How Do I Know if the Roof Coating Coverage is Correct?

This is an important question because many roofing provisions and warranty policies require a specific number of dry coat thicknesses to be applied on the structure. To ensure your roofcoating exposure is correct, you will need a wet mil gauge and the volume solids of the roof coating you are using.

What do you mean by wet mil gauge? A wet mil gauge is a tool that is used to define the thickness of the wet coating after it has been applied to the roof surface. It is simply a gauge with points that is pressed into the elastomeric roof varnishes immediately after it has been applied on the roof. The device is then withdrawn vertically with coating stuck to some of the points. You want to note the deepest points having coating on it and the next deepest points that do not have coating on it. The true wet film thickness is somewhere between the two readings. Once you have determined your wet mil thickness, you then need to know the percent solids by volume in the coating. The wet film thickness is then multiplied by the percent of volume items to give you your dry film width.

Although it is a relatively simple procedure to figure out the actual dry film wideness of your roofing structure, there are three important factors to consider having the proper roof coating coverage for your building or house. First, is the measurement of the wet film thickness immediately after the application of the roof varnishes to ensure the coating does not evaporate or dry, as this would give you wrong measurements. Second, is the wind loss factor when applying roof coatings. A 20 mph winds may result into a loss of 20- 30% of the coating essential. Last, is the need for extra material that could be from 3- 10% of the overall amount of coating required for the structure to account for thickness variations in the applications as well as for the miscellaneous coating remains in the lines and in the vessels.

Achieving the proper roof coating coverage is a very significant step in applying a roof coating process to any building. 

Long lasting Paints for Roofs!

In Australia, there was a huge demand for long-lasting, effectual, cool coatings for metal and tile roofs that could be economically field-applied to houses in the vast Australian continent. We chose acrylic energy saving coatings which are bit expensive but are really very effective. This coating is also comes in liquid format which is very useful while application. A benefit of this coating is that they add 12 to 15-year lifespans to your roof which is cost-savings benefits with twice the lifespan of standard paints. They cooled the buildings dramatically by reflecting away the majority of the sun’s radiation and by releasing a very high percentage of the heat that did find its way into the underlying substrate materials. This is called thermal emissivity.

Other benefits were that these reflective paints required no special processes to apply, while being largely more environmentally friendly and lower in odour. This coating is IR reflective, low toxic in nature, with low Volatile Organic Compounds unlike the liquid, organic-based standard paint tint systems. 

Acrylic Roof Membrane Saves Energy Costs!

Did you know that a dark coloured roof absorbs so much heat that flows not only into the space below it but also back into the atmosphere thereby causing an urban warming or heat island effect. On the other hand, a white rooftop replicates sun’s rays and thereby absorbs much less heat, requires less energy from air conditioning.

Lowered Air Conditioning and Cooling Costs

Acrylic coatings can save as much as 20% or more in energy costs. A reflective roof membrane has the ability to replicate the sun’s UV and infrared rays, allowing the roof temperature to increase only by 12 F. With a lower temperature rise of the cooler roof is a reduced heat transferred to the insides of the building. This relates to a significant decrease in electrical energy demand for air conditioning. After the Acrylic Coatings was applied we definitely noticed a variance in house temperature. It's not a large difference but it is between 15-20 degrees cooler inside the storeroom and rooms. 

Restore your roof for longer period!

Roof painting is a process that restores your roof from extreme temperatures. We should apply roof coating or painting early enough to prevent from structural damage.  The process removes moss and lichen from your tiles and clean drainage by using power washing techniques, which are common in cleaning the pavements on busy High Streets.

The high pressure flow efficiently removes any moss and lichens built up without damaging the tiles.  We will also clean up sewers to make sure the finished job looks as decent as new. 

Cracked tiles and loose filling are replaced to make sure that all tiles, including the important ridge, stylish and bonnet tiles protected are in good condition and are waterproof.  We can then think about applying the protective coating applied to roof. This coating is high performance thermal barrier that uses ceramic technology to prevent the transfer of heat or cold, which comes in a liquid sealant form endowing it with a host of additional useful properties. This coating is easily applied to a number of different surfaces. This roof coating is a breathable Vapour Barrier, as well as an Air and Water Barrier. They helps seal the envelope of any structure making existing insulation in any home or business perform closer to its R-value. This roof painting allows entrapped moisture to escape or be released without damage to the coating or substrate surfaces.

How to prolong lifespan of your roof?

Thermal Barrier Coatings offers reflective roof membranes which not only lower the roof life cycle costs by making the roof last longer but also extend the tear-off date indefinitely. These coatings repair system is unlike a traditional roof in that it is a spray applied massively, coating system that can be applied directly over your leaking and aging roof. This system costs up to 50-70% less money than replacing your roof. With it is an additional value of being able to re-coat your roof every 15 or so years, giving you a new, waterproof, reflective roof membrane with half the cost and time a tear-off would take.

High Performance Roof Coatings

A high performance reflective roof coating has high quality UV blocking materials in order to protect your roof from the leading causes of roof degradation - sun damage from UV and Infrared rays. Not only does the high reflectivity lower air temperature inside the building but also by replicating a majority of the harmful UV heats away from the exterior of the roof, the roof is protected from cracking, splitting, weathering and ultimately from leaking. ThermaCote Coatings has several highly reflective roof coatings that can be applied over almost any roofing surface.

Energy Saving Paints and its Usage

Are you confused about energy saving paints and its usage?

Energy Saving coatings are the best option to save your house from extreme room temperature during different seasons. These coatings act as a thermal barrier and protects from extreme temperatures. These paints are also available in liquid form and are light weight. Properties of these coatings are adhesive sealant, Fire retardant, environmentally friendly. Various products in market are available in the markets which are tested for energy savings. We recommend ThermoCote products which tops in all the categories of energy saving coatings. ThermaCote is tested and certified for energy savings.
