The majority of roofs for residential buildings in metros like Charlotte NC today are waterproofed with membrane roofing systems. These usually consist of BUR or bituminous built-up roofing, PVC or polyvinyl chloride roofing, EPDM (Ethylene Propylene diene terpolymer) as well TPO or thermoplastic olefins. These materials have been used in the roofing industry for more than 2 decades.
Trends in Charlotte roofing predict that, more or less, the same materials will continue to be used in residential, commercial and industrial roofing systems; but some shift may be seen to lower negative impact on the environment. Specifically, new membrane products may be utilized with greater use of TPOs which is not the case today. Additionally, rising environmental concerns are putting pressure on roof manufacturers to reduce the use of chlorinated materials and also bring about a change in the installation procedures through solvent bearing components or heated bitumen. Sustainable or green roofing is another rising trend in roofing seen in American metros.
The trends in Charlotte roofing show that:
- Roofing materials may not change drastically
- Changes will however be seen in membrane formulations, installation practices, special features and accessories used therein.
- Roofs with longer service life will become popular. Additionally, materials used might show increased resistance to wind and fire along with improved energy efficiency
- The lifetime maintenance costs will likely reduce.
These changes will be carried out with the aim of reducing cost, increasing roof performance and reducing negative impact on the environment.
A notable example, these Roofing contractors Charlotte NC are known for their use of tape to bond the seams in EPDM membranes instead of solvent-based liquid adhesive systems. By the beginning of the year 2025, it is predicted that such use of tape bonded systems will far exceed liquid adhesive seams typical of EPDM roofing.
Re-roofing in Charlotte
When a roof reaches the end of its service life, it must either be replaced or it must be covered over by installing a new membrane directly over the existing one. Until now, the former was given priority since removal of the existing materials ensured that no moisture was trapped under the old membrane. However, today, replacement is not the solution and re-covering the existing roof is the better solution. This is mainly due to the increased labor cost in removing existing shingles and also the disposal of removed materials which strains our already overfilled landfills.
Naturally, the option of recovering the existing membrane can only be done by first ensuring there is no moisture trapped. The entrapped moisture must be dissipated through the roof deck into the building space. Trends now show that a great deal of research is being undertaken to develop proper installation guidelines in order to avoid problems generated by the entrapped moisture. Another factor that research indicates is improving the roof’s wind uplift resistance. Design and installation of roofing systems show that the new materials used must have higher resistance to wind uplift.
Roofing contractors Charlotte NC are also focusing on sustainable roofing manufacturing and installation. Some considerations here include:
- Reuse and recycling of roofing materials. Many European countries, namely Switzerland have shown the world that plasticized PVC roofs can be recycled and nearly 25% of membrane roofing is PVC in that country. This trend is being adopted by the United States too.
- Green roofs. Roofs are increasingly being used for planting trees and plants. Roof gardens help increase the amount of oxygen and purify surrounding air. They also keep the building cooler.
- Environmentally-friendly products. Development and application procedures in roofing are pointing to the use of environmentally-friendly products such as the replacement of HCFC or hydrochlorofluorocarbons as well as other toxic volatile organic compounds that are currently used in the adhesives.
On the downside, the need for skilled roofers will continue to increase but the labor pool dedicated to this sector will continue to shrink. Therefore, automated roofing may become the norm. It is evident that roofing research will continue to play an important role in the trends in manufacturing and installation of residential roofs in Charlotte and other metros.
