Most homeowners have never seen the inside of a professional roof inspection. You know you should get one – maybe your roof is getting older, maybe you noticed a water stain on the ceiling, maybe a storm just ripped through Jacksonville and you want to know where you stand. But what actually happens when a licensed roofing contractor shows up to inspect your roof? What are they looking at? What are they looking for? And what do you get when it is over?

This is the complete step-by-step walkthrough of a professional roof inspection the way Campbell Construction performs them across Central Illinois. Every inspection we do follows this same thorough process whether you are in Jacksonville, Springfield, or anywhere in our service area. By the time you finish reading this you will know exactly what to expect, what your inspector is evaluating at each stage, and why each step matters for the long-term health of your roof.

A professional roof inspector with proper safety equipment examines the chimney area on a residential roof. Chimney flashing is one of the most common failure points on any roof and requires hands-on evaluation during every inspection.

Step 1: Scheduling & Arrival

The inspection process starts before anyone sets foot on your property. When you schedule a roof inspection with Campbell Construction we coordinate a time that works for your schedule. You do not need to take a full day off work – most inspections can be scheduled within a specific two-hour window, and we will confirm arrival by phone or text.

When the inspector arrives they will introduce themselves, confirm the scope of the inspection, and ask about any specific concerns you have noticed. Leaks, stains, missing shingles, granules in the gutters, drafts in the attic – anything you have observed helps the inspector know where to focus additional attention. If you have had previous roof work, storm damage claims, or repairs done by another contractor, this is the time to mention it so the inspector can evaluate that work as well.

Step 2: Ground-Level Exterior Assessment

Before anyone climbs a ladder the inspector walks the entire perimeter of your home at ground level. This is not a quick glance – it is a systematic evaluation of everything that connects to or interacts with your roof from below.

Gutters and downspouts. The inspector checks for sagging, separation from the fascia, visible clogs, and granule accumulation. Excessive shingle granules in the gutters are one of the earliest and most reliable indicators that your shingles are aging and losing their protective surface layer. The inspector also checks that downspouts are properly directing water away from the foundation.

Fascia and soffit. The wood or composite trim along the roofline is evaluated for rot, water damage, pest intrusion, and paint failure. Damaged fascia often indicates a problem above – a failing drip edge, clogged gutters, or ice dam history. Soffit vents are checked to confirm they are unobstructed, since blocked soffit vents directly compromise attic ventilation.

Siding and exterior walls near the roofline. Water staining, mold, or paint peeling on exterior walls just below the roofline can indicate flashing failure, gutter overflow, or ice damming. The inspector looks for these signs because they often reveal roof problems that would not be visible from the roof surface itself.

Step 3: Roof Access & Safety Setup

Once the ground-level assessment is complete the inspector sets up safe access to the roof itself. For most residential properties this means positioning a ladder at the appropriate pitch against a stable section of the eave. Professional inspectors use ladder stabilizers to prevent gutter damage and follow OSHA-compliant safety protocols.

For steeper roofs or multi-story homes the inspector may use a safety harness system with a roof anchor. This is not optional – any inspector who climbs a steep roof without proper fall protection is cutting corners on safety, which tells you something about how they will cut corners on the inspection itself. At Campbell Construction every inspector carries proper safety equipment on every job.

Step 4: Shingle or Membrane Condition Check

This is the core of the roof surface inspection. The inspector systematically walks the entire roof surface evaluating the condition of the primary roofing material – whether that is asphalt shingles, architectural shingles, or a flat roof membrane system.

For asphalt shingle roofs the inspector evaluates several specific conditions. Granule loss – bare spots where the protective ceramic granules have worn away or been knocked off by hail, exposing the underlying asphalt mat to UV damage. Cracking and curling – shingles that have dried out and are lifting at the edges or cracking through the body. Blistering – bubbles in the shingle surface caused by moisture trapped during manufacturing or installation. Missing or damaged shingles – tabs that have blown off, cracked through, or been displaced by wind or debris.

For flat or low-slope commercial and residential roofs, the inspector checks membrane integrity, seam adhesion, punctures, ponding water evidence, and surface deterioration. The inspector also evaluates the general uniformity of the roof surface – areas where the roofline sags or dips can indicate structural issues with the decking below.

Step 5: Flashing Inspection

Flashing failures cause more roof leaks than any other single issue. This is why a thorough flashing inspection is one of the most critical parts of the entire process. The inspector checks every flashing point on the roof – and most residential roofs have more than homeowners realize.

Chimney flashing. The step flashing and counter-flashing around chimneys is inspected for separation, rust, cracking, and sealant failure. Chimney flashing is the number one leak source on residential roofs because the junction between a vertical masonry surface and a sloped roof surface is inherently vulnerable to water penetration.

Vent pipe flashing. Every plumbing vent that penetrates the roof has a rubber boot and metal collar. The rubber degrades over time from UV exposure and temperature cycling. Cracked vent boots are among the most common – and most easily repaired – sources of roof leaks.

Skylight flashing. If you have skylights the inspector evaluates the flashing system around each one, checking for separation, sealant failure, and condensation evidence. Skylight leaks are notoriously difficult to diagnose because water can travel along the framing before it drips visibly inside the home.

Wall flashing. Where the roof meets a vertical wall – dormers, second-story walls, additions – the step flashing and kick-out flashing are inspected for proper installation and integrity. Missing or improperly installed kick-out flashing is one of the leading causes of hidden water damage in wall cavities.

Step 6: Ridge Cap & Peak Inspection

The ridge line at the peak of your roof takes more punishment than any other section. It is the highest point, the most wind-exposed, and the location of the ridge vent that provides critical attic ventilation. The inspector evaluates the ridge cap shingles for cracking, lifting, nail pops, and seal strip failure.

If your roof has a ridge vent the inspector checks that it is properly secured and not clogged with debris, insulation, or animal nesting material. A compromised ridge vent can dramatically reduce attic ventilation and lead to moisture problems, ice dams, and premature shingle aging. The inspector also looks for evidence of animal entry at the ridge line – squirrels and raccoons frequently target ridge vents as entry points into the attic.

Roof vents and their flashing are critical inspection points. The rubber boot around each vent pipe degrades over time from UV exposure and temperature cycling, making them one of the most common and easily repairable leak sources on residential roofs.

Step 7: Gutter & Drainage Evaluation

From the roof level the inspector gets a much better view of the gutter system than was possible from the ground. They evaluate gutter slope and alignment, checking that water flows properly toward downspouts without ponding in low spots. Standing water in gutters accelerates corrosion, attracts insects, and adds weight that pulls gutters away from the fascia.

The inspector also evaluates the drip edge – the metal strip along the eave that directs water from the roof edge into the gutter. Missing, damaged, or improperly installed drip edge allows water to wick behind the gutter and into the fascia board, causing rot that is invisible from the ground until the fascia fails completely. Valleys where two roof planes meet are checked for proper flashing, debris accumulation, and shingle wear patterns that indicate concentrated water flow.

Step 8: Attic Inspection

A roof inspection is not complete without evaluating the attic space below the roof deck. This is where many of the most serious – and most hidden – problems reveal themselves. If the attic is accessible the inspector evaluates four critical areas.

Ventilation. Proper attic ventilation requires balanced intake (soffit vents) and exhaust (ridge vent, gable vents, or powered vents). The inspector checks that intake vents are not blocked by insulation, that exhaust vents are functioning, and that the overall ventilation meets code requirements. Inadequate ventilation causes moisture buildup, ice dams in winter, and premature shingle aging from excessive attic heat in summer.

Insulation. The inspector evaluates insulation type, depth, condition, and coverage. Displaced or compressed insulation reduces energy efficiency and can block soffit vents. Water-damaged insulation indicates active or previous leaks that need to be traced to their roof-level source.

Moisture and mold. The inspector looks for water stains on rafters and decking, active moisture, condensation, and mold growth. Even small amounts of mold on attic framing indicate a ventilation or leak problem that will worsen over time. Catching moisture issues early prevents structural damage and costly remediation.

Daylight penetration. With the attic lights off the inspector looks for any pinpoints of daylight coming through the roof deck. Visible daylight means there is a gap in the roofing system – a missing shingle, a hole in the underlayment, or a flashing failure. If light can get in, water can get in.

Step 9: Photo Documentation

Throughout the entire inspection the inspector is taking photos. Not just a handful of snapshots – a comprehensive photo record of every area of the roof including both problem areas and areas in good condition. This documentation serves multiple critical purposes.

First, it creates a visual baseline of your roof’s current condition. If you have another inspection in a year or after a storm there is a documented comparison point to identify what changed. Second, if the inspection reveals damage that warrants an insurance claim, the photo documentation is essential evidence for the claims process. Insurance adjusters expect to see detailed photos showing the specific damage, its location on the roof, and the overall roof condition. Third, the photos help you understand exactly what the inspector found without having to climb on the roof yourself.

Thorough documentation is a hallmark of a professional roof inspection. Every finding is recorded with photos and detailed notes so the homeowner receives a complete picture of their roof’s condition.

Step 10: Written Report & Findings Review

The inspection concludes with the most important deliverable: a written report. A professional inspection report from Campbell Construction includes a summary of overall roof condition, specific findings organized by location and severity, photos documenting each finding, estimated remaining useful life of the roof system, and recommended actions ranked by urgency.

The inspector reviews this report with you in person whenever possible. They walk you through each finding, explain what it means in practical terms, and answer your questions. If the report identifies damage that should be addressed the inspector explains your options – whether that means a targeted repair, a partial replacement, a full roof replacement, or filing an insurance claim for storm damage. There is no pressure. The report is yours regardless of what you decide to do next.

How Long Does a Professional Roof Inspection Take?

A thorough professional roof inspection typically takes 45 to 90 minutes depending on the size and complexity of the roof. A simple ranch home with a single ridge line and no dormers can be completed in 45 minutes. A larger home with multiple roof planes, dormers, skylights, chimneys, and a complex gutter system may take the full 90 minutes or slightly longer.

Do not trust any inspector who claims to have completed a thorough inspection in 15 or 20 minutes. A proper evaluation of every component listed above cannot be rushed. If an inspector spends less than 30 minutes on a standard residential roof they are cutting corners.

When Should You Schedule a Roof Inspection?

There are several situations where a professional roof inspection is not just recommended – it is essential. Here is when Central Illinois homeowners should call to schedule one.

Annually. An annual inspection – ideally in spring before storm season or in fall before winter – catches developing problems before they become expensive emergencies. Think of it as preventive maintenance that protects a six-figure asset.

Before and after major storms. Central Illinois gets hit by severe weather regularly. If hail, high winds, or a tornado warning affected your area you should schedule a storm damage inspection within the following week even if you do not see obvious damage from the ground. Many forms of storm damage are invisible from street level but will cause leaks within months.

When buying or selling a home. A roof inspection should be part of every real estate transaction. Buyers need to know what they are inheriting. Sellers benefit from documenting roof condition before listing – it eliminates surprises during the buyer’s inspection and strengthens your negotiating position.

When your roof reaches 15 years. Even if you have had no problems, a 15-year-old roof in Central Illinois has absorbed significant weather exposure. An inspection at this stage gives you a realistic assessment of remaining useful life so you can plan and budget for eventual replacement rather than being surprised by an emergency.

When you notice warning signs. Granules in the gutters, water stains on the ceiling, missing shingles visible from the ground, higher energy bills, or musty smells in the attic all warrant an immediate professional inspection.

How Much Does a Professional Roof Inspection Cost?

This varies widely across the industry. Some companies charge $150 to $400 for a standalone inspection. Some home inspectors include a basic roof evaluation as part of a general home inspection but do not perform the level of detailed analysis described above.

Campbell Construction provides complete professional roof inspections at no cost. Our inspections are free for every homeowner across our Central Illinois service area – no strings attached. We do not charge for the inspection, the photo documentation, or the written report. We believe every homeowner deserves to know the condition of their roof without a financial barrier to finding out. If the inspection reveals damage that warrants repair or replacement we will provide options. If your roof is in great shape we will tell you that too. Either way, the inspection costs you nothing.

What to Do With Your Inspection Report

Once you have your written inspection report in hand, here is how to use it effectively. If no issues are found – file the report. It becomes a documented baseline of your roof’s condition on that date. If you file an insurance claim in the future this report proves the pre-storm condition of your roof. If minor issues are found – ask the inspector to prioritize the repairs by urgency. Small repairs like replacing a cracked vent boot or resealing a section of flashing are inexpensive and prevent much larger problems. If significant damage is found – ask whether the damage warrants an insurance claim. Storm-related damage is typically covered by homeowner’s insurance. Campbell Construction handles the entire claims process at no additional cost. If the roof is near end of life – start planning.
