Commercial landlords & REITs
Roof and facade failure is the cost that arrives without warning and the deferral nobody can defend. Ovrsite gives asset managers one current view of envelope risk across the portfolio, and a CAPEX plan that survives a board.
01 The problem
The roof is where the surprises live.
Across a commercial portfolio, the building envelope drives the unplanned spend. A failed flat roof becomes water in a let unit, a rent dispute, and an emergency contractor at a premium. The condition data you hold was usually written by whoever last quoted the repair.
Meanwhile the deadlines stack up. Minimum energy efficiency standards tighten, lease events arrive, and acquisitions need diligence in days, not weeks. Each one asks the same question: what condition is this asset actually in?
02 Plain answers
The deadlines and duties behind the spend.
What is MEES, and when do the standards tighten?
The current non-domestic minimum EPC standard is E, subject to the rules and exemptions that apply. The government’s June 2026 interim response proposes EPC B from 2031 for rented buildings over 1,000 square metres where cost-effective, retaining E below that threshold. The proposed 2027 EPC C milestone will not proceed. The changes require secondary legislation. Building-condition evidence informs a retrofit plan; an accredited assessor produces the EPC.
Why does working at height matter to cost?
The Work at Height Regulations 2005 require you to avoid work at height where it is reasonably practicable. A drone inspection often achieves the same result without putting a person on the roof, which can reduce the need for roof access for that capture; site controls and any further investigation remain separate.
03 How Ovrsite helps
One record that works across the whole hold period.
Inspect the portfolio once a year and Ovrsite Enterprise holds the trend. You see which roofs are deteriorating, which need further investigation, and where next year's capital should land. At acquisition, a fast envelope capture tells you what you are buying before you commit. At a lease event, the condition record supports the dilapidations position.

Commercial portfolios, answered
Can you inspect a large, dispersed portfolio?
Yes. We plan multi-site capture as a programme, with consistent grading and reporting across every asset, so the agreed portfolio programme uses a consistent reporting structure rather than a stack of separate reports.
Does a thermal inspection give us an EPC or MEES rating?
No. An EPC is produced by an accredited assessor under a separate process. Thermography can identify temperature patterns that warrant further investigation, which informs the retrofit and MEES strategy. It supports the energy case rather than replacing the certificate.
How quickly can you turn around acquisition due diligence?
Tell us your diligence deadline. We review the building, required outputs and operating constraints before confirming a programme.
Will this stand up with our lenders and valuers?
Reporting follows a consistent, evidence-led structure. Findings are dated, located and reviewed by our team before release, so the report can be put in front of a lender, a valuer or a board.
Know the envelope before it costs you.
Tell us about your portfolio. We will fly one asset, return graded findings and a costed plan, and show you how it reads across the whole estate.
