Some rooms never seem to get enough light, especially hallways, bathrooms or smaller spaces in the middle of the house. A sun tunnel brings daylight in through the roof using a reflective tube, brightening the room without needing a full skylight.
We install new units, replace worn or faded ones and check the roof around the tunnel to make sure everything stays sealed. All work is done to current BCP requirements for roofing and penetrations.

Sun tunnels are handy for tight spaces where a standard skylight won’t fit. The tube brings in a surprising amount of daylight and doesn’t add heat to the room. They suit metal and tiled roofs, and the installation usually doesn’t need major changes inside your ceiling.
If you’re unsure what size or style works best, we can take a look at your roof and talk you through the options.
We start by checking the roof position and the best spot inside the room for the light to land. After marking out the area, we fit the roof dome, run the reflective tunnel down to the ceiling and place the diffuser neatly. We take our time so everything lines up the way it should.
Once it’s in, we make sure each piece sits properly so the tunnel stays bright and the roof stays sealed. Before we pack up, we double-check the flashing and nearby roof seals to make sure there won’t be any problems during a heavy downpour.
Sun tunnels don’t last forever. Over the years the dome or the tunnel inside can fade, crack or get cloudy, which slows down the amount of light coming through. When that happens, we take a look at the damaged parts and replace whatever is causing the problem, whether it’s the dome, tube or the diffuser inside.
If the flashing or seals around the tunnel have started to wear out, we sort those out at the same time. Once everything is fitted, we check the roof and the ceiling area to make sure the light spreads properly and the room brightens up the way it should.
