NR Building Solutions

For commercial property owners

Roofing is a capital item you deal with once a decade per building, which means you are negotiating from a standing start against a contractor who does this daily — and the bids in front of you are not comparable.

Request a roof survey
  • A portfolio roof survey before any bid, with a repair-or-replace call per roof

  • Specification stated plainly, so bids can actually be compared

  • Maintenance programmes that defer replacement rather than only reporting on it

  • One vendor agreement across commercial assets and manufactured housing communities

You are negotiating from a standing start

A commercial roof is a capital decision you make roughly once a decade per building. The contractor across the table makes it daily.

That asymmetry is the actual problem with commercial roofing procurement, and it shows up as three bids that differ by a large multiple with no way to tell which one is right.

Why competing bids are not comparable

They are almost never comparable, because they usually describe different roofs.

Membrane thickness45, 60 or 80 mil. A real difference in how the roof ages, and a real difference in price.
Attachment methodMechanically attached, fully adhered or ballasted — a wind-uplift and deck decision, not a preference
InsulationR-value and whether a tapered system is included to correct drainage
Tear-offIncluded or not, and how many existing layers are assumed
DetailingWhat happens at every curb, drain, penetration and termination — where roofs actually fail

Two honest bids on the same building can differ substantially if they specify differently. The question to ask is not "what is your price per square." It is "what did you specify, and why that." A contractor who cannot answer the second question in specifics is quoting a number rather than a roof.

Our position on each of these is stated openly on the TPO and metal and recoat pages, including installed cost ranges.

Survey before you bid

Bidding every roof in a portfolio as though all of them need replacing is easy to arrange and expensive to buy.

  1. Survey

    Every roof: condition, remaining service life, and a repair-or-replace call with photographs.

  2. Triage

    Which roofs need work this year, which can be maintained, and which can wait — with the reasoning for each.

  3. Programme

    The work that must happen, phased across the budget cycle, with maintenance covering the rest.

A survey saying three of fourteen roofs need work this year is worth more than fourteen replacement bids. It is also the smaller first invoice for us, which is the reason to trust the recommendation.

What maintenance is for

A maintenance programme is not about the visit. It is about keeping roofs in service and off the replacement list.

A blocked drain creating ponding, a lifted termination, an open seam: each is a small repair on the day and a larger one once water has reached the insulation. And on buildings with rooftop equipment, a large share of the damage is not weather at all: it is technicians walking the membrane and cutting through it to run conduit.

See maintenance programs.

One vendor across both asset types

Most owners who come to us for commercial roofing also own manufactured housing communities, or the reverse.

One agreement, one vendor file, one invoicing stream, one reporting standard, across both. Running a separate vendor file for the clubhouse roof and the community renovation is administrative overhead that buys nothing — see national accounts.

Common questions

Almost always because they describe different roofs. Membrane thickness, attachment method, insulation, tear-off and detailing all move the number substantially, and a bid that does not state them is not comparable to one that does. The useful question is not price per square — it is what was specified and why.

Yes, and it is the step most often skipped. Bidding every roof in a portfolio as though all of them need replacing is easy to do and expensive to buy. A survey that says three of fourteen need work this year is worth more than fourteen replacement bids, even though it is the smaller first invoice.

That is what it is for. A blocked drain creating ponding, a lifted termination or an open seam is a small repair on the day and a larger one once water is in the insulation. Regular visits catch them early, so a roof can stay in service instead of moving onto the replacement list.

That is the usual reason owners come to us. One agreement, one vendor file, one invoicing stream across both asset types, with the same reporting standard. Running two vendor files for roofing work is administrative overhead with no benefit.
