From the ground, your roof might seem simple—just some shingles, a few vents, and maybe some gutters. But there’s a lot more happening up there than meets the eye! A complete roofing system is made up of several materials, each playing a crucial role in keeping your home safe from leaks, water damage, and harsh weather.
If you’re planning a roof replacement, you might be surprised by the cost—especially if you thought it was just about replacing shingles. But don’t worry! Understanding what goes into a complete roofing system can help you make informed decisions and avoid sticker shock. Let’s explore all the materials that make up a durable, long-lasting roof.
In this blog, we’re going to be covering:
- Materials You Need for a Roof Replacement
Materials You Need for a Roof Replacement
To keep things simple, we’ll break this into three main categories:
- The Shingles
- The Backup Layers
- Extra Protection Materials
1. Roof Decking: The Base Layer
Before we even get to shingles, let’s talk about the foundation of your roof: roof decking .
Decking is made from boards like plywood or OSB (oriented strand board) and acts as the structural base. It connects directly to your home’s frame and provides a solid surface for the other roofing materials to sit on. Without it, your roof wouldn’t have the strength or stability to withstand heavy loads like rain, snow, or even foot traffic during maintenance.
Why is decking important?
Over time, leaks can cause water to seep through the roof and damage the decking. When wood gets waterlogged, it can rot and weaken, making it unsafe and less effective. During a roof replacement, your contractor will inspect the decking and replace any damaged sections.
If your roof is older, the entire decking might need to be replaced to meet modern building codes. However, this is rare unless your roof has suffered from years of neglect or widespread water damage.
2. The Shingle Layer
Next up is the part of the roof you’re most familiar with: the shingles!
Asphalt Shingles
Asphalt shingles are the most common roofing material in North America. They’re durable, affordable, and come in a variety of colors and styles to match your home’s aesthetic.
Each shingle consists of a fiberglass mat covered with asphalt and protective granules. These granules provide color, UV protection, and resistance to wear. Asphalt shingles come in three main types:
– 3-Tab Shingles: Simple, flat, and budget-friendly.
– Architectural Shingles: Thicker and more durable, with a textured, dimensional look.
– Luxury Shingles: The most durable and stylish, often mimicking high-end materials like slate or wood.
These options give homeowners flexibility in terms of cost, appearance, and protection.
Starter Shingles
Before the main shingles go on, starter shingles are installed along the edges of the roof. These strips have adhesive that helps secure the first row of shingles, keeping them from being lifted by wind. Without starter shingles, the bottom edge of your roof would be vulnerable to wind and water damage.
Ridge Cap Shingles
At the very top of your roof, where two slopes meet, you’ll find the ridge cap shingles . These specially designed shingles cover the roof’s peak, providing protection and giving the roof a clean, finished look. Ridge cap shingles are thicker and more durable than regular shingles to handle the extra wear they endure.
3. Reinforcements: The Backup Layers
Beneath the shingles are critical layers that act as your roof’s safety net. These materials provide extra protection against water intrusion.
Underlayment
UnderlaymentThink of underlayment as your roof’s last line of defense. This water-resistant material is rolled out over the decking before shingles are installed. Its job is to protect the decking from water that might sneak past the shingles during heavy rain or high winds.
Underlayment is typically made from either asphalt-saturated felt or synthetic materials. Synthetic underlayment is more common today because it’s lighter, stronger, and more resistant to tearing.
Ice & Water Shield
Ice and water shield is a heavy-duty underlayment made with rubberized asphalt. It’s self-adhesive, creating a watertight seal without the need for nails.
This material is especially important in areas prone to ice dams or heavy rain. It’s typically installed in roof valleys, along eaves, and around vulnerable areas like chimneys and skylights.
Flashing
FlashingFlashing is thin metal, usually aluminum or galvanized steel, that seals gaps and redirects water away from vulnerable areas. You’ll find flashing around chimneys, vents, skylights, and where the roof meets walls.
During a roof replacement, old flashing is usually replaced to ensure everything is watertight and up to current standards.
4. Extra Protection: The Finishing Touches
Finally, let’s talk about the additional components that keep your roof functioning smoothly.
Pipe Boots
Pipe boots are made of rubber or metal and fit around the base of vent pipes that stick out of your roof. These boots create a watertight seal, preventing leaks where the pipes penetrate the decking.
Drip Edge
Drip EdgeDrip edge is metal flashing installed along the edges of your roof. It directs water into your gutters and prevents it from seeping under the shingles, which could cause rot and damage to the fascia board.
Without drip edge, your roof’s edges would be constantly exposed to moisture, leading to premature wear and tear.
Ventilation System
A well-ventilated attic is crucial for a healthy roof. Roof vents , like ridge vents, box vents, or turbine vents, allow hot air and moisture to escape from your attic. Proper ventilation prevents problems like mold, rot, and shingle deterioration.
Gutters
GuttersThough not technically part of the roof, gutters play a vital role in protecting your home. They collect rainwater and direct it away from your foundation. Clogged or damaged gutters can cause water to back up onto your roof, leading to leaks and other issues.
Keeping your gutters clean and in good condition is essential for maintaining your roof’s health.
