Installing solar panels on tile and shingle roofs

Many properties have tiled roofs, which may seem like a barrier to installing solar. However, solar racking companies and installers have crafted many intelligent and safe ways to make putting solar panels on a tiled or shingled roof easy.

Can you install solar panels on asphalt shingle roofs?

Asphalt is perhaps the most popular roof material – as such, asphalt shingle solar panel installations are common and straightforward. Installers will drill studs into your roof and attach panel mounts at those locations. To finish the job, the space around the brackets is sealed and surrounded with a flashing – a metal plate used to prevent water infiltration.

Can you install solar panels on clay tile roofs?

Traditional Spanish tile roofs are made from clay tiles – this can be a pricey material to install solar panels on, given the extra labor required, but it's still very doable for solar installers.

Unlike traditional asphalt roofing, clay tiles are usually removed and replaced during a solar installation. This is for two reasons: first, clay tiles are relatively fragile and may break when installers walk on your roof. Second, to properly secure your solar panels, your installer needs to bolt the feet of your solar racking equipment directly to your roof. With clay tile roofs, this area can only be adequately accessed by lifting tiles.

To properly anchor your solar panel racking, solar installers will typically remove clay tiles at the areas where they need to attach racking feet to your roof. Metal hooks and flashing are drilled into the roof, and your tiles can be slid back into place above the mounting feet. Depending on the exact shape and dimensions of the clay tiles on your specific roof, your installer may need to purchase or make uniquely-shaped hooks and flashing so they fit fasten properly under the tiles. Companies like SnapNrack make specialized mounting inserts for all types of tiles.

In some cases, installers might replace the original tile with a new metal version, essentially combining the tile, mounting foot, and flashing into one piece of equipment.

Can you install solar panels on slate and concrete tile roofs?

There's more work involved than with asphalt tiles, but solar panels work just fine on slate and concrete tile roofs. Clay, slate, and concrete tiles are usually removed and replaced during solar panel installation. In some cases, installers will drill through the tiles themselves, but it's more common to remove the tiles and replace them with a mounting foot and flashing because of the brittleness of slate and concrete.
