Who We Are
The Rainwater Guy was founded in 2013 by Jamie Rolph, who initially launched the business as a one-man operation. Jamie’s deep knowledge and hands-on experience have since positioned him as a trusted name in the industry. Today, he leads a growing team of dedicated professionals, but he remains closely involved in day-to-day operations and is often called upon for feasibility site visits, troubleshooting, training, and consultancy work.
Our team is made up of highly qualified specialists committed to ongoing professional development. This ensures we remain at the forefront of our industry, offering customers the latest knowledge, compliant solutions, and expert advice.
