Flat roofs are a common feature on both commercial and residential buildings across New Jersey. While they provide space-saving design and modern aesthetics, they also face challenges like water pooling, UV exposure, and temperature extremes. Fortunately, applying the right roof coating can enhance durability, improve energy efficiency, and extend the lifespan of your flat roof.
At Boundless Roofing & Chimney, we specialize in roof coatings for flat roofs in New Jersey. This guide explains the different types of coatings available, their benefits, and how to choose the right option for your property.
What Is a Roof Coating?
A roof coating is a protective, fluid-applied membrane installed directly over an existing roofing system. It forms a seamless, waterproof layer that:
-
Seals cracks and seams
-
Reflects sunlight and UV rays
-
Adds waterproof protection
-
Extends roof life without full replacement
-
Enhances resistance to mold, algae, and weathering
Roof coatings are ideal for flat or low-slope roofs, especially those made of EPDM, TPO, modified bitumen, or built-up roofing systems.
Benefits of Roof Coatings
Flat roofs are more prone to wear due to water retention, sun exposure, and minimal slope. A roof coating offers key benefits, including:
-
Extended Lifespan: Adds 5–15 years to your current roof
-
Energy Efficiency: Reflective coatings reduce interior heat and cooling costs
-
Leak Prevention: Coatings seal minor cracks and waterproof vulnerable areas
-
Cost Savings: Avoid premature tear-offs and costly replacements
-
Sustainability: Reduces landfill waste and is often eligible for energy rebates
1. Acrylic Roof Coatings
Best For: Dry climates and roofs with good drainage
Acrylic coatings are water-based and offer excellent UV resistance, making them great for New Jersey summers. They are typically white or light-colored, enhancing solar reflectivity and lowering indoor temperatures.
Pros:
-
Affordable
-
Easy to apply and recoat
-
UV-resistant
-
Environmentally friendly
Cons:
-
Less durable under ponding water
-
May crack in freezing temperatures
For flat roofs that drain well, acrylic is a cost-effective and reflective option.
2. Silicone Roof Coatings
Best For: Areas with frequent rain, ponding water, or high humidity
Silicone coatings are among the most durable and water-resistant on the market. They hold up well under New Jersey’s unpredictable rain and snow, offering excellent protection against ponding water.
Pros:
-
Superior waterproofing
-
UV stable and weather-resistant
-
Flexible and long-lasting (up to 20 years)
Cons:
-
Can be slippery when wet
-
Higher cost than acrylic
-
May require primer for adhesion
Silicone is a top choice for commercial or residential buildings with persistent moisture exposure.
3. Polyurethane Roof Coatings
Best For: High-traffic roofs or surfaces with mechanical stress
Polyurethane coatings are strong, impact-resistant, and highly durable. They are ideal for flat roofs with HVAC units, foot traffic, or frequent maintenance needs.
Pros:
-
High tensile strength and impact resistance
-
Resists chemical and abrasion damage
-
Good UV protection (especially in aliphatic versions)
Cons:
-
Strong odors during application
-
More expensive and labor-intensive
Polyurethane is commonly used in industrial and commercial settings that demand long-term durability.
4. Asphalt-Based Roof Coatings
Best For: Older built-up roofs (BUR) or modified bitumen roofs
Asphalt emulsions and aluminum coatings have long been used on flat roofs. Though less reflective than newer materials, they offer decent protection for aging roofs.
Pros:
-
Budget-friendly
-
Protects against moisture
-
Works well on older roofing systems
Cons:
-
Limited UV reflectivity
-
Not as energy-efficient
-
Shorter lifespan compared to silicone or polyurethane
Asphalt coatings are best for short-term protection or budget-conscious repairs.
Choosing the Right Roof Coating for Your Property
Not all coatings work for all roofing systems. Choosing the best option depends on:
-
Your current roofing material
-
Drainage performance
-
Local weather exposure
-
Roof usage (foot traffic, equipment)
-
Energy efficiency goals
At Boundless Roofing & Chimney, we perform detailed inspections and recommend the ideal roof coating based on your roof’s unique needs.
