If you have bought a new house and the slopes of the roof are not effective enough to drain out all the rainwater, then you have no choice but to effectively shingle the roof valley.
In other words, constructing valleys of slopes requires precision.
What does it Mean to Shingle a Valley?
To shingle, a valley is a process of creating the right slopes of the roof valleys. It is the most effective way to construct the roof so that water does not accumulate on it and immediately drains out protecting it from damage. In addition, the entire house can get defective due to seepage if the slopes are not constructed properly. In other words, not just the roof but also other parts of the house may require repair in the long run. Finally, to put it in simple terms, to shingle a valley means to create the right slopes and attach the different pieces to make a good and durable roof. In other words, it waterproofs the roof, thereby ensuring the durability and longevity of the house.
- Method to waterproof a roof. In turn, save the house from seepage and other related defects.
- Shingle the process of creating the right slopes by attaching the different pieces. This process manufactures correct slopes on a roof.
- If the slopes are not proper then the water accumulates on it leading to seepage. The seepage can lead to defects in the entire house.
- Repair a faulty roof immediately. Or else it may lead to a situation of no-return further damaging the house.
How to Create a Valley on the Roof?
To begin with, it is important to understand the purpose of creating a valley on the roof. The valley works as a drainage channel on the roof of the building. It helps in rainwater slipping out of the house so that it does not accumulate and create seepage. This is constructed as a rivulet channel below the slopes, and at either the same level or a lower level than the roof. Different materials are used for constructing such a valley. It could be made of either metal, wood, or it may just be left open as a cemented channel. The valley protects the house from dampness and in turn seepage, and finally damage.
- Valley constructed on the roof to channel the water out of the slopes.
- Made below the slopes, at either the same or lesser height than the roof.
- The valley helps in draining out the water and in turn, saves the house from seepage.
How do You Shingle a Valley?
There are 3 options available to shingle a valley effectively. Each of them serves the same purpose to protect the house from seepage. However, the use of the technique differs on the basis of the materials used and the climatic conditions of the place in which you have to shingle the valley.
The 3 different ways to shingle a valley are open, close-cut, and woven methods.
1. Shingle a Valley with Woven Method
To construct such a valley, one has to weave the shingles together. This method relies on the weave pattern to avoid the water from accumulating. In other words, in this process, a valley is shingled without using cement. The shingles are pushed under the valley and weaved together closely. This leaves no gap for water to filter in. To achieve this perfection, shingles are nailed at close range.
Finally, it is also important to note the drawbacks this kind of process carries. Firstly, the process is slow. For instance, it can be a long procedure to weave each shingle and ensure the gaps are completely sealed. Secondly, to repair any defect can be difficult as this requires removing a couple of shingles and re-weaving them. Therefore, though initially, they come cheap, in the long run, you may end up spending more money on their repairs.
- This process requires weaving the shingles together.
- Nails help in stitching the shingles and keeping them in place.
- In the long run, this might hit your budget hard.
- Repairing them is a long and slow process.
2. Shingle a Valley with Close-Cut Process
This is a fast and clean way to shingle a valley. Whole shingles are used to construct a valley by this process. In other words, cut pieces will not give a clean and perfect look to the roof. In addition, shingles are overlapped over each other. This gives a neat and even look. The only drawback with such a process is that with time there is a likelihood of the shingles corroding. Therefore, over the years, they may require to be repaired.
- The close-cut process gives a clean and neat look.
- Here shingles are laid to overlap each other.
- One drawback is that the shingles may corrode with time.
3. Open Valley Process to Shingle a Valley
Leave open a line of metal to shingle a valley if you are using the open valley process for this purpose. The metallic line helps in making the shingles more durable. Therefore valleys constructed with this process have better longevity. For instance, the metal layering on the sides of the shingles helps shed water faster. Therefore, the longevity of the shingles increases as a result.
- In this process of manufacturing, use a metal sheet to layer the sides of the shingles.
- The metal helps in increasing the longevity of the shingles.
- Metal speeds up the process of filtering out water.
How do You Shingle a Valley with 3-Tab?
Using 3-Tab shingles to construct a valley is a very common method in modern houses. To create a valley using 3-Tabs, you need a hammer, nails, roofing cement, chalk, 36-inch white flashing material, and a knife. To begin with, you need to unroll the white flashing material and cut it to the required size over the valley. Then, secure the flashing material with nails. Extend the 3-Tab shingles over the valley onto the roof’s plane. Further, secure the 3-Tab shingles with nails over the valley, after cutting the loose shingles with a knife.
- Use chalk to mark the lines over which the flashing material has to be laid over the valley perfectly.
- Cut the material to precision with a knife. Secure the material over the valley and the shingles with nails.
Advantages of Shingling a Valley
Shingling a valley on your roof is important to live tension-free in all weather. In other words, it has some inherent advantages. Since the valley gives a natural flow to the water during the rainy season or when it snows, shingling it makes your roof weatherproof. If there is no accumulation of water on the roof there will not be any seepage. In turn, the house will look good. In addition, you will save money and harassment of doing regular repairs to your house.
- Shingling waterproofs the roof.
- There will be no seepage if you shingle a valley on the roof.
- Water will not accumulate on the roof.
- Effectively, there will be no requirement to carry out any repairs.
Finally, Some Tips on how to Shingle a Valley
To achieve the perfect result there are some precautions that you must take. In other words, since the purpose is to ensure the safety and longevity of your home, this work needs to be executed with precision. To ensure the best results, here are a few tips you must keep in mind.
- Protect the metal shingles with a metal flashing. Ensure the flashing is wide enough to cover both sides.
- The flashing must be thin. Aluminum is the best material for this purpose. In other words, it should be easy to bend.
- Cut all the flaps precisely with a sharp knife.
- Start laying the shingles from the bottom of the roof.
- Shingle should be flat against the roof.
- Place the shingles directly over each other.
