Caution to Contractors: Bending Techniques for Aluminum Differ from Steel

When metal roofing manufacturers first introduced aluminum material for standing seam roofing, much of the aluminum produced was .032 thickness.

However, over the years the building products industry has been gravitating to thicker roofing and trim material, especially in aluminum. And, Dade County Florida enacted new wind uplift rules for metal roofing that required the use of .040 aluminum for roofs and .050 thickness for trim material to meet the rule requirements.

Consequently, contractors were transitioning from the use of .018 to .024 thick Galvalume or Hot Dipped Galvanized steel roofing and trim products to .032 to .050 thick Aluminum. Many contractors assumed aluminum bent the same as steel and therefore thought little adjustment was needed to make crisp bends on aluminum as they had done with steel. This resulted in some contractors bending these heavier aluminum products beyond their tensile strength limits resulting in cracking of the metal and paint as well as leaving a silver look from the crazed aluminum under the paint.

Compelling Data that Supports Metal Roofs Offer Longer Service Life

New industry research shows that metal roof systems can last at least 60 years, longer than the average commercial building’s service life.

“The study provides third-party, scientific data that backs up the long held belief that 55% aluminum zinc coated steel standing seam roofing systems offer economic longevity and can be better for the environment.

Non-metal roofing systems require one or more full replacements within a typical commercial building’s 60-year service life, which is more expensive over the long run and usually adds to the solid waste stream in landfills.

The study, sponsored by the Metal Construction Association and the Zinc Aluminum Coaters Association, was conducted with oversight of three independent consulting firms which analyzed low-slope, unpainted 55% Aluminum-Zinc coated steel standing seam roofing, in a wide range of environments across the U.S.

The material tested is commercially known as Galvalume and Zincalume and is commonly used on low rise commercial buildings such as warehouses, schools, distribution centers, shopping centers, government structures, sports and exposition facilities and other structures. Continue reading

Looking for a Metal Roofing Contractor? Here Are Some Things to Consider That Should Help You Make the Right Choice

Not all metal roofing contractors are alike. Some are big, national companies with the ability to coordinate and staff a wide range of residential and commercial projects. Others are small family-owned companies with a couple of full-time people who hire part time workers depending on the size of the job.  Regardless of the size, you want a company where the professionals will deliver a quality metal roof system at an honest price. Here are some questions you can ask and some guidelines you can follow to help you make that choice:

1. Make sure the metal roofing contractor licensed. Many states require a roofer be licensed in the state; however, all states are different. Check the code requirements in your area. And be sure the roofer’s license is up to date. Continue reading

Stay Clear of These Asphalt Shingle Roof Problems with a Standing Seam Metal Roof

We all know that an Englert Kynar coated standing seam metal roof will not chip, crack, peel, chalk or fade if properly installed on your home or commercial building. And the color you’ve chosen will remain crisp decades from now.

If only the same could be said for an asphalt shingle roof. The simple fact is that because of the kind of material used in shingles, there are many more possibilities for problems.

For example, cosmetic asphalt shingle roof problems such as shadow lines, blistering, uneven surfaces and improper randomizing of shingle bundles leading to color patches on the roof—are potential problems you can face if you install a shingle roof. Continue reading

A Log Home and a Standing Seam Metal Roof: Perfect Together

There’s a reason why all the log home manufacturers feature these magnificent log “cabins” with equally sophisticated metal roofs—they know they are the best possible choice for their product both aesthetically and functionally.  Just as log homes are renowned for their natural look and low-maintenance, a standing seam metal roof system will last as long as your log home with minimal upkeep and provide the same rustic, natural architectural aesthetic as your home.

Standing seam on a log home has its practical values as well. Many log homes are built on lakes and in heavily wooded areas—often remote from the hustle and bustle of urban and suburban life. If you own such a “cabin,” odds are good you’re dealing with conditions like heavy snow, the potential threat of wildfire and remote access. Three very practical reasons your log home should be capped with a metal roof. Continue reading

End Your Flat Roof Commercial Building Snow Problems with a Retrofit Standing Seam Metal Roof

If you’re planning major renovations to a flat roof commercial building in the Northern U.S., you may want to take into consideration that flat roofs — particularly older ones — don’t handle snow accumulation very well, particularly if they have a poorly designed or blocked drainage system.

That’s particularly true on the East Coast where snow tends to be wetter and denser than the western part of the country. If your building is getting a complete makeover,  consider installing a steep slope metal retrofit roofing system that will provide a long-term solution for your snow and drainage problems. Steeper roof slopes shed snow more effectively. That’s why greater roof slopes are common on commercial and residential buildings in the northern states and in mountainous snow-prone regions. Continue reading

Metal Roofing and Gutter Contractors… It Pays to be Aware of and Utilize Best Practices When it Comes to Insurance and Job Safety

We know from experience that roofing and gutter contractors of every size will find just about any way they can to save a nickel here and a dime there on every job they do.

It may be on the cost of material, or their labor, or even on the cost of gas to get a truck from customer A to customer B.

But one place they almost never look to save money is the business insurance and the premiums they pay for it to handle liability or loss of property. Continue reading

The Abc’s of Standing Seam Metal Roofing: Structural And Architectural

Standing seam metal roofing systems can be divided into two basic categories: structural and architectural.  Structural and architectural systems are designed, engineered and installed to satisfy different metal roofing requirements.

Architectural metal panel roof systems and structural metal panel roof 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 roof 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 roof deck. Continue reading

Design Your Standing Seam Metal Roof for Optimal Performance in Cold Weather Climates

If you’re planning on installing a new standing seam metal roof and you live in a cold weather climate with snow, keep in mind some design considerations that, in the long run, are sure to protect you against problems with snow and ice accumulation and removal during the winter months. Here are some tips:

  • Choose a design with a cold roof. Keep the entire roof as cold as the eaves. Ventilating the underside of the roof, insulating the attic floor, and plugging air leaks are usually the answer.
  • Consider a roof color with a high solar absorption value that will help thaw snow and ice.  Colors such as bronze, brown, or dark gray versus white or light earth tones will help do the trick. Continue reading

Drip Edge: Insurance Against Those Wet Roofing Woes

Your existing shingle roof has had it and you’ve decided to replace it with a standing seam metal roof that will last twice as long and add value to your home when it comes time to sell it.

Aluminum Drip Edge from Englert is available in 4" and 6" sizes.You’ve gotten bids from two or three roofing contractors and you’re almost ready to make your decision. Most homeowners will trust their roofing contractor to do what’s necessary to replace the old roof but it doesn’t hurt to ask if your roof bid includes drip edge. A drip edge is a metal (usually aluminum) strip which extends beyond other parts of a roof and directs rainwater off the roof away from the fascia and into the gutter. The edge is configured so it prevents water from blowing under your roofing. At the same time, a lip along the edge makes water drip down out and away from your house, instead of directly down the side of the wall or fascia. In effect, it is an effective way to prevent water damage all the way from the roof to the foundation.

A drip edge provides a neat, straight edge to the roof, and is positioned so that roof water drips in the middle of gutters, along their full length. This is important because a badly positioned drip edge—or no drip edge at all– can cause overflowing of gutters, over front or back.

Sometimes, a roofing contractor will charge extra drip edge, particularly if he is hand cutting and bending the material which does take a little more work, time and skill.

But drip edge is available from manufacturers like Englert already pre-manufactured in 6” and 4” wide, 10-foot strips for new construction and retrofit roofing projects respectively to save the contractor labor costs in cutting and bending metal. Nearly every roofing contractor will vouch that drip edge is giving your home extra protection. And even home exterior painting contractors who have painted miles of fascia board with and without drip edge will tell you the paint job and wood always fair better when there’s a drip edge to help protect them.
