Roof Flashing Repair Near Sag Harbor

What is Roof Flashing?

Roof flashing is a thin material – usually a galvanized steel – that our technicians will use in order to direct water away from the imperitive spots of the roof. Typically, 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 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 house. So, what do you do when you find yourself needing new roof flashing installed? Knowing the different types as well as the methods to implement could be wise. The main key when purchasing roof flashing is to use its sealant. There are roofing roofing companies out there, most commonly of the old school variety, that uses 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 decide on using nails and nail only to the roof plane or to the vertical wall – the flashing will then stay affixed while the other products used in the construction contract and expand as the bad weather comes. It is that extreme change that starts the most complications. If some shoddy products are used or they are built in an improper manner, that constant expansion and contraction may lead to the products to bend and warp, making them more brittle until it finally moves. That is why roofing cement is generally accepted as the most typically used types of roofing sealant. This is because roofing cement is meant to generate a waterproof seal. Flashing contractors may use a trowel to apply it evenly so that it adheres properly.

Residential 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 material that is used to redirect the water off to the shingles that lay below. 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 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, multiple 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 forge 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 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 drip off the roof without doing damage to the property or causing a pesky leak that can do further damage to the roof or home. Roofing contractors 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, roofing companies throughout North America have switched to one of three products. Aluminum flashing is typically 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 could vary based on the homeowner. 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 team look into this so that you might be covered in the event that a product is not recommended.

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 different arrays 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 can fray or break and fail to keep that water out. If using longer pieces, they may have built-in expansion joints so that they might flex as the structure does. Another benefit to two-part flashing is that when the roofing products expand and contract with the extreme weather, those two pieces may move, so the system stays secure. Step Flashing. The most ideal 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 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 force 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 piece, the counter-flashing, is installed into the masonry of the chimney itself. This piece rests over the base flashing. It is meant to ensure that the water doesn’t flow in behind the base flashing. Professional company typically use counter-flashing for a litany of other purposes, but it frequently 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 3 primary plans that are involved. Each one is special and will be suitable for different spots of the roof. There are also flashing designs that tend to correspond with a specific system. 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 crafted in steps. This involves layers of shingles so that the water gets poured off each step and then down the roof.

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