Frequently Asked Questions
How are PV roof hooks mounted?
Directly on the rafter beneath the roof tile. The tile is replaced by a flashing tile.
Do I absolutely need flashing tiles?
Recommended – they prevent tile breakage and ensure watertightness.
What screws do I need?
Special PV roof hook screws made of stainless steel (e.g., ASSYplus A2).
When do I need a stiffening rail?
For larger spans or higher loads due to wind or snow.
Are the components weather-resistant?
Yes – all components are designed for long-term outdoor use.

Show your roof — help the next builder
Photos say more than any data sheet: upload pictures of your installation and write briefly how it went. Others can then see how the tile actually sits on their profile — and pick the right one faster.
- Which tile profile is on your roof
- How the fit and installation worked out
- A photo of the finished spot — please without house numbers or licence plates
How we handle reviews
Reviews are collected and stored via Judge.me. Reviews that we can match to a confirmed order are marked as a verified purchase. We publish reviews unchanged and do not shorten them in substance. We do not pay for reviews and we do not delete negative ones. We only remove contributions that break our rules — insults, advertising, or personal data of third parties.
