I have removed all the old shingles from the roof boards not plywood the roof is in great shape and have installed an ice shield over the roof.
Installing metal roof battens.
Take your first sheet of metal and place it on the roof so that it overhangs the edge at least 3 4 in 1 9 cm.
For example metal roofing will be attached to special metal roof battens.
Add the metal panels.
And then you put down horizontal battens for the roof panel attachment.
Not all metal roofs can be installed over battens like that.
Can i install the metal roof over the ice shield or do i need the 1 x 4 battens every 2 feet as well it s a low slope roof thus the ice shield for extra protection.
The batten seams are covered with batten joint and then the metal sheets are attached at specific intervals.
How you install battens can affect the drainage efficiency.
For example horizontal battens run.
This involves putting down vertical battens first attaching them through the roof deck to the rafters.
Take care the first piece is aligned precisely perpendicular square to the edge.
The spacing of the roof battening highly depends on the type of exterior roofing material that is going to be used.
Basically all metal roofs that can be installed on battens can also be installed on solid decking with underlayment.
Experienced do it yourselfers can use a nail gun with 8d nail clips instead of a hammer and nails.
Whereas many older metal roofs or metal roofs on larger buildings have been successfully installed over battens rather than solid decking it is the clear preference for residential applications that metal roofing always be installed over solid decking to avoid dangerous and damaging condensation issues.
Before even considering it make sure the product you re installing is approved by its manufacturer for that type of application.
Battens elevate the roof tile off the roof deck and this ensures that water drains off the roof.
Use a tool belt that has a hammer loop to hold nails a measuring tape chalk line and a hammer when installing the wood.
