Leaking Conservatory Causes
There are many possible causes of leaks, some may incorrect or defective parts, poor fitting and lack of maintenance.
Remember also that the source of leaks or damp may not be caused by a problem with the conservatory itself, for example the presence of a previously fitted cavity wall tray could render damp on the inside of the conservatory.
Faulty lead flashing
Lead is often used as the material for 'flashing', to provide cover over the joint between a conservatory and a house. Lead is chosen because it is durable, a great sound-proofer and an insulator. Lead has the ability to expand and contract as the temperature rises and falls and can be 'dressed' into different shapes to suit various applications. Although highly resistant to corrosion, leaks can occur if poorly fitted. Another material often used is 'Flashband' which is an adhesive flashing used to fix a conservatory repair. Often flashband is a temporary measure and while it has its uses is not as permanent as lead flashing.
Lead flashing is usually inserted into the mortar joint between courses of brick, with small pieces of lead often used to wedge the flashing in place until the joint is re-sealed with mortar or a good lead flashing sealant, like Flash-mate. High quality Code 3 lead roll and building regulations approved Code 4 lead roll is available from our sister company. Flashing Tape is also available for DIY repairs.
Loose cappings/slipped roof panels
Over time uPVC cappings can loose their compression against the roof material, which provides rainwater with a route through a conservatory roof. It can also allows the roof material to slide down the glazing bars. A slipped roof panel will create a gap at the ridge of the roof through which water may enter, along with cold drafts and noise. Fix slipped roof panels by sliding the panels back in to place and replacing any missing or loose glazing bar end caps.
To repair slipped panels it is sometimes necessary to add retaining clips to the base of the roof spar to stop the problem re-occuring. If you notice slipped panels resulting from broken or missing end caps, then the most affordable self-help solution may be to purchase either our Ultraframe End Cap Replacement Kit or Universal End Cap Replacement Kit. They are fairly easy to instal and the universal kit is designed to fit the majority of conservatory roof systems.
The uPVC cappings may just need tapping back down onto the aluminium glazing bars, which should be done carefuly with a nylon hammer or by protecting the capping with a length of wood or cloth.
Leaking roof vents
Conservatory roof vents are a wonderful addition to a conservatory. As heat rises they can provide excellent ventilation and the ability to better control the environment within. However, they are not exempt from the occasional problem. To repair a roof vent, it is often necessary to strip it down and thoroughly clean it before re-assembling, which Truly Conservatory Repairs will be glad to help you with.
Drafts and water entering the conservatory through the roof is sometimes caused by perished gaskets and seals. These plastic or rubber conservatory seals can deteriorate with age and through contact with incompatible detergents or corrosive materials. Repairing, or replacing damaged and perished seals can make your conservatory roof water tight once more.
A popular solution for re-sealing wooden conservatory roofs is the Sunwood Timber Glazing System. Sunwood uses a Screw-Down rafter bar and a Snap-Tight rafter bar system with conservatory ridge and eaves components for total roof coverage. A leaking wooden conservatory, that may otherwise be in good order, could be clad in Sunwoods aluminium or PVC-u cappings and have it's usable life extended as a result.
