Which flat roofs are common in Conwy?
Flat roofs in Conwy sit on shops with flat-roofed rear stores below flats, newer estates where the first extension roofs are now being replaced and lock-up garage blocks on estates. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof. Approximate 1991–2020 regional averages based on Met Office data.
Building regulations in Wales
Welsh guidance is that most re-roofing needs building control approval, so it's worth checking whenever more than a quarter of a roof is replaced or repaired. Renovated roofs are upgraded to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K under the Welsh Approved Document L. In Conwy the application goes to Conwy County Borough Council. More on the rules.
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.
How long does a garage roof replacement take?
A single garage roof is typically finished in one or two days, and a double garage in two or three, weather permitting. Deck repairs and new fascias add time.
Disruption is light. You will need to empty or cover anything stored in the garage, because dust and debris can fall through gaps in an old deck during the strip. The garage door may be out of use for part of the job, and the car is best parked elsewhere so a skip can sit on the drive. We keep the roof weathertight at the end of each day.

Do I need to empty my garage before the roof is replaced?
It helps to clear valuable or delicate items, and to cover the rest with dust sheets. Debris can fall through gaps in an old deck during strip-out.
Is it worth repairing a garage roof instead?
If the roof is generally sound and dry with one isolated defect, a repair is usually sensible. Widespread cracking, a soft deck or repeat leaks point to replacement.
Can you put a new roof on a garage with a cement sheet roof?
Yes, once any suspected asbestos has been tested and removed by a licensed specialist. The garage then usually needs new timbers and a deck before the new membrane goes on.
