pics from a job we have going

Hey Mike, no offence taken....This is exactly the same as a Steelox system. I think Steelox was an approved equal on this job but they are not a big player in this state. From what I have heard Steelox was the first manuf to use the basic details and many other manuf copied their lead. Many of the datails have been improved on over the years.

This roof is by Architectural Integrated Metals (AIM)

wywoody, There is 2" wide x 3/16" thick run of tape mastic between the panel and the valley flashing. As you can see the screws are centered in the tape mastic, 1" off the edge of the panel. The valley has an 18 ga back-up plate that the screws are screwed into so they are not going to back out.

I would think the kynar 500 paint would be the first part to fail...It has a 35 year warranty, and I would think that's about it's limit.

The jobs we did 19 years ago are still going strong with no leaks or problems. The washers, which are epdm are not exposed to sunlight and the butyl mastic is not exposed to sunlight either should last a long long time...I've seen tape mastic in panel seams 30 years old that looked brand new.

The screw heads are made of zinc aluminum "Zac" brand that does not rust.

Vaa, This is what's called a retro-fit system. We frame a sloped roof system over the existing flat roof. The big selling point of these roofs is that they are getting rid of their leaking flat roofs and replacing them with something that looks good and is a good roof. Most of the owners I deal with are fed up with leaking flat roofs.

Jed, I see that you are in Baton Rouge...The closest roof I have to you a scool in Mise MS, and another one in Laurel MS but I know there are many many roofs like this in your area. Check out some of the schools or armories in your area. You can find them and have a look.

McElroy has a screw that totally covers the rubber also

What is this guy doing? Looks like he killing someone with a screw gun :unsure:

Never used that detail. The preferred detail is a locking strip attached to the valley metal, the panels are then hooked on it. No exposed screws anywhere, and no exposed sealant.

That valley just don't look right to me. What happens when expansion starts doing it's work? Screws in the bottom of the valleys???? Not on my watch.

Triangle fasteners has come up with a new screw design called VRT(vibration resistence technology).

The valley plate is fixed at the eave and expands toward the ridge as do all the panels. This is a much stronger and weathertight installation method than cleated eaves and cleated valleys where the panels are fixed at the ridge. I've done lots of metal roofs both ways, and I prefer the panel fixed at the eaves.

In my area two libarys were roofed like this about 4 years ago with standing seam,they screwed the valleys and it looked horrible to me.Saturday they were tearing off the roof on one by my house,they were on z channel no dead valley though.They were screwing OSB back on a structure that the z is on 4 foot centers and installing durations.Yesterday on of the sobs was tearing the shingle felt and decking back off the front of the building,i suspect the parish engineer found something he didnt like.I was surprised to see them putting decking and shingles on a building that was built and designed for a metal roof.I reline builtin gutters on metal buildings all the time done with that same spec as that valley,i make good money off that spec as it dont last and steel will rot out where its in constant moisture as the bottom of that valley would be.
