A good roof starts with the appropriate design and materials selection. To provide a cost effective long term roofing solution, the consultant must look at the building and its contents and function as the beginning of the design process. This will help to determine the type of roof system, and the type of materials & products to be specified.
Building codes, occupancy issues (sensitivity to noise, fumes, dust), building use, climate exposure, substrate type (wood, steel, concrete), slope/drainage, roof traffic, durability, construction access, capital budget and service life requirements all play an important part of the design equation.
Roofing Products
Today a wide selection of roofing products can be installed on your roof. From the traditional built-up (asphalt & gravel) roofs, to polymer modified asphalt roofing membranes, or energy saving single-ply (PVC, TPO, EPDM) roofing systems, and roof coatings. Each of these systems can provide excellent long term roofing performance when installed on the appropriate building. No single type of roofing product will fit the needs of all buildings. Typically CRC will look at several options and refine the final choice of roof system in discussions with the client to fit their building using the above criteria.
Specifications
Good specifications outlining the application of the chosen roofing system communicate the necessary technical requirements during the construction process. These requirements establish a benchmark that can be inspected for compliance and acceptance. A specification package will include the following components.
- Instructions to the Bidders
- Bid Forms
- Contract Agreement
- General Conditions
- Technical Sections
- Roof Plans
- Detail Drawings
