Sorry, hit the return key by accident before I was finished! I'm a home owner and I feel I'm not getting a good installation on our metal roof. I'm afraid we will void our warranty due to improper installation. It doesn't look right to me, but I don't have the technical background in metal roofing to call the contractor on his work. To make it easy, I posted some photos of the work I'm concerned with on the web. I am most concerned about the flashing or lack of around the skylights and vents. The two skylights are 2'x2' self flashing, but It doesn't seem right to run the roof metal within an inch or two of the skylight edge and then goop huge amounts of calk around the edge. The calk is maybe an inch or more deep in the channels. Here's the URL: If you can have someone take a glance at these and give me some feedback, I'd be most appreciative. Thanks, Tim Catlin 928-525-2581

Well, this is what I got back from the manufacturer: ***** I offer you the following information: I would suggest that you contact either another roofer and/or a roofing consultant to take a look at the job. At this pint it is really between you and the contractor/installer. Our warranty only covers for coating (paint and corrosion). I would also suggest that you visit the www.ascbp.com website and look under light gauge metals and you will find an installation guide on Strata Rib. This will also help you. ******* Well, if I knew about metal roofing and could read plans then I would be ok, but this is not the case. I just need some basic guidelines on standard flashing procedure and standard code for skylights and dormers. I feel somewhat abandoned by the manufacturer. Can anyone give me the slightest hint whether this contractor has a clue? I'm seriously considering hiring another contractor to finish this job. thanks, Tim

Thanks Todd for leaving this one to me. Anyways the self flashing skylight I know of is typically for an ahingle roof and not metal and typically they are designed to last now longer. Most metal systems require that the metal be bent up agaist the skylight curb and under the couterflashing of the skylight. I would say that you have an issue to discuss with the contrator. I would get his opinion in writing, download the asc specs to review and if there is a problem then hold back monies until it is resolved. If you can't agree who is right, then inform the contractor in writing that you are going to hire a local roofing or engineering comsultant to review the instalation to the specification. Each party be prepared to pay if they are wrong. If you are right, then give him the opportunity to correct the mistakes and deduct the inspection fees.

Thanks Allan, I've glanced at the ASC specs and it seems to only deal with curb mounted models as far as I can tell. so perhaps the selection of the skylight was an issue to beging with? This is a model made by Solar Industries Inc. and in laymens terms is kind of like setting a square wide brim hat on the roof sheeting. The problem is that I'm not really understanding the ASC specs and getting no help from them at all. I can't really demand that the skylights be installed correctly if I can't describe what exactly that method should be. ...or was the selection (by the contractor) the wrong type of skylight for a metal roof? I'm totally lost here and not sure how to address this. We bought all the materials, don't have a contract, and haven't paid out a dime to the contractor yet. Tim

Hi Allan! Actually, Tim had emailed direct to me and I have been trying to provide some help that way as well.

Tim, Frankly, I am not sure I would have ever suggested installing skylights on what appears to be a pretty low pitch roof with an R Panel roof being installed. I am not sure what minimum roof pitch ASC requires for Strata Rib. However, hopefully it is in their specifications. Can you verify that your roof has that much pitch? Ultimately, for the skylights, underlayment (of which you said you have none) should have been brought up around the curbs and sealed to them. I also would have worked in extra underlayment on the top side of the skylights which then would also direct water down the sides of the skylight, should any water get under the roofing. For an underlayment around the skylights, I would suggest a self-adhering ice and watershield type of product for extra ssafety. There then needs to be a custom flashing surrounding the skylight curb. It should be formed from the metal matching the roofing. It needs to go up the sides of the skylight and underneath the outer rim of the window part. On the bottom of the skylights, this metal should be positioned high enough so that it extends out on top of the roofing, with a closed hem on the bottom. It should extend out 6" or so. Use sealant or a foam closure strip between the roofing and the flashing. On the sides, you can do this same thing or the flashing can go against the roof decking, underneath the roof panels. If it goes undneath, it needs to then come back out on top of the bottom flashing which would have to be extended beyond the sides of the roof window. This can get tricky due to the R Panel configuration. On the top, the flashing should extend above the window by 18" or so, eventually ending up underneath an upper level layer of underlayment. The roofing is then brought down over this flashing and sealed. I hope this helps some. The wall flashings should be handled similarly. If possible, the wood siding should be removed so the flashing can go beneath it. If not, perhaps you can saw cut the siding and insert the flashing into it about 4" above the roof level. The other option would be to screw the flashing to the siding and seal it. Again, through, underlayment should have also been brought up the wall and sealed before any of this happens. Again, I hope this helps some. Best Regards.

Just got off the phone with the skylight manufacturer and he said that the model the contractor installed is NOT designed for metal roofing and that I should have their curb mounted model. So his opinion is that these skylights need to come out. I'll check the roof pitch against the ASC specs. This just keeps getting better! Thanks so much for all the help. Tim
