Spacing of furring strips for metal roof.

The thought process is the washer is flat this metal area is flat therefore it provides the best seal in the flat. Always place fasteners in the flat of the metal roofing. Or installing the new metal roofing over furring strips 1 x 3s or similar will raise the metal and provide a ventilating air pocket between layers. Place corner pieces where panels will meet bends at the edge of the roofing.

Correctly measure the spacing of furring strips for a metal roof to further decrease condensation. But roofers can install a vented metal roof that eliminates this potential problem. In most cases furring strips are 1 x 2 or 1 x 3 in size and can be applied both horizontally or vertically. If there are gaps around the roof penetration or valley points cut extra sections of furring to fit.

Add additional furring strips the final step is securing a secondary row of furring strips along the roof. If you re unfamiliar with what a furring strip is it s best described as a long slender strip that s constructed from either wood or metal. Make sure to consult local building codes before having a metal roof installed directly over old shingles. If there are gutters installed on the eaves the eave flashing should be installed to overhang the lip of the gutter by about 1 2 inch.

A metal roof must also allow for some overlap on each side of the panels which will reduce the effective width of the panel. Rafter spacing is based on the width of the metal roofing panels. We recommend installing furring strip 1x4 s down then applying single bubble wrap overtop of the strips and finally installing the metal roof. Metal furring strips come in two different styles.

Wider panels allow for greater spacing between rafters. Place it two feet apart from the first row.
