Protecting What’s Above — and Everything Below
Criterium-Williams Engineers provides roof system evaluations for multifamily and commercial buildings. We visually assess shingles, tile, slate, metal, and low-slope membrane systems (BUR, modified bitumen, TPO, EPDM, PVC, and coatings) to document existing conditions and identify issues affecting watertightness, drainage, durability, and remaining service life. Owners and associations use our findings to support informed decisions regarding repairs, maintenance, and replacement.
Why Roof Evaluations Matter
Roofs are among a building’s most critical and costly assets. In Texas, intense sun, wind, and heavy rainfall accelerate roof wear and deterioration. Early evaluations can help identify issues before interior damage occurs or premature replacement becomes necessary.
Typical Evaluation Scenarios
- Active leaks or moisture intrusion
- Aging or weathered systems / service life questions
- Storm or hail damage
- Ponding or poor drainage
- Membrane, flashing, or penetration failures
- Re-roof or renovation planning
Our Approach
1. Review drawings, owner roof warranties, and repair history
2. On-site visual inspection (optional moisture/thermal testing)
3. Diagnose deterioration and risks
4. Report with prioritized recommendations
5. Optional reroof design, bid support, and construction observations
