TOPIC: Installation

Over or under vinyl siding?

Return to Installation

Return to Forum

Most metal roofs I've seen have the house's vinyl siding removed and the metal roofing material corner piece is put under the vinyl siding and then the siding is re-installed. On my roof, the installer put the metal roofing corner piece about 4 inches up the outside of the building and nailed it to the outside of the vinyl siding. Is this acceptable? Also, because the roof was about 1 " longer on one side than the other, to make it look better, he cut the metal roofing material, leaving continuous jagged edges from one corner to the other. How should this be fixed to prevent rusting?

Can you send me photos of what was done? On the siding situation, it very much sounds like he took a dangerous shortcut. On the other situation, I am having a tough time visualizing what's going on so the photo will be very helpful. Thanks! My email is [email protected] Todd Miller

yes, the flashing should have been installed under the siding. Any rain coming down the siding will be directed under the metal panels. I am not sure what type of metal roof panel you have, thus I cannot make a recommendation regarding the cut edge. You may want to contact the roof manufacturer. Dick Bus

Sounds backwards to me but post up or email Todd a picture. Eric Novotny

I just got several pictures of the installed metal roofing I referenced in my original post above and will send to Todd, as requested. It looks like I've also got corroding, or something else going on, where edges were cut. Also question whether fasteners were installed correctly? On a return trip because of complaints I had, one of the workers went up on a portion of the main roof to fix a problem and on his way down, he pounded in 4 fasteners that were present but had not been nailed or screwed in! I can't see the top of the roof, just the addition and porch, so I don't know about the main roof, but would like to know if the areas seen on the roof I took pictures of look OK. Also concerned that there is a hump where the metal roofing surrounds the smoke-stack from furnace and snow collected there this winter instead of sliding off. I'll send pictures that I hope will show my concerns. Thanks, in advance, for your expertise in helping me to sift through my concerns.

Mr. Miller, Yesterday I sent 2 pictures in one e-mail and 1 picture in another, all through my juno account, as other attempts got blocked. Did you get them? Please advise. Thanks!

We had an installer really hack up our metal roof install on our house and our rental house. My wife called your hotline and we didn't get a response. We have tons of buckles, scratches, dents, rust from the installer using a cutoff wheel. We need an experts opinion for our insurance to go after the installer. Please contact me for pictures. We have a bunch. Plus they installed 4 skylights. Zero flashing was used. Plus the flashing on the chimney isn't under the roof. They used silicone sealant. It's horrible. Thanks, please help Brian

I am very sorry to hear this. First of all, I'd suggest contacting the manufacturer of the roof to see what help they can provide. If you wish to have my input, feel free to email photos and additional information to me at [email protected] Todd Miller
