Ridge Repair in Seascale

The Problem

This detached bungalow sits just 200 metres from the Irish Sea coast at Seascale, enduring some of the most severe wind exposure in West Cumbria. A succession of winter storms had lifted and displaced four ridge tiles from the 12-metre main ridge, and the mortar bedding had cracked and crumbled along its entire length. Several ridge tiles were rocking loosely — a serious hazard given the bungalow's proximity to a public footpath. Rain was driving in through the gaps between the displaced tiles, causing water damage in the loft and bedroom below. The salt-laden coastal air had also accelerated corrosion of the original galvanised steel ridge fixings, contributing to the failures. The homeowner needed both an immediate temporary fix and a permanent solution that could withstand the extreme coastal conditions.

Our Solution

We provided emergency temporary weatherproofing within hours of the call, securing heavy-duty tarpaulins along the ridge. Within a week, we returned with scaffold to carry out permanent repairs. Every ridge tile was carefully lifted and the old crumbling mortar was raked out completely. We installed a modern dry fix ridge system comprising a ventilated ridge roll, stainless steel universal ridge clips at every tile position, and A4 marine-grade stainless steel fixing screws driven through the clips into the ridge board. This system provides mechanical restraint rated to withstand wind speeds exceeding 120mph — well above anything experienced on the Cumbrian coast. Four damaged ridge tiles were replaced with new matching half-round concrete ridges, and the ventilated ridge roll provides continuous roof space ventilation that improves loft conditions.

The Result

The mechanically fixed ridge has now withstood multiple severe coastal storms without any movement whatsoever — a dramatic improvement over the mortar bedding that failed repeatedly. The homeowner no longer worries about ridge tiles falling onto the footpath below, and the water damage in the bedroom has been fully remedied. The stainless steel fixings are completely immune to the salt-air corrosion that destroyed the original galvanised fixings, ensuring decades of maintenance-free performance. We provided a 15-year guarantee on all ridge repair work.

Dry Fix Ridge System

The mechanical dry fix system uses stainless steel universal clips that grip each ridge tile at the base, combined with a screw fixing through the clip into the ridge board. This system is independently tested to withstand wind uplift loads equivalent to 120mph+ wind speeds, far exceeding the mortar bedding it replaced. For coastal properties in Seascale, mechanical fixings are the only reliable option for ridge security.

A4 Marine-Grade Stainless Steel Fixings

Every fixing on this project was specified in A4 (316) marine-grade stainless steel. At just 200 metres from the Irish Sea, the salt-air corrosion rate is extreme — standard galvanised fixings corrode within 5-10 years in this environment. A4 stainless steel provides genuine lifetime corrosion resistance for all roof fixings in coastal locations.

Ventilated Ridge Roll

The ridge roll is a flexible waterproof membrane that conforms to the roof tile profile, sealing the gap between the ridge tile and the roof tiles below while incorporating ventilation slots. This provides continuous roof space ventilation that helps prevent condensation in the loft — particularly important in the damp coastal climate at Seascale.

Half-Round Concrete Ridge Tiles

The four replacement ridge tiles were matched to the existing half-round concrete profile with the same colour and surface finish. Concrete ridge tiles are inherently heavy, providing natural resistance to wind uplift that complements the mechanical fixings.
