Installing a metal roof over your existing asphalt shingles is a great idea if you’re looking for more convenient and durability. There are a few notable benefits to this common method of installation, and it can save a lot of time and money in the process. After all, the money you would normally spend on removing and disposing of old asphalt shingles could be used to purchase high quality metal roofing.
If you’re concerned homeowner looking to learn more about your metal roofing and installation methods, here are a few of the advantages of this approach:
Added Layer of Defense
One way of getting this job done involves running a new underlayment to completely cover the existing roof, and then placing the metal roof on top of that. This doesn’t just provide a convenient buffer between layers; it acts as a second line of defense if water manages to make its way under the metal layer
Increased Energy Efficiency
Installing a metal roof over asphalt shingles also helps increase energy efficiency. This is particularly good news for the R-Value or thermal resistance of your home. The higher this capacity is the more effective your insulating power will be.
As efficiency goes up, waste goes down. Letting an old roof stay in place will keep you from needing to fill up nearby landfills with old asphalt shingle materials. It’s hard to argue with the combination of saving money and being considerate to the environment.
As long as there are no signs of leaks or existing weight issues, placing a new metal roof over shingles is a viable and cost-effective option. Of course, every roof should be evaluated on an individual basis. Contact Superior Steel Roofing for professional metal roofing contractors in the Southern Ontario region.
