5 Roof Types You Never Knew Existed

Your roof is a complex structure designed to protect your home from the elements. It’s not just a flat surface; it consists of several layers and components that play specific roles in keeping your home safe and comfortable.

Roof Deck

The roof deck is the foundation of your roof. It’s typically made of plywood or oriented strand board (OSB) and serves as the base for all other roofing components.


Underlayment is a water-resistant or waterproof barrier installed on top of the roof deck. It provides an extra layer of protection against moisture infiltration and is crucial for preventing leaks.

Roofing Material

The choice of roofing material is a significant decision. Common options include asphalt shingles, metal, tile, wood, and slate. Each material has its unique characteristics and lifespan.


Flashing is a thin, weather-resistant material installed around roof penetrations like chimneys, vents, and skylights. It prevents water from seeping into vulnerable areas.


Proper ventilation is essential for a healthy roof and home. It allows air to flow through the attic, preventing heat and moisture buildup that can damage your roof and interior.

Eaves and Fascia

Eaves are the edges of your roof that overhang the walls. Fascia is the board that runs along the eaves. Both provide protection and add aesthetic appeal to your home.

Ridge and Hip

The ridge is the highest point of your roof where two slopes meet. Hips are the external angles formed when two roof surfaces intersect. Proper ridge and hip installation are vital for stability and weatherproofing.

Gutters and Downspouts

Gutters collect rainwater and direct it away from your home’s foundation. Downspouts ensure the water flows safely away from the building, preventing water damage.


Understanding the anatomy and components of your roof is essential for homeowners and anyone interested in the world of roofing. A well-maintained roof can extend the lifespan of your home and provide you with peace of mind.
