Roof Of The Month
An Islandia Long Island based Pharmaceutical manufacturer needed a new roof but could not afford the downtime that a conventional removal and replacement would take, not to mention the budget breaking cost. They learned of our non-disruptive, money saving coating solution and we prevented another 50 tons of ripped of petroleum laden roof from making its way to a landfill!

Now the roof doesnt leak, the cool roof lowered their air conditioning cost and, they have money for a summer party!

we stop leaks so barbecues can happen!
