Metal Roof Furring Strip Spacing

The machinery will not cut panels shorter than 3.

Metal roof furring strip spacing.

Place it two feet apart from the first row. Correctly measure the spacing of furring strips for a metal roof to further decrease condensation. Twenty four inches is a common spacing of furring strips for a metal roof. If there are gaps around the roof penetration or valley points cut extra sections of furring to fit.

Screw fasten the purlins using fasteners directly screwed into the trusses or rafters. The final step is securing a secondary row of furring strips along the roof. So if your rafter length is 16 10 it can be cut. Peter the choice as to whether to use 1x or 2x for furring is probably best decided by how deep a ventilation cavity you need.

I put 2 x4 furring strips on the rafters to hold down cost. Metal roofing is 38 wide however the panels need to overlap and therefore the actual coverage of the classic panel is 36. This should then be followed up with galvanized steel hat channel preferred method or 1 x 2 furring strips. 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.

Edit answer for another 41 minute you need to check the installation instructions from the manufacturer depending on whether the purlins firring strips are 1x or 2x material and how wide thickness metal gage of roofing steel or aluminum type of seams design wind and snow loading whether designed to be walked on or not etc i have seen it vary from as little as 4 inches clear gap between firring strips on lightweight aluminum to as much as 4 feet on very heavy gage steel. If you opt to put the metal roof atop current roof shingles it needs to be done in combination with a synthetic underlayment recommended. Both have stronger holding for fasteners than the sips sheathing. However you can cut the panels with tin snips if you need pieces shorter than 3.

If you are using 5 8 sheathing above you can go to 24 oc furring without using h clips. Do i need to do this. When finished there should be a row of furring strips stretching from one end to another with the top edge aligned at the peak. Someone told me that i had to put felt paper on the furring strips to hold down condensation and that it was also required.

I built a 12 x20 flat roof shed for storage.
