What the Photo Identifier Will Tell You
You see a beautiful metal roof in your neighborhood and wonder: what exactly is that? Is it standing seam or snap-lock? What color is that — Charcoal or Burnished Slate? Is it steel or aluminum? PVDF or SMP? These distinctions matter when you are specifying your own roof, and they are hard to determine from appearance alone.
The Metal Roof Photo Identifier will analyze your uploaded photo and tell you:
- Panel type: Standing seam (mechanical-lock or snap-lock), exposed-fastener (R-panel, PBR, 5V-crimp, corrugated), metal shingles, or stone-coated steel
- Approximate seam height and panel width based on proportional analysis
- Probable substrate: Steel (Galvalume or galvanized) or aluminum, based on visual cues like patina pattern and edge treatment
- Color identification: Closest standard manufacturer color name (e.g., "Burnished Slate," "Charcoal," "Coastal Blue")
- Probable coating system: PVDF or SMP, based on gloss level and surface characteristics visible in the photo
- Condition assessment: Approximate age and condition based on visible chalking, fading, and weathering patterns
How to Get Useful Identification Without This Tool
While we build the automated tool, here are manual identification tips:
Identifying Panel Type from the Street
- Standing seam: Raised vertical seams with no visible screws on the panel face. Seams are evenly spaced and run from eave to ridge.
- 5V-crimp: Shallow V-shaped ribs, typically 5 ribs per panel. May have visible fasteners at the rib tops or concealed fasteners depending on the system.
- R-panel / PBR: Trapezoidal (flat-topped) ribs with visible screws in the flat sections between ribs. Reads as commercial or agricultural.
- Corrugated: Sinusoidal (wave-shaped) pattern with visible fasteners at the rib peaks. Classic barn and industrial look.
- Metal shingles: Individual overlapping units that look like slate, tile, or wood shake from a distance. Look for the tell-tale uniformity that distinguishes stamped metal from natural materials.
- Stone-coated steel: Textured, granular surface that resembles concrete tile or clay tile. The giveaway is the weight — stone-coated steel panels are light enough that they do not require the heavy structural support that real tile needs.
Identifying Color and Coating
- High gloss and sharp color = newer PVDF coating. PVDF maintains gloss and color intensity for 20+ years.
- Moderate gloss with slight color softening = aged PVDF or newer SMP. Distinguishing these requires knowing the roof's age.
- Matte finish with visible chalking = older SMP coating. Run your finger on the surface — if white powder comes off, the SMP is well into its degradation phase.
- Metallic silver without paint = unpainted Galvalume or aluminum. Galvalume develops a spangle pattern (crystalline shapes in the surface). Aluminum is smoother and more uniform.
