Why Replace Your Conservatory Roof?

Let's face it, older traditional conservatory roofs are not fit for purpose anymore. For most conservatory owners it's the same issue, they'll use the conservatory but it's either too hot, too cold, or too noisy. Most of the issues are down to one element, the roof. So, if you let our Guardian roof experts in Scotland near it then by replacing the glass or polycarbonate roof with a stylish Guardian™ tiled roof you don't just improve the appearance, you now have a fully insulated soundproofed roof that is exactly the point of having a conservatory in the first place. Not only, can you now use it to its full capabilities, but you are adding extra value to your home as you now have a useable and much more solid structure than before.

All our Guardian roofs come with a comprehensive 10-year insurance backed guarantee and our systems are LABSS approved giving you total peace of mind.

You can be sure that you are in good hands too with BJC Joinery as we only provide you with cost-effective fit for purpose products that meet current energy efficiency regulations. We will advise you carefully on the products most suitable for your requirements, making sure that they fit the look and feel you are after in your home, match up to all the very best standards in energy efficiency and give you the ultimate value for money for your project and it's future worth and usage.
