Moss Emergency · Farnham
Farnham roof — moss emergency done properly
It has probably rained hard for three days, a chunk of moss the size of a shoe has come off the roof and lodged in a gutter, and now water is running down the outside of the wall instead of into the downpipe. Left another week or two, the damp shows up on an upstairs ceiling and the job triples in size.
It has probably rained hard for three days, a chunk of moss the size of a shoe has come off the roof and lodged in a gutter, and now water is running down the outside of the wall instead of into the downpipe. Left another week or two, the damp shows up on an upstairs ceiling and the job triples in size. We deal with this weekly across Farnham and the wider Waverley Borough, and it's genuinely one of the more solvable roof problems if it's caught in the right window.
The typical picture in Farnham
It has probably rained hard for three days, a chunk of moss the size of a shoe has come off the roof and lodged in a gutter, and now water is running down the outside of the wall instead of into the downpipe. Left another week or two, the damp shows up on an upstairs ceiling and the job triples in size.
The sequence that actually works
- Book an external survey the same week so we can see exactly which pitch is shedding the moss.
- Clear the gutter first so any surface water has somewhere to go and the internal damp risk drops immediately.
- Plan a proper moss-scrape and treat visit within the next month, ideally on a dry weather window.
- Add a biocide follow-up so the moss doesn't come straight back and repeat the cycle next winter.
- Check ridge and hip tiles at the same time — heavy moss almost always hides loose ridge bedding underneath.
Red flags — act this week
- damp patches appearing on an upstairs ceiling or top-floor bedroom wall
- moss chunks visible in the gutter or on the ground below the roof
- gutter overflow you can see from indoors during rain
- cracked or slipped tiles becoming visible once the moss has peeled back
Realistic timeline
Emergency gutter clear within days, planned full moss scrape typically within 3–4 weeks depending on weather.
The money reality
A same-week gutter clear plus a planned moss scrape typically costs a fraction of what an internal damp remedy costs once the wall plaster has to come off.
What happens if you ignore it
Water tracks down behind the fascia, hits the internal wall plate, and turns a £400 gutter-and-moss visit into a £2,500 damp-repair job.

Frequently asked
Can you just clear the gutter today and come back for the moss?
Yes — that's actually our preferred order of operations in a moss emergency, because clearing the gutter drops the internal-damp risk immediately. In Farnham specifically, we can normally survey within the week thanks to our regular round through Godalming and Guildford.
How urgent is a moss chunk in the gutter really?
If it's blocking a downpipe outlet during autumn or winter, it's a matter of weeks before you see damp inside — worth acting on the same week. In Farnham specifically, we can normally survey within the week thanks to our regular round through Godalming and Guildford.
Do you cover Farnham for moss emergency situations urgently?
Yes — Same-week bookings when moss chunks are already breaking loose and blocking gutters or downpipes — earlier if internal damp is showing. We prioritise same-week bookings for Farnham when the situation is time-sensitive.
