Medlock Bridge Architectural Shingle Roof Cost
Medlock Bridge is an established Johns Creek community where many homes are on their first or second roof. Architectural shingles are the standard choice, and most replacements follow the same pattern: tear-off, deck repair as needed, new underlayment, flashing and ventilation, then shingles.
This page helps you budget with published estimates and understand what drives the price.
What drives the price
Roof size in squares (100 square feet each), pitch and complexity, the number of layers to remove, decking replacement, flashing and chimney work, ventilation upgrades, and access. Two-story homes with steep, cut-up roofs cost more per square than simple ranch roofs. Published 2026 estimates put replacement at about $4–$11 per square foot and asphalt shingle roofs at $5,800–$20,000.
Shingle choices
Standard architectural shingles suit most homes and HOA guidelines. Impact-resistant (Class 4) shingles cost more but can earn insurance discounts with some carriers. Synthetic slate or metal are higher-priced options that usually need HOA review.
Realistic lifespan
Published estimates from Angi put asphalt shingles at 15 to 30 years and architectural shingles at up to about 30 years. In North Georgia's heat and humidity, a realistic planning range for a well-installed, well-ventilated architectural roof is about 20 to 30 years, with poor ventilation, heavy tree cover or hail pushing it toward the low end.
Permits and HOA
The City's Do I Need a Permit checklist lists a roof replacement with no structural work and up to 32 square feet of decking replacement as not needing a permit; structural alterations do. Medlock Bridge's HOA may require approval of color and product before work begins.
Comparing quotes
Ask for the same scope from each roofer: tear-off, decking allowance and price per sheet, underlayment, ice and water shield in valleys, flashing, ventilation, drip edge, cleanup, and workmanship warranty. Ask for license and insurance proof.
