Fascias and soffits are the boards that close off the edge of your roof and carry the guttering. They are the part of the roof people notice last and the part that fails first, because they sit directly behind a gutter that has probably been overflowing for years. Most of the roofline enquiries we take start with a sagging gutter rather than a rotten board, but the board is usually the reason.
Roofline replacement done properly: rotten timber removed rather than capped, with matching gutter renewal.
What each part actually does
The fascia is the vertical board fixed to the ends of the rafters. It takes the weight of the gutter and everything the gutter is carrying, which in a heavy shower is a surprising amount of water.
The soffit is the horizontal board underneath, closing the gap between the fascia and the wall. It keeps birds and wasps out of the roof void while allowing ventilation through vents or a continuous strip. Block that ventilation and you trade a roofline problem for a condensation problem.
Bargeboards do the same job at the gable end, where there is no gutter but plenty of exposure to wind driven rain.
How we tell whether boards need replacing
We probe rather than guess. Softness at the joints, flaking paint that lifts in sheets, dark staining down the wall behind the gutter and a gutter line that dips between brackets all point the same way.
Gutter sagging or pulling away from the wall
Paint blistering or peeling repeatedly after redecoration
Green or black staining on the wall directly below the gutter line
Birds getting into the roof space at the eaves
Soffit boards bowing downwards or showing daylight gaps
Screws and brackets that no longer bite into solid timber
Why we do not cap over rotten timber
Capping is the practice of screwing a uPVC cover board over the existing timber. On genuinely sound timber it is acceptable. On soft or wet timber it is a cosmetic fix that seals moisture in and leaves the rot to carry on out of sight, usually reaching the rafter ends within a few years.
Our default is full replacement: old boards off, rafter ends inspected and treated or spliced where needed, new boards fixed back to sound timber, ventilation reinstated and new gutter hung to a proper fall.
uPVC is the practical default on most twentieth century housing. It does not rot, it needs washing rather than painting, and it comes in enough finishes to look right on a modern semi.
Painted timber still has a place on period and conservation area frontages, where the profile and shadow line of a timber board matters and a plastic board would look wrong. It costs more over its life because it needs repainting, and we will say so up front rather than after the job.
How long does a full roofline replacement take?
On a typical three bedroom semi, two to three working days once access is up. Larger detached properties or jobs with significant rafter end repair take longer.
Do I need scaffolding for fascias and soffits?
For a single storey run a mobile tower is often enough. For a full two storey perimeter, scaffolding is safer and usually works out cheaper than repeatedly moving a tower.
Will new soffits stop my loft breathing?
Not if they are fitted correctly. We reinstate eaves ventilation with vented soffit or continuous strip vents, because sealing a loft up causes condensation and damp timber.
Can you replace guttering at the same time?
Yes, and it is the sensible way to do it. The access is already there, so combining the two avoids paying for scaffold twice.
Do you match existing colours?
Yes. White, black, anthracite grey, rosewood and light oak are all readily available, and we can match most existing rooflines closely.
We check the boards, the rafter ends behind them and the gutter falls, then photograph anything you cannot see from the ground.
Itemised for materials, labour and access, with the ventilation detail stated so you know it is included.
Old boards come off and rafter ends are examined. Any splicing or treatment needed is agreed before we fit new.
New fascia, soffit and bargeboard fitted to sound timber with continuous or vented eaves airflow retained.
New gutter hung to fall, joints checked, then flushed with water so you can see it runs before we leave.
