Roof Jacks Degrees And Safety Precautions

Roof Jacks: Degrees and Safety

Most roof jacks depend on angles. Since there are various angles of roofs, it is important to use a roofing jack according to the angle, or pitch, of the roof. Standard roofs are around 3/12 to 6/12 pitches. Of course, there are old homes which have an outstanding pitch of around 8/12 and above. Again, it is important to know the pitch of our roof in order to know which type of roofing jack to use. Basically, these jacks have various degrees.

The 2 X 6” By 45 Degree Roof Jack Bracket

The standard type of roofing jack which is sold today is the 46 degree jack. We can use this type of roofing jack in 3/12 or 6/12 pitches. Usually, this type of jack has a bracket support made out of thick steel. The support enables the jack to hold the weight of the user while the same time it allows adjustment. In case the user will remove the jacks, there are some adjustable bracket holes for the bracket support steel. There are also four welds per bracket, which is used to improve the balance of the roofing bracket.

The 2 X 6” X 60 Degree Roof Jack

Another type of roof jack is the 2 x 6” x 60 degree type. This is designed for very low slopes of up to 6/12 pitch. Like the 2 x 6” by 45 degree, this type of jack also has a bracket support made up of 1/4 “steel. Usually, most of the sheets are thicker so that the jack will always be stable. This type of jack also has a 4” place bracket. In order to fully secure the bracket, most carpenters need to use three 16 penny or some 3” common type round shank nails.

The Interchangeable Jack

For roofs which are 8/12 in pitch, the appropriate jack to use is the interchangeable, or adjustable, jack. This type of jack has a degree adjustor so that users will be able to pick the angle that they need. Once the angle is picked, there is also a sheet of thick metal in order to hold the roofing jack in place. More about Roof jacks vent and roof vents

Safety Is Important

*We are not responsible for your actions. Hire roofing contractors and professionals only.

In order for the roofing jacks to be structurally sound, it should not be dropped from the roof. Never drop it from a high angle since it can actually damage the metal sheet. Once the sheet is damaged, it will be impossible to adjust the roofing jack. Inspect the wooden plank which you will be using. If the plank is not structurally sound or if it is very short then it is better to use another one. Also, it is important to always inspect the jack before and after using it. The roofing jack’s support brackets should still be structurally sound and the metal sheet should be free from any rusting. Once the metal starts to rust, cleaning it with a lubricating agent is advised. Misuse of the equipment can actually result to injury and damage. The roof jack that you will acquire should also be approved by fall arrest system and it should be protected by law.

How to Use Roof Jacks With Ease

The main purpose of roofing jacks is specifically for safety. The shingles are actually laid starting at the very low edges up to the roof up to the scaffolding and the ladder. Once we have finished the first areas of the roof we actually move upward and once it the slope it is crucial to move to an area where we can actually step on something. The problem is that we often need to move without removing the nails since we might end up having nail holes on the roof. This is actually where the jacks will be used.

The First Step In Using Roofing Jacks

In order to use the jacks, we first need to lower the courses of the roof from the ladder. Once we can comfortably reach the roof then we apply the jacks. Generally, we often use five or four courses before applying the jacks. Upon laying the lower courses, we need to set the first jack in the place which is near the edge of our roof. With the span of the top metal positioned on the row found in the diagonal slots, we need to entirely move the top position of the jack to the top shingle. This is the area where the shingle will be completely covered by an overlapping course.

The Next Step Is Applying Nails

The next step in applying the jacks is to put a nail on the top of the slot. We will need a hammer in order to safely hold the nails in place. Hammer the top of the nail until it is far enough flat on the jack. Remember to not pound it harder than the specific area. Use another jack in about four feet over from the previous one and then another from the next four feet. Do this until they are safely positioned across the shingles of the roof.

Applying The Boards Of The Roofing Jacks

Once secured, the next step is to lay a 2×10 piece of board onto the 2 jacks. Use the board as the footing while we are applying the next several courses on the roof. Move the board to the next pair of jacks until they are completed. During this time, we should be able to safely move around without the risk of falling. If it becomes uncomfortable then we need to take the board off the jacks and then use a hammer to pop each jacks upward into an angle through hitting it on the bottom. The nails should still be in place and we will be able to move easily without losing balance.

After The Project

Once we are done, the next step is to lift each of the shingles where the nails are found underneath. We need to give each of the nails a hit with the hammer in order to sink them perfectly on the level of the roof. We also need to move the jacks to one of the top half or on the top row of the shingles. Good roof insulation will make your house warm at winters and home will be energy efficient. This is how we will be using the roofing jacks.
