Metal shingle repair - Possible in the field?

This guy got a metal shingle(Tamko?) installed about ten years ago by the local lumberyard, they hadn't done one before and can't stop the leak. Been leaking since day 1, or close.

Am I going to be able to use a zip tool and not completely wreck the upper shingle? Stair stepping up the chimney/siding wall seams VERY tedious.

Problems: -Leaking on long side of chimney, but it could possibly be coming from the upper cricket or siding upslope from it. -Skylights leaking slightly in the middle and little bit on both sides. They were replaced in 1995 when he got a new asphalt shingle roof that only lasted ten years. -Decking popped up in two spots, one can be seen to the upper left of the skylights.

I haven't walked the roof yet, too slick. Going back more prepared next week. Will be installing some anchors for him as well.

As usual in my opinion, seen-it-all has it pretty concisely summed up there.

I love a challenge too, but it has to be accompanied by an underlying conviction that there is a happy ending in sight.

You can talk about the skylight bank alright, but the roof plane seems to cup where it meets the stone and sidewall, the sheathing is buckled, the flashings are all suspect, the field material looks kind of sad and beat and stomped on.

I think it's a tear-off. I've buried myself on stuff like this before. I'm going to take a Darryl stance. Tear it all off and do it right. They won't like it, but they probably don't realize they've already turned cherry-red inside and I wouldn't want to be anywhere near when they flash.

Better get it right the first time. B)

To get more slope, you would just raise the height of the amount of channel you leave. Of course, that decreases the height of your Tinners wings......but if you gain slope, it might be acceptable.....just one of those in-the-field, seat-of-the-pants compromises part of being a roofer that could come back to haunt you later. ;)

I think I can manage that woody. Making slope towards the shingles and fit snugly seems a bit difficult though.

Woo, got to love a challenge.

Unless the skylights are being replaced with Velux units and the original spacing done to their specs, their flashings probably won't work.

The U channel running vertically will have be cut down where the intersections are. I would get the measurement between the lowest part of the skylight frame and the bottom of the U channel. Cut that figure in half and that is the height of amount of channel to cut the channel down to at the intersection. Then take the horizontal u channel that will act as both head and back pan flashing and cut it to fit the desired width (somewhere close to 30") Cut the end that will go into the u channel to have short Tinners wings and a small drip tab to be bent down into the u channel. Cut the other end however is required to dump over the metal shingles. There should be a slight sideways slope towards the shingles.

clvr83 Said: U shape going horizontal, do you let it drain in between each one or send it out the ends?

Whoops :blush: I did not consider that these are "stacked". Yes that is different than just running a of 2 or 3 them across.

I think you'd still use the U Channel, but the corners would have to be turned and sealed, and yes, drain out the ends. Along with a head / sill flashing.

:) Oh well Like Old School said, with that set up, call Velux and pay for it

I did one like that before. the only way to do it is to take it apart from the top and then put it back together again. Not fun! One reason I like the Metro's (again) Anderson hasn't made skylights for a few years. Good luck getting anything to match up.

I think they are Anderson windows. The type with the rubber gasket going over whatever flashing is there. They added that top diverter after the leaks started, hoping it was a volume issue.

I was planning on replacing all the flashings, but I'm getting discouraged about getting these shingles apart, especially in a step-pattern. A guy on another forum basically said it wouldn't be fun, and might not work. Same thing here.

I'm going to walk the roof this week so I can get up close and personal with the problems.

Clover, the problem you are going to run into is that the skylight flashings from Velux or any of the other brands are not set up for the metal shingles like that. the step flashing on the sides are designed to go between the rows of shingles and not underneath the metal shingles. the shingles don't have any head lap. On a "ganged" system like that, you order the flashings with the lights and they are engineered to beat the band. Everything fits perfectly, and all of the pieces have little indentions in them so that there is no overlap and no high spots. Looking at the pictures, they just reused what they had and caulked the heck out of the sides. You could just get some of the wall flashings for the metal tiles and install it next to the skylight and counter-flash with a new Velux package. I would replace the flashings as they are old and a mess. There is a reason they are expensive, as the dies cost a lot of money to make.

U shape going horizontal, do you let it drain in between each one or send it out the ends?

It's just a U- shaped piece of flashing Clover.

Yeah it's hard to put some truth out there without sounding sarcastic, envious or bitter

I'll probably make an attempt

"We will bend our our own gutter in the middle for the ganged skylights"

I'm assuming gutter just means big flashing pieces. For a second I pictured something more complicated.

"the cheapest possible product is going on thousands of buildings as we speak."

I just ran a public radio ad for my business. I was thinking about revising it to say "this is a public service anouncement by Clover Roofing: Pole barn roofing is not a life time roof!"

Not sure if that would really help my business though, could be perceived wrong.

Don't be afraid of tearing this thing off CLOVER. Metal roof failures are the wave of the future. Hell I tore off one of my own!

Look at this way: The same people who cannot competently put on an asphalt shingle roof, are now promoting "Lifetime" metal roofs, selling and installing them.

Good Luck John Q. Public is all I can say

And of course, the cheapest possible product is going on thousands of buildings as we speak. There is a thriving market for defective coils out there I've been informed

Tough job to trying a new product on.

We will bend our our own gutter in the middle for the ganged skylights. Velux is extremely expensive and by doing it in the field, we don't have to make our best guess and then order.

They really get you with their trim coil prices....and you can't match their color. Usually it's not visible and "close" will work. If not, buy from Velux.

OS: The installer(contractor) was a client of his who he was helping with a divorce. They suggested the metal even though they had never installed it. Not that I can blame them for trying something new...
