What You Need to Know About Georgia’s Residential Roof Building Codes

Home repairs and renovations are a great way to breathe new life into your home. However, it’s important to remember that certain regulations—namely, Georgia’s building codes—will determine what can and how it should be done. The International Residential Codes (IRC) outlines the standards for roofing work, including new builds and repairs, for single- and two-family homes and townhouses.


Renovations and remodels should always be done by a reputable construction company that is well versed in the IRC’s regulations, especially if you’re doing work on your roof or in your attic. The team at Braswell Construction Group specializes in a wide variety of roofing services, serving residents in Georgia for over 25 years. With our extensive experience in the construction and restoration of commercial and residential roofs, you can be confident your project will meet the requirements outlined by the IRC. Read on to learn more.





Use Approved Roofing Materials


Most roofs in Georgia are made of asphalt shingles or wood shake. The building code requires that the roofing materials be compatible with the building and the other materials used to construct it. The materials must have a manufacturer's identification, an accreditation label, and be recorded on the bill of lading if purchased in bulk.



Maintain the Mandated Roof Structure


The codes require roofs in Georgia to have a 2% or one-quarter inch per 2 inches slope to protect the structure from environmental elements. According to the IRC, roof decks must use approved materials for covering. Coverings must use the approved fasteners, and parapet walls require a non-combustible coping to be installed. The IRC has also established that the thickness of the coping material must be equivalent to that of the parapet wall.



Install Proper Roof Ventilation


Roof ventilation is a standard prerequisite for residential and commercial buildings in Georgia. The dimensions of the roof vent must be between one-sixteenth and one-quarter of an inch. Those that exceed these dimensions should have a wire cloth screen that is corrosion-resistant to shield from elements such as snow and rain.



Follow the Flashing Regulations


The code requires that sheet metal be used for residential roof flashing and counterflashing to ensure that moisture doesn’t penetrate through walls and other openings. The minimum width for valley flashing is 15 inches. Braswell Construction Group will help to protect the permeable sections of your roof by installing the appropriate flashing.



Re-Roofing Requirements


While re-roofing can be an option, the re-roofing codes in Georgia forbid it under certain conditions. If the old roof is waterlogged or has more than one layer of roofing material, then it should be removed. You cannot reroof on a dilapidated roof. For all major roofing repairs, especially re-roofing projects, be sure to hire a professional roofing contractor.
