Solar energy has rapidly become one of the most popular and effective ways for homeowners to reduce energy costs and minimize environmental impact. In New Jersey, many homeowners consider installing solar panels alongside roof replacements to maximize the benefits of both upgrades. However, misconceptions and myths about combining solar panels with your roof can create confusion and hesitation.

At GenSun Roofing, we help New Jersey homeowners separate fact from fiction. This article addresses the most common myths about installing solar panels with your roof and provides clear, accurate information to help you make informed decisions.

Myth 1: You Can Install Solar Panels on Any Roof, Regardless of Condition

One of the biggest misconceptions is that solar panels can be installed on any roof, no matter its age or condition. This is simply not true.

Fact: Solar panels have a lifespan of 25 to 30 years. Installing them on an old or damaged roof often means you’ll need to remove and reinstall the panels later to repair or replace the roof—resulting in extra costs and hassle.

At GenSun Roofing, we recommend a thorough roof inspection before solar installation. If your roof is near the end of its life or showing signs of wear—such as missing shingles, leaks, or structural damage—it’s best to replace or repair it before installing solar panels.

Myth 2: Solar Panels Will Damage Your Roof

Many homeowners worry that solar panel installation will harm their roof’s integrity or cause leaks.

Fact: When installed by professionals, solar panels do not damage your roof. In fact, panels can protect the roof areas they cover from harsh weather, reducing wear from sun, rain, and hail.

Our licensed installers at GenSun Roofing use industry-standard flashing and mounting systems designed to keep your roof watertight. Proper installation ensures no damage occurs and may even extend your roof’s lifespan.

Myth 3: Roof Replacement and Solar Installation Must Be Done Separately

Some believe roof replacement and solar panel installation are two completely separate projects that cannot be coordinated.

Fact: Coordinating roof replacement and solar installation is not only possible but highly recommended. Combining these projects saves time, reduces labor costs, and minimizes disruptions to your home.

GenSun Roofing specializes in seamless integration of roofing and solar services. We plan and execute both projects together, ensuring your new roof is solar-ready and your panels are installed efficiently.

Myth 4: Solar Panels Only Work on Certain Types of Roofs

There’s a misconception that solar panels can only be installed on asphalt shingle roofs.

Fact: While asphalt shingles are the most common roofing material compatible with solar panels, solar systems can be installed on various roof types, including metal, tile, slate, and flat roofs.

That said, some materials require specialized mounting systems or preparation. For example, slate and tile roofs need careful handling to avoid damage. At GenSun Roofing, we have experience working with diverse roofing materials and tailoring solar solutions accordingly.

Myth 5: Solar Panels Will Void My Roof Warranty

Many homeowners worry that installing solar panels will void their existing roof warranty.

Fact: Most roofing manufacturers allow solar panel installations without voiding warranties, provided the work is done by certified professionals and appropriate installation guidelines are followed.

At GenSun Roofing, we ensure all installations comply with manufacturer requirements and local building codes, preserving your roof warranty and your investment.

Myth 6: Solar Panels Are Too Heavy for My Roof

Weight concerns are common, especially for older roofs or homes with structural questions.

Fact: Solar panels are relatively lightweight, usually adding about 3-5 pounds per square foot. Most residential roofs can support this additional weight without issue.

Before installation, we conduct structural assessments to confirm your roof’s ability to support solar panels safely. If any reinforcements are needed, we recommend solutions to ensure safety and longevity.

Myth 7: Solar Panels Require Constant Maintenance and Damage My Roof

Some homeowners believe solar panels need frequent maintenance and could lead to roof damage over time.

Fact: Solar panels are designed to be low maintenance, typically requiring only occasional cleaning to maintain efficiency. Properly installed panels do not cause damage and can even shield your roof from some environmental elements.

GenSun Roofing provides maintenance guidance and support to keep both your roof and solar panels in excellent condition.

Myth 8: Solar Panels Don’t Perform Well in New Jersey’s Climate

New Jersey’s cloudy days and winter snow sometimes cause doubt about solar panel effectiveness.

Fact: Solar panels generate electricity even on cloudy days, though output is naturally higher with direct sunlight. Modern panels perform efficiently in diverse weather conditions, including cold and snowy climates.

Snow typically slides off angled panels, and solar energy can be generated during winter months. Combining a new, energy-efficient roof with solar panels maximizes your home’s energy performance year-round.

Myth 9: Solar Panels Are Too Expensive to Be Worth It

The upfront cost of solar installation often intimidates homeowners.

Fact: While the initial investment can be significant, solar panels offer long-term savings on energy bills and increased home value. New Jersey offers various incentives, rebates, and financing options to make solar affordable.

At GenSun Roofing, we provide no upfront cost options and flexible financing to help NJ homeowners access solar benefits without breaking the bank.

Myth 10: Solar Panels Will Make My Home Look Ugly

Some homeowners worry that solar panels will ruin their home’s appearance.

Fact: Solar panel designs have improved dramatically, offering sleek, low-profile options that blend well with various roof styles. Some homeowners view solar as a status symbol of sustainability and innovation.

GenSun Roofing helps select and install solar systems that complement your home’s aesthetic while maximizing energy production.
