What do commercial & industrial rooflights in Porthmadog involve?
Commercial & industrial rooflights in Porthmadog means rooflights for warehouses, schools, offices and retail units. We cover the LL49 district and the rest of Gwynedd, with a survey before any price is fixed.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Typical uses for commercial & industrial rooflights include industrial roofs with tired or fragile rooflight sheets.
Jobs in Porthmadog are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

- Continuous barrel-vault rooflights
- GRP or polycarbonate in-plane rooflight sheets
