Commercial property owners have a lot on their plates, from managing tenants to maintaining the building’s infrastructure. One of the most critical yet often overlooked aspects of property maintenance is the roof.

Neglecting your commercial roof can lead to severe issues, including:

Structural damage
Significant financial loss
Mold growth

This blog post aims to provide you with a guide on commercial roof repair, covering what makes it different from residential roof repair, signs you need it, common sources of damage, costs, and insurance considerations.

What Makes Commercial Roof Repair Different from Residential Roof Repair?

Most of us have some familiarity with residential roofs. However, commerical roofs can be quite different.

Scale and Complexity: Commercial roofs are generally much larger than residential roofs, often spanning thousands of square feet. This scale makes them more challenging to inspect, maintain, and repair. Additionally, commercial roofs are typically flat or have a low slope, which presents unique drainage and maintenance challenges compared to the steep pitches of residential roofs.
Materials and Techniques: The materials used in commercial roofing are often different from those used in residential roofing. While residential roofs commonly feature asphalt shingles, commercial roofs may use materials like TPO, EPDM, PVC, or built-up roofing (BUR). Each of these materials requires specialized knowledge and techniques for repair.
Functionality: Commercial roofs often house essential equipment such as HVAC systems, vents, and communication devices, which can complicate repair efforts. The presence of this equipment means that any repair work needs to be planned meticulously to avoid disrupting building operations.

Signs You Need Commercial Roof Repair

Not sure whether it’s time to call in pros or not? Here are a few signs that you are in need of roof repair.

💧 Leaks and Water Stains

One of the most apparent signs that your commercial roof needs repair is the presence of leaks or water stains on the ceiling. Even small leaks can indicate significant underlying issues that require immediate attention.

🫧 Blistering or Bubbling

Blistering or bubbling on the roof surface is a clear sign that moisture has become trapped under the roofing material. This issue can lead to more severe problems if not addressed promptly.

🌊 Ponding Water

Flat commercial roofs are particularly susceptible to ponding water, which occurs when water accumulates in low areas and doesn’t drain properly. Prolonged ponding can deteriorate roofing materials and lead to leaks.

🏚️ Cracks and Splits

Cracks or splits in the roofing material can be caused by various factors, including temperature fluctuations and heavy foot traffic. These imperfections can worsen over time and lead to more extensive damage.

⚡️ Increased Energy Bills

A damaged roof can compromise your building’s insulation, leading to higher energy bills. If you notice a sudden spike in heating or cooling costs, your roof may be the culprit.

🍄 Mold and Mildew

The presence of mold or mildew inside the building can indicate that moisture is entering through the roof. Mold and mildew are not only health hazards but can also signify more extensive roofing issues.

Common Sources of Commercial Roof Damage

Commercial roof systems are relatively sturdy but even they can be susceptible to damage. Here are some common sources:

Weather Conditions: Extreme weather conditions, such as heavy rain, snow, hail, and high winds, are among the most common causes of commercial roof damage. These elements can wear down roofing materials over time and cause immediate damage during severe events.
Poor Installation: Improper installation is another significant source of commercial roof damage. If the roof was not installed correctly, it might not perform as expected, leading to premature wear and tear.
Lack of Maintenance: Routine maintenance is crucial for the longevity of a commercial roof. Neglecting regular inspections and upkeep can result in minor issues becoming major problems.
Foot Traffic: Commercial roofs often experience heavy foot traffic due to the presence of HVAC systems and other equipment. This foot traffic can cause wear and tear on the roofing material, leading to cracks and other forms of damage.
Mechanical Equipment: Mechanical equipment on commercial roofs, such as HVAC units, can contribute to roofing issues. Improperly installed or maintained equipment can cause punctures, tears, and other damage to the roof.

10 Step Guide for Commercial Roof Repairs

Want to know what the repair process is like? Here are the steps the pros follow!

Step 1: Assess the Damage

Begin by thoroughly inspecting the roof to identify the extent of the damage. Look for visible signs such as cracks, blisters, or missing shingles. Document your findings with photos and notes.

Step 2: Evaluate the Cause

Determine the cause of the damage. This may involve checking for underlying issues such as leaks, improper drainage, or problems with mechanical equipment. Knowing the cause is crucial for effective repairs.

Step 3: Gather Necessary Tools and Materials

Before beginning repairs, collect all needed tools and materials. Depending on the type of roof, this may include roofing membranes, patching materials, sealants, and safety equipment.

Step 4: Implement Safety Precautions

Ensure safety by wearing appropriate gear such as helmets, non-slip shoes, and harnesses if working at heights. Utilize scaffolding or ladders securely to avoid accidents.

Step 5: Make Temporary Repairs

If the damage is significant, consider making temporary repairs to prevent further issues until permanent fixes can be completed. Use tarps or roofing cement to cover critical areas.

Step 6: Perform Permanent Repairs

Following safety protocols, execute the necessary permanent repairs. This could involve replacing damaged sections, sealing leaks, or installing new flashing to protect vulnerable areas.

Step 7: Conduct a Thorough Inspection After Repairs

Once repairs are completed, conduct a final inspection to ensure that all work is done properly and no further issues remain. Check for uniformity and consistency in materials used.

Step 8: Document Repairs

Keep detailed records of all repairs made, including dates, materials used, and costs incurred. This will be valuable for future maintenance and insurance purposes.

Step 9: Schedule Regular Maintenance

To prolong the life of the roof, establish a routine maintenance schedule. Regular inspections and upkeep can help prevent damage from occurring in the first place, saving time and money in the long run.

Step 10: Consult a Professional if Needed

If the damage is extensive or beyond your skill level, don’t hesitate to contact a professional roofing contractor. Their expertise can ensure that repairs are done correctly and safely.

Cost of Commercial Roof Repairs

Many people hesitate to take care of their commercial roofing systems because they are worried about the costs. But with a little preparation, you’ll quickly find that the costs might not seem as intimidating as you think.

Factors Influencing Repair Costs

The cost of commercial roof repairs can vary widely depending on several factors, including the extent of the damage, the type of roofing material, and the complexity of the repair.

Average Costs

On average, commercial roof repairs can range from $3 to $10 per square foot. However, more extensive repairs or those requiring specialized materials can cost significantly more. For a more accurate estimate, it’s essential to get a professional assessment.

Budgeting for Repairs

Given the potential costs, it’s wise for commercial property owners to set aside a budget for roofing repairs. Regular maintenance can also help identify and address issues before they become more costly.

Will Insurance Cover Commercial Roof Repairs?

You can also save money by filing an insurance claim if the damage is covered under your policy. Not sure? Here are some things to check for.

Understanding Your Policy

Whether or not your insurance will cover commercial roof repairs largely depends on your policy’s terms and the cause of the damage. Most commercial property insurance policies cover damage caused by unforeseen events like storms or fires. However, damage resulting from neglect or lack of maintenance is typically not covered.

Filing a Claim

To file an insurance claim for roof repairs, you’ll need to document the damage thoroughly. This documentation should include photos, a detailed description of the damage, and any quotes or assessments from professional roofing contractors.

Working with an Adjuster

Once you’ve filed a claim, an insurance adjuster will likely inspect the damage. It’s beneficial to have your roofing contractor present during this inspection to ensure that all damage is adequately documented and addressed.

Tips for Maximizing Your Claim

Document Everything: Keep detailed records of maintenance and repairs.
Act Quickly: Promptly address any issues to prevent further damage.
Understand Your Policy: Familiarize yourself with your policy’s terms and conditions.
