Adding a protective coating to your rooftop is an excellent way to prevent long-term damage. However, this extra layer may not be as effective if you ignore roof surface preparation before applying it. This begs the question: How do you prep a roof for coating?

At Engel Coatings Inc., we offer flat roof coatings for New Mexico homes and businesses. Our experts utilize the highest-quality products to combat the region’s harsh climate and keep your structure safe. Check out the steps that we always follow in preparation for this project. 

The Purpose of Roof Coatings

Before diving into the preparation process, it’s important to first understand roof coatings. What are they, and is it worth investing in one?

High-quality coatings don’t eliminate the need for roof maintenance, nor do they repair existing roof damage. They do, however, offer another layer of protection against the elements.

In the Southwestern U.S., high heat and abundant sunlight can wreak havoc on roofing systems. You can opt for a custom coating with superior UV resistance to prevent fading and other forms of damage. Another coating may better suit a property in an area prone to wet conditions and ponding water. 

Experts can apply custom coatings to several types of roofing materials, including:

No matter which variety of coating you end up with, you can have peace of mind knowing that your structure will resist the elements more effectively. Your roofing system can have a longer lifespan, and you’ll minimize future repairs as part of the benefits a custom coating provides. 

Seven Ways To Prepare Your Roof for Its Coating

How do you prep a roof for coating? Any expert will tell you that you can’t jump into this project without completing a few preliminary steps. Adequate preparation is key to getting the most out of your investment. 

Below are the steps you can’t skip before applying silicone, elastomeric, acrylic, and other roof coatings. Make sure your contractor goes through each of these tasks in the lead-up to applying the coating. If they don’t, the material may not adhere properly and fail to protect your roof from damage. 

1. Assess the Structure

You wouldn’t expect a doctor to treat your illness without first examining your symptoms. Why should you make any changes to your roof without evaluating it first? Depending on the structure’s condition, experts may need to prolong their preparation phase. 

It all starts with a visual inspection. This allows contractors to detect some obvious issues with the structure, such as:

Depending on their findings, contractors might have to dig further to look for moisture damage. They may either cut out samples of the structure or perform a moisture survey to identify hidden water damage beneath the surface.

2. Test for Proper Adhesion

If you ask an expert, “How do you prep a roof for coatings?” they’ll tell you that an adhesion test is crucial. There’s no way of knowing how well the material will stick to the roof’s substrate unless you test a small piece of it.

To conduct this test, professionals clean a small patch of the roof and apply the coating. Pieces of fabric will serve as pull tabs for the test, which allow experts to try to remove the coating once it cures. If the material stays put, it passes the test, while a coating that lifts when pulled is considered a failed test. 

A preliminary test allows experts to determine how much preparation the surface requires so that the material adheres to it. If the crew skips this step, they could waste time and money applying a coating that proves to be ineffective. Protect your investment by inquiring about their adhesion testing process.  

3. Repair Roof Damage

Putting a coating over a leaky or structurally unstable roof won’t repair the existing problems. If your roof currently has leaks, damp substrates, loose flashings, or other types of damage, prioritize repairs. 

The surface must be structurally sound and without any water damage. Depending on your roof’s condition, experts may need to delay the coating by several days while they take care of repairs. This is absolutely essential before they continue with the remaining steps. 

4. Select the Right Coating

How do you prep a roof for coating? Part of it involves assessing the structure to find the right materials. You don’t want to invest in a coating that doesn’t adequately protect your roof’s surface. 

Narrow down your options with the help of qualified experts. They can review different materials and recommend ones based on the following criteria:

Think about the long-term effects of your decision. While a more expensive material might hurt your budget up front, it could offer long-lasting protection and ultimately save you money on various repairs. 

5. Power Wash the Roof

Since your roof is completely exposed to the elements, it can accumulate plenty of dirt and debris. Preparing for a roofing coating requires a thorough power washing to remove all of the built-up dirt and grime, such as: 

Imagine applying paint to a contaminated surface. The liquid may not adhere as well as it could if you started with a clean slate. 

Before crews can begin putting down primer and roof coatings, they must prepare the surface accordingly. Highly pressurized water can blast away both loose dirt and hard-to-remove grime. In some cases, experts may use a soft-bristle brush to penetrate heavy buildup before rinsing it away with power washing equipment.

6. Apply a Primer and Sealant

Roof coatings resemble paint. If you’re painting an interior or exterior surface, you typically start with a primer application to help it adhere to the wall. So, how do you prep a roof for coating?

Just like a standard painting project, the roof coating process always requires primer. This protective material hides any rust along metal roofing systems and prevents new rust formation. If you have an asphalt roofing system, primer prevents the coating from bleeding through the material. 

Primer plays a key role in making a roof coating last. But it’s not the only component. Experts should also apply a sealant, especially near fasteners and seams. 

A high-quality sealant helps waterproof the structure. Even the slightest bit of moisture intrusion can affect a roof’s structural integrity. Adding a sealant to vulnerable areas offers additional protection against water damage. 

7. Add the Coating in Stages

With the roof fully prepped, it’s now time to apply the coating either with rollers or sprayers. Experts complete this final step in multiple phases:

The ideal coating thickness may vary based on the roof’s age and condition, as well as the type of material used. For instance, a 15-year-old commercial roof with a history of damage may require more layers of coating than a two-year-old residential roof in excellent condition. 

Ask your contractor what they recommend for your structure. Bear in mind that the more coats you need, the more labor is required. This could ultimately impact the total cost of the project. 

The Benefits of Proper Roof Coating Applications

Now that you know the answer to “How do you prep a roof for coating?” you might be wondering whether the drawn-out process is really necessary. Simply put, yes, you must be thorough and follow all precautionary steps before applying a coating over your roofing system. 

Doing so allows you to reap the following benefits:

Don’t miss out on these incredible benefits. Begin researching roof coating projects and make sure you follow the tips above for preparing the surface. 

Why You Need a Trusted Contractor for Your Roof Coating Application

Property owners often have many questions regarding this type of project, including “How do you prep a roof for coating?” and “Can you perform DIY roof coatings?” If you’re considering tackling this project yourself, think again. It’s always best to leave any roof work to the professionals. 

Experts have ample experience applying roof coatings. They often work with a wide range of materials and can recommend an option that’s perfect for your structure based on its condition and your budget. Amateurs lack and training to handle each coating and may end up with one that doesn’t meet their needs. 

Safety is another key reason to enlist a professional contractor. Working on a roof can have dire consequences if you don’t take the proper precautions.

Licensed crews come with all of the necessary gear to complete the job safely. Experts usually carry insurance as well to protect property owners from any liability should an accident occur. 

Finally, hiring a professional roof coating company guarantees your desired results. Specialists don’t cut corners when preparing the surface. Their dedicated approach ensures long-lasting protection for your home or business.

If you want to update your living spaces, a fresh coat of paint may be the transformation you seek. Although interior painting seems relatively simple, it’s a process that requires a certain level of experience and expertise to complete successfully. When inexperienced homeowners paint their walls and ceilings, the surfaces sometimes develop bubbles as the paint dries.

As skilled painters in Las Cruces, NM, our team at Engel Coatings Inc. knows what causes paint to bubble. Consult our post below to learn about the most common culprits behind this issue and what you can do to prevent it. 

What Are Paint Bubbles or Blisters?

Bubbling or blistering is a common paint-related blemish. The problem occurs due to something under the painted surface that is causing the paint to lift and distort.

The blistering will look like bumps or bubbles of various sizes and may affect the entire area or a small patch. In either case, the blemish will detract from the wall’s appearance. 

Realizing that bubbles are forming under paint is frustrating. It has a significant impact on the overall quality of the paint job. Leaving the blemishes alone can worsen their appearance and cause the paint to peel or crack over time. 

Common Causes of Paint Bubbling

What causes paint to bubble? The most common reasons include the following:

Dirty Substrates

Poor surface preparation can leave dirt, oils, and grime on walls. Painting over contaminated surfaces contributes to adhesion failure. In other words, dust and other substances can affect the paint’s ability to stick to the wall completely; affected areas will form blisters as the paint dries.

Not Using Primer or Incorrect Primer Use

A quality paint job includes primer, which is a bonding agent that helps paint stick to surfaces. Painted walls are less likely to bubble or peel on properly primed walls. Not using primer on porous surfaces creates subpar adhesion, especially on unpainted porous surfaces. 

Moisture Intrusion

Water is one of the primary reasons paint sometimes forms bubbles. As moisture penetrates the layers of paint, each one will detach from the surface, leading to bubbling. 

High Humidity Levels

If moisture intrusion is a problem when painting interior and exterior surfaces, so is high humidity. When painting indoors, ensure your rooms have sufficient ventilation. Stuffy interiors can allow humidity levels to increase, which raises the chances of water intrusion and bubbling in the drying paint.

High Temperature

Temperature fluctuations can affect the drying time for paint. Yet, if the space gets too hot, it could accelerate the drying process, causing bubbles to form. The solvents and water inside the paint need enough time to evaporate so that the paint dries smoothly and sticks to the surface. 

Incompatibility

Sometimes, the proper primer application, surface preparation, and paint application aren’t enough to prevent bubbling. Some materials react poorly to certain paints. 

For instance, new wood may have natural oils that prevent proper paint adhesion. Adhesion is also a problem for glossy surfaces. 

How To Avoid Peeling or Blistering Paint

Now that you know what causes paint to bubble, you may wonder whether hiring a professional is necessary. Hiring expert painters can prevent the frustration of a low-quality paint job. However, if you want to handle the task yourself while avoiding blistering paint, follow these tips:

How To Fix Paint Blisters

Even the most prepared painters sometimes get bubbles and blisters in their work. If this happens to you, stay calm. It may be possible to fix the problem without starting over entirely.

Start the restoration process by examining the blemishes. If the bubbling doesn’t appear to go all the way down to the substrate, wait until the paint dries. Then, scrape and sand down the affected area to remove the bubbles. 

After sanding the area, ensure that it has a smooth finish. Next, apply a coat of primer, followed by a high-quality paint. 

Let’s say the blisters reach the substrate. In that case, you would have to eliminate the source of the moisture that’s affecting the paint job. Depending on the source of the water, you may address it by increasing ventilation in the room or repairing loose caulking that may contribute to water intrusion. 

Try to repair the bubbled wall only after removing the source of the moisture. Otherwise, the problem may occur again. Follow the previous sanding, priming, and painting steps to restore your wall’s appearance. Applying several layers of paint may be necessary to achieve your desired effect.
