- Most Surrey homes: once a year
- Near trees / heavy rain: twice a year
- Fascias, soffits & gutters share one schedule
- Blocked soffit vents trap moisture — it's maintenance, not just looks
- Best single slot: autumn (after leaf-fall, before winter rain)
The quick answer: Clean your fascias, soffits and gutters once a year for most Surrey homes, or twice a year if you're near heavy tree cover or get a lot of rain. They're all on the same schedule because the dirt, algae and roof run-off that clog the gutters are the same forces that streak the fascias and green the soffits. The simplest plan is to do the whole roofline in one visit. For a fixed price, call 01737 652 515.
I'm Patrick — a Redhill 2-man crew — and this is the maintenance question we get asked most. Below is the honest schedule, the warning signs your roofline is overdue, why blocked soffit vents are more than a cosmetic problem, and why doing it all in one go saves you money.

How Often, by Situation
There's no single number that fits every house, but the schedule is simple once you know your situation[1]:
| Your situation | Gutters | Fascias & soffits |
|---|---|---|
| Open position, few trees | Once a year | Once a year |
| Near trees / north-facing / damp | Twice a year | Twice a year |
| Heavy overhanging trees | 2-3 times a year | Twice a year |
| Roadside / Gatwick traffic film | Once a year | Twice a year |
Gutters sometimes need clearing more often than the boards if you're under trees, because falling leaves clog them faster than algae stains the fascias. But for most homes, once a year for the whole roofline is the sensible baseline.
Why the Roofline Gets Dirty So Fast
It's easy to forget the roofline because you rarely look up at it — but it takes a battering. Over one to two years, rainwater runs off the roof carrying dirt, pollution and algae spores, dripping off the gutter lip and streaking the fascias. Green algae settles on the shaded, damp soffits. Traffic film lays a grey haze over everything, and leaves and grit silt up the gutters[3]. The result is a house that's otherwise tidy but looks tired from the roofline down.
Signs It's Overdue
- Black tide-line streaks running down the fascias — the classic sign (our black streaks guide explains the cause and fix).
- Green algae coating the soffits, especially on north-facing or shaded elevations.
- Plants or moss visibly growing out of the gutters.
- Water spilling over the gutter edge during rain instead of running to the downpipe.
- Dark or visibly blocked soffit ventilation slots.
If you can tick any of those, you're overdue.
Why Blocked Soffit Vents Matter
This is the bit most people don't realise. The soffit isn't just a tidy board — it usually carries ventilation slots that let air flow into your roof space. When algae and grime block those slots, the airflow is restricted, and moisture gets trapped in the loft[2]. Over time, trapped moisture can lead to damp and even warped or rotting roof timbers.
So cleaning the roofline isn't purely cosmetic. Keeping those vents clear protects the structure above your head. That's the honest reason a regular roofline clean is worth doing even if you don't mind the look of a bit of algae.

The Smart-Bundle Case
Here's where you save money. The costly part of any roofline job is getting the kit set up safely at height — not the cleaning itself. Once we're up there with the water-fed pole and the pure-water tank running, doing the gutter clear, the gutter exterior, the fascias and the soffits together adds very little time.
Book them separately and you pay two call-outs. Book them together and it's one. That's why a combined roofline package nearly always works out cheaper, and why I'll always suggest doing the fascias while we're already clearing your gutters. Our fascia & soffit cleaning cost guide has the full price tables if you want to see the numbers.
Surrey-Specific Factors
A few things push Surrey homes toward the twice-a-year end:
- Tree cover: Surrey's oak-, sycamore- and lime-lined roads drop a lot of leaf litter and shade the roofline, feeding algae and silting gutters.
- Traffic film: Properties near busy roads, the M23/M25 or Gatwick pick up a grey film that greys the boards faster.
- North-facing damp: Elevations that get little sun stay wet and grow algae quicker.
If two or more of those apply to you, plan for twice a year rather than once.
A Simple Yearly Roofline Checklist
- Spring: Look up after the wet winter — check for green soffits and black streaks; treat algae early.
- Summer: Quick visual check after storms; note any overflowing gutters.
- Autumn: The key slot — clear gutters after leaf-fall, clean fascias and soffits, check vent slots, before winter rain arrives.
- Winter: Watch for ice dams or overflow; book early for spring if anything looks blocked.
If you only do one clean a year, make it autumn. If you do two, add spring.

How often should you clean fascias, soffits and gutters?
Once a year for most Surrey homes, and twice a year if you're near heavy tree cover or get a lot of rain. The roofline and gutters share a schedule because the same dirt, algae and roof run-off affect both.
How do I know if my roofline is overdue a clean?
Black tide-line streaks down the fascias, green algae on the soffits, plants growing in the gutters, water spilling over the gutter edge in rain, or dark/blocked soffit vents all mean it's time.
Why do blocked soffit vents matter?
They let air into the roof space. When grime blocks them, airflow is restricted and moisture gets trapped in the loft, which over time can cause damp and warped roof timbers. It makes cleaning a maintenance job, not just a cosmetic one.
Should I clean fascias and gutters at the same time?
Yes — it's tidier and cheaper. The crew is already at roofline with the same kit, so doing it all in one visit means one call-out instead of two, and a combined package usually costs less than separate jobs.
What time of year is best?
Autumn after leaf-fall is the best single slot, clearing gutters before winter rain. Spring is good for tackling algae after a damp winter. Twice a year means autumn plus spring.
