Sustainability is not essentially a new idea in the roofing field. However, roof coatings and roofing systems are receiving increased recognition and consideration, based on more stringent environmental regulations and building codes, increased environmental concern and basic considerations.
This kind of focus on sustainability is really good for the field and offers opportunities for engineering and maintenance managers to cut costs while implementing environmentally friendly strategies within roof management systems.
Roof coatings have truly become a proven alternative for managers looking to maintain and then economically restore old roofs, while reducing the load on surrounding roofs.
Roof coatings are simply not a best option for everyone who will restore all roofing problems managers have, or effectively extend the life of every roof system. But when designed correctly, applied and then maintained, coatings are the best ticket to maintaining a roof asset and benefiting the bottom line.
With the best roof coatings, workers can easily repair, resurface and restore any type of aged roof to a maintainable condition. They can restore roofs that have actually leaked if the wet insulation rating is low and can recognize, remove and dispose of affected portions prior to resurfacing.
With careful monitoring and timely completion of remedial work, the roof can be a candidate for successful resurfacing projects to further extend the life of the roof. Additionally, reflective coatings can also slow the effects of ultraviolet (UV) rays and heat aging of roofing membranes by plummeting roof temperatures.
Recent estimates indicate that roofing projects can account for up to 40 percent of construction debris entering landfills. When workers resurface the roof at the best time in the roof’s life sequence, it can delay the need for an expensive repair and avoid the need to rip and strip old insulation and roof membrane.
The emissive and reflective properties of the different coatings result in truly reduced roof temperatures as well as daytime energy use needs, and this helps reduce the load on the HVAC system. Also, unconditioned spaces can get the best heat reduction.
Instead of simply replacing an outdated and dated ceiling for artistic purposes, managers can develop the appearance of a ceiling that is noticeable from the ground or other buildings by applying a coating.
The use of carefully selected applications and coating products on these affected parts can really extend the life of the roof system. Without using this sustainable method, spot deterioration can lead to wet lining, leaks, structural deterioration and the need for temporary replacement.
