Roof Decking (Sheathing)
The roof decking, also called sheathing, is the material that forms the base layer of the roof. It is typically made from plywood or oriented strand board (OSB). The decking supports all other roofing components, including the shingles, and helps distribute weight across the structure.
Important Facts:
- Roof decking is usually made from ½-inch to ¾-inch thick material.
- It is designed to withstand various weather conditions, but over time, it can degrade due to moisture or age.
Roof Trusses and Rafters
Roof trusses and rafters are structural components that provide the framework for your roof. These parts are responsible for supporting the decking and the rest of the roofing system. Trusses are prefabricated, triangular frameworks that are commonly used in modern homes, while rafters are traditional, sloped beams that form the roof's pitch.
What You Should Know:
- Trusses are more cost-effective and quicker to install compared to rafters.
- Rafters offer more flexibility for custom roofing designs but may require more labor.
Roof Underlayment
The underlayment is a protective barrier that sits between the decking and the roof covering (such as shingles or tiles). It helps to prevent water from penetrating the roof and damaging the structure below. Underlayment is typically made of felt, synthetic materials, or rubberized asphalt.
Benefits:
- It provides an extra layer of protection against leaks.
- Modern underlayment is more durable and resistant to extreme temperatures.
Roofing Shingles or Tiles
Shingles or tiles are the outermost layer of your roof and provide the first line of defense against the elements. These materials are available in various styles, including concrete roof tile, asphalt shingles, wood shakes, clay tiles, and metal panels. Asphalt shingles are the most common due to their affordability and durability.
Shingles/Tile Facts:
- Asphalt shingles can last between 15 to 30 years, depending on the quality and climate conditions.
- Metal roofing is growing in popularity due to its longevity and energy efficiency.
- Concrete roof tiles can last 20-25 years after which the underlayment should be replaced. You can reuse the existing tile and this is called a raise and re-set.
Flashing
Flashing is a thin metal material used to prevent water from entering vulnerable areas, such as joints and seams. It’s typically installed around chimneys, vents, skylights, and roof valleys. Without proper flashing, water can seep into your home and cause significant damage.
Key Areas to Check for Flashing:
- Chimneys
- Skylights
- Roof Valleys
- Vent pipes
Roof Vents
Proper ventilation is essential for maintaining the health of your roof and attic. Roof vents help regulate the temperature in your attic by allowing hot air and moisture to escape. This helps prevent ice dams, mold growth, and excessive heat buildup that can damage the roofing materials.
Types of Roof Vents:
- Ridge Vents: Installed at the peak of the roof for continuous airflow.
- Soffit Vents: Located under the eaves, allowing air to enter the attic.
- Gable Vents: Installed on the side walls of the home to improve ventilation.
- O’Hagin Vents: Installed at the lower sections of the roof for air intake and the upper sections for exhaust.
Gutters and Downspouts
Gutters and downspouts are part of the roof drainage system, designed to carry rainwater away from your roof and foundation. Keeping these components clean and in good condition is essential to prevent water from pooling around your home, which can lead to mold, foundation issues, and even roof damage.
Maintenance Tips:
- Clean gutters regularly to prevent clogs.
- Inspect downspouts to ensure water flows freely away from the foundation.
Did You Know?
- About 1 in 10 homeowners report issues with their roof within the first 5 years after installation.
- A professionally installed roof can last 25 years or more, depending on the materials and maintenance.
