Repair or Replace? How to Know When You Need a New Roof

One of the most common questions we're asked is whether a roof can be repaired or whether it's time for a full re-roof. The honest answer depends on the age of the roof, the extent of the problem, and how many times it's been patched before.

A repair usually makes sense when the damage is localised — a handful of slipped tiles, a single leak, or flashing that needs renewing. If the underlying felt and battens are sound, targeted repairs can add years of life for a modest cost.

A re-roof becomes the better investment when problems keep recurring, when the underlay has perished, or when more than around a fifth of the tiles are damaged. Older roofs with no breathable membrane, widespread moss damage, or sagging timbers are also strong candidates. A new roof with upgraded underlay, fresh battens and dry-fix ridge and verge systems is virtually maintenance-free and adds real value to your home.
