Repair the fault or replace the roof?
A leaking conservatory does not always need a completely new roof. Slipped panels, worn gaskets, blocked drainage channels and failed flashing at the house wall can produce similar symptoms. An inspection should distinguish a local weatherproofing problem from a roof whose panels, bars or supporting framework are no longer serviceable.
Note when the problem occurs. Rain entering beside the wall during wind suggests a different investigation from droplets forming across the inside on cold mornings. Condensation can persist after replacement if moisture and ventilation are overlooked. Ground-level photographs, the approximate age of the conservatory and any original paperwork help establish the starting point.
Glass, polycarbonate and solid conservatory roofs
Replacement glazing can retain daylight and views of the sky. Its suitability depends on the glazing specification, frame capacity, roof geometry and detailing at the edges. Solar-control glass may reduce summer heat gain, but shading, orientation and ventilation still influence comfort. Avoid treating a glazing upgrade as a guarantee of year-round temperature control.
Polycarbonate is lightweight, although its thermal and acoustic performance varies with the product and installation. An insulated tiled conservatory roof changes both the appearance and loading of the structure. Systems should be assessed as complete assemblies, including insulation, internal lining, junctions and ventilation, rather than as tiles added over an existing roof.
Check the structure and approval route first
Existing window frames and foundations may not have been designed for a heavier replacement. A competent assessment should consider loads, bracing, connections and the condition of the supporting structure. Structural advice may be necessary before a specification can be agreed; apparently sound frames alone do not establish that the whole conservatory is suitable.
In England, replacing a translucent conservatory roof with a solid roof can change the basis on which the conservatory was exempt from Building Regulations. Ask building control about the proposed work before ordering materials. Planning permission is a separate question, particularly for listed buildings, conservation areas or properties with restricted permitted development rights.
Details that affect comfort and weatherproofing
The roof-to-wall abutment needs a durable weathering detail suited to the wall and covering. Gutters and outlets must accommodate the new roof geometry without sending water behind the frames. Internally, insulation continuity, condensation control and suitable ventilation should be considered together, especially where the room connects closely to the house.
Clarify whether the scope includes internal finishes, rooflights, electrical alterations, gutter changes and making good. Safe access should protect the glazing below and allow materials to be handled without standing on fragile panels. If older boards or sheet materials are suspected to contain asbestos, arrange assessment before they are disturbed.
Preparing a useful enquiry
Provide the footprint, roof shape and photographs taken from a safe position, plus details of heating and the doors between the conservatory and house. Explain whether your priority is reducing glare, addressing leaks or changing the room’s use. Ask for confirmation of service availability and an assessment of suitability before assuming a particular replacement system can be installed.
