Compare the system, not just the membrane.
The right commercial system depends on the building, existing roof, drainage, insulation, traffic, operations, and ownership plan.
You do not need to choose a system before contacting us.
TPO
Reflective single-ply
Typical upfront investment
Relative only. Not a quote.
Usually makes sense when
A reflective single-ply membrane and heat-welded seams fit the building and approved assembly.
What you gain
- • Reflective surface
- • Heat-welded seams
- • Efficient coverage of large low-slope areas
What you give up
- • Traffic and puncture protection matter
- • Details and installation quality are critical
These are decision examples, not a specification. WalterGC should confirm the system that fits the actual property and approved project requirements.
What protects your property
A good roof is more than what you see.
You pay for materials, preparation and work that will be hidden. Value comes from the right specification and installation—not automatically the highest or lowest price.
01Membrane / surface
The weather surface works with its seams, penetrations and drainage.
What affects cost: Materials, waste, roof shape and skilled labor. A pricier surface cannot fix poor installation.
02Seams & waterproofing
Waterproofing includes membrane seams and transitions; it is not always a separate layer.
What affects cost: Surface preparation, compatible products and careful work before these details disappear.
03Insulation, support & attachment
Insulation, cover board and attachment are specified for the building and approved system.
What affects cost: Attachment design, wind requirements, compatible components and correct installation.
04Deck / structure
The roof needs a sound base. A new surface cannot repair damaged decking underneath.
What affects cost: Tear-off, access, evaluation and necessary repairs. Hidden conditions are documented and scope changes agreed.
05Flashing & critical details
Edges, walls, valleys, penetrations and drains need continuous protection.
What affects cost: Careful work at each transition and quality checks—not just square feet of material.
Compare the scope, not just the total.
Permits, inspections, access, property protection, tear-off, disposal and cleanup also take work. Ask what is included, excluded, and how hidden repairs and warranty are handled. Age alone does not mean replacement: condition, remaining life and a sound repair option matter.
