Our Work

Our team has many years experience in all areas of the industry including 2D/3D CAD design and BIM (tbc), estimating, technical engineering including thermal, structural and rainwater calculations.

Our in-house team of estimators and designers will work with clients and contractors to develop an integrated solution to the envelope requirement and where appropriate recommend the most suitable products to ensure a practical and buildable solution.

Working to strict safety and environmental practices, we work closely with other trades to ensure completion to time, budget and most importantly to the highest standards of workmanship.


We offer a range of sustainable building solutions for clients including high performance roofing and cladding systems, photovoltaic roofs and green roofs that offer a number of environmental and aesthetic benefits.

The company is pioneering the drive for sustainability, evidenced by the installation of Vitral atrium glazing at Thorpe Park Leeds, the highest BREEAM rated building in the UK.

Equipped with a talent for achieving sales growth and profitability against substantial competition, in May 2011 Gavin was appointed managing director, succeeding his father, Frank Quinlan upon his retirement.

In his rise to MD, Gavin predominantly concentrated his energies on the manufacturing arm of the business, but also worked as the company contracts coordinator, as well as managing various contracts. With a strong grounding in all aspects of the enterprise, from the shop floor to the boardroom, Gavin is perfectly placed to oversee the day-to-day running of the business, including all procurement. His role in driving the business forward and ensuring clients receive the very best from all departments, at all times, is also key to Gavin’s continuing success.

Outside of the business, Gavin, a type 1 diabetic of 20 years, has run two London Marathons and Trekked to Everest Base Camp raising money “for the cause”. Gavin’s other interests include reading, music and attending the theatre; being a member of the Royal Shakespeare Company.

His strong experience within these two industries proved to be a real asset when he joined Cover Structure. Indeed it was Paul who introduced Vitral Roof Glazing into the company, with which the company has had great success over the past 15 years.

Joining Cover Structure in April 1996 he developed from senior draughtsman, to drawing office manager in 2001. The role within the drawing office saw Paul progress into the estimating department and, in May 2011, he was appointed commercial director at Cover Structure.

Supply Chain

Our supply chain partners are integral to our client, delivery and quality control.

We select our partners carefully from leading manufacturers in the UK, and where appropriate, beyond. We evaluate quality of product and service whilst monitoring environmental and sustainability issues to ensure a green footprint where practicable and adherence to our own environmental standards. We review our partners’ products regularly to ensure that in turn we can offer our clients the most appropriate and technically advanced solutions for their individual projects.
