Quick Answer
A professional roof inspection covers four areas: the exterior surface (shingles, flashing, valleys, penetrations, gutters), the structure (rooflines, soffit and fascia), the attic interior (ventilation, moisture, daylight, insulation), and documentation (a written report with photos). It typically takes 45–60 minutes and ends with a clear assessment of your roof’s condition and remaining life.
Johnny Wudel and the Olympus Roofing team have inspected Wasatch Front roofs since 1973. Owner Cason Curriden holds Utah DOPL license #6402827-5501, plus GAF Master Elite and Owens Corning Preferred Contractor certifications, so the guidance here reflects real Utah jobs, not national averages.
What Does a Professional Roof Inspection Include?
A professional roof inspection is a systematic, four-part review of your entire roof system — not just a glance at the shingles. A qualified inspector evaluates the exterior surface, the supporting structure, the attic interior, and then documents everything in writing with photos. In Olympus Roofing’s inspection records since 1973, the problems that matter most often hide where homeowners can’t see them: under flashing, inside valleys, and in the attic. That is why a real inspection goes far beyond a visual drive-by. If you’re not sure how often to schedule one, see our guide to how often you should inspect a roof in Utah, and if you already suspect trouble, our list of signs you need a new roof tells you what to watch for.
What Gets Checked on the Roof Surface?
The exterior surface inspection is the most visible part and where storm and age damage usually shows first. The inspector walks the roof (when safe) to examine shingles for granule loss, curling, cracking, and missing tabs, then checks the components that actually keep water out: flashing around chimneys and walls, valleys where slopes meet, and penetrations like vents, pipes, and skylights. Gutters and downspouts are checked for granule accumulation — a reliable sign of shingle wear. Flashing and penetration failures, not the shingle field, are the leak sources we find most often, which is why a thorough surface check matters more than shingle age alone.
What Does the Inspector Look for in the Attic?
The attic is where an inspection separates the professionals from the amateurs. From inside, the inspector evaluates ventilation balance, looks for moisture stains, mold, and rot on the underside of the deck, checks for daylight showing through the roof boards, and assesses insulation. The U.S. Department of Energy’s Energy Saver guidance treats attic ventilation and insulation as central to a roof’s health and energy performance. Many roofs that look fine from the street are failing from below because of trapped heat or moisture. Skipping the attic means missing the single most common cause of premature roof failure we document in Utah.
How Does a Roof Inspection Work, Step by Step?
A professional roof inspection follows a repeatable process so nothing gets missed. Here is the sequence Olympus Roofing uses on a standard residential inspection — the same process behind every free roof inspection we offer:
- Schedule and review history — confirm the roof’s age, material, and any past repairs or leaks before arriving.
- Inspect the exterior surface — examine shingles, flashing, valleys, penetrations, and sealants for wear and storm damage.
- Check the structure and rooflines — look for sagging, uneven planes, and the condition of soffit and fascia.
- Inspect the attic interior — assess ventilation, moisture, mold, daylight through the deck, and insulation.
- Evaluate gutters and drainage — check for granule loss, blockages, and proper water flow away from the home.
- Document findings — capture photos of every issue and note severity and location.
- Deliver a written report — provide a clear assessment, remaining-life estimate, and prioritized recommendations.
What’s in a Complete Roof Inspection Checklist?
A complete inspection covers every system that keeps water out and the roof structurally sound. The table below shows what a full Olympus inspection checks and why each item matters.
| Area | What We Check | Why It Matters |
|---|---|---|
| Exterior surface | Shingles, granule loss, flashing, valleys, penetrations, sealants | These are the first and most common leak points |
| Structure | Rooflines, sagging, soffit and fascia condition | Reveals framing or moisture damage and intake-vent health |
| Attic interior | Ventilation, moisture, mold, daylight through deck, insulation | Catches hidden failure and the top cause of early roof death |
| Drainage | Gutters, downspouts, granule buildup, water flow | Backed-up water rots fascia and shortens edge shingle life |
| Documentation | Written report, photos, remaining-life estimate | Gives you proof, a plan, and leverage for insurance or sale |

How Long Does a Roof Inspection Take and What Does It Cost?
A standard residential roof inspection takes about 45–60 minutes, depending on roof size, pitch, and complexity. Cost depends on whether it’s free or paid. Many Utah roofers, including Olympus, offer free inspections for homeowners considering repair or replacement, or after a storm. Paid inspections — typically $150–$400 in Utah — are usually for real-estate transactions, insurance documentation, or formal certifications where an independent, fee-based report is required. Either way, hire a licensed contractor; you can verify any Utah roofer’s license through Utah DOPL. A licensed, insured inspector protects you if something goes wrong on your roof.
What Do You Receive After the Inspection?
After the inspection, you should receive a written report with photos, a condition assessment, and a prioritized list of recommendations. The report documents what was found, where, and how urgent each issue is, plus an estimate of your roof’s remaining life. This documentation is valuable well beyond the inspection itself — it supports insurance claims, informs home sales, and gives you a clear maintenance roadmap. A verbal “looks fine” is not an inspection. If a contractor won’t put findings in writing with photos, that’s a sign to get a second opinion before any work begins.
Frequently Asked Questions
How long does a roof inspection take?
A standard residential roof inspection takes about 45–60 minutes. Larger, steeper, or more complex roofs take longer, and adding an attic moisture and ventilation review extends the time. The visit ends with a clear assessment of your roof’s condition. A thorough inspection should never feel rushed — if someone is done in five minutes, they likely skipped the attic and flashing.
How much does a roof inspection cost in Utah?
Many Utah roofers, including Olympus Roofing, offer free inspections for homeowners weighing repair or replacement or recovering from a storm. Paid inspections typically run $150–$400 and are used for real-estate sales, insurance documentation, or formal certifications that require an independent, fee-based report. Which one you need depends on the purpose, not the roof itself.
Are free roof inspections legit?
Yes, when done by a licensed, reputable contractor. A free inspection is a standard, no-pressure way for a roofer to assess your roof and earn potential repair or replacement work. The key is to verify the contractor’s license through Utah DOPL and insist on a written report with photos. Avoid anyone who pressures you to sign immediately or invents damage.
Do I need to be home for a roof inspection?
For the exterior surface inspection, no — the inspector works on the roof and grounds. But for a complete inspection that includes the attic, someone needs to provide interior access. Since the attic reveals ventilation and moisture problems that the surface hides, being home for at least part of the visit is worth it for a full picture.
What report do I get after a roof inspection?
You should receive a written report that includes photos of any issues, a condition assessment, severity ratings, an estimate of remaining roof life, and prioritized recommendations. This documentation supports insurance claims, home sales, and maintenance planning. A reputable contractor always puts findings in writing — a verbal summary alone is not a professional inspection.
How often should I have my roof inspected?
In Utah, twice a year is ideal — once in spring after winter freeze-thaw and once in fall before snow arrives — plus an extra inspection after any major hail or windstorm. Roofs over 15 years old benefit from more frequent checks. Regular inspections catch small failures before they cascade into deck or interior damage.
Will an inspection damage my roof?
No. A professional inspector walks the roof carefully, using proper footwear and technique to avoid disturbing shingles, and inspects from a ladder or with magnification where walking would risk damage. On very steep, fragile, or snow-covered roofs, inspectors may use drones or binoculars. A trained inspector knows where to step and how to move without harming the roof.
Do I need an inspection to file an insurance claim?
Usually, yes. Most insurers want documented evidence of damage, and a professional inspection report with dated photos provides exactly that. Having an independent, licensed contractor document the damage strengthens your claim and helps ensure the scope of repair is accurate. We recommend an inspection before filing, so you know what you’re claiming and can support it.
