Repp's Roofing & More

I cannot rate this company because they never got back with me.
I have been trying to get in touch with this business for a couple of weeks now and cannot get any response from the business owner I was able to speak with his wife a couple of times she said she would have him call me however I never heard back and the only information I received from her when I did speak to her was there is no warranty and all I wanted to know was who was the manufacturer of the roofing material that was done July and August 2017 for my mortgage company (I just purchased the home 3-15-2018) so what do I do now when I have no information
