Pasadena Texas hit by storms 713 789-6400 Storms are coming, its that time of year, be ready! Have a roofing repair company on hand, get to know them before you need a company and can't find one. How much does a new roof cost to be installed? "10 or 20" years ago? How long has it been, you may have a big surprise to find out the cost! materials and labor have increased dramatically. It costing as much as a new car, you may need to put it your budget so to save money for this expense. To buy time we suggest an preventive maintenance inspection every 2 to 4 years, dealing with the cost of a repair opposed of a replacement, and generally our repairs out last the existing roof.. It depends any where from $280.00 to $350.00 per square, a square is 10' x 10' = 100' is called one square.
