Roofing
Renewal of coverings, underlays, gutters and chimney details on leaking, worn roofs — with insulation where needed.

Process
Our technical team measures moisture on site, inspects existing layers and details, takes dimensions and photos.
Based on the survey we prepare a written quote with the system and layer-by-layer materials and labour.
The old covering is removed section by section; open areas are tarped each evening.
Rotten rafters and purlins are replaced and OSB decking fitted.
Underlay, covering, ridge and chimney details are installed; gutters renewed.
At completion we carry out a water test or visual inspection and hand over a photo report and written warranty certificate.
