What to Expect During a Professional Roof Inspection

April 13, 2026

An expert roof check provides property owners with some confidence, as well as prevents some expensive surprises. In commercial roof inspections, one particular area of interest is lights or flat roofs, which would be of particular interest to businesses due to their low slopes or flat roofs that, in most cases, conceal areas of problems such as water ponding or worn out membranes that, in effect, can produce significant leaks to the business. Although you work with roofing contractors Chicago, Roofing Contractor Charleston, or roofing contractors columbia sc, you can have a less stressful experience.


At 5 Stars Roofing, we perform a detailed inspection of residential and commercial buildings, with modern equipment and years of experience, to identify issues in their initial stages. Semiannual commercial roof inspections will prolong your roof and save thousands in repairs.


Step 1: The initial consultation and preparation


An inspection of your commercial roof or residential roof begins with a call or a web-based form. We enquire about the age of the roof, the exposure of the roof to weather, and the presence of any known problem, such as leaks or missing shingles. This assists us in preparing the appropriate tools and safety equipment.


We look into details of your property and check weather forecasts before coming, to make sure that everything is safe. With business customers, we liaise with the managers of buildings to limit disturbances. Check the time when we are 15 minutes early, with ladders, drones, moisture meters, and thermal cameras.


Step 2: Visual exterior examination


The inspection is initiated by walking around the building. For damage or blockage, we inspect the gutters, the downspouts, chimneys, vents, and flashing. In the case of commercial roof inspections, we examine the parapet walls, expansion joints, and HVAC units that may be putting stress on the membrane.


On the ground, we search out uneven settling, or erratic places, or loss of the granules on the shingles. Using drones, high resolution pictures can be taken in places of limited access, and workers will not face the risk of accidents.


Step 3: Getting on the roof


Safety comes first. Our roofing contractors in Chicago and our crews in Charleston and Columbia employ harnesses, guardrails, and non-slip shoes. Before climbing, we check surfaces to verify that they are stable.


We split it into sections on the roof: slopes, valleys, ridges, and edges. In the case of asphalt shingles, we look at cracks, curling, or bald spots. Metal roofs are checked for rust, loose bolts, and gaps between panels. Commercial roof inspections center on EPDM, TPO, or modified bitumen membranes by their seams, punctures, and alligatoring.


We also check flashing around penetrations, such as skylights, pipes, and AC units   they tend to be leak sources. Drainage systems are given special consideration so as not to pond.


Step 4: Interior and attic checks


There is no inspection that is complete without an inside look. We examine ceilings and look for water, mould, or insulation that is falling. Poor ventilation, rot, or daylight through cracks can be seen in attics.


Moisture meters and infrared cameras identify concealed insulation or wall leaks. Regarding commercial roof inspections, we examine mechanical rooms and HVAC ducts that we see to be intruded.


Step 5: Advanced diagnostics


Contemporary tools enhance the accuracy of inspections. Thermal imaging reveals deficiencies in temperature that showcase confined moisture. Drone thermography is used to effectively perform large commercial roof inspections.


Membrane thickness on flat roofs is tested with core samples or test cuts. We are also measuring slopes and examining correct installation codes.


Step 6: Detailed report and recommendations


Within 24 to 48 hours, you are provided with a detailed digital report. It incorporates pictures, videos, illustrations, and priority results. We describe little things going wrong (such as loose shingles), some short term repairs (leaks), and long term (replacement).
