What flat roof work do we do in Harlow?

Single-ply membrane roofing

On exposed sites in Harlow and elsewhere, mechanically fixed single-ply is specified with a fixing pattern based on wind uplift, with extra fasteners at corners and edges. That makes it a strong option for commercial roofs where wind loads are a concern.

Dormer roofs

High, exposed dormers in Harlow take the full force of the wind and rain. Edge trims loosen, flashings lift and the felt at the drip edge cracks. Once the faults spread around the perimeter, a new roof with fresh trims usually lasts far longer than another round of repairs.

Commercial flat roofing

We are flat roof specialists, so a commercial roof in Harlow gets a system chosen for the job: single-ply for large, simple areas, built-up felt where there is foot traffic and plant, or a liquid overlay where the existing roof is sound. The survey explains the trade-offs in plain terms.

What flat roofs are typical in and around Harlow?

In a large town like Harlow flat roofs are mostly on shops with flat-roofed rear stores below flats and lock-up garage blocks on estates. Local weather shapes the specification. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof. Approximate 1991–2020 regional averages based on Met Office data.

Who approves flat roof work in Harlow?

Where approval is needed it goes to Harlow Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
