Underlayment
The underlayment is a water-resistant barrier that is installed on top of the roof deck to protect the roof from water damage. It is typically made of felt paper or synthetic materials.
Asphalt Shingles
Flashing
Ridge Vent
The ridge vent is a ventilation system installed at the peak of the roof to allow hot air and moisture to escape from the attic, helping to regulate temperature and prevent moisture buildup.
Gutters & Downspouts
Fascia & Soffit
Truss
A truss is a structural framework designed to support the roof of a building. It consists of triangular units that are connected together to form a strong and stable roof structure.
Roof Ridge
Overhang
This is the part of a roof that extends beyond the exterior walls of a building. Overhangs provide protection from the elements and help to keep water away from the walls.
Gable
Eave
Hip
A hip is the external angle formed by the intersection of two sloping roof surfaces. It is a common feature in hip roof designs and helps to distribute the weight of the roof evenly.
Skylight
A skylight is a window installed in the roof of a building to allow natural light to enter the interior space. Skylights can help to brighten up a room and provide increased ventilation.
Dormers
Rake Edge
Roof Valley
A roof valley is a V-shaped channel named for where two sloping roof planes meet. Its main function is to direct rainwater and snowmelt towards the gutters or downspouts, preventing water from pooling on the roof and causing leaks or damage.
Being familiar with what each asphalt roof part is called and its function is crucial in maintaining the structural integrity and longevity of your home. From the roof deck to the roof valley, each component plays a vital role in protecting your home from water damage, improving energy efficiency, and enhancing the overall curb appeal.

Parts of a Metal Roof
Metal roofs have several parts that are different from asphalt shingle roofs. Some of the key differences include:
Material: Metal roofs are typically made of steel, aluminum, copper, or zinc, while asphalt shingle roofs are made of asphalt and fiberglass or organic materials.
Panels: Metal roofs are made up of large panels that are installed in overlapping rows, while asphalt shingle roofs are made up of individual shingles that are installed in rows.
Fasteners: Metal roofs are typically fastened with screws or clips, while asphalt shingle roofs are fastened with nails.
Flashing: Metal roofs require flashing to prevent water from seeping into the seams between panels, while asphalt shingle roofs require flashing to prevent water from seeping into the joints between shingles.
Underlayment: Metal roofs typically require a synthetic underlayment to provide additional protection against water infiltration, while asphalt shingle roofs may use felt paper or synthetic underlayment.
Ventilation: Metal roofs may require additional ventilation to prevent condensation and moisture buildup, while asphalt shingle roofs may have built-in ventilation systems.
Overall, metal roofs have a different construction and installation process compared to asphalt shingle roofs, and they offer different benefits such as durability, longevity, and energy efficiency.

Parts of a Flat Roof
Flat roofs have many key differences compared to asphalt shingle roofs or metal roofs. Some of the main differences include:
Roofing Material: Flat roofs typically use different materials than sloped roofs. Common materials for flat roofs include built-up roofing (BUR), modified bitumen, EPDM rubber, PVC, TPO, and spray foam. These materials are specifically designed to provide a waterproof barrier on a flat surface, whereas asphalt shingles and metal roofing are better suited for sloped roofs.
Roof Structure: Flat roofs require a different structural design compared to sloped roofs. Flat roofs need to be built with a slight slope to allow for proper drainage of water. This slope is typically achieved through the use of tapered insulation or crickets. In contrast, sloped roofs naturally shed water, so they do not require the same level of slope.
Flashing and Seams: Flat roofs often have more seams and flashing details compared to sloped roofs. This is because flat roofs are more prone to water pooling and leaks, so extra care must be taken to ensure that all seams and flashing are properly sealed and maintained. In contrast, sloped roofs have fewer seams and flashing details, which can make them easier to install and maintain.
Overall, flat roofs have unique characteristics and requirements that set them apart from asphalt shingle roofs and metal roofs. It is important to consider these differences when choosing a roofing system for your building to ensure that you select the best option for your specific needs.

FAQs
- Can you replace just part of a roof?
Yes, it is possible to replace just part of a roof. This is known as a partial roof replacement. In some cases, only a section of the roof may be damaged or in need of repair, so replacing just that portion can be a cost-effective solution.
When replacing part of a roof, it is important to ensure that the new materials match the existing roof in terms of color, style, and quality. This will help maintain the overall aesthetic of the roof and prevent any issues with water leakage or structural integrity.
It is recommended to consult with a professional roofing contractor to assess the extent of the damage and determine the best course of action for replacing part of a roof. They will be able to provide guidance on the most appropriate materials and techniques to use for the partial replacement.
- Can you reshingle just part of a roof?
Yes, it is possible to reshingle just part of a roof. This is often done when only a section of the roof is damaged or in need of repair. The process involves removing the old shingles from the damaged area, inspecting the underlying roof deck for any issues, and then installing new shingles in the affected area.
It’s important to match the new shingles with the existing ones to ensure a cohesive look. We also recommend hiring a professional roofing contractor to ensure the job is done safely and correctly and to prevent any further damage to the roof.
- What’s the highest part of a roof?
The highest part of a roof is typically the peak or ridge. This is where the two sloping sides of the roof meet at the top, forming a point or line that runs along the length of the roof.
The peak or ridge is often the most visually prominent part of a roof and can be accentuated with decorative elements such as finials or weather vanes. It is also an important structural element, as it helps to distribute the weight of the roof evenly and provides stability and support.
- Is a skylight considered a part of the roof?
Yes, a skylight is considered a part of the roof. A skylight is a window installed in the roof of a building to allow natural light to enter the space below. It’s typically integrated into the roof structure and is designed to be waterproof.
Skylights are often installed during the construction of a roof and are considered an integral part of the overall roofing system. They provide additional natural light and ventilation to the interior space while also adding aesthetic appeal to the roofline. Proper installation and maintenance of skylights are important to ensure they function effectively and do not compromise the integrity of the roof.
Roof Components: Know Your Structure
Understanding roof terminology, whether it be an asphalt roof, metal roof, or flat roof, is crucial for residential and business property owners alike. Each component plays a vital role in protecting the structure from the elements and ensuring the longevity of the roof.
