The white color, along with the increased insulation provided by 1” ISO board will help keep the 2 nd-floor rooms the roof is covering much cooler in the summer and cozier in the winter. The TPO costs a bit more than traditional epdm (rubber) but it is more durable. Finally, we recommended white TPO for the flat roof sections. Beyond that, having the existing roof remain provides an excellent secondary protection in the event of a leak or wind-blown issue with the new roof. This was a great solution for the church in that it saved them the cost of removing the existing roof and also kept the church dry throughout the process of installing the new roof. After evaluating the structure, we showed them that the existing framing would be able to support a new roof built directly over the existing roof.
The Church Board had already decided that they wanted to go with another standing-seam roof. The built-in gutters were leaking at various points. The flat roof sections, while not original, were also showing significant wear including cracks at many seams. The existing standing-seam roof on the church was the original from the 1950’s and was beginning to show significant wear. That is a smarter option for those with a different style in mind for their property.īut no matter what you are looking for, Metal Master Shop has what you need.What an outstanding opportunity Eby Exteriors had to replace this Standing-Seam Metal roof on this large church roof near Lansdale, PA.
We have some that aren’t copper but look like it, so they will have the same appearance as a new copper roof but won’t develop the patina as time goes by. Quite frankly, if you don’t like the look of patina on a copper roof, I would suggest that you get a different metal. This “armor” isn’t just chemical, but physical as well because the patina literally adds layers to the roof, making it physically thicker.Īs you can imagine, in the Miami, Florida weather, anything you can do to make your roofs more resistant to the elements is a good thing! It will help your roof last longer than if you routinely clean the patina off. The very things that change the copper surface initially, make it stronger against those same corrosive materials. The patina is like an extra protective layer of armor against the elements.
While many love the look of a copper roof with a full patina, it’s also very beneficial for your roof. But this artificial enhancement doesn’t always achieve the same look as a natural progression. If you want to speed up the process or assist it in developing more evenly, there are some chemicals that can be painted or applied to the roof. As with everything else in Miami, we move fast! A patina will form on a copper roof here far faster than it will in a drier climate.Īlthough this process takes time, it starts immediately after the copper is first exposed to the elements. Likewise, depending on the climate, patinas will develop faster or slower. The top of the roof will have the least amount of standing water because of the incline, for example, so it may turn green more slowly than other areas. Because of these varying conditions, the patina will form unevenly.Īs you can see in the picture, the patina is only visible in certain areas. The patina develops based on exposure to oxygen, water, and chemicals.
Even old wood furniture can get a sheen of oxidation in time. Other metals can acquire a patina as well. It’s a process of oxidation that happens over time that turns copper green. The patina that forms on copper roofs is a result of weathering and changes in the chemical composition of the metal. I say “again” because looking back at history, it’s been used for many centuries as a favorite roofing material.
