Your commercial roof plays a crucial role in protecting your property from the elements. Hidden roof issues can easily go unnoticed until they escalate into expensive problems. By identifying early signs of damage or wear, you can prevent costly repairs and extend the lifespan of your roof.
In this blog, we’ll explore how to spot hidden roof issues, particularly with roof membranes, and why regular inspections are essential for commercial properties.
1. Inspect for Roof Membrane Damage
The roof membrane is one of the most important components of a commercial roof. Over time, exposure to harsh weather conditions and UV rays can cause damage, leading to hidden roof issues. Here are some signs to look for:
- Tears: Tears in the membrane can lead to water infiltration and deterioration of the underlying layers.
- Blistering or Bubbling: This occurs when moisture gets trapped beneath the membrane. Blisters or bubbles can weaken the roof structure and lead to leaks.
- Pooling Water: Stagnant water on the roof may indicate poor drainage or an issue with the roof not directing water away effectively.
2. Check for Water Damage Inside the Building
Water infiltration is one of the most common and damaging hidden roof issues. Even if you don’t see visible leaks, moisture can still enter through minor tears or gaps. Look out for:
- Stains on Ceilings and Walls: Water stains inside your building can indicate hidden roof issues that allow moisture to penetrate.
- Mold or Mildew: If you notice mold growth, it could be a sign that water is entering the building through a damaged roof membrane.
- Damp or Wet Insulation: Moisture trapped in insulation can compromise the roof’s ability to regulate temperature and lead to mold growth.
3. Look for Flashing and Sealant Issues
Flashing around roof penetrations, such as vents, pipes, or skylights, is designed to prevent water from entering. Over time, the flashing and sealant can degrade, leading to hidden roof issues. Watch for:
- Cracked or Missing Flashing: Small gaps or cracks in the flashing can allow water to seep into the roof structure.
- Worn or Deteriorated Sealant: Sealant around flashing or other roof joints can wear away over time, creating entry points for water.
- Loose Flashing: If the flashing isn’t tightly secured, it can lift during strong winds, allowing water to infiltrate beneath the roof membrane.
4. Monitor Roof Drainage and Gutters
Proper drainage is crucial for preventing water damage to your commercial roof. Clogged gutters or poor drainage can lead to water pooling on the roof, increasing the risk of hidden roof issues. Check for:
- Clogged or Blocked Gutters: Debris buildup in gutters can prevent water from flowing off the roof, leading to standing water and membrane damage.
- Damaged Drainage Pipes: Look for cracks or leaks in drainage pipes, which can cause water to accumulate on the roof.
- Pooling Water: Persistent standing water on your roof is a clear sign of poor drainage and potential membrane failure.
5. Examine Roof Penetrations and Vents
Roof penetrations, including vents, exhaust pipes, and HVAC units, are vulnerable points where hidden roof issues may occur. Inspect these areas for:
- Cracks or Gaps: Any cracks around the penetrations can lead to water entering the roof structure.
- Deteriorated Gaskets or Seals: The gaskets or seals around penetrations can wear out over time, allowing water to seep through.
- Loose or Shifting Equipment: Equipment such as HVAC units or vents that are not properly secured can create openings for water to enter the roof.
6. Inspect for Ponding Water
Ponding water refers to areas where water collects and remains on the roof for an extended period. This is a serious issue, as stagnant water can lead to membrane damage, corrosion, and even structural weakening. To check for ponding water:
- Visual Inspection: After a rainstorm, inspect your roof for areas where water hasn’t drained off.
- Check for Debris: Leaves, twigs, or other debris can block drainage, causing water to pool in certain areas of the roof.
- Measure Water Depth: If water accumulates in low-lying areas, it may indicate issues with the slope or drainage system.
7. Monitor Roof Temperature and Ventilation
Proper ventilation is essential for maintaining the integrity of your roof. Poor ventilation can trap heat and moisture, which can lead to hidden roof issues like membrane degradation. To ensure your roof is well-ventilated:
- Check Ventilation Systems: Ensure that all vents are clear and functioning properly to allow for air circulation.
- Inspect for Moisture: Poor ventilation can result in excess moisture trapped within the roofing system, which can cause the membrane to deteriorate.
