Maintenance & Aftercare
A conservatory in Glasgow's wet, mild climate needs a specific maintenance routine to stop moss, seal failure and frame wear building up unnoticed.
A conservatory roof should be checked at least once a year in Glasgow, because the combination of rainfall and low winter sun accelerates moss growth and seal wear compared with drier parts of the UK.
Check the roof after autumn leaf-fall and again after the worst of winter. Moss and debris in valley gutters is the most common cause of an internal leak that gets blamed on the roof itself.
A warm roof needs an annual gutter and flashing check, but no more than that, because there is no glazing seal or polycarbonate sheet to fail.
This is one of the practical, ongoing advantages of a warm roof beyond the thermal performance — it removes the recurring glazing-seal and sheet-discolouration maintenance that glass and polycarbonate roofs need.
Wash uPVC and aluminium frames twice a year with warm water and mild detergent, and lubricate hinges and locks annually to stop them seizing.
Condensation left unmanaged causes mould on frames, sills and soft furnishings, and background ventilation combined with steady heating is the long-term fix.
See our full guide to conservatory condensation and ventilation for the causes and fixes in detail.
A conservatory needs more than routine maintenance when frames feel draughty, glazing units show internal misting, or the roof allows visible daylight through joints — all signs the structure has moved past general upkeep.
At that point a survey is worth having before spending on repairs, since it is sometimes more cost-effective to replace the roof than to keep patching an ageing one.
