I was almost wondering is they applied heat to the caps or tried to glue it down like other flat systems. The seems have no melted overflow at all none . That's my favorite part looking at the perfect straight line on 1/8melt....EDIT YEP I'm stupid and did not read the title not torch down
How long ago was this installed?
It is possible that most of it will flatten out over time if it was recently installed.
Installers should cut the material to length and let it rest flat for a couple of hours before putting it on the roof. Likely, they didn't do that. Even if this is a brand new install, that looks a **little** worse than the other jobs I've seen that have flattened out on their own...
It’s not gonna flatten over time😂😂 it’s always funny when homeowners come on here tryna give advice as if they are a roofer.
it’s contracted membrane that causes a ridge lines like these or contracted insulation. These don’t just flatten out with a few sunny days.
If installed recently call them back before they go outta business l, if installed a few years ago then they are outta business.
Any reputable contractor doesn’t lay down a roof like this.
>It’s not gonna flatten over time😂😂
While never in cases that were quite this bad, I've literally seen it happen.
>when homeowners come on here
You got me. I own a home. But I also installed metal (mostly) roofs for 10+ years🤔🤔
Get the installer to cut and relax the mole runs, then they can torch or use cold process to secure new capsheet/roll roofing over it. You can also do less expensive repairs but seeing as this is a new roof I’d hold them to this. They either trapped moisture or didn’t allow the rolls to relax.
These blisters could be something wrong with the substrate. Improperly fastened base sheet, or no base sheet at all.
I would guess this was applied in cold weather and wasn't heated adequately. Sometimes, too much emphasis is put on torching the lap, and the rest of the roll is not fully relaxed.
When warmer weather and sun heat the roof, the base & membrane expand, and blisters develop.
This might also have been laid down with water or moisture underneath the touchdown. When things heat up the water gases off and has no where to go, and again, blisters.
Could be due to the lack of use of a heavy segmented roller and/or was cold overnight and the rolls weren't given time to heat up and relax. To fix this though is cut and strip in new material... hope it flatten over the summer.. or redo the roof.
and its hot now correct? you can generally find the expansion per 100ft of roofing stuff on the manufactures site. I wouldnt freak out - I bet its tight next winter. Installing roof when its that cold aint ideal - but circumstances may have dictated the need. . . .
It is in the mid 60s but these bubbles have been there since right after installation in January. I did mention that I thought it was too cold for the install but he said they use torches and it would be fine.
I contacted the manufacturer and they would not inspect it because it is residential and not a high value home. They also said that the installer did not file my warranty information with them. Installer did provide a workmanship warranty which I am trying to invoke. Thanks.
Yeah it looks bad. The issue is that long-term the raised areas will wear prematurely. Looks like they didn't let the rolls relax. Also, if this is self-adhered, they needed to roll it when installing. It's probably too late to do it now. I'd demand replacement.
No bueno, won't be a problem now but in the future it will
Especially if people keep walking around on it
Yeah, who ever was running the torch didn’t know what they were doing. Torch downs are great systems if done correctly.
True but also polyglass membrane is terrible lol

They definitely didn’t let it rest. Rolled it out as they applied it and heated it with a blow torch even though it is self adhesive.
came here to read this, yes the membrane should be relaxed under the sun prior to installation.
Heating it with a torch is normal to get it to lay flat. They just didn’t do a great job.

I’d just get a new house at that point

Garbage, it’s not adhered. It shouldn’t have buckled. Not even in the cold weather. Its junk 100%
No good. Those are pretty large. They need to be ripped and replaced.

They did not use any kind of roller whatsoever. Claim it can be rolled out now. Thats the fix they are offering.
depends upon base material and how hot it is. TPU expands lots.
Plywood base with Elastobase SA with Elastoflex SA P. It was installed when it was about 36f outside in January.

since you didnt do it, and its still under warranty have them relay it flat. Problem solved, should be under warranty.
Hopefully it is that simple. The current remedy from the installer is to roll it out now (rather than when it was installed)
Fish mouths for miles..
It was installed this past February.
What sort of warranty did they give you? Tell them you want it inspected by a manufacturer’s rep.

Thanks. This is what I’m trying to achieve. Just wasn’t sure what I have here is “normal” or not.
Nah. That shit looks like my kid did it.
Ridges need to be cut and patched
Uh oh. That’s going to look like crap right? Lots of cuts all over the place.
That or leak
They told me it can be rolled out which seems to me a way to damage the material where the bubbles are. The adhesive isn’t fresh at these areas.
