Roof Flashing Repair Near New Hyde Park

What is Roof Flashing?

Roof flashing is a thin product – usually a galvanized steel – that our roofing contractors will use in order to direct water away from the imperitive sections of the roof. Usually, 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 pushed to the shingles instead of finding its way onto the roof deck. Without the roof flashing against those walls, water would slowly overflow 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 systems to implement can be smart. The main key when buying 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 could work, but they still may 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 situated while the other products used in the construction contract and expand as the extreme weather comes. It is that inclement change that causes the most problems. If some incorrect materials are used or they are engineered in an erroneous manner, that constant expansion and contraction will lead to the materials to bend and warp, making them more brittle until it eventually displaces. That is why roofing cement is generally accepted as the most most commonly used types of roofing sealant. This is because roofing cement is meant to produce its waterproof seal. Flashing contractors may use a trowel to apply it evenly so that it adheres properly.

Continuous Roof Flashing

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 away to the shingles that lay concealed. Base Flashing. There are some roof features, like chimneys, that require two pieces of flashing. This is to ensure that the rain always abuts 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 usually used for wall flashing. In this instance, several pieces of flashing will be constructed 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 produce 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 insure this area, which is a vital 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 destruction to the roof or residence. Roofing company generally 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 arrays 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 products that were lead-coated. Now, flashing companies throughout North America have switched to one of three products. 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 a lasting life. On the other hand, there is some discoloring into patina, which can vary based on the homeowner. 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 company look into this so that you may be covered in the event that a material is disallowed.

Step Roof Flashing Sealants

There are quite a few styles of roof flashing; nearly as many as there are parts to the roof. Each roof feature requires safeguarding, hence why there are many 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 will 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 will flex as the residence does. Another benefit to two-part flashing is that when the roofing materials expand and contract with the severe weather, those two pieces can dislodge, so the system stays secure. Step Flashing. The most beneficial 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 crafted 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 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 seep in behind the base flashing. Professional technicians generally 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. Before you will learn to construct that roof flashing, you need to understand the 3 primary methods that are involved. Each one is different and can be suitable for different sections of the roof. There are also flashing types that tend to correspond with a specific method. 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 down each step and then off the roof.

Ultimately, the installation of flashing and the application of its correct sealant are meant for roof issues and fight vital sections from water and other damaging elements. Those hard-to-reach spots may be the first to go without proper 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 deliver the water off the roof. Those tough-to-reach spots can go unnoticed by amateur roofers who will not have the knowledge or experience necessary. Having a certified roofing contractor is necessary to ensure that those troublesome areas do not worsen. If not handled properly, areas around vents or the chimney could have a pooling of water. This water could do damage to areas of the roof, creating discoloration and even leaks.
