Metal roofs have different types of roofing systems, including standing seam roofs, trapezoidal roofs and corrugated roofs, etc. For standing seam roofs, it is relatively simple to install solar panels, and the solar roof clamps can be directly clamped on the seams. Whereas, corrugated and trapezoidal roofs usually require a direct connection to the roof structure. Waterproofing is especially important as the flashing cannot slide under it.

Installing Solar Power on Standing Seam Metal Roofs

If your roof is a metal standing seam roof, you can use a solar panel mounting system roof clip on the seams. This way, there is no need to drill holes in the roof. Your solar installation will be faster, less labor-intensive, and you won't have to worry about roof penetrations and leaks.

Standing Seam Roof Clamps

The standing seam roof clamp is made of high-strength aluminum alloy and uses two bolts to hold the clamp.

Installing solar energy on a trapezoidal metal roof
Trapezoidal roofs generally have flatter areas between each peak, and the height of each ridge may vary. Therefore, the shape of the brackets for trapezoidal metal roofs may also vary.
The installation method is to have each bracket fit snugly on each trapezoidal ridge to ensure optimal drilling is placed above the foundation level of the roof.

Roof Clamp Bracket bases are fitted with rubber gasket seals.
In any case, standard practice for this type of roof is to use a sealant to ensure there are no leaks.
Installing solar energy on corrugated metal roofs
A corrugated roof is a roof clamp installed between two crests, and like a trapezoidal roof clamp, the base of the clamp is fitted with a rubber gasket seal.

If your metal roof is corrugated or trapezoidal, then you also need to pay attention to protection against falls and roof leaks. Because there are no fixed seams to clamp the roof anchors, the safety device must be attached directly to your roof.
This means drilling a hole in the roof structure to hold this anchor. Make sure that the fall arrest anchors your installers use won't leak water from your roof when the anchors are removed after the job is done!
