Introduction

When it comes to construction and building materials, two common methods used are flashing and keeping down. Both techniques serve important purposes in ensuring the structural integrity and longevity of a building. In this article, we will compare the attributes of flashing and keeping down to understand their differences and similarities.

Definition

Flashing is a thin piece of material, typically metal, that is installed to prevent water from penetrating a structure. It is commonly used around openings such as windows, doors, and chimneys to redirect water away from vulnerable areas. Keeping down, on the other hand, refers to the process of securing roofing materials in place to prevent them from being lifted or displaced by wind or other external forces.

Materials

Flashing is typically made of materials such as aluminum, copper, or galvanized steel. These materials are chosen for their durability and resistance to corrosion. Keeping down, on the other hand, may involve using fasteners such as nails, screws, or adhesive to secure roofing materials in place. The choice of materials for keeping down will depend on the type of roofing material being used and the specific requirements of the project.

Installation

Flashing is installed by bending the material to fit the contours of the structure and then securing it in place with fasteners. Proper installation of flashing is crucial to ensure that water is effectively redirected away from vulnerable areas. Keeping down, on the other hand, involves securing roofing materials in place using fasteners or adhesive. This process requires careful attention to detail to ensure that the materials are securely attached and will not be lifted or displaced.

Function

The primary function of flashing is to prevent water from entering a structure and causing damage. By redirecting water away from vulnerable areas, flashing helps to protect the integrity of the building and prolong its lifespan. Keeping down, on the other hand, ensures that roofing materials remain in place and do not become dislodged by wind or other external forces. This helps to maintain the structural integrity of the roof and prevent leaks or other damage.

Maintenance

Flashing may require periodic maintenance to ensure that it remains effective in preventing water penetration. This may involve inspecting the flashing for signs of damage or wear and replacing it as needed. Keeping down, on the other hand, may also require maintenance to ensure that roofing materials remain securely in place. This may involve checking fasteners for tightness and replacing any that have become loose or damaged.

Cost

The cost of flashing will depend on the material used and the size of the project. Materials such as copper may be more expensive than aluminum or galvanized steel. The cost of keeping down will also vary depending on the type of fasteners or adhesive used and the size of the project. In general, keeping down may be a more cost-effective option compared to flashing, especially for smaller projects.

Conclusion

In conclusion, flashing and keeping down are both important techniques used in construction to ensure the structural integrity and longevity of a building. While flashing is primarily used to prevent water penetration, keeping down is used to secure roofing materials in place. Both techniques require careful installation and maintenance to ensure their effectiveness. By understanding the differences and similarities between flashing and keeping down, builders and contractors can make informed decisions about which method is best suited for their specific project.
