A commercial roof fails differently from a shingle roof. It is waterproofed by a continuous membrane rather than by overlapping courses, so the vulnerable points are its terminations and interruptions rather than its field. The inspection is organised around that.

Interior and deck check

Ceiling staining, damp or displaced tiles, visible corrosion on deck or structure, and signs of moisture in insulation. Water entering at one point on a low-slope roof can travel laterally between layers and appear some distance away inside the building, so the interior symptom rarely marks the exterior source.

Drainage

Roof drains, scuppers, gutters and downspouts, checked for blockage and for whether water is actually leaving the roof. Ponding is recorded and located. Standing water increases load on the structure, accelerates degradation of many membrane types, and makes any small breach far more consequential than it would be on a surface that drains.

Membrane surface and seams

Open or lifting seams, punctures and tears, blistering, splits, surface wear, and damage from foot traffic around equipment. Seams are where single-ply systems most often let go, and they are inspected along their length rather than sampled.

Flashings and penetrations

Metal at vents, pipe boots, pitch pans, skylights and HVAC curbs, plus parapets, coping joints and perimeter edge detail. Most commercial roof leaks originate here rather than in the middle of a roof plane, which is why this is the part of the inspection that takes longest.

Twice a year is the common standard, in spring and autumn, with an additional inspection after any severe weather event.

The reasoning matters more than the interval. Two inspections a year mean the roof is seen after each season’s main stress: the freeze and thaw cycle on one side, the heat and storm season on the other. Inspecting after a storm means damage is found while it is still small and while its cause is still documentable.

Most manufacturers’ roof warranties also impose maintenance obligations on the building owner and exclude damage arising from neglect or blocked drainage. A documented inspection history is often what keeps that warranty in force.

We agree access arrangements in advance, including any site induction, key or hatch access, and restrictions on working hours around the business operating in the building.

The survey covers the roof surface, the drainage system, every penetration and flashing, the perimeter and parapets, and the underside of the deck where it is accessible from within. Findings are photographed as they are found, with their location recorded, rather than described afterwards from memory.

How long it takes depends on the size of the roof, how much rooftop equipment is installed, and how much of the interior is accessible. A small single-tenant building and a multi-unit retail centre are different jobs, and we will tell you what to expect when the visit is booked.

A written condition report. For each finding: a photograph, where it is on the roof, how serious it is, and what we recommend doing about it. Alongside that, an assessment of the roof overall and a realistic view of how much service life remains.

This is the part that separates an inspection from a look. A verbal opinion cannot be used to plan a budget, support a warranty claim, or evidence the condition of a roof before a storm. A dated report with photographs can do all three.

If the roof is sound and needs nothing, the report says so. A recommendation to do nothing is a legitimate outcome and we give it regularly.

There are three honest outcomes, and the report will say which applies.

Repair. Most commercial roof problems are localised and repairable. Seam failures, punctures, failed flashings and blocked drains are fixed without touching the rest of the roof. See commercial roof repair.

Maintain, or restore. A roof that is worn but structurally sound is often a candidate for a scheduled maintenance programme, or for a fluid-applied coating that renews the weathering surface without a tear-off. See roof maintenance plans and commercial roof coatings.

Replace. Saturated insulation across large areas, widespread membrane failure or a deteriorated deck put a roof past economic repair. Coating over retained moisture traps it in the assembly, where it keeps causing damage beneath an intact-looking surface, so restoration is not a way around a failed substrate.

We will not recommend a replacement where a repair would serve. The report shows you the evidence either way.

Warehouse and distribution. Large low-slope areas, usually single-ply or modified bitumen, with drainage and seam condition the main concerns.

Retail and strip centres. Multiple tenancies under one roof, where a single leak becomes several tenant complaints.

Office and medical office. Heavy rooftop equipment and the access traffic that comes with servicing it.

Churches and schools. Frequently a mix of steep-slope and low-slope areas on one building, with the junctions between them the weak point.

Apartment and multifamily. See multifamily roofing.

Restaurants and light industrial. Kitchen exhaust and process equipment, where grease and chemical exposure affect which membranes survive.

Good Shepherd Roofing holds Georgia general contractor licence GCCO009698, issued as a General Contractor Company licence. We have operated since 2016 and are rated 4.9 across 292 reviews.

We are based at 2505 2nd Ave, Dacula, GA 30019, and our crews work in this county. For commercial buildings that matters on the follow-up as much as the first visit: the firm that inspected the roof is the one that comes back when something changes.

We inspect commercial roofs throughout Gwinnett County, including Dacula, Lawrenceville, Buford, Duluth, Suwanee, Snellville and Braselton, and across North Georgia including Johns Creek, Winder, Auburn, Hoschton, Chamblee and Athens.

How often should a commercial roof be inspected?

Twice a year is the common standard, in spring and autumn, plus an additional inspection after any severe weather event. That way the roof is seen after each season’s main stress, and storm damage is found while it is still small.

How long does a commercial roof inspection take?

It depends on the size of the roof, how much rooftop equipment is installed, and how much of the interior is accessible. A small single-tenant building and a multi-unit retail centre are very different jobs. We will tell you what to expect when the visit is booked.

What do you check during a commercial roof inspection?

The membrane surface and seams, every flashing and penetration including HVAC curbs and pitch pans, the perimeter and parapets, the drainage system, and the interior and underside of the deck where accessible.

Do I get a written report?

Yes. You receive a written condition report with a photograph of each finding, its location, its severity and a recommendation, plus an assessment of the roof overall and its remaining service life.

Is a commercial roof inspection free?

Yes. There is no charge and no obligation. If the roof needs nothing, the report says so and there is nothing to pay.

Will an inspection tell me whether I need a repair or a full replacement?

Yes, and it will show you the evidence. Most commercial roof problems are localised and repairable. Replacement is indicated where insulation is saturated across large areas, the membrane has failed widely, or the deck has deteriorated.

Call (833) 477-7663 or book online. We will agree access, inspect the roof, and send you the written report.
