Roof Structures & Loft Conversions
The roof structure is the vital timber framework that supports your property’s weatherproofing. In recent years, loft conversions have become an incredibly popular way to add space to homes. However, altering a roof is a highly complex undertaking. When you book a house survey, verifying the integrity of the roof timbers and checking any modifications is a critical part of the process to ensure the building remains safe and stable.
Properties in the Gloucester area feature a wide variety of roof designs. Older period homes typically have traditional cut timber roofs, which offer open loft spaces but can suffer from sagging, historic movement, or timber decay over time. More modern homes usually rely on prefabricated truss roofs. While these are highly engineered and very strong, the intricate web of timbers cannot be safely cut or altered to create storage space without severely compromising the structural integrity of the entire roof.
Hidden Risks
This brings us to the hidden risks of unauthorised or poorly executed loft conversions. A conversion where vital supporting timbers, such as purlins or struts, have been removed to create headroom can quickly lead to roof spread. This is a serious defect where the weight of the roof pushes the external walls outwards. Furthermore, if the original ceiling joists were not upgraded to support the heavy load of a new floor and furniture, it can cause severe deflection and cracking in the ceilings of the rooms below. An RICS qualified surveyor knows exactly what warning signs to look for during a physical inspection.
Expert Assessment
When conducting RICS Level 2 Home Surveys, we safely inspect the accessible roof space to evaluate the condition of the timbers and check if any alterations appear to lack the proper building regulations approval. If a building surveyor suspects that structural supports have been removed unsafely to create a makeshift room, we will strongly advise obtaining a Structural Engineer Report to detail the exact reinforcements required to stop the roof from failing.
It is also important to remember that an illegal or structurally unsound loft conversion cannot legally be marketed as a habitable bedroom. If significant restorative work is required to make the space safe, or if it lacks the necessary certifications, obtaining an RICS valuation will ensure you understand the true market value of the home and are not overpaying for floor space that does not technically comply with building standards.
