Can a Metal Roof be Installed Over Shingles?

can a metal roof be installed over shingles

Installing commercial metal roofing can be an excellent way to protect your commercial building and prevent water damage. However, there are many misconceptions surrounding metal roofing. Find out how you can install metal roofing over shingles and why you should consider this installation option for your business. Learn the signs of a commercial roof that needs repairs and compare common roofing options.

Installing a Metal Roof

A professional roofing company can easily install a metal roofing on any sloped roof. For most buildings, you won’t have to remove your old, worn-out shingles to enjoy a full metal roof. Choose a professional roofing company that can install a vented metal roof and you can enjoy hassle-free roofing for years to come.

Check with a local roofing company and ask about building codes in your area. Some local building codes don’t allow a new roof to be installed without a complete tear-off of the old roof. The concern with installing a metal roof over old shingles is that moisture may be trapped in between the layers. A professional roofing team can prevent this by using furring strips to create air pockets and a ventilation system between the layers.

Metal roofing is less forgiving than shingles. Asphalt shingle roofing is relatively easy for an inexperienced team to put in place and nail down. Sizing, cutting and installing metal roofing is far more precise. An improperly cut sheet of metal roofing is unusable and a costly mistake. Choose a reliable, experienced team to keep your project moving forward and avoid expensive mistakes.

Signs You Need a New Roof

Inspect your roof to see if it’s time to receive a completely new roof. If you have a sloped roof, it typically uses asphalt shingles or metal to provide a protective barrier. Asphalt shingles wear out quickly and can cause your roof to leak. Here are common signs that you need to replace your shingled commercial roof:

  • Cracked shingles
  • Missing gravel
  • Bowing areas of your roof
  • A shingled roof over 15 years old

When in doubt, have a roofing company inspect your current roof. Don’t wait until your roof leaks and damages the interior of your business before requesting emergency roofing repairs. Proper maintenance and foresight can reduce the cost of your roofing project and protect your business.

If you already have a metal roof, it’s still important to inspect it occasionally. Improper installation can cause leaks and reduce the lifespan of your metal roof. Even if it was perfectly installed, an older metal roof may be forming rust and reaching the end of its lifetime.

Benefits of Metal Roofing

Work with a premier metal roofing company and enjoy a replacement roof that can last at least 30 years. Some commercial roofs are designed to last up to 50 years with proper installation. While the upfront cost of a metal roof is slightly higher than asphalt shingles, it quickly pays for itself with reduced maintenance and extended lifespan.

A metal roof doesn’t require the same amount of pitch as a shingled roof. This means that a slow, gradual sloped roof will last longer and keep your building protected better with metal. With proper maintenance, you can enjoy years of long-lasting roofing with virtually any roof slope and design.
