Anatomy of a Roof: Breaking Down Every Layer From Shingle to Sheathing | Cicero Secure Roofing

When most homeowners in Cicero look at their roof, they see shingles — but a roof is far more than just what’s on the surface. Every roof is a system of carefully layered components that protect your home from weather, improve energy efficiency, and boost curb appeal.

At Cicero Secure Roofing, we believe that understanding the anatomy of a roof can help you make smarter decisions when it’s time for maintenance, repair, or a full replacement.

Why Understanding the Anatomy of a Roof Matters

Your roof is one of the most important investments you’ll ever make in your home. By learning about each layer — from the visible shingles down to the sheathing — you’ll know what to look for when signs of wear appear and when to call professional roofing experts in Cicero.

That’s why in this guide, we’ll walk you through the anatomy of a roof: breaking down every layer from shingle to sheathing, so you can see how each part works together to protect your home.

Anatomy of a Roof: Breaking Down Every Layer From Shingle to Sheathing

Here’s a closer look at the different layers that make up a well-built roofing system:

1. Shingles – The First Line of Defense

Shingles are the most visible part of your roof. Whether you choose asphalt, wood, or designer options, shingles protect against rain, wind, and UV rays.

2. Underlayment – Extra Waterproofing

Beneath the shingles lies the underlayment, a water-resistant barrier that adds protection against leaks during storms — crucial for Illinois weather.

3. Flashing – Sealing the Weak Points

Flashing is installed around chimneys, vents, and valleys to keep water from sneaking in at vulnerable spots. Without it, leaks are almost guaranteed.

4. Roof Decking (Sheathing) – The Foundation Layer

The sheathing is usually made from plywood or OSB and serves as the strong foundation that holds everything together. This is where Cicero Secure Roofing ensures structural integrity during every roof replacement.

5. Ventilation Systems – Letting Your Roof Breathe

Proper ventilation prevents heat and moisture buildup, which can extend the lifespan of your roof and lower energy bills.

6. Insulation – Energy Efficiency Booster

Quality insulation below the roof deck improves indoor comfort and keeps your heating and cooling costs under control.
