#40 – Step Flashings and Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

I recently had an interesting conversation with a contractor who has installed traditional roofing for many years. He was familiar with a concept called step flashing that is used with many types of roofing. Step flashing may be used alongside a chimney or wall where the roof intersects it. Step flashing is a series of […]


#39 – Should Shingles be Removed Before a Metal Roof is Installed?

Filed under: Metal Roofing 101 Series, Roofing Help Videos

Metal roofs are much lower weight than most other roofing materials. Aluminum roofing weighs around 50 pounds per 100 square feet and most steel roofs are 80 – 100 pounds. Traditional shingles for that same size area are 275 – 425 pounds in comparison. This encourages the installation of metal roofs over existing shingles. Additionally, […]


#38 – Interlocking vs Overlapping Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

There are metal roofing panels that simply overlap on the vertical and/or horizontal seams, and metal roofing panels that actually interlock wherever they connect. There are obvious benefits to fully interlocking panels. Those benefits typically include increased wind resistance and less chance of weather infiltrating the roof system. Over time, with overlapping panels, ice, snow, […]


#37 – Fasteners and Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

When investigating a metal roof for your home, you’re likely to hear about exposed fasteners or concealed fasteners. The terms are self-explanatory but which is better? Some metal roofs are designed so that all of the screw heads are exposed. They are visible and exposed to the weather. Other products are designed with concealed fasteners […]

Filed under: Metal Roofing 101 Series, Roofing Help Videos

As a building products manufacturer, there are few things that we can do to help you control the cost of living but we can help you control the cost of maintaining your home. Re-roofing a home every 12 – 20 years depending upon your climate does not have to be a way of life. A […]


#35 – Condensation and Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

I was actually in this industry for quite a few years before I really understood condensation in a building and how a metal roof might impact it. In fact, I always sort of thought that metal roofs would regularly get condensation on the back side of the panels – between the metal roof panels and […]


#34 – Complex Roofs and Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

We often get asked whether metal roofing materials are applicable for complex roof lines. Recent years have seen a move away from cookie cutter ranch and split level homes to homes where the roof lines are very cut up with different angles, hips, valleys, dormers, and so forth. Metal makes a great option for these […]


#33 – Chimneys and Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

One of the positive benefits of a properly installed metal roof is that it will be flashed in order to be watertight against roof penetrations such as chimneys, skylights, and dormers. Shorter term roofing systems are often just sealed in those areas, with the assumption that the sealant will last as long as the roofing […]


#32 – Can a Metal Roof be Repainted?

Filed under: Metal Roofing 101 Series, Roofing Help Videos

There are times when building owners become interested in repainting their current metal roofs. This may be to freshen up the building or to give it an entirely new look and color scheme. Most quality metal roofs have finishes that are warranted for 40 or more years. Repainting of course will void any warranty that […]


#31 – Should a Metal Roof be Installed Over Battens?

Filed under: Metal Roofing 101 Series, Roofing Help Videos

We frequently are asked whether metal roof should be installed on batten’s or direct to the roof deck. By design, some metal roofs must be installed over battens, some must never be installed over battens, and some can be installed over battens or over solid decking. So first and foremost, it’s critical to choose the […]
