All Over London Roofing provides flat roof installation across Tadworth and the KT20 area. Flat roofs are common on extensions, garages, dormers and some older properties, and modern materials have made them far more reliable than the flat roofs of decades past. Our fully insured team fits durable membrane systems designed to cope with UK weather, and we offer a free quote before any work begins.
More Information
Older felt flat roofs had a reputation for failing after a few years, but modern single ply and reinforced membrane systems last far longer when fitted correctly. We use quality materials suited to flat roofs of all sizes, from a small garage roof to a large extension. Getting the right system for your specific roof makes a real difference to how long it lasts.
A flat roof is never perfectly flat. It needs a slight fall built in so water drains away properly rather than pooling on the surface. Standing water is one of the main causes of flat roof failure, so we make sure falls, outlets and drainage are correctly designed and installed as part of every flat roof project we carry out.
Flat roofs on extensions and new builds need to meet current building regulations for insulation, and getting this right also helps keep the room below comfortable all year. We build insulation into the roof buildup correctly from the start, rather than treating it as an afterthought, so your finished space performs as well as it looks.
We recently fitted a new flat roof on a kitchen extension near Nork Park in Banstead, replacing an old felt roof that had been patched repeatedly over the years. The new membrane system, with properly designed falls towards a new outlet, has already coped well through a wet spell without a single sign of pooling. It is a good example of how the right materials solve problems that patch repairs never could.

We are proud to be based in this part of Surrey and to work in the community we live in. We have replaced roofs on the edge of Tadworth and Walton Downs, repaired gutters on quiet lanes in Burgh Heath, and fitted new fascias for families in Chipstead. When you call All Over London Roofing, you speak to someone who knows the roads and the roofs of the area you live in, not a national call centre reading from a script.

STILL NOT SURE?
A well installed modern flat roof in the Tadworth area can last twenty years or more, depending on the system used and how well it is maintained. Older felt roofs tend to need attention sooner. We can advise on the best system for your property during a free quote visit.
Single ply and reinforced membrane systems are generally the most durable options for extensions and garages in the Tadworth area. The right choice depends on your budget and the specific roof. We will talk through the options honestly when we visit.
Yes. Standing water usually points to a fall or drainage problem rather than the roof covering itself. We can inspect your flat roof and recommend the right fix, whether that is a repair or a full flat roof installation. Call All Over London Roofing on 01737448013.
