When most homeowners in Harford County think about a new roof, they usually focus on the color and style of the shingles. It makes sense—that is the part you see from the curb! However, your roof is much more than just a layer of asphalt.
At Mid Atlantic Gutters and Roofing, LLC, we believe a roof is only as strong as its foundation. A truly durable, waterproof roof requires an “Integrity Roof System”—a multi-layered defense designed to protect your home from the unpredictable Maryland weather.
If you are only replacing shingles and ignoring what is underneath, you are only doing half the job. Here is a look at the critical components that keep your home dry and safe.
🛡️ The First Line of Defense: WinterGuard® Ice & Water Shield
In areas like Bel Air and Fallston, we are no strangers to heavy winter snow and the dreaded “freeze-thaw” cycle. This is where WinterGuard becomes the MVP of your roofing system.
What it is: A composite material of asphalt polymers that creates a tight seal.
What it does: It is applied to the most vulnerable areas of your roof—valleys, eaves, and around chimneys.
Why you need it: When snow melts and refreezes at your gutters, it creates an “ice dam.” This forces liquid water up under your shingles. WinterGuard acts as a waterproof barrier that prevents that backed-up water from seeping into your attic and causing costly interior damage.
🏃 The Secondary Shield: RoofRunner™ Underlayment
Once the edges and valleys are protected, the rest of your roof deck needs a high-performance cover. Traditional felt paper is a thing of the past. At Mid Atlantic Gutters and Roofing, we prefer RoofRunner.
Superior Toughness: Unlike old-fashioned felt, synthetic underlayment like RoofRunner is incredibly tear-resistant. It won’t rip or degrade if it’s exposed to wind or rain during the installation process.
Lays Flatter: It provides a much smoother surface for your shingles to lay on, which results in a cleaner, more professional-looking finished roof.
Extra Breathability: It is designed to let moisture escape from your attic while keeping outside water out, preventing wood rot in your roof deck over time.
📍 Why This Matters for Harford County Homeowners
Whether you are in a historic home in Havre de Grace or a newer development in Aberdeen, our local climate puts unique stress on your home.
The high humidity in the summer and the coastal winds coming off the Chesapeake Bay can drive moisture into tiny crevices. A “shingle-only” approach might look good for a year or two, but without a full Integrity Roof System, you are at a much higher risk for:
Mold and Mildew in the attic.
Wood Rot on the plywood decking.
Shortened Shingle Life due to poor heat and moisture management.
