Slate roofing.
Natural and fibre-cement slate can provide a clean, durable finish for full re-roofs, extensions and traditional properties. Where suitable, existing Welsh slates can be reused as part of a re-roof. The correct slate size, headlap, fixing and detailing are set by the roof and its exposure.

Which slate options does JDL work with?
JDL works with natural and fibre-cement slate for traditional and modern properties. Existing Welsh slates can also be reused as part of a re-roof where suitable.
What affects the slate roof specification?
The roof pitch and exposure help determine slate size, headlap, fixings and detailing. JDL assesses those conditions before agreeing the slate and setting out the roof.
Can photographs help with the first assessment?
Yes. Ground-level or safely taken photographs can provide useful context. A final specification may still require an on-site roof survey.
