A roof is a big investment for the property owner. As with any big investment, knowing in advance what the warranty covers could save the property owner thousands of pounds in the event that a problem arises.

ONE WARRANTY is unique as it provides a single warranty for all of the key elements of the roof, providing the property owner peace of mind, along with a very simple and easy to understand process. For the contractor they can enjoy; easy and free registration, one stop warranty for all items in ONE Warranty, time saved in chasing multiple suppliers or adding warranties with multiple suppliers, reassurance for the home owner that the roofing products are backed by a comprehensive product warranty.
