When starting any type of home improvement or building work, most conscious property owners will want to know if the project will be affected by planning permission or building regulations. But what about when it comes to your roofing? Whether you’re looking for a new roof for commercial properties or a domestic dwelling, there are some key building regulations to be aware of. While there are rules covering everything from work to your existing roofing to rooflight installations and loft conversions, there are also specific ones for a brand new roof. These are the regulations which you’ll need to adhere to if building a new home extension, for example. Here are some of the key points to know.
A new roof will need to provide adequate weather resistance. This will largely come down to the covering and materials chosen. For pitched roofing, this will normally be slates or tiles, but for those building an extension, it’s usually going to be a high-quality flat roofing material. When examining the weather-resistant properties of a new roof, a good water drainage system must not be forgotten. A new roof should also be secured properly to stop it lifting in strong winds.
If a fire broke out in your home, all new roofs must show they could adequately resist its spread from one property to another. This means that if a fire were to start in either your property or a connecting neighbour’s home, the chances of the fire spreading across the roofing boundary would be decreased.
You should never treat the strength of your roof lightly, even when considering things like hanging Christmas decorations from it or climbing up onto your flat roof. That said, building regulations do require that new roofs support certain loads. These span across three categories. The roof needs to support all materials used (e.g. tiles, felt etc.), weather elements (e.g. rain and snow) and people. By ‘people’, the regulations mean the roof will need to support the weight of anyone accessing the roof to perform maintenance and repairs.
Most property owners understand the need to create an energy-efficient property which reduces heat loss. While building regulations for this are more commonly associated with new windows and doors, it’s also important that a new roof also has the right insulation.
To stop condensation forming within your property, some new roofs must prove they offer good ventilation benefits. Warm roof systems don’t usually require this thanks to the insulation installed on top of the rafters or joists. However, building regulations do require all other systems (i.e. cold roof systems) to be ventilated.
