CertainTeed Symphony Slate Shingles: A Comprehensive Guide

The CertainTeed Symphony Slate shingles blend the aesthetic appeal of slate with the practicality of asphalt roofing. Marketed for homeowners seeking a premium look without the weight and cost of natural slate, Symphony Slate delivers durable performance, color variety, and a strong warranty. This article explores key features, installation considerations, maintenance, and value to help readers determine if Symphony Slate shingles fit their roof replacement or new build project.

Overview And Core Benefits

Symphony Slate is a laminated architectural shingle designed to mimic the depth and texture of real slate while offering the familiar benefits of asphalt shingles. It provides robust impact resistance, excellent wind performance, and a wide color palette. Homeowners gain a premium visual with a relatively straightforward installation process compared to heavier slate materials. The product is backed by CertainTeed’s strong warranties, which enhance long-term peace of mind for homeowners seeking durable curb appeal.

Key Features And Tech Specs

Symphony Slate features a dual-layer design that creates a dimensional look, with micro-engraved tabs and a blend of mineral granules to simulate slate’s variation. It offers:

  • Warranty Coverage: Typical Limited Lifetime warranty for mural-like performance, plus NDL (Non-Prorated) period on manufacturing defects in many installer programs.
  • Wind Resistance: Rated to resist high wind speeds when properly installed, aligning with most regional building codes.
  • Impact Resistance: Enhanced granule adhesion and flexible asphalt composition help resist hail and daily wear.
  • Color Longevity: Color blends designed to minimize visible fading over time.

Color And Style Options

Symphony Slate comes in a curated slate-inspired palette that pairs well with modern and traditional homes. Common color families include charcoal, gray, blue-gray, and taupe variants, each with multi-dimensional shading. The Aesthetic flexibility allows homeowners to achieve a refined roofline that complements brick, wood, stucco, or siding materials. It’s important to view actual shingle samples and consider regional lighting, as color perception can shift under sunlight throughout the day.

Durability, Weather Performance And Life Expectancy

Durability hinges on asphalt shingle construction, proper attic ventilation, and correct installation. Symphony Slate is engineered to resist:

  • Weather Extremes: Cold cracking and heat-induced curling are mitigated by the product’s flexible asphalt composition.
  • UV Degradation: Mineral granules shield the asphalt base from sun exposure, helping maintain appearance and performance.
  • Water Ingress: Overlapping tabs and adhesive seals reduce water penetration in typical rain or light snow conditions.

With standard climate conditions in the U.S., homeowners can expect a lifespan in the 25–40 year range, depending on installation quality, roof pitch, ventilation, and maintenance practices. Regular inspections can catch early signs of moisture intrusion or compromised granules, extending the roof’s service life.

Installation Considerations And Best Practices

Proper installation is critical to achieving the expected performance of Symphony Slate shingles. Key considerations include:

  • Roof Pitch: A minimum slope is generally required to ensure adequate water shedding; confirm local code requirements.
  • Nail Pattern And Fasteners: Use the recommended nails in the correct pattern to prevent wind uplift and tab lift.
  • Underlayment: A quality underlayment layer provides additional moisture protection and helps reduce wind-driven leaks.
  • Ventilation: Adequate attic ventilation minimizes heat buildup and extends shingle life.
  • Professional Installation: Certified installers familiar with CertainTeed products typically achieve the best warranty outcomes and performance.

DIY attempts are not advised for slate-look shingles due to the need for precise nailing and alignment, particularly on complex roof geometries.

Maintenance, Care And Repair

Routine maintenance preserves curb appeal and performance. Recommended tasks include:

  • Annual Inspections: Look for lifted tabs, damaged flashings, or granule loss, especially after severe storms.
  • Gutter Cleaning: Prevents gutter overflows that can back up onto the roof edge and fascia.
  • Moss And Algae Control: In shaded regions, treatments or preventative measures help avoid moisture retention that can degrade aesthetics.
  • Stain Management: Address staining from nearby trees or debris to maintain the slate-like appearance.

Repairs should generally be performed by licensed roofers to avoid compromising the shingle system and warranty.

Warranty, Service And Support

Symphony Slate warranties typically align with CertainTeed’s product protection framework, offering:

  • Non-Prorated Coverage: A period during which manufacturing defects are covered without reduction over time.
  • Prorated Coverage: Beyond the non-prorated phase, coverage may diminish with age, subject to conditions and maintenance.
  • Transferability: Some warranties survive ownership changes, which can add value for future buyers.

Customers should review the exact terms in the warranty booklet provided by the contractor or CertainTeed, including exclusions related to improper installation or lack of maintenance.

Cost, Value And Return On Investment

Symphony Slate sits in the premium segment of asphalt shingles. While the initial cost is higher than standard architectural shingles, the visual appeal, durability, and potential for higher resale value can offset the expense. Factors influencing total cost include roof size, complexity, local labor rates, and whether additional elements such as ice barrier, ridge venting, or flashing upgrades are needed. A professional estimate will give a precise price, but homeowners should anticipate a moderate premium over builder-grade shingles and a meaningful upgrade from basic asphalt options.

Environmental Considerations And Recycling

Asphalt shingles are often recyclable into new products, reducing landfill impact. CertainTeed participates in recycling programs where available, and Symphony Slate may contribute to sustainable building practices when disposed of responsibly at end of life. Homeowners interested in green building should inquire about recycling options with installers and check for local programs that accept asphalt shingles.

Comparisons With Similar Roof Shingle Lines

When evaluating slate-inspired options, homeowners may compare Symphony Slate with other architectural shingles offering slate aesthetics. Consider differences in:

  • Texture And Dimensionality: How closely the product mimics natural slate’s depth and variation.
  • Warranty Terms: The specifics of non-prorated and prorated coverage and transferability.
  • Color Range: Availability of lighter or darker palettes to match home design.
  • Wind And Impact Ratings: Regional suitability based on climate and local codes.

The best choice balances appearance, performance, warranty confidence, and total cost of ownership over the roof’s life.
