Insulated roof panelss on a T-shape conservatory

Panels are a common budget route for large T-shapes, because a full tiled roof on this size can be a five figure job.

  • Two valleys, several hips and long gutter runs make labour the biggest part of the price.
  • Large glazed floor areas get very hot under polycarbonate or glass, so these rooms benefit most from a solid roof.
  • Bigger roofs are more likely to need structural calculations and extra posts.
