Report writing craft
Attic and insulation narratives, findings from the space nobody visits
Insulation depth, ventilation, moisture signals, and exhaust terminations. Attic narratives that turn an awkward crawl into the report's quiet value section.

Nobody buys a house for its attic, and no space in the house predicts more expensive problems earlier. Moisture from below, leaks from above, ventilation failures cooking the roof from inside, all of it shows in the attic first, which makes the section a quiet showcase for the inspector who reports it precisely. The three-part structure does the carrying, and the attic adds one discipline of its own, naming your vantage.
The vantage sentence, first and always
Attic access varies from walkable decking to a head-and-shoulders look from the hatch, and your findings inherit their credibility from saying which. The attic was inspected from the access hatch and adjacent decked areas. Portions beyond the decking were observed from that vantage and not traversed.
Two sentences, and every finding after them is properly framed. The liability inventory files undocumented limitations under expensive silences, and the attic is where that filing happens most, because insulation hides what you cannot walk to and everyone later assumes you saw everything.
Insulation, measured and translated
Depth and coverage, the baseline finding. Blown insulation was observed at an approximate depth of six inches across accessible areas. This depth is below current recommendations for this climate region. Recommend adding insulation for improved efficiency and comfort. Approximate depth, observed areas, current recommendations, three precision markers in two sentences, and a recommendation framed as improvement rather than deficiency, which is the honest calibration for an efficiency finding in an older house.
Uneven coverage. Insulation coverage was uneven, with bare and thin areas observed near the eaves and around the attic access. Gaps in coverage reduce effectiveness and can create cold spots at ceilings below. Recommend redistributing or supplementing insulation at the affected areas.
Compressed or disturbed insulation, the trades' footprints. Insulation was compressed and displaced along apparent service paths to the HVAC equipment. Compressed insulation loses effective value. Recommend fluffing or supplementing along the affected paths after any service work concludes.
The missing hatch treatment. The attic access hatch was uninsulated and lacked weatherstripping. An unsealed hatch is a significant bypass in the ceiling's thermal boundary. Recommend insulating and sealing the hatch. Small finding, cheap fix, real effect, exactly the kind of entry that makes reports useful rather than just thorough.
Ventilation, the slow cooker findings
Blocked intake. Soffit vents were obscured by insulation at multiple bays along the north eave. Blocked intake ventilation restricts airflow through the attic assembly. Recommend installing baffles and clearing the soffit openings.
Inadequate exhaust, reported through its symptoms. Limited exhaust ventilation was observed relative to the attic's area, and elevated heat was notable at the time of inspection. Restricted ventilation shortens shingle life and promotes condensation in cold seasons. Recommend evaluation of the ventilation balance by a qualified contractor. The consequence sentence connects the attic to the roof covering's lifespan, the coupling that turns two sections into one system.
Signs the ventilation already lost. Darkened sheathing and surface frost staining were observed at the north roof deck. These conditions are consistent with recurring condensation. Recommend correcting ventilation and moisture sources, and evaluation of the sheathing by a qualified contractor.
Moisture and the exhaust that causes it
The classic finding, worth its own precision. A bathroom exhaust duct terminates in the attic rather than at the exterior. Moist air discharged into the attic assembly promotes condensation and can degrade framing and sheathing. Recommend extending the duct to a proper exterior termination. This narrative appears in the worked examples because it is that common, a two-hundred-dollar fix preventing a five-figure sheathing job, invisible from inside the house.
Stains from above. Staining was observed on the roof sheathing below the chimney penetration, dry at the time of inspection. Staining at penetrations is consistent with past moisture entry at the flashing above. Recommend evaluation at the roof level and monitoring. Dry today, time-stamped, and pointed upward toward its cause, the same coupled honesty the plumbing section uses for ceiling stains.
Wildlife and the unwelcome tenants
Attics collect evidence of occupancy, and the narrative treats it as condition, not comedy. Droppings consistent with rodent activity were observed along the north eave, with disturbed insulation in the same area. Rodent activity degrades insulation and can damage wiring. Recommend evaluation by a pest control professional and repair of affected insulation. When entry points show, name them, daylight was visible at a gap in the soffit near the same location, recommend sealing after remediation. The coupling of evidence, consequence, and entry point turns an unpleasant find into a complete, actionable finding.
Structure glimpses and the photo habit
The attic offers the house's only open look at roof framing, and one affirmative line banks it. Visible roof framing appeared serviceable from the vantage described, with no sagging, fracture, or modification observed. When modifications do show, cut trusses are the finding that escalates, a truss member near the access appeared cut and unrepaired. Modified trusses can compromise the roof structure. Recommend evaluation by a structural engineer.
Photos in the attic need the light you brought, so shoot wide with the flash for context, close on the condition, and put the annotation circle to work, since dark-space photos read as noise without it. A location anchor in frame, the hatch, the chimney, a duct run, saves every attic photo from the which-corner-was-this problem.
Load the set into your library, and the section that costs the most sweat per finding starts paying the most information per minute, written before you ever climb the ladder.
Common questions
How precise should insulation depth reporting be?
Approximate observed depth and the resulting coverage judgment, measured where accessible. An approximate depth of six inches was observed reads as measurement. Feels thin reads as mood. Precision is a tape measure and one sentence.
What if I can only inspect from the hatch?
Then the report says so, observed from the access hatch, and every finding carries that frame. Documented vantage is professional scope. Undocumented vantage is a claim you inspected what you saw from a ladder.
Are attic findings really worth the crawl?
The attic is where roof leaks announce themselves early, where ventilation problems cook shingles, and where bathroom fans quietly rot sheathing. It is the highest information-per-minute space in the house, which is exactly why the narratives deserve pre-built language.
