STONE-COATED STEEL ROOF
For our Mega Build project we wanted a roof that is wind, hail and fire resistant. It is in an area of the country that’s famous for its severe weather—especially tornadoes, thunderstorms and intense hail storms. For that reason, and because we’re building this house to last for generations, we decided to put a stone-coated steel roof from Gerard on the Project house.

This magnificent slate-colored roof was installed by Horn Brothers, a nationwide roofing company based in Norcross, Georgia.

Some concrete and ceramic tile roofing material can compare with steel for resistance to damage from hail, but for our Mega Build, we wanted to install a light weight, long-lasting roof—one that would not require us to adjust our framing specifications in order to support the weight. Our stone-coated steel roof weighs about one-eighth as much as a concrete or clay tile roof. This becomes a significant factor in earthquake-prone areas, where heavy roofs can create structural problems and increase the likelihood of personal injury in case the structure fails. The Gerard stone-coated steel roof weighs about 1.4 pounds per square foot. This roof also has a 50 year, transferable warranty to withstand winds up to 120 miles per hour and hail protection up to two and a half inches.

We also liked the fact that the batten grid structure that undergirds Gerard’s stone-coated steel shingles allows for about an inch of air space which acts as an excellent insulator, increasing the energy efficiency of the house.

THE GERARD ROOF
The steel that is used in these shingles is 26-gauge, coated with Zincualume corrosion inhibitors, epoxy primers and other protective layers to provide a shingle that will not crack, break or curl. Then a thick coating of ceramically-fired earth-stone granules are applied, to add beauty and resist the harmful effects of sun, wind, rain, snow, and of course, hail.

Electric Shock or Electrocution due to Ground Fault – this is when an electrical current “Leaks” out of a line to the ground. Anytime electricity makes contact with water (in a kitchen or bathroom, near a pool or spa), the current “leaks” into the water. The current leak could be enough to kill someone in contact with that water but still not be large enough to trip a circuit breaker. Standard circuit breakers guard against overloads and short circuits. They’re not designed to protect people from electrical shocks. Hundreds of preventable electrocutions happen in and around homes every year. Electrical outlets in wet areas (kitchens, bathrooms, outside near pools, etc) pose the greatest hazard. Electrical Fire due to Arcing – this is when a current “Jumps” through the air from one place to another, causing a free and uncontrollable flow of electricity. That uncontrolled electricity can start a fire inside your walls that can literally burn your house down from the inside out. Our segment featured a “Jacob’s Ladder” – it looks like a contraption from Dr. Frankenstein’s laboratory – to illustrate arcing from one wire to another. Arcing can occur with damaged or frayed extension cords. It can happen if an electrical outlet is improperly installed or gets damaged. It can happen if you drive a nail into a wall to hang a picture and you pierce a wire hidden in the walls. Damaged or destroyed electronics due to Surges – This is when the voltage in an electrical system “Spikes” or “Swells” as it travels through wiring into everything plugged into that wiring. Lightning storms cause major surges (up to 6000 Volts or more). Utility companies cause controlled surges as they alter systems to meet demand. Motors on appliances like the fridge or the AC cause mini-surges (1000 volts or less) when they turn on & off. That can slowly break down wiring insulation, leading to faulty operation or failure of appliances. The average home experiences hundreds of these small surges every day. All these problems can be solved at the Breaker Box – electricians call it the “Load Center”. Let’s first take a look at a standard circuit breaker: A Circuit Breaker is a safety feature that interrupts the flow of electricity (“breaks the circuit”) whenever it senses trouble within your home’s electrical system. Most circuit breakers have a thermo-magnetic function. The thermal part of the breaker senses any overloads that can heat up an electrical line. If you plug too many appliances into a single circuit, that overload will heat up the wires in that circuit and that buildup of heat will trip the breaker. The magnetic part of the breaker senses a short circuit and trips the breaker to cut power to that circuit. A short circuit means that the power has found its way to ground in an unintended manner (if two wires in a wall switch accidentally touch for example). The power has been short-circuited and will trip the breaker, interrupting the flow of electrical current. Surge Arresters plug into the breaker box just like a standard circuit breaker. It works like the surge protector you plug your computer into, but it senses and stops surges throughout the house. It not only protects the electronics you’d protect with a plug-in surge protector, but it will protect the hard-to-reach appliances (like a wall-mounted microwave) that you might not be able to reach with a plug-in surge protector. Ground Fault Circuit Interrupters (GFCI) also plug into the breaker box just like a standard circuit breaker. Your house should already have GFCI receptacles anywhere in the house where water is present (bathrooms, kitchens, outside near the pool, etc.). GE’s GFCI breakers work better than GFCI’s on individual receptacles because one GFCI breaker will protect all the receptacles connected to that circuit. For example, if you have 7 outlets connected to a single circuit in a bathroom and one of those outlets experiences a ground fault, the GFCI breaker in the breaker box will shut power to all 7 outlets. Arc Fault Circuit Interrupters (AFCI) – Because arcing occurs at levels lower than conventional circuit breakers or fuses are designed to detect, sporadic arcs can go undetected for extended periods. As heat from arcs climbs to 5,000 degrees Celsius and higher, wire insulation and other nearby materials grow more susceptible to fire. You cannot prevent an arc fault from occurring inside your walls, but you can stop that arc. An AFCI breaker electronically detects any arc faults and stops the flow of electricity to that circuit in a fraction of a second. No electricity means no heat, and no heat means no fire. By tripping a breaker on a specific circuit, that AFCI breaker helps you identify the source and location of your arcing problem right from the load center (the breaker box).$
