Petersen and Dean Solar Roofing: A 20-Year Contractor's Honest Guide for Homeowners

For over two decades, I have worked on thousands of roofs across Texas. I have installed, repaired, and replaced roofs after every major storm. I hold certifications from GAF, CertainTeed, and the NRCA. This experience gives me a unique perspective on roofing systems. Today, I want to share my knowledge about Petersen and Dean Solar. This article exists because homeowners face a confusing choice. Should you add solar panels to your roof? Is it worth the investment? How do you choose the right contractor? I will answer these questions clearly. I will save you time and prevent costly mistakes. My goal is to provide honest, practical advice you can trust.

The information here comes from real projects. I have reviewed Petersen and Dean's work for customers. I have studied their materials and installation methods. I compared their offerings with industry standards from NRCA and manufacturer guidelines. I also referenced Texas building codes and insurance requirements. My methodology is simple. I look at what works in the field. I see what lasts through Texas heat and hail. I listen to what homeowners actually need. This guide combines that real-world experience. It will help you make an informed decision about your roof and solar power.

Understanding Petersen and Dean: Company Profile and Services

Petersen and Dean is a well-known roofing contractor. They operate primarily in Texas and surrounding states. The company has been in business for many years. They specialize in both roofing and solar panel installation. This dual focus is their main selling point. They offer to handle your entire roof and solar project. This can be convenient for homeowners. You deal with one company instead of two. However, it is crucial to understand their scope. Are they roofing experts who added solar? Or are they solar experts who added roofing? The answer affects the quality of your installation.

Core Services and Specializations

Petersen and Dean provide several key services. Their primary offering is roof replacement. They work with common materials like asphalt shingles and metal. They also handle storm damage repair and insurance claims. Their solar division installs photovoltaic (PV) panels. These panels convert sunlight into electricity for your home. The company often promotes bundled packages. They suggest replacing your roof and adding solar simultaneously. This approach has logical benefits. A new roof ensures a solid base for solar mounts. It avoids removing panels later for roof repairs.

From a contractor's view, bundling makes sense. But only if both services are executed perfectly. A roof must last 20-30 years. Solar panels have a similar lifespan. The installation must protect your roof's warranty. The solar attachment must not cause leaks. Petersen and Dean use their own crews for both trades. This is different from some companies that subcontract. Using in-house teams can improve coordination. It should lead to better accountability. However, the skill level of each crew is vital. A master roofer is not automatically a master solar installer. Homeowners must verify certifications in both fields.

The Technical Reality: Roofing and Solar Integration

Combining a new roof with solar is a technical challenge. It requires careful planning and expert execution. The roof is your home's first defense against weather. Solar panels add weight, wind uplift forces, and penetration points. Every hole drilled for a mounting bracket is a potential leak. A proper installation follows strict protocols. It must comply with the International Building Code (IBC) and local amendments. In Texas, wind resistance is critical. Mounting systems must withstand high winds common in our region.

Mounting Systems and Waterproofing

The method of attaching panels to the roof is paramount. There are two main types: penetrative and non-penetrative. Penetrative systems use lag bolts that go through the roof deck. These require flawless flashing and sealing. Non-penetrative systems use weighted ballasts or clamp onto seams. They are less common on steep shingle roofs. Petersen and Dean typically use rail-based penetrative systems. They attach aluminum rails to the roof with bolts. Panels then clip onto these rails. The quality of the flashing sealant is everything. I recommend using manufacturer-approved flashing kits. For example, IKO and GAF have specific guidelines for solar attachments.

A critical step is integrating the solar warranty with the roof warranty. If a solar install causes a leak, who pays? A roofer might blame the solar installer. The solar installer might blame the roofer. Using one company like Petersen and Dean should eliminate this blame game. In theory, they own the entire system's performance. You must get this guarantee in writing. The contract should state they warranty the roof against leaks from their solar installation. It should cover labor and materials for the full warranty period. Do not accept vague language. Demand specific terms.

Cost Analysis: Real Project Numbers and Financing

Cost is the biggest concern for most homeowners. A roof replacement plus solar is a major investment. Let's break down realistic numbers based on Texas projects. A typical 2,000-square-foot roof replacement with quality architectural shingles costs $12,000 to $20,000. A solar system for that home might be 8-10 kW. That system could cost $20,000 to $30,000 before incentives. The bundled price from Petersen and Dean may offer a discount. However, you must compare itemized quotes. Get separate bids for the roof and the solar. Then compare the bundled price.

Understanding Financing and Incentives

Petersen and Dean often promote financing options. They may offer loans or work with third-party lenders. Be very careful with solar leases or Power Purchase Agreements (PPAs). These are common in solar sales. You do not own the panels. You pay for the electricity they produce. This can complicate selling your home. It also may not provide the best long-term savings. The federal solar tax credit is a major incentive. As of 2025, it is 30% of the system cost. This credit applies to the solar portion only, not the roof. You must have sufficient tax liability to claim it.

Always read the fine print on financing. What is the interest rate? Is it a secured loan (using your home as collateral) or unsecured? What is the total repayment amount? I have seen homeowners focus only on the monthly payment. They ignore the total cost over 20 years. That is a mistake. Use the U.S. Department of Energy's calculators to estimate your solar savings. Input your actual electricity usage. Be skeptical of overly optimistic savings projections. Texas sun is great for solar. But your roof's orientation and shade matter greatly.

Material Selection: Roofing Under Solar Panels

The choice of roofing material is more important with solar. Once panels are installed, the roof is mostly hidden. It is also harder to repair. Therefore, you must choose a durable, long-lasting product. I recommend premium architectural asphalt shingles or metal roofing. These materials have longer warranties and better wind ratings. They can handle the thermal changes caused by panels. Panels create a gap above the roof. This space can get hot and affect shingles. High-quality shingles withstand this better.

Comparing Shingle Types and Lifespan

Standard 3-tab shingles are not ideal for solar. They have a shorter lifespan (15-20 years). Solar panels last 25+ years. You do not want to remove panels to replace worn-out shingles. Architectural shingles last 30 years or more. They are thicker and more durable. Brands like CertainTeed Landmark or GAF Timberline are excellent choices. Metal roofs are the best partner for solar. They last 40-70 years. Solar mounts can attach to the seams without penetrating the panels. This reduces leak risk. A standing seam metal roof is the premium option. It is more expensive upfront but offers the best longevity.

Discuss color with your contractor. Lighter roof colors reflect heat. This keeps your attic cooler. However, solar panels will cover much of the roof. The color's impact is reduced. Focus on quality and warranty over color. Ensure the shingle manufacturer's warranty is not voided by solar installation. Some manufacturers require specific attachment methods. Petersen and Dean should provide documentation of compliance. Ask for it. Keep it with your home records.

The Installation Process: What Should Happen on Your Roof

A proper installation follows a meticulous sequence. First, the old roof is removed down to the decking. The decking is inspected for rot or damage. Any bad wood is replaced. Then, new underlayment is installed. This is a water-resistant barrier. It is your secondary defense against leaks. High-quality synthetic underlayment is best. Next, the new shingles or metal panels are installed. The roofers must complete this before solar installation begins. The roof must be 100% finished and inspected.

Solar Installation and Critical Inspection Points

After the roof is done, the solar crew marks the rafter locations. They use a stud finder or blueprints. Mounting feet are placed directly over rafters. This provides solid structural support. They do not attach to just the decking. Each foot gets a layer of sealant. Then a metal flashing is placed over it. More sealant is applied. Finally, the lag bolt is driven through the flashing into the rafter. The rail is attached to the feet. This process is repeated for every mount. Homeowners should watch for sealant application. It should be generous and neat. There should be no gaps.

Before panels go up, request a mid-installation inspection. Walk on the roof with the foreman. Look at each flashing. Take photos. Ensure everything looks clean and sealed. Once you are satisfied, the panels can be installed. The electrical work is then connected to your main panel. A final inspection by the city or county is required. They will check the electrical and structural connections. Do not make final payment until this inspection passes. Keep all permits and inspection certificates.

Practical Homeowner Tips From Real Projects

Based on my experience, here is my best advice. Get everything in writing. The quote, the warranty, the timeline. Verbal promises are worthless. Check licenses and insurance. Petersen and Dean should hold a Texas Roofing Contractor license. They should also have general liability and workers' compensation insurance. Ask for certificate copies. Contact your home insurance provider. Tell them you are adding solar. Ensure your policy covers the system. Some policies require a rider for solar panels. Understand how it affects your roof's wind/hail coverage.

• Get Multiple Bids: Always get at least three quotes. Compare Petersen and Dean's offer with a dedicated roofer and a dedicated solar company.
• Check References: Ask for addresses of local projects completed 2-3 years ago. Drive by and look at them. If possible, talk to the homeowners.
• Review the Contract Thoroughly: The contract should list all materials by brand, model, and color. It should include start and completion dates. It must have a detailed payment schedule.
• Plan for Tree Trimming: Solar needs sun. You may need to trim or remove trees. Factor this cost and any HOA approvals into your plan.
• Monitor Your System: Once installed, use the monitoring app. Watch your energy production. A sudden drop could indicate a panel issue or shading problem.

Frequently Asked Questions (FAQ)

Will solar panels damage my new roof?

Properly installed panels should not damage your roof. The key is proper installation by certified professionals. The mounting system must be flashed and sealed correctly. This prevents water intrusion. A quality installer like Petersen and Dean should guarantee their work against leaks. Always get this warranty in writing.

How long does the entire project take?

A roof replacement for an average home takes 2-3 days. The solar installation adds 2-4 more days. However, permitting and utility interconnection can take weeks. The total timeline from signing a contract to system activation is often 6-10 weeks. Weather delays can also extend this timeframe.

What happens if my roof needs repair under the panels?

This is a major consideration. If a shingle is damaged or a leak occurs, the panels must be removed. This adds significant cost. This is why using a single provider is advantageous. Petersen and Dean would handle both the panel removal and roof repair. Ensure your contract outlines this process and any associated costs.

Does a solar roof increase my home's value?

Yes, studies show solar panels can increase home value. The Appraisal Journal indicates a increase of about $20 for every $1 saved on annual electricity. A new roof also adds value. Together, they are a strong home improvement investment, especially in sunny Texas.

Can I install solar on an older roof?

It is not recommended. Solar panels have a 25+ year lifespan. If your roof is over 10 years old, you may need to replace it soon. Removing panels for a roof replacement costs thousands of dollars. It is more cost-effective to replace the roof first or bundle the projects together.

What about hail damage? Are solar panels durable?

Modern solar panels are tested to withstand hail. Most are rated for 1-inch hail at 50+ mph. However, a severe hailstorm can still damage them. Check the panel's warranty for hail coverage. Also, review your homeowner's insurance policy. Ensure both your roof and solar panels are covered for storm damage common in Texas.

Who handles maintenance and repairs?

You should receive a maintenance guide. Solar panels require little maintenance—mainly keeping them clean. The inverter may need replacement after 10-15 years. Understand what Petersen and Dean's service package includes. Know the warranty period for labor versus parts. Keep all contact information handy.

Real Project Case Study and Outcomes

I consulted on a project in Kingwood, Texas. The homeowners used Petersen and Dean in 2022. Their roof was 20 years old and had storm damage. They wanted solar to reduce high summer electric bills. Petersen and Dean proposed a bundle: a GAF Timberline HDZ roof and a 9.6 kW solar system. The total quote was $48,500. They financed it with a 20-year loan. The process took 9 weeks from sign-up to activation. The roof crew was efficient. The solar crew was neat and communicative.

Two years later, the outcome is positive. The roof looks great with no issues. The solar system produces about 1,200 kWh per month in summer. This covers about 85% of their usage. Their electric bill dropped from $250 to about $40 per month. They had one minor issue: a monitoring app glitch. Petersen and Dean's service team resolved it within a week. The homeowners are satisfied. Their key advice was to be present during the flashing installation. They took photos which gave them peace of mind.

Industry Statistics and Data

Understanding broader trends helps. According to the Solar Energy Industries Association (SEIA), Texas is the #2 state for solar capacity. Residential solar installations grew 35% in Texas last year. The average cost per watt for residential solar in Texas is about $2.75. Roofing costs vary by material. Asphalt shingles account for about 80% of the residential market. Metal roofing is growing at 5% annually due to its durability. Combining roof and solar projects can increase customer satisfaction by 25%, according to contractor surveys. This is due to single-point accountability.

Step-by-Step Guide to Evaluating Your Project

1. Assess Your Roof: Determine its age, material, and condition. If it has less than 10 years of life left, plan for replacement.
2. Analyze Your Energy Use: Get 12 months of electric bills. Calculate your average monthly kWh usage. This sizes your solar system.
3. Get Multiple Quotes: Obtain 3 detailed bids. One from a bundled provider like Petersen and Dean. One from a roofing specialist. One from a solar specialist.
4. Check Credentials: Verify licenses, insurance, and manufacturer certifications (like GAF Master Elite). Check the BBB for complaints.
5. Review Financing: Compare cash price versus loan options. Calculate the total interest paid. Understand the federal tax credit process.
6. Finalize Contract: Ensure all details are in writing. Materials, warranties, timeline, payment schedule, and cleanup duties.
7. Monitor Installation: Be present for key stages. Take photos. Conduct your own mid-point inspection before panels are mounted.
8. Final Inspection and Payment: Do not make final payment until the system passes all municipal inspections and is producing power.

Conclusion: Making an Informed Decision

Choosing Petersen and Dean for a solar roofing project is a significant decision. Their bundled approach offers convenience and potential accountability benefits. However, it requires thorough due diligence on your part. You must verify their expertise in both roofing and solar as separate trades. You must scrutinize the contract and warranties. You must understand the full financial commitment. A new roof with solar is a long-term investment in your home's comfort, efficiency, and value.

Use this guide as a checklist. Ask the hard questions. Demand clear answers. Your roof is too important to leave to chance. If done right, this project can provide decades of reliable shelter and clean energy. Your next step is to gather your energy bills and get a roof inspection. Then, start the quoting process with confidence. You now have the knowledge to navigate it successfully. Remember, a good contractor welcomes informed customers. They will appreciate your questions and provide clear evidence of their quality work.
