Your roof takes a beating from British weather every year. Most roofs are surprisingly resilient — but small problems can become serious ones quickly if they're missed.
Here are the warning signs it's time to call a roofer.
1. Water stains on ceilings or walls
Yellow, brown, or damp patches on ceilings and upstairs walls are one of the clearest indicators of a roof leak. Even small stains can mean water has been getting in for a while.
2. Missing, slipped, or cracked tiles
Take a look at your roof from the ground on a bright day. Any tile that looks out of place — sitting too low, missing entirely, or visibly cracked — is a potential entry point for water.
Storms in particular can dislodge tiles. If a strong wind has just passed through, it's worth a quick check.
3. Sagging areas
A visibly sagging roof is a serious warning sign. It usually indicates structural issues, wet timbers, or long-term water damage. Don't wait — get this looked at by a professional.
4. Granules from tiles in your gutters
Roof tiles have a protective coating that can wear away over time. If you're noticing small grit-like granules building up in gutters or on the ground below the downpipe, your tiles may be nearing the end of their life.
5. Damp or musty smells in the loft
Head into the loft with a torch. If it smells damp or musty, or you can see:
- Wet timbers
- Mould or mildew
- Discoloured insulation
...there is very likely moisture getting in from above.
6. Daylight through the roof
While you're in the loft, turn off the torch and look up. Any daylight visible through the roof means water can get through too.
7. Blocked or overflowing gutters
Gutters overflowing during heavy rain don't just damage your walls — they push water back under the eaves, where it can rot timber and get into the roof structure. Get them cleaned regularly.
8. Damaged flashing around chimneys
Lead flashing around chimneys is a very common leak point. Look for lifted, split, or missing sections of lead. This is a job for a professional — lead work needs to be done properly to last.
9. Higher heating bills
A tired roof with worn insulation or poor ventilation loses more heat. Sudden jumps in your heating bills without other explanations can sometimes point to roof issues.
10. Your roof is over 20 years old
Age alone isn't a problem — a well-maintained roof can last 40–60 years — but older roofs need more attention. If yours is more than two decades old and hasn't been inspected recently, it's a good idea to have a professional take a look.
