Solar panels usually weigh around 40 pounds each. Is your roof prepared to bear the additional weight?
Your roof’s eligibility to hold solar panels depends on several factors, such as the material. It must have the best type for installation, or you might have to replace it entirely.
After all, the best roof for solar panels is strong enough to carry a whole structure. It must also last as long as your new renewable energy system.
Not sure what to look for in your solar panel roof? Keep on reading to see the best materials for installation:
Asphalt Shingles
Asphalt shingles are the most common roofing material in the United States. Fortunately, this roof type is suitable for solar panel installation.
The primary reasons most homeowners choose asphalt shingles are because they’re durable and long-lasting. Asphalt is also cheap, making them easier to replace after reaching the end of its lifespan.
Tiles
Tiles are also a decent candidate for installing roof solar panels. They’re more durable and have a longer lifespan.
However, installing solar panels on a tiled roof is more expensive. It requires additional precautions and considerations.
For one, the contractor must install the panels properly to prevent breakage. There’s also a proper procedure for fastening the feet to the roof.
Metal Standing Seam
Metal standing seam is the best type of roof for solar panels. Installation is easier and cheaper.
Contractors can attach the solar panels to the seams, removing the need for drilling holes. Metal is durable, too, as long as it has enough gauge for the roofing clamps.
Tar and Gravel
Tar and gravel are the common materials for flat roofs. You can put solar panels on them as long as they can handle the additional load.
You need only buy additional brackets. The solar panels should tilt at a 30-degree angle for optimum sunlight collecting and energy production.
Best to Avoid: Wood
Wood roofs are brittle. It’s hard for contractors to stand in them, making installation a lot harder than it should be.
Some states won’t even allow you to install solar panels on wood because it’s a fire hazard. In this case, is solar worth it? It’s much better to have your roof replaced with a more suitable material.
A Roof in Good Condition
Ultimately, the best roof for solar panels is still one that’s in good condition. No matter what type of material you get, it won’t matter if it’s no longer durable enough to carry the extra load.
In general, consider getting a new roof or a roof repair if your current one is nearing its end of life. Shingles last around 20 to 25 years, while tiles can go beyond 50 years.
