Problem: How to Repair Roof Leaks From Ponding Water, Weather Damage or Short-Lived Repair Materials
A leaking roof can result from improper installation, ponding water, storm damage, roof penetrations and lack of maintenance. Even small roof leaks can create structural problems as well as health and safety hazards. Furthermore, roof leaks can damage equipment and electrical systems within the structure.
Finding the source of a roof leak can be challenging, as can finding a long-lasting repair. Industrial flat roofs with complex shapes, skylights and multiple protrusions make for difficult fixes. The conventional sealants and tapes used to patch such roofs typically deteriorate within a few years, becoming brittle and cracked. As a consequence, leaks reappear and the patch process repeats itself, costing the owner time and money.
Wear caused by daily expansion and contraction movement of dissimilar materials also cause roof leaks. Materials such as metal flashings or brick parapets expand and contract at different rates than the roof substrate and eventually weaken to form cracks where water can seep. This case highlights the need for repair sealants with high bonding strength.
The failure of joints between sheets of rubber or bituminous roofing materials causes problems for flat industrial roofs. Over time, constant freeze/thaw cycles, wind and UV radiation can diminish the joints, causing the formation of gaps and lips where water can enter. Such damage is repairable if discovered early, however, severely neglected roof systems likely lead to replacement.
Solution: Seamless Belzona Polymeric Flat Roof Coatings & Roof Leak Repairs Provide Long-Term Waterproofing
Banks Industrial Group uses Belzona polymeric flat roof coatings and sealant materials to provide and effective and long-term repair for industrial flat roof leaks. With a typical service life of 20+ years, Belzona roof leak repairs and flat roof coatings provide an excellent alternative to short-lived, traditional roof repair methods.
Belzona 3111 Flexible Membrane forms a seamless, elastomeric barrier that is weatherproof and waterproof. It is highly resistant to UV light and will remain flexible in service for a long time. This flexibility allows it to move sympathetically with roof expansion/contraction, avoiding the splits and tears that cause leaking. In addition, the microporous and breathable coating permits moisture trapped underneath to escape while sealing out external rain and weather. Finally, these capabilities combine to ensure a long service life for trouble-free roof sealing.
Liquid applied Belzona coatings conform to complex roof shapes and quickly seals protrusions such as pipes and vents. Furthermore, Belzona roof coatings will tenaciously bond to most substrates including concrete, brick, copper, lead, cast iron, galvanized steel, asphalt, and stone. Consequently, this bonding capability between dissimilar materials provides significant durability and protection against the development of future leaks.
Belzona is easy to apply, easy to maintain, and safe to use. Our flat roof coatings do not require hot work and are solvent-free without harmful VOCs or odors during application.
Emergency Roof Leak Repairs
Fast-curing Belzona 3121 (MR7) allows emergency roof leak repairs in adverse weather conditions including cold temperature down to 32°F as well as wet conditions.
