The roof structure comprises traditional cut timbers, which have been cut on site by a carpenter rather than being pre-fabricated and craned into position, as is common with many modern roof structures. The structure includes a ridge beam at the apex of the roof, multiple rafters forming the diagonal timbers beneath the tiling, purlins which are horizontal timbers approximately at the midpoint of the rafters, and purlin struts supporting the purlins. Beneath these are the ceiling joists, which are smaller than those found between the ground and first floors and are generally designed only to support the weight of the ceiling and a limited additional load above. A bituminous felt membrane is present below the tiles but above the roof structure. This type of membrane is no longer widely used, as it is highly resistant to the passage of moisture. Consequently, as warm, moist air enters the loft space, it can condense on the underside of the felt during colder months. Over time, this condensation may track into the timber, potentially leading to decay. It is therefore recommended that ventilation is improved. This could include installing vents in the front and rear roof pitches and selectively cutting small pockets of felt to improve airflow and reduce the risk of condensation. It was observed that new timbers, including collars and diagonal braces, have been installed within the roof structure. This is likely to provide additional support, as the original timbers may not have been sufficient to carry the weight of the newer Redland interlocking 49 concrete tiles. These new timbers appear to have been installed to prevent movement and provide reinforcement. In my opinion, the diagonal braces are providing little, if any, support to the roof structure. Ideally, additional strut timbers should have been installed to provide adequate support to the structure. Additionally, one of the rafter timbers in the centre of the front pitch has twisted significantly, likely due to movement caused by the weight of the newer roof tiles. Other rafters have also twisted and 3 Inside the property Limitations on the inspection E1 Roof structure 1 2 3 NI RICS Home Survey – Level 3 Page 40
distorted, although to a lesser degree than the timber mentioned above. It is suspected that the movement in the roof timbers has now settled. Although the movement is believed to have settled, it is advised that a qualified roofing contractor inspects the roof structure. The contractor should provide a quotation to repair or replace the twisted rafter timber to ensure the roof is adequately supported. It is also recommended that they provide a quotation to install additional strut timbers to offer further support and prevent future deflection. Quotations should be obtained before committing to purchase the property. Signs of rotting timbers were observed beneath the valley gutter, which is suspected to be due to a leak from the roof in this location. However, the roof in this area could not be fully inspected, as it was significantly obstructed by vegetation. It is recommended that a qualified roofing contractor inspects the roof to confirm whether an active leak is present and to provide a quotation for any necessary repairs. Additionally, it is advised that the timbers in the loft space are inspected by a timber and damp specialist to assess their condition. This inspection should determine whether the timbers require replacement or if repair is possible. A thorough check for woodworm should also be conducted, as there may be an infestation that was not visible during this inspection. It should be noted that the vendor had stored a significant number of items in the loft, which restricted access and limited the inspection. Air vents have been installed on both the front and rear roof pitches in the loft space to provide ventilation and reduce the risk of condensation. However, when testing the timbers for moisture content, readings of approximately 22% were recorded. This is indicative of condensation, likely exacerbated by the presence of the bituminous felt membrane. It is recommended that additional ventilation be provided, for example, by installing two further air vents on the rear pitch to improve airflow. It should be noted that timber is generally considered at risk of decay or timber defects, such as rotting or woodworm, when the moisture content reaches 25–30%. Although no visual signs of timber defects were observed during the inspection, the current readings of 22% indicate that the timbers are approaching a level where deterioration could occur if conditions persist. Areas of the structure that were not visible may also be affected. Elevated moisture readings were also recorded in the party walls within the loft space. This is likely due to loose coping stones and damaged render on the external party walls, allowing rainwater ingress. Repairs to these external elements are now required to prevent further water penetration and potential timber or structural defects. It should also be noted that a wasp’s nest was observed within the loft space; this appeared to be inactive at the time of inspection. It should be noted that whilst there is a small amount of insulation present within the loft, this is not enough to comply with minimum recommendations. It is currently suggested that a minimum depth of 270 mm using glass fibre or mineral fibre insulation is provided for, and you should install this now, taking care not to reduce ventilation. Care should be taken when climbing into and out of the loft, so as not to fall. When moving around within a loft, you should only tread upon clearly carefully secured boarding underfoot, and where there is no boarding, you must not tread between the timber structure underfoot. Doing so will apply load upon the ceilings, which are not designed for this, and you would fall through. Insulation often covers the timber structure and extreme care must be taken.

following a survey done on a property we’re about to purchase which highlighted the main roof coverings as something that required urgent attention.we are looking for a quote to determine the cost of repair. it appears some of the roof tiles are dislodged as light was visible from the roof space. the dislodged tiles would need to be reattached. the survey states the tiles should be fixed correctly to avoid water retention. please email me for photographs.
