wide is required to obtain an adequate overlap, which is best
installed before the first batten is fixed.
At the top the other roofing material may be lapped over the
top edge of the glass slates, again with lead flashing attached
to the batten above, to make the transition back to the other
material. Alternatively, if the solar slates go right to the ridge,
then finish with ridge tiles as detailed above.
At the sides, it is easiest if the strip runs out to hips, valleys
and/or verges, where it is finished as detailed above.
Alternatively, if the strip meets the incompatible material at
one or other side, a decision will need to be taken on-site as
to the best interface method, which will usually involve some
form of lead flashing.
When estimating materials using the website roof calculator,
treat this strip area as a whole roof.
