How to look after a tiled conservatory roof and gutters
A solid tiled roof needs less attention than glass or polycarbonate, but it still needs checking. Find out what to look for on the tiles, flashings, gutters and the plastered ceiling inside your home.
Checking the tiles for damage or movement
Tiled conservatory roofs are built to last, but wind, debris and general weathering can shift things over time. Twice a year, usually in spring and autumn, look at the roof from ground level. You do not need to climb up. A pair of binoculars is enough to spot slipped tiles, cracked edges or patches where moss has taken hold.
If a tile has moved out of line, water can get underneath it. That moisture then sits against the timber battens or the insulation layer below. Left alone, this causes rot or damp inside the structure. A specialist fitter can replace individual tiles without disturbing the rest of the roof, so report anything that looks out of place rather than leaving it until the next heavy rain.
Moss holds moisture against the surface. On a low-pitched conservatory roof, where water drains more slowly than on a steep house roof, moss growth speeds up. Gentle brushing removes it. Pressure washing forces water under the tiles and into the warm roof layers, so avoid it.
Inspecting flashings where the roof meets the wall
The lead or metal strip sealing the gap between the conservatory roof and the house wall does most of the waterproofing work. If it pulls away, lifts or cracks, rain runs straight down the back of the frame and into the room. This is the most common cause of leaks on any extension.
Stand inside the conservatory during heavy rain and look at the join where the ceiling meets the house wall. Any dark patch, drip or tide mark points to a failed flashing. Outside, check whether the sealant along the top edge has dried out or split. Old sealant shrinks and leaves gaps.
Flashings expand and contract with temperature changes. Over several years they fatigue. Replacing a section of lead or resealing the joint is straightforward work for a roofer, but it must happen before water reaches the insulation or the plasterboard beneath. Catching it early keeps the repair small.
Keeping gutters and downpipes clear
Gutters on a conservatory collect leaves, twigs and silt faster than those on a main house because the roof sits lower, closer to surrounding trees. Blocked gutters overflow. The water then runs down the fascias, stains the frames and pools around the base of the extension.
Clear them out at least once in late autumn after the leaves have dropped. Scoop the debris by hand or with a small trowel, then flush the gutter with a hose to confirm water flows freely toward the downpipe. Check the brackets too. Plastic guttering sags when a bracket snaps, creating a dip where water sits permanently.
Downpipes block less often but cause worse problems when they do. If water backs up in the gutter during a storm, run the hose down the pipe from the top to push the obstruction through. Persistent blockages mean roots or soil have entered the underground drainage, which a drainage specialist can clear.
Looking at the plastered ceiling inside
Inside the conservatory, the plastered ceiling hides the insulation and the structural timbers. It also shows you when something above has gone wrong. Hairline cracks along the joints between plasterboards are normal in the first year as materials settle. Wider cracks, bubbling paint or soft spots are not.
A damp patch on the ceiling means water has passed through the tiles or the flashings and reached the board. Plasterboard loses strength when wet, so a sagging area needs attention quickly. Do not paint over a stain without finding where the water came from. The paint will peel again within weeks.
Condensation can also leave marks, though a properly insulated warm roof rarely suffers from it. If you see mist forming on the ceiling in winter, the room may lack ventilation. Opening a window briefly or checking that trickle vents in the windows and doors are unblocked helps moisture escape before it settles on cold surfaces.
When to ask a specialist to take a closer look
Most maintenance involves looking, clearing debris and keeping an eye on small changes. But some signs mean the problem is past a quick fix. Water dripping during rain, a visible sag in the roofline, or large sections of missing pointing between tiles all need a professional assessment.
Specialist conservatory roofers carry the right ladders, safety equipment and knowledge of how these structures differ from standard house roofs. They understand the layers of a warm roof system and know how to remove a tile without damaging the membrane underneath. Attempting repairs yourself risks breaking the waterproof seal or voiding any remaining guarantee.
If you notice a problem but cannot tell how serious it is, describe what you see and send an enquiry. A specialist firm will arrange a visit, inspect the roof thoroughly and explain what needs doing. You receive a clear picture of the condition of your home and a decision based on facts rather than guesswork.
