Repair or Replace? Making the Right Decision
This is one of the most common questions we hear from West London homeowners. The answer depends on several factors – here's how to make the right choice for your property.
When Repairs Make Sense
Localised Damage
If damage is confined to a small area – a few slipped slates, a damaged flashing, or a section of guttering – repairs are usually the sensible choice.
Younger Roof
A roof less than 15 years old with isolated problems is a good candidate for repairs. The underlying structure and majority of materials still have plenty of life.
Budget Constraints
Quality repairs can buy you years while you save for eventual replacement. However, don't let short-term savings lead to long-term problems.
Single Issues
One problem at a time – a leak after a storm, or a damaged chimney – usually warrants repair rather than replacement.
When Replacement is Better
Age
Most roofing materials have a finite lifespan:
If your roof is approaching these ages and having problems, replacement makes sense.
Multiple Issues
When you're facing several problems simultaneously – tiles, flashings, gutters, and chimney all need work – replacement may be more economical than multiple repairs.
Failed Underlays
The felt or underlay beneath your tiles keeps water out when tiles fail. If this has deteriorated, replacing tiles alone won't solve your problems.
Structural Concerns
Sagging ridges, spreading rafters, or rotten timbers indicate structural issues that often make replacement necessary.
Energy Efficiency
Older roofs often lack modern insulation. Replacement provides an opportunity to improve energy efficiency significantly.

The 30% Rule
As a general guide: if repairs would cost more than 30% of replacement cost, consider replacing instead. You'll get a new roof with guarantees rather than patching an ageing one.
