Gutters, Fascia & Soffit
Why Fascia & Soffit Cleaning Isn’t Part of a Roof Clean
The short version
- Gutter clearing is part of a roof clean. Fascia and soffit cleaning is not.
- They are different jobs, done differently, on a completely different material.
- A roof clean can leave the roofline looking worse, because the roof above it just got cleaner.
- Left long enough, UPVC oxidises, and at that point cleaning can only do so much.
This is the most common misunderstanding we deal with, and it is an entirely reasonable one. The roof, the gutters and the roofline are all up there together, so it seems natural that cleaning one covers the others. It does not, and it is better to know that before the work than after it.
What is and is not included
A roof clean includes clearing the gutters. That is not generosity, it is necessity: a lot of material comes off a roof and it has to end up somewhere, so leaving it packed into the gutters would simply move the problem down a level. A ridge check is part of it too.
Fascia and soffit cleaning is a separate service. So is window cleaning, and conservatory roofs sit with window cleaning rather than with roof cleaning, which surprises people just as often.
Why they are genuinely different jobs
A roof is tile or slate: a hard, weather-facing surface, cleaned by removing growth in whatever way that tile can take and then treating the whole plane.
Fascia and soffit are coated plastic, usually UPVC. The problem is not moss but a film of atmospheric grime, algae in the shaded and sheltered spots, and staining where water has been running over the same place for years. Pressure is the wrong approach entirely: it marks the plastic and drives water up behind the boards into the roof space, which is the one place you do not want it. It is close work, by hand, with the right cleaning agents.
Different material, different problem, different method, different time on site. That is why it is priced as its own job rather than folded into another one.
Same ladder, same afternoon, completely different job.
Why a roof clean can make the roofline look worse
This catches people out, and it is worth being upfront about it. Before the work, the roof and the roofline are both weathered, and the eye reads them as one thing.
Afterwards there is a clean roof directly above a set of boards that have not been touched. Nothing has happened to the fascia, but the contrast is now obvious, and it will be more obvious than the owner expected.
There is a practical reason too. Roof runoff carries what is on the roof down over the roofline, so the boards under a mossy roof have been taking dirty water for years. Once the roof is clean, that stops, but the accumulated staining is still there.
What happens to UPVC when it is left
UPVC does not stay pristine. Sunlight and weather gradually degrade the surface, and the finish chalks and dulls, which is usually described as oxidation. Once the surface has genuinely oxidised, cleaning removes the dirt but cannot fully restore the finish, because the finish itself has changed.
That is the honest limit of what cleaning does. Caught reasonably early, roofline cleaning brings the boards back close to how they should look. Left for many years, it will be a clear improvement but not a restoration, and anyone promising otherwise is overselling.
What roofline cleaning does not fix
It is cleaning, not repair. It will not fix rotten timber behind the boards, and it will not solve a ventilation problem in the roof space. It will not repair a sagging gutter or a leaking joint, and it will not stop a blocked gutter from overflowing.
What it will do is make problems visible. Boards that stay stained after cleaning, or that flex when worked on, are telling you something, and we would rather point that out than paint over it.
Booking them together still makes sense
Separate jobs, but they belong in the same visit. Access is already set up, the roofline is exactly where the roof debris lands, and doing the roof first means the boards are cleaned after the dirty runoff has stopped rather than before.
We also run a discount for booking more than one service, so the practical answer for most properties is to do the roof, the gutters and the roofline together and have the whole thing consistent. Ask us and we will tell you what makes sense for your property rather than quoting the lot as standard.
Common questions
Is fascia cleaning included in a roof clean?
No. Gutter clearing is included, because roof debris has to go somewhere. Fascia and soffit cleaning is a separate service on a different material with a different method.
Can UPVC go back to white?
Often close to it, if it has not been left too long. Once the surface has genuinely oxidised, cleaning removes the dirt but cannot fully restore the original finish.
Will cleaning damage the fascia?
Not when it is done properly by hand at low pressure. Damage comes from pressure washing UPVC, which marks the surface and can force water up behind the boards.
Should the fascia be done before or after the roof?
After. Cleaning the roof sends debris and dirty water down over the roofline, so doing the boards first means doing them twice.
What about the conservatory roof?
That sits with window cleaning rather than roof cleaning. Mention it when you enquire and it can be handled in the same visit.
