Roof Flashing Repair Near Cold Spring Harbor

What is Roof Flashing?

Roof flashing is a thin product – usually a galvanized steel – that our guys will use in order to direct water away from the essential places of the roof. Frequently, it is wherever the roof plan joins a vertical surface like a dormer or a wall. The flashing is built to surround the features of the roof, like chimneys, vents and skylights. Water should then run down the side of the flashing and wind up getting dispersed to the shingles instead of finding its way onto the roof deck. Without the roof flashing against those walls, water would slowly trickle into the space between the roof and wall and even potentially into the house. So, what do you do when you find yourself needing new roof flashing installed? Knowing the different kinds as well as the practices to implement might be smart. The main key when purchasing roof flashing is to use a sealant. There are roofing companies out there, typically of the old school variety, that uses nails while flashing. This can work, but they still can need to choose whether to nail to the roof plane or to the vertical wall itself. If the contractor decides to nail to both, the flashing could deform under the pressure from shifting wood or brick. If you opt for using nails and nail only to the roof plane or to the vertical wall – the flashing could then stay situated while the other products used in the construction contract and expand as the crazy weather comes. It is that extreme change that starts the most deterioration. If some incorrect materials are used or they are built in an improper manner, that constant expansion and contraction may lead to the materials to bend and warp, making them more brittle until it finally frees. That is why roofing cement is usually accepted as the most typically used types of roofing sealant. This is because roofing cement is meant to generate a waterproof seal. Flashing contractors may use a trowel to apply it evenly so that it adheres properly.

Continuous flashing is also known as “apron flashing” because it acts in a similar manner to an apron. It is a long, single piece of metal material that is used to shed the water off to the shingles that lay under. Base Flashing. There are some roof features, like chimneys, that require two pieces of flashing. This is to ensure that the rain always joins a flashing surface to direct it downward. Not only that, it is notoriously impossible to craft flashing around a chimney. Counter Flashing. This is placed opposite of base flashing or above the base flashing. Counter flashing completes the team with the aforementioned base flashing. Step flashing is a rectangular piece of flashing that is bent 90 degrees in the middle. It is typically used for wall flashing. In this instance, many pieces of flashing will be constructed as layers with the shingles to make sure that the water flows away from the wall.

Kickout flashing solves this issue because it is these types of flashing are used to direct water away from the wall and away into the gutter.

Copper roof flashing takes soldering well and is also malleable. Not only that, it is highly durable and tends to have a longer-lasting life. On the other hand, there is some discoloring into patina, which will vary based on the client. Copper flashing is typically found around chimneys. Steel flashing is the most popular choice for flashing. In addition to aesthetic value, it is also malleable and, when galvanized, is corrosion-resistant.

Identifying Roof Flashing & Sealant types

There are quite a few arrays of roof flashing; nearly as many as there are parts to the roof. Each roof feature requires protection, hence why there are different arrays of roof flashing. Longer pieces of continuous flashing have trouble flexing as the property contracts and expand during the changing of the seasons. If left alone, they might fray or free up and fail to keep that water out. If using longer pieces, they might have built-in expansion joints so that they might adjust as the property does. Another benefit to two-part flashing is that when the roofing products expand and contract with the harsh weather, those two pieces may displace, so the system stays secure. Step Flashing. The most modern instance for step flashing is where the roof face meets a wall. An example of this is where the dormer projects out from the roof. In a spot like this, it is entirely possible that water could flow down the wall and get past the shingles into the building off below. Plumbing vent boot flashing. To put it simply vent flashing is the type of flashing that has a cylindrical piece of flashing. This piece of flashing fits around the vent itself. These shingles are crafted over the base or the boot. The height of the boot is meant to carry water to flow around the vent. Counter-flashing is most typically used to flash chimneys and involves two pieces of flashing. The first piece (the base flashing) rests around the base of the chimney. The second system, the counter-flashing, is installed into the masonry of the chimney itself. This piece sits over the base flashing. It is meant to ensure that the water doesn’t slip in behind the base flashing. Professional company typically use counter-flashing for a litany of other purposes, but it most commonly involves a second piece of flashing that is set off from the first.

Step flashing is the way to ensure that the water is properly pushed away from the wall and that it winds up in the gutter. This is called step flashing because it is crafted in steps. This involves layers of shingles so that the water gets poured off each step and then down the roof.
