When most homeowners think about a roof inspection, they picture someone walking around the yard and glancing up. A professional inspection is a different thing entirely. Done right, it’s a methodical examination of every component that makes up your roofing system — from the surface shingles down to the attic below.
Here’s what Divided Sky’s inspectors look at, and why each element matters.
The Roof Surface
The surface is the starting point, but it’s not a simple visual pass. Inspectors examine:
- Shingle condition. Granule loss, cracking, curling, cupping, blistering, and missing shingles. Each failure mode tells a different story about age, installation quality, or storm damage.
- Hail impact patterns. Hail damage often appears as random circular spots of granule loss. An experienced inspector can distinguish storm damage from other causes of granule loss.
- Wind damage. Lifted shingle edges, broken seal strips, and missing shingles in patterns consistent with high-wind events.
- Surface aging. The overall condition of the field shingles relative to their estimated age — are they aging normally, or faster than expected?
Flashing at All Penetrations
Flashing is the metal material that seals the gaps where the roof meets other structures: chimneys, skylights, vent pipes, HVAC curbs, and wall-to-roof junctions. It’s one of the most common sources of roof leaks and one of the most overlooked areas in basic visual inspections.
The inspector checks for:
- Separation or gaps between the flashing and the adjacent surface
- Corrosion or rust on older metal flashing
- Failed sealant or caulking
- Improper installation where water can channel behind the flashing
Flashing failures often develop slowly over years. You won’t notice them from the ground, but they’ll find you eventually — usually during a heavy rain.
Gutters and Drainage
Gutters are part of the roofing system even though homeowners often treat them separately. A professional inspection looks at:
- Granule accumulation in gutters (a key indicator of shingle degradation)
- Gutter attachment and whether gutters have pulled away from the fascia
- Clogs and drainage failures that can cause water to back up under shingles at the eaves
- Downspout placement and whether water is being directed away from the foundation
Blocked gutters are one of the more avoidable sources of roof damage. Water sitting against the eaves creates ice dam conditions in winter and accelerates rot in the soffit and fascia year-round.
Ventilation Assessment
Roof ventilation is a system, not just a collection of components. Ridge vents, soffit vents, power ventilators, and attic fans all need to work together to maintain proper airflow. An under-ventilated attic traps heat in summer — accelerating shingle aging from below — and traps moisture in winter, which leads to deck rot and mold.
The inspector evaluates whether the ventilation intake and exhaust are properly balanced, whether vents are blocked by insulation or debris, and whether the current setup is adequate for the home’s attic volume.
Underlayment Condition
Where accessible, the inspector examines the underlayment — the secondary water barrier beneath the shingles. On older roofs, underlayment can degrade, wrinkle, or tear. In sections where shingles have been damaged or lifted, underlayment condition determines whether water infiltration is likely.
Roof Decking
The roof deck is the structural foundation beneath the shingles. The inspector looks for signs of soft spots, rot, or deterioration in the decking material. This usually requires accessing the attic and looking at the underside of the deck, where moisture infiltration shows up as staining, mold, or soft wood before visible damage appears on the roof surface.
Attic Conditions
A complete roof inspection includes the attic when accessible. The attic can reveal problems that aren’t yet visible from outside:
- Daylight visible through the roof deck (gaps, nail pops, failed areas)
- Water staining on rafters or decking indicating active or past leaks
- Mold or mildew from chronic moisture issues
- Insulation condition and coverage
- Evidence of pest intrusion through the roof system
Why DIY Inspection Has Real Limits
You can check your gutters and look at the ground around your downspouts. You can scan the roof from the ground with binoculars. But the meaningful findings — bruised shingles, failing flashing, early deck deterioration, ventilation gaps — require being on the roof or in the attic with a trained eye. Getting on a roof safely, particularly a steep-pitch roof, also involves equipment and technique that most homeowners don’t have.
Beyond safety, there’s interpretation. Knowing that a section of granule loss is consistent with hail damage versus normal weathering versus a manufacturing defect requires experience. Getting that interpretation wrong has real financial consequences for an insurance claim.
