|We use 2 types of mounting systems; Schucho and Schlettter. They are both quality products and work in a simlar way, the reason we use two systems is that they are suited better to different panels.|
On roof mounting systems are installed by our dedicated roofing teams. A number of tiles are removed from the roof and the roof anchors are screwed directly into the roof truss giving a solid and secure platform to attach the mounting rails.
The mounting rails can run horizontally or vertiically depending on the orientation of the panels and the size of tiles on the roof. Either way the rails are fixed to the roof anchors using one turn screws. The panels are then fitted onto the mounting rails and secured in place.
Concrete Roof Tiles
Concrete roof tiles are relatively straightforward to work with. Initially the tile must be removed to allow the roof anchor to be screwed directly into the roof trusses. The tile is then replaced and it is checked to make sure it is not 'sitting up' too much. If it is sitting up above the other roof tiles a groove needs to be cut to allow the tile and roof anchor to sit flush with the other tiles. This is where our skillled roofers show their experience and make a very tricky job look easy.
Once all the roof anchors are secured in place the mounting rails are attached using the Schuecho connectors. The panels are then mounted onto the rails and secured using the Schuecho clips.
Slate Roof Tiles
We pride ourselves on being slate roof specialists. Considered one of the most difficult and delicate types of roof tile to work with, it requires skill and precision to make sure the roof is not damaged and the anchors are secured correctly.
Having installed solar panels on slate roofs all over the North West and North Wales we have encountered lots of different types of slate roof. Each has its own challenges but we have always managed to complete the job to the usual high standards we expect.
Securing Roof Achors To Slate Roofs
Traditional methods of securing roof anchors to slate roofs involve drilling and screwing directly through the slate. This method was designed for ease so anyone could do it i.e. electricians turned PV installers. The problem with this is that the screw which goes through the slate will need to move a little during high wind or will expand with high temperature and leaves the slate very brittle and liable to crack. Bearing in mind a solar system is designed to be on a slate roof for at least 25 years the last thing you want as a home owner is a cracked and leaking slate!
The Greener Group's Slate Roof Technique
We have developed a method for installing solar panels on slate roofs which allows the anchor a little bit of movement but is still watertight. By cutting a piece of the slate away to leave room for the anchor and flashing with lead it provides a secure and waterproof solution which allows movement and will avoid the tile cracking. The Greener Group has installed solar systems on lots of houses with many different types of roof and has gained a wealth of experience. If you would like more information or would like to see firsthand one of our slate or other type of roof installations please feel free to contact us.
