We got our flat roof (above garage) repaired this time last year and have an email from the roofer with a 10 year guarantee. Now it's leaking (and causing internal damage) and he's ignoring me, either not turning up or not responding to my texts. I've been very polite but now am planning on emailing him a formal email, my question is do I have a leg to stand on with this 10 year guarantee? What do I do if he doesn't respond?
TIA
