Garage roofs in Watford

Most garages in Watford have simple roofs, which is exactly why they are worth doing properly. A good fall, a sound deck and well-fixed edge trims are what stop a garage roof failing early. We check all three at survey and price any deck or gutter work up front, not as a surprise on the day.

When does a garage roof in Watford need replacing?

Water from a failing garage roof in Watford does not always stay in the garage. On an attached garage it can run down the house wall or track under the flashing, and a blocked or broken gutter can spill onto the drive or a neighbour's property. Replacing the roof deals with the source.

Around Watford, flat roofs are common on terraced streets with flat-roofed rear kitchens and bathrooms and on bungalows with flat-roofed side extensions and dormers. 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.

Do I need planning permission or building regulations for a garage roof?

Usually not for planning, and often not for building regulations either, if the garage is detached and unheated. Re-covering a roof without materially changing its appearance does not normally need a planning application.

An unheated detached garage is not normally a thermal element, so the insulation rules for renovated roofs do not usually apply. That changes if the garage is attached and heated, used as a room, or being converted. A new roof covering that adds 15% or more to the existing weight, or any structural change, still needs building control approval in England. Wales has its own threshold for re-roofing, Scotland works through building standards and NI through district council building control.

Listed buildings and conservation areas can bring extra controls. We confirm what applies at survey and handle approvals where they are needed; our building regulations page covers the detail.

What's included?

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.
