The silicone will spread and adhere creating a seal.
How to install roof panels.
Now we can install our roof panels.
Beginning at the outside edge of your roof place each panel directly onto the purlins that are attached to the roof trusses.
Take your first panel and set it on the roof in the area that you will be placing them.
Step 3 drill the holes now you can take out your drill and drill bit and start drilling the needed holes.
If you feel the need for sealants lay a bead of 100 silicone or adhesive silicone before laying the sheet down and make sure the bead is towards the edge of the bottom sheet.
Along the fastening strip of the sl16 always use the pancake head fastener.
Do this until the entire roof is covered.
Make sure the panel is square to the eave of the roof so that all of panels installed afterwards are straight.
To install corrugated roofing start by cutting your panels to length with an angle grinder.
Continue adding panels until the roof is covered.
You will want to make sure that the curve on the panels is flush over the moldings you have just secured into place with your galvanized screws.
Metal roofing is also available in the form of shingles.
Screw the new panel in place as described.
On the roof lay out the locations of the stanchions that will support the solar panels.
Next put a screw into the fastening strip to keep it steady before installing the screws along the face.
Screw each stanchion through the roof and into a roof rafter.
Continue installing the metal panels making sure that the edges overlap at least 1 in 2 5 cm or as required with the adjacent panel.
Also be sure the stanchion flashing fits beneath the roof shingles to prevent leaks.
