The Best Roof Coverings for Roof Lanterns: A Comprehensive Guide
Roof lanterns are a stylish and practical way to bring natural light into your home, transforming dark spaces into bright, airy areas. However, selecting the right roof covering to complement and support your roof lantern is crucial. This blog post explores different types of roof coverings, including EPDM, Felt, GRP, Single Ply, and Asphalt, with a focus on their suitability for roof lanterns, especially when considering complex details and long-term performance.
1. EPDM (Ethylene Propylene Diene Monomer)
Overview
EPDM is a synthetic rubber membrane widely used for flat roofs. Known for its durability, flexibility, and resistance to extreme weather conditions, EPDM is a popular choice for many homeowners.
Benefits for Roof Lanterns
- Flexibility: EPDM can accommodate the structural changes required to install roof lanterns without compromising the integrity of the roof.
- Durability: This material is long-lasting and can withstand temperature fluctuations, UV exposure, and weathering, ensuring the roof lantern's installation remains secure.
- Waterproofing: EPDM provides excellent waterproofing, protecting the interior of your home from leaks and water damage around the roof lantern.
- Ease of Detailing: EPDM can be easily cut and shaped to fit complex roof lantern details, such as corners and edges.
Considerations
- Installation: Requires professional installation to ensure seams and joints are properly sealed.
- Aesthetics: Limited color options, usually black or dark gray.
2. Felt
Overview
Felt roofing, traditionally used on sheds and small buildings, is an economical option that offers decent protection against the elements.
Benefits for Roof Lanterns
- Cost-Effective: Felt is one of the most affordable roofing materials available, making it a budget-friendly option.
- Ease of Installation: Felt is relatively easy to install, which can simplify the process of adding a roof lantern.
- Versatility: It can be applied to various roof shapes and sizes, accommodating different designs for roof lanterns.
Considerations
- Longevity: Felt tends to have a shorter lifespan compared to other materials and may require more frequent maintenance.
- Water Resistance: Although felt provides basic waterproofing, it is not as effective as other materials in preventing leaks, especially around roof lantern installations.
- Complex Details: Detailing around roof lanterns can be challenging with felt due to its less flexible nature.
3. GRP (Glass Reinforced Plastic)
Overview
GRP, also known as fiberglass roofing, is a strong, lightweight material that offers excellent durability and resistance to various weather conditions.
Benefits for Roof Lanterns
- Strength: GRP is highly durable and can support the structural load of roof lanterns without risk of damage.
- Seamless Finish: GRP roofing provides a seamless, watertight finish, reducing the likelihood of leaks around the roof lantern.
- Low Maintenance: This material requires minimal maintenance, ensuring the roof lantern remains secure over time.
- Complex Details: GRP can be molded to fit intricate roof lantern details, providing a neat and effective seal.
Considerations
- Installation: Professional installation is recommended to achieve a proper finish.
- Cost: GRP can be more expensive than other options, but its durability and low maintenance justify the investment.
4. Single Ply
Overview
Single Ply roofing membranes, typically made from synthetic materials like PVC or TPO, are known for their flexibility, durability, and ease of installation.
Benefits for Roof Lanterns
- Flexibility: Single Ply membranes can easily adapt to the structural modifications needed for roof lantern installations.
- Durability: These membranes offer excellent resistance to UV radiation, chemicals, and punctures, ensuring long-term protection.
- Energy Efficiency: Some Single Ply materials reflect sunlight, contributing to improved energy efficiency and reduced cooling costs.
- Complex Details: Single Ply membranes can be heat-welded, creating strong, watertight seals around complex roof lantern details.
Considerations
- Installation: Requires skilled professionals to ensure proper welding and sealing.
- Cost: Higher initial cost compared to felt, but offers better performance and longevity.
5. Asphalt
Overview
Asphalt roofing is a traditional and widely used material, particularly for flat and low-slope roofs. It is known for its durability and affordability.
Benefits for Roof Lanterns
- Durability: Asphalt is highly durable and can withstand various weather conditions, providing long-lasting protection.
- Cost-Effective: Asphalt is relatively affordable, making it a practical choice for many homeowners.
- Ease of Repair: Any damage to an asphalt roof can be easily repaired, ensuring the roof lantern installation remains secure.
Considerations
- Weight: Asphalt roofing can be heavy, so it's essential to ensure the roof structure can support both the material and the roof lantern.
- Complex Details: Asphalt may require additional sealing and flashing to properly manage complex roof lantern details and prevent leaks.
- Aesthetics: Asphalt might not offer the sleek, modern look some homeowners desire for their roof lantern installations.
Conclusion
Choosing the right roof covering for your roof lantern is crucial to ensure the installation's durability, safety, and aesthetic appeal. For the best performance, EPDM and GRP stand out due to their flexibility, durability, and excellent waterproofing properties, especially for complex details. Single Ply membranes also offer great benefits, including energy efficiency and ease of handling intricate designs. Felt and Asphalt provide cost-effective options but come with trade-offs in longevity and detailing capabilities. By carefully considering these materials, you can create a beautiful and functional space that maximizes natural light and enhances your home's
