Key takeaways

Black streaks are algae, not dirt.

Moss holds water against tiles and lifts them.

A clean roof can delay a costly replacement.

Roofs age quietly. By the time a problem is obvious from the street, it’s often been building for years. These are the five signs we look for.

What to look for

  • Black streaks running down the slope.

  • Green or yellow patches of moss and lichen.

  • Gutters full of grit and moss.

  • Tiles that look lifted or uneven.

  • Damp patches inside the loft.

Why it matters

Moss acts like a sponge. It holds water against the tiles, which freezes and expands in winter and slowly cracks them. Cleaning it early is far cheaper than repairs.

We never pressure wash a roof. A low-pressure treatment kills growth safely and keeps working for months after we leave.
