ROOFING

LONG SPAN ALUMINUM ROOFING SYSTEM

Aluminium Roofing

In recent years, aluminum roofing has grown quickly in popularity because of the many advantages aluminium roofs offer to homeowners. Aluminium roofs are attractive, durable, energy-efficient, and increasingly affordable. In the past, aluminum was not a popular roofing material for cost reasons and because of concerns about the structural limitations of aluminium. Latest innovations has resolved the structural problems and decreased the cost of aluminium.

Benefits of Using Aluminium Roofing

Aluminium is increasingly valued as a roofing material for many reasons. Aluminium is attractive and malleable and comes in a great variety of roofing types and designs.  It could be offered in a wider range of gauges than steel. Aluminium can be formed into individual tiles or shingles or shaped into panels that mimic the look of shingles. It is also lightweight and easy to work with onsite, reducing labor costs for installation. Once installed, one of aluminium's most important advantages is its great durability.  Aluminium roofing does not warp, crack, or burn and, unlike steel, it is extremely corrosion-resistant and does not rust.  A significant advantage in coastal areas and with a great deal of precipitation or problems with acid rain.

The Environmental Benefits of Aluminium Roofing

Like other types of metal roofing, aluminum is also extremely energy-efficient. Studies have shown that metal roofs absorb 34% less heat than traditional asphalt shingles, reducing air-conditioning costs in summer, and, depending on the part of the country, homeowners who have switched to metal roofing have reported savings of up to 20% on heating and cooling bills. In addition, aluminium roofing is typically made up of 90% recycled material and is itself fully recyclable when necessary, making it one of the most environmentally sound building materials.

Aluminium Roofing - Costs Now vs. Costs Later

Aluminum's primary disadvantage is its cost. Aluminium's initial installation is more expensive than more traditional roofing materials like wood or asphalt shingles. However, over its life cycle, aluminum has been shown to be extremely cost-efficient. Most traditional roofing materials must be replaced every 10-12 years. Aluminium roofing can last 100 years or more and is not subject to the corrosion problems of steel. If you install aluminium roofing, there is a very strong chance that you will never need to install a roof again.

Disadvantages to Aluminum Roofs 

Aluminium is also less hail resistant than steel, especially on lower-grade roofs, but

unlike some traditional roofing materials, it will not split or break. Finally, because of the recent rise in popularity of aluminium roofing, not all roofers are experienced with aluminium roofing installation

Beauty and Durability

Metal roofs once got a bad rap for their bright shiny colors and metallic look, but finishes are now much more compatible with home exteriors. Metal roofs have lost their “barnyard” image and now sport a host of colors, matte finishes, and profiles. Virtually any color is available, the metal can be finished to remove that “high gloss” metallic look, and the end product can be formed to resemble any roof product from tile to asphalt shingles or cedar shakes. Distressed-look metal roofs have an irregular pattern so that heavy hail storms won’t affect the surface appearance of thereof.  Dave Uppgren, a principal in Uppgren and Associates, the architectural firm that covered Domino’s Pizza headquarters in the largest standing-seam copper roof in the U.S., likes copper roofs because they are beautiful, durable, and almost maintenance-free. “About 90 percent of the decision to use copper for the roof was based on aesthetics,” Uppgren says of the stunning installation. “There really are no maintenance problems. As with any metal roof, snow sliding off can become a big issue and we’ve probably spent more time preventing snow from falling onto the public areas than to repair leaks.” 

Installation

Installation of long span metal roofs is best left to the pros. “The biggest problem with any metal roof is expansion and contraction over long distances,” Uppgren says. A good roof system is designed to accommodate that movement. Roof components may be manufactured on site or arrive as pre-formed metal panels. Connections are made from underneath with clips. The best metal roofs do not have any fasteners applied from above because every hole made in any roof can lead to leakage.
Metal roofs are prone to a condition called “oil canning”. Tension irregularities during crimping can result in wrinkles or waves on the flat face of the roof. Ask the roofers how they avoid it, if there is a system of checks designed to eliminate oil canning, or how they will respond if it occurs. Since it is a common condition addressed by manufacturers and roofing systems, a good installer should have a ready response.
