Roof Resilience Assessment

Field Assessments for Climate-Resilient Roofs

A focused roof review for owners, managers, and insurers who need clear information they can act on.

Field-based assessments of low-slope commercial and multi-residential roofs.

Jump toWhat the assessment covers

A low-slope roof completely covered in standing water during an active storm — A roof area holding water it cannot release during active rainfall.

Design Vulnerabilities Under Extreme Rainfall

Many roofs still rely on drainage layouts sized for a different climate

When primary paths are restricted, water has nowhere to go. The assessment identifies those vulnerabilities and documents them with clear visual evidence.

Reviewing the primary drains and the emergency overflow drains together is the first step in understanding whether a roof can handle the rainfall it now receives.

What the assessment covers

Each review is conducted on the roof itself, structured around the conditions that most often lead to preventable roof failures.

Extensive ponding across a low-slope roof with vents and penetrations standing in water — Drainage & Emergency Overflow Review
Primary drain layout and capacity across independent roof areas, plus the presence, location, and sizing of emergency overflow drains, the secondary path that protects the roof when the main drains are restricted.
Confirms whether each roof area can actually clear the rainfall it now receives, and where a second path out is missing.

Roof drain submerged in standing water surrounded by a ring of accumulated debris — Ponding & Debris Risk
Identification of blockage points, debris sources, and conditions that contribute to prolonged ponding and the bathtub effect, including roof areas served by a single drain.
Drainage capacity is only as good as the drain that is open, so cleaning and correction are targeted where flow is actually restricted.

Looking down a short fixed ladder through a roof access hatch with no grab bar at the opening — Access & Maintainability
On-site evaluation of roof access and the ability to inspect and maintain primary drains and emergency overflow drains under current conditions.
A roof that is difficult to reach is a roof that is rarely checked, and drainage problems build quietly between storms.

Supporting Deliverables

Clear documentation for decision-makers

Prioritized findings for capital planning and risk decisions, written so owners, managers, and insurers can act on them directly.

Priority Actions Summary

Concise, ranked recommendations focused on the highest-risk items first, timed where possible with existing capital work.

Roof Mapping

Labeled plans of independent roof areas and drain locations, a shared reference for owners, managers, and contractors.

Stakeholder Support

Documentation that supports discussions with boards, insurers, and technical consultants on foreseeable risk.

Collaborative Approach

We identify issues and point to the right specialists (plumbers, roofers, or engineers) when further work is required.
