than a few composite roofs get chewed up by overzealous cleaning. The zinc strip trick does seem to help, though it’s not a cure-all. Curious—did you notice any issues with attic ventilation after switching? Sometimes folks forget that composite tiles can trap more heat if the airflow isn’t dialed in, especially in older homes.
That’s a good point about attic ventilation—honestly, I hadn’t really thought much about it until after the first summer with the new tiles. My house is from the late 70s, so insulation and airflow aren’t exactly state-of-the-art. After swapping out the old asphalt shingles for composite, I did notice the upstairs felt warmer on those really hot days. Ended up crawling around in the attic to check things out and realized one of my soffit vents was basically blocked by old insulation. Cleared that up and added a solar-powered fan, which seemed to help a bit.
I’ve heard some folks say composite tiles are “cooler” than asphalt, but I’m not totally convinced—at least not with darker colors. Mine are charcoal gray (bad call, maybe), and they soak up heat like crazy. The noise difference is real too—rain isn’t nearly as loud as it was with metal, but you’re right about pressure washing. Neighbor down the street blasted his roof and now you can see all these weird streaks where granules got stripped off.
Curious if anyone’s tried those reflective coatings or lighter colored composites? Do they actually make a noticeable difference in attic temps? I thought about painting mine but worried it’d void the warranty or just look patchy.
Also, has anyone had issues with moss or algae on composite? The zinc strip helped a bit on my north side, but it’s not perfect—still get some green patches after a wet spring. Wondering if there’s a low-maintenance trick that doesn’t involve climbing up there every year.
Anyway, overall I’m happy with the switch—just wish I’d paid more attention to venting before summer hit.
- I actually went with a lighter tan composite on my bungalow, and honestly, I’m not sure it made a huge difference in attic temps. Maybe a couple degrees, but insulation/venting seemed to matter more for us.
- I’d be careful with reflective coatings—my neighbor tried one and it started peeling after a couple seasons. Also, most manufacturers won’t cover painted or coated tiles under warranty, so that’s a real thing.
- For moss, I tried copper strips instead of zinc and they seemed to work a bit better. Still get some green fuzz in shady spots, but less than before.
- Totally agree on pressure washing—never again. I just use a garden sprayer with a moss/algae cleaner once a year and it keeps things under control without damaging the surface.
- If you’re happy overall, that’s what matters. The little stuff is just part of owning an older house, I guess.
