A full roof replacement is a significant home improvement project that ensures the safety and durability of your home. But what is included in roof replacement? Whether you’re facing storm damage, wear and tear, or just looking to upgrade, understanding the components of this service is crucial. This comprehensive guide will walk you through the nine essential materials and components of a complete roof replacement.
Roof Decking
Roof decking, or roof sheathing, is the wooden foundation on which the rest of your roof is built. There are two primary types: plank decking and sheet decking.
- Plank Decking: Plank decking is ideal for traditional roofs made from elongated wooden boards, typically in 1×6 or 1×8 sizes.
- Sheet Decking: Composed of plywood or OSB (oriented strand board), sheet decking provides a flat, solid base for roofing materials. OSB consists of wood chips or strips compressed into a 7/16” sheet, while plywood varies in thickness from ⅜” to ¾”.
Replacing any rotten or compromised roof decking is essential before installing new roofing materials. This step ensures the structural integrity of your roof.
Drip Edge
A drip edge is metal flashing installed at the edges of your roof to prevent water from getting underneath the roofing materials and underlayment. It protects your fascia board and the edges of your roof decking from water damage.
- Eaves and Rakes: A drip edge is installed along these areas to direct water away from the roof.
- Building Codes: Proper drip edge installation is required by building codes and is necessary for passing inspections.
Including drip edge in your roof replacement estimate is crucial. Omitting it can lead to severe water damage and additional repair costs.
Underlayment
Underlayment is a felt or synthetic material laid directly over the roof decking before the main roofing material is installed. It acts as a secondary barrier against water penetration.
- Felt Underlayment: Available in 15 lb. and 30 lb. rolls, felt underlayment is a traditional option. The 30 lb. version is thicker and more durable.
- Synthetic Underlayment: Made from polyethylene or polypropylene, synthetic underlayment is more moisture-resistant, durable, and better at holding nails.
Despite its higher cost, synthetic underlayment offers superior water protection and longevity.
Ice and Water Shield
Ice and water shield is a waterproof membrane applied to specific roof areas prone to water damage, such as valleys and around penetrations.
- Installation Areas: Commonly installed in roof valleys, around chimneys, and along roof edges in regions prone to ice damming.
- Protection: Provides additional waterproofing to prevent leaks from ice and water infiltration.
In areas with heavy snowfall, building codes often require ice and water shield along roof edges to prevent ice damming.
Roof Flashing
Roof flashing directs water away from critical areas where roofing materials meet vertical surfaces like walls and chimneys.
- Material Choices: Commonly used materials include aluminum, steel, and copper. Steel is preferred for its durability and clean appearance, while copper offers an upscale look.
- Replacement: It’s advisable to replace roof flashing during a roof replacement to ensure uniformity and prevent future leaks.
Properly installed roof flashing is essential to prevent water from seeping into your home at these vulnerable points.
Roofing Material
The roofing material is the top layer of your roof system and comes in various options, each with its unique benefits and costs.
- Asphalt Shingles: Popular for their affordability and variety.
- Standing Seam Metal Roofing: Known for durability and longevity.
- Cedar Shake Roofing: Offers a natural, rustic appearance.
- Synthetic Roofing: Mimics the look of other materials while offering enhanced durability.
- Slate Roofing: Highly durable and aesthetically pleasing, though more expensive.
Choosing the right roofing material impacts the cost, aesthetics, and lifespan of your roof. Ensure you research and select the material that best suits your needs and budget.
Ridge Capping
Ridge capping seals the roof at the top where two slopes meet, providing a finished look and additional protection.
- Material: Made from the same material as the main roofing but pre-bent to fit the roof’s ridge.
- Importance: Proper ridge capping prevents leaks and ensures a secure seal at the roof’s highest point.
Using the appropriate ridge capping material is essential to prevent potential leaks and maintain the roof’s integrity.
Roof Vents
Roof vents are crucial for proper attic ventilation, helping to regulate temperature and moisture levels.
Types of Ventilation Systems:
- Active Ventilation: Includes turbine vents, power vents, and solar-powered vents.
- Passive Ventilation: Includes static vents, ridge vents without baffles, and gable-end vents.
Proper attic ventilation extends the life of your roof and reduces energy costs by allowing hot air to escape and preventing moisture buildup.
Pipe Boots
Pipe boots are specialized flashing components that seal around pipes protruding from your roof, such as plumbing vents.
- Materials: Common materials include synthetic rubber (neoprene), plastic, lead, and copper.
- Durability: Neoprene pipe boots are affordable and durable, though they may need replacement every 10 years due to cracking.
Ensuring all pipe boots are correctly installed and in good condition is critical to preventing leaks around roof penetrations.
A comprehensive roof replacement involves more than just new shingles. It includes several critical materials and components, each vital in protecting your home. By understanding what is included in roof replacement, you can ensure you receive a complete, high-quality roofing system that will stand the test of time.
