Roof Mounted Solar Panel Installation
Roof mounted solar panels are the most popular and cost-effective choice for homeowners. This solution uses the existing, sun-exposed space on your roof to generate clean energy, reduce your utility bills, and move you toward energy independence.
As a trusted partner in your solar journey, SunnyMac specializes in safe, secure, and aesthetically clean roof solar installations. Our process is built on integrity and stability, ensuring your home and your investment are protected from day one.
Why Put Solar Panels on Your Roof?
Choosing a roof mounted system is the most common path to home solar for several key reasons:
- Maximum Space Efficiency: It utilizes your roof, an otherwise unused structural asset, leaving your yard and property completely open.
- Cost-Effective Installation: Mounting on an existing roof is typically more straightforward and requires less structural material than ground-mounted systems, often leading to lower installation costs.
- Clean Aesthetics: Modern racking systems and our professional installation process ensure the panels look great and are seamlessly integrated with your home’s design.
Our residential solar energy systems have helped thousands of households harness the power of the sun to reduce their energy costs and environmental footprint. See our solar installations in action here.
Your Roof’s Health is Our First Priority
The number one concern for homeowners is, “Will solar panels damage my roof?”
With SunnyMac, the answer is no. We are not just a solar installer; we are an Owens Corning (OC) Platinum Preferred Roofing Partner. This is a certification only the top 1% of roofers in the country receive.
We Are Certified Roof Experts
We were awarded the OC Platinum Preferred Roofing Partner Excellence Awards for Service, Product, and Warranty in 2025.
We Assess First
Our team performs a thorough roof integrity assessment before any installation. If your roof needs repairs, we can manage the process to ensure your solar investment is built on a solid foundation.
We Guarantee Our Work
We use industry-best mounting and flashing techniques to ensure your roof remains watertight and structurally sound for decades to come.
Our Roof Mounting Process: Designed for Safety & Security
While our home solar installation process gives you a full overview, the physical roof installation involves specific, careful steps to protect your home.
- Roof Integrity & Rafter Assessment
Our NABCEP-certified team confirms your roof’s health and precisely locates the structural rafters to ensure a secure, safe foundation for the system. - Installing Secure Mounts & Flashing
We attach waterproof flashing and mounts directly into the rafters. This three-layer sealing process is critical for preventing leaks and is a step we take with extreme care. - Assembling the Racking System
Lightweight, durable aluminum rails (the racking) are attached to the mounts. This frame is what the solar panels will be secured to, allowing for airflow underneath the panels. - Securing and Wiring the Panels
We mount the solar panels to the racking and complete the system wiring. Our team ensures a clean, uncluttered installation with no messy wires.
Roof Mounted vs. Ground Mounted Solar
How does a roof system stack up against a ground-mounted one? Here’s a quick comparison to help you see the difference.
| Feature | Roof Mounted Solar Panels | Ground Mounted Solar Panels |
| Space used | Uses existing roof space. No yard space is lost. | Requires open land in your yard. |
| Cost | Generally lower upfront cost. | Higher upfront costs (requires trenching & foundation). |
| Efficiency | Good, but dependent on your roof’s angle and direction. | Excellent. Can be angled perfectly for max sun exposure. |
| Best For | Most homes in PA, NJ, MD, DE. | Properties with large, open land or shaded roofs. |

Frequently Asked Questions
What happens if my roof is old?
We typically recommend that a roof has at least 10-15 years of life left before installing solar. As an OC Platinum Preferred roofer, we will give you an honest, expert assessment and can help you with a roof replacement if needed.
Do you install on all roof types?
Yes. Our experienced teams are trained to install on all common roof types in our area, including asphalt shingle, metal, and flat roofs. Each has a specific, approved mounting method.
What if my roof is shaded by trees?
During your free consultation, we conduct a solar analysis. If your roof has too much shade, we will be transparent about it. We may recommend tree trimming (if possible) or discuss a ground-mounted system as a more efficient alternative.
Will the solar panels cause my roof to leak?
This is a primary concern for homeowners, and it’s why our expertise as an Owens Corning (OC) Platinum Preferred Roofing Partner is so important. The answer is no. We use a professional, multi-layer waterproofing and flashing system for every roof penetration, which is a process we have been awarded for. This ensures your roof remains 100% watertight, and we stand by our workmanship with integrity.
Are the solar panels too heavy for my roof?
Solar panel systems are surprisingly lightweight (typically only 3-4 pounds per square foot) and are designed to be safely distributed across your roof’s structure. As part of our careful and ethical process, our engineering team performs a full structural assessment to confirm your roof’s load-bearing capacity. We only move forward with an installation if it is 100% structurally sound.
What happens when I eventually need to replace my roof in the future?
This is a great, long-term question that highlights our stability as a partner. As a full-service solar and roofing company, SunnyMac can handle the entire process. We will professionally remove the panels, store them safely, replace your roof as an OC Platinum Preferred installer, and then reinstall your solar system. It’s an end-to-end service that non-roofing solar companies can’t offer.
