Roof Performance Management

Assessments, debris clearing and scheduled roof visits

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

For low-slope commercial, multi-residential and industrial roofs.

Core Offering

What the assessment covers

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

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.

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 debris clearing and correction are targeted where flow is actually restricted.

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.

Debris Clearing

Where needed, we remove debris visibly obstructing drain strainers, scuppers and overflows during the assessment, along with leaves, needles, moss and silt across the roof. Every drain is photographed before and after.

Clearing debris restores effective drainage, maximizing roof performance through regular, documented care.

We don't snake or jet drain lines, wash roofs or carry out repairs. Where further work is needed, we point you to the right trade.

Scheduled Roof Visits

A visit schedule built for each roof

Your first assessment establishes your Roof Performance Baseline and how often the roof should be visited. Exposure to environmental threats sets the schedule, so each roof gets the attention it needs.

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.

Drainage Monitoring

Sense Smart Roofs

Where drainage vulnerabilities are observed during the assessment, ongoing visibility between visits can be an optional add-on to the package. As a local partner, GuardRoof can support installation and first-line support for the Sense DSW water level sensor on the Sense Smart Roofs platform.

The sensor sits at the drain and monitors standing water, providing an early alert when water levels begin to rise and drainage may be compromised.

  • Reads the water level every 60 seconds
  • Alerts by SMS, email, and push at warning and critical thresholds
  • Wireless and non-invasive
  • Installed without fastening or bonding to the membrane
