Recognize a problem at the roof peak
Missing or lifted cap pieces, exposed fasteners, split material, or debris from the top of the roof can warrant an inspection. A leak near the center of a home may have another source, so tell the contractor where staining appears and under which weather conditions. Ground-level photographs can help explain the concern without climbing onto the roof.
The ridge is more than a sealant line
Asphalt ridge caps, tile ridge assemblies, and ventilated ridge systems use different components. Blanket sealing can interfere with a vented assembly rather than repair it. Ask whether the proposal replaces damaged pieces, corrects attachment, and repairs the underlying detail. For tile peaks, the contractor should identify the existing system before proposing a matching repair.
Look at the adjacent roof slopes
Wind-related movement may affect the ridge and nearby field shingles together. If the upper roof shows a broader pattern of damage, shingle replacement may be part of the scope. Deteriorated material beneath the cap can also change what must be removed. A defined repair boundary helps prevent piecemeal work that leaves an adjacent defect untreated.
Questions to settle before authorizing work
Request a description of the replacement cap, the ridge-vent treatment where applicable, and any visible finish difference. Ask who supplies photographs after completion and what the written warranty actually covers. High roof peaks can require additional access and fall-protection arrangements, so a price based only on the length of the ridge may omit important parts of the work.
Prepare for the assessment
From a safe ground position, note whether damage runs along the whole peak or appears in one place. Mention any recent attic ventilation work, since the contractor should understand changes made to the ridge assembly before recommending repair.

Frequently asked questions
Should a ridge vent be sealed shut to stop water?
Not as a default repair. Have the vent, its installation, and the source of water entry assessed before changing ventilation.
Can you quote from a ground photograph?
A photograph may help an initial discussion, but the provider may need an inspection to establish the condition and complete repair scope.
