Checked Official sources below.
What it covers and whether it is required
LRWA membership is voluntary. It does not replace the designer’s specification, a manufacturer’s installer approval or any Building Regulations duty for the project.
Joining requirements and costs
Applicants use the membership category appropriate to their role and supply the evidence requested by LRWA. Confirm the current contractor or manufacturer criteria and any training, quality and insurance requirements instead of treating all categories as equivalent.
Check the current fees with Liquid Roofing and Waterproofing Association before applying. Ask whether the quotation includes application, assessment, renewal and any per-job charges. Use published fees or ask for a written quotation.
What it means for homeowners
Check the member’s category and the proposed roofing system. Ask which manufacturer approves the installer, what substrate preparation is specified and who provides the guarantee. A trade association listing is not itself a system warranty.
How to check a claim
Official member, card or certificate check: Liquid Roofing and Waterproofing Association.
Match the record to the named person or contracting business. Check the current scope, not just a logo on a van or an old certificate. If the public record does not show the detail you need, ask the body to confirm it before appointing the business.
Where the scheme applies
UK specialist roofing sector. Projects elsewhere and product approvals may have separate conditions; confirm the system’s suitability for the location and use.
Common questions
Does LRWA membership automatically approve an installer for every liquid roofing system?

How do I check Liquid Roofing and Waterproofing Association status?
Use the official verification service linked in this guide. Match the person or legal business name, current status and relevant work category. For a guarantee, check the document issued for your contract as well.
