One question that we get asked as a professional roofer is how solar panels are actually installed on a roof. You might be researching the switch to solar and have questions of your own. We’ll cover some of the basics in the following article.
In most cases, modern solar panels do not harm your roof or leak if they are installed properly. The actual installation process itself differs greatly depending on what kind of roof you have. This will also most likely result in a big difference in the price – for example, installing panels on a flat roof is a far easier process than installing panels on a Spanish tile roof. Extra time is required to properly fix the panel structures to the roofing substructure in a way that won’t compromise the protection of the tiles. Flat roof installations are far more straight forward and can include fixing panels directly to the flat roof, then the areas are reinforced with the same proven techniques that allow a flat coated roof to remain waterproof. By intentionally building these areas up, they can easily provide lasting protection around the panels.
One advantage of solar panels is that your roof is constantly being assaulted by the UV rays and heat of the sun. Solar panels actually cover large portions of your roof, which will not be directly exposed to the sun after the panels are installed. Additionally, the sun is no longer directly beating down on your roof in these same areas. Instead the sunlight is reflected by the panels, which will often times make the rooms directly below the panels cooler regardless of insulation.
Your solar provider will also likely be working with a roofing contractor to ensure that the panels are installed correctly and will not be susceptible to leaking. This is a question you might ask your solar system provider however just to ensure that they are using a reputable company. Additionally, you want to make sure that any problems with your solar system that interacts with the roof is covered and will be repaired promptly.
