I was up on my roof today and despite crawling and trying to be gingerly
with my 250 pound frame, I cracked a few roof tiles.
Actually, they're 're-roof' clay tiles, which, apparently, are thinner
than original roof tiles (they're only about a half-inch thick or less).
I realize I 'should' replace the broken clay tiles ... but I was just
wondering, since the cracks are brand new and all the pieces are
there ... is there any solution that involves simply gluing them back
Just wondering if that's a viable alternative for minor roof repairs?
I'm not sure what a 'personal approval' is, but I had to take down a torn-
apart chimney enclosure.
I have to go back up to snap some pictures the team asked for.
Plus, I have to go up to fix the tiles!
I've learned to walk on the arches - but even then, I crack a few every
time I go up there.
I wonder if a hot-glue gun, which heals in seconds, will take the hot
Interesting. I didn't think anyone actually glued a tile ... but I really
don't want to re-roof the whole section! (I already bought 100
replacement tiles - I just don't really know how to do the re-roofing
Here is a picture of the newly bought tile shape that needs to be glued.
Notice how 'thin' this tile is (US Tile Claymax).
The only problem with the suggested epoxies, I think, is that I would
think we'd need a quick-dry which will 'fix' while I'm still up there on
the roof, holding the parts together with my hand.
Did we come to a consensus as to which glue will:
a) Be strong enough to hold porous tile together
b) Be quick-drying enough to set in a minute or two (while being hand
c) Be durable enough to last the heat and cold cycles on the roof
Ive glued things together with slow set epoxy that was difficult to
hold in place while the glue was drying by also using a little fast
set glue like a 5 minute epoxy or super clue .Superglue should hold
tiles pretty good.
I've never had success with cyanoacrylates on (a) porous surfaces, and
(b) large surfaces.
The problem with cyanacrolates (e.g., superglue) is they the glue itself
is extremely weak. So, while the molecular bonding is fantastic, you
really want a single molecule layer thick of the stuff, no more, no less.
That's really hard to do on rough cracked chipped porous surfaces like a
clay tile, even a recently broken clay tile. So, from 'my' experience,
superglue would be one of the worst possible choices for clay tile.
Besides, we're talking a LOT of (what turns out to be expensive) super
glue! Even if it did work (which I really doubt it would).
But, not to sound condescending, I 'do' welcome the suggestions. I'm
particularly motivated now that you guys tell me roofers habitually glue
roofing tiles (I hadn't expected that).
Is there an epoxy that can set while I'm on the roof holding the tiles
(two minutes or so)?
the faster epoxy sets, the weaker it is, in general.
if you can remove them, glue them in a jig, and heat them gently, then
replace, they'd be stronger. you could also laminate them on the down side
with some fiberglass mat wetted with epoxy for reinforcement.

Here is a picture of a new one.
I guess I'm now morphing to the idea of replacing them.
They only have a single hole ... it's on top ... in the middle. One nail.
Also one wind-hold-down hook on the bottom (which hangs off the prior
Can anyone point me to a howto for replacing a single roof tile of this
type? (Claymax, US Tile company). Yes, I have an email pending to their

Interesting idea. That would give the tile a strength and water
repentance that simply gluing might not.
It might be a bit hard to get UNDER the tile though.
Here is a picture of the tiles in place, for example.
It might be, that if I have to remove the tile, I may as well replace it
then. The thing that scares me is HOW to replace just one tile in a sea
My guys use plain ol' roofing asphalt. It doesn't need to set that
quickly, the tile is just sitting there.
My tiles tend to crack/break across their width, so slapping some
asphalt on both pieces is easy and they don't have to remove the
fastened top of the tile.
No problems with their technique over 15 years.
