Factors to Be Considered Before Coating the Flat Roof

Types of Elastomeric Roof Coatings

An elastomeric sealant provides three different choices for different roofs and materials.

  1. Acrylic Elastomeric Roof Coating/ Water Based Coating 

If you have a slanted sloped roof, the acrylic coating is suitable.  

Acrylic coating provides better insulation and is good at reflecting the heat and UV. Plywood roofs suit acrylic coating better than other types. It’s considered cheaper and required in higher amounts to compensate for the evaporated coat.

  1. Silicone Coating (flat roof paint)

Another option for the elastomeric coating is silicon coating, the best flat roof coating for flat roof surfaces. It’s a resin-based coating that keeps the surface free from ponding water. Silicone coating is considered the best because of its 2X higher resistivity feature for roof surfaces. 

Keep in mind that they are costly, but better to opt to get durable and long-lasting results and safety. If you consider Acrylic vs silicone for flat roofs, silicon is best for roof coating. The best roof coating for a metal roof is the one that can bear harsh conditions as metals are heat conductors.

  1. Urethane Coating

These polymeric coatings cost too much but possess unbelievable resistance to most harsh conditions. For a rubber roof (EPDM), polyurethane coating suits better. The only thing you need to remember is they are not good at holding the water. 

What other coatings lack waterproofing? Any guesses?

The fibered aluminum roof coating is the one that also lacks waterproofing properties.


Select the elastomeric coating type that ensures durability and effectiveness.

Resistant To Harsh Condition 

If you want to keep your roof safe from harsh environmental conditions, go for a coating that resists these conditions.

flat roof coating

Poor quality coating can’t resist these changes, and soon you will be left with a damaged roof surface. The best coat resists the high-temperature fluctuation between -40° C – 160° C and above.

Lowering the temperature

Your roof suffers a lot of harsh rays, UV, and extreme sunlight in summers, all of which make them wear and tear. To avoid your roof coat must be better, not only by reflecting them, but also to reduce the roof temperature. 

Suitability factor

Sometimes purchasing a costly coat won’t help you get the job. The problem isn’t the coating, the suitability factor that doesn’t match your flat roof. Try to purchase the one that fits your roof surface.


What does the roof coating do? It simply contracts and expands. So, what if the roof coating isn’t flexible at all? It’s just a waste of money. Look for the flexibility factor to ensure better roof coating.

What Quantity to Be Purchased

The question arises, how much coating for your flat roof needs to be purchased? It’s simple! It depends on the surface area of your roof. A small roof like the RV would require 200-300 square feet, while the large surfaced roofs like residential ones require up to gallons. So, be sure what amount is needed, to avoid overspending and wastage of time.

Heat Protection Capacity

We all know that the best roof coating will protect your inner area from heat. But wait! How much will be the protection capacity for the best coat?

You may find the roof coatings with up to 92% of heat protection, making them a better option to opt for if applicable to the surface.

Coating Color Selection 

It’s not that much of a concern but protecting your roof by enhancing its beauty makes sense. We recommend selecting a color that suits the rest of the home color. Elastomeric coating is usually white with an advanced reflectivity factor. If you opt for these coats in cold areas, go with a gray shade.

Number of Coating Required

A more concentrated elastomeric coating will be required for only one coat, while a dilute coat in three coats. Keeping the concentration, apply the desired coats to keep your flat roof safe and long-lasting.

Budget and Costing 

Well, costing and budgeting are one of the prime and most common concerns. Buyer should specify their budget in terms of the durability they require.

A less costly item will deteriorate quickly, while high quality, expensive coating will last longer than expected.

Acrylic ones are cheaper and less reliable than silicone, better, and costly. Select the one that is suitable to your budget and durability requirements.

Water-repelling feature

A water repellent coating is required to keep the roof safe from rainwater. Select the one that fulfills the criteria and maintains the flat roof free from water-related issues. If you need a moisture-resistant coating, consider the factor of perm.

Adhesive Nature of Coating 

To coat a flat roof, you may require a coat to remain in contact with the roof surface. What if you get a poor adhesion coating? It will be a waste of your money, time, and energy.

spray roof coating

So, look for the adhesion capacity of the coat before opting. You must choose the one with better peel adhesion so that it can withstand any harsh environmental conditions. A better adhesion adds to the durability and effectiveness of the coating.

Tensile Strength 

Another feature to check out is the tensile strength of your coating. Do you know what tensile strength is? The material can support a load without getting damaged when it’s stretched, divided by the cross-sectional area of the material. 

As you know, with time, the coat loses its tensile strength. It’s better to opt for a coat with the good tensile strength to stand longer and more effectively. 

Standard tensile strength

Opt for 400 ASTM to 412 ASTM Standard tensile strength and permeability of about 3.5 ASTM to make the coat run longer and better.

Eco friendly

To opt for the best roof coating, consider the eco-friendly nature of the coat. It must not be a VOC toxin releasing. Otherwise, it won’t be compatible with the environment.
