- PVC (Polyvinyl Chloride): Acrylic coatings are compatible with PVC roofing materials.
These coatings offer versatility and can enhance the performance and longevity of different types of roofing systems.
Acrylic coatings are the best choice:
When choosing a roof coating, your decision may depend on various factors, and rubber roof coatings can be a suitable option in specific scenarios. Here are considerations for choosing rubber roof coatings:
Limited Budget: If you have budget constraints, rubber roof coatings can be a cost-effective solution for extending the life of your roof.
Minimal Water Accumulation: If your roof does not face significant issues with water accumulation, rubber roof coatings can provide effective protection against other elements.
Metal Roof with Minimal Rust: Rubber roof coatings are particularly well-suited for metal roofs with little or minimal rust. They can be applied over mildly rusty surfaces.
Fewer Paint Coats: Unlike some other coatings, rubber roof coatings may require fewer paint coats for effective application.
It’s essential to assess your specific roofing conditions and requirements before choosing a coating type. If your metal roof has minimal rust and you’re working within a limited budget, a rubber roof coating could offer a viable solution for preserving and protecting your roofing system.
SEBS Roof Coatings
Styrene Ethylbutlyene Styrene (SEBS) roof coatings are specially formulated for use on metal roofs, offering a range of benefits tailored to this roofing material:
Reflectivity: SEBS coatings feature a highly reflective surface that helps maintain comfortable temperatures inside buildings by deflecting sunlight. This reflective property also provides maximum protection against ultraviolet (UV) rays.
Waterproofing: SEBS roof coatings are known for their waterproofing capabilities, helping to create a watertight barrier and protect the underlying structure.
Conformity to Building Movement: These coatings are designed to conform to building movements, accommodating any expansions or contractions without compromising the integrity of the roof.
High Tensile Strength: SEBS coatings possess high tensile strength, allowing them to withstand roof traffic and other stresses, contributing to enhanced durability.
Antioxidants and Light Stabilizers: The inclusion of antioxidants and light stabilizers in SEBS formulations helps prolong the lifespan of the roof coating by providing additional protection against environmental factors.
Prevention of Corrosion: SEBS coatings are particularly suitable for application on rusty metal roofs, as they help prevent further corrosion and deterioration.
Cold Climate Application: SEBS coatings are recommended for metal roofs in cold climates. However, it’s important to note that application should not take place in freezing temperatures.
If you have a metal roof, especially one with rust-related concerns, and are located in a cold climate (above freezing), SEBS roof coatings could be the optimal choice for addressing your specific roofing needs.
Facts About Roof Coating Application
Coatings alone are not a remedy for a leaky roof. While elastomeric roof coatings can cover small cracks and seams, they should not be viewed as an alternative to repairing a leaky roof. If your roof exhibits signs of deterioration, has leaks, or serious issues, it is essential to enlist the services of a roofing repair company to address and rectify the problems.
A roof coating may offer temporary relief but won’t resolve underlying issues. Before applying a coating, the existing roofing system should be repaired using compatible materials. Conducting a comprehensive roof inspection is crucial to identify visible signs of problems and address their root causes.
A leaky roof can lead to significant structural damage if neglected. Therefore, it is imperative to repair leaks and other damages with materials that match the existing roofing system, ensuring complete watertightness. Once the roof is deemed to be in optimal condition, applying for a No Dollar Limit (NDL) warranty for up to twenty years can provide long-term assurance for your investment in roof coating.
Moisture trapped beneath a coating can compromise its effectiveness. During a roof inspection, conducting a moisture scan is vital to verify the roof’s dryness. If moisture is detected, core cuts may be necessary to assess the extent of the damage. All moist and wet materials should be replaced before applying a roof coating.
Not all cleansers are suitable for every roofing material, so it’s crucial to consult with a roofing expert to determine the best option for your specific roofing material. Thoroughly cleaning the roof is essential before coating application, as any dirt, dust, or debris beneath the coating can damage its performance and reduce its lifespan. While a power wash is effective, additional scrubbing with an appropriate cleanser may be necessary, especially for roofs that haven’t been cleaned recently or have accumulated heavy soiling.
Types of Elastomeric Roof Coatings
Metal Roof Coatings
Before applying a coating, a metal roof must be in good repair to safeguard workers during the application process and ensure the coating’s optimal effectiveness.
For mildly rusted roofs, it is advisable to apply acrylics and silicones before proceeding with the coating. In the case of SEBS coatings, they can be applied without prior treatment for rust unless the roof exhibits severe rusting.
It’s important to note that fiberglass skylights present potential hazards for workers. To mitigate risks, ensure that the skylight is not painted the same color as the roof, reducing the likelihood of accidents in the future.
TPO Roof Coatings
Due to the low surface energy of TPO membranes, achieving proper adhesion of roof coatings to the surface can be challenging without prior treatment.
For long-term durability of your roof coating, it is recommended to sand down the TPO surface. Additionally, applying a suitable primer before the roof coating is essential to enhance adhesion.
Asphalt and Modified Bitumen Roof Coatings
Before applying roof coating to an asphalt or modified bitumen roof, special care is required.
For new bitumen and asphalt roofs, it is crucial to allow a minimum of ninety days for aging to let excess oil dry off before applying primer and/or roof coating.
In the case of asphalt or bitumen roofs older than ninety days, while they may not have as much retained oil as new roofs, there is still some present. Therefore, it is recommended to apply a stain blocker before coating to prevent the oil from staining the roof coating.
PVC Roof Coatings
Coating a new PVC roof can be challenging due to the natural rigidity of PVC. If your roof is made from this material, it is advisable to allow the PVC to age before applying either a silicone or acrylic coating.
EPDM Roof Coatings
EPDM roofs are highly durable and suitable for climates with severe inclement weather. However, they are not very compatible with solvents commonly used in roof coatings, as these solvents can cause the EPDM to swell. While coating an EPDM roof is still possible, it requires careful selection of solvents. It is recommended to consult with a roof coatings installer for assistance in choosing an appropriate solvent.
