Background  (PDF Version)

The  Cannon Group is an architectural firm that specializes in roofing, waterproofing and exterior wall projects.  Tremendous changes have occurred over the past twenty-five years in the construction industry, especially in roofing.  Herbert J. Cannon recognized the need for consultants who were dedicated to keeping pace with the almost daily changes in the roofing and waterproofing industry.  The rapid advance of new technology in roofing has resulted in both roofing system improvements and, unfortunately, the failure of many new roofing systems which were supposed to end all of our roofing problems forever.  Our hope and goal with all clients is to develop a long-term relationship which enables the Cannon Group to become familiar with all of our clients facilities, personnel, objectives and problems.  In that way, we can help solve not only immediate “crisis” roofing and exterior building problems, but help to plan and budget for the future in a way that will get the most effective results from available funds.

The Cannon Group is one of the few licensed architectural firms in the country whose sole practice is to provide roofing, waterproofing, and masonry restoration architectural services.  Every one of the projects undertaken by the Cannon Group since it’s’ formation in 1982 has dealt with roof consulting, roof system design, roof installation inspection or exterior building waterproofing.

The Cannon Group has a specialized staff that consists of a unique blend of registered architects, roof consultants, and former roofing contractors and computer professionals.  Our individual staff members bring the firm years of experience obtained from various positions throughout the roofing industry prior to joining our organization.  As licensed architects, the Cannon Group understands all aspects of building construction.  This enables the Cannon Group to analyze and design roofing and waterproofing systems, along with masonry restoration, as they relate to the whole building, not just as an isolated item.  As former contractors, we have in-depth, hands on knowledge of roofing installation procedures, techniques, management, quality control and construction costs.

The Cannon Group has no affiliation with any roofing contractors or roofing material manufacturers.  We can, therefore, keep a completely “open mind” when designing and selecting the most appropriate roofing system to best meet the individual needs of our clients facilities.  Numerous types of roof systems are available for consideration on each roofing project.  For each type of available system there are also numerous different manufacturers of the same type of material.  Our job is to design a roof system, which is the best type for your situation, and to specify only those manufacturers, which produce the best quality materials in their category.  Further, we can provide the necessary construction period services to make sure your new roof system will give you the maximum service life.
