Most houses are designed with a pitched roof, as this is the most reliable and effective method to weatherproof a building. Historically pitched roofs were constructed on site from loose sawn timber. Nowadays, the more common form of roof structure is a pre-fabricated frame called a “trussed rafter”. These are predesigned and manufactured to meet the loading requirements of the building, taking into account span, roof pitch and weight of the roof tiles or slates.
Unlike traditional roofs, where the purlins take much of the load, trussed rafter roofs are not usually suitable for conversion because to remove or change any component would weaken the structure.
One of the big benefits of pitched roofs has emerged in recent years as more and more homeowners have taken the opportunity to increase the number of bedrooms in the property by converting attic space into living space.
