Roof cleaning and moss treatment in Plymouth

Moss and grime change how a whole building reads from the street — and on flat roofs the build-up can go unnoticed for years because nobody sees it.

We’ve cleaned and moss-treated roofs in Plymouth, including a salon’s flat roof where the customer praised the visible result, the communication and the tidy finish. The right process depends on the roof type and its condition.

Salon roof clean

We recently had our salon flat roof pressure washed and treated for moss, along with the rear of the property, and I’m really pleased with the results. Everything looks noticeably cleaner and well maintained. Professional, reliable service with great communication throughout, and everything was left tidy afterwards. Would definitely recommend and will be using again.

Roof cleaning questions

Do you pressure wash every roof?

No single method suits every roof — some coverings should not be pressure washed at all. We choose the approach after looking at your roof, and we will tell you plainly if a roof is not a good candidate.

How do you treat moss?

Moss treatment depends on the roof type and how established the growth is. The process for your roof is confirmed as part of the quote.

Will you clear the gutters afterwards?

Roof cleaning and gutter clearing go naturally together, since dislodged moss tends to end up in the gutters. Ask for both in one visit.

Will the moss grow back?

All roofs regrow moss eventually — shade, trees and coastal weather all play a part. We will give you a realistic expectation for your roof rather than a guarantee we cannot stand behind.

Not sure what your roof needs?

Send a short description and a few photos if you have them. We’ll confirm whether the job is a good fit and arrange the next step.
