Any building needs an external protection just like a “skin” to avoid its deterioration through the effects of natural elements and weathering. As part of the building envelope, roofs have a decisive role in the durability of the structure as, being the top surface of the building, prevent water penetration through horizontal or slightly inclined surfaces. All these factors make roofs as one of the most critical parts in a structure. 

MasterSeal Roof systems form a fully bonded, seamless waterproofing membrane that avoids welds and seams that are typically the weaker spots in any waterproofing system. MasterSeal Roof systems can be installed on most substrates, including old concrete, built-up felt asphalt and timber substrates.

MasterSeal Roof systems have a clear advantage over conventional waterproofing sheeting especially on roofs with build-ups, penetrations and complicated structures. Also leaking roofs, can be repaired in many cases without removing the old waterproofing layer. This offers clear time and cost savings and reduces the costs for disposal of old membranes.​
