3 install 1x4 purlins down over the shingles before installing the metal roof the third way to install a metal roof over shingles is by applying 1x4 purlins over the shingle roof.
Installing steel roof panels.
Cut the first rib off leaving of rib on the first roof sheet of roof steel.
Lay down the first roof steel panel squaring it with the mason line.
You are essentially sealing off the metal roof with this flashing and you need to make sure that is securely fastened.
Make sure the panel is square to the eave of the roof so that all of panels installed afterwards are straight.
Always begin working at the point with the longest peak to eave distance.
As long as the plywood under the shingle roof is in good condition this way can provide many benefits.
In a standing seam roof long single panels run vertically all the way from the eave to the ridge.
Next you are ready to install the metal roof.
Be sure the larger edge is laid so that the small edge of the next panel will overlap it.
When you decide to install corrugated metal roofing you just need to make sure that you have the right materials.
Now we can install our roof panels.
The roof panels are installed similar to the wall panels in layout.
Take care the first piece is aligned precisely perpendicular square to the edge.
The eave flashing or edging is just the steel metal strips used to cover the entire perimeter of the roof.
Moreover a corrugated metal roof is highly durable and will last for decades.
Install the roofing screws vertically along each rib in the panel.
Using screws fasten roof at top and bottom of the sheet in the flat next to each rib.
Along the fastening strip of the sl16 always use the pancake head fastener.
This is by far the most common way to install a metal roof.
Next put a screw into the fastening strip to keep it steady before installing the screws along the face.
Corrugated metal roofing can be a convenient and relatively affordable way to provide protection without the need to install metal shingles.
You can use 1 inch nails for the installation of eave flashing.
Align the first metal roofing panel so that it overlaps the edging by 1 2 to 3 4 of an inch and is square to the roof line.
