Lifted shingles - suggestions?

[Arne73]

This roof is about 20 years old and started ******* up like this about 5 years ago. The plywood underneath looks good from the attic side. This is the north side, south side is fine.
Does anybody have any ideas regarding whatmay have caused this and more importantly what I should do to correct it?

 

[Paco Pena]

Those two lines of unhappiness look to be about 8 feet apart. To me that suggests an issue with the roof sheathing.

That much buckle, and I would guess wet tar paper, and bubbling. Remove singles and inspect. If I am correct, the only way to completely insure it doesn't happen again is to use synthetic underlayment but that is a lot of work and money.

Best is to just repair and hope for best until you redo roof.

 

[cgrutt]

I'm surprised you say the plywood looks good from attic it looks like the sheathing may have actually pulled loose and pushed up from underneath. In any event that's pretty bad and seems to be caused more by physical damage than just age related curling. Aside from the two main sections it looks like there are some other problems throughout roof. It may just be time for a tear off and replace. Where are you located?

Was there any high winds before it happened? Possible wind caught underneath and lifted some overlapping sections. If that's the case it may not have been nailed adequately. Good luck.

A 20 year old roof with this kind of damage should really be replaced in my opinion. If the roof was newer I would open up the area and fix just that area, but it is a pain in the rear to do. I replaced ten to fifteen shingles on my roof and it was not particularly easy. This would be a bigger area.

The damage is strangely coincident with the bay window. Is it rafter/ridge beam construction, or trusses?

 

[Rusted Nut]

The severity of the buckling tells me the sheathing buckled. The shingles themselves don’t look too bad for 20 years old. If roof replacement isn’t in the cards right now, you could remove the shingles in the area of the buckle, fix the issue and re-roof those places.

 

[racecougar]

Agreed that I'd consider it time for a roof replacement. There is more going on there than just the two really noticeable buckles.

I bought a house with a roof like that. The roof was 23 years old. I was told by a roofing friend that shingles manufactured around that time had a defect, something with the way the layers were bonded together I think. The plywood underneath was great, only half a sheet needed to be replaced on a 45 square roof.

 

[Whitworth]

Maybe a roof leak is causing delamination of the sheathing at the edges.

 

[PCustoms]

Time for a strip and re-roof, those shingles are shot.

Whatever the underlying issue is will be exposed at that time. As someone else said, my bet is that section of sheathing saw a leak (or 2) and is shot.

How's your venting?

 

[oldmxracer]

Looks like a major sheathing problem to Me. At least remove the buckled-up shingles and have a look always could just then patch it in if full replacement is not in the cards at the moment. As already asked how is Your venting ? If it is not leaking yet it will be !

 

[Arne73]

Thanks for all the replies

-I'm located in eastern Will County, IL.
-When I first noticed the damage there hadn't been any high winds.
-Roof construction is trusses.
-Venting is soffits and several vents on the opposite/ south side just below the ridgeline. A 21" gable fan on a 120F thermostat, blocked off in winter.

You have moles - very stupid moles. Eventually they will starve to death.

UPDATE:
Roof is 26 years old. The shingles are 265 lb/ square, 30 year warranty.
A couple things I got wrong:
-Construction is rafter/ridge
-Plywood does not look ok from the attic.

On my earlier inspections I was looking at the face of the sheeting rather than where they butted up on the rafters.

As you can see in the pictures, the plywood has pulled loose from the rafters. The humps are a each end of an original sheet of plywood that's lifted.

The other areas of unhappiness that @racecougar pointed out are due to sheathing warpage. A more critical inspection shows several other areas where this has occurred.

My plan at this point is a tear off and replacement. I'll get estimates now and shoot for replacement next spring. I may go with a shingle-look metal roof but ultimately it will come down to price.

Thanks again for all the advice guys.

Mystery solved...

Now what's the bare red wire?

 

[Arne73]

Hardwired smokes/heat detectors.
I was looking at them, the CCTV, speaker and antenna wiring. I need to secure them better before re-roofing commences.

Another to-do over the winter: pray for a terrible hailstorm.

That's how I got a new roof anyway.

Well, in my case I didn't pray for it, it just happened, but you know what I mean. All your neighbors will get new roofs too.

Sorry, that's ******** and part of why premiums are going up everywhere.

If your roof is at 86% of its useful "life" and has some obvious structural issues it should not be covered by insurance if a hail storm comes through.

 

[NUTTSGT]

Looks like the entire roof is going to need some attention. At least you are aware that it needs done.

Except the policy each individual homeowner is paying for determines this, not what each of us thinks is "right."

How do I know? I just learned the hard way after a hailstorm and roof inspection that I didn't have the policy I THOUGHT I had. I have an optional rider that I didn't ask for when I bought the policy that allows the insurance company to pay a prorated amount of the replacement cost. This is known as Actual Cash Value (ACV) coverage.

If I hadn't been sold that rider, the law in my state requires Replacement Cash Value (RCV) coverage, which is what most people think they have - If my roof is damaged in a storm, and I need a new roof, I get a new roof.

My specific insurance company is extra sneaky. They call this rider "extended coverage" which sounds like a good thing, doesn't it?

I don't begrudge anybody who's been paying thousands every year for homeowners insurance the opportunity to finally make it pay off. If you're worried about premiums going up, let's talk about the average of $17Billion/year over the last 5 years that my insurance company has reported in profits. I'm a free market guy, but cripes... there's your premium increases.

I totally agree with all of the above!!

I have acv on several things, I'd have to look and see if the roof is one of them. Keeps the premium lower.

I have no issue with acv since if it's close to end of life then you are already planning on paying for a replacement! Insurance is for things you can't plan for.

In Minnesota many insurance companies are switching to actual cash value for roof replacement. They are also increasing deductibles for wind and hail damage. My insurance went to actual cash value plus a $2,500 deductible for wind or hail. The deductible applies to any damage to the house from wind or hail.

The changes to homeowner’s insurance really pisses me off. I had a 60% increase for 2024 and a 20% increase for 2025. I’m paying nearly double for worse coverage. My homeowner’s insurance costs me more my property taxes. If homeowner’s insurance keeps going up like this I might be forced to sell my house as I won’t be able to afford $10,000 a year for insurance.

I am still upset about how my insurance company handled a hail claim in 2015. My vehicle got $4,000 in damage from hail, but they said my roof didn’t get any damage. Right now, between actual cash value and my $2,500 deductible I would get almost nothing if my roof was damaged by wind or hail. (The roof is fully covered if hit by a tornado, burned in a fire, or similar.)

I'll be nice and give you the sticker shock now. My 1700sq ranch I had quoted 3 ways 1) Architectural shingles $10-12k, Pole barn style sheet metal $20-24, standing seam $23-26, steel shingles $34 -38, what I wanted as they looked like slate but unless I hit the lottery it's really hard to justify.
That was strip, replace sheathing only where needed.

Have no idea what metal roofs are going for but the Architectural shingles seems to be in the right ballpark. I'm assuming about 19 squares on the roof?

Once you price out that option you might have to sit down for awhile.

At that price standing seam.

Around here that's probably a $35k roof

Eastern Will County? We could be neighbors.

We had Hamstra roofing do ours this past spring at 24 years old. I recommend them. Not the cheapest, but kept their word and schedule while doing good work.
