Your soffit is the intake vent for your entire attic. When it’s blocked or damaged, the moisture problem moves inside.
Most people think of soffit as the panel that closes off the underside of the roof overhang. Cosmetic. Something that matches the fascia.
It’s actually doing a job. Air enters your attic through the soffit vents and exits at the ridge or through roof vents near the peak. That flow is what carries moisture out of the attic. Warm damp air rises out of your living space, gets into the attic, and if there’s nowhere for it to go, it condenses on the cold underside of the roof sheathing.
In Surrey, where it’s cool and wet for five months of the year, that condensation is a real problem. It shows up as dark staining on the sheathing, damp insulation, and eventually mould. Homeowners usually blame a roof leak. Often there’s no leak at all, just an attic that can’t breathe. Blocked soffit is one of the most common causes we run into, and it’s one of the easiest to miss because the block is usually invisible from the ground.
We work in vinyl, aluminum and fibre cement soffit, and we install vented, solid, or a mix depending on what your roof actually needs.
That last part matters. Not every soffit run should be vented. Where a lower roof meets an upper wall, or where an eave is enclosing conditioned space, venting in the wrong place can pull moist air into the assembly instead of out of it. We look at the whole roof before deciding.
For a standard overhang, we install continuous vented soffit and make sure the free air space is genuinely open. That means checking behind it, not just fastening the panel and moving on. We also handle the soffit-to-fascia transition and the soffit-to-wall junction, including the return where the eave meets the siding. Those two joints are where birds get in, and where a lot of installers leave a gap and call it done.
What we don’t do: attic insulation, roof vents, and gutters. If your problem turns out to be insulation blocking the eaves or a ridge vent that was never cut open, we’ll tell you exactly what we found so you can get the right trade in.
We get a steady run of calls in spring about something living in the eaves.
Starlings nesting in siding and eave crevices across the Lower Mainland is usually a sign of aging cladding that’s opened up enough to let them in. Once they’re in, the nesting material blocks the vent path and holds moisture against the wood, often compromising your home’s moisture protection.
The fix isn’t just closing the hole. It’s replacing the soffit and exterior trim that failed and closing the return properly at both ends, so the next bird finds a flat panel instead of a gap.
Same story with wasps. A nest in an open eave means there’s a cavity that shouldn’t be accessible.
One practical note: if there’s an active nest with young birds in it, timing matters, because many species are protected under federal and provincial wildlife rules. We’ll work around it and schedule the repair for after they’ve fledged rather than putting you in an awkward position.
A lot of the homes we work on in Cloverdale, Newton, Fleetwood and Guildford were built between 1980 and 2000, with the original painted plywood or wood soffit still up there. On those houses we usually find one of two things. Either the soffit has been repainted so many times that the venting is closed, or the plywood has delaminated at the edges where it meets the fascia and water has been getting in.
There’s a third scenario worth mentioning. If the fascia has rotted, which often requires comprehensive wood rot repair, the soffit is almost always compromised too, because they share a joint and the same water. We’d rather do both at once than have you pay for scaffolding twice.
Newer builds in Clayton Heights and East Clayton generally have vinyl or aluminum soffit that’s holding up fine. Problems there tend to be panels blown loose in a windstorm or a section damaged by a ladder.
Soffit is quoted by the run, and it’s usually priced alongside fascia because the two go together. Everything else works the way it does on all our jobs. Free inspection by appointment. No deposit.

No. We install and repair soffit, fascia, trim and siding. Attic insulation, ridge vents and roof vents are different trades. If your soffit is fine but insulation is blocking the eaves, we’ll tell you that on the inspection so you’re not paying us to fix the wrong thing.
It depends on the run. Most standard overhangs should be vented so air can move through the attic. But where a lower roof meets an upper wall, or where the eave encloses heated space, venting can do more harm than good. We look at the whole roof before we decide, rather than defaulting to vented everywhere.
Yes, if the rest of the run is in good shape and we can match the profile. Matching older vinyl and aluminum soffit isn’t always possible, and we’ll be upfront if we think a patch will look obvious. For wood soffit, section repairs are usually straightforward.
We can, but timing matters. Many nesting birds are protected under federal and provincial wildlife rules, so if there’s an active nest with young in it, we’ll schedule the repair for after they’ve fledged. In the meantime we can quote the work and get you booked.
Usually, and we’d recommend it. They share a joint and take the same water, so when one has failed the other is normally close behind. Doing both in one visit also means you only pay for access and staging once.
Late May through September gives the most reliable dry stretch in the Fraser Valley, which matters because the eave is open while we work. We do take urgent calls outside that window and plan around dry days when we do.
