Guttering are the parts of a roof that fail first, most cheaply, and with the biggest consequences elsewhere in the property. The main tiles or slates are protected from most weather because water runs off them quickly. The gutters and fascia boards, by contrast, hold water, trap debris, and sit exposed to sun, wind and rain year-round. A guttering system that has been ignored for a decade is a slow leak into the fabric of the house.

Most Bournemouth Roofer homes have either uPVC guttering, installed in the last few decades and generally reliable, or older cast iron guttering on Victorian and Edwardian properties. Cast iron gutters, when maintained, are excellent – they are heavier and less prone to sagging than plastic, and they can be repaired rather than replaced. When neglected, they rust from the inside, drop sections without warning, and are expensive to match if only one length needs replacing. Plastic guttering is cheaper to maintain but has a shorter useful lifespan and becomes brittle in UV over about twenty years.

By far the most important guttering maintenance job is clearing debris twice a year – once in late autumn after most of the leaves have fallen, and once in spring to remove anything the winter blew in. A gutter half-full of leaves and moss cannot drain properly. Water backs up, overflows down the fascia, and finds its way behind the fascia board into the wall cavity. Within a season, the fascia rots and the wall shows damp inside. Every hour spent cleaning gutters saves ten hours of remedial work on the fabric of the house.

Fascia boards are the timber or plastic boards that run horizontally along the eaves, hiding the ends of the rafters. Soffits are the boards underneath, hiding the joint between the wall and the roof line. Both are exposed to weather and both fail if the guttering above them fails. Timber fascias, once wet, rot slowly and invisibly – by the time paint is peeling and the wood is visibly soft, the damage has been there for a year or more. uPVC fascias do not rot but they can discolour, and if the fixings behind them have gone into rotten timber, they will pull loose in a storm.

Replacing a fascia and soffit is a bigger job than most homeowners expect, and one that only makes sense in the context of a wider look at the roof. The old fascia is removed, the ends of the rafters are inspected and cut back if rotten, a new fascia is fitted and secured to sound timber, and new guttering is hung from it. Doing the fascia without checking the rafter ends is how a job comes back within a few years – the new fascia is fine but the timber it is fixed to has already gone. Any roofer worth using will inspect and replace rafter ends where needed rather than hide the problem behind new plastic.

Downpipes are the least glamorous part of the whole system and the one where debris causes the most trouble. A blocked downpipe backs up the whole guttering above it. The blockage is often invisible from the ground because it sits inside the pipe at a joint. A quick way to check is to run a hose into the gutter and see how quickly it drains. If it takes more than a few seconds to clear, there is a blockage somewhere in the run.

The practical minimum every autumn is straightforward. Clear the gutters. Check the downpipes drain freely. Look for any water staining on brickwork or peeling paint on fascia boards below any gutter section. Address anything that looks wrong before winter properly sets in. Ten to fifteen minutes on each side of the house in November keeps the whole roof line healthy through the wet months and prevents most of the damage that expensive remedial work has to reverse in spring.
