The condition of your roof is of utmost importance when installing solar panels. Installing panels on an old, worn roof could result in potential damage to your structure. This will also mean that your panels will likely outlive your roof, resulting in a need to remove the panels, install a new roof, and get them re-installed - a pricey endeavor! Starting with a strong structure is critical to supporting your new solar system. Solar can be installed on all types of roofing, but metal is one of the best choices around!
Metal roofs have longer life spans than asphalt shingles, in some cases coming with a 40 year warranty. Asphalt shingle roofing usually lasts about 20-25 years. Solar systems generally have a lifespan of 30-40 years, so it makes sense to match up the life span of your roof with your panels.
We highly recommend having a roofer inspect your home to determine the life left in your current roof. It may make sense to re-roof your home at the same time as installing the solar panels if your current roof won't outlast the solar system. Racking is easily installed on metal roofs, whether corrugated or standing seam.
In addition to being a strong structural support with a long life span, metal roofs can also save on energy costs. A cool metal roof can reduce cooling costs by 40%! Combine that with your solar savings, and you will have an incredible amount of energy savings.
