Roof Replacement: 7 Signs You Need a New Roof
If repairs aren’t lasting and leaks keep coming back, a roof replacement (re-roof) may be the safest and most cost-effective option. Here’s how to tell.
Clear Signs It’s Time for a New Roof
- Persistent leaks or water stains – Repeated patch repairs often mean the underlayment has failed.
- Missing, cracked, or curling tiles – UV and weather damage compromise waterproofing.
- Sagging roof deck – Possible structural/moisture issues that require urgent attention.
- Granule loss or worn surfaces – Accelerated ageing and reduced protection.
- Moss and damp inside the loft – Poor ventilation or failing membranes.
- Frequent repairs – If call-outs are increasing, replacement is often cheaper long-term.
- Roof age – Many roofs reach end-of-life at 20–30 years depending on material and exposure.
What Does a Roof Replacement Involve?
A typical re-roof includes a full tear-off, inspection of the deck, installation of breathable membranes, battens, new tiles/slates, flashings, and ventilation. Chimney and valley details are renewed for a watertight finish.
How Long & How Much?
Small houses can be completed in 2–4 days; larger or complex roofs take longer. Costs depend on access, materials (concrete, clay, slate), and condition of the deck. A site visit is the only way to provide an accurate quote.
