This article guides you through six of the most common commercial re-roofing issues in Texas, explains why they occur, and provides solutions to address or prevent them. Whether you’re planning a new roofing project or already dealing with roof leaks, understanding these challenges now can help you make smarter decisions and save time, money, and frustration later.
1. Poor Roof Drainage Leading to Ponding Water
The Problem:
One of the biggest problems with commercial roofs in Texas, especially flat or low-slope roofs, is poor drainage. When rainwater doesn’t drain properly, it starts to pool. These puddles (called “ponding water”) seem harmless at first, but over time, they weaken roofing materials, lead to mold growth, and cause leaks that damage insulation, ceilings, and even business operations.
Why It Happens:
- Clogged or undersized drains
- Poor initial design
- Inadequate slope
- Settling of the roof deck
- Debris buildup after Texas storms
The Solution:
The key is preventive design and regular maintenance. During re-roofing, make sure your contractor builds in a proper slope—even a slight 1/4 inch per foot can dramatically improve drainage. Install more or larger drains where needed. After re-roofing, schedule regular cleanings to remove debris, leaves, and dirt from drainage systems, especially after storms. Adding tapered insulation under the roof membrane can also help guide water to drains.
2. Choosing the Wrong Roofing Materials for Texas Weather
The Problem:
Many commercial roofs in Texas fail early simply because they’re built with the wrong materials. Texas sees extreme heat, sudden cold snaps, UV exposure, heavy rain, and high winds—conditions that not every roofing material can handle.
Why It Happens:
- Focus on upfront cost instead of long-term durability
- Not accounting for UV damage and thermal movement
- Use of materials designed for northern climates
- Lack of local contractor experience
The Solution:
Select roofing materials based on Texas-specific performance, not just price. Thermoplastic polyolefin (TPO) and PVC membranes are popular in Texas for their heat reflectivity and UV resistance. Metal roofs with proper insulation can also perform well. Consult a local, experienced roofer who understands regional weather demands and material behavior in extreme heat.
3. Improper Roof Installation by Inexperienced Contractors
The Problem:
Even the best roofing materials will fail if installed incorrectly. In Texas, this is one of the leading causes of commercial roofing problems. A rushed or sloppy installation can lead to leaks, poor insulation, premature wear, and costly repairs within just a few years.
Why It Happens:
- Unqualified or undertrained crews
- Lack of attention to detail in sealing and flashing
- Poor surface preparation
- Contractors unfamiliar with building codes
The Solution:
Choose your roofing contractor carefully. Don’t just go with the lowest bid. Look for licensed, bonded, and insured contractors with solid local experience and a track record of quality work. Ask for references, review warranties, and make sure the team is certified to install the materials you’ve chosen. The right contractor will ensure proper flashing, membrane overlaps, fastener spacing, and sealant application, all of which extend roof life.
4. Ignoring Existing Roof Damage Before Re-Roofing
The Problem:
A common mistake during commercial re-roofing in Texas is covering up old problems instead of fixing them. Hidden water damage, rotted decking, mold, or insect infestations under the old roof can continue causing problems if they’re not addressed before installing the new roof.
Why It Happens:
- Pressure to stay on budget or meet deadlines
- Lack of thorough inspection before re-roofing
- Inexperienced contractors skipping steps
- Building owners are unaware of the underlying issues
The Solution:
Always start with a full roof inspection. A reputable roofer will take core samples, check for moisture under the membrane, and inspect the roof deck for rot or weakness. If there’s existing damage, it needs to be repaired before any new materials go on. Re-roofing over hidden issues only delays bigger, more expensive problems down the line.
5. Inadequate Ventilation and Insulation
The Problem:
Texas is hot—scorching hot in the summer. Without proper ventilation and insulation, commercial roofs trap heat, making indoor temperatures unbearable and causing energy bills to spike. Long-term, this heat stress also causes premature roof failure.
Why It Happens:
- Lack of focus on energy efficiency
- Improper vent placement
- Using the wrong type or thickness of insulation
- Overlooking attic or plenum conditions
The Solution:
During re-roofing, take the opportunity to upgrade your ventilation and insulation systems. Use high-quality rigid foam insulation or spray polyurethane foam to create a strong thermal barrier. Add ridge vents, soffit vents, or mechanical ventilators, depending on your building’s structure. Not only will this protect your roof from heat damage, but it will also improve indoor comfort and reduce cooling costs.
6. Skipping Permits and Code Compliance
The Problem:
Some building owners or contractors try to save time or money by skipping permits or bending building codes. In Texas, that’s a risky move. Non-compliant roofs can lead to fines, delays, insurance problems, or even a forced tear-off and replacement.
Why It Happens:
- Cutting corners to reduce costs
- Contractors unfamiliar with local codes
- Fast-track timelines for retail or warehouse spaces
- Lack of due diligence by property managers
The Solution:
Always pull the proper permits and work with a contractor familiar with Texas building codes, especially those related to wind uplift, fire resistance, drainage, and insulation. Roofers should stay updated with city, county, and statewide codes, particularly in storm-prone areas like Houston, Dallas, and coastal regions. A code-compliant roof keeps your building safe, insurable, and marketable.
Final Thoughts: Preventing Roofing Headaches in Texas
Commercial re-roofing in Texas comes with challenges, but with the right planning and expert help, these challenges don’t have to turn into disasters. The key is to understand the risks upfront, choose materials and contractors wisely, and never skip steps during the process. Proper drainage, quality materials, code compliance, and a focus on ventilation and insulation will all extend your roof’s life and improve your building’s energy performance.
