Roof Flashing Repairs 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 places of the roof. Usually, it is wherever the roof plan abuts 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 directed to the shingles instead of finding its 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 property. So, what do you do when you find yourself needing new roof flashing installed? Knowing the different styles as well as the practices to implement can be useful. The main key when purchasing roof flashing is to use a sealant. There are roofing companies out there, most commonly of the old school variety, that still use nails while flashing. This could work, but they still will need to choose whether to nail to the roof plane or to the vertical wall itself. If the contractor considers to nail to both, the flashing could deform under the pressure from shifting wood or brick. If you consider using nails and nail only to the roof plane or to the vertical wall – the flashing will then stay situated while the other products used in the construction contract and expand as the crazy weather comes. It is that harsh change that initiates the most breakages. If some bad materials are used or they are crafted in an imperfect manner, that constant expansion and contraction may lead to the products to bend and warp, making them more brittle until it eventually dislodges. That is why roofing cement is usually accepted as the most most commonly used types of roofing sealant. This is because roofing cement is meant to create a waterproof seal. Flashing techs might use a trowel to apply it evenly so that it adheres properly.

Metal (Steel/Copper) Roof Flashing arrays

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 remove 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 construct 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 most commonly used for wall flashing. In this instance, various pieces of flashing will be crafted 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 create 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 critical location 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 fall off the roof without doing damage to the residence or causing a pesky leak that can do further destruction to the roof or residence. Roofing technicians most commonly 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 types of flashing are used to direct water away from the wall and down 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 products that were lead-coated. Now, roofing contractors throughout North America have switched to one of three products. Aluminum flashing is usually 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 a lasting life. On the other hand, there is some discoloring into patina, which can 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 can require a specific flashing material. Have your roofing company look into this so that you might be covered in the event that a product is not recommended.

Step Flashing & Sealant materials

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 myriad kinds of roof flashing. Longer pieces of continuous flashing have trouble flexing as the home contracts and expand during the changing of the seasons. If left alone, they might fray or displace and fail to keep that water out. If using longer pieces, they should have built-in expansion joints so that they will adjust as the property does. Another benefit to two-part flashing is that when the roofing materials expand and contract with the harsh weather, those two pieces might lift, so the system stays secure. Step Flashing. The best, newest 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 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 constructed over the base or the boot. The height of the boot is meant to shed 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 is placed over the base flashing. It is meant to ensure that the water doesn’t seep in behind the base flashing. Professional contractors frequently use counter-flashing for a litany of other purposes, but it usually involves a second piece of flashing that is set off from the first. Before you can learn to craft that roof flashing, you need to understand the three primary practices that are involved. Each one is unique and can be suitable for different spots of the roof. There are also flashing kinds that tend to correspond with a specific practice. Step flashing is the way to ensure that the water is properly redirected away from the wall and that it winds up in the gutter. This is called step flashing because it is built in steps. This involves layers of shingles so that the water gets poured off each step and then off the roof.

Ultimately, the installation of flashing and the application of its proper sealant are meant for roof issues and protect against important areas from water and other damaging elements. Those hard-to-reach spots could be the first to go without correct flashing, so it is paramount 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 sections can go unnoticed by amateur roofers who can not have the expertise or history necessary. Having a highly-trained roofing contractor is necessary to ensure that those critical spots do not worsen. If not handled properly, places around vents or the chimney could have a pooling of water. This water will do damage to places of the roof, creating discoloration and even leaks. Those probable leaks should be a really imperitive place if left unchecked, potentially causing structural affliction if left unchecked. A right roof flashing might do wonders for insuring your roof from water complications and unnecessary wear and tear to those imperitive sections on your roof.
