Yeah, tile roofs definitely aren't maintenance-free—though they're pretty close compared to shingles. I've had both, and while tiles are way better overall, they still need some attention now and then. One thing I've noticed is that the type of tile matters a lot. Concrete tiles seem to hold moisture longer, especially in shaded areas, making them more prone to algae and moss. Clay tiles dry out quicker, so they're usually less of a hassle.
Another thing that helps is trimming back trees or branches that shade the roof too much. I had a huge maple tree shading half my roof, and once I trimmed it back, the moss issue got noticeably better. Also, zinc or copper strips installed near the ridge can help prevent algae growth by releasing tiny amounts of metal ions when it rains—sounds weird but actually works pretty well.
Honestly though, no matter what you do, you'll probably have to get up there every few years to give it a good cleaning or hire someone to do it. Still beats dealing with shingles curling up or blowing off in storms...been there, done that, never again.
Good points about the tree trimming and copper strips. I've installed those zinc strips on a few roofs, and they really do help keep algae at bay—though they're not a magic bullet. One thing I'd add is to regularly check for cracked or slipped tiles. Even though tiles are sturdy, they can crack from hail or branches falling during storms. A quick visual inspection every year or two can save you from bigger headaches later.
Also, if you're noticing moss buildup, a gentle cleaning with a soft-bristle brush and mild detergent usually does the trick. Avoid pressure washing if you can—it might seem quicker, but it can damage the tile surface or force water underneath. Learned that one the hard way...
Overall, tile roofs are definitely lower-maintenance than shingles, but "maintenance-free" is stretching it a bit. Still, I'd take occasional tile upkeep over replacing shingles after every big storm any day.
Good advice on the gentle cleaning—pressure washing is definitely tempting for a quick fix, but I've seen plenty of roofs damaged that way. Had one customer who insisted on pressure washing his tile roof every spring, and after a few years, he was dealing with leaks all over the place. Took a while to convince him that sometimes slower really is better.
One thing I haven't seen mentioned yet is the flashing around chimneys and vents. Even if your tiles are in great shape, flashing can deteriorate or pull away over time, especially after storms or heavy winds. Had a job last month where the homeowner was convinced his tiles were leaking, but it turned out to be worn-out flashing around his chimney. Quick fix once we found it, but it had him scratching his head for months...
Curious if anyone else has run into sneaky leaks like that—where you think it's the tiles causing trouble, but it ends up being something else entirely?
Tile roofs definitely aren't maintenance-free. They're durable, sure, but nothing is truly maintenance-free—especially when it comes to roofs. I've managed properties with tile roofs for years, and trust me, neglecting them will cost you eventually.
Funny you mentioned flashing issues, because I had a similar situation just last year. Tenant kept complaining about leaks in the upstairs bedroom after heavy rains. Naturally, we assumed it was cracked tiles or something obvious. Had the roof inspected twice—nothing. Eventually, a roofer buddy of mine took a closer look at the flashing around a vent pipe and found it had completely separated from the tiles. Water was sneaking in there and traveling down along the rafters before dripping through the ceiling. Sneaky indeed.
Another thing people overlook is debris buildup in valleys and gutters on tile roofs. Leaves and branches pile up fast, especially if you've got trees nearby, and that trapped moisture can cause all kinds of trouble. Had one property where tenants swore the roof was leaking badly every storm. Turned out it was just clogged valleys causing water to back up under the tiles. Cleared out the debris, problem solved.
Pressure washing is another pet peeve of mine—seen too many well-meaning homeowners ruin perfectly good roofs that way. Sure, it's tempting to blast away dirt and moss quickly, but you're literally stripping away years off your roof's lifespan doing that. A gentle cleaning with proper chemicals (or even better, hiring someone who knows what they're doing) is always smarter in the long run.
Bottom line: tile roofs are solid investments but only if you're proactive about maintenance. Don't fall for the "set it and forget it" myth—you'll regret it later if you do...
Totally agree about pressure washing—seen too many roofs damaged that way myself. Another sneaky issue I've run into is cracked mortar around ridge tiles. People assume tiles themselves are always the culprit, but mortar deteriorates over time and lets water seep in quietly. Had one homeowner swear their tiles were faulty, but nope...just a bit of neglected mortar causing all the fuss. Regular checks really do save headaches later.
