A Landmark Colonial Slate roof combines the layered look of architectural shingles with a cool mix of gray, charcoal, and subtle blue-toned color. The name can be confusing: Colonial Slate is a shingle color, not a slate roofing material. Landmark shingles are made with asphalt and fiberglass. Understanding the product, its appearance, installation requirements, and warranty can help homeowners compare estimates and decide whether this roof suits their home.
Asphalt roofs benefit from periodic visual checks, especially after severe weather. Homeowners can look for missing or visibly damaged shingles from the ground, but should avoid climbing onto the roof. A qualified roofer can inspect areas that are difficult or unsafe to access, including flashing, valleys, and roof penetrations.
Keep gutters and downspouts clear so water can drain properly. Remove debris that accumulates in roof valleys when it can be done safely, and trim branches that rub against the roof or drop heavy debris. Moss or algae may occur in some conditions; cleaning methods should be compatible with the shingle manufacturer’s guidance. High-pressure washing can damage asphalt shingles and should not be used without explicit professional approval.
Repairs to a weathered Colonial Slate roof may be difficult to match exactly. Sun exposure, dirt, and normal aging can make replacement shingles look different from the existing field, even when the same color is available. A roofer can assess whether a localized repair is practical or whether a larger section needs attention.
Questions to Ask Before Ordering
- Is the quoted product specifically CertainTeed Landmark in Colonial Slate? Ask for the product name and current specification sheet in writing.
- What does the estimate include? Confirm tear-off, disposal, underlayment, flashing, ventilation, permits, and any anticipated decking work.
- Who will install the roof? Verify licensing where required, insurance, relevant experience, and any manufacturer credential used for a warranty program.
- Which warranty applies? Request the actual manufacturer warranty and the contractor’s separate workmanship terms.
- Can the color be seen at full scale? Review a large sample, color visualizer, or nearby installation before approving the order.
- How will unforeseen damage be handled? Agree on documentation and approval procedures for additional work discovered during tear-off.
Reliable Sources for Product Decisions
The most dependable starting point is CertainTeed’s official roofing product information, including current Landmark specifications, color resources, installation instructions, and warranty documents. Product pages and documents should be checked directly because available colors and technical details may change.
For installation and contractor selection, homeowners can also consult local building departments and established roofing-industry organizations such as the National Roofing Contractors Association. Local code officials can clarify permit and code requirements, while the manufacturer’s instructions establish product-specific installation guidance. Together, these sources help separate verified specifications from marketing descriptions and outdated online claims.
