Roof Flashing Repair Near Port Jefferson Station

Roof Flashing Installation Basics

Roof flashing is a thin product – typically a galvanized steel – that our guys will use in order to direct water away from the critical places of the roof. Typically, 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 off 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 property. So, what do you do when you find yourself needing new roof flashing installed? Knowing the different styles as well as the techniques to implement might be smart. The main key when purchasing roof flashing is to use a sealant. There are roofing companies out there, typically of the old school variety, that uses nails while flashing. This could work, but they still could 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 opt for using nails and nail only to the roof plane or to the vertical wall – the flashing will then stay affixed while the other materials used in the construction contract and expand as the harsh weather comes. It is that bad change that initiates the most problems. If some poor materials are used or they are crafted in an uncareful manner, that constant expansion and contraction could lead to the materials to bend and warp, making them more brittle until it ultimately displaces. That is why roofing cement is generally accepted as the most typically used designs of roofing sealant. This is because roofing cement is meant to make a waterproof seal. Flashing companies may use a trowel to apply it evenly so that it adheres properly.

Metal (Steel/Copper) 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 shed the water off 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 meets a flashing surface to direct it downward. Not only that, it is notoriously impossible 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 generally used for wall flashing. In this instance, several pieces of flashing will be engineered 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 insure this area, which is a essential area 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 seep off the roof without doing damage to the property or causing a pesky leak that will do further destruction to the roof or home. 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 arrays of flashing are used to direct water away from the wall and away 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 frequently 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 property owner. Copper flashing is most commonly 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 crew look into this so that you will be covered in the event that a product is against code.

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 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 could fray or move 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 crazy weather, those two pieces will lift, so the system stays secure. Step Flashing. The best fitting instance for step flashing is where the roof face abuts 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 down below. Plumbing vent boot flashing. To put it simply vent flashing is the kind 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 disperse 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 system, 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 seep in behind the base flashing. Professional pros generally 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 might learn to supply that roof flashing, you need to understand the three primary systems that are involved. Each one is special and may be suitable for different areas of the roof. There are also flashing types that tend to correspond with a specific system. 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 built in steps. This involves layers of shingles so that the water gets poured down each step and then off the roof.

Ultimately, the application of flashing and the application of its right sealant are meant for roof issues and protect against imperitive spots from water and other damaging elements. Those hard-to-reach sections will be the first to go without right 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 divert the water off the roof. Those tough-to-reach sections may go unnoticed by amateur roofers who will not have the knowledge or experience necessary. Having a highly-skilled roofing contractor is necessary to ensure that those critical areas do not worsen. If not handled properly, areas around vents or the chimney could have a pooling of water. This water may do damage to spots of the roof, creating discoloration and even leaks. Those unwelcome leaks can be a really critical spot if left unchecked, potentially causing structural problems if left unchecked.
