Expert Green Roofs in Launceston, Cornwall

One of the most common questions we get asked while we're out and about in town is: "Do they actually save me money?" The short answer is a resounding yes. Think of a green roof as a thick, natural duvet for your home. During those chilly Cornish winters, the layers of substrate and vegetation provide incredible thermal insulation, keeping the heat inside where it belongs.But what about the summer? Unlike standard black bitumen roofs that soak up the sun and turn your upstairs into an oven, a living roof uses 'urban cooling' to keep things comfortable. It’s a sustainable way to regulate your home’s temperature without constantly reaching for the thermostat. Plus, by shielding your waterproof membranes from harsh UV rays, a green roof can actually double or even triple the lifespan of the structure underneath. It’s a smart investment that pays for itself over time.

Not every roof is the same, which is why we offer two main types of systems tailored to what your building can handle. Most people in Launceston opt for an Extensive Green Roof. These use a shallow soil layer and hardy plants like sedum. They’re lightweight, very low-maintenance, and perfect for sheds, garages, or porches. You basically plant them and let nature do the rest.If you’re looking for something more substantial—perhaps a space you can actually walk on and enjoy—you might be interested in an Intensive Green Roof. Think of this as a rooftop garden. It requires a deeper substrate and a bit more structural support, but it allows for shrubs, grasses, and even small trees. Whether you want a simple 'set and forget' eco-boost or a full-blown sky garden, we've got the expertise to make it happen.

Living at the 'Gateway to Cornwall' means we get our fair share of the wet stuff. When the clouds roll in off Bodmin Moor, your roof needs to be ready. This is where attenuation comes in. Our green roofs act like a giant sponge, soaking up heavy rainfall and releasing it slowly. This reduces the pressure on your gutters and helps prevent local flash flooding—something that's becoming more important for all of us in the South West.We don't just slap some plants on top, either. We use a multi-layered approach including a specialist root barrier to ensure those thirsty plants don't interfere with your roof's integrity. Every material we use is chosen specifically to stand up to our coastal winds and high rainfall, ensuring your roof stays watertight and healthy for decades to come.

Worried that your roof might be too old or too weak? Don't be. Most homeowners we speak to are surprised to learn that many existing flat roofs can be retrofitted with a green system. We start every project with a thorough structural assessment to make sure everything is safe and sound. We’re a local team, operating within a 25-mile radius of Launceston, so we’re never far away if you have questions.From the initial survey to the final planting, we handle the lot.
