Building Code Information
•Illinois is a 'home rule' state. As such, each community has the ability to
adopt or adopt and amend a model building code. In the Chicagoland Area, there are several building and fire codes that may be adopted by a municipality.
- City of Chicago - The Chicago Building and Fire Codes are used by the city regulating structures within the jursdiction. The code is available for purchase from Index Publishing, at ChicagoCodes.com.
Most of the roofing related items, including the Urban Heat Island Effect Mitigation requirements, Insulation minimum thicknesses, and more are in the Chicago Energy Code. There are some requirements in the Building and Fire Code as well.
Key code points :
- 2009 Chicago Energy Code - Commercial Roofs
Insulation R-VALUE required - Minimun R-20ci
Top surface Reflectivity - Minimum .72 initial OR .50 aged.
Top Surface Reflectivity Exceptions: Vegetative Roofs, Photovoltaics, Concrete Pavers, 15lbs. of Ballast and other materials used to hold the roof membrane in place.
SEE CODE FOR COMPLETE REQUIREMENTS, as it may vary.
Contact a Professional CRCA Roofing Contractor for more info.
- Chicago Suburbs & Illinois - Most of the Chicago Suburbs and the rest of the State of Illinois have adopted versions of the International Code Council's International Building Code, International Residential Code, and International Fire Code, and/or NFPA 101, The Life Safety Code, depending on the jurisdiction.
Verify with each Authority Having Jurisdiction what code is enforced in that community, as it may vary.
Key code points:
Interational Family of Codes
Chapter 15 of the International Building Code covers Roofing issues, while Chapter 16 covers wind uplift, and structural issues pertaning to the roof.
Included in the International Building Code Chapter 15, 'Roof Assemblies and Rooftop Structures' are requirements for
Low and Steep Sloped Roofs and more.
The International Fire Code (2012 version, to be published in late 2011) addresses Vegetative Green Roofs and Photovoltaic Solar Panel requirements when these systems are placed on or integrated into roofs.
The International Energy Conservation Code (IECC) governs the insulation requirements for roofs. Generally in the Chicago Area, the 2009 IECC charts call for an R-20ci insulation on low sloped commercial type roofs. There are allowances for tapered insulation. Consult the IECC code for specific requirements. The International Green Construction Code adds even more R-Value to base code requirements. Watch for completion of this code in Late 2011.
SEE CODE FOR COMPLETE REQUIREMENTS, as it may vary by jurisdication and version of the code.
Key Code Points:
NFPA Codes
NFPA 101, The Life Safety Code, in Chatper 7 and 11 cover means of egress and exit access, plus membrane structures.
NFPA 5000, the Building Construction and Safety Code covers roofing in Chatpers 1, 2, 3 (Definitions), 4, 7, 8 (Insulation-but requirements are in NFPA 900), 11, 13, 15 (Reroofing) and Chapter 34, 35, 38, 45, 48.

CRCA Specifications
•In the early 1970's CRCA worked with the Chicago Chapter CSI to
produce Built-Up Roofing Specifications. With the explosion of the number of roofing systems available today, and master specification programs, CRCA has not researched this area for some time.
CRCA research has found that CSI and CSC's MasterFormat have all roofing related items listed in Division 7. Vegetatve Green Roofs are called 'Vegetated Protected Membrane Roofing - 07-55-63' in Masterformat 2004 and 2010.
