Roof Curb Flashing Materials and Accessories for Effective Drainage

Roof curb flashing is a crucial component of a building's exterior, and selecting the right materials and accessories can make a big difference in effective drainage.

A roof curb is a raised edge around a roof opening, such as a vent or skylight, and flashing is used to prevent water from seeping behind the curb.

For effective drainage, roof curb flashing materials should be able to withstand harsh weather conditions, including heavy rain and intense sunlight.

Roof curb flashing materials and accessories come in a variety of types, including metal, plastic, and rubber, each with its own set of benefits and drawbacks.

Metal roof curb flashing is a popular choice due to its durability and ability to withstand extreme weather conditions, and it can be made from materials such as aluminum or galvanized steel.

Plastic roof curb flashing is a cost-effective option and is often used for smaller roof openings, but it may not be as durable as metal flashing.

DCI's roof curb flashing options are designed to provide a strong resistance to weather, ozone, and ultra-violet light. Their Dektite flashing is made of a long-life, weatherproof EPDM rubber that conforms to most roof pitch and panel configurations.

You can choose from various types of flashings, such as Dektite, Dek-Cap, and Dekstrip. Each has its own unique features, such as pre-formed Dek-Cap flashings that reduce installation time, or Dekstrip flashings that feature heat weld and 25% stretch.

Prefabrication is also a benefit of roof curb flashings, as it allows for welding in a factory-controlled environment, resulting in a better-looking finished product and improved watertight integrity. This process also reduces rooftop labor.

Here are some uses for rooftop curbs:

When you're looking to get the most out of your rooftop, you need to consider the various uses it can serve. One of the most practical uses for a rooftop curb is to provide a secure and stable base for hatches, which give you easy access to the roof.

A roof curb can also be used to mount skylights and smoke vents, allowing natural light in and harmful gases to escape. This is especially important for buildings that require ventilation.

Exhaust fans need a sturdy platform to operate effectively, and a roof curb provides the perfect solution. It's like having a solid foundation for your equipment.

HVAC units also need a secure and level platform to sit on, which is exactly what a roof curb offers. This helps to protect your investment and ensures your equipment operates efficiently.

Here are some of the key uses for rooftop curbs:

Roof curb flashings can be a crucial part of maintaining a watertight seal on your metal roof. The Dektite flashing is made of a long-life, weatherproof EPDM rubber that resists maximum weather, ozone, and ultra-violet light.

This type of flashing is easy to install and can be attached to various roof materials, including steel, aluminum, copper, plastic, fiberglass, and wood. The installation process typically takes less than 10 minutes and can be completed in five easy steps.

One of the benefits of prefabrication is that welding is completed in a factory-controlled environment, providing a better-looking finished product with watertight integrity. This process also reduces rooftop labor.

Dek-Cap flashings are a great option for metal roof curbs, as they are constructed of thermal elastometer rubber and contain corrosion-resistant aluminum bases that conform to roof panels. They are pre-formed to reduce installation time and work with both left- and right-handed seams.

The Dekstrip flashing is an expandable edged flashing that features heat weld and contains 25% stretch. This type of flashing is lightweight, compact, and eliminates screw hole elongation.

Duro-Last prefabricated drain boots can be used in most circular roof drains, and they're designed with a reinforced membrane that ensures a long-lasting, watertight flashing.

To ensure a watertight installation, a caulk sealant is applied to the outside of the drain boot before it's installed, and the drain is sealed with an expandable composite drain ring inside the drain after installation.

It's recommended to install dome strainers over all drains to catch debris and leaves, which can prevent clogs and damage to the roof.

The Duro-Last prefabricated drain boots are available in custom and standard sizes, so you can choose the one that fits your specific needs.
