Mod Bit on a mfg hm

[Denray]

Think it's OK for a mod bit to be over the metal skin of this mfg home? Edges seem to want to come up here and there.

Mod bit needs a rigid base. That tin bends with the wind and when someone walks on it.

Did you notice any creases on it?

Nothing wrong with mod bit over metal. But you have to prep the metal properly or the mod bit won't stick - just like flashing in a new install.

It looks like there was a problem with prep.

Thanks guys. Never seen it done on one of these. I'll bring up the prep stuff in the report Jim. No creases. I no walk those kind of roofs, just move my ladder around 6 or so times.

I think it is a practical way to extend the life of the home for a few more years.

It works. And I agree, no need to walk it.

Look at the crap on the roof next door. [:-party]

I would like to add, for the benefit of anyone contemplating such a roof. Spend just a few more bucks. Add drip edge flashing and gutters before applying the torch-on membrane.

Jim's right. Won't stick if it's not double primed.

Is that metal aluminum or 26 gauge galvanized? If it's aluminum, it'll usually come loose even with primer; the aluminum moves around too much.

There's no way anyone's going to get it to stick now, anyway.

It might not be a bad idea to stitch it in place with a termination strip and call it a day.
