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.

The key elements of a flat or pitched roof are included in ONE WARRANTY. Coverings such as SIGA Natural Slate, FIX R Torch on Felts and SIGnature Clay Roof Tiles are included – to name just a few. The qualifying products can be found here. If you are installing a pitched roof, you must install at least one product from each mandatory product group – batten, breather & covering tile to qualify for a warranty.

All products included in ONE WARRANTY are manufactured to comply with British Standards and European Standards where applicable.

Yes, ONE WARRANTY is specific to the property. If the property is sold the warranty can be transfered to the new owner upon written request.

Participating products must be used throughout the whole roof for those listed as Mandatory. Failure to do so will invalidate the warranty.

Certainly. ONE WARRANTY covers the whole roof, however if a product included has a manufacturer’s warranty for an extended period that you want to take advantage of – you must then apply through the manufacturer’s existing process. For example with SIGA Natural Slate, if you want the full SIGA Natural Slate warranty (between 30 and 75 years), then you must apply for it through the supplying branch as per the existing SIGA Natural Slate warranty process.
