Thetford Roofers helps homeowners in Bury St Edmunds choose the right exterior cladding material for their property, with an honest assessment of what each option actually delivers.
There is no single best cladding material. The right choice depends on your budget, the age and construction of your property, how much maintenance you want to do over the years, and the look you are after. We install cladding on homes across Bury St Edmunds and the surrounding area, and we will always give you a straight answer about what suits your situation - not just what is easiest to sell.
Below is an honest breakdown of the main materials available, including the downsides that do not always get mentioned.
uPVC is the most widely fitted cladding material on UK homes and for straightforward reasons: it is low-maintenance, resistant to moisture and relatively affordable. It does not need painting, it will not rot, and it is easy to clean with a hose and a soft brush.
The drawbacks are real, though. uPVC can look plastic if you are trying to match an older property, and the colour range - while wider than it used to be - is still limited compared to timber. It can also become brittle with age and UV exposure, and once it cracks, the panel needs replacing rather than repairing. In very hot weather, lighter-coloured panels can expand noticeably; poorer installations without adequate expansion gaps can buckle.
Timber is the traditional choice and, done properly, it looks excellent on the right property. It is a natural material that can be painted or stained in any colour, it is easy to repair at panel level, and it is widely accepted on older or character properties.
The honest catch is maintenance. Painted timber needs repainting every few years - skip a cycle and water gets into the grain, the board begins to check and split, and you end up replacing boards rather than just refreshing the paint. Hardwood species hold their finish longer than softwood but cost more to buy and are heavier to handle. Treated softwood is cheaper upfront but needs more regular attention.
Feather-edge boarding, shiplap and rebated boards all have slightly different profiles and installation methods. The choice of profile affects how water is shed and how joints weather over time.
Fibre cement boards are made from a mix of cement, cellulose fibre and sand, pressed into boards or panels. They are dimensionally stable - they do not expand and contract as much as timber - and they resist moisture, frost and fire better than either uPVC or timber. Many boards come with a factory-applied paint finish.
The main limitation is weight. Fibre cement is significantly heavier than uPVC or timber, which means the wall and the fixing system need to be up to the job. Over-driven fixings crack the board at installation; under-driven fixings allow movement. It is a material that rewards careful, experienced fitting. It cannot be nailed like timber - specific fixing methods apply to each board profile and manufacturer.
Aluminium and steel cladding panels are more common on commercial properties and extensions than on traditional homes, but they are increasingly used on contemporary residential builds and on flat-roofed extensions. They are extremely durable, lightweight for their strength, and available in a wide range of colours and profiles.
The cost is higher than uPVC or timber, and the industrial look does not suit every property. Scratches and dents are harder to conceal on metal than on painted timber, and thermal movement needs to be designed into the fixing detail. On residential properties, the choice is usually limited to specific contexts - a garage, an extension, or a property with a contemporary design brief.
Cladding products sold in the UK carry CE marking or UKCA marking, which confirms that the product has been tested against declared performance standards - covering things like reaction to fire, water tightness and mechanical resistance. CE marking tells you that the manufacturer has declared a performance level; it does not, on its own, tell you that the product is correctly installed. A CE-marked panel fitted badly will still fail.
When comparing quotes, ask specifically what product is being used, not just what material. There is a significant difference in quality between budget-grade uPVC boards and well-engineered systems with proper fixing details and joint arrangements.
Whichever material you choose, the installation details that matter most are similar across all systems. Battens need to be treated timber or metal framing fixed securely to the wall. A breather membrane behind the cladding is essential on most installations to allow any moisture that gets past the outer layer to drain away without soaking the wall. Fixings must be the correct type and size for the board and the batten, and must resist corrosion. Joints, window reveals and base details must be correctly lapped or sealed.
The base of the cladding needs careful detailing - how it terminates above ground level affects whether water can track back behind the bottom course. This is where poor-quality installs often fail first.
If you are trying to decide which cladding material is right for your property in Bury St Edmunds, call Thetford Roofers and ask for a site visit. We will look at the wall construction, the current condition of your external finish, what you want the end result to achieve, and give you a straight comparison of the options that actually suit your building - not a sales pitch for the most expensive product.
