-
When it comes to commercial roofing, there is no one-size-fits-all solution. Every roof has its own unique challenges and characteristics, such as shape, size, slope, client budget, environmental conditions, and owner needs. It is important to approach each roofing task with a tailored strategy, recognizing the individual requirements and complexities rather than applying a uniform solution. This underscores the importance of choosing a contractor that can deliver a customized roof system that fits your specific needs.
-
Seamless roofs have fewer leaks because they lack joints or seams, which are the most common points of entry for water in traditional roofing systems. When a roof is seamless, like with liquid-applied membranes, it forms a continuous, unbroken surface. This monolithic barrier doesn’t have the gaps or overlaps where water can typically seep through, reducing the likelihood of leaks and water damage and effectively safeguarding the building’s assets.
-
A “No Dollar Limit” (NDL) manufacturer warranty offers comprehensive coverage without a maximum reimbursement limit for material and labor costs for repairing or replacing defective roofing. Manufacturers will only warrant materials and installation they trust, which can give you confidence in the roofing system and installer you’ve chosen. An NDL enhances building value and provides long-term protection, covering 10 to 20 years or more. With its transferability to new owners, this warranty is a wise consideration for any significant roofing investment.
-
Avoiding a full roof tear-off and recoating the old roof instead can save you money, reduce waste, save time, preserve your building integrity, and enhance energy efficiency. We exhaust all other restoration options before resorting to a full roof tear-off. Only when structural integrity is compromised, or extensive damage is beyond repair, a complete tear-off may be necessary.
-
Thanks to their robust, unbroken structure, monolithic seamless roofs are well-suited to withstand the varying demands of different climates. In areas prone to heavy rainfall or snow, the seamless surface provides superior water resistance, ensuring that moisture does not penetrate the building. For buildings in hot or sunny climates, these roofs can be formulated with reflective coatings that help to reduce heat absorption, enhancing indoor comfort and reducing cooling costs.
-
When seeking out a roofing contractor, it’s crucial to look for those with accreditations and certifications that go beyond the basic standards. These accreditations are not just titles or certificates; they represent a commitment to excellence, quality, and continuous improvement in the roofing industry.

They are extremely knowledgeable in all aspects of roofing industry as well as general construction. While I have seen Strong undertake every task with pride and excellence, they undoubtedly excel in Spray Polyurethane Foam (SPF) and coatings. The certifications, equipment and experience they possess is hard to complete with or find.
Strong Contractors helped us troubleshoot and find solutions to several unusual circumstances, including our most recent project, which consisted of initial 120 SQ of EPDM repair and 600 SQ of SPF and silicone coating on the entire roof. This project resulted in 20 NDL from Firestone (GACO) and was completed in 10 working days. The customer was extremely satisfied with the timeline and the finished product. We hope to continue working with Strong Contractors for years to come.
