Roof cleaning across Aintree
Slate and interwar concrete tile are too porous to blast, so every Aintree roof gets a gentle soft wash and a moss treatment that keeps working long after we have packed up.
Aintree sits on some of the flattest ground on Merseyside, the old mossland of the River Alt basin, and the Leeds and Liverpool Canal cuts through it right past the racecourse. Flat ground drains slowly, the canal corridor holds a band of damp air, and the mature street trees and privet hedges planted with the 1930s avenues throw shade across roofs and drives for half the day. Put those together and moss, green algae and black spot come back on Aintree’s tiles, flags and dashed walls season after season until the growth is treated properly rather than just rinsed off.
