As local roofing contractors, a big part of our day is spent fixing broken roofs. Sometimes a windstorm tears out lots of shingles. Other times a tree collapses and puts a huge hole right through the roof. Still other times water damage or pests have slowly caused the roof structure to become unsafe and unstable. It’s all in a day’s work for us.
But if you’re in that situation, as a business or homeowner, you have a decision to make. If you’ve got an old roof made from asphalt shingles that becomes trashed, are you obliged to stick with the same material? Not necessarily. As a matter of fact, metal roofing has become a highly popular option for consumers. Better yet, it’s become standard operating procedure to just install a new metal roof on top of the old roofing structure. This procedure is actually more efficient, more cost-effective, and is a better decision in the long term. Read on, and we’ll explain why.
- Maybe you’re thinking, “You can’t put a metal roof on top of asphalt, the whole thing will collapse! Are you nuts?!” Here’s the thing. The metal materials are actually far lighter than what was previously used. Steel shingles are only about 1/4th of the weight of asphalt, while aluminum shingles are just 1/8th of the weight. Odds are that more weight was added to the roof when the final layer of asphalt was originally installed.
- But now you might assume that these superlight metal shingles have all the structural integrity of tissue paper. Not so much! When metal roofing is properly installed, it becomes far more damage resistant than traditional building materials. During a heavy windstorm, asphalt shingles or other parts of the roof can be torn off and blown miles away. With metal roofing, that becomes a non-issue.
- We understand wanting the best bang for your buck. When a metal roof is installed on top of a damaged pre-existing roof, it’s actually cheaper than the alternative. Consider that otherwise, you’d need to spend money unnecessarily to tear out shingles and throw them into a landfill instead of covering them up. Plus, when you layer the metal over the asphalt, you’re creating more thermal resistance in the roof assembly. That equals more energy efficiency and lower heating and cooling bills.
- There are some people who don’t entirely trust newer technologies and prefer to stick with tried and true methods. We get that, but maybe it will make you feel better to learn that the ancient Romans and other civilizations used copper as roofing materials. Copper and other metals were constructed and went onto the rooftops of churches, homes, schools, and commercial buildings. Hundreds of years later, they’re still structurally sound.
If enough damage occurs on your roof, it might make more sense to have the roof re-installed instead of simply repaired. When that happens, it’s often covered by your insurance company, and the reasons for using metal for the new roof can be awfully compelling.
