The roof is a building’s first barrier against extreme weather and temperature. Be it a thick layer of snow dropping from the night before or strong winds rummaging through town; your roof takes the brunt of it all. You could already face much more extensive problems when you place blind trust in your commercial site’s roofing and completely neglect it. Some of these issues can be mold growth, rotten wood, damaged insulation, and other unwanted structural issues.

A roof inspection is one of those most crucial preventative measures to ensure and maintain your building’s overall structural integrity. With over 30 years of professional experience up our sleeves, we at DDP Roofing Services, Inc. conduct comprehensive roof inspection services to make sure your commercial site is at its best at all times.

This article will go through some of the most common commercial roof problems you wouldn’t want to turn a blind eye to and a checklist of points that will come in handy on your next scheduled roof inspection.

Why do you need a commercial roof inspection?

Most commercial building owners only recognize the need for a thorough roof inspection to determine whether their roof survived the damage only after a hailstorm or other significant weather event. However, that shouldn’t be the only time you consider your roof’s wellbeing.

A regular commercial roof inspection is a must if you want to avoid huge repair costs in the future. Proper roof maintenance can extend your roof’s life for up to 20+ years – and it all begins with inspection.

DIY Inspections vs. Professional Inspections

Most building owners can spot fundamental roof problems like missing or flapping shingles. While other issues, such as leaking, discolorations, and mold growth, can only be recognized once the symptoms are more prominent.

However, other issues are not visible to the untrained eye, so getting an opinion from a professional is crucial. If your commercial roof is new, shows no damage, and hasn’t experienced extreme weather conditions since its last inspection, a visual inspection from the ground will do.

In any other case, however, a comprehensive roof inspection should be accomplished by a roofing professional who knows what to look for.

Common Problems of Commercial Roofs

Because roofs are inherently vulnerable, problems are bound to develop. DDP Roofing Services, Inc.’s roof inspection services aim to catch these problems sooner rather than later. Here are the most common issues we encounter in our clients’ commercial roofs:

Roof Leaks

A small roof leak is not a small problem, yet it is the most common roof issue we observe. Therefore, we recommend an immediate repair to avoid water intrusion and property and equipment damage due to exposure to moisture.

Ponding Water

When a roof’s drain gets clogged, you might notice a water pond on top. We advise you not to let ponding water remain longer than two days to avoid roof deterioration and damage to the roof structure.

Lack of Maintenance

The roof is one-third of your building, and it is in your best interest to keep it in tip-top shape. Therefore, DDP Roofing Services, Inc. recommends that you contact us twice every year so that we can conduct inspections and preventive services for your roof.

Commercial Inspection Checklist

This step-by-step guide will walk you through the checklist of things you should expect from a commercial roof inspection conducted by roofing professionals.

Internal Structure

A roof inspection starts inside the building – checking water routes, stains, rust, penetration, corrosion, and other noticeable water damages. Tracking the water routes will give us an idea if there are existing leaks and problems in your roof, even before we see the top itself.

Building Envelope

The building envelope will determine if your roof has structural defects as we look closely at it. We’ll look for cracks in the structure, as well as possible routes of water entry.


DDP Roofing Services, Inc. uses a drone to observe possible faults in the roof. Here, we inspect roof leaks, ponding water, drained clogs, cracks, holes, and blisters.

Roof Perimeter And Field

We also note the perimeter’s condition, as it is more prone to damage than the field. We pay attention to drainage systems, gutters, coping joints, and flashings.

Roof Accessories

We inspect buildings with roof accessories if they are the root cause of your roof problems. We will check for poor installation and malfunction in supplements, drains, seals, and many more.

Reports And Solutions

Upon inspection, DDP’s Roof-Life software provides you with a comprehensive report. We will notify you of possible and existing problems your roof may have, and it categorizes these issues into Monitor, Repair, or Replace. Additionally, our experts can advise you with value-engineered solutions.
