Roof Flashing Installation Basics

Roof flashing is a thin product – most commonly a galvanized steel – that our specialists will use in order to direct water away from the important areas of the roof. Typically, it is wherever the roof plan abuts a vertical surface like a dormer or a wall. The flashing is installed to surround the features of the roof, like chimneys, vents and skylights. Water should then run off the side of the flashing and wind up getting dispersed to the shingles instead of finding a way onto the roof deck. Without the roof flashing against those walls, water would slowly permeate into the space between the roof and wall and even potentially into the structure. So, what do you do when you find yourself needing new roof flashing installed? Knowing the different kinds as well as the techniques to implement can be valuable. The main key when getting roof flashing is to use its sealant. There are roofing companies out there, usually of the old school variety, that uses nails while flashing. This may work, but they still will need to choose whether to nail to the roof plane or to the vertical wall itself. If the company opts to nail to both, the flashing could deform under the pressure from shifting wood or brick. If you choose using nails and nail only to the roof plane or to the vertical wall – the flashing could then stay situated while the other materials used in the construction contract and expand as the extreme weather comes. It is that turbulent change that initiates the most damage. If some poor products are used or they are constructed in an imperfect manner, that constant expansion and contraction can lead to the products to bend and warp, making them more brittle until it finally uplifts. That is why roofing cement is frequently accepted as the most frequently used styles of roofing sealant. This is because roofing cement is meant to produce its waterproof seal. Flashing contractors can 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 product that is used to remove the water off to the shingles that lay underneath. Base Flashing. There are some roof features, like chimneys, that require two pieces of flashing. This is to ensure that the rain always meets a flashing surface to direct it downward. Not only that, it is notoriously impossible to lay down 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 generally used for wall flashing. In this instance, numerous pieces of flashing will be installed as layers with the shingles to make sure that the water flows away from the wall.

Roofing company usually need something to bridge the gap where the step flashing comes to an end and where the gutter begins. Kickout flashing solves this issue because it is these kinds of flashing are used to direct water away from the wall and off into the gutter. There are also some different roofing products that you need to be aware of. In the past, this would be lead or materials that were lead-coated. Now, flashing companies throughout North America have switched to one of three materials. Aluminum flashing is most commonly easy for roofers to form and it is also quite lightweight. There is one thing to note, however: aluminum has to be coated if it is going to be used with masonry and concrete since plain aluminum degrades and reacts when it makes contact with alkaline surfaces. Copper roof flashing takes soldering well and is also malleable. Not only that, it is highly durable and tends to have an enduring life. On the other hand, there is some discoloring into patina, which might 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. Your town’s building codes that will require a specific flashing material. Have your roofing corps look into this so that you may be covered in the event that a material is disallowed.

Step Flashing & Sealant materials

There are quite a few designs of roof flashing; nearly as many as there are parts to the roof. Each roof feature requires insurance, hence why there are different arrays of roof flashing. Longer pieces of continuous flashing have trouble flexing as the house contracts and expand during the changing of the seasons. If left alone, they could fray or move and fail to keep that water out. If using longer pieces, they could have built-in expansion joints so that they may adjust as the property does. Another benefit to two-part flashing is that when the roofing materials expand and contract with the bad weather, those two pieces will dislodge, so the system stays secure. Step Flashing. The most ideal instance for step flashing is where the roof face joins 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 off the wall and get past the shingles into the building down 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 installed over the base or the boot. The height of the boot is meant to remove water to flow around the vent. Counter-flashing is most frequently 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 part, the counter-flashing, is installed into the masonry of the chimney itself. This piece is placed over the base flashing. It is meant to ensure that the water doesn’t get in behind the base flashing. Professional company generally use counter-flashing for a litany of other purposes, but it typically involves a second piece of flashing that is set off from the first. Before you could learn to construct that roof flashing, you need to understand the three primary techniques that are involved. Each one is different and could be suitable for their own sections of the roof. There are also flashing designs that tend to correspond with a specific practice. Step flashing is the way to ensure that the water is properly dispersed away from the wall and that it winds up in the gutter. This is called step flashing because it is engineered in steps. This involves layers of shingles so that the water gets poured off each step and then off the roof.
