“Cracked mortar along ridge and hip lines are a common sight on South African roofs, not to mention the unsightly repair work,” says Willem Grové from Coverland.
As an innovative alternative to traditional ridge and hip line applications, the Coverland Dry Ridge System is a waterproof, dry-fix roofing solution involves an easy roll and clip installation on the ridge and hip line of the roof. It allows for optimum air circulation and maximum protection against the elements. “No more messy mortar that cracks and leaks,” emphasises Grové.
How to get neat ridge & hip lines
The system consists of a Coverland Compact Roll, Ridge Trees, Kro clips and ridge clips.
“The key to the efficacy of the Dry Ridge System is the Coverland Compact Roll. Thanks to its unique, breathable composition, it ensures the circulation of fresh air inside the roof, thereby preventing damp and mould,” explains Grové.
The unique 4-Layer Assembly® of the Compact Roll ensures:
• Sustainable sealing (butyl-supported aluminium compound).
• High tearing strength (very resistant PET Polyisobutylene compound).
• Maximum waterproofing properties (ventilating holes are covered by a high-performance fleece).
• Extreme adhesion, due to the highly effective CH-bond butyl glue.
“The Compact Roll can be stretched to fit most roof tile profiles and its unique, integrated waterproofing and ventilation features, when combined with the Ridge Tree, provide optimum airflow and a 100% leak-free performance,” Grové adds.
Ridge Trees allows an optimal alignment of the ridge and hip battens. Attached under the topmost batten and onto the counter batten or rafter, the ridge and hip tree is used to fix the ridge runner. The steel is strong yet pliable, while the holes allow for easy fixing to the ridge batten using screws.
Made from corrosion-resistant stainless spring steel, the Kro clips fix cut tiles to the hip structure without the need for drilling into the concrete tile. Supplied with a 30cm long corrosion-resistant binding wire, which is fixed from the clip to the nail in the support batten (hip batten or hip rafter), it is easy to install. Only nails and a hammer are required.
The ridge clips are made from stove-enamelled aluminium and are used to fasten ridge tiles to the ridge and hip batten once the Compact Roll has been applied.
“Although more expensive than traditional mortar fixing, the Coverland Dry Ridge system is a long term solution that is easy to install, aesthetically pleasing and best of all, maintenance free,” Grové concludes.
