Most roofs are the ideal places to install solar panels because it receives sunlight constantly throughout the day. However, what most homeowners don't know is that their homes may not be structurally strong enough to bear the excessive load of solar panels. That's the reason why the installation of solar panels in most cases damages the roofing shingles. In extreme cases, it can even break down the wooden decking that can result in the sagging of your roofing system. No doubt, solar panels can help you save some serious money on your energy expenses, but if possible try to choose some other areas outside your house for installation.
