Advantages of White Roof Coatings
Advantages of White Roof Coatings
What are the advantages of white roof coatings? White roof coatings reflect the sun's heat, lowering your building's cooling costs and extending the life of your existing roof. They also help reduce the amount of waste sent to landfills.Symptom
You might notice your building's air conditioning unit running constantly, struggling to keep the inside cool, especially on hot, sunny days. Your energy bills are high, and your roof surface feels extremely hot to the touch. You may also see signs of your roof material cracking, blistering, or breaking down sooner than expected.Problem
Dark roofs absorb most of the sun's energy, turning your roof into a giant heat radiator for your building. This makes your air conditioning system work harder, driving up your energy bills. The constant expansion and contraction from extreme temperature changes also stress your roof material, making it age faster and more prone to leaks. This means your roof will need costly repairs or a full replacement much sooner than if it were protected. Ignoring these issues leads to higher operational costs, premature roof failure, and potential disruption to your business from leaks or uncomfortable indoor temperatures.Solution
Our Conklin-trained contractors apply white roof coatings directly over your existing commercial roof. These coatings are designed to reflect a large percentage of the sun's UV rays and heat instead of absorbing them. Here's how we typically do it:- Inspection: First, a Conklin-trained contractor will inspect your roof to make sure it's a good candidate for restoration. We check for wet insulation, structural damage, and the overall condition of the existing roof membrane. If the roof is too far gone, or if there's significant water saturation in the insulation, a coating may not be the right fit.
- Preparation: We thoroughly clean the roof surface, removing all dirt, debris, and loose materials. Any necessary repairs, such as patching holes or addressing minor leaks, are completed before coating.
- Reinforcement (if needed): For some roof types or areas with more wear, we might embed a reinforcing fabric into a base coat to add strength and durability.
- Base Coat Application: One or more layers of a strong adhesive base coat are applied. This coat ensures the reflective topcoats bond properly to your existing roof.
- Top Coat Application: Finally, the bright white reflective top coats are applied. These acrylic coatings create a seamless, waterproof barrier that reflects sunlight and protects your roof from the elements.
Frequently Asked Questions
Does a white roof coating eliminate the need for future roof repairs?
No. While a white roof coating extends the life of your roof and protects it from the elements, regular maintenance is still important. Inspections can catch small issues before they become bigger problems, helping your restored roof last for many years.Can a white roof coating be applied to any type of commercial roof?
White roof coatings can be applied to many common commercial roof types, including metal, modified bitumen, EPDM, and TPO. However, suitability depends on the current condition of your roof, including its structural integrity and insulation. A thorough on-site inspection by a Conklin-trained contractor is needed to confirm if your roof is a good candidate for restoration.How much energy can I really save with a white roof coating?
The exact energy savings vary depending on factors like your building's insulation, climate, utility rates, and how well your current roof performs. However, by significantly reducing the heat absorbed by your roof, white coatings can lead to noticeable reductions in cooling costs for many building owners. Is your commercial roof showing its age, costing you too much in energy bills, or absorbing too much heat?

Frequently Asked Questions
Why does cool roofs work by reflecting sunlight matter?
Lowering energy use is not the only benefit that accrues from the use of cool roof coatings. White coatings can extend the life expectancy of many different types of commercial roofing systems simply by avoiding the high roof temperatures associated with exposure to the sun.
Why does advantages of white roof coatings matter for commercial buildings?
A dark roof absorbs the sun’s heat, while a white roof coating reflects it away.
What should building owners know about advantages of white roof coatings?
The answer to that question is that a white roof coating, or “cool” roof could potentially lower the surface temperature of your roof by up to 100°F. That’s according to the California Energy Commission, which estimates that cool roofs can trim cooling costs by 20 percent on average in the state.
How does advantages of white roof coatings affect roof performance?
A test was conducted on a sunny day with an ambient temperature of 100 degrees F. The surface of a roof with a black membrane reached a whopping 180 F, and a gravel roof reached 145 F. In comparison, a roof with white reflective roof coatings was remarkably cooler at 90 F.
