Read below for 7 reasons why you should not install shingles on a low-sloped roof, and a recent roof repair success story from Asphalt Shingles to Modified Bitumen
When it comes to roofing, the slope of your roof is a crucial factor in choosing the right materials. While asphalt shingles are a popular choice for many residential roofs, they are not suitable for low-sloped areas. Here’s why you should avoid installing shingles on a low-slope roof and what alternatives to consider.
Water Drainage Issues
Low-sloped roofs do not allow water to drain as quickly as steeper roofs. This slow drainage can cause water to pool or remain on the surface longer, increasing the risk of water seeping through the shingles and causing leaks. Proper drainage is essential to prevent water damage and extend the lifespan of your roof.
Wind-Driven Rain
In low-sloped areas, shingles are more exposed to wind-driven rain. This type of rain can force water under the shingles, leading to potential leaks and water damage inside your home. Without the natural aid of a steep slope to shed water quickly, low-sloped roofs are more vulnerable in heavy rain and storm conditions.
In colder climates, low-sloped roofs are more prone to ice dam formation. Ice dams occur when melting snow refreezes at the eaves, causing water to back up under the shingles and into the roof structure. This backup can lead to significant water damage and expensive repairs.
Shingle Overlap
On low-sloped roofs, the overlap between shingles may not be sufficient to prevent water from penetrating, especially during heavy rainfall or when water is pooled. The inadequate overlap can compromise the roof’s ability to protect against water infiltration.
Reduced Gravity Assistance
Steeper slopes rely on gravity to help shed water quickly. Low-sloped roofs do not have this advantage, making it easier for water to penetrate any gaps or weaknesses in the roofing material. Gravity plays a significant role in keeping your roof dry and leak-free.
Improper Installation
Shingles are generally designed for steeper slopes. If not installed correctly on a low-slope roof, they may not provide adequate protection against water infiltration. Improper installation can lead to gaps, overlaps, and other issues that make your roof vulnerable to leaks.
Debris Accumulation
Low-sloped roofs are more likely to accumulate debris such as leaves, branches, and dirt. This debris can trap moisture and prevent proper drainage, leading to an increased risk of leaks. Regular maintenance and cleaning are essential to keep your roof in good condition.
A Better Solution: Modified Bitumen
Given these challenges, it’s clear that asphalt shingles are not the best choice for low-sloped roofs. Instead, consider using modified bitumen, a material specifically designed for low-sloped roofs. Modified bitumen provides superior protection against water infiltration and is more durable in various weather conditions.
Customer Success Story in Plano Texas
Recently, a customer reached out to us with frequent leaks in their low-sloped roof area. The prior roofer had installed asphalt shingles, which were not suitable for the low slope. To prevent future leaks and repairs, we replaced the asphalt shingles with modified bitumen. This upgrade not only stopped the leaks but also ensured the roof is now durable and leak-free for the future.
Conclusion
When it comes to roofing, choosing the right materials for your roof’s slope is essential to prevent leaks and extend the lifespan of your roof. Avoid installing shingles on low-sloped roofs and opt for materials like modified bitumen that are designed for such conditions.
