The pointing on the ridges and coping stones had come loose allowing water to ingress into the property. Especially around the velux window. To solve the problem we stripped the slates out around the velux, adding a premium breathable membrane around the perimeter. Diverting any further water penetration around the window. To prevent water getting into the felt we repointed the copings,ridges and replaces any damaged slates.
