TPO Roofing

Residential journey

• Low-slope additions and modern homes
• Reflective roof goals
• Roofs with manageable penetrations

Commercial journey

• Retail, offices, warehouses, and multifamily
• Occupied-building phasing
• Recover or replacement evaluations

Suitability checks

• Slope, deck, drainage, ventilation, and structural capacity must support the assembly.
• Wind, salt, hail, heat, snow, fire, and local code exposure affect product and fastening choices.
• An inspection is needed before deciding between repair, restoration, recover, or replacement.

Cost drivers

• Membrane thickness and attachment method
• Insulation, taper, drainage, and deck condition
• Penetration and edge-metal complexity
• Tear-off, crane, access, and occupied-building controls

Typical project sequence

Duration is confirmed after scope, lead times, permits, weather, access, cure requirements, and hidden-condition allowances are known.

1. Core cuts and moisture survey when appropriate
2. Drainage and assembly design
3. Phased tear-off or preparation
4. Membrane welding, detail checks, and closeout

Scheduling

A coordinator confirms material lead times, permits, safe access, weather windows, and any business or household constraints before setting the installation date. Emergency stabilization is scheduled separately from permanent work.

Maintenance

• Schedule professional inspections after major storms and at intervals appropriate to the system.
• Keep drains, gutters, valleys, and roof edges clear; address sealant or flashing changes promptly.
• Document authorized repairs and avoid unapproved penetrations that may affect warranty coverage.

If water is entering now

1. Keep people away from active leaks, sagging ceilings, and downed electrical lines.
2. Move valuables and use containers only when it is safe; do not climb onto a wet or storm-damaged roof.
3. Photograph visible damage from the ground and note when the leak started.
4. Call WHI for safe temporary protection and contact emergency services for immediate life-safety hazards.

Compare written scopes

• Photos and a written condition summary
• Scope showing materials, tear-off assumptions, deck allowances, and exclusions
• Permit, cleanup, protection, and scheduling responsibilities
• Manufacturer and workmanship warranty terms—not just headline durations
• Change-order process and final closeout documents

Warranty questions

Ask who issues each warranty, what it covers, when it starts, how coverage statements are made, whether it transfers, and which maintenance, registration, or inspection conditions apply.
