Roof repairs in Southwick
A Southwick wall stain can start at an open roof edge even though the gutter directly below appears to be the cause. Tracing the rainwater route from covering to downpipe avoids replacing sound tiles for a drainage problem.
Roofing and guttering in Southwick, including the roof-edge and drainage faults behind staining on exterior walls.

In Southwick, a stain beneath the gutter may come from an overflowing outlet, a loose joint or water escaping at the roof edge. We trace the rainwater route before deciding which part needs repair.

The same mark can result from a leaking gutter joint, blocked outlet or downpipe fault, each with a different repair. A sound gutter fall and secure fascia matter as much as the covering where water has reached the eaves.

A local replacement may be enough if neighbouring tiles, fixings and underlay remain sound. The reason for the slip should be checked first.
The perimeter flashing, tiles above it or drainage channel beside it may be at fault. The window and surrounding covering should be checked as one junction.
A worn seal may be one cause, but poor support or an incorrect fall can keep stressing the joint. The run and outlet need checking together.
Water can travel before it appears indoors, and nearby fixings or flashings may also be worn. The full affected area should be defined from the roof condition.
