Common Roof Deck Waterproofing Problems and How to Address Them

Insights from EVERDRY PH Waterproofing Experts

Roof decks are a valuable addition to any building, offering extra usable space and protecting the structure below. But because they’re exposed to the elements year-round, roof decks are prone to certain problems. For property owners and administrators, knowing these common issues—and how to handle them—can save you time, money, and headaches.

Here are the most frequent roof deck waterproofing problems and practical tips on addressing them.

Roof Deck Waterproofing Problems

1. Water Leaks and Ponding

The Problem: Water leakage is one of the leading complaints with roof decks. Poor drainage systems or improper slopes often cause water to collect in pools. Over time, this standing water can penetrate the surface, damaging materials and the structure below.

How to Fix It:

• Make sure your roof deck is designed with adequate slope and drainage.

• Treat all water pondings or puddlings.

• Regularly clean drains to prevent blockages.

2. Cracking and Surface Deterioration

The Problem: Temperature fluctuations, heavy usage, and natural aging can cause cracks in your roof deck’s surface. Left untreated, these cracks can allow water to seep in, leading to more extensive damage to the structure.

How to Fix It:

• Small cracks should be sealed with the right repair materials. For larger structural cracks, always consult an expert.

3. Failing Waterproofing Systems

The Problem: The waterproofing layer, whether cold-applied or hot-applied, on roof decks can deteriorate due to UV exposure, weather changes, and aging. A compromised system leaves the deck vulnerable to leaks and water infiltration.

How to Fix It:

• Choose UV-stable materials or cover them with protective topping.

• Schedule regular inspections to assess the condition of your waterproofing.

• Reapply or upgrade your waterproofing system as needed.

4. Damage from Heat and UV Exposure

The Problem: Prolonged exposure to intense heat and UV radiation can cause materials to degrade, fade, or crack. These issues not only affect the aesthetics of your roof deck but also its functionality.

How to Fix It:

• Use reflective coatings to reduce heat absorption and prevent UV-related damage.

5. Poor Installation Practices

The Problem: Improper construction, including substandard materials or installation techniques, can lead to uneven surfaces, insufficient drainage, and early deterioration.

How to Fix It:

• Make sure you understand and execute the correct methodology for your building's needs.

• Engage with experienced professionals for all roof deck projects.

  
  

6. Neglected Maintenance

The Problem: Roof decks require regular maintenance, but it’s easy for small issues like clogged drains or minor cracks to go unnoticed—until they become major problems.

How to Fix It:

• Establish a routine inspection schedule to identify and address problems early.
