Installing Solar Panels on Various Roof Types Pt 2

In continuation of this week’s previous article, in order to anchor solar panel racking in the proper manner, installers would usually get rid of clay tiles from areas where they have to attach the racking feet to the roof. Flashing and metal hooks are drilled into the roof, after which the installers can proceed with sliding the tiles back into place – just above the solar mounting feet. According to the exact dimensions and shape of the tiles found on a given roof, an installer would have to make or buy unique-shaped hooks as well as flashing so that these parts fit properly underneath the tiles.

In some cases, they may simply use a new metal tile in place of the old version, basically combining the mounting foot, flashing, and tile into a single piece of equipment but this type can vary depending on the type and thickness of your tile.

Concrete and Slate Tile Roofs

Similar to clay tiles, concrete and slate tiles are typically removed and replaced in the installation process. Sometimes, workers will make a hole through the respective tiles themselves, although it is more common to get rid of and replace the tiles with a flashing and mounting foot due to the brittleness of concrete and slate.

Installing Solar Panels upon Other Kinds of Roof

Below, we will guide you through how solar panels are installed on other common roofing materials.

On Flat Rubber and Concrete Roofs

Multifamily houses often have either a flat rubber or a concrete roof. Solar panel systems can be installed effectively and safely on both of these. With a roof that is flat, panels have to be tilted in the direction of the sun for best production of energy, so a professional will have to place slanted metal racking in order to prop up the solar panels. Oftentimes, these systems do not even have to be affixed to the roof – rather than standard penetration mounting, several flat roof installations can make use of a ballast system that slanted roofs typically need. Simply put, ballast systems are a racking setup which holds the solar panels in place.

Just in case you have to drill into the flat roof in order to install the solar panels, do not worry; installation crew will ensure that the holes are kept as tiny as possible and also sealed properly, in order to avoid any damage or leaking.
