They are backed with our equally long certified metal roofing contractors warranty.

They are cost effective as they can be installed over some old systems to save on tear off costs incurred while bring it to the current standard. Metal systems provide a protective fixture that does not split, gather mold or warp unlike asphalt shingles. They are highly durable and are able to withstand extreme weather conditions with very little storm damage from heavy snow, hurricane force winds, wind driven rains, hail and extreme heat. Our metal roofing systems are usually made of galvalume, steel, copper or aluminum. Formed into standing seam, shingles or panels the durability makes it an ideal roofing material. With the highest viability in the commercial sector. Manufacturers of metal systems reap huge profits, as the demand is high for these products.

Our metals come in a variety of standards, shape, sizes, and colors are endless. Their attributes are impressive. They are long lasting and durable requiring little or no maintenance. Adding style and appeal to your property as they also offer extra protection through their fire resistant properties. Metal roof systems set the standard for energy efficient and have been known to reduce energy bills by up to 20%.

Our metal systems are available in flat sheet, standing-seam, Bermuda panels and shingles.

Our standing seam roofs are more common in the commercial roofing industry more now than ever before. On residential custom homes, these products provide the most durable system as you can get. The durability and quality of our roofs comes from quality installation and is enhanced by the gauge of the metal roof system.

Our metal systems are generally less expensive compared to most other metal systems installed by a Phoenix roofing contractor, they are lighter in weight and are available in numerous appealing colors and designs. They retain their aesthetic appeal for a very long time. In addition, due their lightweight construction they exert very little strain on the structure. Their inherent rust resistance is also a big advantage. Available in countless shades of weathered copper, real copper, green, gray etc. these products complement the decor and architectural style of any building structure. Modern technology has imparted reflective and heat resistant qualities to metal products.

Stainless steel is one of the costliest, but most durable roofing materials with claims of lasting for over half a century or even more. Excellent qualities of rust resistance and thermal reflectivity make it long lasting and energy efficient. Many types of stainless steels are coated with special alloys of zinc and tin, which enhance the properties of strength, durability, energy efficiency and high corrosion resistance even when exposed to extreme harsh and saline weather conditions.

Copper standing seam is another good metal option generally used in high-end posh residential buildings. Fasteners used in copper roofing can only be of copper, stainless steel or brass. We are setting the standard as Phoenix roofing contractor with many successful copper roofing projects in Carefree, Cave Creek, Fountain Hills, Paradise Valley, Phoenix and Scottsdale.

Being biodegradable and recyclable, metal roofing systems are highly eco friendly. Installation is relatively easy as sheet metal can be welded or soldered/fixed with fasteners, whereas factory made metal panels and shingles have easy four way interlocking arrangements for quick and secure installation.

Panel Styles

Metal systems description

There are three general standards for metal systems used for steep-slope commercial roofing applications: architectural, structural metal panels and metal shingles. Generally, architectural metal panel systems are water shedding and are intended for use on steep slopes. Structural metal panel systems are used on low and steep slope. Structural metal panel roof systems can be used on low slope roofs because of their hydrostatic, or water barrier, characteristics.

Because architectural metal panels typically are used on steep slopes that will shed water rapidly over the metal panels' surface, the seams typically are not watertight. Many architectural metal roof systems are well suited for use on slopes of 3 inches per foot (14 degrees) or greater. One exception to the general slope guidelines for architectural metal panel systems is the traditional flat seamed, soldered or welded metal roof system, such as copper. It may be specified on slopes less than 3 inches per foot (14 degrees). Solid roof sheathing, or decking, is required for architectural metal panel roof systems, and recommends using underlayment a very quality underlayment.

Most structural metal panel roof systems are designed to resist the passage of water at laps and other joints, as sealant or anti capillary designs can be used in the seams. Structural metal panel systems possess strength characteristics that allow them to span supporting members. A licensed Arizona roofing contractor must install the system to receive a full manufactures warranty.

Example of a structural metal panel roof system

Metal shingles and shingle panels are available in numerous varieties for use as residential roof coverings. Most of the metal shingles are press-formed during the manufacturing process to provide a variety of shapes. These products can take the shape of individual or multiple asphalt, tile, slate or wood shingle configurations.

Seam types

There are many categories of metal panels. The term standing seam often is used as a generic description for a class of metal roof seams. The name standing seam is derived from the fact that the seams are joined together above the panel flats. The term also is used to refer to a panel profile that includes a standing seam: the vertical leg/flat pan and the trapezoidal seam. The trapezoidal standing seam is more commonly associated with structural metal panels. Other panel types are batten, flat, Bermuda and shingled.

The original batten seam consisted of vertical leg panels placed between wood batten strips and covered with a cap. Today, many batten seam panels are constructed entirely of metal. Because they are designed to shed water, batten seam panels primarily are used in architectural applications.

Example of standing seam profiles

A flat seam is created with individual panels applied in a shingled application. One panel edge is folded back on top of itself; the other panel is folded under, and the two panels are hooked together. Again, because flat panels are considered water shedding, they are more commonly found in architectural installations. Some flat seam panel systems, such as copper, are commonly soldered, which allow them to perform on less steep slopes.

Example of a flat seam

Architectural and structural metal roof panel systems are installed over a large variety of substrates. There are two general categories of substrates: continuous or closely spaced decking that provides solid support for the metal panel, and the other is composed of spaced structural supports (such as purlins) where the metal panels must span between supports. Most structural metal panels are used over spaced structural supports without being supported by a solid deck.

Metal shingles need be installed over continuous or closely spaced wood decking, furring strips, metal or wood purlins using a batten or counter-batten system. These coverings typically are considered to be water shedding systems, so the Slope should be 3:12 (14 degrees) or greater.


Underlayment (or "high temp underlayment" as it is frequently called) is installed over the roof deck before the application of a metal system. An underlayment performs two primary functions: it provides temporary weather protection until the metal system is installed, and it provides a secondary weatherproofing barrier if moisture infiltrates the metal panels.

Underlayments typically are not used with structural metal panel systems when intermittent supports are used to carry the roof systems. However, if there is a continuous or closely spaced deck. We recommend an underlayment be installed.

In locations where the average temperature for January is 30º F or less, installation of an high temp ice and water shield underlayment is critical. A self-adhering polymer-modified bitumen is the best membrane.

An ice and water shield membrane should be applied starting at the eaves and extending upslope a minimum of 24 inches from the exterior wall line of a building. For slopes less than 4:12 (18 degrees), a minimum of 36 inches is recommended. See Figure 1.

Figure 1 - Example of ice damming

We recommend a slip sheet be installed over the underlayment for metal panel systems. A slip sheet is a layer of smooth building paper, such as rosin-sized or unsaturated building paper. Its purpose is to protect the underlayment from damage, as the panels can adhere to and tear the underlayment.

Vapor retarders, insulation and ventilation

Condensation should be expected to develop on the undersides of metal panels. Careful consideration should be paid to vapor retarder, insulation and ventilation issues. Because every building is in some way unique, building owners and designers may need to consult moisture-control specialists.
