How to Install Metal Roofing?
Installing a metal roof can cause all sorts of issues to inexperienced roofers.
While the procedure might seem rather straightforward, there are lots of things that can go array ultimately affecting the way roof stands. Furthermore, bad installation can cause future issues also affecting the longevity of the said roof.
We always recommend that you hire a professional roofing company such as ours. However, if you’re still intent on installing the roof by yourself, here are some things you need to keep in mind. Read on!
Roof preparation steps
Given that roof installation is such a big construction project, you will have to take numerous precautionary measures before you even start. Furthermore, you will have to measure everything perfectly so that thing fit. Any mistake during setup phase can cost a lot later on. It can result in you buying more material than you need or even worse, unwanted accident.
Here are some of the things to keep in mind as you begin installing a roof for your home.
- Initial measurements
Logically, the first thing you need to do is measure the roof and establish how many tiles or shingles you will need for the project. Here, you have to focus on the length and the width. After you determine these two, they have to be multiplied so you understand what kind of surface we’re talking about. Proper measurement is crucial; after you get the exact area that needs to be covered, you can give this number to a local salesman who can help you from here on out. Needless to say, you will have to climb on the roof to make the proper assessment. Also, when buying supplies, make sure to buy a bit more shingles or tiles than you actually need. Even if you go a bit overboard, they can be stored as a replacement material. However, don’t buy too many of them! Measurements should be done during dry weather. A slippery roof can pose a big hazard so make sure to avoid it.
- Safety first
Ideally, any type of roof job should be done during the summer. Even if you notice smaller leaks, you can survive most types of damage until summer. A wet roof can be really dangerous even for seasoned professionals. You will also have to rely on safety anchors. Most hardware stores have them so you can buy them at the same time as the other supplies. Once you buy them, they have to be placed on the roof. Keep in mind there are various types of anchors and oftentimes, the installation process will be different depending on what you bought. But don’t worry; they come with simple instructions that anyone can follow. They need to be properly secured before any weight is placed on them.
- Using safety harness properly
The trick to safety harness is to attach it to previously placed anchors. This provides the necessary security for the person performing the installation. Like with anchors, the process may be different depending on what kind of a harness you bought. Besides properly attaching it to anchors, the harness has also to be attached tightly to your body. This is the first thing you have to do each time you climb on the roof. Once you finish, make sure to leave it somewhere near the ladder so you can easily and quickly access it tomorrow.
- Setting up the base
The base is formed by using underlayment membrane. Place it in one of the bottom corners of your roof and start rolling it out. The membrane has to be safely attached to the roof. You can do this by using nails along the edges of the membrane. Most experts recommend that you have one nail on every 10 inches or so. While this item may not seem important at first, keep in mind that it provides a surface on which you will work and can also help with roof condensation.
- Drip edge
Drip edge is a metal flashing that is installed at the edges of the roof to help control the flow of water away from the fascia and to protect the underlying roofing components. If you don’t know what fascia is, this is a long metal board that goes along the edge of the roof. There has to be at least a 0.5-inch gap between these two. Drip edge has to have the same length as the edge of the roof; this is something you have to pay attention to when going to a hardware store. Also, when nailing drip edge, make sure to use nails that are suitable for metal.
Given that metal shingles are preferred to metal tiles, we will focus on them in this article. You can also install metal tiles but the process may be a bit different.
- Start placing shingles
Like with almost everything else when it comes to roof installation, you have to choose one of the lower corners of the roof. Installation begins thereby placing the first shingle. Be careful though as you will have to position the shingle at the bottom of the roof. You can easily notice the openings where shingles go in. Shingle should be pushed all the way to the corner so there is no space in-between. If you did it properly, shingle will simply slide in. There will be no need for any forceful movement.
- Secure the shingle
Although shingle should slide in with ease, that doesn’t mean it is properly secured. For that, you will need a hammer and nails. Given that you will be using metal shingles; you will also have to use nails of the same material. This way, you can prevent future corrosion. Keep in mind that every shingle has a nail tab in the corner which will help you a lot as you will know where to hammer in. Nail clip will also have to be used. They are sold together with the shingles so you won’t need to buy them separately. For this, you can use nails that are approximately 1.5 inches long.
- Continue by adding shingles
After the first shingle, you have to add other ones. They will need to be placed one next to another and so on. You will find a tab on the underside of the right shingle. It can be used to hook them together. When you do that, just slide it into place. There is basically no difference between the first and the second shingle in that regard. The main difference in installation is that you will now start attaching them to previously installed shingles instead of hooking them to the roof.
- Adjust the length of the last shingle
In most cases, the last shingle will be too long. You can fix this by cutting its side to a proper length. Simply put it in place and mark the line where you need to cut it. Remove it afterward and simply cut it along the line. This is usually done with steel cutters. Keep in mind that metal shingles are really tough so don’t try cutting it with something that is not strong enough. That can only damage the tool. We also recommend that you use gloves for this step. The edge of the shingle will be very sharp so you can easily cut yourself if you’re not careful.
- Cover the whole roof
Now that you know how shingles are installed, you can slowly cover the whole roof. No matter what you do, don’t be hasty! The roof has to last for years and years, and given that each shingle can affect another, you can easily make mistakes if you’re not too careful. There is no rush. Even if it takes several days, it is much more important that the installation is performed properly. In the end, you’re not a professional. Given that this can take some time, perhaps it would be good to ask a neighbor or a friend for some assistance.
- Installing ridge cap shingles
The last step of the process is the installation of ridge cap shingles. You can buy them at the same time as other shingles. There is nothing new regarding ridge cap shingles as the installation process is basically the same. You start from one side and secure the first shingle then slowly go forth by adding other ones. The last shingle also has to be cut to fit the roof.
With these awesome tips, you’re ready to install your first metal roof!
