When it comes to protecting your home, your roof plays one of the most important roles. But have you ever wondered what is a roofing system and how it actually works? At State Restoration Services, we believe that understanding your roof helps you make better decisions about maintenance, repairs, and upgrades.
In this article, we’ll break down what a roofing system is, what components it includes, the different types available, and how to care for yours. Let’s get started.
What Is a Roofing System?
Simply put, a roofing system is more than just shingles or tiles on top of your house. It’s a complete structure made up of several layers and materials designed to protect your home from the elements — rain, wind, snow, and heat.
A roofing system works together as one unit to keep your home dry, insulated, and energy-efficient. It includes the roof covering, underlayment, decking, flashing, ventilation, and gutters — all working in harmony.
Here’s a quick look at the main parts that make up a roofing system.
Key Components of a Roofing System
1. Roof Decking
The decking (or sheathing) is the foundation layer that supports all other roofing materials. Usually made of plywood or OSB (oriented strand board), it’s attached directly to the roof’s frame.
2. Underlayment
Placed between the decking and the outer roofing material, the underlayment acts as a waterproof barrier. It prevents moisture from seeping through in case of a leak in the shingles or tiles.
3. Roof Covering
This is the visible outer layer of your roofing system. Common options include:
-
Asphalt shingles
-
Metal roofing
-
Clay or concrete tiles
-
Slate
-
Wood shakes
The choice depends on your climate, home style, and budget.
4. Flashing
Flashing is made from metal (usually aluminum or steel) and is used to seal roof joints and edges. You’ll find it around chimneys, skylights, and vents to keep water from sneaking in.
5. Ventilation System
Proper airflow prevents heat and moisture buildup in your attic. Roof vents, ridge vents, and soffit vents work together to maintain a balanced temperature and prevent mold growth.
6. Gutters and Downspouts
Although technically not part of the roof itself, gutters are crucial for directing water away from your home’s foundation — protecting both the roof and your property.

Schedule regular inspections (twice a year, ideally in spring and fall).

Clean gutters and downspouts to prevent water buildup.
