Roof condition and structural appraisal across a commercial portfolio
A rolling programme of roof condition surveys and structural roof appraisals, each site receiving both a condition report and a separate structural appraisal.
What the project needed.
Portfolio owners needed to know two different things about each roof: what structural capacity it has, and how much serviceable life the covering has left. Those are separate questions and they were reported separately.
Work carried out
- Roof condition survey per site
- Structural roof appraisal report per site
- Assessment of existing roof structure and capacity
- Reporting in a consistent format across the portfolio
- Sites across England and Scotland
What roof appraisal programme actually involves.
Every site in the programme received two documents: a roof condition report and a structural roof appraisal. Keeping them separate is deliberate. Condition governs when the covering needs replacing. Capacity governs what can be put on it. A roof can be structurally adequate and near the end of its serviceable life, or in good condition and unable to take additional load, and conflating the two produces the wrong decision.
Reporting to a consistent format across the portfolio means the sites can be compared against each other and a programme built from the results, rather than each report standing alone.
This is the same assessment that governs whether a roof can carry solar PV, which is why the structural appraisal is worth having before an installation is specified rather than after.
