  • "...an amazing product and so versatile..."

    Following 23 years of successfully installing Glass Roof Conservatories Amazon came across the first edition Guardian roof, this immediately took our interest and we straight away discussed a deal to promote this product. We had felt the Conservatory market was stale and needed an fresh injection. The Guardian Warm Roof certainly did this. We launched the Guardian Warm Roof 9 years ago at the Ideal Home Show and haven’t looked back since. With over 1500 roofs installed in the last 9 years we have found the Guardian Warm Roof an amazing product and so versatile to all shapes and sizes of Conservatories. We promote and install this product as our flagship product and look forward to installing this brand for many more years.
