Build a useful record of the current roof
Gather existing roof plans, warranty documents, maintenance reports, and previous repair invoices. Identify recurring leak locations and note any relationship to weather or rooftop equipment work.
The assessment should consider the roof covering, transitions, drainage, and relevant underlying conditions. Some questions may require further investigation before the full scope can be established. Ask what is known, what remains uncertain, and how those uncertainties will be resolved.
Compare repair, restoration, and replacement
These are different approaches with different purposes. A localized repair addresses a defined problem. A restoration system requires an existing roof suitable for that system. Replacement addresses a broader scope and may involve underlying components.
Ask what evidence makes an option appropriate for the building. A coating should not be presented as a universal answer, and an aging roof should not be assigned a solution on age alone.
- Condition findings and supporting photographs
- Scope of work and areas excluded
- Moisture or substrate questions requiring investigation
- Drainage and penetration details
- Applicable manufacturer documents
- Completion and maintenance requirements
Make the occupied building part of the plan
Tell the contractor about sensitive equipment, tenant hours, public entrances, delivery routes, parking, and any work that cannot be interrupted. Identify the person authorized to approve changes and the people who need progress updates.
Discuss work zones and communication before the start. Ask whether the proposed schedule needs sequencing around other trades or building activities. Any accommodations should be confirmed for the project rather than assumed.
Keep the proposal useful after installation
The finished project should leave the owner with a clear record of the agreed work, product information, applicable warranty documents, and care requirements. Establish who will keep those records when a facility manager or tenant changes.
If several buildings are being evaluated, use a separate condition record and scope for each. That makes it easier to distinguish a current repair need from future planning and to compare options across the portfolio.
Your questions, answered
Can my existing commercial roof be coated?
Suitability requires assessment of the existing assembly, moisture conditions, adhesion, drainage, and the proposed coating system. A coating is not appropriate for every roof.
Can the work be planned around tenants?
Share occupancy and access requirements during scoping. Any schedule or access accommodation needs to be agreed for the particular project.
What documents help with a commercial assessment?
Roof plans, previous scopes, warranties, leak logs, and maintenance records help establish the roof’s history and open questions.
