A Clean Roof Report Still Lists Every Area It Checked
A report with no defects should still name each slope, flashing, vent and attic space the inspector looked at, and say what could not be seen.
A roof inspection that finds nothing wrong still produces a document, and that document should look different from a one-line verdict. If the report says only that the roof is fine, the homeowner has no record of what was looked at, and the next visit starts from zero. This page is for the moment the report is in hand, the inspector has said nothing is failing, and the question is whether that answer can be relied on.
Inspection
A usable clean report names areas. It should list each roof slope separately, with the material on it, the approximate age the inspector observed or was told, and the condition of the surface. It should list every penetration: plumbing vent boots, exhaust vents, the furnace flue, a bath fan cap, and any skylight or chimney. It should also name the flashing at walls, the valleys, the drip edge at the eaves and rakes, and the ridge. A line that reads "no defects observed" tells you the inspector was on the property. It does not tell you which parts were walked, which were viewed from a ladder at the eave, and which were seen only from the yard.
Ask for the walk to be written as a sequence of stops. A clean report from a walk that started at the north slope and ended at the garage roof is different from one that skipped the low section over the porch. The order matters less than coverage, but a numbered list of stops makes a missing stop easy to see, and it gives the next inspector the same starting point.
The slopes, one at a time
Each slope in St. Louis takes weather differently. A south or west face gets more sun and more daily heating and cooling, so its surface can look worn sooner. A north face stays damp longer after rain and after a freeze, and dark streaking or moss tends to start there. An east face takes the morning sun and the morning frost first. A report that treats the whole roof as one surface gives less information than it seems to.
Check whether the report gives a condition for each slope in plain words. A sentence such as granule loss along the lower courses on the southwest slope, with no exposed mat, is usable. The word good by itself is not. If the report says the surface is intact, it should also say whether any shingles were lifted to look at the nail line and the sealant strip. Many surface inspections look only at the top of the shingle, and that can be a legitimate scope, but the report should state it.
Pay attention to the shingle type named on each slope. A report that describes one slope with a dimensional profile and another with a three-tab profile has told you the roof was not replaced all at once. That matters for repair planning, because a patch that matches one slope may not match the next, and a repair that needs a discontinued profile can change the scope of the work.
Flashings and penetrations
Many leaks in this area do not start in the middle of a field of shingles. They start at a joint: the pipe boot where a rubber collar has split, the step flashing where a wall meets a slope, the counterflashing at a chimney, or the valley where two slopes drain together. A clean report should say each of these was checked, not only that the roof shows no leaks. If there is a chimney, the report should describe the crown and the flashing separately, since the crown is masonry and the flashing is metal, and one general word covers neither well.
Ask whether the inspector looked at each pipe boot collar from the roof or from a ladder at the eave. From the eave, a cracked collar on a vent near the ridge is often out of view. Neither method is wrong on its own, but the report should say which one was used for each penetration, so any gap in coverage is visible on paper.
The attic side
An attic check shows what the roof has been doing over time. Staining on the underside of the deck, darkened nail tips, or a faint tide line along a rafter can mark a leak that has since dried. A report that says attic accessed, no staining should also say which attic was entered, because many houses have more than one space under the roof. It should say whether the inspector reached areas above a finished ceiling or only the open hatch area. The hatch is part of the roof inspection, but a clean hatch does not cover a bonus room tucked under a low slope.
Look for ventilation and insulation in the same report. A roof surface can be sound while the attic runs hot in summer and frosts in winter. In a cold stretch, warm moist air from the house that reaches a cold deck will condense and can freeze, so the report should say whether the ridge vent, the soffit intake, or both were seen, and whether they appeared open. A clean surface does not prove the attic is ventilated.
Gutters, eaves and the freeze
The freeze and thaw cycle in St. Louis gives a roof a hard year. Water gets under a lifted shingle, freezes, and widens the gap a little more each time. Ice at the eave can push meltwater back under the shingles, which is the ice dam problem that shows up as stains on ceilings near an exterior wall. A clean report should say whether the eave was checked for ice dam signs, for frost on the underside of the eave deck in winter, and whether the gutters drain clear to the downspouts.
Gutters full of leaves are not a roof defect, but a report that ignores them has skipped the part of the house where water leaves. If the inspection happens in late autumn, the report should also say so. Shingles that look sound when dry can crack when cold, and an inspection on a wet day may miss a seam that a dry one would show. A report written under those conditions should list what could not be seen.
Hail and the record
Hail season in the metro runs through spring and early summer, so a fall inspection is usually a check on wear rather than on a fresh storm. A clean report should still say whether the inspector looked for hail marks on the soft metal, such as gutters, downspouts, vent hoods and the ridge cap, even when the answer is no. If the house has been through a storm, the report should name the date the homeowner gave and label it as the homeowner's date. A date supplied by the homeowner is information, not a finding, and the report should keep the two apart.
Photos and measurements
Photos turn a clean sentence into a record. Each slope should have at least one photo that shows the whole plane and one that shows the surface up close, and each penetration should have its own photo with the flashing visible. Photos should carry a date and should be sent as original files, not screenshots, so the detail survives. The text of the report should refer to the photos by slope and stop, so each sentence can be matched to an image.
Measurements belong in the report too. A roof area figure, the pitch of each slope, and the length of the eave and rake lines let a second contractor check the numbers without climbing the roof. If the report gives an area but no pitch, ask why. Pitch affects which installation methods are safe and how the crew reaches the work, so a steep slope may need a different plan on the day.
What it costs
The inspection visit is not always a line on the report, and its cost is not always stated in the same place as the findings. Ask for the visit cost in writing before the appointment, and ask whether a second trip is needed if the first one could not reach a slope. A visit that stops at the ladder for safety reasons is a different service from a visit that walks every stop, and the report should say which one happened.
What to ask when the report says nothing is wrong
Take the report up to the house, read it slope by slope, and check each line against what is actually there.
- Which slopes were walked on the roof, and which were viewed from the ground or a ladder?
- Were the pipe boots, the chimney flashing and the valleys checked by hand, or only from the eave?
- Which attic spaces were entered, and was the bonus room or any low section above a porch reached?
- Does the report name the material and the approximate age of each slope?
- Are the photos attached and dated, and do they match the slopes and stops named in the text?
- What could not be seen, and what would have to be lifted or opened to see it?
