Wood Roofing: What Gainesville Homeowners Need to Know for High-Slope Installations

When it comes to roofing your home in Gainesville or surrounding towns like Dahlonega, Flowery Branch, or Cumming, wood roofs can offer a timeless, natural beauty you won’t find with synthetic materials. But not all roofs are right for wood—and not all installers handle them properly.

Here’s what you need to know before choosing wood roofing for your high-slope home.

Why Choose Wood Roofing?

Wood shakes and shingles have been trusted for generations—and for good reason. When installed correctly, they offer:

• Natural curb appeal that weathers into a beautiful silver-gray tone

• Excellent insulation properties for hot summers and cold winters

• Wind and impact resistance, especially when using thicker, premium-grade shakes

• Sustainability, when sourced from certified mills like those under the Certi-label™ brand

Best Use: High-Slope Roofs

In Gainesville, we recommend wood roofing for high-slope applications only (4:12 pitch or steeper). Why?

Because wood needs gravity’s help to shed water. Shakes and shingles aren’t waterproof—they’re water-shedding. Steeper slopes improve drainage and reduce the risk of water penetration and premature decay.

Installation Musts for Longevity

Wood roofs must be installed with precision and code-compliance. At L&L Roofing, we follow the Cedar Shake & Shingle Bureau (CSSB) and IBC 2021 code standards.

Here’s how we do it right:

1. Proper Spacing and Ventilation

• Each shake is spaced for swelling/shrinkage and to prevent water damming.

• We ventilate beneath the wood using skip sheathing or vented underlayments to avoid moisture buildup and rot.

2. Quality Materials Only

We only install Certi-label™ shakes and shingles. These are:

• Handsplit & Resawn Shakes for a rustic look

• Tapersawn Shakes for a more tailored shadowline

• Sawn Shingles for a clean, uniform appearance

3. Right Fasteners & Flashing

• Hot-dipped galvanized or stainless steel nails only

• Step flashing at every sidewall and chimney penetration

• Ice barrier membranes at all eaves, valleys, and dormers

Know the Local Code (Yes, It Matters)

Under the IBC 2021 and Georgia's amendments, wood shakes and shingles must:

• Be installed over solid or spaced sheathing depending on fire rating

• Meet wind resistance criteria

• Be treated or naturally durable species in WUI or high-risk areas

At L&L Roofing, we always build to code—and often beyond it.

How Long Will a Wood Roof Last?

With proper installation and care:

• Shakes last 30–40 years

• Shingles last 20–30 years

But your actual lifespan depends heavily on:

• Ventilation

• Slope

• Tree coverage and debris

• Regular maintenance

Common Questions

How often should I clean a wood roof?
Once or twice a year—especially after fall. Remove moss, debris, and check for damaged shakes.

Can I install solar on a wood roof?
Yes, but we recommend pre-planning the mounting system before installation to avoid future issues.

Are wood roofs fire safe?
Class C is standard, but we offer Class A assemblies with underlayments and fire-retardant treated shakes.
