How to Install Metal Roofing Over Shingles or an Existing Metal Roof

Installing metal roofing over existing shingles is an excellent way for contractors to help building owners not only maximize the longevity of their new roof but also to save on roof tear off expenses. There are billions of square feet of roofing on commercial and industrial buildings in the United States. Much of it in need of roofing repair as most contractors know and see every day.

Why Install Metal Roofing Over Existing Shingles?

ShingleRecover3Shingles might be an inexpensive roofing material, but they require a maintenance and need to be replaced pretty frequently. Unfortunately, shingles are typically not recycled, and because waste disposal companies and landfills receive so many shingles, they can charge a large fee to accept them.

Metal roofing offers building owners a way out of the shingle replacement cycle.

Metal roofing requires a more significant up-front cost than new shingles, but metal roofing can last 50+ years with minimal maintenance. A metal roof can also be used to add curb appeal to a building because they come in a vast variety of styles and colors.

Longevity and aesthetics aside, metal roofing is made from recycled material and is 100% recyclable at the end of its lifespan.

Installing a metal roof over existing shingles also means that any shingle tear off expenses, including disposal fees, are avoided entirely. And you get all the benefits of a metal roof.

How to Install Metal Roofing Over Existing Metal Roofs

McElroy Metal has developed several roof recover systems that contractors can also install over worn-out metal roofs.

For existing metal roofs that need to be repaired or replaced, our frameless 238T Metal-Over-Metal Recover System is our contractor customer's favorite recover solution. This roof recover system is most often installed over existing thru-fastened panels. Because of the frameless design, material and labor costs are greatly reduced which allows contractors to offer this option to their customers at a price level competitive with single-ply roofing.

Another benefit of our recover systems is that they are considered a roof alteration and does not need to comply with current IECC requirements. Removing and replacing a roof requires that the building be brought up to current insulation requirements. This alone adds significant cost to a roof replacement project.

Finally, McElroy Metal’s 238T Metal-Over-Metal Recover System includes one more feature that makes it a tremendous value: a symmetrical standing seam. Symmetrical standing seam roof panels can be removed and replaced individually if damage ever occurs or if alterations such as curbs need to be added at a later date. This feature comes in handy for buyers in storm and hail prone areas.
