Dangers of Leaking TPO Roofs for Commercial Buildings

Jen Woslager • December 4, 2024
As a business owner in Seattle, WA, you know that maintaining a safe and functional building is key to providing a comfortable environment for employees, customers, and tenants. One crucial component often overlooked until it's too late is your commercial roof. Particularly with TPO (Thermoplastic Olefin) roofing, a popular material for commercial buildings, leaks can develop over time, leading to significant damage if not addressed promptly.

At Riverside Roofing LLC, we specialize in TPO roof repairs and replacements, ensuring your commercial roof remains in top shape. In this blog, we’ll explain the potential dangers of a leaky TPO roof and why early detection is critical to preserving the integrity of your property.

What is TPO Roofing?
TPO is a single-ply membrane roofing material commonly used in commercial buildings due to its durability, energy efficiency, and cost-effectiveness. It's designed to reflect UV rays, helping keep your building cool and reducing energy costs. TPO roofing is known for being lightweight, flexible, and resistant to weathering, making it an excellent choice for commercial properties in Seattle’s often wet and rainy climate.

However, despite its advantages, TPO roofing can be susceptible to issues like any other material. Over time, improper maintenance, wear and tear, or extreme weather conditions can lead to leaks in the system.

The Dangers of a Leaky TPO Roof
Even a small leak in your TPO roof can lead to serious issues. Here’s why it’s essential to fix roof leaks promptly:

1. Water Damage to Building Structure
When water infiltrates a commercial building, it can cause significant damage to the building's structure. Leaks in your TPO roof allow water to seep into your walls, ceilings, and floors. Over time, this can weaken the integrity of the structure, causing wood rot, rust, and potentially compromising load-bearing walls.

• Ceiling and Wall Stains: One of the most common signs of a leak is water stains on the ceiling or walls. These stains indicate trapped moisture, which could be affecting the building’s framework and insulation.

• Structural Integrity: Prolonged exposure to water can damage the building’s framing, drywall, and flooring, leading to costly repairs and potentially dangerous structural issues.

2. Mold and Mildew Growth
Moisture from a leaking roof creates the ideal conditions for mold and mildew to thrive. In commercial spaces, mold can not only damage the property but also pose significant health risks to employees or tenants. Mold exposure can cause respiratory issues, allergies, and other health problems.

• Health Risks: Mold can trigger asthma, allergic reactions, and other respiratory issues, creating an unhealthy environment for those inside the building.

• Hidden Mold Growth: Mold doesn’t always appear immediately. It can grow behind walls, under insulation, or on ceiling tiles, making it even harder to spot early on. By the time it's visible, the damage could be significant.

3. Damage to Insulation
A leaky TPO roof can also cause your building's insulation to become wet and ineffective. This can affect the building's overall energy efficiency. Insulation is designed to help maintain consistent temperatures, and when it's compromised by water, your HVAC system will work harder to keep the space comfortable, leading to higher energy costs.

• Increased Energy Costs: Wet insulation loses its ability to regulate temperature, which means your heating and cooling systems will need to work overtime, driving up utility bills.

• Inefficient Heating and Cooling: If your insulation is damaged, you may notice drafts or inconsistent temperatures within your commercial building.

4. Pest Infestation
Leaks provide a perfect entry point for pests such as rodents, insects, and birds. Once they gain access to your building through the roof, they can cause additional damage by chewing through wires, insulation, or structural elements. Pests can also spread disease, further jeopardizing the health and safety of your building.

• Electrical Hazards: Rodents and other pests that chew through wires can create serious electrical hazards, potentially leading to fires.

• Property Damage: Beyond causing damage to the roof, pests can invade your office spaces, causing a mess and requiring costly pest control services.

5. Decreased Property Value
A leaking roof doesn’t just lead to immediate damage—it can also lower the value of your property. If a potential buyer or tenant sees signs of roof damage, water stains, or mold, they may hesitate to invest in the building, leading to decreased market value.

• Resale or Lease Issues: If you're planning to sell or lease your commercial property, a leaky roof can be a major red flag for prospective buyers or tenants. The cost of repairs can deter potential deals or reduce the asking price.

• Long-Term Investment Losses: Neglecting a roof leak can cost you much more in the long run when it reduces your property’s value.

What to Look for with TPO Roof Leaks
Here are some signs that your TPO roof may be leaking:

• Water Stains: Look for brown, wet spots on your ceiling or walls.

• Sagging Roof Deck: A sagging roof deck can indicate trapped water or severe leaks.

• Mold and Mildew: Musty smells or visible mold growth in the attic or on walls are signs of water infiltration.

• Missing or Damaged Flashing: Flashing around roof vents, HVAC systems, and chimneys may become damaged or detached, leading to leaks.

• Pooled Water: If you notice standing water on the roof, it could indicate that the roof’s drainage system is blocked or damaged.
