How to Install Aluminium Roofing Sheets


The following guide explains the basic steps to follow when installing aluminium roofing sheets. It also covers the use of self-drilling TEK screws, Lapping tape, and Reciprocating nibblers. You should use an experienced professional for this task if you are not confident in your DIY skills. The steps mentioned in this article will help you to avoid any errors and ensure the quality of your finished project.

How to Install Aluminium Roofing Sheets

Self-drilling TEK screws

Self-drilling TEK stainless steel screws are the perfect choice for mounting aluminium roofing sheets, especially for those who do not have the time to drill holes in the material. These screws are made of rust-free, anti-corrosive materials and are therefore more durable than their metal counterparts. Another benefit of self-drilling screws is their increased efficiency. By reducing preparation time, these screws can help you to increase profits and revenue.

While TEK screws can be used in a variety of applications, their screw point capacity should be higher than the thickness of the material to be drilled. If not, this could cause the drilling tip to snap. Light sheet metal is also more suitable for TEK screws and power drills with adjustable clutch settings. Impact drills can cause metal dimpling and oil canning deformations. Also, do not overtighten the Tek screw and the washer. In order to achieve a good seal, compress the washer to fill out uneven surfaces.

The benefits of using self-drilling TEK screws are numerous. These self-drilling screws are more efficient, save time, and make the installation process easier. Instead of hiring a drilling machine operator, you can simply insert the self-drilling screws in the holes and secure the roof. Self-drilling TEK screws are ideal for light-gauge metal assemblies and metal buildings. Self-drilling TEK screws are available in a range of sizes to suit your needs.

Self-drilling TEK bolts are an excellent choice for mounting aluminium roofing sheets. They do not require pre-drilling holes and have a drilling point on the end of the thread. This enables them to attach to the material easily and quickly. Traditional self-drilling screws need a pilot hole before they can work, but with Tek bolts, the self-drilling TEK screw will not require it.

Lapping tape

Using mastic lapping tape between sheets is an effective way to create a robust weather resistant joint. Stitching screws should be placed at 600mm intervals along the side laps to reinforce the bond created by the lapping tape. To weatherproof the roof, a minimum of 250mm of sheet over sheet overlap must be maintained. A z or c purlin or a similar structural element must be used to support the end laps. The gaps between the sheeting and ridge flashing must be sealed, if necessary.

Suntuf and Greca sheets are overlapped one and a half corrugations and fixed every third crest of the intermediate purlins. PSP DIY fixings need 10mm holes, which are usually pre-drilled with the right size. Using PSP SupaDrive Multi will pre-drill these holes for you and allow you to install the sheets in one go. When finishing, a rubber washer should be used to seal the edges and prevent leaking.

Lay the first few sheets without fully fixing them down, making sure they overlap perfectly. Then, secure the remaining fixings with a sealant tape. Ensure that the first row of sheets extends over the bottom of the roof, allowing rainwater to drain properly. If you are having difficulty installing the sheets, the supplier should send you a guide. You can also purchase the lapping tape on Amazon.

Lapping tape is a versatile and affordable method for installing aluminium roofing sheets. It can be purchased at any hardware store or online. It is the ideal method for roofers who want to install the sheet quickly and efficiently. Butyl tape compresses out two inches on each side, creating a tight seal. However, it is only secondary protection. Unlike a standard caulk gun, butyl tape does not need to be applied to a metal roof without a sealant.

Reciprocating nibblers

Reciprocating nibblers for aluminum roofing sheets are designed to punch small holes in the metal profile while the metal profile remains suspended. The working head of the nibbler is inserted into a hole drilled beforehand and the punches the metal. A push on the handle moves the working part of the nibbler into the cut progressively. A good example is when a cutout needs to be made in the centre of the sheet.

Reciprocating nibblers are excellent tools for cutting corrugated metal wall panels. They cut through metal like butter and usually cost several hundred dollars. However, if you are planning on cutting corrugated metal panels, then this is an investment that will pay off in the long run. A nibbler comes with a punch and die that will cut the metal sheet into half-moon-shaped pieces. These nibblers are not perfect. In fact, you must be careful and practice safety before using them.

Reciprocating nibblers for installation of aluminium roofing sheets are a useful tool for cutting corrugated sheets. The nibbler’s elongated die assembly juts out at an angle of 90 degrees from the motor housing, allowing it to ride peaks and troughs without jamming. Another great feature is its swivel capability. Swivel-type nibblers can be used to cut sideways as well.

While an electric nibbler can be used to cut corrugated metal roofing, it is far from ideal for this purpose. It is too expensive to be used by amateurs and it is difficult to use in a professional setting. If you are not comfortable using a nibbler, then consider purchasing a pair of tin snips instead. They are easier to control and produce a clean cut.

Slip sheet

If you’re installing an aluminium sheeting system in your home or building, you may be wondering how to install aluminium slip sheet. Slip sheets are protective coverings for metal sheeting that’s typically placed under felt. This slip sheeting is available in rolls and should be stored at least four inches off the ground and covered with a weatherproof covering. If you’re installing a new slip sheet, it’s important to remember that local building codes may require a fire-retardant material.

To install a self-adhering sheet underlayment, make sure that the sheet is wrinkle-free. You may also need to use primer if you’re installing the underlayment in colder temperatures. Lay the sheet in a shingle fashion, with side edges and end laps at six inches and three-1/2 inches, and cover within 14 days. If you’re applying the slip sheet directly on a subfloor, you’ll need to ensure that you’re working with a self-adhesive surface to avoid any possible adhesion problems.

After you have installed the slip sheet over the plywood, you should measure the roof area and cut the sheet to fit. If your roofing is made of aluminum, you’ll want to use a high-quality screw to hold it in place. Alternatively, you can apply the slip sheet to the top layer of the metal roof. A high-quality slip sheet will protect the metal from heat and sun exposure, while also allowing drainage to run down the side of the roof.

Adding a barge

If you want to add aesthetic value to your roof, then adding a barge is an ideal solution. Barges, also known as verges or barge boards, fit onto the roof pitch and provide added strength and protection. The barge should be placed 200mm from the edge of the roof verge, ensuring there is a minimum overlap. The following steps will help you install a barge.

First, measure the length of the ramp and calculate the number of whole slats needed to cover the roof. Cut the slats to the correct length and begin installation from the bottom of the ramp. The vertical part of the box barge cover should cover the battens at the ends. Next, place the aluminium roofing sheet in the topmost row. Repeat the installation process until you reach the top ridge.
