Standing seam and twin skin metal roofing and cladding technical services

About us

Norfolk based DHLowe Ltd provides back up engineering support to manufacturers and installers in relation to metal roofing and cladding systems, particularly standing seam systems, throughout the UK.  

Roofing and cladding subcontractor or manufacturer? DHLowe Ltd can be your back up technical resource - to provide technical support, technical writing, design reviews, structural engineering calculations, feedback and construction details review.......etc.

It is unfortunately common for a standing seam or twin skin metal roof or wall system to be selected and specified by the architect to suit aesthetics and form, the primary structure is designed to suit the purlins and economy, the roofer installs what is specified, and unwittingly, the structural capacity of the envelope is not checked. Sometimes this only becomes evident after storm damage.   Metal roofing and cladding needs to be subject to structural design checks. DHLowe Ltd can provide this service to you.

DHLowe Ltd is a member of the MCRMA (Metal Cladding and Roofing Manufacturer’s Association): Industry Support Services Group
