About us

Rooted in Family, Loyalty, and Innovation

Founded in 1997 by Keith and Sue Ellis, TGM has grown into a second-generation, family-operated business that prioritises safety, quality, and service. Keith and Sue created and developed TGM into a national specialist in the mid to late 90s. As pioneers in integrating iPad technology into roofing in the UK, we’ve maintained enduring national contracts and established ourselves as the premier specialist partner for working at height. Now under the leadership of a new husband-and-wife team, Samantha & Clark Williams, we continue to be passionate and dedicated to serving our clients across the nation.

With 24/7 support and advanced surveying capabilities, we are your trusted partner for working at height on a national scale.
