When does a garage roof in Ealing need replacing?
Many garages in Ealing still carry their original mineral felt, which may have been patched several times. Once the chippings have washed off and the laps have split, water gets under the felt and into the deck, and patches stop holding. At that stage a full replacement is the practical fix.
Ealing's flat roofs are mostly on shops with flat-roofed stores below flats above, with plenty on Victorian and Edwardian terraces with flat-roofed back additions too. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.

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.

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.

How much does a new garage roof cost in Ealing?
£1,900–£3,350 for a typical 18 m² garage roof in EPDM, at London guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Should I insulate my garage roof?
Only if the garage is heated or you plan to use it as a room. Insulating a cold, unheated garage roof can cause condensation unless it is designed carefully, so we advise case by case.
Can you replace a shared garage roof in a block?
Yes. We can quote for one garage in a row or the whole block, and we take care with the joins between bays so neighbouring roofs stay watertight.
