How to Read Your Roof Inspection Report (And What to Ask Your Roofer)

You just had a roof inspection. The roofer hands you a report — maybe it is a few pages, maybe it is ten — and it is full of terms like "granule loss," "flashing separation," and "decking deterioration." You nod, you thank them, and then you get home and realize you have no idea what half of it means or what you are actually supposed to do next.

That is normal. Roof inspection reports are written by roofers for other roofers. Most homeowners have never been taught how to read one, and most roofers do not take the time to walk through it in plain language.

I want to fix that. Here is how to read your roof inspection report, what the terminology actually means, and — just as important — what questions you should be asking before you agree to anything.

The Three Sections You Will See in Every Report

Most inspection reports follow the same general structure, even if the formatting varies from company to company.

1. Summary of Findings. This is the overview. It should tell you the general condition of the roof, the estimated age of the materials, and a high-level assessment — usually something like "good," "fair," or "poor," or a numerical scale. This section gives you the big picture. If your report does not have a clear summary, ask for one. You should not have to dig through ten pages of notes to understand where your roof stands.

2. Detailed Findings and Recommendations. This is the section with the specific issues — what was found, where it was found, and what the inspector recommends doing about it. Good reports break this down by area of the roof (front slope, back slope, valleys, ridgeline, penetrations) and rank issues by severity. This is where you will see the technical terms that I will decode below.

3. Photo Documentation. Photos matter more than anything else in the report. Words can be vague. A photo of a cracked pipe boot or a dented ridge vent tells you exactly what the inspector saw. If your report does not include photos, ask why. If it includes photos but they are not labeled or connected to specific findings, ask the inspector to walk you through them.

Decoding the Terminology

Here are the terms that trip up homeowners most often, in plain language.

Granule loss. Asphalt shingles are coated with tiny ceramic granules that protect the shingle from UV damage. When those granules wear away — from age, hail, or foot traffic — the shingle loses its protection. Mild granule loss is normal on older roofs. Heavy granule loss means the shingles are nearing the end of their useful life. If your gutters are full of what looks like coarse sand, that is granules.

Bruising and creasing. These are types of hail damage. Bruising means the shingle was hit hard enough to fracture the fiberglass mat underneath, even if the surface looks intact. You can sometimes feel it — the spot will be soft or spongy compared to the surrounding area. Creasing is a visible line or fold in the shingle, also caused by impact. Both compromise the shingle's ability to shed water.

Lifted shingles and exposed nails. Wind can lift shingle tabs and break the sealant strip that holds them down. Once a shingle is lifted, rain can get underneath. Exposed nails — either from improper installation or from shingles that have shifted — are direct entry points for water. Neither of these is catastrophic on its own, but both need to be addressed before they cause leaks.

Flashing gaps or separation. Flashing is the metal material installed at transitions — where the roof meets a wall, around chimneys, in valleys, around pipe boots. Its job is to direct water away from these vulnerable areas. When flashing separates, corrodes, or develops gaps, water finds its way in. Flashing failures are one of the most common causes of roof leaks, and they are often repairable without replacing the entire roof.

Buckling. Shingles that are curving upward from the middle of the tab, creating a visible ridge or wave across the roof surface. Buckling is usually caused by moisture in the decking below or by improper installation. It is a structural issue, not just cosmetic.

Curling. The edges of the shingle turn upward. This happens when the asphalt in the shingle dries out over time, causing the edges to contract. Curling is an age-related issue and a sign that the shingles are losing flexibility. Curled shingles are vulnerable to wind lift and water intrusion.

Decking issues (soft spots, dark stains, rot). The decking is the wood surface — plywood or OSB — that sits under your shingles and underlayment. It is the structural foundation of your roof. When inspectors note dark stains, soft spots, or rot in the decking, that means water has been getting through for a while. This is serious. Damaged decking needs to be replaced before new roofing material goes on top.

Ponding. Water pooling on the roof surface instead of draining off. More common on flat or low-slope sections. Ponding accelerates shingle deterioration and can lead to leaks.

Sagging. Visible dips or sag lines in the roofline. This indicates potential structural issues — either the decking is deteriorating or the support structure underneath is compromised. Sagging is never cosmetic. It always needs investigation.

Understanding the Grading

If your report includes an overall grade or rating, understand what it means and what it does not mean.

A rating of "fair" does not necessarily mean you need a new roof. It might mean there are a few items that need attention but the system as a whole is performing. Conversely, a rating of "good" does not mean you can ignore every finding in the report. There might be a specific issue — a flashing gap, a cracked pipe boot — that needs a repair now even though the overall roof is in decent shape.

Focus less on the grade and more on the specific findings and their severity. A grade is a summary. The details are where the decisions get made.

The Four Questions You Should Always Ask

After you have read through the report, here are the questions that will tell you everything you need to know.

1. What needs attention right now versus what can I monitor? Not every finding is urgent. Some items are "fix this before the next heavy rain" and some are "keep an eye on this over the next year or two." A good roofer will prioritize clearly. If everything in the report is presented as urgent, ask them to rank the items. If they cannot or will not, get a second opinion.

2. Is this storm damage or normal wear and tear? This distinction matters for one critical reason — insurance. Storm damage from hail or wind is typically a covered event under your homeowner's policy. Normal wear and tear is not. If the report shows damage that could be storm-related, you want to know that before making decisions about how to pay for it.

3. Does this affect my insurance claim? If you are filing or considering an insurance claim, your inspection report is a key document. Ask your roofer whether the findings support a claim, what the adjuster is likely to approve, and whether the damage is documented thoroughly enough for the claims process. At Alta, we work with homeowners through the insurance process every day, and we make sure our reports are detailed enough to stand up to adjuster review.

4. How urgent is each item? Get a timeline. "This flashing needs to be sealed before the next rain" is a very different conversation than "this granule loss is consistent with a 15-year-old roof and you should plan for replacement in the next 3-5 years." You need to know the difference so you can budget and plan accordingly.

A Good Report Should Make Things Clearer, Not More Confusing

If you finish reading your roof inspection report and feel more confused than when you started, the report is not doing its job. A quality inspection should give you a clear picture of your roof's condition, a prioritized list of what needs attention, and enough documentation to make informed decisions — whether that is a small repair, a full replacement, or doing nothing right now.

If your current report does not give you that clarity, or if you want a second set of eyes on your roof, we are happy to help. We do thorough inspections with full photo documentation, and I will walk you through every finding in plain language so you understand exactly where your roof stands.
