Moss on a Sunderland roof usually grows thickest on the side facing away from the sun and the sea breeze, where tiles stay damp. Thick cushions are scraped off first, because no wash reaches the tile through a saturated layer.
What is left is cleaned with a soft wash, a low pressure wash or hot steam, chosen for the tile. High pressure is never used on roof tiles. The fallen moss is gathered from the gutters and ground, then a treatment goes on to slow regrowth.
Roofs close to the coast can look clean on one slope and green on the other, so we price each slope on what we actually see.
Questions about roof cleaning in Sunderland
Will you use a jet wash on my tiles?
No. We use a moss scrape, soft wash, low pressure or hot steam, never high pressure.
Do you clear the gutters after?
Moss that lands in the guttering is collected up as part of the roof job.
