Any thoughts as to what is causing the corner siding to warp? Siding is Certainteed Monogram – builder claims it is because the siding is dark and is absorbing heat. Not sure this is a 100% sole, valid reason as all houses would be white then. Should note major issue is with all corners and siding on the front of the house. Any thoughts would be greatly appreciated
Natural light, taller ceilings, and more functional spaces transform this midcentuary-modern home.

I’m not familiar with vertical vinyl but one cause for buckled siding is that it’s nailed too tight and the other is the siding is too tight into a corner.
The nailing slots are elongated for a reason, to let the siding move. In cold or shade it doesn’t move much. Introduce the sun and heat, it grows. Even on the end laps there is room that should be allowed.
Is the front of the house in the sun?
Front of the house does receive the most sun. All corner pieces are very tight and have no play. This issue started in the summer. This specific siding was an upgrade for both thickness and color. No such warping concerns were expressed by the builder before installation. Home is located in PA.
When I enlarge your first photo it looks like the edge is buckled. Like I said, I’m not familiar with that vertical siding and if corner trim is different for it…..
But, the buckled part looks suspiciously to be a result of it not being allowed to “float” in that trim.
You’re going to make me put down my book and search for vertical siding corners……
Maybe.
Unfortunately, it is doing for both horizontal and vertical areas on the front of the home. Each corner section has this type of warping along with a few boards nearest the corners. I have reached out to Certainteed to see if they are willing to assess as the builder claims "the sun" or "dark siding can do this".
Dammit
Wasted time typing out my thoughts and something tied up but here’s a link to installs for vertical siding.
https://www.vinylsiding.org/installation/installation-manual/vertical-siding-installation/
Read down a ways to get a feel for the process and note that it should “hang” just like horizontal….
But being “hung” means the top needs to be able to move up but do not center the nail in the top slot…..should be higher.
Study the backer also, that keeps the cut siding held out in that corner ……
The first time I wrote this was better but sh*t happens.
Study up on the install and come back for more
I appreciate the information. Guess the proof is only known when pieces are removed and can eval the nailing pattern and if they followed best practices as outlined.
Well,
There is a way to release the “lock”on the siding so you can redo nailing or take a look.
If you hunt on vinyl siding tools and get past saw setups etc…..you can find a siding removal tool that unlocks siding. You can release one pc of siding lock, lift the bottom and technically it should “slide back and forth. And of course you can see how tight the pc it was hook to is.
Just an additional question to check on the installers. Did they drill weep holes in the bottom J-channel?
Hack, would be interested in hearing the outcome.
Good luck.
Probably too tight on the nails. Vinyl expands and Contracts a lot, replace the pieces and it should be fine.
Remember to note: the sider should do the repair.
Definitely. Not the HO job to fix a Tradies work while they cut their teeth the first time. Experience is the young siders tip.
