#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 […]


#30 – The Durability of Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

Most people buy metal roofs for their longevity. Once a homeowner reaches the point of owning their “forever house” – the last house they will ever buy, and perhaps they even have plans to pass that house on to loved ones – it makes sense to end the crazy cycle of re-roofing every few years. […]


#29 – Skylights on Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

Normal types of protrusions through the roof such as skylights and chimneys do not pose a problem for metal roofs. They need to be flashed and detailed properly and quality metal roofing manufacturers will have instructions to help installers with that. Skylights must be curbed, not flush-mounted with any metal roof. If there are existing […]


#28 – Minimum Roof Pitch with Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

Most residential metal roofs require at least a 3:12 roof pitch and have no maximum roof pitch. That means there is at least 3” of vertical rise to the roof slope for every 12” it goes back horizontally. That is a 14 degree angle. Mechanically seamed standing seam metal roofs, commonly used on large warehouses […]


#27 – The Energy Efficiency of Metal Roofing

Filed under: Metal Roofing 101 Series, Roofing Help Videos

If you’re thinking of a new roof for your home, it’s important to consider energy efficiency. Choosing a roof that will reduce your home’s energy costs is a huge ongoing benefit. Metal roofs offer energy efficiency in three ways and the important thing is that all of these ways are long lasting – they do […]


#26 – Lightning and Metal Roofs

Filed under: Metal Roofing 101 Series, Roofing Help Videos

When considering a metal roof for your home, please keep in mind that while metal conducts electricity, it does not draw or attract it. Lightning hits the highest object around, regardless of whether it is metal or some other material. The Metal Construction Association, on its website, metalconstruction.org, has a great technical bulletin that explains […]
