It’s a bit surprising how many homeowners fail to maintain their roofs and allow dust, mould and leaves to grow. In addition, they suffer damage from the weather and sun that is not addressed. To safeguard against water damage and other environmental damage the painting of roofing plays an essential part.

The intense UV levels in Sydney and the surrounding suburbs is only one of the many things which a well-designed paint job will help to protect. Making sure you do it right first time can affect the frequency you will have to paint your roof, since frequent repainting and painting are as expensive as an inconvenience.

The following article will walk you through the process of painting your roof step-by-step, providing suggestions and tips throughout the process. Let’s begin.

Step-1: Roof Inspection

Before you begin any type of interior or exterior painting of the roof, whether DIY or professional first, it is important to assess the state that the roof is in. Doing the work without taking the time to thoroughly examine the roof may delay the process, and possibly causing expensive repairs and repainting. The first step is to hire a professional to inspect the roof from inside out.

Interior Inspection:

In order to obtain the full details of any damage, we suggest taking a look at both the outside of the building and its roof from inside, going into the attic and examining for damage from water. This includes any streaks, stains or dark spots, as well as mildew and mould. When the damage has been identified the professional surveyor can inspect the area and determine the severity of the damage. He will recommend reliable and experienced roofers to help.

Exterior Inspection:

When inspecting the roof’s exterior check for damaged shingles, blisters and growth of mould or algae. To prevent fungal growth we suggest zinc or lead control strips. After examining the shingles, then move to any metal roof components and inspect for the presence of rust.

To get rid of rust, apply a primer coat and paint for metal using wire wool. In general, ensure there aren’t any broken or loose parts near any chimneys, pipes, or vents. For chimneys that are damaged or have joints make use of a soft caulk or mortar to seal the affected area. Also, make sure that all roof support materials, timbers scaffolding, and harnesses show signs of termites or other insects.

Step-2: Roof Cleaning and Sterilising

After the inspection is completed and the damage has been repaired then the next thing to do is to clean the roof of dust, leaves and mould. Doing this can result in a shoddy painting job that will allow mould to spread out under the new paint. A clean and well-prepared roof surface ensures durability as well as superior adhesion and paint long-term durability.

The first step to clean will be contingent on the condition of the roof. In the case of a roof that is brand new and well-constructed it is recommended to wash thoroughly with pressure washers will typically suffice. For areas that are more worn it is recommended to wash them with a biocidal solution for a night. and disinfectant spraying will eliminate any fungal growth and cause erosion. A file can be used to clean the dirt that has built up on roof joint.

Step- 3: Sealant Application

Following that, you need applying sealant. This is done to protect roofs against extreme weather, UV, and other outdoor elements. Furthermore, roof tiles are prone to take in more paint than surfaces or tiles also. Professional painters or builders use sealing agents to gain the following advantages:

UV Protection: Without reflective technology, roofing shingles are a lot affected by UV rays that cause deterioration and damage. Roof coating or sealing with reflective elastomeric protects roofing from ultraviolet.

Roof sealants also work as fire-retardants. This is especially true when paired with the metal roof.

Reduced cost of cooling and heating Most of the time roofing sealants can reduce the escape of cold and warm air and also reducing cooling costs with cooling sealants.

Waterproof The rubber (elastomeric) as well as silicone roof sealants having moderate permeability are widely employed to guard against water growth.

Step-4: Right Roof Coating Selection

There’s a distinct distinction between coating and painting. Most of the time paint on the roof or surface just imply an aesthetic enhancement or enhancement. Coating however, in contrast enhances surface performance as well as colour retention and endurance. So, selecting the best roofing coating is vital.

Roof coatings are stronger and specifically designed to shield the roof’s surface from exposure to UV radiation extreme weather, rapid changes in temperature fluctuations and other external elements. The right coating can improve the durability of your roof. There are generally four kinds of roofing materials: acrylic silicone asphalt, polyurethane, and asphalt.

Acrylic coatings

Acrylic coatings contain solvents., emulsions that are used to cover a variety of kinds of roofing. Acrylic coatings are highly adaptable and resistant to environmental elements. However, the downside is the fact that it is available in only a few colors.

Silicone coatings

Silicone coatings are extremely thick and extremely elastic, which means they offer excellent adhesion and resistance to oxidation. Contrary to acrylic coatings, silicone roof coatings come in a wide range of colors and have reflective properties that shield against UV radiation. The high adhesion as well as the color selection make them a preferred option for roofing.

Asphalt coatings

Asphalt coatings are solvent-based emulsified materials, but they have a higher level of water-proofing. They can be fluid or cold-processed. Regarding the color asphalt coatings tend to be in the form of black, or even aluminized since they are commonly applied to other roofing materials made of asphalt.

Coatings made of polyurethane

Like asphalt coatings polyurethane coatings also have solvent-based coatings that have the highest resistance to abrasion as well as pedestrian traffic. Polyurethane coatings come with two kinds of aliphatic and aromatic, and both are utilized to prepare commercial roofs.

Step-5: Preferred Roof Painting Method Selection

After the coating phase is and sorted then the next thing to do is to choose the best method of painting. Dulux certified painters can assist in choosing the best roofing painting technique from the options below, or suggest a more specific one based on the specific project.

Paint Brush Method

One of the oldest and affordable techniques is the paintbrush technique. Utilizing a variety of brushes, you can get an even coat with the smallest quantity of paint.

Roller Paint Method

The roller-paint technique is an excellent alternative to using a paintbrush that requires lesser time and equipment. The method, however, is messy and must have the assistance of a trained professional to ensure an even application without splashes. If you decide to try the method of roller painting it is recommended that different sizes of rollers be used on different types of surfaces.

Spray Paint Method

The spray paint technique is typically used for commercial painting where various tools such as airless sprayers or high-pressure paint sprayers are used. This method is efficient in time since it covers vast areas in a short time.

Step-6: Roof Paint Application

The final stage of roofing is to ensure the correct painting. Below, we’ll go over the different paint types and the best way to apply to the specific surface. The two most commonly used kinds of roof paints are oil-based and water-based. Roof paints that are water-based work best with tiles or shingle roofs. Oil-based pigments are suitable for metallic or iron roofing.

Today, many paints contain the ability to use thermal additives and weather-proofing technology to provide additional protection, in addition to the coating and sealing.
