High-Pressure Jet Wash or Soft Wash?

• Your roof is not felted, the felt is poorly constructed, or the felt has significantly deteriorated
• Your roof is made up of clay tiles or slate (other types may fall into this category)
• The roof is over 50 years old
We appreciate that it can be difficult for you to know whether your roof is in a good condition or not. A quick scan by a member of our team can quickly identify the general state of the roof, with a more rigorous inspection showing up major issues. If we are in any doubt whatsoever about the suitability of a pressure wash, we will use a soft wash method to eliminate the unnecessary risk of further damage.
