Quick Answer: A complete Calgary roof inspection report has six sections: executive summary, zone-by-zone findings with photos, severity rankings (immediate, short-term, monitor), recommended actions with cost ranges, estimated remaining lifespan, and maintenance recommendations. Read the severity ranking first; it tells you what to act on this week, what can wait a season, and what only needs monitoring.
A complete Calgary roof inspection report has six sections: executive summary, zone-by-zone findings with photos, severity rankings, recommended actions with cost ranges, estimated remaining lifespan, and any maintenance recommendations. The most important part for most homeowners is the severity ranking; it tells you what to act on this week, what can wait a season, and what just needs to be watched. The technical glossary below decodes the terms that show up most often in Calgary reports, and the priority-action framework gives you a structure for what to do once you know what the findings mean.
The quick orientation:
Read the severity ranking first. Immediate/short-term / monitor
Cross-reference photos to findings. Each item should have a photo
Check the remaining lifespan estimate. Plans your replacement timeline
Note the recommended actions. With cost ranges if included
File the full report. It is your documentation for the next inspection or any insurance event
This guide walks through each section, decodes the common terminology, and gives you the right follow-up questions to ask if anything is unclear.

The Six Sections of a Complete Report
1. Executive Summary
A one-page overview at the front. Includes inspection date, inspector name and credentials, address inspected, roof age and material, and a high-level summary of overall condition. If you only have 2 minutes, this is the section that gives you the headline.
2. Zone-by-Zone Findings
The body of the report. Findings are organized by roof zone (exterior surface, flashing, gutters, attic, ventilation, interior). Each finding should include: what was found, where on the roof, why it matters, and a photo.
3. Severity Rankings
Each finding gets a severity tag, typically immediate, short-term, or monitor. This is the section that drives your action list. A clean report has clear, consistent severity tagging across findings.
4. Recommended Actions
What the inspector recommends doing about each finding. Often paired with a rough cost range. Some inspection-only providers list recommendations without cost estimates; roofers who also do repairs typically include estimated ranges.
5. Estimated Remaining Lifespan
A dated estimate of how many years the roof has left in usable service, given its current condition. Useful for replacement planning and resale conversations.
6. Maintenance Recommendations
Routine items that are not urgent but extend roof life: gutter cleaning, sealant inspection schedules, ventilation adjustments, and annual or twice-yearly inspection cadence going forward.
Common Terms Decoded
The terminology in roof inspection reports is consistent across the industry. The 12 terms below cover most of what you will see.
Term | What it means |
Granule loss | Asphalt-shingle ceramic coating wearing off; advanced loss means end of life is near |
Bruising | Hail impact that crushed the shingle mat without breaking the surface; soft to the touch |
Cricket | A small ridge built behind a chimney to divert water; failure here is a common leak source |
Step flashing | Layered metal between shingles and a vertical wall (chimney, dormer); cracked sealant is a top leak source |
Counter flashing | The cap that overlaps the step flashing on a chimney |
Pipe boot | Rubber gasket sealing around plumbing stacks; UV-degraded boots are a leading source of older-roof leaks |
Ice and water shield | Self-sealing membrane installed at eaves and valleys; not visible but critical for ice-dam protection |
Underlayment | Felt or synthetic layer beneath shingles; second line of defence against water |
Soffit intake | Air intake under the eaves that ventilates the attic; blocked intake causes ice dams and shortens shingle life |
Net free area | Calculated open vent area for attic ventilation; should be roughly balanced intake-to-exhaust |
Deck delamination | Plywood or OSB layers are separating due to prolonged moisture |
Class 4 (impact rated) | Shingle category with the highest impact resistance; relevant in Calgary's hail zone |
If a report uses a term not on this list and is not clearly explained in context, ask your inspector. Reports should be readable by the homeowner who paid for them.
The Severity Tier Framework
Severity tags are the most useful part of the report for action planning. The standard tiers:
Immediate. Address within 30 days. Active leaks, structural concerns, safety risks, and exposed underlayment.
Short-term. Address within one season (3 months). Failing flashing sealant, missing shingles, and gutter issues affecting drainage.
Monitor. Track for the next inspection. Cosmetic granule loss, minor ridge cap wear, and vegetation that has not spread.
Some reports add a fourth tier (urgent or critical) for items requiring immediate same-week response. If your report uses different terminology, ask the inspector to translate; the underlying logic of "what should I do first" is what matters.
Building Your Action List
Once you have the report, the action list usually writes itself.
Step 1: Collect all immediate items. Schedule them in the next 30 days. If multiple items can be addressed by the same crew on the same visit, group them.
Step 2: Schedule short-term items by season. Items affecting drainage and ventilation typically wait for spring. Items affecting the roof surface condition typically wait for the fall. Match work to the right season unless the item is urgent.
Step 3: Add monitor items to your roof history file. They become reference points for the next inspection. If a monitor item progresses, it moves up to short-term.
Step 4: Compare to the estimated remaining lifespan. If the recommended repair spend is approaching 40 to 50 percent of the full replacement cost and the roof is past 20 years old, ask for a replacement vs. repair conversation before committing to repairs.
If a report finding is unclear or you want a second opinion, Angel's Roofing offers Calgary residential roof inspections with a written, photo-documented report you can compare. See the inspection service page.
Questions to Ask About Your Report
A 5-minute follow-up conversation with the inspector clears up most ambiguity. The most useful questions:
Which immediate items are the highest priority if I cannot do all of them at once?
Is any short-term item likely to become an immediate item before the next inspection?
What is your confidence level in the remaining lifespan estimate?
Are there cost-effective bundles (group repairs) that would save versus addressing items individually?
For any finding I do not understand, can you walk me through what is shown in the photo?
A reputable inspector or roofer will take this conversation as part of the service. If you get pushback, that is a signal about the company.
Frequently Asked Questions
Why are some findings rated "monitor" instead of "fix now"?
Not every finding requires action. A small area of moss on a north slope, minor surface granule loss on a roof with 10+ years of life left, or a single ridge cap with mild wear can be tracked rather than repaired. Monitor tags exist to keep the action list focused on what actually matters.
My report has no photos. Is that normal?
No. A complete inspection report should photograph each significant finding so you can see what the inspector saw. Verbal-only or photo-light reports are a quality issue. If your report lacks photos, ask whether they were taken and can be added.
The cost ranges in my report seem wide. Why?
Repair pricing depends on access, materials, season, and how many items are bundled together. A range of "$200 to $800" for a flashing repair often reflects whether it is a single-point repair or a multi-point repair on the same roof, plus any associated shingle work needed to complete the job. Ask for a firm quote on the specific work you plan to authorize.
What if my report and a second opinion disagree?
Reasonable disagreement on severity tiers is common; major disagreement on what was found is not. If two reports list different findings entirely, a third assessment from a credentialed inspector is reasonable, especially before any major work. Bring all three reports to the conversation.
How long should I keep my report?
Indefinitely. Roof inspection reports are part of your home's history file. They support warranty claims, insurance documentation, and resale conversations. Keep digital and paper copies. If you sell the home, the inspection history goes to the new owner as part of the documentation package.
My report says "remaining lifespan: 5 to 8 years." How precise is that?
It is an informed estimate, not a fixed prediction. Assumptions include normal weather years, no significant storm events, and continued reasonable maintenance. A bad hail year can shorten the estimate; a quiet weather period can extend it. Treat the range as a planning window, not a deadline.
