When it comes to commercial properties, the roof is often out of sight and out of mind. However, neglecting commercial roof maintenance can lead to:

  • Costly repairs
  • Structural damage
  • Business interruptions

In this blog, we’ll delve into the intricacies of commercial roof maintenance, covering everything from its unique features to essential maintenance routines, signs of damage, and when to seek professional help.

What Makes a Commercial Roof Unique

Commercial roofs differ from their residential counterparts in several key aspects. Firstly, they tend to cover larger areas, often spanning multiple stories and housing complex HVAC systems, skylights, and other installations.

Additionally, commercial roofs may have different materials and designs tailored to specific business needs, such as flat roofs for easier installation of equipment or green roofs for environmental benefits.

Moreover, commercial roofs are subject to heavier foot traffic, exposure to industrial pollutants, and potential damage from neighboring structures like HVAC units or satellite dishes. These factors increase the wear and tear on commercial roofs, necessitating specialized maintenance approaches.

Why Maintenance is Crucial

Maintenance is the cornerstone of preserving the integrity and longevity of any commercial roof. Here’s why it’s so important:

  • Cost Savings: Regular maintenance helps identify and address minor issues before they escalate into major problems, saving you significant repair costs in the long run.
  • Prolonged Lifespan: Proper maintenance can extend the lifespan of your commercial roof, maximizing your return on investment.
  • Protection of Assets: A well-maintained roof protects your property, inventory, and equipment from water damage, leaks, and structural deterioration.
  • Compliance and Safety: Regular maintenance ensures that your roof meets building codes and safety standards, reducing the risk of accidents and liability issues.
  • Business Continuity: Avoiding unexpected roof failures or leaks helps maintain business operations without interruptions due to structural damage or water infiltration.

7 Maintenance Routines You Should Be Doing

To ensure the optimal performance and longevity of your commercial roof, incorporate the following maintenance routines into your schedule:

1) Regular Inspections:

Conduct thorough inspections of your roof at least twice a year, ideally in the spring and fall, to identify any signs of damage, wear, or deterioration.

2) Clear Debris:

Remove debris such as leaves, branches, and dirt from the roof surface and gutters regularly to prevent water pooling and drainage issues.

3) Check Seals and Flashings:

Inspect roof seals, flashings, and caulking around penetrations (vents, pipes, chimneys) for signs of wear, cracks, or gaps, and repair or replace as needed.

4) Trim Vegetation:

Keep vegetation trimmed away from the roof to prevent damage from overhanging branches and minimize the risk of mold and mildew growth.

5) Clean Drains and Scuppers:

Ensure that roof drains, scuppers, and downspouts are clear of debris to facilitate proper water drainage and prevent ponding.

6) Test Waterproofing:

Periodically test the waterproofing integrity of your roof through methods like flood testing or infrared scanning to detect hidden leaks and weaknesses.

7) Maintain HVAC Systems:

Inspect and maintain HVAC units, exhaust fans, and other rooftop equipment to prevent leaks or damage to the roof membrane.

How Often Should You Perform Commercial Roof Maintenance

The frequency of commercial roof maintenance depends on various factors, including the roof type, age, climate, and environmental conditions. As a general guideline:

  • Conduct visual inspections at least twice a year, preferably in the spring and fall, to catch any issues before they worsen.
  • Schedule professional inspections annually or after severe weather events such as storms or hail.
  • Perform routine maintenance tasks, such as debris removal and gutter cleaning, quarterly or as needed, especially after heavy rainfall or high winds.

Common Signs of Commercial Roof Damage

Recognizing the early warning signs of roof damage can help you address issues promptly and prevent further deterioration. Look out for the following indicators:

  • Leaks or Water Stains: Water infiltration, visible stains on interior ceilings or walls, or damp spots indicate roof leaks and require immediate attention.
  • Blisters or Bubbling: Blisters, bubbles, or wrinkles on the roof surface may signify moisture trapped beneath the membrane, compromising its integrity.
  • Cracks or Tears: Inspect the roof membrane for cracks, splits, tears, or punctures, which can allow water to penetrate and cause extensive damage.
  • Ponding Water: Standing water or ponding on the roof surface for more than 48 hours indicates poor drainage and potential structural issues.
  • Mold or Mildew Growth: Presence of mold, mildew, or algae on the roof surface or in interior spaces suggests excess moisture and poor ventilation.
  • Damaged Flashings: Loose, damaged, or missing flashings around roof penetrations are vulnerable points for water intrusion and should be repaired promptly.
  • Deteriorating Roofing Materials: Signs of aging, deterioration, or granule loss on asphalt shingles, membrane cracks on flat roofs, or corrosion on metal roofs signal the need for repairs or replacement.

When to Call a Professional for Help

While regular maintenance can address many roof issues, some situations require professional expertise and intervention. Consider seeking professional assistance if you encounter any of the following scenarios:

Extensive Damage:

If your roof sustains significant damage from severe weather, fire, or vandalism, contact a professional roofing contractor to assess the extent of the damage and recommend repairs or replacement.

Complex Repairs:

Repairs involving structural issues, large-scale leaks, or intricate roofing systems should be handled by experienced professionals with the necessary skills and equipment.

Roof Replacement:

When your commercial roof reaches the end of its lifespan or suffers irreparable damage, consult with roofing experts to explore replacement options tailored to your budget and business needs.

Safety Concerns:

Roof work can be hazardous, especially on multi-story buildings or steep slopes. Entrust safety-critical tasks to trained professionals equipped with proper safety gear and protocols.

Warranty Compliance:

If your roof is under warranty, adhere to the manufacturer’s maintenance requirements and enlist certified roofing contractors for inspections, repairs, and maintenance to preserve warranty coverage.
