Roof Moss Removal in Northampton

A light dusting of moss on a roof is normal, especially on shaded pitches near trees. The trouble starts when it thickens into a carpet. That carpet soaks up rain like a sponge and holds it against the tile long after the sky has cleared. In winter the trapped water freezes, expands and works at the tile from the edges until small cracks become missing corners.

The second problem is gravity. Every shower of rain washes loose moss down into the gutters, and a gutter packed with moss holds water against the fascia and eventually overflows down the wall. Half the damp patches we are called to in Northampton trace back to gutters that were fine until moss season filled them.

Clearing it by hand deals with both. We lift the moss off without blasting the tile surface, flush the gutters through while we are up there, and photograph the roof so you can see the difference. If you want a protective coating to slow regrowth, we quote it separately and you decide.

Timing-wise, moss is easiest to deal with in a dry spell, when it is brittle and the roof surface is not slick. We work safely through most of the year, but a dry autumn or spring clearance means the gutters stay cleaner for longer afterwards, and any protective coating cures properly rather than fighting the rain. If a winter storm has already packed your gutters with moss, we can clear those first and schedule the roof for the next dry window. And if clearance shows the tiles themselves are past their best, the full range of work is on our Northampton roofers page.
