Roofing Screws In The Ridge Or Flat

Make sure to screw through closures.

Roofing screws in the ridge or flat.

Sharp point metal to wood siding screws. Screws in the flat nails on the ridge. 4 6 out of 5 stars 10. 250 brown 12 x 1 1 2 hex regrip sheet metal roof screw.

I strap all roofs with nothing less than 2 4 to help lock that roof in place. The idea being that the longer screws in the valley hold the sheet down and the shorter screws on the ridges keep the wind from picking up the sheet. The manufacturers recommend screws in the valley 3 per perling and shorter screws spaced 18 to 24 inches depends on the manufacturer on the ridges. Place large tab closure between the ridge cap and the roof panels.

On the ridges can distort the metal. Having done several metal roofs since then i would say if you are an amateur screw on the flat with 1 1 2 screws. Quite often the screws are over tightened or under tightened and when this happens it creates leak points. The main cause of a leaking roof on a diy metal roofing installation is incorrectly fastening the screws.

Screwing high on the rib is difficult for the amateur. Metal moves some heat cold expansion and makes a bigger hole in metal for a leak. If the screws are driven correctly fastening through either the valleys or the ridges of the roofing is considered acceptable in this country. Attach ridge cap to rib of roof panel with screws on every rib along both sides of rib.

Make sure and not get them too tight don t squish the rubber gasket just nice and snug. Valid arguments can be made for both preferences. Ridge cap should be end lapped 6 inches at each end.
