Eastleigh is 1950s–70s post-war concrete tile housing stock with nail sickness. Valley and riverside Eastleigh properties need biocide retreatment every 3–5 years. Chalk ridge properties every 5–7 years. We recommend zinc strips to extend the treatment interval.

Professional biocide spray treatment does not damage tiles, slates or mortar. We do not use pressure washing — the force damages period tile surfaces and mortar joints. Biocide kills moss at the root; dead material weathers off without mechanical force.

Consumer-grade biocide products have lower active concentrations than professional equivalents. Getting safely onto a Eastleigh domestic roof requires correct access equipment. We carry out free surveys — there is no reason to attempt DIY roof access on any Eastleigh property.

Yes — gutter clearing is included as standard with every moss treatment visit. After biocide treatment, dead moss washes into gutters over 2–4 months and must be cleared to prevent blockage. We include a follow-up gutter clear in the post-treatment package.

Yes — biocide treatment prevents regrowth for 3–7 years depending on the roof aspect and local environment. North-facing pitches in Eastleigh near trees or the Itchen corridor recolonise faster than south-facing chalk ridge properties. Zinc ridge strips significantly extend the inhibition period.

No — moss growth is a maintenance issue excluded from buildings insurance policies. Some insurance assessors note heavy moss growth as a contributing factor to underlying roof failures which may affect claim settlements. Regular professional treatment is the correct approach.

Autumn (September–November) before peak moss growth season is ideal. Spring treatments before summer sun accelerate the weathering of dead material. We carry out moss treatment year-round in Eastleigh — dry days in winter are entirely workable.

Yes — every moss treatment visit includes a written roof condition report at no extra charge. We inspect tile condition, lead flashings, ridge mortar and gutter condition while on site. This is included as standard, not an optional extra.
