The roof on your home is more than shingles and nails. A roofing system is complex and has been designed to protect every angle of your home from the elements. As a homeowner, understanding the composition of your roof and the various components is essential—not just for maintenance. If you know the parts, you can better discuss issues or needs with a roofing company in New Jersey when you need their assistance. It’s time for Roofing 101.
Key Takeaways
- There are many parts of the roof, including the roof decking, underlayment, roofing material, flashing, ridge and hip caps.
- Gutters and downspouts are another key piece of the roofing system, as they direct rainwater away from the roof and foundation.
- Proper airflow through ventilation components maintains attic temperature and prevents moisture buildup.
Roof Decking
Often referred to as sheathing, roof decking is the foundational layer of the roof structure upon which all other roofing materials are installed. It provides a flat and stable surface for the attachment of shingles, tiles, or other roofing materials. Typically made of plywood or oriented strand board (OSB), roof decking is installed over the roof trusses or rafters, forming a solid base that supports the weight of the roof and distributes loads evenly across the structure.
Underlayment
Underlayment is a critical component of the roofing system, providing an additional layer of protection between the roof decking and the roofing material. It serves as a waterproof barrier, safeguarding the roof structure and interior of the building from moisture infiltration. Underlayment is typically installed directly on top of the roof decking and beneath the outermost layer of roofing material. Common types of underlayment include asphalt-saturated felt, synthetic underlayment, and rubberized asphalt membranes, each offering varying degrees of durability and weather resistance.
Roofing Material
Roofing material refers to the outermost layer of the roof, the one that you see when looking at your home in New Jersey. There are various types of roofing materials available, including asphalt shingles, metal roofing, wood shakes, clay tiles, and slate. The choice of roofing material depends on factors such as climate, architectural style, budget, and personal preference.
For example, asphalt shingles are the most common roofing material in the United States due to their affordability, ease of installation, and wide range of styles and colors. Metal roofing is known for its durability, longevity, and energy efficiency, making it a popular choice for commercial and residential applications. Wood shakes, clay tiles, and slate offer a timeless and elegant look, but they tend to be more expensive and require specialized installation.
Flashing
Flashing is a crucial component of the roofing system that helps prevent water infiltration at vulnerable areas such as roof penetrations, valleys, chimneys, skylights, and vents. Made of metal, plastic, or rubber, flashing is installed around these areas to create a watertight seal and direct water away from the roof surface. Although often overlooked during inspection, flashing is essential for protecting the roof structure and for preventing water damage.
Gutters and Downspouts
Your roof does not end at the shingles. The gutters and downspouts are essential to the roof system. Gutters are installed along the eaves of the roof to capture rainwater and direct it towards downspouts, which then carry the water down to the ground or a drainage system. Properly functioning gutters and downspouts prevent water from pooling on the roof, which can lead to exterior and foundation damage. Gutters and downspouts are available in various materials, including aluminum, copper, vinyl, and steel, each offering different levels of durability and aesthetic appeal.
Ridge and Hip Caps
Ridge and hip caps are protective coverings installed along the ridges and hips of the roof, where two roof planes meet. They serve both functional and aesthetic purposes, providing a finished appearance and sealing vulnerable areas to prevent water infiltration. Ridge and hip caps are typically made of the same material as the roofing shingles and are designed to blend seamlessly with the rest of the roof.
Ventilation
Yes, your roof needs ventilation in order to function properly. Common ventilation components include ridge vents, soffit vents, gable vents, and attic fans, which promote air circulation and help remove excess heat and moisture from the attic. Additionally, ventilation is needed to make your home more energy efficient, as it helps keep your home cool in the summer and warm in the winter.
