Proven Guarantees

Proven Guarantees

You might have seen other companies offering guarantees for 30, 40 or even 50 years. But how long have they been offering these guarantees, and what does their guarantee not cover? Polyroof have been issuing comprehensive, straight-forward and fully transparent labour and material guarantees since 1984, which are supported by independent insurance.
