When it’s time to address roofing concerns, some homeowners consider the "roof-over" method, where new shingles are laid directly over an existing roof. While this option may seem like a cost-effective and time-saving solution, it comes with significant drawbacks—especially in Texas cities like Houston and Austin, where weather conditions can be extreme.
At Martin Roofing and Solar, we don’t cut corners. That’s why we’ll never do a roof-over—we believe in doing things the right way to ensure the safety and longevity of your home. Here's why a roof-over may not be the best choice for your Texas home and why a full roof replacement is a superior investment.
What Is a Roof-Over?
A roof-over involves placing a new layer of shingles directly on top of an old one instead of removing the existing roof material creating two layers. Although it reduces upfront costs and installation time, this method isn’t always suitable, particularly in areas like Houston and Austin with their unique climates.
At Martin Roofing and Solar, we refuse to compromise on quality or your home's safety. A roof-over might seem like a quick fix, but we know that the risks far outweigh the benefits, which is why we only offer solutions that adhere to the highest standards.
1. Texas Weather Is Too Demanding
Heat in Houston and Austin
Texas summers can bring relentless heat, with temperatures often exceeding 100°F. The extra layer from a roof-over traps heat, intensifying the temperature inside your home and straining your HVAC system.
Humidity in Houston and Austin
Houston's high humidity creates ideal conditions for mold and moisture buildup. A roof-over can mask underlying water damage, leading to structural issues that are harder to detect until they become severe. For example, roof decking may begin to rot prematurely due to trapped water or humidity.
Wind and Storms
Both Austin and Houston experience strong winds, hail, and occasional hurricanes. A roof-over lacks the durability of a full replacement, making it more susceptible to damage during storms. Flying debris can penetrate the weaker structure, compromising your roof's ability to protect your home.
2. Structural Concerns with Roof-Overs
Added Weight
Roof shingles are heavy, and adding a second layer significantly increases the load on your home's structure. This extra weight may lead to sagging, leaks, or even collapse over time—particularly in older homes.
Hiding Existing Damage
A roof-over conceals the existing roof, making it impossible to inspect for hidden damage such as rotting wood, cracks, or improperly installed flashing. If undetected, these issues can worsen and require more extensive (and expensive) repairs later.
Limited Lifespan
The lifespan of a roof-over is typically shorter than that of a completely replaced roof. Over time, the added layers can warp, curl, or crack under the intense Texas sun, reducing your roof’s effectiveness.
3. Roof-Overs Are More Expensive Long-Term
While a roof-over might save money upfront, it’s actually the costlier option over time. Here’s why:
Shorter Lifespan Equals More Frequent Replacements: Roof-overs last maybe 10-15 years, compared to the 20-30 years of a full roof replacement. This means you’ll likely need another roof sooner, doubling the cost over time.
Higher Cost Per Year: Divide the initial cost of a roof-over by its shorter lifespan, and you’ll find the cost per year is much higher than a proper roof replacement.
Additional Repairs on the Next Replacement: Removing multiple layers of shingles during the next replacement will incur higher labor costs, further increasing your total expenses.
At Martin Roofing and Solar, we understand that cutting corners now can lead to costly issues down the road. That's why we never recommend a roof-over—it’s not worth the risks or expenses for Texas homeowners.
4. Code Compliance and Warranty Issues
Texas Building Codes
In some Texas counties, building codes prohibit more than two layers of shingles. A roof-over might violate these regulations, putting homeowners at risk of fines or requiring costly rework to comply.
Voided Warranties
Many roofing material manufacturers will void warranties if their products are used in a roof-over. Without a warranty, you’ll bear the full cost of repairs if the new layer fails.
5. Energy Efficiency and Ventilation Problems
Poor Insulation
The additional layer in a roof-over reduces ventilation, leading to inefficient heat dissipation. This not only increases cooling costs but also accelerates roof degradation.
Austin's Energy Codes
Austin places a strong emphasis on energy efficiency. A roof-over typically doesn’t meet modern energy codes or standards, meaning your home could fall short of eco-friendly benchmarks and increase your utility bills.
6. Reduced Curb Appeal and Home Value
Roof-overs often look bulky and uneven with multiple layers of shingles, detracting from your home’s curb appeal. Prospective buyers in competitive markets like Austin and Houston may be wary of a home with a roof-over, perceiving it as a sign of corner-cutting.
