What is Included in a Roof Replacement: An In-Depth Look at the Process

Apr 4, 2023

Roof replacements are a necessary part of maintaining the longevity and structural integrity of your home. As a San Antonio-based roofing company, Cloud Roofing understands the importance of ensuring your roof is in the best possible condition. In this blog post, we'll discuss the various components of a roof replacement, all of which are included in a Cloud Roofing roof replacement. By understanding these key elements, you'll be better prepared and know what to expect during the San Antonio roof replacement process.


Decking, also known as sheathing, is the foundation upon which your roofing system is built. It provides a solid surface for attaching shingles and other roofing materials. During a roof replacement, your contractor will inspect the existing decking for signs of rot, moisture damage, or structural issues. If any issues are found, the damaged decking will be replaced to ensure a strong and sturdy foundation for your new roof.


Flashing is the material used to seal and protect joints, edges, and other vulnerable areas of your roof from water infiltration. Flashing is typically made from metal, such as aluminum or galvanized steel, and is installed around chimneys, skylights, valleys, and roof-to-wall transitions. Your contractor will inspect the existing flashing for signs of rust, corrosion, or damage. If necessary, they will install new flashing to prevent leaks and protect your home from water damage.


Underlayment is a water-resistant barrier installed directly on top of the decking to provide additional protection from moisture, wind, and other elements. There are different types of underlayment, such as felt paper or synthetic options, each with its own advantages. During the roof replacement process, your contractor will remove the old underlayment and install a new one to ensure your roof has a robust layer of protection.

Drip Edge

A drip edge is a metal flashing installed along the eaves and rake edges of your roof to protect the underlying materials from water damage. It directs water away from the fascia and into the gutters, preventing rot and damage to the wood components of your roof. New drip edges will be installed to ensure proper water drainage and protection for your roof and home.

Ice and Water Shields

An ice and water shield is a crucial component of a roofing system. This self-adhering membrane is applied to the eaves, valleys, and other vulnerable areas of the roof to provide an extra layer of protection against water infiltration caused by ice dams or wind-driven rain. Although San Antonio is not known for heavy snowfall, an ice and water shield can still provide valuable protection during heavy rainstorms. During a roof replacement, your contractor will install this shield as needed to ensure your home is protected from the elements.


Shingles are the most visible component of your roofing system and provide the primary layer of protection against the elements. There are various types of shingles, such as asphalt, wood, metal, or tile, each with its own advantages and aesthetic appeal. Removing the old shingles and installing new ones provides your home with a fresh, durable, and weather-resistant covering.


Capping, also known as ridge capping or hip capping, is the process of installing shingles or other roofing materials along the ridge or hip lines of your roof. This helps to seal the joints where different roof planes meet, preventing water intrusion and providing additional protection against wind uplift. During a roof replacement, your contractor will install new capping materials to ensure that these vulnerable areas are properly sealed and protected.

Roof Vents

Proper ventilation is essential for maintaining a healthy and energy-efficient roofing system. Roof vents help regulate temperature and moisture levels in your attic, preventing issues such as mold growth, ice dams, and premature aging of roofing materials. There are various types of roof vents, including ridge vents, soffit vents, and gable vents, each with its own specific function. Expect your contractor to inspect your existing ventilation system and, if necessary, install new roof vents to ensure optimal airflow and energy efficiency.

Pipe Boots

Pipe boots are specially designed flashing used to seal and protect roof penetrations, such as plumbing vent pipes, from water infiltration. They are typically made from a combination of metal and flexible material, allowing them to conform to the shape of the pipe while providing a watertight seal. Inspection of the existing pipe boots for signs of wear or damage and replacing them as needed can help maintain the integrity of your roofing system.
