Garage roofs across Newport

Garage roofs across Newport range from original felt to old cement sheeting and earlier replacements that have not lasted. We assess the deck and fall first, then recommend EPDM, GRP, torch-on felt or a liquid system based on the garage itself. Any suspected asbestos is tested and dealt with by a licensed specialist before we start.

Which flat roofs are common in Newport?

Flat roofs in Newport sit on low-rise post-war blocks of flats, 1930s semis with flat-roofed garages and kitchen extensions and newer estates where the first extension roofs are now being replaced. 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 Newport the application goes to Newport City 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.

How much does a new garage roof cost in Newport?

£1,450–£2,600 for a typical 18 m² garage roof in EPDM, at Wales guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Which council handles building control for a flat roof in Newport?

It depends on where the roof is: in Newport that's Newport City Council. 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. We confirm which applies at the survey.

Can a garage roof be replaced in one day?

A small single garage with a sound deck can often be stripped and re-covered in a day. Deck repairs, a double garage or poor weather can stretch it to two or three.

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 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.
