Maintenance
Generally, very little maintenance is required.
Roof maintenance
•
Cleaning
– these roofs do not need routine cleaning. There has been no history of
moss or lichen build up on these roofs, due to the natural weathering, and the
temperatures the glazing reaches in the sun.
•
Breakages
– glass roof slates are very robust, being stronger than natural slates.
They are edge sensitive however, and a lucky strike by a large stone or similar hard
object could break one. When broken they disintegrate into small fragments like
automobile glass
•
Removal & replacement, Solar Slates
– if broken, clean out the remaining fragments,
and bend the slate clip down. If intact, bend the clip down and ease the slate out
downwards. Push in a new slate, watching that it does not catch on the adjacent
screws. Silicone oil lubricant may be used to ease installation. Bend the clip back with
care to hold it in place.
•
Removal & replacement, Nu-lok Slates
– if broken, clean out the remaining
fragments. If intact, push the slate up by about 5mm, push the wire clips to the sides
and drop the slate out. To replace, move the stainless wire clips to the sides and push
up a new slate. Silicone oil lubricant may be used to ease installation.
