Designed to last a lifetime

Although our warranties do not currently exceed 40 years, you can rest assured that all of our roofs are designed to last a lifetime.

So you can expect many, many years of good use. Whether your building is new or old, commercial or domestic, choose Topseal for your next roofing project.

If you would like to find out more about our guarantees or have any questions, please contact us directly on 01423 886495.

Insurance Backed Warranty

For total peace of mind, purchase one of our 10 year Insurance Backed Warranties. These are designed to work with your Guarantee Protection Certificate to protect you should Topseal go out of business. Each Insurance Backed Warranty is offered by Home Pro and if you would like to find out more about current premiums, please contact us direct.

Guarantee Protection Certificate

If you wish to protect your guarantee why not take advantage of our Guarantee Protection Scheme. This ensures that your guarantee is protected should the worst happen and an approved installer ceases to trade, which may be due to insolvency, bankruptcy or liquidation of the principles. A Guarantee Protection Certificate is very reasonably priced at £100 for a domestic roof up to the value of £15000 and £200 over the value of £15000 making it excellent value for money.

Should you wish to purchase a Guarantee Protection Certificate for a commercial property, please take note of the costs below.

Commercial roof up to £10,000 = 3% of contract value

Commercial roof over £10,000 = 2.5% of contract value

Local Authority or Housing Association roofs = 1.5% of contract value

Block of Flats = 1.5% of contract value

Guarantee Information

We are so confident with the quality of our GRP roofing systems that we offer 25, 30 and 40 year guarantees, to give you peace of mind that our product is designed to last.

20 year Guarantee

The Topseal Direct Lay system comes with a 20 year product and workmanship guarantee. This system is suitable for refurbishment and new build roofs.

25 & 30 Year Guarantees

The 25 year guarantee comes with each of our standard installations. The 30 year guarantee is available with our HD roofing systems but this does not include walkways, terraces, balconies or areas subject to heavy foot traffic (a 25 year guarantee will be issued for these).

40 Year Guarantee

We’re so confident with the Topseal Doubletop system that we’re offering a 40 year guarantee on each roofing installation. Once installed, you won’t have to worry about your roof leaking, as it’s completely watertight and designed to last.



Every Topseal installer is allocated a unique verification number to prevent 3rd party misrepresentation. You should always ask any Topseal installer for their verification number.
