Without proper flashing, water can easily enter through gaps and crevices, leading to significant damage. The flashing should be installed before the sheathing, creating a continuous waterproof barrier. A common method involves installing flashing around the perimeter of the window or door opening, extending up and over the top and down the sides, creating a sort of “drip edge”.

This prevents water from running down the wall and seeping behind the siding. The flashing should overlap the sheathing by several inches, and all seams should be sealed with a high-quality sealant to prevent water penetration.

Flashing Tape Application

Flashing tape, a self-adhesive waterproof membrane, is used to seal seams and joints in the flashing system, ensuring complete water tightness. It’s applied over the overlapping edges of flashing materials, creating a durable and flexible seal that can withstand movement and expansion/contraction due to temperature changes. The tape should be firmly pressed down to ensure proper adhesion and eliminate any air pockets.

Proper application of flashing tape prevents water from seeping into the wall system through even the smallest gaps. Many high-performance flashing tapes incorporate a butyl rubber adhesive for superior durability and water resistance.

J-Channel Installation

J-channel is an L-shaped piece of metal used to provide a finished edge for siding around windows and doors, and also as a starting point for vertical siding runs. It is typically made of aluminum or vinyl and is installed over the flashing, providing a clean, neat appearance. The J-channel is secured to the sheathing using nails or screws, ensuring a secure fit.

Proper alignment is crucial for a professional finish. The siding then fits neatly into the channel, creating a watertight seal. The use of J-channel simplifies installation and enhances the overall aesthetic appeal of the finished siding.

Methods for Securing Sheathing
