Expert Green Roofs in Callington, Cornwall

It's no secret that the weather here in Cornwall can be a bit unpredictable. We get plenty of rain, and that's actually where a green roof shines brightest. Think of it as a giant, natural sponge. Through a process called attenuation, the plants and substrate soak up the heavy downpours we often see rolling in from the coast, slowing down the runoff and taking the massive pressure off your gutters. Beyond the drainage, there's the insulation factor. Most homeowners we chat with are stunned at how much quieter and warmer their homes feel once that layer of greenery is installed. It keeps the heat in during those damp winters and provides a natural cooling effect when the sun finally decides to show its face, helping you save a bit on those rising energy bills.

Not all living roofs are created equal, and choosing the right one depends on what you want to achieve. Most of our Callington customers opt for an Extensive Green Roof. These are lightweight systems using Sedum—hardy, succulent plants that can handle the Cornish wind and rain without needing a professional gardener to look after them. If you're looking for something more substantial, like a space you can actually walk on or use for seating, an Intensive Green Roof might be the answer. These are essentially elevated gardens with deeper substrate (the special growing medium we use) that can support shrubs or even small trees. We also design Biodiverse or Brown Roofs, which are specifically built to mimic the natural Cornish landscape, providing a perfect sanctuary for local bees, butterflies, and birds.

You might be wondering if your roof can actually hold the weight of all those plants. It’s a valid concern, and it’s exactly why we always start with a proper structural survey. We don't just throw some soil on top and hope for the best. Our team installs a high-performance waterproof membrane followed by a specialist root barrier to ensure those thirsty plants don't compromise your home’s structure. We’ve spent years perfecting the balance of drainage layers and filters so that your roof stays watertight while the garden on top flourishes. Because these layers protect the underlying materials from UV damage and temperature swings, a well-installed green roof can actually last twice as long as a standard flat roof. It’s a bit of an investment up front, but the longevity and protection it offers are second to none.
