Question 1

How much does roof cleaning cost?

Accepted Answer

Cost depends on the size of the roof, its condition, the material and how accessible it is. That is why quotes are given after your details (and ideally a few photos) have been reviewed — and the quote itself is always free with no obligation.

Question 2

Can old roofs be cleaned?

Accepted Answer

Many older roofs can be cleaned, but not all. Period roofs are assessed first: the age, material and condition decide whether cleaning is appropriate and which method is suitable. If a roof shouldn't be cleaned, you'll be told.

Question 3

Can slate roofs be cleaned?

Accepted Answer

Slate is often one of the most rewarding materials to clean because the original colour is usually still underneath. Slate is normally treated with gentle, appropriate methods rather than aggressive washing.

Question 4

Will roof cleaning damage tiles?

Accepted Answer

Damage risk comes from using the wrong method on the wrong roof. A professional assesses the roof first and chooses a cleaning method suited to its material and condition. Fragile or worn roofs are treated far more gently.

Question 5

Do you pressure wash every roof?

Accepted Answer

No. Pressure washing is not appropriate for every roof. Depending on the roof, soft washing, treatment or manual moss removal may be far more suitable. The method always depends on the roof.

Question 6

How long does roof cleaning take?

Accepted Answer

Most domestic roofs are completed within a day, though larger, steeper or heavily covered roofs can take longer. Your quote will include an estimated timescale.

Question 7

Do I need scaffolding?

Accepted Answer

Not always. Some roofs are cleaned from the ground or with roof ladders and safety equipment. Scaffolding is only used where it is required for safe access.

Question 8

Will moss grow back?

Accepted Answer

Organic growth can return over time, especially on shaded or north-facing roofs. Treatments can slow regrowth considerably, and many homeowners have their roof checked every few years.

Question 9

Do I need to be home?

Accepted Answer

It helps for the initial visit and for access, but it isn't always essential. Arrangements are agreed with you before any work starts.
