How to Install Standing Seam Metal Roofing

To get the most accurate results, you will need to provide the exact building measurements and roof pitch.

Very Important Note: Before you order your metal roofing panels, you will need to get on the roof and physically measure its run, to the exact number of feet and inches. REMEMBER that the calculator provides only an APPROXIMATE length for your roof panels. If you do not measure the exact length of your roof run, your panels may come out too short or too long. If your panels are too short, they may be unusable. We are not responsible for the accuracy of any measurements on your part.

When measuring your metal roofing panels, always measure from the eave all the way up to the ridge line, and add at least 2 inches for drip edge and return lock.

Measuring your roof you will need to use a tape measure to get the width and the length of your roof. You will also need to calculate your roof pitch, and properly identify your roof type. Use the following guides, which will help you to accurately measure your roof:

• Roof measuring guide learn how contractors measure and estimate roofs.
• Roof Pitch guide learn how to measure and calculate roof pitch. Roof Pitch multiplier table is provided at the end of this guide.
• Roof Types learn how to identify your roof type, and discover the difference between Gable, Hip, Mansard, Gambrel and Shed roofs.

## Why Is Standing Seam Metal Roof So Expensive

Standing seam metal roof is the foremost choice for metal roofing, even though it is the most expensive. In comparison to corrugated metal panel roofing, standing seam metal roof can be as much a thirty percent more. When we consider the durability, energy-efficiency, longevity, and style, it is an unbeatable value.

The standing seam metal roof metal type is usually G-90 Galvanized Steel. It is also available in aluminum, copper, Galvalume G-90 Steel, and Zinc, each are factory coated. Steel coating quality and thickness or gauge can affect the pricing.

## Tear Off Your Old Roof

Before your new metal roof can be installed, your old roofing materials need to be torn off to get to a clean deck. What this means is that your roofing contractor will go section by section removing old roofing materials and tearing off your old shingles from the roofs decking.

Starting on the end furthest away from the dump trailer, theyll start using special tear-off forks to tear-off your old roof by sections. While one crew is going from section to section tearing off, another crew is making sure the torn off materials end up in the dump trailer or the tarped landing zone in your yard.

## More Options For Standing Seam Systems

#### Striations or Stiffening Ribs

Striations, also called stiffening ribs or rib rollers, are the patterns rollformed into a metal roofing panel between the seams. These can be used to assist with the installation of a metal roof, to help reduce the visibility of oil canning, or just for curb appeal. In fact, we recommend using striations in standing seam panels, some available options include:

• Flat No indents between the seams
• Striated Small consistent indentation lines in the panel
• Ribbed Shapes or indentations between the seams
• Pencil Circular panel indents
• V-Ribs V shaped panel indents
• Bead Longer, rectangular panel indents
• Clip relief A stiffening rib adjacent to the seam that allows the space for a clip underneath
• #### Thicknesses

The metal coil that is rollformed into panels comes in many different thicknesses however, standing seam panels are typically somewhere between 22 and 26 gauge, with the most common Galvalume® thickness being 24 gauge and aluminum between .032 and .040 inches.

## Larger Roofs Can Lead To Larger Problems

The next picture shows that those problems can be multiplied when the roof is larger. Not only was the transition flashing not done, but the outcome was far worse due to the size of the roof. You can see the oil canning due to the stress on the panels and the inability of the panels to move freely because they were not terminated at the transition and properly flashed. Just plain UGLY! Definitely not the right stuff. We do not know which company was responsible for this roof.

## Lock The Ridge Capping Into The Z Bar

Once the Z bars are installed, your standing seam metal roof will be ready to lock in into the ridge capping or transition metal. Ridge capping is the trim installed at the peak where the two slopes of a roof meet. On your standing seam metal roof, it will be the same type and color as your metal panels.

If your panels are coming from a low slope roof to a steeper slope, youll need transition metal instead of ridge capping. The transition metal should come down the roof and out 6 inches to ensure there’s a straight plane all the way across and then lock onto the Z bar.

Once your ridge capping or transition metal is installed, your metal panels will be completely locked in, and youll have your new standing seam metal roof.

## Standing Seam Metal Roof Installation Process

Step 1 Installing the drip edge

Installation of the drip edge is usually a rather simple process, but for a novice roofer it can be a challenge. Ill take a step back to the first part of this guide when prepping your deck, make sure that the old drip edge is completely removed, and all rotten wood is replaced.

There are several opinions as to whether install drip edge under or over the underlayment. In theory if you install drip edge over the underlayment, then run-off rainwater may get underneath it. In reality, metal drip edge gets installed so tightly, that water just rolls over it. Therefore, I always install underlayment first, and then go over with the drip edge.

Advantages of installing drip edge after the roofing underlayment has been installed, are as follows: You do not waste any precious time during the installation of the drip edge when and if your roof is open and it rains, you may not have enough time to cover it, thats where having water and vapor barrier in place really comes handy. Second reason is the safety.

When I install underlayment, first I can trim the edges as I please, in case that a hang off portion of the roof is too lengthy. If your drip edge is already in place, and underlayment hangs off it, trimming it may be rather dangerous, while sitting on the edge of the roof.

If rainwater does get onto the underlayment after a metal roof has been installed, then you have bigger problems to worry about!

## Advantages Of Standing Seam Metal Roofs

Longevity, when compared to traditional roofing materials, is the biggest advantage of a metal roof. Standing seam metal roofs last 50 years or more which results in much longer warranties on the metal roofing panels. Standing seam metal roofs can handle the toughest extremes in weather and are less likely to create ice dams. This means they are especially helpful in climates that receive a lot of snow. Standing seam metal roofs are also incredibly energy efficient making them a smart choice for the environmentally savvy. They are excellent at reflecting and dissipating the sunÃ¢s rays. They also come in a wide array of materials and colors to match the aesthetic of your home. In addition, they offer a sleek, consistent, and modern look to your home.

## Advantages Of Exposed Fastener Metal Roofing

LESS EXPENSIVE One of the most significant benefits to choosing exposed fastener metal roofing is that its less expensive, especially when compared to standing seam systems. There are many reasons for the lower price, including:

• Wider panels
• Fewer metal panels need to be purchased.
• Less labor is needed because the wider panels cover the roof faster.
• Thinner gauge panels
• Lower quality paint systems
• Polyesters and silicone-modified polyester paint systems are popular choices for exposed fastener because theyre less expensive than the polyvinylidene fluoride paints typically used on standing seam systems.
• Less accessories purchase
• Exposed fastener systems are directly fastened down to the structure through the metal, so theres not a necessity to buy any kinds of clips. This can save on costs for the buyer.
• Exposed fastener systems usually use less accessories and different flashing products, like foam closures, to install the roof system. Again, this cuts down on costs and speeds up the installation.
• NO SEAMING REQUIRED Exposed fastener systems do not require hand or mechanical seaming the two panels. Most systems use a lap seam where the edges of each panel overlap the one adjacent to it and are then fastened down together at the same time. This is often why exposed fastener metal roofing tends to be considered the less labor-intensive option when compared to standing seam metal roofing.

## Whats The Difference Between Each Type Of Standing Seam Panel

Each Standing Seam panel is installed and secured to the roofs substrate differently. Their names each reflect the different ways they come together.

Mechanical Lock panels are mechanically fastened to one another, meaning a special tool called a seamer is needed to lock them together. These panels use a clipped system that fastens them to the substrate. Then, you use an electric or hand seamer to press them together mechanically, which bends each panel over one another and creates a lip. Mechanical Lock panels require a more advanced installation.

Mechanical Lock

Tru Snap metal panels have two identical female legs and snap together. With Tru Snap, the male leg is clipped, and that clip is fastened directly to the decking. These panels require more parts and pieces, making installation a bit more difficult. However, Tru Snap can be run with longer panels due to the clipped system it uses, which allows the panels to move more freely through expansion and contraction.

Tru Snap

Nail Strip metal panels also have two identical female legs. The big difference is that with Nail Strip panels, the male leg has a perforated nail flange used to fasten the panel directly to the decking. Nail Strip is a bit easier and more straightforward when it comes to installation, however it is limited by how long you can run the panels since theyre screwed directly to the decking.

## Standing Seam Metal Roof Installation: Clip Attachment

When youre installing a standing seam roof, correctly attaching the clips is essential to having a successful roof installation. Western States Metal Roofing has the expertise to help with this.

In this article, we will tell you everything you need to know to prepare your standing seam panels for installation including:

• Bending and notching standing seam at eave end
• Preparing and installing the first panel
• Clip spacing and installation
• Preparing and installing the last panel

Prior to installation, you want to make sure that your roof is clean of any dust or debris. Also, inspect the roof for any protrusions such as nails or other objects.

Before you begin this part, you need to know that standing seam panels have a different profile on each side – a male side and female side. The male side is the left side of the panel which allows clips to be attached and fastened. The right side is the female leg which clips onto the adjacent male panel.

## How Long A Standing Seam Roof Will Last

The lifespan of a standing seam metal roof is how many years youll get out of it. The amount of years youll get out of your standing seam roof comes down to its painted finish.

All of the major steel panel manufacturers use a patented process to apply a painted finish called Kynar 500 to standing seam metal panels. This painted finish protects your metal panels from the elements and keeps the color you choose from fading.

Your standing seam metal roof comes with a 30-year paint warranty on the Kynar 500 finish. Even though the paint has a 30-year warranty, it doesnt mean its going to disappear after 30 years.

As long as its properly installed and your attic is adequately ventilated, theres no reason you shouldnt get at least 30 years out of your standing seam metal roof. Under the ideal conditions, a standing seam metal roof could last for 50 years.

## What Is Standing Seam Metal Roofing

Standing seam metal roofing is defined as a concealed fastener metal panel system that features vertical legs and a broad, flat area between the two legs. Its also described as having raised seams, or vertical legs, that rise above the level of the panels flat area. Standing seam systems can be used for either metal roofing, which is the most common, or metal walls.
