Roofline Costs Explained
The Full Roofline Picture in Perth
Bargeboards and the Gable End
The roofline is not just the eaves — the gable ends carry bargeboards, the sloping boards that finish the verge, and these are often the worst-affected timber on a Perth property. Exposed on the gable to driving rain, softwood bargeboards rot from the back and at the apex where water collects. On the exposed estate housing around Perth's edge, failed bargeboards are a common sight. A full roofline quote includes the bargeboards, not just the front fascia — leaving rotten bargeboards while replacing the fascia is a half-job that looks odd and keeps letting water in.
Aluminium vs uPVC in Perth
For most Perth estate housing, quality uPVC roofline is the sensible, cost-effective choice — maintenance-free and long-lasting. But on the Victorian and Edwardian properties of Kinnoull and Bridgend, and on exposed elevations taking the full weather, cast or extruded aluminium is worth the premium. Aluminium holds a crisp profile, takes paint, resists impact, and lasts longer than uPVC on a punished elevation. The right material depends on the property and its exposure — we advise honestly rather than fitting the same uPVC everywhere regardless.
Colour, Guttering Size and Downpipes
A roofline replacement is the moment to get the guttering specification right for Perthshire rainfall. Undersized guttering overflows in the heavy downpours the region sees; we size the guttering and downpipes to the roof area draining into them, often upgrading from the minimal original spec. Colour matters too — black and anthracite grey suit most Perth properties and are the common choices, with white now less popular. Getting size, colour, and downpipe positions right as part of the roofline job avoids a mismatched, overflowing system later.
Half-Round vs Ogee Guttering
Guttering choice affects both cost and performance on Perth properties. Half-round guttering is the standard, cost-effective option and suits most estate housing. Ogee (or "squareline") guttering has a larger capacity and a more traditional profile that suits period properties, at slightly higher cost. On the exposed western Perth estates that see heavy downpours, capacity matters — undersized guttering overflows regardless of how clean it is, so we size the guttering to the roof area, not just replace like-for-like.
Downpipes and Drainage
A roofline job is only as good as where the water goes. We check that downpipes discharge correctly — to a gully, a soakaway, or the surface water drain — and are not simply spilling against the wall, which causes the penetrating damp so common on older Perth properties. Re-routing a downpipe to discharge properly is a small addition during a roofline job that prevents a recurring damp problem, and we flag it at survey rather than fitting new guttering to a bad drainage arrangement.
The Bargeboard Detail
The bargeboard — the sloping board at the gable end — is the part of the roofline most exposed to weather and the first to rot on Perth's estate housing. It is also the part cheap roofline jobs most often skip, capping the flat fascia but leaving the failing bargeboard. A proper roofline replacement includes the bargeboards, and we itemise them so you can see they are covered rather than discovering later that the worst-exposed timber was left untouched.
