Housing stock — AL7 and AL8 are dominated by 1920s-40s Neo-Georgian tile-and-render properties with distinctive matched roof lines — replacement tile must maintain the original run colour.
Local roofing challenge — The whole garden city core is a conservation area with restrictive covenants held by the Howard Trust — like-for-like tile colour, matching ridge and unchanged chimney pot profile are non-negotiable, and we handle Trust liaison at quote stage.
On the ground — AL7 Neo-Georgian terraces along Parkway share matched roof lines — a single mismatched tile is visually obvious across the row, so we source colour-matched stock and photograph reruns for Trust approval.
Microclimate — The garden city planning preserved mature tree canopy across every avenue — leaf load into valleys and hoppers is heavy and annual gutter clear is essential.
Site access — AL7 residential avenues have strict Welwyn Hatfield CPZ — we book contractor permits at quote stage.
