An inspection report is only worth the decisions it lets you make. We walk the roof, cut the cores, take the photographs and hand you a document that sorts what needs attention this month from what can wait for next year's budget. Each finding carries a location, a photo and a price range. You can forward it to a lender, an insurer or a board without rewriting a word.
In Coeur d'Alene, ID the winters do the sorting for you. A roof that carries a 60 psf ground snow load on the city design sheet gets tested every year, so we inspect it with that test in mind.
On the Roof: What We Touch
We walk the field and put hands on the details. We probe seams, press on flashings, check sealant beads, look for ridges over fasteners and measure how far drains sit below the membrane. We note ponding, check for blisters and look at how the membrane meets walls, curbs and pipes. Edge metal gets checked for fastener spacing, joint gaps and sealant condition.
Then we look at what sits on the roof. Rooftop units, conduit and cable trays can scuff membranes, block drainage and trap debris. Mechanical contractors who visit a roof for filter changes leave marks, and we record them. The walk takes longer than a drive-by, and the report shows the difference.
Core Cuts: Looking Under the Membrane
What you see on the surface is half the story. The other half sits in the layers underneath. We cut small cores at selected spots, check the insulation for moisture, measure thickness, identify the layers and check the deck underneath. Each core is patched the same day with materials matched to the roof.
Cores answer the budget question: how much life is left? A dry assembly with a worn surface may last years. A wet one may be past saving even if it looks clean. For larger roofs, we pair the cores with an infrared moisture survey so the cores confirm a map instead of guessing at one.
The Report: Findings, Photos, Prices
The written report lists findings in order of urgency. For each one you get a plain description, a photograph, a location on a roof sketch and a price range for the fix. Items are grouped as repair now, repair this year, monitor, and plan for replacement. Nothing in the report is written to scare you into a contract.
The report also gives a remaining service-life estimate and a recommended path: maintain, repair, recover or replace. Owners with several buildings can feed those results into a roof condition report format that compares sites on one scale. That comparison is what turns a stack of inspections into a capital plan, and it lets a board or an asset manager rank buildings by risk instead of by who complained last.
Snow Season: Inspect Before and After
The best time to inspect is before the first storm and again after the thaw. The fall visit catches loose flashings, clogged drains and open seams before snow can load them. The spring visit finds what winter did. Coeur d'Alene averages about 25.4 inches of precipitation a year, and the snow that melts and refreezes shows its damage at seams and low points.
The city's own guidance says saturated snow weighs roughly 20 pounds per cubic foot. In spring we look for deck deflection near drains, cracked membrane at drift lines and displaced rooftop equipment. Those are the marks a heavy winter leaves, and they are cheaper to deal with in April than in August. Catching a displaced curb or a split seam in spring also gives us time to fit the repair into a dry stretch before summer scheduling fills up.
Building Types: What We Look For Where
A tilt-up warehouse like those in Riverbend Commerce Park in Post Falls has long, flat roofs with perimeter parapets, so we pay attention to scuppers, parapet flashings and drainage. A school roof, such as the buildings of the Coeur d'Alene School District, the county's second-largest employer, often has many small roof areas at different heights, and each gets its own findings.
Medical and office buildings have rooftop equipment and tight interiors, so curbs and penetrations get extra scrutiny. In Hayden, which had 15,570 residents in 2020, and across a county of 171,362 residents, the inspection starts from what is actually on the roof, not from an assumption about the neighborhood or the building's age.
Records: Warranties, Code and Paperwork
We ask for the roof drawings, past repair invoices and any warranty documents before the walk. Those records help us match the findings to what was installed and to what the warranty requires. Missing records are not a problem. We record what we find, note what we could not confirm and flag which unknowns are worth a follow-up core or a call to the original installer.
Idaho enforces the 2018 International Building Code, and a replacement or large repair triggers current requirements. Where the inspection points toward replacement, the report notes the code items that will affect the scope, so the budget includes them. For a purchase or a refinance, the same visit can be run as one of our due diligence roof surveys.
Access and Safety: Reaching Every Corner
Some roofs are hard to walk: steep transitions, fragile skylights, high parapets, or areas fenced off around equipment. For those, a drone roof inspection gives a clean overview before anyone steps on the membrane, and it shows ponding, staining and debris patterns that are hard to read from the surface. The drone supports the walk. It does not replace probing and cores.
We follow fall-protection rules on every visit, tie off at open edges and avoid walking on skylights and skylight domes. If a roof is not safe to walk, we tell you that in the report and recommend the repair that makes it safe, because an inspection that cannot reach a detail cannot clear it.
Commercial Roofing Questions
How long does an inspection take on a large roof?
A typical commercial roof takes a few hours on site, with more time for very large or complex roofs. The report follows within days. Core cuts and infrared work add time, but they are what makes the report defensible.
What should I have ready before the visit?
Roof access, drawings if you have them, warranty papers and a list of known leaks. If tenants have reported problems, bring those dates. The more history you share, the sharper the findings.
Will an inspection void my warranty?
No. Core cuts are patched to match the roof, and the work is documented. If your warranty has inspection requirements, we can do the visit to meet them and keep the report for the file.
Can the report be used for a sale or a loan?
Yes, and it is written for that audience. The findings are specific, the photos are labeled and the cost ranges are explained. Lenders and buyers get clear answers on condition and remaining life.
Do you inspect in winter?
We inspect when the roof is safe to walk. Snow and ice limit what we can see and probe, so we may do an interior review and a limited exterior visit, then return after the thaw for the full survey.
What if the report says the roof is fine?
Then you have a clean baseline, which is worth having. We note what to watch and when to check again, so the next inspection starts from known conditions.
