About 2 months ago I had my roof repaired. We had a bad storm and the corner part of the ridge tiles (closest to the bottom of the roof) blew off. I hired a roofing company who replaced that stack of tiles on the corner of the roof. Yesterday, I found that same stack on the ground. We have not had any storms that would have caused the tiles to blow off. I noticed that these tiles have some kind of thick black adhesive between each tile in the stack, but on the original stack that was replaced, the tiles were nailed together. I am going to have the same company repair their work, but I am wondering should I ask them to use a nail instead of this adhesive to hold the tiles together? Did they take a shortcut by not using a nail?
Yes
Yes
Dennis, did you notice he said concrete tile?
If so, do you still feel that way?
You use a 8d or screw to fasten it UNLESS you have a tile above it that you want to save.
You cant instal a nail or screw through these tiles because the tile above it covers the fastener hole.
I believe they used the wrong adhesive.
The adhesive should be specific for concrete tile such as “RT600”. OSI RT-600.
Also… TILE BONDâ„¢ Roof Tile Adhesive by Dow Building Solutions is an example of some spray foam that roofers are using to install field tiles exclusively without metal fasteners.
I haven’t done it. But it does peak my interest.
The last ridge tile is the only one that can’t be nailed, but it can be wired and glued in place with a better adhesive.
correct. The last ridge tile that goes under
the tie-in point ridge tile cant be nailed or screwed.
But the other ridge tiles from the eave up to the transition point should be screwed.
I would ask for the correct screws and some RT-600.
Sorry about that dennis, i missed the “Ridge” part.

I’ve used the sparay foam down in sunny ol fl. seems to work pretty well and in my opinion makes your tiles a lil more durable.

Thankyou for speaking up. I do wonder if it would make the tiles less or more breakable. I would think that it would make the broke tiles harder to switch out. What was you experiance with that?
I can remove a broke concrete tile installed with a screw in under a minute.
How long would it take me if it was installed with the foam? Lots and lots of broken tiles to fix after a completion of a job.
The last tile can usually be fastened with a modified hurricane clip or slate hook, or wired. I work mostly on steep roofs/clay tiles. Adhesives and caulk don’t work so well on steep hips. And I hate cleaning five layers of tar/silicone/urethane etc. off of tiles to make a repair. I can’t imagine the PIA of tearing off a fully adhesive adhered tile roof.
The roofing industry is rapidly moving to adhesives over nails or screws. Both on residential and commercial roofs. Whether they are better…only time will tell.
We did a brand new concrete tile roof about 2 years ago and they had this caulking that harden like concrete.
Most of the tile roofs around these parts are old Ludowici-Celadon, a lot of them were put on in the late 1800s when that style was popular. I repair a brocken tile by shiming the one above the replacment tile “a door wedge block works great for this” and set the nail with a flat bar and tap in the nail. Its a bit of a knack but you can never tell it was a replacement when im done. “F those hacks that use glue and foam”. on falshing replacement I number all the tile in the area im working and pull them out and neatly stack them on a plank “in order mind you” and put them right back in again. It always makes this harder to save the tiles when some jackass puts in black tar or some type of bullshit glue. a good slater does not need any of that.
JimB, you’re just an idiot. Don’t you know that if there is a new product, it’s better? Look at Masonite, Asbestos shingles, asbestos felt, super glues, etc.
Before long, we’ll be able to just brush some glue down and frame houses, glue on roofs, (see SBS), and even use glue instead of bolts to hold heads on engines. Get with it man!
How can you guys knock it before you try it? I understand they didnt have adhesives and foam a thousand years ago when you guys first started roofing
and I know a lot of you old school guys abhor any change so much that you would be incapable of giving an unbiased opinion. Just cause it’s new doesnt make it right but at the same time doesnt necassarily make it wrong either.
Judging a product by how easy it is to remove or make repairs to is in my opinion silly on so many levels That I dont know where to start but thats kinda like saying we shouldnt use ice and water shield because it’s gonna be hell for the next guy that has to tear it off, besides a “good roofer” shouldnt need all that underlayment. or maybe we should stop buying new cars because of the new technology used in them every year,not to mention how much more difficult they are to repair.
I would not want to be anywhere near a tile roof in a hurricane that is held together with glue. We recently did work on a clay tile roof and were able the change all the flashing to new copper, the tile were all reusable. you just number them pop them out and put them back in again after you install the copper. This would have been impossible if they were put in with foam or some other crap you clowns are touting. Slate and tile roofs can often last hundreds of years but you have to able to do the periodic repairs like changing the metal flashing or field tile replacement. There is no need to try to change the ways its always been done. Its like soldering with irons as opposed to a torch.

I like the way you write and think cj. I look forward to hear more about your experiences and views on this forum.
I think i have a very valid concern and you didn’t answer the question. I guess switching out broke tiles installed with foam is SO EASY that you didn’t even bother addressing it. Is that correct?
Let me ask the question again. Have YOU personally removed a broken tile installed with foam?
Can i successfully remove a broken tile without damaging the surrounding tiles? Now that i really think about it…I am thinking no. Because now the tile above it is locked into place. I cant put a wedge above the tile i want to replace. How do i clean out the old foam on or above the baton when the tile above it is totally in the way.
How do i slide in a new concrete tile and slip it on to the baton when the tile above it is locked into place with foam and i cant wedge it up?
And rooferj–“and set the nail with a flat bar and tap in the nail.” Wow you can drive an 8penny nail with a flatbar with a maximum of a one inch swing?
Wow, you must be Chuck Norris!!!
Keep in mind that tile roofs are installed different in new england than down there. we use 2" copper slaters nails. not an 8D. The flat bar method is tried and true and a lot better than a hook or clip that you can see. I may do the clip method in some situations like on a hip . No I am not Chuck Norris.
I really am confused now. I don’t recall being taught, or reading of any roof instructions spec’ing an 8d nail.
Either screws, Hot-dipped, and copper are the only things I have. I do buy 1"eg for felt since EG is for felt only, not any roofing material.
@ rooflover…Sorry I did’nt answer your question. my last reply was more of a rebuttal at those so quick to start the name calling (“hacks, clowns”, etc) because someone does things different than them or the traditional way of doing it…
To answer your question no I havent done a repair in which the roof was applied with foam, nor have I applied a slate roof with foam or adhesive. guess I should have been more clear on my first post.
I have applied spanish tiles in fl with the adhesive foam and in my opinion it seems to not olny hold pretty well but also fills the void in them,making them very difficult to crack or break.
Not saying this is the best way for every apllication definatly not for any that lay flat like slate and even when installing certain products with foam it’s not like you old school guys could’nt still stick a nail in each one to stick with tradition.
@rooferj trust me you wouldnt want to be anywhere near a tile roof in a hurrican period. down in florida metals oxidize so quickly that your nails will never last the life of that tile roof. most of the tile roof repairs that I went on after all the hurricanes of 04, you could just walk up to any random area of the roof and pull tiles out with your hands, the nails had turned to dust long ago.
