AN AREA AT RISK
Valleys, on roof, are critical areas. Being located at the junction of two roofs, it is vulnerable to the water flows of two different roofs. An insurance company survey about roof leakages revealed that 30% of roof leakages originated from the valley areas. Hence, it is very important to treat this area carefully with the right products and methods.
