The Repair Versus Replace Question

This is a question homeowners face regularly, and the honest answer is rarely straightforward. A roof that is 20 years old and has one slipped tile almost certainly needs only a repair. A roof of the same age with widespread mortar failure on every ridge and hip, multiple cracked tiles and a felt layer that has turned brittle and begun to split is approaching the end of its useful life - and patching it is likely to cost you more over five years than replacing it would have done today.

The difficulty is that most homeowners cannot tell which situation they are in without getting someone up on the roof to look properly. A quick check from the guttering level will not reveal the condition of the felt, the state of the batten timbers or whether the flashings have been correctly installed.

When a Repair Makes Clear Sense

There are situations where repair is unambiguously the right choice. A repair is the correct option when:

• The problem is isolated - a single broken tile, one lifted section of flashing, or a small area of failed mortar on a ridge section.
• The surrounding tiles and felt are in good condition and have reasonable life left in them.
• The roof is less than 15 years old and has not had significant previous repairs.
• Storm damage has affected one part of the roof but the rest is sound.
• The flashing around a chimney or parapet has failed but the tiles themselves are fine.

In these cases, a targeted repair carried out with the correct materials will extend the roof's life without the cost and disruption of a full replacement. Roof repairs in Horsford typically cost between £150 and £600 for most standard jobs - a slipped tile and re-pointing, a flashing remake, or a small area of felt repair on a flat roof section. More complex work involving scaffold and a full chimney rebuild will cost more, but is still far below a full re-roof.

When Replacement Starts to Make More Sense

A roof reaches the point where repeated repairs become poor value. Signs that replacement deserves serious consideration include:

• Multiple tiles cracking or slipping across different parts of the roof, not just one section - this often indicates that the nibs (the hooks that hold tiles to the batten) have become brittle and are failing throughout.
• Felt that has perished across a wide area. Once the underlay is gone, the roof is relying on the tiles alone to keep water out, which is not what they are designed to do.
• Battens that have rotted. If battens are soft or broken, tiles cannot be secured properly no matter how many times the mortar is renewed.
• A roof that has been repaired several times in the last ten years and is still leaking in new places.
• Original asbestos cement sheets on an outbuilding or extension - these require licensed removal before any other work can take place.

A full re-roof on a typical three-bedroom semi in the Norwich area generally costs between £5,000 and £10,000 depending on the pitch, the tile type chosen and whether scaffold is needed on both sides. This is a significant outlay, which is exactly why it is worth getting an honest assessment of whether repair will genuinely extend the roof's life before committing to either route.

What the Inspection Should Tell You

A good roofer will not tell you whether to repair or replace until they have been on the roof and checked several things. The condition of the underfelt matters as much as the tiles. The state of the battens - whether they are holding fixings properly, whether they are damp or showing signs of rot - is crucial. The flashings around any chimney, soil pipe, skylight or parapet wall should be checked separately, because flashing failure is often the real cause of a leak even when the tiles look intact.

Ask the roofer to tell you what they found, not just what they want to charge. A breakdown of findings - which areas are sound, which need attention now and which might need attention in the next few years - gives you useful information whether you decide to repair or replace.

Flat Roof Sections - a Different Calculation

Many homes have a flat-roofed extension, porch or garage. Flat roofs have a different lifespan calculation to pitched roofs. A well-installed EPDM rubber flat roof can last 30 years or more. A felt flat roof installed without adequate falls, or where the seams have been poorly finished, may fail in under a decade.

For flat roofs, the repair-versus-replace question often comes down to the number of layers already present. Building regulations limit flat roofs to two layers of felt before a full strip is required. If a flat roof already has two layers and is leaking, replacement is the only compliant option. A single-layer felt roof with localised blistering or a split seam is usually repairable if the rest of the surface is sound.

EPDM rubber is worth considering when a flat roof is being replaced. It is a single-ply membrane that does not require the multiple-layer build-up of traditional felt, and when properly detailed at the edges and upstands, it performs well in variable weather.
