What’s included

What a roof inspector examines

A thorough inspection covers every component of your roof system — not just the shingles. Here’s what a qualified contractor or inspector looks at.

Shingles and surface
The condition of the surface material is the primary focus — both visible damage and signs of hidden wear.
  • Granule loss and accumulation in gutters
  • Cracking, curling, cupping, or blistering
  • Missing or displaced shingles
  • Hail impact marks (bruising)
  • Algae or moss growth
Flashing and penetrations
Flashing seals the transitions between your roof and any structure that penetrates it — chimneys, vents, skylights, walls.
  • Chimney flashing condition and seal
  • Vent pipe collars and boots
  • Valley flashing integrity
  • Skylight seals
  • Step flashing at walls and dormers
Gutters and drainage
Gutters are part of your roof system — poor drainage causes water to back up under shingles and damage fascia.
  • Gutter slope and alignment
  • Denting or damage from hail
  • Granule accumulation (sign of shingle wear)
  • Downspout condition and clearance
  • Gutter guard or screen condition
Ventilation
Roof ventilation regulates attic temperature and moisture — critical for shingle longevity and energy efficiency in Colorado’s climate.
  • Ridge vent condition and clearance
  • Soffit vent blockage
  • Attic ventilation balance
  • Signs of heat or moisture damage from below
Decking structure
The decking — typically OSB or plywood — is what your shingles are fastened to. Hidden rot or water intrusion here means a more extensive repair scope.
  • Soft spots or spongy areas (sign of rot)
  • Visible sagging or deformation
  • Signs of past or active water intrusion
Interior attic inspection
A thorough inspection includes a look from inside the attic — stains, daylight gaps, and moisture are often visible before damage is apparent from the exterior.
  • Water staining on rafters or decking
  • Daylight visible through the deck
  • Mold or moisture accumulation
  • Insulation condition
Which type is right for you

Free vs. paid roof inspections

Both are legitimate. The difference is who performs them and what you’re trying to accomplish.

Free inspection
From a licensed roofing contractor

Free inspections from licensed contractors are standard practice in the Denver market — particularly after storm events. A contractor inspects, identifies any damage, and provides a written assessment and estimate if repairs are warranted.

This is not a bait-and-switch. Contractors offer free inspections because it’s their primary method of generating work, and because homeowners have no realistic way to assess roof damage themselves.

The key is using a vetted, licensed local contractor — not someone who appeared door-to-door the morning after a storm.

Best for: storm damage assessment, annual check-up, pre-claim documentation
Paid inspection
From an independent inspector

Independent roof inspectors — often certified through NRCIA or similar bodies — provide an unbiased third-party assessment. They have no financial stake in whether repairs are done or what scope is recommended.

Paid inspections typically run $150–$400 in Denver. They’re most useful in situations where you need truly independent documentation: a home purchase with a roof of uncertain age, a dispute with an insurer, or a situation where you don’t trust the contractor’s assessment.

For post-storm damage assessment, a free inspection from a vetted contractor is typically sufficient. The independent inspection is a tool for specific situations, not a requirement.

Best for: home purchase, insurer disputes, second opinions
Five situations that require action

When should Denver homeowners get an inspection?

Most homeowners only think about their roof when something goes wrong. These are the moments when a proactive inspection protects you.

  1. 1
    After any hail or wind event — even without visible damage
    Hail damage to asphalt shingles is not always visible from the ground. Impact bruising can compromise a shingle’s structural integrity without leaving an obvious mark. The only way to know is an inspection. In Denver, significant hail events occur every few years and minor events happen annually. Have your roof inspected after any storm that leaves dents in your car, gutters, or downspouts.
    Act within 30 days — insurance claim windows and contractor availability both close.
  2. 2
    Before buying or selling a home
    A standard home inspection includes a visual look at the roof, but most home inspectors are generalists — they identify obvious issues, not subtle hail damage or granule loss patterns. A dedicated roof inspection before purchase gives you accurate information about remaining useful life and any deferred repairs that should affect your offer or your negotiation.
  3. 3
    If your roof is 10 or more years old and has never been inspected
    Asphalt shingles in Colorado typically have a functional lifespan of 20–25 years, but Denver’s UV intensity, temperature cycling, and hail exposure accelerate wear. A roof approaching 10–15 years deserves an inspection to establish its current condition and remaining life — before it becomes an emergency repair.
  4. 4
    After noticing interior water stains or ceiling damage
    Interior water stains are a signal that water is penetrating the roof system — but they rarely tell you where the breach is. A roof inspection identifies the entry point before the damage spreads. Don’t patch the ceiling and wait. Find the source.
    Interior moisture typically indicates an active problem — don’t delay.
  5. 5
    Before filing an insurance claim — document first
    If you suspect storm damage, get an inspection and written assessment before you open a claim. The inspection report creates a dated record of the damage, which is valuable if your insurer disputes the scope or attempts to attribute damage to pre-existing wear. Documentation created before a claim is filed carries more weight than documentation created after.

What comes next

What happens after an inspection?

An inspection always ends with a written assessment. What happens next depends on what the inspector found.

If damage is found
You receive a scope and recommendation

Your contractor provides a written scope of the damage, a recommendation for repair or replacement, and a cost estimate. For insurance-covered events, they can document the damage in the format adjusters expect and be present for your adjuster’s visit.

You are not obligated to proceed with the same contractor who inspected. The inspection report is yours regardless of what you decide next.

If no damage is found
You receive documentation for your records

A clean inspection report is not a wasted trip. It creates a dated record of your roof’s condition — useful for insurance purposes, future sale, and your own maintenance planning.

A contractor may note areas of potential concern or recommended maintenance even when no immediate repair is needed. That information helps you plan rather than react.

Denver-specific timing

Why timing matters more in Denver than most markets

Denver’s hail season runs from approximately May through September, with peak activity in June and July. The Front Range sees more hail events per year than most of the country — and the severe storms that cause insurance-grade damage follow an unpredictable but consistent pattern.

After a significant event, three things happen simultaneously: homeowners discover damage, insurers begin managing a surge in claims, and contractor demand spikes across the metro. Inspection appointments book out. Permit processing slows. Contractor scheduling extends by weeks.

The homeowners who fare best are the ones who get an inspection scheduled in the days immediately following a storm — not after weeks of researching their options.

Most Colorado insurance policies require claims within one year of the date of loss. Don’t wait until the following spring to have a storm from last July inspected. Document it now — even if you’re unsure whether to file.
Common questions

Denver homeowners ask

A typical residential roof inspection takes 45 minutes to 2 hours depending on the size of the home, roof complexity, and whether an attic inspection is included. After the inspection, a written report or assessment is typically provided same-day or within 24–48 hours.

For an exterior inspection only, your presence isn’t strictly required — though it’s recommended so you can ask questions and receive the assessment in person. If an attic inspection is included, someone needs to provide access to the interior. Being present also gives you the opportunity to document anything the inspector identifies, which is valuable for insurance purposes.

General recommendation is every 3–5 years for a roof in good condition, and after any significant storm event. In Denver’s hail corridor, after a major storm is the trigger most homeowners should prioritize — weather events create more roofing claims than age alone.

An inspection assesses the condition of your roof and identifies any damage or wear. An estimate follows from the inspection — it specifies what work is recommended and what it will cost. Many contractors combine both into a single visit: they inspect, then provide a written assessment and estimate. If no damage is found, no estimate is needed — that’s a good outcome, not a wasted trip.

Getting an inspection does not affect your insurance — it’s a private assessment between you and a contractor. Only opening a formal claim with your insurer affects your claims history. However, an inspection report is valuable evidence if you do file a claim: it documents the condition of your roof at a specific point in time, which can help establish that damage was caused by a specific storm event rather than pre-existing wear.
