What flat roof work do we do in Thatcham?

Single-ply membrane roofing

For a commercial roof in Thatcham with rooflights, plant and outlets, single-ply's welded details give a consistent finish. Pre-formed corners, membrane-coated trims and welded kerbs are all made in the same material as the main roof, which keeps the roof consistent and simplifies any future repairs.

Torch-on felt roofing

Torch-on felt is widely specified for blocks of flats and HMOs, in Thatcham as elsewhere, because the system is well understood, widely repairable and governed by a British Standard code of practice. Three-layer builds with insulation are common on larger, multi-occupied roofs.

GRP fibreglass roofing

GRP is a good fit in Thatcham for roofs with awkward shapes, short runs of upstand and lots of corners, because every detail is laminated in place rather than cut and glued. Where a sheet membrane would need many joins, fibreglass forms one continuous skin across the whole roof.

What flat roofs are typical in and around Thatcham?

In a town like Thatcham flat roofs are mostly on low-rise post-war blocks of flats and terraced streets with flat-roofed rear kitchens and bathrooms. Local weather shapes the specification. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain. Approximate 1991–2020 regional averages based on Met Office data.

Where approval is needed it goes to West Berkshire Council building control, or a registered building control approver.
