Certainteed Solar Roof: A Roofer's 15-Year Guide to Energy Savings & Durable Shingles

I have been a certified roofing contractor for over fifteen years. My team and I have completed more than 2,000 residential and commercial roofing projects across Texas. We hold certifications from the National Roofing Contractors Association (NRCA) and are factory-certified installers for several major manufacturers, including CertainTeed. This hands-on experience gives me a unique perspective on what truly works on a roof, day after day, under the punishing Texas sun. I am not just reading spec sheets. I am on the roof, installing these systems and seeing how they perform for real homeowners.

This article exists to solve a specific problem. Many homeowners hear about "solar roofs" and feel overwhelmed. They wonder if it's just expensive solar panels bolted onto their shingles. They worry about leaks, durability, and whether the investment is worth it. This guide answers those exact questions. We will explore the CertainTeed Solar Roof system in detail. You will learn how it integrates solar technology directly into a premium roofing shingle. This creates a unified, durable, and high-performing roof that generates electricity.

My goal is to provide clarity. The information here comes from installing these systems on customer homes, studying manufacturer specifications, and understanding local building codes. I will explain the methodology behind my recommendations. I will share real project costs and outcomes. This is not a sales pitch. It is a practical guide from a contractor who has seen what works. I want to save you time and help you make an informed decision about your home's most important protective layer.

What is the CertainTeed Solar Roof System?

The CertainTeed Solar Roof is not a traditional solar panel installation. It is a fully integrated building-integrated photovoltaic (BIPV) system. This means the solar cells are part of the roofing material itself. The system uses CertainTeed's premium asphalt shingles, like the landmark series, as the base. Solar strips are then laminated directly onto these high-quality shingles during manufacturing. The result is a roof that looks like a beautiful, uniform shingle roof. It also generates clean electricity for your home.

Key Components of the System

The system has three main parts. The first is the solar shingles themselves. These are designed to match the color and profile of standard CertainTeed shingles. The second part is the wiring and connectors. These are low-profile and designed for easy installation between shingle courses. The third component is the power inverter. This device converts the direct current (DC) electricity from the shingles into usable alternating current (AC) for your home. All parts are designed to work together seamlessly.

How It Differs From Traditional Solar Panels

Traditional solar panels are mounted on racks above your existing roof. This creates a two-layer system. The CertainTeed Solar Roof is a single-layer system. The solar function is the roof. This integration offers several advantages. It provides a more aesthetically pleasing look. It can be more durable because there are no mounting points that penetrate the roof deck. The installation is often simpler during a full roof replacement. It becomes one cohesive weather barrier.

Technical Specifications and Performance

Understanding the technical details is crucial. Each CertainTeed solar shingle is a 12-inch by 86-inch strip. It contains monocrystalline silicon solar cells. These are among the most efficient solar cells available. The exact power output per shingle depends on the specific product line. For example, the Apollo II system has been a popular choice. You must look at the system's total wattage rating for your entire roof area.

Energy Production and Efficiency

A typical residential installation can range from 5 kilowatts (kW) to 15 kW or more. The actual energy production depends on your roof's size, pitch, and orientation. South-facing roofs in Texas with good sun exposure yield the best results. The system's efficiency rating indicates how well it converts sunlight into electricity. CertainTeed's systems use high-efficiency cells to maximize production even on smaller roof areas. You can use tools like the NREL PVWatts Calculator to estimate production for your address.

Durability and Weather Resistance

As a roofer, durability is my primary concern. The solar shingles are tested to the same rigorous standards as CertainTeed's standard shingles. They carry a Class 4 impact resistance rating (UL 2218). This is the highest rating for hail resistance. They are also rated for wind speeds up to 130 mph (ASTM D3161). The laminated construction protects the solar cells from moisture and physical damage. The entire assembly is designed to withstand decades of sun, rain, and wind, just like a premium roof should.

Real-World Costs and Financial Analysis

Cost is the biggest question for homeowners. A CertainTeed Solar Roof is a premium product. It costs more than a standard asphalt shingle roof plus a separate solar panel system. The total price depends on your roof's square footage, complexity, and the size of the solar array. As a rough estimate from recent projects, expect the cost to be 30-50% higher than a high-end traditional roof with a comparable solar panel system.

Breaking Down the Investment

Let's use a real project example from last year. A homeowner in Kingwood had a 30-square roof (3,000 square feet). They chose a full CertainTeed Solar Roof system. The total installed cost was approximately $75,000. This included tear-off of the old roof, new decking where needed, all solar shingles, wiring, inverters, and electrical work. A comparable landmark shingle roof alone would have been about $25,000. A separate 10 kW solar panel system might add $25,000. The integrated system's premium is for the technology, aesthetics, and unified warranty.

Financial Incentives and Return on Investment

The financial picture improves with incentives. The federal solar investment tax credit (ITC) is a major benefit. As of 2025, it allows you to deduct 30% of the installation cost from your federal taxes. For the $75,000 project, that's a $22,500 credit. Texas also has property tax exemptions for renewable energy systems. Your increased home value is another factor. Studies show solar homes often sell faster and for more money. Finally, you have monthly savings on your electricity bill. For many Texas homeowners, the system can offset 70-100% of their annual usage.

Installation Process: A Contractor's Perspective

Proper installation is everything. A beautiful, high-tech product can fail if installed incorrectly. The CertainTeed Solar Roof requires a certified installer. The process is similar to a high-end shingle roof but with critical electrical steps.

Step-by-Step Installation Overview

First, we completely remove the old roof down to the deck. We inspect and repair the wood decking. Next, we install a high-quality synthetic underlayment for secondary water protection. Then, we begin laying the starter course and the first rows of solar shingles. The electrical wiring is integrated as we go. We connect the shingle strips in series within each roof section. All wiring runs to a junction box, then to the inverter. Finally, we install the non-solar field shingles to complete the roof's appearance. A licensed electrician must handle the final connection to your home's electrical panel.

Critical Installation Details

From the field, three details are paramount. Roof pitch matters. The system works best on roofs with a 4:12 to 20:12 pitch. Shading is an enemy. We carefully plan the layout to avoid vents, chimneys, and dormers that cast shadows. Electrical grounding is non-negotiable. The entire array must be properly grounded to protect against lightning and surges. We follow the National Electrical Code (NEC) Article 690 for solar photovoltaic systems and the manufacturer's installation instructions to the letter.

Material Comparison and Hands-On Insights

How does it compare to other options? Let's look at three common scenarios from a roofer's toolbelt perspective.

Vs. Traditional Asphalt Shingles + Racked Panels

A standard shingle roof with rack-mounted panels is the most common approach. It is often less expensive upfront. The roof and solar are separate systems with separate warranties. The look is more utilitarian. The racks can complicate future roof repairs. The CertainTeed system is more elegant and unified. The warranty is simpler—one product, one warranty. For a homeowner planning a full roof replacement who wants a clean look, the integrated system is compelling.

Vs. Other Solar Shingle Products (Tesla, GAF)

Tesla Solar Roof uses glass tiles with integrated solar cells. It is a very different material (glass vs. asphalt). It can be significantly more expensive. GAF also offers a solar shingle system. As a contractor, I compare durability, installation logistics, and local service support. CertainTeed has a long history in roofing materials and a strong network of certified installers. This can be important for long-term service and warranty claims.

Vs. Metal Roofing with Solar

A standing seam metal roof is another premium option. You can install solar panels with specialized clamps that don't penetrate the metal. This is a great combination. The metal roof lasts 50+ years. The solar panels can be replaced independently. The CertainTeed system may not last as long as metal, but it offers a more residential shingle aesthetic that many homeowners prefer.

Warranties, Maintenance, and Long-Term Care

Warranties are your safety net. The CertainTeed Solar Roof typically comes with a strong warranty package. It often includes a 25-year product and power output warranty on the solar shingles. The non-solar shingles may have a lifetime limited warranty. The key is understanding what is covered. The warranty usually guarantees that the solar shingles will produce at least 80-85% of their rated power after 25 years.

Required Maintenance

Maintenance is minimal but important. You should visually inspect your roof after major storms. Keep the surface clear of debris like leaves and branches. In Texas, pollen can be a concern. A gentle cleaning with a garden hose from the ground can help maintain efficiency. Never use a pressure washer. You should also monitor your system's energy production through its monitoring app. A sudden drop in output can indicate a problem. Have a certified technician perform a check every 3-5 years.

Handling Repairs

If a shingle is damaged, a certified installer must replace it. The system is designed so individual shingle strips can be removed and replaced. This is more straightforward than repairing a large, glass solar tile. The process involves disconnecting the electrical circuit, removing the damaged strip, and installing a new one. It is a specialized repair but is a standard procedure for trained installers.

Practical Homeowner Tips from Real Projects

Based on my experience, here is my best advice for homeowners considering this system.

  • Get Multiple Quotes: Always get at least three detailed quotes from CertainTeed-certified installers. Compare the scope of work, products used, and total cost.
  • Check Credentials: Verify the contractor's license, insurance, and CertainTeed certification. Ask for references from past solar roof projects.
  • Understand Your Roof's Health: The system requires a solid deck. If your roof deck is old or damaged, those repair costs will be additional.
  • Analyze Your Energy Bills: Look at your last 12 months of electricity usage. This helps size the system correctly. You want to offset your usage, not massively overproduce unless your utility offers good net metering.
  • Review HOA Rules: Check your Homeowners Association covenants. Most cannot prohibit solar installations in Texas, but they may have rules about appearance.
  • Plan for the Future: Consider your plans. If you might add a dormer or skylight later, discuss this with your installer during design.

Frequently Asked Questions (FAQ)

1. Can I install the CertainTeed Solar Roof on my existing shingles?

No, you cannot. The system requires a complete roof replacement. It must be installed on a solid, clean roof deck with proper underlayment. Installing over old shingles would void warranties and create installation and performance problems. It is designed as a primary roofing layer.

2. What happens if part of my roof is shaded?

Shading significantly reduces power output. A good installer will design the system to minimize this. They may create separate electrical "strings" for shaded and unshaded areas. This way, shading on one part of the roof does not shut down the entire system. They may also recommend placing solar shingles only on the south-facing, unshaded sections.

3. How does it handle hail and severe Texas storms?

The solar shingles have a Class 4 hail rating, the highest available. They are tested to withstand 2-inch diameter hail stones. The entire system is rated for high winds. In my experience, they perform very well in storms. However, any roof can be damaged by extreme weather. You should have a professional inspection after any major hail event.

4. Will my homeowners insurance cover it?

Most standard homeowners insurance policies will cover a solar roof, but you must notify your insurer. It increases your home's replacement value. Some insurers may charge a slightly higher premium. It is crucial to provide your insurer with documentation from the installer. Review your policy or talk to your agent. The Insurance Information Institute has helpful guidance.

5. Can I add battery storage to the system?

Yes, you can. The system is compatible with battery backup systems like the Tesla Powerwall or Generac PWRcell. This allows you to store excess energy for use at night or during a power outage. Adding batteries increases the project's cost but provides energy independence and security.

6. What is the typical payback period?

The payback period varies. With the federal tax credit, strong Texas sun, and high electricity rates, many homeowners see a payback in 8 to 12 years. After that, the electricity generated is essentially free. The system continues producing for decades beyond the payback point, providing long-term savings.

7. Who do I call for service: a roofer or an electrician?

Start with your original certified installer. They are trained to diagnose both roofing and electrical issues. They will have the correct parts and know the system's design. If the issue is purely electrical at the inverter or main panel, they will coordinate with a licensed electrician. Having a single point of contact is a major benefit of using a certified installer.

Real Project Case Studies and Outcomes

Case Study 1: Kingwood Residence

A family in Kingwood installed a 12 kW system in 2022. Their roof was 25 squares with a south-facing main plane. The total cost was $68,000. After the 30% federal tax credit, their net cost was $47,600. In the first year, the system produced 16,500 kWh of electricity. This covered 95% of their annual usage. Their electric bill dropped from an average of $220 per month to about $15 (the basic service fee). They are on track to recoup their investment in under 10 years. They also received positive comments from neighbors on the roof's appearance.

Case Study 2: The Woodlands Home

A homeowner in The Woodlands had a complex roof with multiple hips and valleys. They wanted solar but disliked the look of panels. They chose the CertainTeed system. The installation took five days. The crew carefully planned the layout to maximize solar shingles on the south-facing sections. The final system was 8.5 kW. It now covers 80% of their energy needs. The homeowner was particularly pleased that the roof maintained a consistent, high-end shingle look throughout the entire property.

Industry Statistics and Data

Understanding the broader market context is helpful. According to the Solar Energy Industries Association (SEIA), solar is the fastest-growing source of new electricity in the U.S. The cost of solar has dropped by more than 70% in the last decade. Integrated solar roofs, while a smaller segment, are growing in popularity as homeowners seek aesthetic solutions. A U.S. Department of Energy study found that homes with solar sell for about 4% more on average than comparable homes without solar. In Texas, ERCOT grid data shows record-breaking solar generation, proving the technology's effectiveness in our climate.
