Flat Roofs: What You Need to Know
A flat roof is determined by its slope, or pitch, which is a ratio of inches rise per horizontal foot or it’s expressed in the number of degrees its surface deviates from the horizontal. On the other hand, a low-slope roof has a slope of three to 12 inches. Flat roofs are constructed around the world, more often in arid or warmer climates though commercial businesses use them across North America as well as homeowners looking at contemporary or southwestern design styles.
In North America, flat roofs are installed by placing felt paper or roofing felt made of fiber mixed with bitumen, or tar, over the roof decking to ensure it’s waterproof. Then the paper is covered with several layers of asphalt or tar, then a layer of gravel. The gravel keeps the sun’s heat and UV rays from cracking or blistering the material and extending its life, and it also acts to keep the building cooler in the summer heat. Metal flashing around the edge of the roof creates a gravel stop, preventing water from seeping underneath flat roofing material and washing away the gravel.
How to Know When Your Flat Roof Requires Repair
Flat roofs are built to last, but over time they may require repairs. Many flat roof issues stem from poor installation, inadequate maintenance, or damage—often caused when gravel is displaced from the roof membrane. Exposure to the sun and weather can cause the asphalt membrane to crack and blister, allowing water to penetrate. Once water gets through, it can soak into the roofing felt, decking, and structural components. At the first sign of a leak, it’s important to contact our roofing experts for prompt flat roof repairs to prevent moisture damage, mold growth, and wood rot.

FAQ
Flat Roof Drainage: How It Works
Flat roof drainage relies heavily on the roof’s pitch. When there’s little to no slope, drainage problems are more likely to occur.
To improve water flow and prevent pooling, there are a few effective solutions:
Slightly pitching the roof allows water to flow into a scupper box or directly into the gutters.
For roofs with minimal or no pitch, installing a tapered insulation system helps direct water runoff efficiently into the gutter system.
Proper drainage design is essential to protect your flat roof from water damage and extend its lifespan.
Flat Roof Low Spots: Causes and Solutions
Low spots are a common issue on flat roofs and typically occur when there’s inadequate drainage. These areas often collect standing water after rain, leading to pooling that can compromise the roof’s integrity over time.
What Causes Cracks in Flat Roofs?
Flat roofs are constantly exposed to direct sunlight, with no slope to deflect the heat. Over time, the intense UV rays and high temperatures can cause the asphalt layer to dry out, weaken, and eventually crack. This sun damage gradually wears down the roofing materials, leading to splits and deterioration. Once this happens, applying a new protective roof coating becomes essential to restore durability and prevent leaks.
Best Practices for Flat Roof Maintenance
Flat roofs require regular maintenance to stay effective and prevent costly damage. It’s important to inspect chimneys, vents, and other penetrations at least once a year to check for worn caulking or needed repairs. If you spot any cracks or signs of wear, contact a roofing professional promptly to seal them or apply a fresh protective coating. Regular upkeep can extend the lifespan of your flat roof and help you avoid larger issues down the road.
Top Benefits of Installing a Flat Roof
Benefits of a Flat Roof:
Long Lifespan: Depending on the materials used, flat roofs can last between 20 and 30 years.
Easy Access: Flat roofs offer safer and simpler access compared to pitched roofs.
Low Maintenance: Typically, only an annual inspection is needed to keep your flat roof in great condition.
Common Disadvantages of Flat Roofs
Some disadvantages of flat roofs include a higher risk of leaks due to potential drainage problems. Additionally, installing a flat roof can be more complex and require greater preparation compared to a traditional asphalt shingle roof.
Do You Need a Flat Roof? Key Factors to Consider
A flat roof is typically necessary when your roof’s pitch is less than 14 degrees. If your roof has a shallow slope, choosing a flat roof is often the most practical and effective solution for your home.
