The Chadwell Group, LP has completed well over 3,000 projects on some of the most difficult roofing and waterproofing renovation projects in the country, since being founded in 1983. The Chadwell Group, LP has a long track record of solving complicated roofing and waterproofing problems and implementing solutions to those problems, as well as consulting on both large and small new construction projects. Below are a few examples of our projects.
The Chadwell Group, LP performed evaluation and testing services involving a major wind loss on the 4 buildings in this complex. The building experienced straight line winds that lifted the roof system off of the deck and caused a catastrophic failure. We provided design, inspection, and testing services in the replacement of the roofs on this large prestigious complex in North Dallas.
The Chadwell Group, LP performed investigation, design, and construction administration for the roofs on 6 buildings, comprising 449,500 square feet. The 6 buildings were split into 3 packages with different contractors. Some of these buildings had “critical” contents that could be damaged by something as small as dust; therefore interior protection was a major factor on all buildings. New roofing systems ranged from retrofits with a 60 mil fully-adhered TPO to replacement with multi-ply modified bitumen roofs.
The Chadwell Group, LP performed the roof design, inspection, and testing for the roof system for HOK Architects. This is one of the largest slate roofs in the United States. The biggest obstacle in design was to provide proper expansion and contraction for the slate. The proper design of the attachment of the Welch slate to the deck was critical.
The Chadwell Group, LP performed design, bidding/negotiation, and construction administration services for the roof replacement of the Technology Office Building. A limited budget, energy savings goals, and inadequate overflow systems drove the solutions for this project. We were able to reduce costs by leaving the existing roofing in place while still obtaining a 20 year NDL warranty. All of the work had to be constructed while maintaining the operation of the 210,000 square foot facility.
The Chadwell Group, LP was awarded a 5-year Indefinite Delivery contract for roofing and waterproofing consulting with the DFW Airport Board. The airport covers 26.9 square miles with 17,207 acres of real property. We performed a Biannual Survey and Update of the 5-Year Roofing and Waterproofing Plan on 813 roof areas and all walls of the buildings. We have provided design, bidding/negotiation, construction administration, and quality control services on 25 buildings at the airport.
Terminal D is a 2,000,000 sq ft facility capable of handling 32,000 passengers daily. The Chadwell Group, LP performed consulting services related to the design and construction of this extremely complex metal roof for Austin Commercial who served as the CM at Risk. The solution utilized elements of roofing, waterproofing, and curtain-wall design. We also had to coordinate with 3 architectural firms during the process.
The Chadwell Group, LP performed emergency evaluation services, design, and inspections on these roofs. They sustained significant damage in August 2005 from Hurricane Katrina. Being the tallest building in Louisiana at just less than 700 feet and its location on the coast in a hurricane prone region subjects the roof to significant wind uplift pressures. The roof design had to sustain the wind uplift pressures while maintaining a “zero” edge metal profile at the perimeter of the roofs.
The Chadwell Group, LP performed evaluation and testing services involving significant design and construction problems involving the structure and waterproofing of the parking garage. We then performed consulting and inspection services related to the repair of the structure and the replacement of the waterproofing system.

The Chadwell Group, LP performed a Plan and Specification Review (Peer Review) of the roof design for this new construction project for the building contractor in order to address roofing-related issues prior to construction. The Chadwell Group, LP provided technical support to the contractors during construction in order to resolve other issues as they developed. Field observations were provided to ensure that the installation of the roofing system met the project requirements.
The Chadwell Group, LP performed extensive wind uplift and moisture testing services on the roof system and evaluated the structural capacity after the building sustained significant tornado damage. We provided design, bidding, and construction administration services for the replacement of the roofs and reattachment of the structure during on-going postal operations.
The Chadwell Group, LP performed investigation, design, bidding/negotiation, and construction administration for the reroofing of this school. This project included the retrofit of 200,000 sq. ft. of roofing. The 25 year-old roofs were trapezoidal metal panels installed over open purlins which had been leaking for the last 15 years. Our design included installing insulation between the existing panel ribs to meet energy codes and installing a fully adhered fleece-back 80 mil PVC roof system with ribs.
The Chadwell Group, LP performed design, inspection, and testing services on this border station complex which included the main border station and 10 auxiliary buildings. The project included the replacement of complex barrel vault, standing seam metal roofs, built-up roofs, and mechanical penthouses with a long history of performance issues. The $1,785,000 budget was met and there were no change orders on this project.
The Chadwell Group, LP has performed testing, investigation, design, bidding/negotiation, construction administration since 1998 for RISD. The Chadwell Group, LP developed a 5-year plan to manage their roofing assets which included 2,235,963 sq. ft. of roofing. The District uses this plan to define the scope of work for their Bond Programs. We also developed RISD roofing standards for their architect to use on new construction projects. The Chadwell Group, LP has provided services on over 60 schools and/or buildings.
The courthouse was built in 1895 on the bluff of the Trinity River where the original military outpost was located. The Chadwell Group, LP has performed consulting services for the repair and maintenance of this roof for 25 years. We have recently performed consulting and inspection services for the replacement of the copper-clad clock tower on this historic centerpiece of Fort Worth culture.
The Chadwell Group, LP performed the roof design, inspection, and testing for the 12 buildings and more than 2 million square feet of roofing, including the Wide Body Hanger, which is the largest single cantilevered hangar structure of its kind in the world.
The Chadwell Group, LP performed the roof design, inspection, and testing for the roof system for HKS Architects. There were very complex roofing and waterproofing issues involved in this building. One of the critical design issues on this domed roof structure was the membrane type and attachment. There were numerous roof gardens and plaza decks on this project as well.
The Chadwell Group, LP performed the roof design, inspection, and testing for the replacement of the roofs on this building. The rooftop units supported the computerized flight training equipment that had to operate 24/7 during construction. The units were located in a recessed “pit” which had improper drainage. Our solution solved the drainage/roofing issues while providing a better aesthetic solution. We covered these areas with standing seam metal roofs while providing ventilation for the units.
The Chadwell Group, LP performed design, bidding/negotiation, and construction administration for the reroofing of a portion of this popular shopping mall. The project included the replacement of 84,400 sq. ft. of roofing on 11 different roof areas. The mall was built in 1979, and the roofs were designed with limited slope because they had a gravel covered, coal tar pitch roofing system. The system had no provisions for overflow, thus the roofs had never met code requirements for drainage which we corrected.
The Chadwell Group, LP performed evaluation and testing services involving hurricane damage. We worked with the owner, architect, and insurance company in resolving the loss, and performed consulting, inspection, and testing services on the repair and replacement of the roofs further complicated by another hurricane during the installation of the roof.
The Modern is a 53,000 sq ft facility designed by Gold Medal award winning architect, Tadao Ando. It is recognized for its stunning water features, reflecting pools, and cantilevered roof. The Chadwell Group, LP performed consulting services for KHA related to the design and construction of the roof system. The roof line is one of the important design elements of this building. One of our main challenges was to design the edge detail to meet the aesthetic goals while maintaining waterproofing integrity.
The Chadwell Group, LP performed the design of a complicated, high-performance roofing system for Building 6 of this complex (65,000 sq. ft.). Code-related issues were addressed such as wind uplift, R-Value requirements, drainage capacity, and the overflow system. Through a series of value engineering efforts with the roofing contractor, we were able to reduce project cost to meet the limited budget while maintaining the quality level and warranty requirements.
