Standing seam roofing tool with your own hands

Installation of a self-latching seam roofing instruction

Despite the emergence of a large variety of modern materials for roofing, many homeowners prefer options that have long been used and managed to acquire a strong reputation.

The seamed roof is made of rolled steel, galvanized steel, non-ferrous metals, as well as steel with a polymer coating. And it is so called because the connection sheets are performed by the seam method, when they are fastened to each other without nails, screws and other devices. The result is a perfectly sealed coating on the roof.

To transport sheets (paintings) use truck transport. When unloading the sheets are carried in a strictly vertical position and one by one. To lift them on the roof using a ladder, planks or boards that are installed between the ground and the roof.

Terms used by roofers.

First of all, you should familiarize yourself with the basic terms that will occur in this article and other instructions for the installation of metal roofing:

• The seam is a type of joining of two sheets of metal, in which the edge of one of the sheets is wrapped around the edge of the other. This connection is very reminiscent of the seams that are used for sewing clothes.
• The picture. Such an original name was given to metal sheets, which are already prepared for the formation of the folds. Preparation of paintings is carried out on special machines, metal sheets bend the edges at right angles.

Types of seams

In the process of installation can create a different kind of folds. There are the following types of folds:

The seam roof installation instructions. The seam roof. Technology seam roof installation instructions. Standing seam roofing. Technology Installation of seam roof: technology, instructions for the device

• Standing. After the formation of the seam, it remains at right angles to the coating.
• Standing. Such folds after clamping, tilt, pressing against the roof.

Tip! Standing seam is much more reliable than the lying seam, however, their use is not always possible. So, when forming horizontal rows on the roof, you will need to perform recumbent connections, otherwise the water will not be able to properly drain off the roof, and the coating will form puddles.

Depending on the number of folds performed during the formation of the seam, there are single and double joints. The latter, of course, are more reliable, but to make them more difficult.

Depending on the number of bends performed in the formation of the fold, there are single and double joints. The latter, of course, are more reliable, but it is more difficult to make them.

Construction types

The design of the roof provides one of two varieties of sheathing. continuous or sparse; choose which of them to prefer, in each case is decided after choosing the final coating. Features of these types are characterized by the following parameters:

Solid trim

Moisture-resistant sheet material (FSF or OSB) is laid with a gap not exceeding 1 cm. This indentation allows you to compensate for changes in the linear dimensions of the material during operation (with increasing humidity and air temperature is expanding and vice versa).

For the arrangement of continuous sheathing is preferable to choose sheet metal, and not boards. The advantage of this choice. perfectly flat surface, free from the differences that are inevitable when using boards. A solid base has some disadvantages:

• Cost. Plywood and board material (OSB) is more expensive than boards, so the construction of such a base will lead to an increase in the construction budget.
• Occurrence of condensation. Dense laying obstructs air circulation under the roof. If the ventilation gap is not provided, the roofing pie will inevitably begin to retain moisture, which will adversely affect its quality and destroy the insulation (if it is provided).
• The need for. The solid foundation is a technological necessity for shingles. For metal roofing is more logical to arrange a sparse crate, it will be more practical and economical.

Sparse purlins

Regardless of the design features of the roof, the optimal lumber for sparse construction (for most roofing) is considered

• Bar section of 5×5 or 6×6 cm.
• Board for roof trim 2-4 cm thick.
• Quality. A prerequisite. the choice of timber is not lower than grade 2. Knots and other defects on the low-grade timber can eventually cause breakage of the elements under the weight of snow. Another condition. you should buy a well-dried wood. Raw lumber will certainly begin to deform, and fasteners (nails, screws) will weaken and begin to fall out.

Step sheathing, mounted in a row, is selected taking into account the chosen finish coating, and it varies within fairly narrow limits. Such a base is suitable for laying ceramic tile, corrugated slate, metal.

Peculiarities of the construction of a roof of copper and zinc-titanium

For the manufacture of a seam roof is sometimes used and specific materials. Such materials can include zinc-titanium. Such a roof has an attractive appearance and long service life. The main disadvantage of titanium-zinc roofing is its high sensitivity to mechanical damage.

Therefore, the installation of a seam roof of titanium-zinc must be carried out very carefully. Scratches and impacts on the sheets should be avoided. A marker should be used for marking.

To work with this material must have special tools: shaped and straight scissors, bending pliers, etc.д.

The laying of the roof covering of zinc-titanium should be carried out in a warm season. At temperatures below 5 degrees Celsius the fragility of materials increases significantly.

The roof of the copper and titanium-zinc sheets looks aesthetic. It can last over 100 years. Under the roof of copper sheets must do continuous crate. In this case, the sag of the coating under its own weight is excluded.

Advantages and disadvantages

The main advantage of the coating is the minimum number of joints at its arrangement. Even the high complexity and specificity of the work do not often stop people who prefer this product, because its advantages are really significant:

• According to manufacturers, the service life of the seam roof is 100 years.
• On sale there is a wide range of products of different sizes and colors.
• Low weight at a sufficiently high strength of metal.
• Due to the smooth surface of the metal coating, rainfall on the roof almost does not hold. Therefore, the rafter system is not subjected to particular loads.
• Ability to use on roofs of complex shape.

But despite all the advantages, the seam roofs have some disadvantages. These may include:

• Significant noise during rainfall.
• In the case of failure of the coating will have to spend a lot of effort and time on its repair.
• Difficulty of installation. If you do not possess sufficient knowledge and certain skills in the field of construction, it is advisable to entrust the installation of a seam roofing specialists.
• The need to install lightning protection. The fact is that metal tends to accumulate an electric charge, and this increases the likelihood of lightning hitting the house.

Installation

The main terms for the seam roof

• Klemmer. an element for fastening. It is fixed to the base of the roof. This fastener follows the shape of the rebate workpiece. Movable brace is needed to protect the metal from expansion due to changes in temperature parameters.
• Falc is a seam formed by joining and fixing two sheets of metal. Such joints are, in fact, stiffeners to maintain the shape of the entire roof mat. The seam provides a tight connection between the plates. No additional use of sealant.

Material

Blanks for the seam roof are made of galvanized steel and non-ferrous metals. Consider other materials:

• Steel. The most used metal. The steel seam roofing can be galvanized, non-galvanized or coated. Of the advantages. Resistant to corrosion, affordability and service life of 60 years. There are disadvantages. Steel tarnishes over the years without additional coating. Therefore, the device of a seam roof of this material involves the use of colorful multilayer coating. When shipping steel cards should always check that the special protective film is not damaged. This is important so the paintings won’t get scratched or damaged during shipping.
• Copper. Installation of a copper roof seam. expensive because of the high cost of the material. But it is the most beautiful roof, which will shine beautifully in the sun. Another advantage of such a coating is that moss and other plant formations do not take root on it. But there are some clear disadvantages. Copper is a so called soft metal and must be handled with care. Over time, the copper roof is covered with a layer of oxides. Patina ages the roof and changes its color to dark brown. Appreciate the copper seam roof for flexibility. It is easy to make real architectural masterpieces. With this advantage, copper roofing is widely used in cottage communities built on special projects.
• Zinc. Zinc sheets for seamed roofs are additionally covered with a layer for protection. zinc carbonate. This coating somewhat changes color and becomes silver-gray.The service life of a zinc roof. about 50 years, which is relatively small.
• Aluminum. Currently, a new trend in cottage construction. aluminum roofing. It is resistant to impact, damage and corrosion. Serves more than 100 years. The coating has a unique silver sheen. Plasticity and lightness. these are the advantages appreciated by craftsmen when making complex assemblies and elements of the facade. When making a roof of copper materials there is no need to use special machines or tools, there is no need to spend extra money and time. When comparing and choosing the material for the roof, aluminum turns out to be of higher quality and lasts longer than the popular steel, and is not inferior to expensive copper. To correctly install the seam roof, and it served for a long time, you should know all the subtleties of work. For reliability you can use the services of the construction company. Specialists will be able to quality assemble a roof for you, while respecting all norms and standards. The cost of installation of a seamed roof per square meter will be within reasonable limits.

Set of tools

The seam roofing for a private house or cottage is not difficult, so the work on the installation can be managed independently, but it is necessary to stock up on a minimum set of tools.

Devices needed to connect the sheets directly on the horizontal surface of the roof and for the device nodes adjacency in places where the output on the roof of chimneys, vents, ridges and other protruding structures.

The following set of tools is required:

• mallet;
• metal scissors;
• Hammer with a handle for rebates;
• roofing mandrel, to bend the metal;
• tongs;
• frame;
• Pliers.

Start

It is important to prepare the floor well. In the new construction of the crate for a seamed roof must be reliable.

When reconstructing used purlins should be updated (partially replace the boards of purlins) or completely replace the crossbar and chipboard sheets. Initial steps:

• Assemble a purlin of beams with a section of 50-100 mm;
• fasten the timber safely with nails and self-tapping screws;
• Assemble a row of joists across the first;
• lay on top of the timber purlins moisture-resistant chipboard;
• Fix the vapour barrier.

Basic actions

After the seamed roof pie is made, you can proceed to laying the material. Before this, the sheets should be adjusted to the shape you want.

• Remove the protective film from the boards;
• Cut the boards to the slope width;
• If necessary, to bend a vertical rib of each plate not more than 25 mm;
• cut a hole on the vertical rib for attaching to the batten;
• Make holes with an electric drill;
• bend the roofing sheet for installation in the eave knot;
• Fix the sheet at one end to the base of the roof with flat roofing screws to the wind batten;
• Fix the other edge of the leaf to the crate with flat-head screws;
• Assemble all the sheets of the roof, snapping them into place;
• trim the lock, cut and fit to the desired shape;
• install the windbreaks;
• mount the ridge.

It is important to follow the technology to bend the seam.Connect the folds with each other can be using a hammer and wooden bars. An electromechanical folding machine can greatly speed up the process.

The cost of

Purchase materials for installation of the roof can be purchased at the following indicative prices:

• Galvanized sheet per m2 can be bought for 400-500, the life of such material. up to 15 years. This is not the most modern, but the most inexpensive and still well-bought raw materials for roofing.
• Coated sheet will cost more. from 400 per 1 m2. Its performance characteristics are much higher and it serves longer. For example, there is pural. Its cost. 890 per square meter in a roll. Rolling up and cutting of the sheet is paid extra. Use of such a sheet can be without repair by times longer than galvanized sheet. Of all the polymer coatings, pural is the most popular, well-purchased coating because of its unique properties combined with premium steel.
• Sheets of aluminum can serve up to 40 and even more than 50 years. For such a material should spend 1500-1700 per square meter.
• Durable and expensive coating is zinc and titanium. These sheets can last up to a hundred years and cost roughly from 3000 per square meter.
• It is more practical to buy copper for roofing. It’s in the same price range, but the lifetime. Up to 150 years, and always looks very decent. These are given for roll and sheet materials. Metal for roofing can be shipped ready-made billets with bent edges.

The price of a seam roof is highly dependent on the manufacturer.

For Russian steel with protective polymer coating, you must pay from 500 to 800, and the sheets of imported production. twice as expensive.

Professionals often try to use expensive and durable materials for roofing, they fully pay for themselves and are worth it. They serve without repair for a very long time, and the material does not deteriorate from corrosion.

Roofs of sheet steel and galvanized quickly enough to age and rot. Increase their life can be, but it will be more money. Periodically need to cover the roof oil paint.

Self-assembly

To prepare any of the above connections will require a special mechanism. the so-called machine for rolling up the fold “. We do not recommend even trying to replace it with any homemade device (or other improvised means), the use of which may violate the technology of formation of the seam and, consequently, reduce the quality and reliability of the resulting joints.

Machine for rolling seams

If you can not (or do not want) to buy a machine for rolling seams, you can use a roofing kit with pre-formed edges, providing a self-locking seam. The latter consists of the so-called “locking tooth”, which, when imposing one metal strip on another is easily captured by the hook-shaped profile available on it. To get a secure connection you just have to click the lock, which usually takes very little time.

Self-locking seam

Using the finished (molded) roofing material greatly simplifies the installation of coverage, and significantly reduces the time of construction work. For the arrangement of the seam roofing in addition to the machine need the following tool kit:

Installation Features

Fastening of the roof

In the arrangement of the seam roof is necessary to consider the following features of the organization of installation work:

• Regardless of the chosen method of connecting the sheet metal work is carried out by means of their fixation on the crate by means of special brackets, whose feature is their absolute invisibility.
• Each panel to be installed must face the direction of the next panel with its bottom lock.

Fixed brace

In the construction industry 2 types of klyamernyh mounts: movable and fixed. For plates longer than 8 metres the movable version is used, whereas the fixed version is used for relatively short plates. These fasteners also include a standard self-drilling screw complete with press washer.

Movable brackets

Installation of roof decking is conducted from the bottom up while maintaining the fixed distance between the longitudinal joints. It does not matter which side of the roof installation start, the main thing to pay attention. this is the correct orientation of the bottom lock.

Self-assembly

To prepare any of the above-mentioned joints you will need a special mechanism. the so-called folding machine”. We do not recommend even trying to replace it with any homemade device (or other improvised means), the use of which may violate the technology of the seam forming and, consequently, reduce the quality and reliability of joints formed.

Why do I need a folding machine. the principle of action, popular models and a scheme of homemade machine

Modern folding machine tool is used to create blanks for different types of folds. I will tell step by step about the principle of operation, types and popular models of machines, as well as explain how to make a folding machine with your own hands.

The seam roof is considered one of the most durable.

Production technology

Falceprokatny machine is indispensable for both the arrangement of the seam roofing itself, and for the manufacture of auxiliary roofing fittings. This includes elements of the gutter system, frontal and end eaves of the roof, and with its help make ventilation boxes of galvanized steel.

Types of folds

Seam joint is a twist between two adjacent sheets of metal, and to arrange this curl, you need to bend the fold at the edge of the sheet, that’s just for bending this fold and need a folding machine.

There are 2 folds. a single and double fold, plus the folds can be a standing and lying.

The level of tightness depends on the choice of connection.

• Single fold is the basis, here is just a sheet of bending at 90 º, and the second sheet is made a kind of hook and after connecting the hook crimped;
• Double fold can be called an analogue of the single fold, but the twist is done in two turns. To so wrap the metal size of the hook in the workpiece should be less, on average about 5-7 mm, and the height of the workpiece is done on the contrary, more.

As for the recumbent connection options, they are exactly the same as the standing seam, only turned sideways.

Now quite often found L-shaped roof seams, any practical advantage of such a connection is not, it is not better and not worse than a double gusset, but many believe that so the roof looks much more impressive.

Especially good L-shaped seam looks on rounded radii.

In the selection of equipment, please note that there are machines for the arrangement of the lying seam, standing seam and the universal units, which can be rebuilt as necessary for any type of curvature.

General information about the machines

The main advantage of the seam roof is that the coverage is monolithic, without any mounting or connecting holes. But the roofing metal itself is quite thin and make a blank in the manufacture, and then transport them to the site inconvenient, and often unrealistic.

A small folding machine changes the situation radically. With such equipment, you can make blanks directly on the site, moreover, there are models that can be installed directly on the roof.

There is another important nuance: for bending the edge of the sheets needed folding machine, and to make a double fold and press the connection to bring it to the final result, is used fold-osadochny machine.

The folding machine at times reduces the time of arrangement of the roof.

Often the thickness of metal for roofing work varies in the region of 0.5-1 mm, with a maximum of 1.2 mm. But a good machine for the seam roof is calculated to work with metal from 0.3 to 1.5 mm.

This equipment is closer to the professional, and it can do not only the roof paintings, but also to bend blanks for all kinds of gutters or vents, plus do valley gutters and ridge caps.

By the way, billet for a seam roof (strip roofing metal with bent folds) among professionals is called “Painting”.

The principle of operation of the unit is simple: any folding machine has a number of crimped figured rollers, which actually bend the edge of the sheet. Crimped rollers are installed in pairs on crimped rollers.

Folding machine with a manual drive is suitable for amateur use.

The number of these crimping shafts may vary, but no matter how many there are, they are driven by a gearbox, and the gearbox itself is rotated by an electric motor. There is, of course, equipment with a manual drive, but the performance there is very low and such units are rare.

Falceprolling machine with their own hands

Work related to construction of buildings and installation of the roof are using modern equipment.

To do this, machines are used to create seams. This can be a makeshift machine, made by hand, or factory analog, such as folding machine CFP 700.

What do you need a manual folding machine?

Sheet or roll metal is used to create a seam roof. The edges of such roofs are connected by a special seam. the seam. Forming a watertight seam seam is possible with a device such as a folding machine lc 12r or CFP 700.

The main purpose of such a machine is to provide mechanical bending of sheet metal for roofing to create seams. Rent a folding machine relevant in the event that the amount of work carried out will not be large.

In the application of the device brand SFP 700 all types of roofing can be done in the form of rolls, not individually laid sheets. The SFP 700 model allows the operator to significantly reduce the time of work several times, increase productivity and minimize the number of cross seams in the roof.

Rent a folding machine allows you to create a double or even triple lock on the joints of the roof, and the finished panel will be equipped with rolled ribs. These elements will greatly increase the strength of the entire structure and improve the appearance of the roof.

The machine is needed to form a watertight rebate seam on the sheet metal

Rental folding machine is also relevant in cases where you need to form a roofing pattern of rectangular, wedge or trapezoidal shape. In addition, the manual machine SFP 700 can be used to create:

• roofs;
• air ducts;
• chimneys;
• eaves;
• slopes;
• drainpipe systems;
• decorative roofing curves.

Manual machine SFP 700 is intended for the production of various profiles on the edges of blanks or sheets of galvanized steel. Also can be used materials with polymer or paint coating.

The only significant disadvantage of the presented machines is a high cost and large size of some models. However, a machine like SFP 700 and its analogues are different:

• adaptability to the conditions of modern construction sites;
• No damage to the material coating;
• the high quality of the manufactured panels;
• The ability to produce rectilinear panels;
• A stepwise resetting of the desired width of the workpiece.

Device features

The SFP 700 manual machine has such modules as a forming machine, base and electric drive. The frame is represented as a welded metal structure, on which the shafts are placed.

Steel rollers pull the metal strip along the machine

They ensure the formation of an even welding seam. A forming machine pulls the metal strip along the machine. Thus, the ribs and stiffeners of the double fold, necessary for the interlock of the elements of the roof.

If you need to change the width of the metal strip, the device manually readjusts to the new size. The electric drive of the SFP 700 consists of an electric motor, a chain-type transmission and a worm-gear reducer. Home-made machine can be further equipped with a roller unwinder.

It is designed for mounting, uncoiling and further feed of metal in coils. The unit can also be equipped with a device that connects the sheets into a continuous roofing sheet. The moving part of the machine includes two movable rods connected by a clamping bracket.

The sliding device is mounted with the help of springs at the top of the bed. It helps to insert a sheet of metal and remove it after the edge is bent. The profiling mechanism is placed on a tubular steel frame. The rollers of this element are made using steel with a special finish.

It protects the elements from corrosion. Homemade machine can be equipped with both manual and automatic crimping device. In addition, the homemade machine for easy transportation must be equipped with four wheels. menu

Overview of common factory models

Mobile device for roof bending CFP-700 can produce panels equipped with a double standing seam. The machine can work with all kinds of roofing metal, including steel, copper, zinc or polymer coatings.

It is equipped with six working rollers and has an optimized configuration of profiling rollers. They ensure the high quality of the manufactured coating. When working on a construction site the machine can simultaneously serve up to two roofing teams. Benefits include:

• low weight and dimensions of the device;
• simple and reliable design;
• the possibility of stepped adjustment of the width of future panels from 200 to 700 mm;
• It is possible to make different types of panels. straight, trapezoidal, one-sided;
• the possibility of installing a mechanical motor (in the absence of mains electricity).

Folding machine IC 12R, as its counterpart manual folding machine lc 12r (FPS) also produce preparation of the edges of pre-roll roofing sheets. Model with the designation “R” performs nakatku 5 varieties of folds, including a standing radius.

As a folding machine lc 12dr, the device marked “DR” is also capable of rolling up to 5 different types of folds. An additional advantage of the device is that it can form a connecting strip.

Mobile roofing machine SFP-700 produces panels for double standing seam roof. The machine works with all types of roofing metal (steel, t.ч. coated, copper. in t.ч. patinated, aluminum, aluzinc, zinc-titanium) in rolls and sheets. Six working stands and optimized configuration of profiling rollers ensure high quality of produced roofing panels. When working at the construction site of roofing machine SFP-700 serves two teams of roofers at the same time.

Sfp 700 roofing machine is needed for production of seam roofing. The production process is based on the use of modern rolling technology. Avoiding unnecessary horizontal joints, you can make roofing patterns along the entire length of the slope. Of course, roofing iron costs significantly less than sheet metal. Lifting a roll on the roof is extremely convenient. Production speed, if compared with the manual method, is several times faster.

A couple of big orders and the automatic equipment will pay for itself right away.

Be sure to pay attention to the benefits of the sfp 700 roofing machine:

You no longer need to reset the rollers manually. The width of the material to be processed is infinitely adjustable by turning the knob. The machine is very easy to adjust to the width of the roll.

Good pattern rolling. Seven pairs of rolling rollers ensure the absence of waves.

In order to make the rolling of the upper fold used unique compound rollers. Each of the rollers is divided into two independent parts, and they are fixed on one axis. This scheme allows to avoid scratches on the surface to be processed. This is important if you are working with really expensive materials or with coated paintings.
