As a commercial building owner in Texas, regular roof inspections are one of the most important steps you can take to protect your investment. Extreme heat, sudden storms, hail, and high winds are all common in the region, and your roof bears the brunt of it all. That’s why experts recommend a commercial roof inspection at least twice a year—every six months—to catch potential issues early and prevent costly damage down the road.
In this article, we’ll break down why semi-annual inspections are essential, what professional roofers check during an inspection, and what you should be looking out for in between visits.
Why Twice a Year?
Between spring hailstorms, intense summer heat, hurricane-season winds, and winter cold snaps, your roof endures multiple types of weather-related stress every year.
A six-month inspection schedule—typically in the spring and fall—allows you to:
- Catch storm damage before it worsens
- Extend the lifespan of your roofing system
- Address wear-and-tear before it leads to leaks
- Keep energy bills down by ensuring your roof is well-insulated and sealed
- Avoid disruption to tenants or businesses operating inside the building
- Make sure that you are compliant with your manufacturer and workmanship warranties.
If your building has older roofing materials, rooftop equipment like HVAC systems, or past leak history, more frequent inspections may be recommended.
What Happens During a Commercial Roof Inspection?
When you schedule a roof inspection with a professional roofing contractor like Rhino Roofers, they perform a comprehensive assessment of all roof-related components. Here’s what’s typically included in a thorough commercial roof inspection:
1. Visual Examination of the Roof Surface
Inspectors walk the entire roof to look for cracks, blisters, punctures, or wear. On single-ply systems like TPO or PVC, they check the condition of seams and membrane integrity. On SPF roofs, they’ll look at the condition of the coating layer.
2. Inspection of Flashings and Penetrations
Roof penetrations—such as vents, skylights, pipes, and HVAC units—are some of the most common sources of leaks. Inspectors will examine all these areas for separation, lifted flashing, deteriorated sealant, or visible gaps.
3. Drainage System Check
Good drainage is essential for flat or low-slope roofs. A roof inspection includes evaluating internal drains, scuppers, and downspouts for blockages, clogs, or standing water. Any evidence of ponding water is a red flag.
4. Perimeter and Edge Analysis
Roof edges, parapet walls, and perimeter flashing are vulnerable to wind uplift and sealant breakdown. Inspectors check these areas for cracking, loose metal, or signs of water infiltration.
5. Coating and Sealant Review
If your roof has a reflective or elastomeric coating, the inspector will assess its condition. Worn-out coatings or thin spots can compromise waterproofing and thermal performance. Recoating at the right time can add 10–20 years to your roof’s life.
6. Structural Observations
Although inspectors don’t usually access the internal roof deck, they look for sagging, uneven surfaces, or signs of movement that could indicate structural issues. They may also check for signs of moisture infiltration inside ceiling areas.
7. Photographic Documentation
Most professional roofers provide a photo report, so you have clear evidence of the roof’s condition, areas of concern, and recommended next steps.
What to Watch for Between Inspections
While licensed professionals handle semi-annual inspections, building owners and property managers can stay vigilant year-round by monitoring a few key indicators.
Here’s what to look out for between inspections:
Leaks or Water Intrusion
This is the most obvious sign of roof trouble. If tenants report ceiling stains, water near light fixtures, or musty odors after a storm, act quickly—even a small drip could point to a serious membrane or flashing issue.
Staining on Ceilings or Walls
Water stains might appear before active dripping occurs. Check utility rooms, restrooms, and upper-floor walls for discoloration or bubbling paint.
HVAC or Rooftop Service Work
If contractors have been on the roof for HVAC or satellite installations, inspect afterward. Tools, dropped screws, or even soft-soled shoes can damage a membrane. Ask your contractors to stay on walk paths and use protective pads if possible.
Standing Water
After rainfall, check for water that hasn’t drained within 48 hours. Ponding water accelerates material degradation and often leads to structural concerns. Poor drainage should be addressed immediately.
Membrane Damage
If you can safely access your roof (or have a maintenance team that can), look for visible cracks, holes, loose seams, or wear along rooftop walkways. Be cautious not to damage the surface while inspecting it.
Flashing Movement
Flashing around vents, pipes, or walls can shift during storms or settle with age. If you notice exposed edges or lifted corners, it may be time for resealing.
Additional Benefits of Routine Roof Inspections
Regular inspections don’t just help avoid leaks—they add value in other important ways:
- Insurance Claims: Post-storm inspection reports help support claims for weather-related damage.
- Warranty Compliance: Many commercial roof warranties require documentation of routine maintenance to remain valid.
- Budget Planning: Knowing the current condition of your roof helps you plan for recoating, patching, or full replacement years in advance.
- Tenant Confidence: If you lease the space, maintaining the roof shows tenants that you’re proactive about protecting their business operations.
