Are Conservatory Roofs Lightweight?

Traditionally, polycarbonate roofing was the default option for numerous conservatories; this is largely because pre-2010 building regulations dictated that a conservatory roof should be at least 75% translucent. 

In recent years, solid conservatory roofs have grown in popularity due to the durability and energy efficiency they provide, but this style of roofing is not as lightweight as a polycarbonate roof. 

However, does lightweight mean better? Or are there some advantages to opting for a heavier, more substantial conservatory roof? The team here at Nu-Look Conservatory Roof Solutions is here to answer your questions.

Are conservatory roofs lightweight?

If you’re looking to invest in a conservatory roof replacement, chances are you’ll be choosing between three commonly used materials: glass, polycarbonate and solid conservatory roofing. But are these materials lightweight?

• Glass: Appearances can be deceiving and glass conservatory roofing panels are often surprisingly heavy, especially if they are double or triple glazed.

• Polycarbonate: As polycarbonate is a thermoplastic, it is an incredibly lightweight material. Whilst polycarbonate roofing panels are available in different thicknesses that may impact their weight, overall they are much lighter than most other roofing materials.

• Solid: A solid conservatory roof is constructed using a bespoke timber framework and multiple layers of insulation; therefore, it will naturally be heavier than other alternative roofing options. However, here at Nu-Look Conservatory Roof Solutions, we install tiled conservatory roofs that use Metrotile products. These innovative tiles are up to seven times lighter than concrete, clay or slate to offer the best of both worlds to homeowners who prioritise lightweight yet robust roofing.

However, it’s important to remember that lightweight roofing isn’t always the best option; the strength of your chosen roofing material is by far the most important factor. Solid conservatory roofs have a greater load-bearing capacity and provide additional durability and longevity, ensuring your home remains secure and protected for years to come.

Why is a strong conservatory roof important?

Whilst a lightweight conservatory roof is typically cheaper and easier to install, there are a number of other factors that may make you consider a stronger material, including:

Maintenance: Any leaking or damage to your conservatory roof can have disastrous consequences, so it’s important that you can access your roof for maintenance and repair work. Whilst this is relatively simple if you have a solid conservatory roof, polycarbonate roofs are much trickier to access and will likely require specialist equipment, such as long-handled tools, ladders and crawl boards. 

Debris: Falling debris can pose a particular problem if your conservatory has a polycarbonate roof. This lightweight material doesn’t offer the same resilience as a solid roof and any debris could cause cracks, leaks or even break through the roof entirely, especially if the polycarbonate is older and more brittle.

Weather: As we all know, British weather can be unpredictable, so it’s important to ensure that your conservatory roof is made of robust materials that can withstand these conditions. Whilst polycarbonate roofs only have a predicted lifespan of 10 to 20 years, a well-maintained solid conservatory roof is expected to last for 50+ years, making it a far more durable option.

Will my conservatory roof take my weight?*

As one of the leading conservatory roofing experts, we’re often fielding questions from our customers — one of the most common ones being, “Can my conservatory roof take my weight?”.

To put it simply, this all depends on which material your conservatory roof is constructed from, as some have greater load-bearing capacity than others. Polycarbonate is undoubtedly one of the weaker roofing materials and is not designed to support any heavy weight, especially that of a person. Over time, polycarbonate roofing can deteriorate and become brittle, potentially compromising the structural integrity of your conservatory. 

At the opposite end of the spectrum is a solid conservatory roof, which can support your weight and then some. Here at Nu-Look Conservatory Roof Solutions, our solid conservatory roofs are constructed from the most robust materials and are built to withstand various stresses. Before beginning any installation, we’ll always perform a thorough site survey to ensure your existing frame, footings and brickwork can take the weight of your new solid roof.

*You should prioritise your safety when accessing your conservatory roof and always consult an expert like Nu-Look if you’re unsure whether your roof can take your weight.
