Can solar roof attachments cause water intrusion?

Installing solar roof attachments requires drilling dozens of holes through roofing material, making any roof vulnerable to water intrusion. Given this reality, it’s important to understand how water intrusion (and the resulting building damage) occurs and ways installers can prevent it from happening.

How much does it cost to waterproof a rooftop solar system?

Improperly waterproofing a rooftop solar system is expensive. The labor costs to repair smaller leaks often range between $500 and $1,000. If the problem is bigger, flashed mounts or the whole roof may need replaced.

Can solar PV be installed on a flat roof?

To install solar PV on south facing flat roof we would use a ballasted system. This means the roof is not penetrated (which would let in water on a flat roof), and the system is unable to be lifted or tipped over by the wind. The triangular mounting frames are preassembled and placed on aluminium feet.

Can solar panels be mounted on a roof?

Solar panels are predominately mounted on a supporting framework. The interface between the support framework and the roof covering is critical and if not taken care of correctly can cause damage to the roof membrane and potentially the structure as well. There are three main ways to mount the solar framework to the roof; 1.

Can a roof waterproofing system be installed without a membrane?

The system can be placed without penetration of the roof waterproofing membrane. Integrated cable channels, stackable components and the requirement for only a few tools, considerably reduces the working time on the roof.

How do I protect my solar panels from leaking water?

It is recommended to use high-quality flashing materials, such as metal or rubberized membranes, and to correctly fasten and seal the flashing to the roof surface. Waterproofing Solar Panel Mounts: To stop water from leaking beneath the solar panels and harming the roof, the solar panel mounting points must be sealed.
