Leaking roof and solar panels

Leaking roof and solar panels

Post by Newfhugger on Wed Jul 09, 2014 5:45 pm

It appears that the house I recently purchased is leaking like MAD with the current rains. I have someone to fix (hopefully) the roof but it involves removing tiles, putting down new plastic or whatever and returning the tiles. BUT, I have a 16 panel solar system up there that can't be removed so they can work under it. I'm guessing that part of the problem is from where the panels rest on the roof.

Has anyone had experience with this? My contractor doesn't want to mess with the panels but has some kind of work-around in mind but I'm a bit unsure what he's proposing.

Thoughts? I hate to spend nearly $2,000 US only to have the leaks continue.

Tiles should be covered with fiber and impermeabilizante .... not under the tiles. At least in my opinion. Any kind of flat tiles on top is asking for trouble

Impermeabilizante and fiber can be "molded" around supports for solar, gas tank, exposed rebar ..... or just about anything on the roof

So, the covering goes OVER the roof tiles? Just roll it between the panels and the tiles?

I assume you have un-glazed flat tiles and the only reason to pull them up is if they are loose. Or if they are so embedded with black mold that nothing will stick to them.

I find that around the legs of my gas tank I only need impermeabilizante but around plumbing pipes, electrical and some rebar I cut the fiber to fit and paint it on. If they have drilled into your roof I'd use fiber

No, the tiles are those (I'm going to call these wrong) sort of half-circle tiles that sort of nestle into each other.

That's what I assumed and no you don't cover those. You pull them up and re-do the surface underneath just like you suggested above. I am sure one of the local solar companies could work with the roofers and pull those panels up so it can be repaired under them.

Yep .... you can do what I suggested after the tiles are moved

I'm doing the same on my awning right now.   Has a good slope but still found 2 leaks last week

Generally speaking, the curved half moon roofing tiles are referred to as "tejas"; the flat sub-roof hugging tiles are referred to as "azoteas".

Okay - so, it sounds as though, to do this properly, we need to get a solar company involved to remove the panels?
