Meet Mark

With a lifelong passion for construction, Roof Windows Specialist proprietor, Mark O’Neill, developed his skills in the trade from an early age, initially via his father’s contracting business. Mark was roofing houses when he was just 15 years old, and was keen to pursue a career in the industry.

Completing a BTEC in Construction, followed by a degree in the same, Mark went on to work for a local construction company for three years, before working for the world’s biggest roof window manufacturer, VELUX®, which ultimately inspired him to strike out on his own to solve VELUX® customers’ concerns once their 10 year guarantee expired.
