Let us begin with an initial introduction to steel flashing before examining how they help with roofing options, like steel metal roofing or corrugated sheet metal roofing. Steel flashing means installing impervious materials which are pretty light weight. The purpose of steel flashing is to prevent water from entering the roofing structure through the multiple joints. Steel flashing is also used in water resistant roofing options to serve as a barrier system. Before the advent of steel flashing, carpenters employed other methods for minimising the water that could enter the structure by angling the shingles on your roof and the chimney positions around the ridge by providing steps on the side of the chimney to keep the water away.
Protection from water affecting the structure
After the introduction of flashing products, the amount of water entering the structure through chimneys, openings in doors and windows, walls and vent pipes came down substantially. Consequently, today’s structures are significantly more durable and face minimal problems from mould
With solar panels on roofs becoming popular, it is important to understand that custom flashing can be arranged along with the solar panels to pervert the roof from leaking.
A wide range of materials to choose from
Steel is not the only material employed in flashing. You can choose impregnated paper flashings, rubber, plastic or other metal. Under metal flashings, you have a wide choice as between lead, aluminium, zinc alloy, stainless steel, copper and other architectural metals. Coated metal such as Galvalume, polyvinylidene fluoride, anodised aluminium, coated copper and galvanised steel are also employed in flashing.
Choosing the right flashing material
Expansion joints must be provided when metal is employed in flashing. Over a period, the metal flashings tend to contract/expand apart from the risk of corrosion on account of a chemical reaction. In choosing galvanised flashing, the options lie between steel flashing and aluminium flashing. The choice between these two should be carefully made after considering various influencing factors. While Aluminium is a lightweight material, steel is significantly heavier. The budget, as well as environmental conditions, should be factored in a while making a choice. Aluminium is highly resistant to rust, flexible, and comfortable for working with, particularly for people who opt for the DIY route. Compared to steel, aluminium can be easily manipulated, and even inexperienced carpenters can do a good job working with aluminium flashes.
Steel flashing is less expensive compared to other flashing options. Galvanised steel is the second best option regarding cost and comes with a galvanised coating to cover the bare metal. With aluminium or copper, galvanised steel is also cheaper.
How galvanised steel flashing can benefit you
Galvanised steel is a popular material that is available readily for flashing. It will provide protection to the structure of homes as well the surface of the roof from damages caused by weather. Galvanised steel is also an affordable choice among flashing materials. Galvanizing is achieved by providing a coat of zinc. The coating process involves electroplating or hot dipping. Both these methods can produce the desired result. Depending on what the structure needs, there are endless options for homeowners.
Owners can also opt for roll flashing using sheets with 48 inches width when required. Galvanized nails are used for fastening the galvanised steel sheets. To keep safe from corrosion fasteners made out of other material are not used. Galvanised steel is however not recommended for use in conjunction with treated lumber or green lumber because of the potential reaction with steel.
Long life post installation
Galvanised steel becomes rigid post installation, and the shape will remain stable for long. The best use of galvanised steel flashing is in instances where certain forms and shapes are expected to be retained for long. Galvanised steel flashing can also be painted if the homeowner so desires without any adverse effect on the protection afforded by this type of flashing.
How is stainless steel flashing different
Stainless steel flashing is another favourite material that homeowners can consider. The versatility and durable are the primary factors that influence a decision by homeowners to choose this product. Stainless steel is highly resistant to rust, and corrosion and therefore suits many structures without taking into account, the surrounding environment.
The Chromium advantage
The composition of stainless steel flashing also includes chromium which aids better performance. Regarding other options available, stainless steel is established to withstand damages from the weather, thus affording longer life. However, it is important to remember that only the right type of fasteners is used in conjunction with stainless steel flashes. When you consider the reliability and durability of stainless steel flashes, it still ranks among the most affordable flashing solutions for homeowners.
Low on maintenance
Maintenance needs for stainless steel flashing are minimal which works as a great advantage for homeowners with minimum or no knowledge of carpentry work. Post installation, it is desirable to check the system once every year to ensure that there are no structural defects. These inspections can not only give a lot of peace of mind to homeowners but also ensure that any potential problem is addressed at an early stage avoiding expensive repairs later.
Finding the right service providers
Now that you have acquired all the required knowledge on different types of flashings, the next best thing to do would be finding a professional service provider who will supply the required material and also undertake installation. Ideally, homeowners should resist the temptation to go the DIY way, especially as this is not an indoor job and working on rooftops may not be everyone’s cup of tea.
