When you are building a house or even re-roofing the house, you can use insulated roof panels to make the home more energy efficient. There are three types of roof panels. They are the tongue and groove roof panels, foam roof panels and insulated roof panels. The panels are lightweight and water resistant. The roofing panels generally come in 4×10 and 4×8 with 2’s being used for connecting spines.
The insulation can be any thickness depending on what you need. For re-roofing, the sandwich roof panels are the best to use. Instead of using plain plywood on a roof, you can replace it with the sandwich wood panels and add to the energy efficiency of the home.
- How to Install Insulated Roof Panels
Once you have removed the old shingles and tarpaper, you will see the plywood that is on the roof now. You can safely remove the plywood so that you can add the sandwiched roof panels. Do not remove every panel of plywood. you want something to stand on while working.
Remove one or two pieces at a time. This way, you will also be able to see the rafters better when installing the new roof panels if you are able to stand on adjoining plywood roof decking.
After you have the first two sections of plywood removed, bring up one sandwiched roof panel and use you levels and tools to nail down the first piece. Continue until you have replaced all sections on the roof. Use the tongue and groove roof panels for easier installation. The nail size you use will be determined by the manufacturer requirements.
After the panels are up, you need to fill in all the joints with the foam. This is important to do before putting the tarpaper over the roof panels. Use the foam that is recommended by the manufacturer. You also have to fill the nail holes with foam. This is to prevent any heat loss.
Sometimes it is easier to lift the insulated roof panels to the roof with a crane. They are lightweight, but the size and thickness can make it tricky to do this yourself. If you are going to lift them yourself with the help of another person, use scaffolding for the task.
The peak of the roof is a beveled joint. This is in most cases. Some cases may change this. Flat roofs, however do not have a peak and will be laid out from eave to eave.
Cut the eave edges prior to installing the roof panels. This will make it easier to place the panels correctly once they are lifted onto the roof. The eaves do have to be perfect when you are using insulated roof panels.
If you are building a new home and using insulated wall panels, you are going to follow steps for installing the wall and the roof. This will be slightly different than installing just the new roof.
Insulated roof panels will cut heating and cooling costs. This is a more expensive project, but it does save money over time. It is more energy efficient than using radiant barrier treatments. The sandwich insulated roof panels can be used on garages and homes, but it is not recommended for other types of buildings.
