Roof Inspections

What Happens During A Commercial Roof Inspection?

Perhaps you’ve seen water stains on your ceiling or water dripping from your roof recently. In any case, now is the moment to act and resolve your roof problems. What should you do first? Calling a few reputable commercial roofing companies for free and thorough inspections is the first step.

You want to compare the inspection reports, what rates they charge, what options they provide, and so on. This will assist you in determining the best solution for your building.

Most commercial roofing contractors will provide free inspections; if they don’t, choose someone else. Roofing contractors offer free inspections in the hopes of securing a project after their examination.

It stands to reason that the contractor who performs the finest exterior and interior inspection will most likely be granted the project. The best inspections are produced by:

  • Proposing a cost-effective, workable solution to your issue
  • Identifying every possible entry point for water into the building
  • Identifying HVAC, vents, pipes, gutter and downspout issues
  • Describing the issues and solutions in an easy-to-understand approach
  • Providing photo documentation of roof condition

We have made a wide range of roofing inspections, discoveries, and recommendations made to building owners at Longhorn Commercial Roofing.

But what happens during the inspection itself? Here, we’ll go through everything that happens during a commercial roof inspection, from beginning to end.

 

Commercial roof inspections starts from the inside

From the inside of the structure, a skilled roofing contractor will conduct a roof check. The purpose is to see where the water’s path comes to an end. Where the water stops on its route is a good indicator of where the leak started.

If you have water stains in your lobby’s tiles, for example, the position directly above the lobby on your roof is a good estimate of where the water is entering the building.

A puncture in that place is another sign. If an HVAC unit is located right above the lobby on the roof, it’s a good bet that the leak originates there.

 

Commercial roof inspections includes walking the roof

A competent roofing contractor will inspect the roof for particular conditions, such as:

  • Ponding water
  • Holes in the substrate
  • Cracks
  • Blisters
  • Uplifted seams
  • Uplifted nails and/or shingles
  • Incorrect / badly performed roof repairs
  • Trace roof leaks, HVAC flashings, gutters, drains, vents
  • Determine condition of previous roof installations

A roof inspector will begin at the edge and work their way towards the center of the roof. One reason is that you ensure that no part of the roof is overlooked. Another explanation is that the perimeter borders of the roof have a larger chance of generating a leak than the roof’s field.

The reason for this is that the perimeter edges of a roofing system can be lifted by the wind. On a single-ply roofing system, this usually leads the edges to lose adhesion before the roof’s field.

 

Commercial roof inspections include taking a few core samples

What is the definition of a core sample? A core sample is a small piece of roof that is removed to discover information about the roof’s field, such as:

  • How many sections of roofing are there?
  • What is the substrate made of?
  • The amount of moisture and/or saturation
  • The age of the roof

core sample

A core sample will inform you what type of decking is present (wood, steel, concrete, etc.) if there is a drop ceiling or if you can’t see the roof deck from the inside.

The number of core samples taken during a commercial roof inspection will vary depending on the roof’s size, slope, water flow path, and highlighted issues during the internal inspection.

For every 10,000 square feet of roof, a professional roofing contractor will take 1-2 core samples. Of course, a roofing contractor will patch the area where the core was removed using TPO or EPDM patches, or use silicone inside the area, around the core, and on top of the existing substrate to restore the area where the core was removed.

 

Reports are included in a commercial roof inspection

A full report will be sent to the building owner once the visual examination and core samples have been gathered.

The report will contain regions that are generating leaks, saturated areas on the roof, images of these areas, and recommendations for the future.

These suggestions may include whether your roof should be repaired, restored, or replaced. Here are some examples of when each of these might be useful:

Repair – only about 5% of your roof is saturated following your assessment, and there are only a few locations where water can enter the building. If the rest of your roof is in good shape, repairing these places is the most cost-effective option.

Restore – although less than 25% of your roof is saturated following your assessment, the remaining lifetime of your roof is less than 2-3 years. If no restoration is done before the end of the third year, a full tear off will almost certainly occur. The cost of a total tear off is estimated to be 3-4 times that of a restoration.

Replace – more than 25% of your roof is saturated after your assessment. It would be more cost-effective for roof replacement. This is comparable to replacing a high-cost automotive part (say, a $1200 transmission) on a 20-year-old vehicle that will almost certainly require additional repairs in the near future.

How long does a commercial roof inspection take?

“How long will a roofing contractor be on my property?” you might question. A roof inspection takes 30 minutes to 1 hour for a typical 20,000 sq. ft. commercial structure.

A roof inspection might take a short time or a lengthy time, depending on the following factors:

  • The roof has how many penetrations? (each one needs inspected thoroughly)
  • What is the total number of roof sections? (every section is inspected differently)
  • There are how many different types of roofs?

After the roof inspection is completed, you can relax and wait for the report to arrive.

 

What will be included in the inspection report?

The following items will be included in inspection reports:

  • the faults in your current roof system, with images and detailed explanations
  • what roof-repair solutions are available to you
  • a price estimate for the proposed work

After you’ve gathered a few estimates from different roofing companies, it’s time to compare them and pick the best selection for your company.
