Rafters do the heavy lifting on any pitched roof, carrying the weight of the battens, membrane and covering down to the walls of the house and ultimately into the foundations below. On the mid-twentieth-century semis and terraces common around Ridgeway, these timbers have often been in place, untouched and unseen, since the property was first built decades ago, quietly doing their job through countless winters. Discovering damage to them during a re-roof is not unusual, and it is worth knowing what happens next so that the prospect does not feel alarming if it comes up during your own project.
The first step is always assessment rather than assumption, because acting too quickly on a rafter that only looks bad can mean unnecessary work and expense, while ignoring one that looks fine but is not can mean a genuine problem gets missed entirely. A damaged rafter can look worse than it actually is, discoloured from old moisture but still structurally sound, or conversely can hide more serious decay beneath a sound-looking surface that gives little away. A roofer will check for softness underfoot, splitting along the grain, insect damage and any sign of previous water tracking down the length of the timber, then decide whether the affected section can be repaired locally or needs a longer length replaced entirely.
In many cases, the answer is sistering: fixing a new, structurally sound length of timber alongside the damaged rafter so it shares the load and restores full strength without needing to remove the original piece entirely, which can be disruptive, slower and more costly than necessary. Where damage is more extensive, particularly near the eaves or around a chimney where water has been getting in for some time undetected, a full rafter replacement may be the safer and more durable option, even though it takes a little longer and requires more careful handling to carry out properly. The choice between the two is rarely arbitrary, and a competent roofer will explain the reasoning behind whichever method is proposed for your particular roof.
This work is carried out before the new roof covering goes on, since there is no practical way to reach and repair rafters properly once battens and tiles are sitting in place above them. It does add time and, usually, some cost to a project, but skipping it in favour of a quicker job would leave a brand new roof sitting on a compromised frame, which is a false economy for any homeowner in Ridgeway who wants their new roof to genuinely last as long as it is meant to for years to come. Fixing a rafter properly at this stage is also far cheaper, in the long run, than dealing with the consequences of a hidden defect later, once tiles, battens and membrane are already in place above it.
