Fastener Compatibility with Profiled Metal Roof and Wall Panels
Profiled metal roof or wall panels rely upon mechanical fasteners to secure the components to a structure. It is very important to select the correct type of fastener for metal construction in order to ensure a strong and weather-tight attachment. This Technical Bulletin serves as a guide for the selection of exposed fasteners used with metal roof and wall panels.

The cost of replacing a roof can be one of the most significant maintenance expenses in the life of a building. USGBC’s Leadership in Energy and Environmental Design building rating program (version 4) assumes a building service life of 60 years. With most types of roofing, building owners can expect to replace the roof once or twice in that amount of time, incurring significant expense to do so.
Many buildings are The Metal Construction Association (MCA) is proud to announce a new study that verifies that coated steel roofs can last as long as the buildings they cover. The research study concluded that the expected service life of an unpainted 55% Al-Zn coated steel standing seam roof constructed today in a wide range of environments using best practices can be expected to be in excess of 60 years.

Using the right tools is key to getting any job done correctly. Contractors and installers who work with metal roofs know how important it is to have the right seamer or a quality screw gun. And architects and specifiers know how important it is to have a good architectural scale and the most current reference manuals.
If you work with metal roofing, MCA has another essential tool for your toolkit: the new Metal Roof Installation Manual. Now available at MetalConstruction.com in the Technical Resources section, this new manual offers 20 chapters of best practices, tips and training for installing metal roofs. The manual covers a full range of useful information about installing metal roofs, including:
Introductory information about roofing materials
Panel types, attributes and profiles
Roof deck substrates
Sealants and Fasteners
Download your copy of the MCA Metal Roof Installation Manual today, and keep the document handy as a reference as you come across questions with your metal roof project. It’ll soon become an essential tool in your toolbox.
And for those of you heading to METALCON 2014 at the Colorado Convention Center in Denver next week (October 1-3, 2014), be sure to check out the great examples of metal construction that Denver has to offer. Here are a few of our favorites that we highlighted in this blog in 2013. Click the links to view the full blog posts:
And the Colorado Convention Center (below) even sports some cool metal work of its own on its facade. Be sure to take a walk around Denver while at METALCON 2014 and take note of these and many more examples of stunning architecture and metal construction.
MCA staff is gearing up for METALCON 2014 at the Colorado Convention Center in Denver, from October 1-3, 2014. Be sure to stop by our booth (#1542) and say hello. We’ll have MCA technical directors Scott Kriner and Andy WIlliams in the booth to answer any technical questions you may have. And the 2014 MCA Chairman’s Award Winners will be announced at the end of the day on October 1st, and will be featured in our booth for the remainder of the show. Click here to view past winners.
We hope to see you there! And be sure to visit these MCA Members at METALCON 2014, or visit MCA’s Product Locator:
We may know the start of 2014 down to the exact second, but the lines between old and new metal design and building materials will continue to blur well into the New Year and beyond. Here are two examples of how metal manufacturers are helping to redefine the true age of metal roofs in a green world.
First, let’s look to Europe where 100-year-old zinc roofs are commonplace, and in particular, at the recently renovated 120-year-old zinc roof on St. Catherine’s Church in Reutlingen, Germany. This roof restoration called for dismantling and removing all the zinc tiles from the roof in order to inspect, clean, and salvage as many as possible. Tiles that were too damaged for reuse were recycled, but inspectors found the tiles that were not exposed to the main west-facing wind and weather were nearly all reusable. The remaining roof was re-clad with RHEINZINK 0.7mm square tiles, using 1,500 PrePATINA blue-grey 330mm x 330mm tiles.
Located at the old cemetery, the Gothic Revival-style church is now preserved to its original state, circa 1890. RHEINZINK says that with the service life of zinc products expected to last 80–100 years for roofs and 200–300 years for walls, the roof tiles will be around for New Year celebrations for generations.
Stateside, a new LEED Platinum home in Glencoe, IL, features an unusual look for a LEED home—traditional rather than modernist design, allowing the home to complement its neighborhood. The standing seam metal roof was a key element of the sustainable design. About 600 sq ft of 24-gauge PAC-CLAD material from Petersen Aluminum, Elk Grove Village, IL was used. The Silver Metallic Kynar 500 coating offers high reflectivity and SRI (solar reflectance index) ratings and is Energy Star approved.
The roof provides many green features. Its shape is asymmetrically arranged to collect as much storm water as possible. It is also sloped at two different angles—a summer and a winter angle. The steeper, south facing roof supports solar thermal panels, which are optimal for the low winter sun. The shallower south facing section of the roof includes solar PV panels, which maximize electrical production during hot summer days.
“When our client said ‘give me a roof that I will never have to replace,’ we thought metal immediately,” said Nathan Kipnis, AIA, principal of Kipnis Architecture and Planning, Evanston, IL. Meanwhile, general contractor, Scott Simpson, president of Scott Simpson Builders in Northbrook, IL, says that, beyond this project, he recently used an old metal barn roof on the interior walls of a renovated—and much beloved—bakery in Evanston.
We’re getting in the Halloween spirit here at Metal Construction Association, and we’ve found some fun lists of the most haunted places. But we thought we would put our own spin on putting together a list of haunted places: the top five haunted places with metal roofs!
Mount Washington Resort – This elaborate Bretton Woods, NH hotel–with its distinctive red metal roof–opened in 1902 and is rumored to be haunted by the ghost of Carolyn Stickney, the widow of the hotel’s original owner. According to legend, caretakers have sighted the ghost of Mrs. Stickney descending stairs and switching lights on and off.
Beetle Juice House – This fictional home from the film Beetle Juice is the setting of the 1980’s classic horror/comdedy movie starring Michael Keaton, Winona Ryder, Alec Baldwin and Geena Davis. The home, which played a central role in the film, featured a white standing seam metal roof before and after the garish renovation that irked the recently-departed owners.
Tower of London – The tower, one of the most famous landmarks in London for almost 1,000 years, has no shortage of alleged hauntings. Perhaps the most famous ghost thought to reside in the tower is the spirit of Ann Boleyn, a wife of Henry VIII who was behaded in the tower in 1536. The tower’s lead roof has helped the structure survive more than nine centuries, though lead roofs are no longer commonplace for obvious reasons.
Quitman, AR Residence – This turn-of-the-century victorian house that features a striking metal roof went on the market in 2012, and was marketed as having a “friendly” paranormal presence. Previous owners and visitors reported more disturbing happenings, but the most recent owner claims to have had minimal interruption.
The Dominion Building – This Vancouver, Canada building, completed in 1909, features a mansard roof made of metal. The building is said to be haunted by the architect, John Helyer, who is rumored to have fallen to have fallen to his death when the building was opened. This has been dispelled as myth, but many report hearing his steps in the stairway.
We hope you’ve had a little fun with our twist on a list of favorite haunted buildings. Have a happy Halloween!
