New Roofs in Cardiff & Across Wales

Costs vary quite a bit depending on the size of your property, the pitch and complexity of the roof, and the materials you choose. As a rough guide, a new tiled roof on a standard three-bedroom semi-detached house in South Wales typically falls somewhere between £5,000 and £9,000 including scaffolding and waste removal. Slate roofs tend to sit higher — £8,000 to £13,000 for the same size property — because the material itself costs more and takes longer to lay. Flat roofing systems for extensions or garages are less expensive, usually in the £2,500 to £6,000 range depending on the area covered. We provide a detailed written quote after surveying your property, so you know exactly what is included before any work begins.

The honest answer is that it depends on the extent of the damage and the age of the existing roof. If you have got a couple of slipped tiles or a small patch of failed mortar, a repair is usually the sensible option. But when problems start multiplying — persistent leaks returning in different places, widespread cracking, sagging ridges, or daylight visible through the boards in the loft — that is typically a sign the roof has reached the end of its useful life. Repeated repairs on a roof that is past its best often end up costing more over time than a single replacement would. We always inspect the roof before making a recommendation and will tell you straight whether a repair or a new roof makes more financial sense.

For a typical terraced or semi-detached house in Cardiff, you are looking at roughly three to five working days for a full strip and re-tile, weather permitting. Detached properties with larger or more complex roofs — hipped roofs, multiple valleys, dormer windows — can take a week or longer. Flat roofing projects tend to be quicker, often two to three days. We will give you a realistic timescale in the quotation stage and keep you updated if weather or any unexpected findings affect the schedule.

In most cases, no. Replacing your roof with similar materials and a similar profile is normally classed as permitted development and does not require planning permission. However, there are exceptions. If you live in a conservation area, if your property is listed, or if you are planning to change the height or shape of the roof, you may need to apply. Building Regulations approval is a separate matter — all new roofs must comply with current standards for structural integrity, insulation, and ventilation. We handle the building regulations side as part of our service.

All new roof installations come with a written workmanship guarantee. The length depends on the scope of the project, but for a full roof replacement it is typically between 10 and 20 years. Many of the materials we use also carry separate manufacturer warranties — for example, most concrete and clay tiles are guaranteed for 30 years or more. We will explain exactly what is covered in your quotation so there are no grey areas.

Yes, and we would usually recommend it. Since the scaffolding is already in place, adding new guttering, fascias, and soffits during a roof replacement saves money on access costs and means everything is done in one visit. Old or damaged gutters can undermine a brand new roof by allowing water to back up under the tiles, so it makes practical sense to address both at once.
