The Benefits of a Metal Roof

Metal Roof

The benefits of a metal roof win many homeowners over when they are searching for alternative roof replacement options. From zinc to copper to tin, metal roofs are constructed using a wide variety of materials. Following are some reasons you should consider installing a metal roof on your home.


Metal roofs are expected to last for many decades. Warranties normally provide up to 50 years of coverage, although the length may be shortened to 30 years on metal roofs with a paint finish. Metal’s resilience outlasts that of asphalt shingles, which usually last 20 years at best.

Fire Resistance

Metal roofs are not susceptible to fire. Though some homeowners express concerns that lightning may be attracted to metal, this is easily prevented by grounding with a lightning rod. The roof itself is rated as Class A – the most fire resistant possible. However, if the metal is installed over wood, the rating may drop to a Class C. Still, the outer roof will not spontaneously combust if a nearby wildfire threatens the region.


Contrary to what many believe, metal roofs are extremely lightweight. If you are building a new construction and integrating this type of roof into the design, many contractors are able to lessen the number of roof support beams needed for safe installation.

Energy Efficiency

Metal roofs do not absorb heat from the sun. Instead, the metal surface reflects heat, minimizing cooling costs in the hot summer months by 10 to 25 percent.

Weather Resistance

The interlocking sheets are rated to withstand wind gusts of up to 140 miles per hour. No moisture is able to penetrate the outer surface, so rain cleanly drains off the roof and snow melts and disappears. The usual precipitation damage risk posing a threat to asphalt shingles has no power over metal roofs.

Increased Home Value

A combination of the lengthy warranty and the minimal need for maintenance make a metal roof replacement a valuable addition to the total home value. A metal roof can increase a home’s value by 1 to 6 percent.

Environmentally Friendly

Most metal roofing panels are compiled of recycled materials. Once the roof has served its purpose, the material is completely recyclable as well. This is a stark contrast to asphalt roofing waste, where tear-off roof installations alone generate 7 to 10 million tons of waste per year, not including the waste produced by manufacturers.

Installation Speed

Since this roofing type comes in large sheets, it is easy for skilled contractors to complete a metal roofing installation quickly. And since the panels weigh much less than asphalt shingles, no additional work is required to prepare the underlying structure before work begins.

Monetary Savings

The financial benefits are obvious. You won’t need to save for a new roof, and homeowners will spend less on repairs and maintenance than they would with an asphalt-shingled roof. They will pay less on air conditioning costs in the summer, but one other category also provides hefty cost savings: homeowner’s insurance. In some states, companies are willing to offer up to a 35 percent discount for homes with metal roofs.
