Overview
For commercial buildings with sloped rooflines, architectural shingles and concrete or clay tile systems deliver proven long-term waterproofing with more design flexibility than low-slope membrane alternatives. Steep-slope systems are appropriate for buildings with a minimum pitch of 2:12 (shingles) or 2½:12 (tile) and are the standard specification for churches, restaurants, office buildings, retail centers, and mixed-use developments across the Kansas City region. Evangel installs commercial-grade architectural shingles and tile systems using GAF-certified practices with full manufacturer warranty eligibility on qualifying projects. Every steep-slope engagement begins with slope verification and — where concrete or clay tile is specified — a structural load assessment to confirm the deck can support the added dead load before any material is specified.
Key Benefits
- Class 4 impact resistance (UL 2218) — the highest available rating — reduces hail damage in Kansas City's active hail corridor and may qualify facilities for insurance premium reductions of 20–35%
- Class A fire-rated assemblies available across architectural shingle and tile product lines
- Concrete tile rated 40–60 years; clay tile rated 75+ years — outlasting most single-ply membrane alternatives
- Structural dead-load assessment included when tile is specified — concrete tile adds 9.5–12 lbs per sq ft, clay tile 7.5–14 lbs per sq ft depending on profile
- Architectural shingles specified at 300–430 lbs per square, significantly heavier and more durable than standard residential weights
- GAF-certified installation enables manufacturer warranty eligibility on qualifying shingle and tile projects
Best Suited For
Churches and religious facilities, restaurants and hospitality properties, retail centers with pitched rooflines, office buildings with architectural requirements, mixed-use commercial/residential developments, and historic or institutional buildings where steep-slope aesthetics and long service life are both priorities.
