Skylights In A Metal Roof


So I cant help but notice lots of houses with skylights have mismatched shingles around them. Probably because they end up with leaks like they all seem to do.

Is it just me or does it seem like a bad idea to have skylights on a 100 year roof? That would be a costly repair if it needs to be replaced. Ill probably have one to do next summer with 1-3 skylights.

Or is there some alternative like a frame you put in and if there is ever a problem with it you can just pop in a new one?

Re: Skylights In A Metal Roof


Love to hear other opinions but I cannot see the issue other then the glass failure .Seems to me if flashed properly should be a no issue .

Re: Skylights In A Metal Roof


If you remember that water runs down hill and flashing accordingly , it is not really to hard to have a leak proof install.

Re: Skylights In A Metal Roof


We are currently working on a home remodel that will have 50 skylights and a standing seam metal roof. These will all be on 2x6 curbs only to keep all of the flashings looking consistent. Velux makes some great skylights, that installed properly should not leak.

Re: Skylights In A Metal Roof


Do like Warren is doing, curb mounts; that's the frame that you mentioned in the OP. That way if the skylight leaks it's easy to replace (as long as you can get one that matches the curb )

Re: Skylights In A Metal Roof


Im not so worried about the flashing leaking as I would about an issue with the unit it self needing to be replaced. Mine started to leak around the glass.

Re: Skylights In A Metal Roof


I made my living doing commercial industrial metal buildings and have installed acres of metal roofs. Yeah you can do it, but my first recommendation would always be to eliminate any unnecessary penetrations in a metal roof.

Sounds like this is an existing metal roof rather than new which makes this tougher yet. What is the profile of the roof panel?

I have never once had a problem with a skylight that I have installed.

I would also imagine on a 100 year roof the flashing is also 100 year flashing

Velux makes them. They have been around for many years. I talked to our salesman last week about these and while cool, he has yet to sell one.

I used to build Butlers, and I used to agree. Then years later I was a superintendent on a bunch of commercial work where curb mounted skylights went into an existing metal roof. The work was perfect and have never leaked. I asked the tinney what he did, and he just showed me the cut sheet by the metal roof and the window manufactuter, and he followed those to a T. You may always have an issue with screws loosening, but generally it should work.

That said, I'd walk up to skylights when I worked for the Butler manufacturer and I couldn't believe the mess. And also I'll try to be nice here, but I was once one of them. A lot of those metal building hands are the roughest and most drug infested crews I've been around. And I've worked all over. I really wonder if a lot of them just did not have the ability or the temperment to figure out the directions or the brake shapes.

My experience with workmen and workmanship are nothing like this. We always had good people that did good work or they weren't around long. Did random drug testing too.

Re: Skylights In A Metal Roof


For metal roofs, I like curbs. It just seems like the best way to go.

What I have been seeing is low quality metal roof installations. Mostly on re-roofs. So many guys are putting steel directly over the shingles. When you have an existing skylight, they are running into an issue. I have seen them siliconed in, more than once. Of course these are guys that aren't the highest quality individuals, to begin with.

For your skylight, leaking around the glass, I haven't seen one that leaks around the glass, but I imagine it does happen. If it is a Velux brand, you should be able to find one that will fit in the existing opening.
Even if it's older. I know there used to be the Roto brand. Then it was bought out by Andersen. And I'm pretty sure the Andersen brand became Velux. They look almost identical.

They did pre-employment drug testing.

And the buildings ended up great, as long as they didn't have to vary from the pre-engineered package.

I don't have any other explanation.
