After several years of roof leaks and remedial repairs, Weld County Buildings and Grounds determined it was time to re-roof the Weld County Courthouse and protect the historic landmark.
The process began in January 2006. Front Range Roofing Systems, LLC was requested to investigate this project for a potential re-roof. After visual inspection, it was determined that this project was a perfect candidate for a Carlisle 60 mil Fleeceback EPDM system, to be installed in low rise adhesive. The existing construction was a silver coated 3-ply smooth built-up roof with perlite insulation over a Pyrobar gypsum panel deck set in steel C-channels. Due to the composition of this deck, mechanical type fasteners could not be utilized to install a new roof system. In addition, the existing slope of the roof was 6:12, further limiting the alternatives for a new roof installation.
With the help of Mr. Greg Ham, of Coastal Specified Products, a re-roof specification was developed to install the Fleeceback roof system. The tenacious adhesive characteristics of the Fast-100 were included in the specification to contend with the slope of the structure as well as eliminating the need to mechanically attach to the existing Pyrobar deck.
In March of 2007, this project was put out to bid and Front Range Roofing Systems, LLC was awarded the project. Due to the high profile nature of this project and the access difficulties, a lot of teamwork and coordination went into the execution of this project. The structure is a heavily used public building with public parking all around as well as an underground parking facility right next to the courthouse. Due to these facts, there was only one location suitable for stocking this project. Stocking for this project included blocking part of the street and rerouting local traffic. Despite the extra expenses associated, this process was done very early in the morning to minimize the impact to the public. This coordination included Weld County to handle traffic control, Sterling Crane to provide the crane and Allied Building Products to handle material delivery. All necessary equipment and materials were loaded onto this project and all parties were gone from the area before vehicle and pedestrian traffic posed additional problems.
The re-roof process began with silver coating of the high walls prior to installing the Fleeceback membrane. The Fleeceback membrane was installed with a bead application of Fast-100 to eliminate overspray potential associated with the adhesive in a full spray application. Upon completion of the Fleeceback membrane, D&D Monarch Sheet Metal was employed to install the counterflashing to complete the project
Again at the conclusion of the project, similar early morning coordination was required for removal of excess materials and equipment from this project. No disruption was caused to the tenants of this building and several area merchants were not aware there was a project of this size was taking place.
Without the cooperation and coordination of all those involved, preserving this historic landmark with minimal public impact, would have been very difficult.
This project was completed on time and within budget for the building owner. A 15 year NDL warranty was provided by Carlisle Syntec. Front Range Roofing Systems, LLC is proud to have been the contractor to perform the challenging roof installation on this historic building.
