Excellence in Over-Roofing Leaky Existing Roofs

MRC Group’s excellence in Over-Roofing or Over-Cladding solutions is based on over 15 years of international experience in designing, supplying, installing and maintaining over-roofing systems for a vast range of building types.

Over-Roofing provides the opportunity to upgrade / refurbish an existing failing or leaky building envelope without having to remove the existing metal or asbestos roof or cladding system.

The Over-Roofing Support System.

The patented AshGrid™ System, with its brackets from 60mm to 300mm long, is installed in the troughs of the existing steel profiled roof sheets or asbestos roof sheeting, with the brackets fixed directly to the underlying steel or timber purlins, thus creating an engineered, structurally defined cavity between the old and new roof coverings.

The loads from the new roof system are passed back to the structure and NOT onto the existing roof sheeting.

Benefits of Over-Roofing / Cladding:

• The commercial, industrial or retail space below the existing roof  continues to operate while works are undertaken.
• Full range of metal concealed fix and pierced fix roof systems available.
• Provides the opportunity to increase the roof pitch.
• Option of increasing the R-Value performance up to 10 (m2.K/W)
• No requirement to strip and dispose of the existing materials.

MRC Group’s installed over-roofing system, is backed with the unrivalled single source ‘Guardian’ System Warranty which covers design, materials, installation & maintenance for the term of the roofing and cladding system.

Applications of Over-Roofing / Cladding Systems:

• Retail Property.
• Commercial Property.
• Industrial Property.
• Educational Property.
