The Benefits Of Metal Roofing

Metal roofing is not the least expensive roofing on the market, that would be asphalt shingles. On the other hand, when determining what the least-expensive roofing material is, most people consider installation cost as the sole determining factor. When you add in energy, replacement, and maintenance costs, metal roofing becomes a more attractive choice than asphalt shingles. You can, in fact, save money over the life of your roof by choosing a metal roof instead of asphalt shingles. 


Most asphalt shingles will last between 15-20 years no matter what the warranty says. While this may seem like a long time, a twenty-year lifespan pales in comparison to the fifty-year life span of galvanized steel roofing, or the hundred-years-or-more lifespan of copper roofing. You will have to replace your asphalt shingles twice before you have to replace a metal roof even once. Because metal roofing is not two times more expensive than asphalt shingles, once you add in replacement costs, asphalt roofing is more expensive than metal roofing based on replacement costs alone. 

Repair Costs

One of the biggest threats to asphalt roofing is the sun. The sun will bake the residual moisture out of the asphalt tar in the shingle, which will make the shingle shrink and curl as it becomes brittle and prone to cracking. To protect the asphalt tar, manufacturers will coat the shingle with a layer of protective granules. However, hail can scrape these granules away and because hail can fall at any point, your twenty-year shingles can lose their layer of protective granules after one intense hail storm even a week after installation. By way of contrast, metal panels will not be damaged by the sun and while large hailstones may dent the metal, you won't have to worry about leaks. Thus, because metal is more durable than asphalt tar, the repair costs associated with a metal roof are much lower as compared to an asphalt-shingle roof. 

Energy Costs

Asphalt shingles tend to absorb the sun's energy and convert it to heat. As your shingles heat up, they can heat up the interior of your home. By way of contrast, metal is naturally reflective and when treated with an emissive coating, a metal roof can reduce your cooling costs by up to 40%

As the above discussion should indicate, you should consider much more than initial costs when choosing roofing for your home. When you consider the money you save on replacement, repair, and energy costs with metal roofing, it is easy to see why it is a better choice than asphalt shingles.
