Local Coverage
Stevenage divides between Old Town heritage and new-town housing
Stevenage's housing splits cleanly. Stevenage Old Town along the High Street carries genuine period stock — Tudor and Georgian timber-framed and brick properties, Victorian terraces, listed building and conservation-area work. The post-war 'new town' running south of the Old Town is dominated by 1950s–1970s housing, with later infill and modern executive development around Knebworth, Aston and the western edges.
Both halves are regular work for us. Lime mortar and sympathetic detailing on Old Town conservation work; conventional re-roof, roofline and refurbishment scope on the new-town stock. Travel time from our Ugley base is typically 50–60 minutes via the A120/A1(M).
Standard cover applies — same-day for active leaks, 5 working days for survey bookings, out-of-hours response on 07379 964569.

Volume re-roofing on new-town stock
Most Stevenage new-town concrete-tile roofs were laid 1955–1975 and are at end-of-life. Full strip-and-re-roof to modern standards with new underfelt, battens and dry ridge.
Old Town conservation experience
Lime mortar, period detailing and listed building consent applications are standard for our Stevenage Old Town work — not specialist add-ons we charge a premium for.
Local Issues
Common roofing & building issues in Stevenage
Across the Stevenage new town the dominant call-out is end-of-life concrete tile roofs on the post-war housing — Marley and Redland concrete tiles laid 1955–1975 are now at the end of their 50–60 year service life. Symptoms: widespread tile slippage from nail fatigue, sagging ridges, soft underfelt and rising winter leaks.
Full UPVC roofline replacement is the second-most-common scope on the same stock — original painted timber fascias have rotted out and once water tracks behind the painted face, the timber goes quickly. Strip-and-replace eliminates the maintenance cycle.
Stevenage Old Town brings a different set of problems: chimney repointing in lime mortar on Tudor and Georgian stacks, slate and clay-tile roof repair, oak frame repair on the older medieval buildings, and damp diagnosis on listed properties (typically misdiagnosed bridged DPCs rather than rising damp). Sympathetic materials and conservation-officer coordination throughout.
