To have a secure home, the condition of your roof will be an important detail to pay attention to. Without a sturdy, good-looking, and leak-proof roof, it will be difficult to enjoy the comfort of your abode. Water dripping through the ceiling can cause major problems such as interior damage and mold growth. When learning how to repair a roof valley, it is important to get the job done right in order to avoid all of these issues. Today we will be looking at the 5 steps to a secure roof when understanding how to repair a roof valley.

Choosing the Right Company Step 1

Deciding which company should repair your roof can be a tough decision to make. You need to find someone who has a reasonable price, a credible background, and will clean up after they are done with their work. Do not sacrifice the quality of the job for a cheap price. After all, you do not want to have to deal with roof issues again, which could jeopardize your free time and budget.

The contractor should have a building permit, a clear contract with you, and insurance verification to ensure warranties, and protection. Cleaning up is not guaranteed for all roof-repair companies. When choosing how to repair a roof valley, be sure the crew you hire will go through your yard with a magnet and pick up nails as well as remove scrap materials.

Preparation Step 2

As a customer, it is crucial that you are aware of what goes into the pricing of a roof repair, and how you can prepare your roof prematurely to save money. In many states, estate owners are allowed up to two layers of roofing. Therefore, you shouldn’t take off your current layer unless necessary.

On the other hand, if your current roofing has major damage or needs additional precipitation protection, it may be a good idea to strip that layer off. Getting rid of that layer gives the company the option to install ice protection and rubber that prevents leaks.

How It Works Step 3

To begin, the workers will use ladders to get on top of your roof and clear off any debris or major obstructions. Next, they will measure the width of the valley flashing which is composed of sheet metal. If removing your current layer of roofing, they will start at the top of the valley and pry the old shingles out with a tool called a nail bar.

Working from the highest point, they will remove around eight inches of shingles at a time, until they get down to the bottom of the valley. After the old layer is stripped away, they will begin to place waterproof shingle underlayment. This is merely the first installation step in how to repair a roof valley.

Once the waterproof shingle underlayment is laid down, there are multiple ways of placing the shingles over the valley. If using metal, the company will leave that strip of metal exposed, with the singles working up to each side of it. If using shingles, there are three different ways of installing the new layer. When learning how to repair a roof valley, each of these methods should be understood.

Three Different Methods Step 4

Long Island Valley, Woven Valley, and Closed Cut Valleys are the three different variations of shingle valley roof repairs. Each variation has its pros and cons and should be considered by you and your contractor. The Long Island Valley is where the company will use a strip of shingles that sits on top of the valley. It may take longer due to the extra rubber applied between the roof and the valley shingles, but it will provide a double layer protection.

The Woven Valley is where shingles from each side will overlap and be layered on top of each other. This also will take more time than usual and create a double layer. However, Woven Valleys are also prone to disformity due to the air pockets that can form in between the layers of shingles. It may cause your roof to look like it has a slight bulge, and could allow precipitation to slowly cause damage.

When shingles from each side are cut in order to fit together when meeting at the valley, it is called a Closed Cut Valley. This often looks good aesthetically and takes a shorter amount of time compared to the other variations, but lacks extra protection because it is only one layer total.

Prevent Further Damage Step 5

After your roof is completely finished, besides admiring its new look, you should be considering how you can keep it from being damaged again in the near future. One of the most common ways this can be done is by adding extra insulation to your roof. An additional layer of insulation will help reduce long-term deterioration from precipitation.
Another method is to make sure your gutters do not get clogged for long periods of time. Keep cleaning them out when necessary. A method that is a bit more radical is to cut down any major trees close to your house. This  way, you ensure they will not fall on top of your roof in case of a major storm.

Overview and Final Thoughts

Now that you have read about how to decide who to hire for your roof repair, how it works, different options you have, and how to prevent damage in the future, we hope you can see your roof repaired and maintained the right way. Without learning how to repair a roof valley, a building owner could end up having more trouble than they need to. Getting a roof repair already costs enough time and money. Therefore, you should get the job done the right way in the first place so you don’t have to go through it again.
