Roof Flashing Repair Near Centereach

What is Roof Flashing?

Roof flashing is a thin material – most commonly a galvanized steel – that our guys will use in order to direct water away from the critical places of the roof. Most commonly, it is wherever the roof plan meets 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 seep into the space between the roof and wall and even potentially into the home. So, what do you do when you find yourself needing new roof flashing repaired? Knowing the different kinds as well as the practices to implement can be wise. The main key when purchasing roof flashing is to use a sealant. There are roofing roofing companies out there, usually of the old school variety, that uses nails while flashing. This will work, but they still can need to choose whether to nail to the roof plane or to the vertical wall itself. If the contractor 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 could then stay affixed while the other materials used in the construction contract and expand as the harsh weather comes. It is that harsh change that causes the most damage. If some shoddy materials are used or they are built in an erroneous manner, that constant expansion and contraction could lead to the products to bend and warp, making them more brittle until it ultimately moves. That is why roofing cement is usually accepted as the most most commonly used designs of roofing sealant. This is because roofing cement is meant to make a waterproof seal. Flashing contractors may 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 disperse the water away 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 difficult to install 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 frequently 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 make 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 essential spot 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 bleed off the roof without doing damage to the house or causing a pesky leak that could do further destruction to the roof or property. Roofing pros 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 designs of flashing are used to direct water away from the wall and away into the gutter. There are also a few different roofing materials 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 a longer-lasting life. On the other hand, there is some discoloring into patina, which might 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 can require a specific flashing material. Have your roofing team look into this so that you will be covered in the event that a product is against code.

Step Flashing & Sealant products

There are quite a few styles of roof flashing; nearly as many as there are parts to the roof. Each roof feature requires protection, hence why there are different types 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 could fray or uplift and fail to keep that water out. If using longer pieces, they will have built-in expansion joints so that they might adjust as the structure does. Another benefit to two-part flashing is that when the roofing products expand and contract with the crazy weather, those two pieces could move, so the system stays secure. Step Flashing. The most modern 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 off 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 built over the base or the boot. The height of the boot is meant to divert 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 flow in behind the base flashing. Professional technicians most commonly 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 will learn to supply that roof flashing, you need to understand the 3 primary methods that are involved. Each one is special and might be suitable for different spots of the roof. There are also flashing styles that tend to correspond with a specific technique. 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 constructed in steps. This involves layers of shingles so that the water gets poured off each step and then down the roof.

Ultimately, the application of flashing and the application of its appropriate sealant are meant for roof issues and fight imperitive places from water and other damaging elements. Those hard-to-reach sections could be the first to go without proper flashing, so it is crucial for the life of your roof that you have to flash that will expand and contract with the elements and move the water off the roof. Those tough-to-reach areas will go unnoticed by amateur roofers who can not have the expertise or skills necessary. Having a highly-skilled roofing contractor is necessary to ensure that those critical spots do not worsen. If not handled properly, spots around vents or the chimney could have a pooling of water. This water might do damage to areas of the roof, creating discoloration and even leaks.
