We've been costumers of Cool Foam for a number of years. We had our first roof coat with them in 2014, with a 5 year guarantee, then another coat again in 2019 but in between we had a different kind of roof, an addition to the house, that we didn't include before because it was in fair condition but when a monsoon gave us a terrible leak we called them and they came and fix it in no time, they coated the whole thing, and it was very affordable considering they have to make the whole move for a small part of the roof. We recommend Bill and his guys, they are proffesionals, they if possible take you to the roof so you can take a look at their job, very happy with them, and will continue to call them as long as is needed. read more
