Hello, I have a standing seam roof on my home. We had an addition put on the house, which involved tying new roof into the existing roof. I see some potential issues, and am wondering if the experts here can review and comment. I'm wondering if I should consider each these items a problem that needs fixing? I'm primarily concerned about functionality--keeping the house dry. Looks/aesthetics are not a major concern. For example, if sealant is considered a durable and reliable fix, then I'm not worried about the fact that it doesn't look perfect.
I'll post photos for each issue:
Your review and advice is appreciated.
Thanks Chris. A few thoughts.
Sealants are not unusual as a "first line of defense" ... almost a redundant thing and also somewhat to make things look nicer. However, they should not be the only line of defense. The problem is that, once installed, the other lines of defense are all concealed.
The backward sloped transition flashing worries me. I have seen that be a problem before. How much water is coming down from the upper roof and is there any slope to make it flow to that valley on the right?
I assume the ridge cap situation can be fixed?
Not unusual on some jobs for seam ends to not be closed at all. If you're in snow country, the snow tends to open them up as it slides.
I would suggest seeing if the manufacturer of your roofing has someone who can come take a look at the job.
It looks like my photos didn't upload. Maybe too many? I'll try again and create separate posts with photos for each potential issue...
Wow you already answered. Thanks! OK, I won't worry about the open seam ends. The contractor proposes replacing the ridge cap with a wider one, to cover those exposed screws. That seems like a good idea. Although, one of the screws is far enough down from the ridge that it probably won't get covered.
I'm thinking, the reverse slope of the slope transition piece might be resolved by a few strategic whacks with a rubber mallet? The slope above is about 5 feet high. Most water does flow off to the left or right. A little bit puddles up there.
The problem I have seen before with flashings that slope uphill is water builds up and is also held by wind and ends up pushing up under the panels on the upper slope.
