Roof Coatings in Washington DC Virginia Maryland

Introduction

1. What is the purpose of Elastomeric Roof Coatings?

Elastomeric roof coatings offer excellent protection for your roof, potentially extending its lifespan by up to twenty years. The most common types of elastomeric roof coatings are silicone, asphalt, polyurethane, and acrylic. These coatings are typically applied using a roller or spray method, with several gallons used per 100 square feet to ensure thorough sealing. It's important to note that elastomeric roof coatings are not the same as paint. While both are liquids, there are significant differences between them.

Elastomeric roof coatings are superior to paint for several reasons:

1. They are thicker than paint.
2. They are specifically formulated to safeguard roofs against harsh weather conditions, such as excessive water, wind, and UV light.
3. They utilize high-quality resin to provide elasticity.
4. They effectively seal minor cracks and seams in the roof.
5. Elastomeric roof coatings are environmentally friendly and can insulate the roof, helping to maintain an ideal temperature inside the building during extreme weather conditions.

2. Preparation for Roof Coating Application

Elastomeric roof coatings can be applied to various types of roofing materials. However, some preparation work is necessary to ensure optimal effectiveness. Before applying an elastomeric coating, the roof should be thoroughly cleaned. Additionally, a comprehensive inspection should be carried out to identify any existing damage. It's essential to address significant repairs before relying solely on roof coatings for protection. Concrete, masonry, gypsum, block, brick, and metal surfaces require a coat of primer before the roof coating is applied. The roof must be completely clean and dry prior to applying the primer. Consulting an expert may be necessary to determine the most suitable type of primer for the specific project and roof substrate.

3. Types of Elastomeric Roof Coatings

Silicone Roof Coatings Silicone roof coatings provide numerous advantages, including 100% waterproofing, long-lasting durability, and minimal maintenance requirements. Silicone is highly resistant to the elements, effectively preventing UV damage and maintaining waterproofing properties. With its quick curing time, silicone coatings are well-suited for application just before severe weather conditions.

Silicone roof coatings are suitable for various surfaces, including:

1. Polyurethane foam
2. EPDM
3. TPO
4. Aged PVC
5. Aged Acrylic Coatings
6. Concrete
7. Granulated Modified Bitumen Roofs
8. Asphalt Built-up Roofs (BUR)
9. Metal

Silicone coatings are the ideal choice when:

1. There are 1 to 2 layers of existing roofing
2. Water accumulation/ponding is a concern on your roof
3. Your roof has complex features that may pose challenges for traditional membrane roofing methods (such as numerous HVAC systems and lines)

Acrylic Roof Coatings Acrylic roof coatings exhibit exceptional durability and provide high UV stability. They are highly flexible, making them a preferred option for buildings located in low-temperature environments.

Acrylic roof coatings can be used on the following materials:

1. Modified bitumen
2. Smooth asphalt built-up roofs
3. EPDM
4. PVC
5. TPO

Acrylic coatings are the best choice when:

1. Budget constraints are a factor
2. Water accumulation/ponding is not a concern on your roof
3. Your metal roof has minimal or no rust

Rubber Roof Coatings Also fall into the acrylic category but differ in a few notable ways. Liquid rubber roof coatings are ideal for metal roofs, as they can be applied over mildly rusty surfaces. They require fewer coats compared to acrylic paints.

SEBS Roof Coatings Styrene Ethylbutlyene Styrene (SEBS) Coatings are specifically designed for metal roofs. These coatings offer a highly reflective surface, helping to maintain a comfortable temperature inside the building while providing maximum protection against UV rays. SEBS roof coatings are waterproof, capable of accommodating building movement, possess high tensile strength to withstand roof traffic, and are made with antioxidants and light stabilizers to prolong the lifespan of the roof. They are particularly suitable for use on rusty metal roofs, effectively preventing corrosion.

SEBS coatings are the best choice when

1. You have a metal roof, especially if it exhibits rusting
2. You have a metal roof in a cold climate (note that the coating cannot be applied in freezing temperatures)

4. Important Points about Roof Coating Application

1. Coatings alone are not a solution for a leaky roof. While elastomeric roof coatings can cover small cracks and seams, they should not be considered a substitute for repairing a leaky roof. If your roof has areas of deterioration or leaks, it is essential to hire a professional roofing repair company to address the underlying issues. A roof coating may offer temporary relief but won't fix serious problems.
2. Repair the existing roofing system before applying a coating. Before applying a roof coating, it is advisable to have your roof inspected. The inspection should not only identify visible signs of problems but also determine the root cause. If your roof has leaks or damage, it must be repaired using appropriate materials to ensure complete water tightness. Once the roof is in excellent condition, applying a roof coating can provide long-term benefits and even qualify for an NDL (No Dollar Limit) warranty of up to twenty years.
3. Moisture trapped beneath the coating can cause issues. During the roof inspection, it is crucial to conduct a moisture scan to ensure the roof is completely dry. If moisture is trapped beneath the roof coating, it will attempt to escape and potentially compromise the newly applied coating. If moisture is detected in specific areas, further investigation such as core cuts may be necessary to assess the extent of the damage. All moist and wet materials should be fully replaced before applying the roof coating.
4. Coatings require a clean surface to adhere properly. Once the roof is determined to be in good condition, thorough cleaning is necessary before applying the coating. Any dirt, dust, or debris underneath the coating can damage it and reduce its longevity. While a power wash is a viable option, it may not be sufficient for achieving the desired level of cleanliness. Using a suitable cleanser to scrub the roof is recommended. Consult a roofing expert to determine the best cleanser for your specific roofing material. In cases where the roof has not been cleaned for an extended period or has significant soiling, multiple rounds of scrubbing may be necessary before applying the roof coating.

5. Where to Apply Roof Coatings

EPDM Roof Coatings Elevate the performance and extend the lifespan of your EPDM roof with our premium silicone roof coatings. Begin by removing any chalking or residue to ensure a clean, receptive surface. Address any splits or cracks using EPDM-compatible repair materials, and consider a silicone-compatible primer for optimal bonding.

Repair damage and, if needed, use a recommended bleed primer for enhanced adhesion and to keep asphalt from bleeding through the white silicone. When applied correctly, our silicone coating offers exceptional waterproofing, safeguards against harmful UV rays, and extends the life of your roof, all while maintaining a clean and consistent look.

PVC Roof Coatings Whether your PVC roof is newly installed or showing wear, our silicone coatings can rejuvenate its appearance and protection. Thoroughly remove contaminants, then confirm primer requirements with a quick adhesion test. Once primed (if necessary) and ready, our silicone coating forms a strong, flexible shield that stands up to ponding water, tough weather conditions, and daily wear, restoring the vitality and longevity of your PVC roof.

Metal Roof Coatings Protect and beautify your metal roof with our top-tier silicone coatings. Clear away rust, debris, and any loose paint before addressing fasteners or damaged areas. For patches of rust, apply a rust-inhibiting primer to ensure the best possible outcome. A smooth, thoroughly prepped surface then allows our silicone coating to deliver exceptional weather resistance, energy-efficient reflectivity, and strong corrosion protection—giving your metal roof a robust and polished finish.

By choosing our silicone roof coatings for EPDM, TPO, Modified Bitumen, PVC, or metal roofs, you can enjoy long-lasting protection, enhanced curb appeal, and valuable energy savings. Contact Us today to learn more about how our solutions can improve and protect your roofing system.

2. Manufacturer Training and Certification: Look for contractors who are trained and certified by the manufacturer, as this ensures the highest quality of workmanship and warranty options.
3. Experience with Your Roof Type: Verify that the contractor has experience installing roof coatings on flat roofs similar to yours. Their past projects should demonstrate their expertise in handling your specific roof type.
4. Management of Staged Roofing Projects: If your project requires parallel tear-off and installation, inquire about the contractor's experience in managing staged roofing projects. This showcases their ability to handle complex projects efficiently.
5. Experience with Insurance Claims: A reputable roofing contractor should have experience working with insurance companies on damage claims. Their expertise can help streamline the claims process and ensure you receive appropriate coverage.

By selecting an experienced roofing contractor such as GoTech Roofing, you can prevent leaks and major problems while enjoying a durable roofing system that lasts for decades.

Commercial Roof Repair, Roof Restore, or Roof Replace Decision Making Factors

1. Repair – If your commercial roof inspection reveals that the majority of the roof is not saturated with moisture and there are only a few weak areas, minor roof repairs will be recommended. At GoTech Roofing we will always try to prolong the life of your existing commercial roof by performing roof repairs as a first option.
2. Restore With Roof Coating – If less than 25% of the commercial roof is saturated and the remainder of the commercial roof is nearing the end of its life, a commercial roof restoration will be the next option. Commercial roof restorations (for example silicone coating), can extend your existing commercial roof’s life by 20+ years and cost a fraction of a complete roof replacement.
3. Replace – Your roof may need to be replaced if the commercial roof inspection reveals more than 25% of the roof is saturated with moisture and there are multiple leaking areas on the roof’s surface. There comes a time in every commercial roof’s life when the roof is just too old and deteriorated, and attempting to repair it will be expensive. At this point, the roof repairs will typically only prolong full roof replacement for another 1-2 years. If the commercial roof is at this stage, it will be more cost-effective to remove and replace the entire roof.

What Should Happen During a Commercial Roof Inspection?

FAQs

1. What is silicone roof restoration, and how does it benefit my building?

Silicone roof restoration involves applying a high-performance silicone coating over an existing roof membrane—such as EPDM, TPO, Modified Bitumen, PVC, or metal—to reinforce its weatherproofing capabilities. This process offers numerous benefits, including improved water resistance (even in areas of ponding), enhanced UV protection, and potential energy savings due to increased reflectivity. By avoiding a complete roof tear-off, silicone roof restoration can also save time and labor costs.

2. How long does a silicone roof restoration typically last?

When properly applied and maintained, a silicone roof coating can last 10–20 years or more. The years a silicone roof coating will last depends primarily on how thick the silicone is sprayed on the roof. Many manufacturers provide warranties within this range, depending on variables like product selection, application thickness, and roof condition. Routine inspections and maintenance—such as cleaning and addressing minor repairs—can further extend the coating’s lifespan.

3. Do I need to remove my old roof before applying a silicone coating?

In almost all cases, there’s no need to remove a serviceable existing roof as long as it’s structurally sound and meets local code requirements. The main steps include thorough cleaning, repairing any damage, and priming where necessary to ensure strong adhesion. However, if your current roof has serious issues—such as extensive water damage or instability—you may require more extensive repairs before considering a silicone restoration.

5. How does the cost of a silicone roof restoration compare to a full roof replacement?

A silicone roof restoration is often much more cost-effective than a complete tear-off and replacement. By leaving the existing roof in place, you avoid labor-intensive demolition and disposal fees, which can significantly lower overall project expenses. In addition, a silicone coating can extend the life of your existing roof for up to 20+ years with a warranty, reducing the need for future repairs or replacements. Combined, these factors typically result in substantial upfront and long-term savings compared to a full roof replacement.
