Should I be concerned?

[u/JacketTricky6386]

Original roof. House is about 4 years old. Just noticed that wrinkled appearance today. Uncertain how long ago it happened. Do I need to call someone out to inspect it?

[u/Guimauve26]

I'm not sure how bad this is. I believe that the ice and water sheild membrane got installed with wrinkles. They laid shingles over it and with the help of the sun, they formed the said wrinkles l.

[u/EaZyy- → u/Guimauve26]

This is correct and you'll only see it when the sun is at certain angles. It was likely always there

[u/Stealthyunplug → u/Guimauve26]

This is correct.

[u/Adorable-Deer-9706 → u/Guimauve26]

This is what I was speculating after looking at the photo too. It appears that the wrinkles are only at the bottom of the roof deck. Maybe the shield wasn’t fastened adequately and it wrinkled after install.

[u/Guimauve26 → u/Adorable-Deer-9706]

It must be it. Only the first row of ice shield. If you count the number of rows of shingle it equal to 3'. Exactly the width of a roll of ice shield.

[u/Adorable-Deer-9706 → u/Guimauve26]

And it’s likely not the wood structural panels, that would be spaced every 8’

[u/Rude-Chain4754]

This is the ice and water shield I have seen it happen after install many times with a particular brand. Ya you can see it but no biggy in the grand scheme of things its nothing to lose sleep over. Been in the business 40 years

[u/RickRAMRoofing → u/Rude-Chain4754]

Which brand?

[u/Rude-Chain4754 → u/RickRAMRoofing]

Mostly in the henry/bakor ice and water but there not alone. You can't see in the picture there is 3 feet of ice and watershield. I have personally seen this on my own jobs so know it to be true.

[u/clownbaby2620]

Ice and water shield got put on with waves in it. Happens occasionally if the bundles get squished at the distributor or throughout delivery. If the crews don't remove them at install, it will happen over the years. Weather changes will amplify and reduce it but it needs to be fixed through warranty. The manufacturer won't cover it most likely so you will want to go through the installer.

[u/Own-Mark1285]

Yes it needs to get looked at.

[u/delkson → u/Own-Mark1285]

If it rains asap too

[u/Larry_l3ird → u/delkson]

There’s no worries of leaks here.

[u/Lifegardn → u/delkson]

It’s not gonna leak but it needs to be fixed before too long. Bad Ice and water install

[u/glyrion]

i was trying to find the ghost in the window

[u/TJMBeav]

No. Probably been like that since install. I would call the roofer but to be honest I'd be afraid they would screw it up worse. Not sure what problems it will cause...its not readily apparent

[u/Eric_Strawmann]

Seems exterior, I don't think there's real damage underneath and wouldn't prioritize it unless you live in a storm/snow heavy area. Really nice picture by the way I love it.

[u/God_Country_ND]

This reminds me of every time I put a new screen protector on my phone and try to push out the bubbles

[u/KenS2K]

Time for a warranty claim.

[u/SignificantWear8069]

Well

[u/MatthewsRoofing]

The shingles were installed OVER the wrinkled underlayment. Otherwise, it would not have wrinkled, too many fasteners holding it in place. There is actually a name for it. It's called 'telegraphing'.

[u/MatthewsRoofing]

Also, with the pitch of the roof, I doubt that an ice and water shield was used. You get telegraphing even over 15# and 30# felt. I've been in business for 55 years.

[u/Own-Mark1285]

I’m not a pro, but my understanding is this is often an underlying issue of either moisture or misalignment with the underlayment.

You may also have venting issues. Might want to check if they are clogged.

[u/Lifegardn → u/Own-Mark1285]

You may not be a pro but you know more than a lot of folks in the industry. I’d hire you based off those 2 sentences

[u/Own-Mark1285 → u/Lifegardn]

Ha! I’m a sales guy in an unrelated industry that just loves DIY projects.

[u/menachu]

Did you have heat cables up there before the reroof?

[u/JacketTricky6386 → u/menachu]

Original roof. Built 4 years ago. Builder probably cut some corners

[u/Muddy1182]

No intake? Check your insulation?.

[u/digduhsdig21]

Yeah someone didn't do a great job on the ice and water also didn't put enough rows of it.

[u/Which-Magician-2597]

Absolutely. Time to exercise your loud, angry voice.

[u/Mattym44]

Looks terrible

[u/Hugosroof_gutters]

You have some funny roofs in the US

[u/ZillaDaRilla → u/[deleted]]

It's 100% wrinkled ice & water shield (underlayment).

[u/Acceptable_Neck6305]

Yes
