slate roofer and box gutter repair recommendation

Hello Neighbors, I need to have the box gutters repaired on my house and in order to put a new liner in the gutter some slate roofing pieces will need to come down and be reattached. I am looking for a recommendation for a roofer/gutter repair and someone who specifically works on slate. Looking for an individual or company that is reliable and reasonably priced. Please share any good and bad experiences you have encountered. Thanks for your help! Beth Rellis General Manager Park Bruges 412-661-3334
