Roofing & Solar Glossary: Speak the Language Before You Sign

Before you commit to a roofing or solar project, understanding industry jargon is essential. Whether you’re exploring metal roofing and solar panels, planning an upgrade with Gainesville FL metal roofing, or hiring experienced roofers in Gainesville, knowing the language helps you make informed decisions. From “inverter” to “underlayment,” the terminology used in proposals and walkthroughs can be overwhelming. This glossary simplifies complex terms so you can confidently evaluate quotes, ask the right questions, and align your choices with your home’s goals. Roofing and solar aren’t everyday investments—so don’t leave things to guesswork. Use this guide to empower your next conversation and make your experience with contractors more transparent, efficient, and productive.

When it comes to repairing or replacing your roof or exploring solar options, the terms contractors use can sound like a foreign language. Underlayment, soffit, pitch, inverter—what does it all mean? We get it. Roofing and solar projects are big investments, and you should never feel in the dark about what you’re signing up for.

We put together this glossary to help you cut through the jargon and gain confidence as you plan your project. Whether you’re meeting with an estimator, reviewing a proposal, or watching the crew in action, this guide helps you speak the language and ask the right questions.

Roofing Terms

Shingles – The outermost layer of your roof, typically made of asphalt, metal, tile, or slate. Think of these as your roof’s armor against the elements.

Underlayment – A moisture-resistant or waterproof layer placed under the shingles. It adds an extra line of defense in case water sneaks past the outer layer.

Flashing – Thin metal (usually aluminum or steel) installed around roof edges, chimneys, and vents to direct water away from seams or gaps.

Fascia – The horizontal board along the edge of the roof, often where gutters are attached. It helps support the bottom row of shingles and gives the roof a clean finish.

Soffit – Located underneath the roof’s overhang, it helps ventilate the attic and protect the rafters from weather exposure.

Pitch – The steepness or angle of your roof. A higher pitch sheds water more easily, but may also require different materials and installation methods.

Decking – The base layer of the roof (usually plywood) that everything else is built on. If your roof has damage from leaks or rot, this is often the part that needs replacing.

Ventilation – Essential for allowing hot air and moisture to escape from the attic. Proper ventilation extends the life of your roof and keeps your energy bills in check.

Ice & Water Shield – A self-adhering waterproof membrane used in vulnerable areas like valleys and eaves to guard against leaks.

Solar Terms

Photovoltaic (PV) Panels – The solar panels that capture sunlight and convert it into electricity. These are what most people picture when they think “solar.”

Inverter – The device that converts the direct current (DC) electricity generated by your solar panels into alternating current (AC) electricity used in your home.

Net Metering – A billing arrangement that gives you credit for excess electricity your solar system sends back to the grid.

Kilowatt (kW) – A measurement of power. Your solar system’s size is typically measured in kilowatts (e.g., a 6kW system).

Kilowatt-hour (kWh) – A measurement of energy usage. Your electric bill is based on how many kWh your home uses in a month.

Production Estimate – A projection of how much electricity your solar system will generate based on your location, sun exposure, and system size.

Battery Storage – An optional add-on that stores excess solar energy for use when the sun isn’t shining (like at night or during outages).

Interconnection – The process of connecting your solar system to the public utility grid so you can share power and access net metering.

Solar-ready Roof – A roof built or upgraded with solar in mind—typically newer, sturdy, and with proper pitch and orientation.
