BEWARE!! Paid for them to completely seal a commercial roof (nearly $3000) I have had more leaks since their work was done! Had to call them out to fix 3 times in less than 12 months (twice I called for repairs, they took the message but never showed up) The last roof leak I had damaged some computer equipment, I gave them the opportunity to help cover some of the cost since it was clearly poor workmanship that caused the leak... They refused and referred me back to the "fine print in their contract" Based on my experience and the other Yelp reviews I'm surprised these guys are still in business.
