Foam insulation strips come with every roofing order. They are to be placed along the top edge of the panels where the cap covers. Place the sticky side of the insulation strip down on the roof panel, and screw the top cap into place.
This prevents wind from driving water onto the top seam and bringing moisture into your home.

Is It A Good Idea
As with most things, this depends on the circumstances, including the type of structure and your overall goals. Because you dont have to strip away the existing roofing material, metal roofs can provide cost savings. They can also provide additional insulation above a house to prevent cold and warm air from escaping. Metal roofs also reflect heat away from their surfaces instead of absorbing it. This prevents the extra insulation from your underlying shingle roof from acting as a heat trap.
With that said, there are a few considerations you need to make before deciding to install a metal roof. These include:
- If your existing shingle roof has any leaks, you will need to inspect for rotting sheeting or rafters and fix these potential issues before installing the new roof.
- You need to check with your local HOA, zoning and building departments to make sure they dont forbid metal-over-shingle installations.
- If the existing roofs weight has promoted any structural issues such as buckled trusses or sagging decking, this will need to be repaired first.
Its also usually best to consider adding some kind of underlayment between the shingles and new roof to keep granules from contacting the metal and promoting corrosion.
