Roof Flashing Installation Basics

Roof flashing is a thin material – typically a galvanized steel – that our pros will use in order to direct water away from the crucial areas of the roof. Frequently, it is wherever the roof plan abuts a vertical surface like a dormer or a wall. The flashing is constructed 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 directed to the shingles instead of finding its way onto the roof deck. Without the roof flashing against those walls, water would slowly drip 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 types as well as the practices to implement could be useful. The main key when installing roof flashing is to use a sealant. There are roofing companies out there, most commonly of the old school variety, that uses nails while flashing. This may work, but they still can need to choose whether to nail to the roof plane or to the vertical wall itself. If the pro chooses 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 might then stay in place while the other materials used in the construction contract and expand as the extreme weather comes. It is that severe change that starts the most damage. If some bad materials are used or they are installed in an incorrect manner, that constant expansion and contraction can lead to the materials to bend and warp, making them more brittle until it eventually dislodges. That is why roofing cement is most commonly accepted as the most most commonly used styles of roofing sealant. This is because roofing cement is meant to make its waterproof seal. Flashing techs might use a trowel to apply it evenly so that it adheres properly.

Kickout Roof Flashing Types

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 redirect the water down 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 joins a flashing surface to direct it downward. Not only that, it is notoriously difficult 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 usually used for wall flashing. In this instance, numerous pieces of flashing will be built as layers with the shingles to make sure that the water flows away from the wall. Skylight Flashing. There are some skylight manufacturers that include flashing with their product, but others will require you to generate it or purchase it separately. Knowing which option you have beforehand is helpful. Valley Flashing. Any open valleys on your roof have metal flashing in order to safeguard this area, which is a essential place of the roof. ‘Drip edge flashing’ is laid down at the edge of the roof. Drip edge flashing is a thin metal flashing that allows water to overflow off the roof without doing damage to the property or causing a pesky leak that can do further damage to the roof or structure. Roofing company frequently 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 designs of flashing are used to direct water away from the wall and down into the gutter. There are also some different roofing materials that you need to be aware of. In the past, this would be lead or materials that were lead-coated. Now, roofing companies throughout North America have switched to one of three materials. Aluminum flashing is generally 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 could vary based on the customer. Copper flashing is usually 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 could require a specific flashing material. Have your roofing team look into this so that you can be covered in the event that a material is disallowed.

Identifying Roof Flashing & Sealant styles

There are quite a few kinds of roof flashing; nearly as many as there are parts to the roof. Each roof feature requires safeguarding, hence why there are myriad types of roof flashing. Longer pieces of continuous flashing have trouble flexing as the structure contracts and expand during the changing of the seasons. If left alone, they could fray or warp and fail to keep that water out. If using longer pieces, they might have built-in expansion joints so that they could adjust as the home does. Another benefit to two-part flashing is that when the roofing materials expand and contract with the inclement weather, those two pieces might dislodge, so the system stays secure. Step Flashing. The most innovative 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 down the wall and get past the shingles into the building down below. Plumbing vent boot flashing. To put it simply vent flashing is the design of flashing that has a cylindrical piece of flashing. This piece of flashing fits around the vent itself. These shingles are engineered 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 commonly 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 piece, 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 flow 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 may learn to supply that roof flashing, you need to understand the three primary techniques that are involved. Each one is different and might be suitable for different sections of the roof. There are also flashing kinds that tend to correspond with a specific system. 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 installed in steps. This involves layers of shingles so that the water gets poured down each step and then down the roof.

Ultimately, the installation of flashing and the application of a proper sealant are meant for roof issues and defend against vital spots from water and other damaging elements. Those hard-to-reach sections will be the first to go without most apt flashing, so it is essential for the life of your roof that you have to flash that will expand and contract with the elements and convey the water off the roof. Those tough-to-reach places will go unnoticed by amateur roofers who could not have the tools or history necessary. Having a highly-trained roofing contractor is necessary to ensure that those troubled places do not worsen.
