Who has the NRCA Roofing Manual(s)?


Recommended Posts

Thanks, Brandon.

No need for apologies. That was just one of those sites I couldn't navigate properly.

Checking the manuals, I discovered pretty much what Kurt mentioned. The specs and drawings are almost identical to what mfr's produce.

Good thing is the NRCA is an independent third party so their un-biased to any particular product.

Well, son of a @*!!.

The NRCA manual is no longer allowed to be viewed by non NRCA members: http://www.nrca.net/rp/technical/manual/manual.aspx

Does anyone have a diagram or good set of instructions showing how to properly weave a valley by chance?

There's this one from Carson Dunlop.

Thanks Jim,

On the 12" lap up past the center of the valley-- where are you supposed to measure from? I've always measured from about the top of the exposed part, but the measurement varies quite a bit depending on where you actually do measure.

Not that the location of the measurement mattered yesterday- they only lapped them up 3" or so in areas. (new roof).
