Their 50 year warranty on material and labor got me interested in Mammoth. But their professionalism and customer service is why they get my 5 Star Review. It's tough to know after a hail storm who to trust or where to turn. Mammoth is all about intergrity, and they really mean what they say when they tell you "Mammoth Has You Covered!" I very much recommend Mammoth if you need your roof or gutters replaced.
