Repair or Replace: Getting the Decision Right

The choice between repairing a roof and replacing it entirely is one of the most important - and most mishandled - decisions in domestic roofing. Repair too little and you spend money repeatedly without resolving the underlying cause. Replace when a repair would have done the job and you spend far more than necessary. Getting this right starts with understanding what the roof is actually telling you.

What a New Roof Involves

A full roof replacement means stripping the existing covering back to the rafters, inspecting the timber structure, replacing damaged or rotten wood, fitting a new breathable underlay membrane, and relaying tiles or slates from ridge to eaves. Flashings around chimney stacks, abutments, and valleys are replaced at the same time, and ridge and hip details are finished to current standards - typically with mechanically fixed dry-ridge systems rather than mortar bedding.

On a standard three or four-bedroom detached house in the Taverham area, a full replacement typically costs between £7,000 and £12,000 depending on the roof size, pitch, material specification, and how much timber work is needed once the old covering is stripped. That figure should include scaffold, full strip and disposal, membrane, battens, tiles or slates, and all lead work.

When a Repair Is the Right Answer

Not every roofing problem needs a full replacement. A repair is the sensible choice when the issue is clearly isolated and the rest of the roof is structurally sound. Signs that a targeted repair will hold include:

• A small number of slipped, cracked, or missing tiles in one area, with no widespread pattern of failure
• Flashing failure at a chimney or parapet wall where the underlying tiles are undamaged and in good condition
• A single valley that has corroded or cracked, with no evidence of damage spreading to the main slopes
• Storm damage to a section of ridge or hip tiles where the rest of the ridge line is intact

A roof that is 10-15 years old and otherwise in good condition can often be repaired economically. The tiles will likely have many years of useful life left in them, and spending a few hundred pounds on targeted work makes sound financial sense.

When Replacement Makes More Sense

There are situations where repeated repairs become false economy. A common pattern is a roof that leaks in one place, gets repaired, then leaks somewhere else six months later. This typically means the covering has reached the end of its useful life across most of its area, and each repair is simply finding the next weak point rather than addressing the underlying condition.

Replacement is usually the better option when:

• The tiles or slates are visibly deteriorating across most of the roof - widespread moss and lichen can accelerate this, but the problem is usually age and material degradation
• The mortar-bedded ridge is failing along its whole length, cracking and dropping sections - at this point a full re-ridge at minimum, or a full strip, is more economic than repeated pointing
• The underlay (the felt beneath the tiles) has deteriorated and is allowing water to enter even where tiles are intact - this is common on roofs over 40 years old where the original felt has become brittle
• There is evidence of widespread timber decay in the rafters or purlins, which often only becomes apparent when the covering is lifted
• The roof has had multiple patch repairs over the years and no single repair area can be defined cleanly - the whole surface is a patchwork

The Age of the Roof as a Guide

Concrete interlocking tiles, which cover the majority of post-war housing, have a realistic working life of around 40-60 years. Natural slate, properly fixed, can last considerably longer. Plain clay tiles are similarly long-lived if the original fixings have not corroded. If your roof is approaching or past these thresholds, even a small leak can be a reasonable prompt to assess the whole surface rather than just patching the immediate problem.

An honest roofer will tell you clearly where on that spectrum your roof sits, and whether a repair buys you five more years or five more months. If you are getting vague answers, ask directly:
