What makes us different?

We have heard it time and again, where all too often a building owner is left in a situation where the product manufacturer and installer are in disagreement on who is at fault. Neither is willing to accept responsibility and the building owner foots the bill, well within the system’s guarantee period.

We take away this doubt by accepting the liability for the design, material and quality of installation workmanship by our network of Approved Contractors.

In the unlikely event of a fault, we will rectify your issue, quickly and effectively, without charge.

Frequently Asked Questions

Waterproofing guarantees can often seem complicated.

We’ve taken every step to simplify our policies and answer the most common quesitons.

If you still have any questions please contact your Garland Technical Manager.

How do I apply for a Single-Point Guarantee?

Once your project has been completed on-site and has been signed off by your dedicated Technical Manager, they will personally arrange all paperwork to produce your guarantee certificate.

You will receive your Guarantee certificate via email and a copy will be digitally stored in your RAMP account for future reference.

Does the Single-Point Guarantee cover design liability?

Yes. Garland UK produces bespoke specifications for each and every project, so in the unlikely event of a roof system failure due to improper design, Garland UK will accept full responsibility and rectify the issue immediately.

Does the Single-Point Guarantee cover labour and materials?

Yes. The guarantee includes labour, materials and all associated costs. If the original Approved Contractor who carried out the work is no longer trading, then we will commission another Garland Approved Contractor to carry out the works.

If a complete roof system needs to be replaced, then we will ensure to use a Garland UK waterproofing system of equal or improved performance.

Is the Single-Point Guarantee backed by Garland UK or Garland Industries?

Garland UK is a 100% owned subsidiary of Garland Industries, therefore all liabilities are the responsibility of Garland Industries.

Does the Single-Point Guarantee cover against consequential loss?

Yes. All Garland UK Guarantees, no matter their duration, protect against consequential loss. This includes damage incurred to the building and contents as a result of the failure of products supplied by Garland UK, up to a value of £200,000.

Additionally, financial consequential loss as a result of business interruption is also covered, up to a value of £200,000.

I’ve discovered a problem with my roof, what do I do?

In the unlikely event of a fault, all you need to do is reach out to your dedicated Technical Manager and notify them of the issue. They will handle all processes for you and resolve the problem as quickly as possible.

Our guarantees are issued based on the system being installed by one of our Approved Contractors. Therefore works carried out by a non-approved contractor may void your warranty.
