Solar Waterproofing: How We Prevent Roof Leaks

With all of the different types of roofs out there, the first step to waterproofing a solar panel installation is as easy as following all manufacturer instructions and guidelines. But no matter what the roof, two things stay consistent—metal flashings beneath the shingles with silicone acting as an insurance factor.

But at Buffalo Solar Solutions, that’s not enough for the peace of mind of our customers. Our established installation method exceeds manufacturers’ expectations for sealing off the roof puncture. Here’s how we do it.

  • First, a pilot hole is drilled to prevent the rafters from splitting while installing the leg bolt. A thick seal of silicone is applied 360 degrees around the roof’s puncture point.
  • Next, a flashing with a pre-drilled lifted hole for the leg bolt is slid under three shingle layers, with an additional application of silicone added into the flashing’s lifted screw hole.
  • Finally, a six-inch leg bolt with an L-bracket is then threaded through the flashing into the pilot hole. As the leg bolt is tightened into the rafter, the silicone around the puncture hole further bonds the threads of the leg bolt to the rafter.

Paying close attention to detail during all parts of an installation helps us ensure that a roof-mounted solar installation stays free of leaks for the life of the system.
