Professional Roof Cleaning in Devon
Plymouth and Devon's damp climate makes moss and algae growth a common problem on slate and tile roofs. Our professional roof cleaning service removes moss, lichen, and algae safely, restoring your roof's appearance and preventing long-term damage to tiles and slates.
A clean roof that lasts longer.
Moss and algae aren't just unsightly -- they actively damage your roof. Moss holds moisture against tiles, lifts slates, blocks gutters, and accelerates deterioration. Professional cleaning extends your roof's life and improves your property's appearance.

Same lead tradesman from quote to handover. Site cleaned daily, neighbours considered, and a 25-year guarantee handed over once you're happy.
Does Your Roof Need Cleaning?
Thick Moss Growth
Heavy moss holds moisture against your tiles and can lift slates, leading to leaks.
Green or Black Staining
Algae and lichen growth discolours your roof and can indicate persistent dampness.
Blocked Gutters
Moss debris washing into gutters causes blockages and overflow.
Tiles Lifting or Shifting
Moss roots can get under tiles and gradually lift them out of position.
Reduced Property Value
A mossy, stained roof can significantly reduce your property's kerb appeal and perceived value.
Trade is full of uncertainty. We remove it.

Fully insured · 20 years experience
Two decades of roofing expertise across Plymouth and Devon, fully insured for your peace of mind.
The true cost of cheap work.
Pressure washing a roof yourself or hiring an inexperienced cleaner can cause more damage than the moss.
High-Pressure Damage
Pressure washers strip the protective surface from tiles and can crack slates, shortening your roof's life.
Water Driven Under Tiles
High-pressure water forced upwards under tiles causes leaks and soaks the felt and battens.
Broken Tiles from Walking
Walking on a roof without proper technique breaks tiles. Every broken tile is a potential leak.
No Follow-Up Treatment
Without biocide treatment after cleaning, moss regrows within 6-12 months.
