What flat roof work do we do in Hatfield?

Liquid-applied roofing

Choose liquid roofing in Hatfield when the shape of the roof makes sheet materials awkward: curved edges, small dormers with many corners, or a mix of levels joined by short upstands. Each detail is reinforced in the same material as the main area, so the whole roof is continuous.

Flat roof replacement

A flat roof in Hatfield is often worth replacing because it is the weak point of the building: heat escapes through an uninsulated deck, rooms below are cold in winter and hot in summer, and condensation marks the ceiling. A warm-roof replacement deals with comfort as well as leaks, so it is worth considering before the roof fails outright.

EPDM rubber roofing

EPDM makes sense for a property in Hatfield when the roof is a straightforward shape, such as a garage or rear extension, and nobody needs to walk on it. A single sheet leaves few joins to fail, and because it is cold-applied there is no naked flame near timber fascias or a lived-in home.

What flat roofs are typical in and around Hatfield?

In a town like Hatfield flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and shops with flat-roofed rear stores below flats. Weather matters on a flat roof. 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 Hatfield?

Where approval is needed it goes to Welwyn Hatfield Borough 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.
