When Rolled Roofing Makes Sense — And Is Code-Compliant in Georgia

If you live in Georgia and are considering rolled roofing (sometimes called mineral-surfaced roll roofing, asphalt roll roofing, or “roll roofing”), there are circumstances under which it meets code and is a reasonable choice. According to the rules adopted via the International Residential Code (IRC) as applied statewide, rolled roofing may be used — especially on low-slope roofs. 

For example:

• Many jurisdictions list rolled roofing as acceptable for low-slope roofs with a pitch as low as 2:12.

• Under certain installation methods (like a “concealed nail method” or a “double-coverage” application), rolled roofing may even be allowed on slopes as low as 1:12 — provided manufacturer instructions are followed carefully.

• When properly installed, rolled roofing must use approved underlayment (often mineral-surfaced roll roofing conforming to specific ASTM standards or acceptable alternates), meet underlayment thickness and fastening rules, and include proper edge/eave overhangs.

Thus, if you have a flat or gently sloped roof section, or a low-pitch roof that doesn’t accommodate standard asphalt shingles or tile, rolled roofing is often a code-permitted, practical — and budget-friendly — solution. It’s especially common for secondary roofs, porches, sheds, detached garages, or low-slope additions.

Code Requirements and Limitations in Georgia

Even when rolled roofing is allowable, you must meet several important code requirements. Some of the key ones are:

• The underlayment must meet standards (for instance, mineral-surfaced roll roofing conforming to ASTM standards) or use an approved underlayment option (including some peel-and-stick underlayments) depending on the roof type and slope. 
• Fastening must be done properly — nails should be placed per manufacturer’s instructions, and nail heads must be flush (not sticking up or penetrating the roofing surface).

• Overhangs (edge and eave) must meet specified dimensions (for example, many local guidelines require 3/8″–½” overhang).

• Flashing, valleys, wall/roof intersections, penetrations (vents, chimneys), and drainage must meet the same waterproofing and moisture-management standards as for other roofing materials.

• If you’re re-roofing (i.e. applying rolled roofing over an existing roof), the code (via the state-adopted IRC provisions) requires that the entire assembly comply with the code — and that previous layers and materials meet allowable conditions.

Another state-wide requirement for roofing in Georgia is installation of a drip edge at eaves and gables (for asphalt-type roofs), per code. 

Finally, the materials themselves must be delivered with proper labeling and certification — i.e. “packaging must have identifying information about the manufacturer and accredited testing agency” (or a certificate for bulk purchases). 

When Rolled Roofing Is Not Your Best Choice (or Not Allowed by Code)

Because rolled roofing is inherently more basic than standard shingles or tiles, there are conditions under which it makes little sense or may be discouraged (or even disallowed) under the building code or by local regulations. Some of those situations include:

• Steep-sloped roofs: Rolled roofing is rarely appropriate for steep roofs, because it doesn’t shed water as reliably as shingles or tile on steep slopes, and code requirements for underlayment, wind resistance, flashing, and drainage are easier to meet with standard shingles or roofing systems.

• High-durability expectations: Compared to asphalt shingles or tile, rolled roofing tends to have shorter lifespan, is more prone to leaks if not extremely well installed, and may perform poorly under heavy Atlanta-area weather (heavy rain, wind, heat, humidity). That makes it a less dependable option for a primary roof.

• Complex roof geometries: Roofs with many penetrations, valleys, dormers, chimneys, or steep transitions often require more robust flashing, venting, and underlayment strategies than rolled roofing can comfortably deliver.

• Fire-safety / insurance concerns: Depending on local fire codes, wildfire risk, and insurance or HOA requirements, more fire-resistant roofing materials (Class A or equivalent) may be preferred. While rolled roofing might meet minimum standards in some cases, shingles, tile, or metal often offer better fire and fire-resistance ratings.

Why Many Georgia Contractors or Roofers Advise Caution — Even When Code Allows It

In practice, many roofers in Georgia treat rolled roofing as a “last-resort” option or a “temporary/secondary roof” rather than first-choice for a primary dwelling roof. Reasons include:

• Durability: Compared to standard asphalt shingles or tile, rolled roofing generally doesn’t last as long, especially under heat and humidity. That means earlier roof replacement, higher long-term maintenance, and more frequent sealant or underlayment rework.

• Moisture & leak risk: Low-slope roofs are easier to seal with roll roofing — but even then, seams, penetrations, flashings, and valleys remain leak-prone areas if not done meticulously.

• Insurance and resale value: Homes with rolled-roof coverings sometimes face higher insurance premiums, or may raise red flags with appraisers or future buyers, especially if roll roofing covers the main roof.

• Code compliance scrutiny: Since rolled roofing installations are more dependent on underlayment, drainage, slope, flashing, and proper nailing, inspectors tend to scrutinize these installations more closely. Any oversight can lead to failed inspection, required remediation, or code violation.

So — When Should You Use Rolled Roofing in Georgia?

You should consider rolled roofing when:

• You have a low-sloped or nearly flat roof section (e.g. 2:12 pitch, or even lower if code-permitted and properly installed).

• The roof is secondary (e.g. porch roof, shed, garage, low-use addition) rather than the main roof of the house.

• Budget or simplicity is a priority, and you understand that rolled roofing may be more of a “function over longevity” solution.

• You or your contractor are willing to ensure proper underlayment, flashing, ventilation / drainage, and edge / overhang installation — per code and manufacturer specs.

• Local zoning / HOA / fire-safety requirements permit it, and the roof covering is correctly labeled and certified per state code.

If you decide to use rolled roofing, treat it like a functional but modest roofing option — not a “set it and forget it” solution. Make sure the installation is done carefully and inspected properly, especially around edges, penetrations, and drainage points.
