Typical roof lifespans by material, the signs a Medway roof is nearing the end, and how estuary weather shortens the clock.
A well-installed roof should last decades, but Medway's estuary weather shortens the lifespan. Here's how to tell if yours is nearing the end.
Typical Lifespans
- Concrete interlocking tiles: 40–60 years
- Clay and Kent peg tiles: 60–100+ years
- Slate: 75–150 years
- Felt flat roof: 10–20 years
- EPDM/GRP flat roof: 30–50 years
Signs You Need A New Roof
- Sagging roofline — visible dip in the slope suggests structural issues
- Daylight through loft boards — if you can see light through the roof, water can get in
- Excessive moss and crumbling tiles — tiles losing their surface granular coating
- Repeated leaks — if you're patching leaks every year, replacement is cheaper long-term
- Neighbours are re-roofing — terraced homes in Gillingham, Luton and Chatham were often built at the same time
The Medway Difference
Salt air and prevailing winds accelerate wear, especially on homes in Rainham, Walderslade and the Hoo Peninsula facing the estuary. We factor this in when advising on materials.
Re-roofing adds value and peace of mind. We offer free, honest assessments — if your roof has years left, we'll tell you. For a no-obligation quote in Chatham, Rochester, Gillingham, Strood, Rainham or Walderslade, call today.
