North Carolina is famous for storms of all types. The mobile home pictured below is in Snow Camp, North Carolina had was damaged by a tornado. Thankfully the owners didn’t get hurt.
The original roof was a typical low-slope shingled roof installed correctly over the front porch and home. We see these roofs, as well as metal roofs everywhere in the state, and appearance-wise, they look nice, however, there is a downside…. and that is when a storm such as this one, the damage far exceeds that of a factory-built mobile home when first purchased.
When you look at the pictures you will see that the original roof was separated at the seams and a 2×4 rafter was lodged into the roof. Nail holes and screw holes were everywhere and the insurance company was calling it a total loss.
You might think that is great due to the amount of damage, however, the settlement for this loss doesn’t come close to the price of a new mobile home.
When we received the call from the owner to come to look at the damage, this is what it looked like. Pieces of the roof are scattered across the yards of multiple properties. Holes in the roof from 2×4 rafter pieces, holes everywhere from nails and screws ripped out from the extreme winds.
There are numerous types and products when it comes to roof coatings.
Cool Roof Coating:
A cool roof is designed to reflect sunlight so that less heat is absorbed by the building. Most commercial and industrial buildings benefit from cool roofs, but building owners should consider climate factors before deciding to install one.
Similar to how wearing light colors can keep you cool on a sunny day, cool roofs use bright solar-reflective surfaces to maintain lower temperatures. A standard dark roof can reach temperatures of 150°F or more in the summer, while a bright white cool roof under the same conditions can stay 50° cooler.
“Coolness” is measured by two properties: solar reflectance and thermal emittance. Both properties are measured from 0 to 1. The higher the value, the cooler the roof.
The Benefits of a Cool Roof
- Reduced energy bills by 10%-30%
- Improved comfort for indoor spaces without air conditioning
- Lower maintenance costs
- Extended roof life
- Reduced Urban Heat Island Effect (occurs when an urban environment is hotter than surrounding rural areas due to black surfaces)
- Less peak electricity demand which helps prevent power outages
- Alleviated air pollution and global warming concerns by lowering CO2 and other emissions
Once we did all of the metalwork to bring back the integrity of the metal, seams, and holes, now it was time to install the new roof coating.
4 Step Roof Coating
This part, you might be thinking would be the easiest steps…..Not True.
1. SURFACE PREPARATION
The roof surface is pressure washed to remove all dirt, dust, and other foreign contaminants. This step ensures maximum adhesion of the system to the roof substrate. In some cases, the use of a primer may be necessary. Any problem areas found during surface preparation must be properly addressed before the system can be installed.
2. SEAMS & FLASHING DETAILS
All seams, fasteners, penetrations, drains, and other flashing details are treated with Acrylic Brush-Grade 220 or Acrylic Butter-Grade 221. These highly flexible waterproofing mastics enable the system to withstand the natural expansion and contraction (thermal cycling) of the roof structure. This step of the application process is critical, as the “details” of a metal roof are generally were leaks occur.
3. BASE COAT APPLICATION
An ivory-tinted base coat of Acrylic 211 is applied. This highly-advanced acrylic coating ensures applicators maintain uniform mil thickness throughout the system and is uniquely formulated for maximum adhesion to metal roof surfaces.
4. TOP COAT APPLICATION
A bright-white top coat of Acrylic 211 is then applied. This acrylic top layer forms a seamless and flexible membrane that provides the system with superior durability, reflectivity, weatherability, and mildew resistance.
We use the best products from top manufacturers, going thru training for every product to be installed. In the roof coating process with this job, the Mil Thickness for each material applied had to meet the exact standards required by the manufacturer, any part not done to the correct gauge would not meet warranty requirements.
