Roof inspection
An inspection is worth its cost when it answers a decision you are about to make: buying a house, planning next season’s budget, or deciding whether an aging covering has another few years in it. In a climate where a roof can read “dirty but fine” from the street and be brittle underneath, one documented look often tells you what the next five years will ask of you.
When it earns its price
Three moments justify the cost here. Before a purchase: a roof at the end of its life changes what a house is worth, and Piedmont streaking makes condition genuinely hard to judge from listing photos: the stains can hide a sound surface or a spent one.
After the summer, on an older covering: five months of heat do their damage invisibly, and fall is the least costly time to address what they left. And near the end of a covering’s expected life: when the real question is “this year or in three years,” a documented answer beats a guess in either direction.
What gets checked
On the surface: what actually sits under the streaking, because algae hides the granule surface it covers; the sun-side slopes, where age shows first; the edges, eaves, rakes, bottom courses, fascia, where Piedmont roofs actually end their lives; valleys under their straw load; sealant and flashing at every chimney, wall and vent penetration; and the rubber boots at plumbing vents, which crack in their second decade and are often a roof’s first true leak.
On the attic side, which a street-level look can never replace: ventilation: intake, exhaust, and whether twenty summers of builder-minimum airflow have been cooking the covering from below; moisture staining on the underside of the decking; bath fans ducted into the attic instead of outside; and daylight where there should be none. A report that skips the attic is half a report.
What the report is good for
A report earns its price the moment somebody else has to read it. Photographs and named locations let three contractors quote the same roof rather than three different impressions of it, and they give a buyer something concrete to put on the table. Dating the findings also puts the work on the calendar, which is worth real money in a market where the capable crews are committed by early spring.
What a Piedmont inspection actually looks at
- What does the inspector look for in the valleys under pines?
- The mat. Pine straw packs into the valley, holds water against the covering, and hides the metal underneath. The report should say whether the valley is open metal or closed, whether the mat has been cleared, and whether the shingle under it is still holding its granules.
- Are the black streaks a finding, or just cosmetic?
- Both, in order. The streaks are algae and they start as a cosmetic issue on the shaded slope; what the inspector checks is the granule condition under them, because a streaked slope that has also gone bare is a different conversation.
- Why does the inspection include the attic in a climate with barely any winter?
- Because the attic is the oven. NOAA puts Charlotte and Raleigh at roughly sixty days a year at or above ninety degrees over the last decade, and an attic that cannot exhaust cooks the covering from below. The intake and exhaust balance is a finding, not a footnote.
- When should a house built around 2005 get its first inspection?
- When the street starts turning. A phase built in two years reaches its first replacement in a narrow window, and the first few jobs on the block are the signal. An inspection then tells you whether you are ahead of the wave or in it.
- What actually fails a roof inspection out here?
- Granule loss confirmed under the algae staining, cracked vent boots, valley metal that has corroded under a pine straw mat, and flashing that was caulked instead of rebuilt at a chimney or wall. A roof can look dirty rather than damaged from the driveway and still fail on one of these findings once the surface is actually examined.
- Why do I keep getting calls about roof inspections?
- Most of those calls trace back to a purchased address list rather than to anything anyone has actually seen on your roof, and they tend to spike after any stretch of severe weather passes through the Piedmont. A real inspection is one scheduled for a reason you can name, and it produces a written report with photographs, not a same-visit sales pitch.
- 1 Ridge caps. Thin, hot, and the first course to loosen on a Piedmont summer roof.
- 2 The field. Streaks first, then real age. The two are not the same problem.
- 3 Valleys. Pine straw mats where two slopes drain as one, and holds the water there.
- 4 Flashing. The chimney, and the line where the garage roof meets the wall.
- 5 The vent boot. Usually cracked by its teens, long before the field around it is.
- 6 Eaves. Where gutter overflow lands, and where the fascia goes soft first.
