Protect the building. Plan around the business.

Plan the roof around the business

A useful commercial scope accounts for occupants and operations as well as waterproofing. Begin with the problem, the areas affected and what must keep operating. Separate the assessment, design decisions and construction authorization.

Prepare a building brief

• Roof plans or approximate areas, known materials, repair records and warranties. Unknown details can be identified during the agreed assessment.
• Occupancy, tenant contacts, operating hours and sensitive spaces or inventory below.
• Rooftop HVAC, grease/chemical exposure, solar equipment and responsible service vendors.
• Access restrictions, loading/storage locations, parking and deliveries.
• Recurring water entry, outlets and known drainage/overflow concerns.

Compare the project paths

• Targeted repair: define the defect and repair boundary, plus surrounding conditions left in place.
• Restoration: require suitability findings, moisture/adhesion assessment and separately defined repairs.
• Recover: evaluate existing layers, loading, compatibility and applicable design requirements before assuming retention is acceptable.
• Replacement: define removal, deck/insulation, attachment, perimeter and drainage as a complete assembly.
• Phased work: define temporary weather protection, tie-ins and responsibility between phases.

Control disruption before work starts

• Agree who communicates with tenants, which access routes stay open and when noisy or odorous work can occur.
• Define equipment protection, shutdown coordination and who may disconnect/reconnect systems.
• Set weather contingencies, daily closure expectations and protection of occupied spaces.
• Document unforeseen-work pricing and written authorization by the owner’s named representative.

Build a useful maintenance and budget record

Keep a roof-area map with dated observations, work completed, access by other trades and unresolved concerns. Ask for a condition-based distinction between prompt attention, planned work and monitoring. A maintenance plan is not automatic authorization for unlimited repairs.

• Current repairs: defined findings and price.
• Planned renewal: assumptions, dependencies and a review date.
• Optional improvements: separate cost and reason.
• Contingencies: agreed approval rules, not a hidden promise of a fixed final cost.

Ask for a completion package

• As-built product/assembly identification and permitted work records where applicable.
• Concealed-detail and finished-work photographs where included.
• Warranty documents and the responsible contact for a problem.
• Maintenance/access guidance and equipment-vendor coordination notes.
• A list of excluded areas or remaining conditions.
