A professional roof inspector walks your roof and your attic looking for four broad categories of trouble: surface damage (missing or cracked shingles, granule loss, deterioration), flashing and seal integrity around penetrations like chimneys and vent pipes, structural soundness in the deck and framing below the shingles, and moisture indicators that signal leaks above or condensation problems below.
The inspection covers both the outside and the inside of the roof system, which is why a thorough job typically takes 45 minutes to two hours, depending on the home’s size and complexity.
The full list of what gets checked is longer than most homeowners realize. Roofs are layered systems where one weak component can compromise the whole structure, and a good inspector catches the small issues before they turn into expensive emergencies.
The Exterior Checklist
The visible roof surface gets the most attention because that’s where most damage shows up first. An inspector walking your roof is looking for:
- Missing, cracked, curling, or lifted shingles across all sections
- Granule loss on asphalt shingles (often pooled in gutters or downspouts)
- Damaged or rusted flashing around chimneys, skylights, vent pipes, and roof valleys
- Sealant deterioration at any penetration through the roof surface
- Sagging sections that indicate underlying structural weakness
- Algae streaks, moss, or organic growth that traps moisture against the shingles
- Damaged ridge caps and starter strips along the roof edges
- Loose or compromised gutters that affect water flow away from the roofline
- Punctures or impact damage from fallen branches, hail, or foot traffic
Each of those items receives a status note in the inspection report. Repair recommendations follow only when something actually needs attention.
The Attic Checklist
The attic tells a story the roof exterior doesn’t. A professional roof inspector spends significant time inside the attic looking for evidence of issues that show up below the shingles before they’re visible above. Water stains on the underside of the roof deck, damp insulation, daylight visible through the boards, signs of pest activity, and mold growth in the corners all give the inspector data the exterior alone can’t provide.
Ventilation gets close attention here too. Improper airflow leads to moisture buildup in the attic, which shortens the life of the roof from below. The EPA’s guidance on indoor air quality and moisture control confirms that condensation issues in attics often connect directly to the conditions you experience in living spaces below.
Structural and System Checks
Beyond shingles and attic conditions, the inspector evaluates the structural elements that hold the roof together. The roof deck (the sheathing underneath the shingles) needs to be solid, with no soft spots or rot. Rafters and trusses should be straight and free of cracks. Insulation should be properly distributed with no compressed or wet sections.
Components like vent pipes, plumbing boots, chimney crowns, and skylight seals all get individual review. Solar panels, where installed, require their own checklist for mounting integrity and any roof penetrations associated with the system. Older homes may need additional attention to ice dam history, which leaves telltale signs along the eaves and lower roof edges.
What Each Roof Type Needs
Different roofing materials get inspected differently. The table below outlines the focus areas for the most common types:
| Roof Type | Inspector Focus Areas |
| Asphalt Shingles | Granule loss, curling, missing tabs, flashing seals |
| Standing Seam Metal | Panel seams, fastener integrity, finish wear |
| Tile or Slate | Cracked or slipped pieces, underlayment exposure |
| Flat Roofs | Membrane condition, pooling water, seam integrity |
| Cedar Shake | Splitting, curling, moss buildup, fastener corrosion |
A licensed roofing contractor inspects each material against its specific failure modes rather than applying a one-size checklist. For more on materials and what affects their longevity, our roof replacement service page walks through the options.
When to Schedule an Inspection
Most homeowners benefit from an annual roof inspection, ideally in spring after winter weather has tested the roof. Beyond the annual visit, schedule an inspection any time the following happens:
- After a severe weather event (hail, high winds, fallen tree branches)
- Before buying or selling a home
- When filing an insurance claim for storm damage
- If you notice interior signs like water stains, peeling paint, or sudden energy bill spikes
- When the roof is approaching the end of its rated lifespan
Catching issues early genuinely saves money. A small flashing repair caught during a routine inspection costs a fraction of what the same problem becomes once water has reached the attic insulation, the ceiling drywall, and the room below.
What’s in the Inspection Report
A professional inspection report should give you more than a thumbs up or thumbs down. The documentation typically includes:
- Photos of every problem area, dated and labeled
- Specific notes on each component checked, including ones that passed
- A repair priority list distinguishing immediate fixes from monitoring items
- Estimated remaining lifespan for the current roof system
- Recommendations for maintenance between inspections
Good reports also serve as documentation for insurance claims and real estate transactions. If you’re filing a claim for storm or hail damage, the photo and written record from a recent professional inspection carries weight with insurance adjusters that a self-reported claim doesn’t.
Common Questions
How much does a professional roof inspection cost?
Pricing varies by region, home size, and roof complexity. We provide free roof inspections for Monmouth County homeowners as part of our standard service, which is why most people skip the third-party route and call us directly for the same level of documentation.
How often should I have my roof inspected?
Annually for most homes, plus after any major storm. Older roofs (15 years and up) benefit from twice-yearly inspections to catch end-of-life issues early.
Do I need to be home for the inspection?
Helpful, not required. Most of our inspections are completed with the homeowner on site for the walkthrough, but we can also send the report afterward if your schedule doesn’t allow it.
What’s the difference between a roof inspection and a home inspection?
A home inspector reviews the roof briefly from the ground or eaves as part of a broader property review. A roof inspector walks the roof, enters the attic, and provides specialized documentation of the roofing system specifically.
Will the inspector try to sell me a new roof?
Not from us. The inspection report includes honest recommendations based on what we find. If repair is the right call, that’s what we recommend.
The Easier Way to Know What Your Roof Needs
Climbing the ladder, walking the roof, and reading the attic are jobs we’d rather do for you. Our roof inspections are free, written up properly, and come with the photo documentation that holds up under insurance review or a future home sale.
