CertainTeed Asphalt Shingle Roof Replacement in DC, Maryland, and Northern Virginia
DC Metro’s Trusted Source for Asphalt Shingle Roofing
Serving the DC Metro area since 1956, Alco Products is a third-generation, family-owned roofing company and a select CertainTeed Select ShingleMaster. If your home is due for roof replacement, CertainTeed’s durable asphalt shingle roofing system is a smart choice. Your new roof installation will follow the Alco Integrity Roof System, our proprietary framework for building each roof from the deck up, and will be backed by our signature limited lifetime labor warranty.
What separates a reliable roof from one that fails early is everything installed beneath the shingles. The Alco Integrity Roof System ensures each layer works together to protect your home over time. This system covers all aspects of roof assembly:
Upgraded Sheathing: A properly prepared, solid roof deck that gives shingles a stable foundation
High-Performance Underlayment: A secondary moisture barrier installed between the sheathing and shingles
Ice and Water Shields: Applied at eaves, valleys, and other vulnerable areas to help block water intrusion
Professional Flashing: Installed around chimneys, skylights, and roof transitions to seal critical edges
Vent and Ridge Caps: Finished with precision to protect the roof’s perimeter and peak
Smart Ridge Venting: Supports consistent attic airflow to help manage heat and moisture
Finishing Trim: Final detailing that completes a clean, uniform installation
Other CertainTeed roofing contractors may install the same shingles, but what sets Alco Products apart is the installation system behind it. That’s why so many homeowners across Washington, DC, Maryland, and Northern Virginia continue to choose us for their roof replacement needs.
CertainTeed Asphalt Shingle Options for Metro DC Homes
Alco Products offers two primary asphalt shingle options: architectural laminate shingles and 3-tab shingles.
Architectural laminates feature multiple bonded layers, creating a textured surface that resembles wood shake or slate without the weight or maintenance demands.
3-tab shingles have a flatter, traditional look suited to homes where a classic appearance and tighter budgets are priorities.
CertainTeed’s Select ShingleMaster Designation: What It Means for You
CertainTeed’s Select ShingleMaster designation speaks to our roofing installation expertise and ongoing training with CertainTeed systems. For homeowners, this certification matters because it provides access to enhanced manufacturer warranty coverage not available through many other roof contractors.
Beyond the manufacturer’s product warranty, Alco Products provides a limited lifetime labor warranty on every CertainTeed roof we install. That warranty applies to our workmanship, not just the shingles themselves.

Featured Customer Review
Professional and Delivered on Promises - My wife and I chose Alco for a full exterior renovation in 2020. They installed an entirely new roof system, gutters, AZEK trim, and Fiber cement siding. ALCO delivered on every promise they made when we went to contract. The timeline and costs were accurate and the quality of workmanship was terrific. Friends and neighbors still tell us how wonderful the house looks! Thanks ALCO!

Common Questions About CertainTeed Shingle Roofing in DC, MD, and VA
