Signs You Need a New Roof
By the Quantock Roofing team · Updated 14 June 2026
Most roofs give plenty of warning before they fail completely. Knowing the signs helps you act before a small problem becomes an expensive one — and tells you whether you're looking at a repair or a replacement. Here's what we look for.
Warning signs to look out for
From the ground (don't climb up to check), or from photos, these are the common signs a roof needs attention:
- • Slipped, cracked or missing tiles or slates
- • Sagging or dipping in the roof line
- • Damp patches or staining on bedroom ceilings
- • Daylight visible through the roof in the loft
- • Crumbling or missing mortar at ridges and verges
- • Lots of granules from tiles collecting in the gutters
- • Repeated leaks despite previous repairs
Repair or replace?
A few slipped tiles or a single leak usually means a repair — there's no need to replace a sound roof. Widespread failure across the whole covering, failed underlay, or repairs that no longer hold, usually point to a re-roof being better value.
The honest answer depends on the roof. A good roofer should be happy to explain the reasoning either way rather than jumping straight to the most expensive option.
Age is a guide, not a verdict
Different coverings last different lengths of time, and exposure, ventilation and installation quality all play a part. Age alone doesn't condemn a roof — but an older roof showing several of the signs above is worth getting inspected.
Get an honest assessment
If you're seeing any of these signs, a roof inspection gives you a clear, honest view of the roof's condition and whether anything needs doing now. We'll tell you straight whether a repair will do or a replacement is the sensible call. Send photos on WhatsApp for a quick steer, or book an inspection.
