A professional roof inspection documents the whole roof system with photos and written findings, then sorts the result into maintenance, repair or replacement.

A professional roof inspection covers the roof surface, flashing, penetrations, valleys, drainage and ventilation, checks the attic for moisture clues when it is accessible, and ends with photos and findings you can keep. It should tell you whether the roof needs maintenance, a repair or replacement. A contractor glancing up from the driveway and quoting a price is not doing an inspection.

Quick navigation

More Than a Visual Check

A real inspection follows the roof as a system: from ridge to eaves, from the exterior surface into the attic where access allows, and from the obvious areas to the details that are easy to skip.

The goal is not just finding damage but understanding the condition of the whole roof.

What a Complete Inspection Covers

Exterior surface

The inspector walks the roof where it is safe to do so and checks the roofing material: curling, lifted edges, cracking, granule loss on asphalt shingles, and soft spots underfoot that may indicate deck damage. The ridge, hips and field of the roof are all part of the check, not just the areas visible from the ground.

Attic and decking clues

The attic often tells a different story. Staining on sheathing or rafters, damp insulation and dark streaks near penetrations or eaves can show leak paths that have not appeared on the ceiling yet. Not every inspection allows attic access, but when it does, it adds useful context.

Flashing, penetrations and transitions

Flashing around chimneys, skylights, vents and wall intersections should be examined directly. Lifted, cracked, corroded or poorly sealed flashing is a common source of leaks and easy to miss if nobody looks for it.

Valleys and drainage

Valleys carry concentrated water. Look for debris buildup, worn or corroded valley metal and lifted shingles where two slopes meet. Gutters and the points where water leaves the roof belong in the review as well.

Ventilation

Ventilation affects roof life, not just comfort. Poor airflow can trap moisture in the attic, which over time can damage sheathing and shorten the life of roofing materials. The inspection should note intake at the eaves, exhaust near the ridge and any obvious imbalance.

Photo documentation

Significant findings should be photographed: flashing condition, granule loss, moss, valley wear, not just the worst spot. Photos give you a record and a way to compare what different contractors report.

What Fails First in Western Washington

Some parts of a roof wear out sooner in a wet, windy climate, so a thorough inspection gives them extra attention:

  • Valleys. Large water volume, debris and wear where two planes meet.
  • Flashing. Sealants age, metal corrodes and gaps open slowly at chimneys, skylights, vents and walls.
  • Wall transitions. Where a roof meets a vertical wall is a high-risk detail.
  • Penetrations. Each pipe or vent is an entry point if its boot or seal fails.
  • Edges and eaves. Wind-driven rain gets under lifted edges.
  • Moisture points tied to ventilation. Trapped attic moisture can damage decking before the roof surface shows any sign.

Why the Climate Changes the Inspection

A roof inspected in a hot, dry region is checked mostly for sun and heat damage. Here the issues are different.

Wind-driven rain. Ordinary rain falls onto the roof. Wind-driven rain is pushed sideways under flashing and into wall transitions.

Moss and debris. Moss holds moisture against the surface, can lift shingle edges and collects debris in valleys.

Coastal exposure. Roofs near the water face sustained wind and salt air, which affect how flashing and fasteners age. Wind Proof Roofing works across Whidbey Island, Anacortes and the North Puget Sound, where this exposure is common.

What a Good Inspection Should Tell You

The answer should be more nuanced than “replace or don’t.” It should place the roof in one of these categories:

  • Maintenance only. Moss treatment, debris clearing, minor sealant work. The roof is in reasonable shape.
  • Isolated repair. One or two specific problem areas, such as a flashing detail or a failed penetration seal, with useful life remaining elsewhere.
  • Broader repair. Several areas need attention, or repairs are becoming complex enough that replacement timing is worth discussing.
  • Replacement. The roof is past its useful life, repairs would be short-term, or damage is extensive.

Knowing which category applies helps you plan and judge any proposal you receive.

What You Should Receive Afterward

  • Photos of significant findings, organized so you can tell what each shows
  • Written findings in plain language, not only a verbal summary
  • An explanation of what is urgent, what can wait and what it means for the roof’s remaining life
  • Repair vs. replacement context before anyone asks you to sign
  • Scope options where there are genuine choices

If a contractor visits your roof and hands you only a total price, that is a quote, not an inspection.

How to Compare Inspection Scopes

  • Are findings documented with photos, or is there only a number?
  • Are flashing, valleys, penetrations and ventilation named, or is the scope vague?
  • Does the report separate urgent items from items that can wait?
  • Is there a plain explanation of what is failing and why?
  • Does it address the attic or decking, or explain why access was limited?
  • Does it distinguish repair options from replacement options?
  • Are drainage and wall transitions part of the review?
  • Does the contractor say what cannot be confirmed before tear-off?

Red flags

  • No photos after the visit
  • A quote with no scope of work behind it
  • Pressure to decide the same day
  • “Full inspection” with no description of what it includes
  • Skipping the attic with no explanation
  • Findings that never mention flashing, valleys or penetrations

Two contractors can examine one roof and report very different things because they looked at different details. For more on reading proposals, see our guide on how to compare standing seam metal roof quotes in Seattle.

When to Call a Pro

  • Visible leak or interior staining. The source is often not directly above the stain.
  • After a wind or storm event. Fasteners lift, flashing shifts and edges are damaged in ways that are not visible from the ground. See roof insurance claims for wind damage in Washington if storm damage is a factor.
  • An aging roof. Age alone justifies a current assessment, even without symptoms.
  • Repeated repairs. Problems that keep returning to the same area often point to a system issue.
  • Moss or debris buildup. These are signs of a moisture condition worth assessing.
  • Buying or selling a home. A documented inspection reduces surprises for both sides.

FAQ

Isn’t an inspection just checking for missing shingles?

No. Missing shingles are visible from the driveway. A real inspection also covers flashing, valleys, penetrations, drainage, ventilation and attic clues, which is where much leak damage starts.

What should I get after an inspection?

Photos of specific findings, a written or clearly explained summary, a split between urgent and non-urgent items, and context on repair versus replacement. If you only receive a price, ask for the supporting documentation.

Can an inspection tell me whether I need repair or replacement?

In most cases it can give a clear picture of the roof’s condition and remaining life. Some things, such as the full extent of deck damage, may only be confirmed at tear-off, and a good inspector will say what can and cannot be determined beforehand.

Should attic moisture or ventilation be part of an inspection?

At least noted. Ventilation problems can damage attic sheathing before the roof surface shows anything. When access is available, staining, damp insulation or dark sheathing affect both the repair scope and how long the next roof will last.
