How does the installation of solar panels affect the durability of the roof?

The installation of solar panels can affect the durability of the roof in many ways. First, solar panels add weight to the roof, which can cause extra stress on the structures. This can lead to roof damage or even collapse if the roof is not strong enough to support the additional weight.

Second, installing solar panels requires holes in the roof to attach the panels. These holes can weaken the waterproofness of the roof and expose it to moisture. This can lead to leaks and mold growth under the roof, which can damage roof structures and insulation.

However, it is important to note that professionally installed solar panels do not necessarily damage the roof if the roof is strong enough and the installation is done carefully. In addition, there are different installation methods, such as inclined or integrated installation, which can reduce the load on the roof and minimize possible damage.
