The Danger of Conservatory Clad Over Roofs

Clad Over Roofs

Just because a tiled roof looks professional, it doesn’t mean that it is!

The popularity of the conservatory is well and truly on the rise, thanks in no small part to new, lightweight tiled conservatory roofs. The most common reason homeowners want to upgrade their worn-out glass or plastic conservatory roof for a high quality tiled replacement is because of the extreme changes in temperatures during summer and winter.

New sophisticated designs and better materials mean that conservatories are now able to retain warmth in the winter months and keep your conservatory cool on sunny days, meaning homeowners now have a space that is usable all year round.

One such revolutionary design is our SupaLite lightweight tiled roof system. We have seen increasing demand in the tiled roof system in the past 12 months as a quality retro-fit product to replace tired conservatory roofs or a high-performance solution for exciting new-build projects.

But this new-found popularity has come at a cost – the number of clad over roofs is on the rise and proving a problem for both the industry and homeowners.

Clad over roofs are when an installer tries to pass off basic timber installation material, low-grade tiles and plasterboard for a real tiled roof to the detriment of the conservatory and the homeowner.

We find it very distressing when we hear of installers practising clad over roofs due to the problems they create for homeowners. It’s important that homeowners are aware of the dangers so that they can enjoy the genuine article instead of a poor imitation.

Rather than replacing the whole conservatory roof, the installer will just take out the old polycarbonate sheets, direct fix timber battens to the pre-existing roof and plaster over to mask any potential issues. This creates a number of problems. Firstly, the new roof will add too much weight to the original PVCu or aluminium structure that carried the polycarbonate or glass roof, it will offer no measurable insulation or structural calculations and it will be susceptible to cracking plaster and leaking at the first sign of rain.

Considering that it is now a solid tiled roof, the conservatory will now fall under Building Regulations, potentially causing the homeowner issues later down the line when they try to sell their property. The only benefit to the consumer for a clad over is the cost but, while it might feel like the bargain of the century, when you consider the inevitable problems it will cost you a lot more over time. While homeowners have become the direct victims of clad overroofs, installers are at risk of feeling the impact too.

Conservatories are not renowned for being robust but our SupaLite conservatory and orangery system has resolved this problem with the help of aluminium. With this material, the main structure of the system strikes an important balance between sturdiness and lightness: a SupaLite roof is not much heavier than a standard glass roof, but aluminium’s inherent strength also means that they are perfectly suited to coping with the UK’s unpredictable weather. The SupaLite Extralight tiles are also tested by the British Research Establishment to ensure that they are secure and weatherproof.

As the only authorised and approved manufacturer and installer of the SupaLite roof system in East Anglia, we can combat unaffiliated installers who do dodgy clad over roofs, so that consumers can be certain the work carried out is of the highest standard.

In order to save our Customers this time and expense, we have partnered with JHAi – a organisation approved by the Construction Industry Council (CIC) to carry out Building Regulations approvals as an alternative to Local Authorities. This also allows homeowners to avoid any potential issues when it comes to selling their house in the future.

Our SupaLite tiles are also tested by the British Research Establishment to ensure that they are both secure and weatherproof.
