The headline

Rapid mobilization: the most important thing we do

“Aaron Forsman’s commitment to Walter P Moore: our team can be on site anywhere within 6 hours of the call, and that capability is in place for Walter P Moore from day one.”

When a storm crosses a Walter P Moore client’s building, the first hours decide what can still be documented and protected. We screen the client’s buildings the same day, put our team on the Strong buildings first, capture dated photo evidence for your engineers, and provide temporary protection through our affiliated trades company only where the client authorizes it.

How we work together

Six steps, each one earning the next

Every step keeps the engineering opinion and the client relationship with Walter P Moore. We bring evidence and field capacity, and we give first.
A

Give first: the no-cost 25-building pilot

What Walter P Moore gets

One storm, 25 WPM-chosen buildings. By day 3: triage table (Strong / Moderate / Radar-only / Clear), a one-page record per building, a swath map, methods. By day 14: field documentation to WPM’s protocol, then a joint review. We also offer on-site walks of the top 5 or top 10 pilot buildings with your engineers. No cost; WPM holds every client.

What we need

A past storm date, 25 addresses, one named contact, the written field protocol, site access; a mutual NDA first if client data is involved.

First next step

Walter P Moore names the storm, the 25 buildings and a contact; we agree whether to walk the top 5 or top 10.

B

Pre-construction and acquisition due diligence

What Walter P Moore gets

A packaged due-diligence storm and roof file for each site, built to drop into Gary’s pre-purchase audits and repair/capital estimates. The items we review are listed below.

What we need

Site addresses or parcels, the audit or design date, the state, and site access if a roof walk is in scope.

First next step

Walter P Moore shares one current or recent pre-purchase audit; we return a sample file.

C

In-construction and new-build QA field inspections, nationwide

What Walter P Moore gets

Before/after documentation anywhere in the U.S.: a baseline at mobilization, a dated alert when a warning or a 0.75" radar band crosses an active site, photo-documented milestone checks, and a roof file at substantial completion. Routine field response flexes with distance from our home base and core group.

What we need

Active projects, site contacts, safety and access rules, and WPM’s QA checklist.

First next step

Walter P Moore names one active project for a pre-mobilization baseline.

D

Rapid mobilization and mitigation, nationwide (the headline offering)HEADLINE

What Walter P Moore gets

On site anywhere within 6 hours (Aaron Forsman’s commitment), in place from day one. Client buildings screened and ranked the same day, our team to the Strong buildings first, dated photo evidence for WPM’s engineers, and temporary protection by our affiliated trades company only where the client authorizes it.

What we need

An opt-in standing list of client addresses, escalation contacts, trigger thresholds, and who may authorize mitigation.

First next step

Agree the call-out path: who at Walter P Moore calls, who we call back; then a dry run on a past storm against five client addresses.

E

Scheduled maintenance and inspection agreements

What Walter P Moore gets

Recurring inspections plus an annual storm record, so each roof carries one continuous condition history into WPM’s capital plans. Modeled on our existing scheduled portfolios in central Minnesota farmland and the northern Twin Cities metro. A minimal per-square-foot fee, scaled to building size and technical difficulty, with terms set together.

What we need

Candidate multi-building clients (Jana’s health systems are the natural first fit), visit frequency, and report format.

First next step

Walter P Moore names one multi-campus client where condition continuity matters.

F

Ongoing AD CULMEN membership and access for WPM teams

What Walter P Moore gets

Named WPM users get exact-point records, portfolio screens and storm alerts on their own address lists, in the same format their engineers saw in the pilot. Volume-discounted, with terms set together.

What we need

Named users and groups (e.g. Diagnostics, Dallas and Kansas City), address lists, and data-handling terms.

First next step

After the day-14 pilot review, scope access for one named group.

Step B in detail

The due-diligence package: what we review, deliver and why it matters

ItemWhat we deliverWhy it matters
Exact-point storm historyFive years of NOAA radar hail size at the building’s own ~1 km cell and within 1 mile, with dates.Separates storms that crossed the roof from storms that only crossed the county.
Warned-day and hail-day countsNWS warning polygons over the point and two-source qualifying hail days, graded Strong / Moderate / Radar-only.Tells the buyer how often the site is actually hit, not just warned.
Open claim and filing windowsEach qualifying date with its statutory window and days remaining where the state is configured (Minnesota today; others per assignment).Shows which storm dates are still live before closing.
Permit and re-roof historyPublic roofing permits where published.Dates the current roof and flags work done after a storm.
Roof system conditionPhoto-documented, coordinate-tagged observations of the assembly, flashings, drainage and rooftop equipment; moisture scan where in scope.Gives the capital estimate a dated condition baseline.
Code and manufacturer-spec itemsDocumented observations of code- and installation-spec-relevant items (fastening, edge metal, coverboard, drainage) for WPM’s engineers to evaluate.Surfaces warranty and code questions early; the opinion stays with WPM.
Documentation standardSources on every line, a written method, and a provenance page.The file can stand as an exhibit and be checked by anyone.

We document weather, public records and observed conditions. Engineering, code and warranty conclusions stay with Walter P Moore.

The worked sample · AD CULMEN

Three buildings Walter P Moore already knows

Warnings covered these addresses on 123 days in five years. Hail reached the building on 9. That gap separates the storms that crossed a roof from the ones that only crossed the forecast.

Five hospital campuses (Des Moines, Sioux Falls, Minneapolis, St. Paul, Duluth): 139 warned days, 16 confirmed hail days at the building. Duluth: 17 warned, none confirmed.

Where we work

Nationwide, anchored where Walter P Moore has no office

Rapid mobilization anywhere within 6 hours. Routine field work flexes with distance from our home base and core group, which sit where Walter P Moore lists no office: Minnesota, Iowa and the Dakotas.
