Roof Replacement
Understanding Your Roof System
While the shingles are all you see, your roof is actually a system with many parts that work together to keep your house dry and comfortable. The focus is not just on keeping the weather out but also on letting in fresh air to prevent a buildup of heat and humidity in the attic. Here are the basic parts involved in a shingle roof replacement, starting with the innermost layer.
- Roof deck: The deck is the foundation of your roof, usually made of plywood or oriented strand board (OSB). If you choose a full tear-off replacement, the contractor will strip your roof down to this layer.
- Ice and water shield: This is a self-adhesive membrane applied along the roof’s perimeter from the eaves up. It should reach 3 feet beyond the inside of the wall and cover any valleys to prevent ice dams and wind-driven rain from reaching the decking.
- Underlayment: Underlayment is a water-resistant barrier installed over the roof deck. This synthetic layer covers the entire roof deck and is the second line of defense against leaks, after the shingles.
How Long Should Your Roof Last?
The lifespan of a roof varies depending on the material used, the quality of installation, climate conditions, and ongoing maintenance. However, here’s a general estimate for common roofing materials.
| Roofing Material | Expected Lifespan |
| Architectural asphalt shingles | 30 years |
| Three-tab asphalt shingles | 20 years |
| Clay or concrete tiles | 100+ years |
| Metal roofing | 40–80 years |
| Wood shakes | 40–50 years |
| Slate | 60–150 years |
One way to gauge your roof’s potential lifespan is to look at the manufacturer’s warranty. Most asphalt shingle manufacturers offer warranties ranging from 20–30 years, while some premium options boast 50-year or even “lifetime” warranties. Keep in mind that these are typically limited warranties, meaning they may only cover certain defects or have prorated coverage over time.
Choosing the Right Roofing Material
The roofing material you choose significantly impacts your home’s appearance, energy efficiency, durability, and overall cost. Here’s a brief look at some of the most popular options:
- Asphalt shingles: The most common choice in America, known for affordability and versatility.
- Metal roofing: Increasingly popular for its longevity, energy efficiency, and modern look.
- Wood shakes or shingles: Offer a classic, natural look but require more maintenance.
- Clay or concrete tiles: Extremely durable and fire-resistant, ideal for warmer climates.
- Slate: A high-end, long-lasting option with a unique appearance.
