i’ve been looking into redoing my roof with 5v crimp and it’s 12$ each at my local home depot and lowes for a 2x8 sheet. i’m going to need around 50ish
does anyone know a cheaper place to buy from in the tampa bay area? that will sell to a non contractor?
Please do not take this response the wrong way but, a job like that should be done by a professional that understands how to do the job properly. 5v is not as easy as shingles. Best advise i can give you is to find a pro to handle the work. Not saying you cant do the work im just saying there is alot more that goes into a 5v roof than standard shingles.
Guido,
Why don’t you tell him how to install metal roofing so it doesn’t oil-can?
Are ventilation requirements different for metal roofs? I’ve eyeballed a lot of metal roofs since I found this forum and most seem to be unventilated. I do recall seeing a lot of them installed over “open sheathing” .
hello iopsailer,
yeah most standin seam metal roof panels oil can.
they make a special standin seam panel that has 1/2" brakes all the way across it.
but some dont think it looks as good. and its a bitch to lay.
as far as 5vcrimp goes, i put on what the manufacter gives me.
just screw it on, didnt know of a certain way to install it as not to oil can.
installin metal over bear wood, sounds like north florida, georgia, or alabama. not big on underlayment in those parts.
im ok with that, only the metal is the roof.
i like underlayment for the better work surface it provides.
better that workin off plywood.
There are a couple of things that can cause oil canning. First and foremost is an uneven substrate. Second, you can oil can the metal panels by over-driving your fasteners, especially if you are using clips. Third, kinking the panels prior to installation. Fourth, poor job of roll forming…Those are the main ways I know of…Anyone else think of other ways that I forgot to mention?
Oh yeah, I’ve not seen anyone do this, but I suppose if you “fix” the top and bottom of the panels instead of “floating” one end, that would likely cause the panels to oil-can.
Also, you definitely want to use at a minimum 30# felt beneath the metal panels. This is especially true if you are installing the panels over treated wood.
