Set the project goal
Record why the roof is being considered: replacement timing, known leaks, finish change, maintenance goals, solar planning or another property decision.
Penticton metal-roof planning
Compare the Whole Roof Assembly, Not Just the Panel
Profile the existing roof, compare system paths, document hidden layers and critical details, and turn proposals into an evidence-based decision.
Assembly bench
Follow one roof detail through every layer
Use the seams below as a compact submittal checklist for the proposed assembly.
Panel + attachment
Name the exact profile, seam, clip or fastener, substrate and movement detail.
Hidden layers
Connect deck evidence, underlayment, ventilation and transition compatibility.
Edges + openings
Resolve eaves, valleys, walls, penetrations, gutters and snow-slide context.
Choose the next decision
One property. Six distinct questions.
Start with the page that matches the uncertainty you need to resolve—not a preset solution.
01
Panel systems
A side-by-side record for panel attachment, seams, movement, geometry, penetrations, finish, maintenance and submittals.
Open guide →02Retrofit or tear-off
Organize existing layers, deck and moisture evidence, structural questions, ventilation, edge interfaces and approval dependencies.
Open guide →03Hidden assembly
Compare deck, air-vapour-thermal context, underlayment, ventilation paths, transitions and product documentation.
Open guide →04Snow & water details
Create a roof-detail map for water concentration, drainage, penetrations, access and areas below possible snow movement.
Open guide →05Wildfire evidence
Evaluate roof claims using current assembly listings, edge and opening details, adjacent materials and qualified review.
Open guide →06Quote checklist
Compare tear-off, deck allowances, underlayment, panels, flashings, ventilation, snow details, warranty evidence and records.
Open guide →Decision file
Build a clearer project record
Map roof geometry and exposure
Sketch slopes, valleys, walls, eaves, penetrations, trees, drainage points and areas below possible snow movement. Do not infer design loads from observation.
Compare systems, not labels
Standing-seam and exposed-fastener descriptions must include attachment, seam, substrate, flashing, finish and maintenance evidence.
Build the assembly record
Connect deck condition, existing layers, underlayment, ventilation, condensation control and edge details before comparing price.
