Arizona has the highest nationwide concentration of a flat roof material called cementitious – an acrylic and cement mix. According to local experts, there were billions of feet of cementitious roofs installed 15 to 25 years ago, and now these aging roofs are all starting to crack and fail.
Phoenix, AZ. “I never cease to be amazed at how such a thin layer of only 30 mils of veggie-plastic coating can add up to 25 years on a flat roof’s lifespan,” commented Castagra Products Inc. CEO, Peter Roosen.
“Building owners and managers want to put off, indefinitely, what actually used to be inevitable, re-roofing, which is extremely costly. Now, with some modern membranes and coatings such as ours, flat roofs can, with low cost inspection regimes, last for the life of the building itself.
Vigorous spudding can do more harm than good, especially with fragile substrates such as those often encountered with tar and gravel roofs.
Roofers are very familiar with the long-handled tool with a stiff flat blade on one end (usually 4″ or 6″ wide) that is used to scrape and remove the top surfacing of a roof down to the membrane. There are also some very powerful mechanical spudders.
Tar and gravel roofs (Built-up Roofing) have been a popular choice for many decades and generally have a 10 to 15-year lifespan in cities like San Diego. But, with the crack down on noxious fumes (VOCs), they are giving way to modern membranes and coatings, especially with the rising demand for cool roofs.
With the ever increasing performance levels of solar panels, home and building owners want their roofs to be high performance with a longevity to match or even surpass the lifespans of the electricity generating systems they support.
Castagra will be exhibiting at the Colorado Roofing Association Show on January 24, 2019.

This updated case study concerns a movie theater chain building’s asphalt roof in Avondale in Phoenix where high UV, temperature extremes and often violent storms, give coatings and membranes, a mix of some of the hardest conditions in the entire nation.
At the end of the day, success is measured by coating pros adopting Ecodur as the go to solution for their customers who regard the highest green credentials as a basic requirement along with top performance. One of the most discerning markets in the nation is San Diego, arguably the solar capital. Many thousands have invested heavily in solar and demand contractors use the best and greenest roofing materials. This article reflects all that…..
Even specialized coatings, created specifically for controlling this phenomenon, have had mixed results, that’s why the performance of our Ecodur on asphalt roofs with cool topcoats in Phoenix, during the past two years, has exceeded our expectations.
