Commercial Roofing / Cladding and Specialist Works

PROJECT OVERVIEW

Paul and Marie approached CRE after being dissatisfied with previous cladding work on their garage. They tasked CRE with designing, supplying, and fitting the "outer shell" of their new home, specifying 3-inch black plastisol-coated sinusoidal sheeting.

CHALLENGES

The project involved constructing the house with a blockwork buildup, counter-battened with two layers of 47x50mm timber, and insulated with PIR board between the battens to form a vapor control layer (VCL). The roof construction utilized traditional timber trusses, overlaid with a breather membrane and counter-battened with 47x50mm treated timber purlins. A technical challenge was presented by the "up and over" windows on the front of the roof.

SOLUTIONS IMPLEMENTED

CRE supplied full-length roof sheets from ridge to eave, eliminating mid-lap corrosion and extending the roof's lifespan. The front and back walls were also clad with full sheets, precisely cut around window and door apertures, and complemented with bespoke drip, jamb, and cill flashings matching the sheeting. Gable ends featured a mid-lap at eave height due to the roof's overall height. Roof-to-wall details were finished with bespoke barge and fascia flashings, incorporating Lindab powder-coated rainwater goods. For the "up and over" windows, CRE utilized one-piece welded aluminum soakers to divert water runoff into the gutters. Additionally, they assisted in weathering the solar panel penetrations and fitting and sealing extractor fan vents.

OUTCOMES

The project was completed within 16 days and within budget, resulting in a high-quality, aesthetically pleasing, and durable outer shell for the new home.
