1. Roof Deck

The roof decking is the foundation of your roof, providing structural support for the entire system. It’s typically made of plywood or oriented strand board (OSB) and is attached to the rafters or trusses.

Why you should care about this: A sturdy roof deck is essential for the integrity and longevity of your roof structure. If it becomes damaged or weakened, it can lead to sagging and leaks.

2. Underlayment

Underlayment is a layer of material installed over the roof deck and beneath the outer roofing material (shingles, tiles, or metal panels). It serves as an additional barrier against moisture penetration.

Why you should care about this: Underlayment plays a crucial role in preventing water from seeping into your home’s interior. It acts as a backup waterproofing layer.

3. Shingles or Roofing Material

Shingles are the visible, outermost layer of your roof. They come in various materials, including asphalt, wood, metal, and slate, among others. Shingles provide protection from weather elements.

Why you should care about this: Shingles not only protect your home but also contribute to its aesthetic appeal. The choice of roofing material can affect your home’s energy efficiency and curb appeal.

4. Flashing

Flashing is a thin, weather-resistant material (usually metal) used to seal joints and seams on your roof. It’s placed around roof penetrations like chimneys, vents, skylights, and in valleys.

Why you should care about this: Properly installed flashing prevents water from seeping into vulnerable areas, reducing the risk of leaks.

5. Roof Vents & Ventilation

Roof vents allow air circulation in your attic or roof space. They come in various styles, including ridge vents, soffit vents, and gable vents. Adequate ventilation helps regulate temperature and moisture levels.

Why you should care about this: Proper ventilation prevents moisture buildup, reduces energy costs, and extends the lifespan of your roof.

6. Gutters & Downspouts

Gutters are channels attached to the edges of your roof that collect rainwater and guide it away from your home. Downspouts direct water from the gutters to the ground.

Why you should care about this: Gutters prevent water from pooling on your roof and protect your foundation from water damage. Proper drainage is essential for home maintenance.

7. Roof Ridge & Eaves 

The roof ridge is the highest point where two roof slopes meet, forming a horizontal line along the top of the roof. Eaves are the edges that overhang beyond the walls.

Why you should care about this: The ridge vent allows hot air to escape from the attic, while the eaves help protect your home’s walls from water and provide shade.

8. Chimney & Flashing

If your home has a chimney, it protrudes through the roof and requires proper flashing to prevent water penetration. Flashing around the chimney is essential to keep your roof watertight.

Why you should care about this:Correctly installed flashing ensures that water does not infiltrate the roof and cause damage to the chimney or interior spaces.

9. Skylights & Roof Penetrations

Skylights and other roof penetrations, such as vents and pipes, are areas where the roof’s integrity can be compromised. Proper sealing and flashing are essential for watertightness.

Why you should care about this: Skylights provide natural light, but they must be well-maintained and sealed to prevent leaks. Roof penetrations can be vulnerable points for water infiltration.
