Metal Roof Strapping Or Not

Thanks for investigating metal.

Metal roof strapping or not.

There are two ways to do this put in firring nailing though nails are not used any more for this strips or purlins in steel frame construction on the roof to support it or place the metal roofing directly on a flat surface like foam insulation board or the roof sheathing with roof water barrier in the correct position in the layer. Supports restraint straps restraint strap are made from galvanised steel and have been designed to be used when connecting timber floor and roof systems to masonry walls ensuring fast and effective anchoring against uplifting forces like wind. Most products can or must be installed on solid deck. 1 some products can be installed on strapping.

Spacing of furring strips for metal roof when installing a metal roof over an existing roof insulate the spaces between the wood strips with rigid insulation to prevent condensation before. Designed to the building. The pre drilled holes allow various fixing points for horizontal and vertical application. By design some metal roofs must be installed over battens some must never be installed over battens and some can be installed over battens or solid decking.

There are several things to consider when determining whether or not to have your new metal roof installed over battens. However the problem would not have been completely solved unless you had also first installed vertical strapping from the eaves to the ridge so that water would have had channels to drain through.
