What fascias and soffits are
The fascia is the board that runs along the edge of the roof and holds the gutter; the soffit is the panel underneath it, closing off the gap between the wall and the roof edge. Both are usually UPVC or timber on homes in the Portsmouth area and both show dirt and algae staining over time.
Why they get stained
Overflow from blocked gutters runs straight down the face of the fascia, and general airborne grime and algae settle on soffits in the same shaded, damp conditions that encourage moss on the roof above.
How they're usually cleaned
Most installers clean fascias and soffits with a soft-brush wash and a cleaning solution suited to UPVC or painted timber, rather than a high-pressure jet that can damage the surface or force water behind the boards.
Doing it alongside other roofline work
Because the access equipment for a roof clean or gutter clear usually reaches the fascia and soffit anyway, many homeowners have all three done in the same visit. Ask the installer you're matched with whether that's how they'd price it.
Frequently asked questions
Can UPVC fascias be pressure washed?+
Ask the installer — many prefer a lower-pressure wash for UPVC to avoid forcing water behind the boards or damaging the surface finish.
Will cleaning fix staining from a gutter that's been overflowing for a while?+
It should lift most surface staining. If the overflow has been going on for a long time, mention that in your enquiry so the installer knows what to expect.
Is this normally sold separately from gutter clearing?+
It varies by installer — some price it as part of a roofline package, others separately. Ask when they quote.
