Difference Between a Soaker and A Flashing?

Difference Between a Soaker and A Flashing?

A soaker and a flashing are two important elements in roof construction. While they serve similar purposes, they have distinct differences. Let’s explore the disparity between a soaker and a flashing based on the information gathered from various sources.

Key Takeaways:

  • A soaker and a flashing are crucial components in roof construction.
  • A soaker is designed for double-lapped products like plain tiles and slates, while flashings are more versatile and can be used with various types of tiles.
  • Soakers create a watertight seal around roof penetrations, while flashings protect areas where water might penetrate.
  • Soakers extend up the wall, while flashings can cover the tiles or be installed under them.
  • Soakers are typically made of lead, while flashings can be made of various materials.

What is a Soaker?

A soaker is a crucial component used in roof construction, particularly with double-lapped products like plain tiles and slates. Its primary function is to provide support on the tile below, as it is situated between each tile headlap. Soakers play a vital role in preventing water penetration and leaks by creating a watertight seal around roof penetrations such as chimneys and vents.

The length of a soaker typically includes the tile gauge, headlap, and a short turn over the top of the tile. It extends 100mm over the tile and 75mm up the wall, ensuring thorough protection against water ingress. To cover the soaker, a step flashing is used.

“Soakers are an essential part of any roof construction, helping to maintain the integrity of the roof by preventing water damage. By creating a watertight seal around penetrations, soakers play a crucial role in ensuring a reliable and durable roofing system.” – Roofing Expert

Key Features of Soakers:

  • Used with double-lapped products like plain tiles and slates
  • Prevents water penetration and leaks
  • Creates a watertight seal around roof penetrations
  • Extends 100mm over the tile and 75mm up the wall
  • Covered with a step flashing
Soaker Flashing
Application Used with double-lapped products like plain tiles and slates More versatile and can be used with various types of tiles
Function Provides support on the tile below and prevents water penetration and leaks Protects areas where water might penetrate, such as junctions between tiling and vertical walls
Material Typically made of lead Can be made of various materials such as lead or glass reinforced plastic (GRP)

What is a Flashing?

A flashing is a crucial element in roof construction that plays a vital role in protecting areas vulnerable to water penetration. It is commonly used to seal joints and transitions between different roofing materials or where the roofing intersects with other structures such as walls or chimneys. By directing water away from these vulnerable areas, flashings help prevent leaks and potential water damage.

There are various types of flashings depending on the specific application and roofing materials used. One common type is the cover flashing, which extends over the tiles and turns into cut or brickwork joints in the wall. This type of flashing provides a protective barrier and ensures a watertight seal at the junction between the roof and the vertical wall.

Flashing is a crucial element in roof construction that plays a vital role in protecting areas vulnerable to water penetration.

In addition to cover flashings, another type of flashing commonly used is the secret gutter. This type of flashing is often employed with flat single-lapped tiles. It captures and drains away water that runs sideways off the tiles, preventing water from infiltrating the roof and causing potential damage.

The choice of flashing materials can vary based on factors such as the desired level of protection, the type of roof tiles, and the specific application. Common materials used for flashings include lead and glass reinforced plastic (GRP), with lead being a popular choice due to its durability and flexibility.

Table: Comparison between Soaker and Flashing

Criteria Soaker Flashing
Application Double-lapped products like plain tiles and slates Versatile, compatible with various types of tiles
Function Provide support and create a watertight seal around roof penetrations Protect vulnerable areas from water penetration
Material Typically made of lead Can be made of various materials including lead or GRP

As evident from the table, while both soakers and flashings serve crucial roles in roof construction, they differ in terms of their applications, functions, and compatibility with different roofing materials. Soakers are specifically designed for double-lapped products like plain tiles and slates, providing support and creating a watertight seal around roof penetrations. On the other hand, flashings are more versatile and can be used with various types of tiles. They protect vulnerable areas from water penetration and are available in different materials based on the specific requirements of the roof.

In the next section, we will further explore the comparison between soakers and flashings in terms of their construction, installation, and overall effectiveness in preventing water penetration and ensuring the longevity of roofs.

Comparison between Soaker and Flashing

When it comes to roof construction, two key components play a significant role: soakers and flashings. While they share the common purpose of preventing water penetration, they differ in their applications and compatibility with various roofing materials.

Soakers are specifically designed for double-lapped products like plain tiles and slates. They are situated between each tile headlap, providing support on the tile below. Soakers extend 100mm over the tile and 75mm up the wall, creating a watertight seal. Typically made of lead, they ensure a strong and durable barrier against water leaks.

Flashings, on the other hand, offer more versatility and can be used with different types of tiles, including profiled and flat tiles. They come in various forms depending on the specific application. Cover flashings extend over the tiles and turn into cut or brickwork joints in the wall, offering comprehensive protection. Meanwhile, secret gutters capture and drain away water that runs sideways off the tiles for enhanced water management. Flashings can be made of materials like lead or glass reinforced plastic (GRP), adding flexibility to their application.

In summary, while soakers excel in their compatibility with double-lapped products, flashings provide a wider range of options for different roofing materials. Soakers ensure a watertight seal and support, while flashings offer versatile protection against water flow and debris buildup. Understanding the differences between these two components is crucial in selecting the right solution for your roofing needs.
