What flat roof work do we do in Slough?

GRP fibreglass roofing

GRP is a good choice in Slough when the roof will be seen or used: a dormer visible from the street, an extension overlooked by upstairs windows, or a roof that needs access for cleaning or maintenance. The hard, jointless finish and moulded trims give a neat result that copes with occasional foot traffic.

Flat roof surveys and leak tracing

Older extensions and garages in Slough frequently have felt roofs that have been patched several times. Before paying for another repair, many owners want to know whether the roof has much life left. That is exactly the question a condition survey answers.

Extension and kitchen roofs

Ponding against the house wall is a common reason for replacing an extension roof in Slough. When the deck dips near the wall or the fall runs the wrong way, water sits against the abutment and eventually gets in. A new roof with corrected falls moves the water to the gutter.

What flat roofs are typical in and around Slough?

In a city like Slough flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and terraced streets with flat-roofed rear kitchens and bathrooms. Rain and wind decide how a flat roof is detailed. 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.

Who approves flat roof work in Slough?

Where approval is needed it goes to Slough 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.
