Flat roofing contractors in Surrey

Commercial owners and facilities managers in Surrey can use a paid condition report to plan budgets, then phase re-roofing over one or more years with each section priced separately. When you are ready to replace, the survey and fixed written quote are free, and building control is handled where the work needs approval. We install extensive green and sedum roofs across Surrey as part of new flat roofs on extensions, garages, garden rooms and small commercial buildings. A structural check comes first, then new root-resistant waterproofing, then the drainage, growing medium and sedum. You get a fixed written price after the free survey.

Which flat roofs are common in Surrey?

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. Across Surrey, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, 1960s and 1970s link-detached houses with flat-roofed garages and porches and bungalows with flat-roofed side extensions and dormers. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Surrey?

Flat roof repairs

Flat roofs in Surrey face the same enemies as anywhere else: rain driven against walls, leaves blocking outlets, sun drying out older felt and frost opening small cracks. People tend to notice when a stain appears on a ceiling after a storm, or when water is still sitting on the roof days after rain.

Torch-on felt roofing

For a commercial roof in Surrey, such as a shop, surgery or club, torch-on felt offers a hard-wearing mineral finish that takes occasional maintenance traffic. Phased work keeps part of the building weathertight while the rest is re-roofed, so the business can usually keep trading.

Flats, HMOs and block roofs

A block roof in Surrey is a long-term asset, so we talk about whole-life cost as well as the price today. A longer-life system with corrected falls can mean fewer reactive repairs and fewer rounds of consultation over the years, and the survey explains the options in plain terms.

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.
