Investigate before finalizing the scope
Moisture testing or selected openings may be useful. Agree the investigation and how its findings inform the quantities.
A new system over a suitable existing roof can reduce removal and disposal. That option depends on the existing layers, moisture, attachment, structural conditions and the applicable code. It is not available simply because it would cost less.
Where material is wet or deteriorated, its extent and repairability matter. Limited affected areas and widespread assembly failure lead to different proposals. Our roofers can assess the roof and discuss the investigation needed to support the recommendation.
A structurally sound roof with a compatible surface may also merit a coating assessment. Compare that possibility before treating replacement as settled.

Identify the deck and the condition the new system requires. Include a method for dealing with concealed damage.
Look at slopes, low areas, primary outlets and overflow arrangements. A new membrane alone will not change where water collects.
Confirm the specified thermal assembly and any tapered work. Existing wet material needs an appropriate disposition.
Compare the membrane or other system against the building use, equipment and manufacturer’s requirements. The commercial overview explains the main categories.
Curbs, walls, edges and drains need complete, compatible details.
A unit that must be lifted or piping that must be moved changes the project. Include that coordination in the scope.
Moisture testing or selected openings may be useful. Agree the investigation and how its findings inform the quantities.
Identify delivery, lifting and disposal arrangements and any impact on tenants or customers.
Discuss how areas will be opened and protected, including the response to weather changes.
Coordinate the specified roof layers, equipment and drainage work.
Confirm inspections, project documentation, maintenance information and the actual warranty or guarantee offered.
Only when the existing assembly and the applicable code and manufacturer requirements allow the proposed recover. Existing layers and moisture need to be established. Discuss those conditions before comparing a recover price with a tear-off price.
They may include different insulation, drainage corrections, removal quantities, deck allowances, attachment or equipment work. Ask what each proposal assumes before treating the lower number as the same job.
It should follow the drainage design included in the project. If an existing low area is a concern, make sure the proposal addresses its cause. A covering change alone may leave the same water pattern.
The roof area, complexity, access, required trade coordination and weather all affect duration. Ask for the proposed sequence and what can change the schedule.
No. Coverage depends on the program, cause and exclusions. Manufacturer system guarantees may include workmanship, while others cover products more narrowly. Read the exact document with the proposed assembly.
