How safe and secure are they on my roof, especially during bad weather?
By design, we ensure they are safe.
Because of the highly windy unpredictable coastal area of Guernsey, we are careful to design the system to stay attached to your roof in all bad weather conditions. And for as long or longer than the design-life of the roof.
There are different types of roofing systems, some that sit within the roof taking the place of the slates or tiles and others that fit over the roof. Both are weathertight and guaranteed to be so. We advise you to inform your insurance company however, in case of something out of the ordinary occurring.
