Synthetic Roofing Underlayment: Better Protection for Your Georgia Roof

During Roof replacement, most of the attention goes to shingles—but what goes under those shingles matters just as much. That hidden layer is your roofing underlayment, and it’s your home’s last line of defense against water.

At Roof Nuts GA, we use synthetic underlayment—a modern upgrade from traditional felt—to give Georgia homes stronger protection against heat, humidity, and storm-driven rain.

What Is Synthetic Roofing Underlayment?

Synthetic underlayment is a water-resistant, lightweight sheet that’s installed directly over your roof decking and under the shingles. It acts as a moisture barrier and helps protect your home if shingles get blown off or damaged.

Made from high-strength polymers, synthetic underlayments are engineered for:

• Tear resistance

• Long-term UV protection

• Better traction for installers

• Water repellency

Compared to old-school black felt (tar paper), synthetics are lighter, stronger, and built to last.

Why We Use Synthetic Underlayment in Georgia

Georgia’s hot, humid climate and frequent storms demand better protection. Here’s why synthetic underlayment is the smart choice:

✅ 1. Water Resistance

Unlike felt, which can absorb water, synthetic underlayments repel moisture and don’t wrinkle or break down when wet.

✅ 2. Heat and UV Protection

Synthetics can resist UV rays for weeks without degrading—useful if bad weather delays your shingle installation.

✅ 3. Tougher and Tear-Resistant

They hold up better during installation and in high winds. That means fewer call-backs, and better long-term durability.

✅ 4. Safer for Crews

Synthetic surfaces provide better walkability, reducing the chance of installer injuries or accidents.

✅ 5. Lightweight and Efficient

A single roll of synthetic can cover more area than a roll of felt—saving labor and ensuring better seam coverage.

Our Installation Process at Roof Nuts GA

We follow best practices recommended by NRCA, IRC 2021, and major manufacturers like Owens Corning and Atlas.

Step-by-Step:

1. Deck Inspection
   We check the plywood decking for rot, soft spots, or nail pops. Any damaged decking is replaced before underlayment goes down.

2. Full Surface Prep
   We sweep and clean the decking, then install starter flashing and drip edge before laying underlayment.

3. Synthetic Underlayment Install
   We roll out synthetic underlayment (usually in 4’ wide rolls), overlap seams 4”, and fasten with cap nails for wind resistance.

4. Waterproofing Details
   We apply ice & water shield around valleys, chimneys, and penetrations for added protection—especially in leak-prone zones.

5. Shingle Installation
   Shingles are installed over the dry, protected surface—completing the weatherproof roofing system.

FAQ

💬 Is synthetic underlayment worth the upgrade?

Yes. It adds better moisture resistance, holds up longer, and gives your roof added protection during storms. Most modern shingle systems recommend or require it.

💬 Can synthetic underlayment be exposed to the sun?

Yes—for limited time. Most types are rated for 30 to 90 days of UV exposure, which is helpful if rain delays shingle installation.

💬 Is synthetic underlayment included with a full roof replacement?

At Roof Nuts GA, yes. We use synthetic underlayment as our standard, not an upgrade.
