When it comes to roofing options, one of the most common types of roofs you’ll encounter is the flat roof design. Flat roofs have become increasingly popular due to their sleek and modern appearance, as well as their affordability and ease of installation. However, choosing the right type of shingles for flat roofs can be a critical decision that requires careful consideration. In this article, we will explore the suitability of specific shingles for flat roofs, providing you with valuable insights to help you make an informed decision.
Understanding the Requirements of Flat Roofs
Before delving into specific shingle options, it is crucial to understand the key requirements of a flat roof. Unlike sloped roofs, flat roofs have a minimal pitch or no pitch at all. This design choice raises concerns regarding water drainage, as water tends to accumulate on flat surfaces. Therefore, the primary consideration for shingles on flat roofs should be their ability to provide effective waterproofing and prevent water pooling.
Shingle Options for Flat Roofs
When it comes to shingles suitable for flat roofs, there are two main types worth considering: built-up roofing (BUR) and modified bitumen roofs.
1. Built-Up Roofing (BUR)
Built-up roofing is a traditional and time-tested option for flat roofs, characterized by multiple layers of felt or fiberglass mats saturated with asphalt. These layers are then topped with a protective coating of gravel or reflective granules. BUR offers excellent waterproofing capabilities and durability, making it a popular choice for commercial and residential flat roofs.
2. Modified Bitumen Shingles
Modified bitumen shingles are another viable option for flat roofs. These shingles consist of a combination of asphalt and various synthetic materials, resulting in enhanced flexibility, durability, and resistance to extreme weather conditions. Modified bitumen shingles are available in various styles, including smooth and granulated, offering versatility in terms of aesthetics.
Factors to Consider
When choosing shingles for flat roofs, several factors should be taken into account:
- Waterproofing: Flat roofs are prone to water pooling, making waterproofing a crucial aspect. Ensure that the shingles you choose have excellent waterproofing capabilities and are specifically designed for use on flat roofs.
- Reflectivity: Since flat roofs tend to absorb more sunlight compared to sloped roofs, it is advisable to opt for shingles with high reflectivity. Reflective shingles help in reducing the heat absorption, leading to energy savings and improved indoor comfort.
- Durability: Flat roofs are often subject to foot traffic, especially in commercial settings. Therefore, it is essential to select shingles that can withstand external impacts and maintain their integrity over time.
- Maintenance: Consider the maintenance requirements of the shingles you choose. Flat roofs may require more frequent maintenance, so selecting shingles that are easy to maintain can contribute to the overall longevity of your roof.
Consulting with Roofing Professionals
Choosing the right shingles for a flat roof can be challenging, especially if you are not familiar with the different options available. Seeking guidance from roofing professionals is highly recommended. They can assess your specific requirements, perform a thorough inspection of your roof, and suggest the most suitable shingle options based on their expertise and experience.
Specific shingles can indeed be suitable for flat roofs. The BUR system and modified bitumen shingles are popular choices due to their waterproofing capabilities, durability, and versatility. When considering shingle options for your flat roof, factors such as waterproofing, reflectivity, durability, and maintenance requirements should be given careful thought. Seeking expert advice from roofing professionals is crucial to ensure you make the best decision for your flat roof.
