Sun, wind, rain, and shifting temperatures can damage a roof gradually each year. Some of that damage stays hidden from the ground, such as cracked sealant or damp insulation in the attic. A professional roof inspection may reveal these conditions early.
The sections below cover what an inspector examines, what the written report contains, and how homeowners may use the results. They also describe a few signs inside the home that might suggest a roof problem.
How the Inspector Checks the Roof Surface
The inspector begins with the outer covering because it takes the full force of the weather. On an asphalt shingle roof, cracked, curled, or missing shingles draw the most attention. Bare patches may show where the protective granules, the small mineral particles on the surface, have deteriorated.
Wear is rarely even across a roof. A slope facing strong sun or wind may age faster than one in shade, so the inspector compares each side.
Tile roofs require checks for broken or shifted pieces, and metal roofs for loose panels and rust. Moss, algae, and standing water are recorded too, since they might show where moisture remains.
Checking Chimneys, Skylights, and Vent Pipes
At a chimney, the inspector checks the base, where masonry meets the roofing, for lifted metal or gaps. Skylight frames receive the same attention. Vent pipes are examined at the vent boot, the rubber collar that surrounds the pipe.
Rubber boots can crack as they age, and exposed nail heads may rust or loosen. Flashing, the metal strips that cover many of these joints, might lift at the edges. The inspector also checks the sealant along those edges for hardening or splits.
Gutters and Drainage in a Roof Inspection
Once water reaches the edge of the roof, gutters and downspouts carry it toward the ground. Sagging gutters, sections that have separated from the fascia (the board along the roof edge), and channels clogged with debris all appear in the inspector’s notes.
Downspouts that release water near the foundation are recorded as well. Overflow from a damaged gutter can reach the eaves and the lower edge of the roofing, and early repairs may cost less than fixing the damage that follows.
Inside the Attic Space
The inspector usually enters through a hatch in a hallway or closet ceiling. From there, the rafters, which are the sloped beams that support the roof, are visible. The roof deck, the wood layer beneath the roofing, is visible as well.
A roof inspection often includes this space because water damage may be easier to see from below. Dark rings on the wood, mold, or damp patches near a chimney or vent pipe may suggest a slow leak. Small points of daylight might indicate gaps.
Vents near the eaves and the peak allow air to circulate, so blocked vents or damp, flattened insulation may leave the attic hot and humid.
When Stains Appear After Rain
Timing can offer a useful clue. A ceiling stain that darkens or spreads after heavy rain may suggest a roof leak. A mark that appears in dry weather might come from plumbing or condensation, which is moisture that forms on cool surfaces.
Other indoor signs include bubbling paint, drywall that feels soft, and a musty smell in an upper room. Homeowners may notice these first in top-floor rooms or near exterior walls. Because several causes can produce similar marks, an inspection may help identify the true source.
What the Written Report Contains
After the visit, the homeowner receives a written report. Photographs often accompany the notes, so the homeowner can see each concern.
Urgent repairs, such as a cracked seal near a vent, usually appear separately from minor surface wear. Some reports add a maintenance plan, which homeowners may use to compare estimates from different contractors.
Making Informed Roofing Decisions
After reading the findings, a homeowner may want to ask which repairs need prompt attention, which can wait, and how long each repair might last. Homeward Roofing provides inspections and can answer questions about the process. To arrange an appointment, call (832) 899-4420.
