Cost-Effective Performance: Slate Vs. Galvanized Steel Roofing

A roof can do much more than keep the rain out. Thus, when you purchase a roof, you should look beyond the initial cost and try to find the best value for your money. You might pay more for a material such as slate or metal, but if you get more value for your money, the higher installation cost is worth it. 

Longevity as a Function of Cost

The longer your roof lasts, the less you have to worry about replacement costs. Slate roofs will last for between 50-200 years. That's quite the range. To pick a long-lasting slate, you need to pay attention to whether it is hard or soft slate as well as the quarry it comes from. The price of slate will depend on quality, the thickness of the tiles you purchase, and availability, but you can expect to pay up to $18,000 to cover a 1,256-square-foot roof. As a point of fact, thicker tiles will weather better than thin ones.

A galvanized steel roof will last for at least 60 years and comes at a cost of up to $12,000. Due to the fact that either roofing material can virtually eliminate your need for a replacement during your lifetime, galvanized steel is the better value. 


Slate is one of the heaviest roofing materials on the market. Slate is so heavy, in fact, that you will likely need to reinforce your home's frame in order to support the weight of slate. Weight becomes even more of a concern if you live in a snowy climate. Because slate can break if you don't walk on it carefully, shoveling snow off your roof to mitigate the risk of roof collapse becomes a real challenge. 

In contrast, metal roofing is one of the lightest roofing materials on the market. Thus, whether you are replacing an existing roof or putting a roof on a newly built home, you should not have to worry that your roof might be too heavy. Furthermore, metal's low-friction surface will allow snow to slough right off of your roof. Thus, you should not have to worry about your roof collapsing no matter how much snow falls. 

Slate is a beautiful roofing material, but it is not right for everyone. If you live in a snowy climate, you can make your roof structure bombproof, or you can consider using a lighter material. For those who don't have to worry about a roof collapse due to snowy conditions, metal roofing is an excellent choice. To find out more about roofing, speak with a business like Davis Roofing Co.
