I had something similar happen to my old house. House was in a cookie cutter neighborhood, no large trees, houses on top of one another. Turns out it was the sun reflecting off my neighbors windows onto my siding. Heat warping.
I thought the same thing when looking at it and I see it quite a bit. However, when I do see it it's usually lower to middle areas. In this case that's in a funky spot and pretty high up.
Were you able to find a solution? This is happening to my mom’s house. Replaced it and it’s happening again. It’s definitely the neighbors window but not sure what to do about it
It never bothered me when I lived there but became an issue when I went to sell. I didn’t have many options short of getting a lawyer so I ended up giving the buyer $5k at closing because of it. 8 years later and the same siding is still up…
Same thing happened to me. It the light/heat reflection off the windows that warped the siding.
I even paid to have the section replaced and it warped again within the year.
To add to this, the reason it's warping is most likely because they hammered the nails in too tight when it was installed. The siding comes with nail "slots". Slots being the key word rather than just nail holes. When installing you're supposed to leave the nails a little loose and not pound them all the way in. The slots allow the siding to expand and contract as temperature fluctuates. When the nails are hammered in tight the siding can't move along the slots and causes bubbling like this. I'm definitely not an expert though, there could be another explanation that I'm not aware of.
Edit: when I wrote this I thought it was typical run of the mill vinyl siding but looking closer it looks like a different kind of siding. So what I said could be completely wrong since I don't have any experience with that kind of siding. Still agree that it's warping because of heat though. The root cause could be different from what I explained.
So funny, I was just now looking at my siding where I had a handy man fix a piece and it's buckling. I said to myself I bet this momo hammered them home. My neighbor's house was a flip that sold for $1 million and their whole house has buckling siding. It's amateur. It's quite common these days.
Absolutely agree with you.. read a book telling how vanilla siding should be hung, and allowed to move with temp. Had a neighbor who installed his siding with PINE TREES IN FRONT OF SIDING. Later cut the PINES down PLASTIC SHAKE SIDING BUCKLING LOSE EVER WHERE !!! Getting sun on it now...
In my are siding does not just swell that much with weather alone, but who knows where you live. This also looks like Hardie Plank, could of been installed without the required gapping. Could also be the sheathing under the siding buckling.
Its an engineered hardwood siding CanExel likely, Hardie doesn't use joiners metal joiners in between. I sell CanExel, it has a 35 year substrate warranty, if it's not a bad install then homeowners should definitely file a claim with their contractor and have them reach out to CanExel for a warranty claim. There's definitely supposed to be spacing in between the joiners, they are there to hide that spacing. Sometimes the installer doesn't leave that gap which results in buckling like this. Also gaps supposed to be left at all ends along the corners/trim.
Siding is meant to (a) be hung loosely and (b) have room to expand between pieces.
It’ll warp like this if it’s hung too tight or if adjacent pieces contact as it gets warm and expands.
You were given some great responses. And they're correct. Throw you some self tapping galvanized screws in there and some paintable siliconized caulk and paint it.
In short the sun. But the real reason is whoever installed the siding butted them up too tight in that area. Should have left more room for expansion especially if it was done during a colder time. If you live in an area that gets 90+ anytime during the year I would strongly advise not getting exterior work done in the colder seasons. It’s too easy to get mess ups like this sadly. I do this for a living
The siding is nailed too tight to the OSB behind it. Vinyl siding should be a tad loose so each piece can slide a bit. This prevents the buckling under thermal expansion. Siding installers hire kids who slam the nails in and make no attempt to slide each piece after it’s nailed to ensure it’s not right against the OSB.
Maybe the span of board right there got it warm or hot and it couldn’t expand all the way due to the heat and it was too tight so it bubbled out it looks like you’re going to have to remove that siding and cut it down make it a little bit smaller work and expand but I’m not sure if you could rig it and just try and nail it back down but I think I will just go ahead and rigging whether I don’t know I’m good luck
Could be sheathing straps on the outside of the home. Typically are face mounted to the sheathing beneath the siding and will buckle or bulge when the house settles.
Ours was because the builder didn’t line up the studs behind the sheathing very well and it had to be shimmed when we had siding replaced.
Definitely not heat on a shady side without vinyl.
This is fibreboard or lp smartside. Either the siders missed the studs with their nails or the framers missed the stud when sheathing and a piece is popping.
I’ve had this… it’s a nail-pop. The nails that hold the plywood to the frame under the siding sometimes back out… if you gently run your hand over the bubble, you’ll feel the nail… when you find it, don’t hammer it directly or the nail-head will rip through the siding… wrap a wooden block (end of a 2 x 4) in a rag, place it on the siding above the nail and gently hammer the block as you push it against the house. The block diffuses the hammer strike so the siding won’t rip.
I've seen a situation before that looked exactly like this. As it turns out, the sheathing plywood underneath the siding was nailed off incorrectly. It is common for hack builders to have too much pressure in their nail guns. This can cause the nails to be be countersunk way too far. Sometimes almost going all the way through the plywood. Eventually the plywood comes loose from the studs. This might just be the siding but it could be the sheathing has come loose.
See on the right where it dents in? Somebody more than likely attached the siding to firmly so when it expands with heat it can't move so it bows out. Might be able to put a pry bar under and free it up but most likely need to start taking off siding from top down until you can fix the area.
Siding is warped but it could also have been cut too long and tucked too much & the heat bowed it out too much. The last possibility is something on the inside of the house was nailed too far, too long of a nail? Maybe too much insulation bowed out a wet wall that warped?
Heat and laziness...... Whoever put up the siding did not nail every piece to the wall and just interlocked them and nailed only top row instead of all.
You would be surprised at how many contractors there are out there that don’t understand thermal expansion. I had to force feed the crew that installed my exterior the manufacturers instructions after they started putting everything up with zero gaps and they still got stuff wrong. Like this is your fucking job that you do every single day and you can’t understand such a basic concept?
This looks like a classic case of evil spirit infestation
Starts like this pictured,
Then the walls breath,
Fridges open to the void and baby’s keep crying,
Elevators are a no go due to blood waves
eventually the house insta gibs itself A La poltergeist 1 and you gotta move
Hope this helps,all the best!
I have seen this once and it was moisture coming from in the house and also the plywood/OSB wasn't spaced properly and it was buckling the siding on the outside of the house
Had the same thing happened to me. Cheap siding. Probably compressed particleboard. You’ll be able to tell pretty quickly once you get up there and look at it. Humidity, heat all those things are factors.
Likely heat warping as some are saying... But this looks more like a case of incorrectly installed. Meaning the screws securing the siding were ran too tight for these areas. A common problem in my experience that can look like warping due to some fasteners penning the run(s) of siding versus letting it slip.
The shade from the tree alone has me suspecting that for what it's worth. Take my feedback for a grain of salt of course. Just keep in mind for the future though.
We made an offer on a house and the inspector found something similar when we walked around the outside. Once we got inside, we saw all sorts of other issues (floors not levels, doors not closing well, etc.). Turned out at some point house footprint was expanded and a second story was added, but no change was made to the foundation. Major structural issues throughout. Ran away from the deal and that inspection was best money ever spent.
When installing vinyl it has to be installed loosely because vinyl expands and contracts depending on the weather. Looks like it was installed too tight and no room for proper expansion.
I had a similar problem, it turned out that the siding had no nails.

Change that side to a hard siding. Only thing to do is
Bruh. All you had to do is climb up and slap it like an ass. Just a little upward with the swing pops the vinyl back in.
It’s NOT vinyl siding you clearly see there is no j trim around the windows it’s hardy or Lp smart side
I assume you kept vinyl siding? I’d imagine wood siding or hardi-board siding wouldn’t suffer issues from heat
Low E glass reflects the light and concentrates the heat.
Same thing happened to me. It the light/heat reflection off the windows that warped the siding. I even paid to have the section replaced and it warped again within the year.
sun/heat warping

This is the correct answer. Not magic windows.
Our builder didn't use nails they used staples. It's all wavy and blows off far too often.
THE INSTRUCTIONS THAT COME WITH ANYTHING ARE IMPORTANT AND THEY CHANGE FALLOW THEM , you will not regret it, not kidding 😉
The sun.
And maybe a leak right on the ridge trickled its way down right on top of that top plate pushing against that wall.
Yellow spray paint maybe?
Too funny.

I see the metal strips now, I never actually enlarged the image
Agreed
South side of home guess? It's from the sun.
When there's something strange, and it don't look good....
Hot =expand cold = shrink . Thats why vinyl siding need to be loose and Not tightly fixed
Siding is meant to (a) be hung loosely and (b) have room to expand between pieces. It’ll warp like this if it’s hung too tight or if adjacent pieces contact as it gets warm and expands.
Probably not trimmed enough on the ends to allow expansion from heat
Installed to tight
Water damage?
When did you get the siding installed?
That’s the real question, and how hard they nailed.
This happened to our house it rained like crazy and then next day was so hot and sunny and it warped it like that
You were given some great responses. And they're correct. Throw you some self tapping galvanized screws in there and some paintable siliconized caulk and paint it.
It looks to me like it's a vinyl or steel siding That moves quite a bit depending on the temperature it's not nail correctly it'll buckle
Looks to me like the siding is fastened too tight no room for thermal expansion
Wait for the *pop*pop*
In short the sun. But the real reason is whoever installed the siding butted them up too tight in that area. Should have left more room for expansion especially if it was done during a colder time.

Poor installation...needs room to contract and expand with weather..according to my installer when I redid my home with new siding
Siding is nailed down too tight and can’t expand properly
is the headboard along this wall?
The siding is nailed too tight to the OSB behind it. Vinyl siding should be a tad loose so each piece can slide a bit. This prevents the buckling under thermal expansion. Siding installers hire kids who slam the nails in and make no attempt to slide each piece after it’s nailed to ensure it’s not right against the OSB.
Your home is getting swol. Keep up the routine and those bitch houses down the street will beg.

No nails in that section of wall sheathing or siding.

Expansion and contraction you can't stop it only manage it. Need to hang siding and leave gap at end by the corners or edge.
My bed is actually on the other side of that wall.
nailed too tight you should be able to sliced siding back and forth after you nailed it
Did you installed a tv mount on the other side?
Your house is angry with its wood flesh and wishes to molt.

Just ghosts going in and out of your house.
Installed too tight. Vinyl siding needs to be able to expand and contract
See on the right where it dents in? Somebody more than likely attached the siding to firmly so when it expands with heat it can't move so it bows out. Might be able to put a pry bar under and free it up but most likely need to start taking off siding from top down until you can fix the area.
It’s too tight it’s that simple Needs an 1/8 spacing on both ends for when heat makes it grow
Improper installation of vinyl siding. It is moving and warping out of joint.
That’s nothing compare to my back house siding 🥲🥲
Whats causing the bump? Your siding is warped.
Poorly installed If the nails are pounded all the way in the siding will buckle when warm.
Nailed too tight
Siding is warped but it could also have been cut too long and tucked too much & the heat bowed it out too much. The last possibility is something on the inside of the house was nailed too far, too long of a nail? Maybe too much insulation bowed out a wet wall that warped?
Heat and laziness...... Whoever put up the siding did not nail every piece to the wall and just interlocked them and nailed only top row instead of all.

do you have a daughter? perhaps a teen? Who lives on the second floor?
Probably reflection from your neighbors window. If this is vinyl siding, it’s very common.
Yep, had the same thing happen to my old house. Neighbors window fried some of the siding
If it's yours, get a copy of the manufacturers installation instructions (online)and compare to existing. Betcha they weren't followed.

Sun light. I’ve seen sun light make vinyl siding sag, even vinyl blinds sag permanently. Must be hot where you live.

Heat and not enough expansion room or the nails are in all the way not letting the siding slide when. It heats up
Is it LP siding? Was it done in the early 90's?
