ABOUT ROOF VALLEY REPAIRS AND INSTALLATION?
A roof valley refers to a spot in the roof wherein two sections of sloping roofing meet. This is an area designed for water to efficiently flow down your roof and into your guttering. Some valleys may look like a seamless joint with waterproofing underneath, and other valleys use roof valley flashing with a small channel between the roofing sections to ensure an efficient flow of water and waterproof seal between the two sections of roof. If this gets blocked then you might need our Melbourne roof repair service. If this is still hard to picture, think of it as the inside corners on your roof, or internal folds.
TYPES OF ROOF VALLEYS
What is a valley on a roof? As Melbourne’s leading roof repair experts, understanding the different elements of a roof is our expertise. You might have not heard of a valley in a roof before, so it is still important to know what it is and the different types of valleys that can be used on your home’s roof.
OPEN VALLEYS ON A ROOF
An open valley is one that is not covered by roofing material and exposed to the open area on your roof. This is the most common roof valley across Melbourne and would most likely require roof repairs over time. Do not worry – although they are open and you may think having an exposed valley as a potential to leaks and problems, an open valley is actually a great solution for many properties. When installed properly with the appropriate roof valley flashing and materials, open valleys are completely waterproof and sealed.
CLOSED VALLEYS ON ROOFS
Closed valleys uses roofing materials that is cut to ensure the planes of a sloping roof meet to create a seamless join that does not require a channel in-between. Many people choose to have a closed valley in a roof purely because of the aesthetic appeal.
CLOSED VALLEY VS OPEN VALLEY ROOFS
When used for the right applications and installed correctly, both open and closed valleys are great options for residential and commercial properties. When it comes down to cost, open valley roofs can be more expensive as they require additional materials, especially if you have a significant amount of valleys on your roof. Although closed valleys may seem like the better option at a glance, they also have their drawbacks. With the closed valley design, there is only a single waterproofed layer between the rain coming down and the internal area of your roof. As open valleys require extra flashing in between the two roof slopes, they also have an added level of waterproofing. More often than not, metal roof valley flashing is used which is impermeable by water and also helps it move faster down your roof. This is an added benefit for low pitched roofs that struggle with water collection. Closed valleys are also considered more aesthetically appealing as they do not require sheet metal valleys which may break up the overall look if you use materials other than sheet metal for your roofing. That being said, many Australians have metal roofs and there are many companies that have a wide range of colours and finishes to suit your needs. Especially when most homeowners and builders are using colorbond steel.
COMMON ROOF VALLEY PROBLEMS
Why does valley’s on a roof have leaves in it? A big issue. The biggest problem for open valley roofs is leaves collecting in them. When leaves and debris build up in a valley, they prevent water from efficiently flowing down the channel and off your roof. As this progresses and more debris and water accumulate the flashing weakens and corrodes as a result. With the flashing compromised, water might penetrate into your roof and leaks could occur. If this is found to be the case, the flashing will need to be replaced. This issue occurs especially for houses under or near large trees as leaves can easily fall and collect in the valleys.
That’s why it is important to regularly inspect your roof and gutters to check for any issues. We always recommend prudent maintenance like cleaning your gutters and checking your roof at least once per year. It may take months or years for these issues to be noticed without inspection as the leaks and corrosion progress over time, rather than a large roof leak presenting itself immediately.
WOUKD WE NEED VALLEY FLASHING ON MY ROOF?
Flashing’s is a very important part of roofing that works to waterproof areas of your roof. It protects your roof and home from issues of moisture intrusion. Roof Flashings is the pieces of impervious material that are placed on your roof to prevent moisture from getting through. One of the main applications for flashing is at joins in roof materials, split levels and edges of valleys. Without flashings, moisture could penetrate the join between the two roof sections and get inside your roof, this would then result in a whole host of issues for you. What is a valley on a roof without flashings or being waterproofed? Another big problem. This is why we are your local roof repair experts near Boroondara.
