Roof experts and trained inspectors at Kestem can determine the viability of restoring existing roofs. In addition to the condition of the roof, many other factors affect this decision such as age of the roof, estimated replacement cost, cost of restoration, and how much the restoration will extend the life of the roof. Restoration may also include the replacement of a failed roof component such as EPDM seams, or predictive maintenance such as flashings.
Asphaltic coatings are traditionally used to protect the roof and to extend its life. These coatings include alumination (silver coating) and solvent or clay-based coatings. More of today’s coatings are reflective, high albedo coatings or “Cool Roof Coatings,” that not only increase the roof life span but protect from weathering, UV degradation, and reduce energy consumption. Cool roof coatings include Acrylic, silicone, Hypalon, butyl and polyurea.
One of the most common maintenance items on a building is caulking. A building cannot be waterproof or energy-efficient without maintenance of caulked joints. This includes metal to masonry, metal to metal, metal to glass, masonry to masonry as well as joints with wood on one or both sides. Building control joints, expansion joints, surface-mounted counter flashing joints and more need to be checked and maintained regularly.
