Hard to Find Leaks? Look Where It Has Had To Travel.

A large junior high school had experienced numerous leaks. Leaks are always a challenge as water can travel a distance before finding a place to enter

the building. For this junior high school, the difficulty level was high.


Over the years, the school had done its best to maintain a solid roofing system. This time, they needed a new roofing system. During our evaluation, we found that the school had 2 roofing systems, both were gravel based. This was one of the primary reasons why leaks were hard to find. In addition, the school needed to be in State code using an R20 or R30 insulation.


Showalter removed both gravel roofing systems, stripping it down to its deck. We placed proper insulation that met State regulations and sealed it with a TPO roofing system known for its longevity and energy efficiency.



What Poor Workmanship Can Do to a Building

full article:  You’ve read it on proposals…you’ve heard it from the sales rep…you’ve come across it on websites….quality and  workmanship. Do you pay attention when a company touts quality and workmanship? Do you assume that quality and workmanship will simple be there at the end of the project?

Original Roofing System

We recently came across a roofing job that proves workmanship and quality really does matter. The current owner of an 80,000 sq ft facility was told that the roof was newer and in great shape. They took their word for it.

“A couple years after the purchase, part of the roof blew off exposing the poorest workmanship and decision making that I’ve seen in years,” shared 27 year veteran, Joel Showalter, Commercial Division Director.  What they found was astonishing: a modified bitumen roof was installed over a gravel roof.

After informing the new owner of the findings, we learned that the roof was experiencing a high quantity of water leaks. Understandably, the roof was installed with such poor workmanship and with hardly any manufacturer specification  followed. They tried patching, but with such a mess under the surface, it proved difficult to keep the water out.

Showalter Roofing was tasked with bringing the roof back to a healthy state. We removed both layers of roofing material and  replaced over 300 panels of gypsum deck. We installed a mechanically fastened PVC Roof System as per manufacturer’s specification that is not only durable but very energy efficient.

 There is something to be said for quality work and superior workmanship.         

Changes from Winter to Spring on Your Roofing System

Buildings in the Midwest experience the most changes of hot and cold temperatures, high winds, and hail. If the heat and humidity expands and cool weather contracts, what affect does that have on a roof? Your roofing system acts and reacts the same way to the temperatures.

Let’s begin with winter since we’re at the end of the season. Winter has the tendency to cause the material to shrink in size due to cold temperature. When it snows, it finds its way to those small cracks and crevasses and fills up that gap with water and/or ice. When the weather starts to warm and the materials on the roof warm up due to the temperature, expansion begins.

The water on the roof needs to go somewhere. Many times the water simply gets evaporated and there’s no cause for alarm. However, if there is a weak spot on the roof, the water will certainly find it. When it does, the water travel inside the building. This is where the trouble starts.

Out of Site, Out of Mind

Because the roof isn’t seen every day to visually inspect its wear and tear, the old cliché ‘out of site, out of mind’ applies. Understandable. But before your building gets wet, and mold has an opportunity to grow, get it inspected once or even twice a year before the change of seasons.

Well that was Obvious!

There are some obvious places to begin searching on a roof for leaks. We begin by inspecting the roof for standing water or damp spots. We test the area. Next, we search for drains, stacks and inspect the flashing along the sides. We test these areas.

Next, we search for material changes and shift in position. Even the smallest shift produces a hairline crack. That’s all water needs is a small crack. Once we identify these areas we’ll seal them off with special water resistant materials. Now when it rains or snows again, your roof and all of its vulnerable areas are protected.

But don’t be fooled, it’s off to find the next weak spot as soon as the opportunity arises. That’s why inspections are so important to the life of your building. It’s a minimal investment that has long standing results.
