One of the most valuable parts of a full re-roof is the chance to inspect the timber structure underneath, something that simply is not possible while old tiles and felt remain in place. In Redcliffe, where properties range from converted historic buildings to newer apartment blocks, roof timbers can vary considerably in age, condition and even in how they were originally installed, so this inspection is never treated as a formality.
Once the old covering is stripped away, rafters, purlins and any noggins are examined for signs of rot, particularly near eaves, valleys and chimney junctions where water has historically found its way in. Timber is also checked for woodworm activity and for any distortion or sagging that might point to long-term overloading or moisture problems. On older Redcliffe buildings that have been converted or extended over the years, it is not unusual to find sections of timber that were patched or replaced at different times, and these areas get particular attention.
Where a timber is found to be significantly weakened, it is either sistered with a new length fixed alongside it or replaced outright, depending on how much of the structure is affected and how the roof is loaded. Minor surface issues that do not compromise strength are treated differently to genuine structural decay, and any findings are discussed with the homeowner before work proceeds, since timber repairs can affect both the programme and the overall cost of the job.
This stage is also when roofers confirm the timbers are suitable to take new battens and the chosen tile or slate, particularly if a heavier material is being specified than what was originally used on the property. Getting this right avoids problems appearing years later that would otherwise be hidden beneath a brand new covering.
The inspection is not only visual. Timber is often tested by probing with a bradawl or similar tool at suspect points, since rot can leave a surface looking sound while the wood underneath has lost most of its strength. On buildings around Redcliffe that have had extensions, loft conversions or previous re-roofing work carried out at different times, roofers also check that timber sizes and spans are consistent with current building practice, since older alterations were not always carried out to the same standard throughout the roof.
Where woodworm is found, the extent of the infestation is assessed rather than assumed to be historic and inactive, since ongoing activity can affect nearby timber even where individual rafters still look structurally sound. Any treatment needed is carried out before new battens go anywhere near the affected area.
A thorough timber inspection gives real confidence in what is being built on top, which is why Brunel Roofing Bristol always checks this before moving on to membrane and battens.
