Local knowledge
What we see on Harlow roofs.
Roofs & housing in Harlow
Harlow was designated a New Town in 1947 and built to Frederick Gibberd's master plan, so the housing is unusually consistent: 1950s and 60s terraces and semis, many with shallow pitches and simple unbroken roof planes that take a full array without cutting around dormers. The later infill estates use modern trussed roofs, which are quick to mount. Some of the original blocks carry flat or near-flat roofs - those get tilt frames rather than in-plane rails, and we price the frames in from the start.
Planning & permissions
Almost every Harlow install proceeds under permitted development. The exception is Old Harlow, where the historic core is a conservation area and a street-facing array needs checking before anything is ordered. Flat-roof installs on the original New Town blocks have their own height rules, which we confirm at the free design stage.

Real pricing, custom design
Every Harlow design is built around your actual roof and usage — not a package price off a website. We design from aerial imagery before anyone visits, then confirm on site, across CM17–CM20 and neighbouring Old Harlow, Church Langley, Newhall. Your free design is usually back within 24 hours with the full price in writing.
Package prices are based on one roof elevation with a single scaffold lift. Extra roof faces or additional scaffolding are quoted at survey.
