When Should You Choose a Flat Roof Over a Pitched Roof?

Flat roofs have become increasingly popular for both residential and commercial properties due to their modern aesthetics, functionality, and cost-effectiveness. A flat roof system, as the name suggests, is level or has a slight slope to allow for water drainage.

While both flat and pitched roofs offer benefits, flat roofs may be the best option under certain circumstances.

Here’s when you should choose a flat roof over a pitched roof:

• You want a modern aesthetic: If you’re building a contemporary home or business, a flat roof can enhance the overall design and provide a clean, uncluttered appearance.
• You need space for utilities or rooftop access: Flat roofs allow for additional usable space. You can place HVAC units or solar panels on top, or even create a rooftop garden or patio.
• You’re looking for cost-effective installation: Generally, flat roofs are less expensive to install than pitched roofs due to their simpler design and reduced material costs. If you’re on a budget but still want a high-performing roofing system, a flat roof offers a more affordable solution.
• You want easy accessibility for maintenance: Flat roofs are easier to access than pitched roofs, making regular maintenance and inspections simpler.

How Does Water Drain From Flat Roofing Systems?

Flat roofs may seem flat, but they’re actually designed with a slight slope to help water drain off. This slope—usually 1/4” per foot—guides water toward specific drainage points like internal drains or external scuppers. These drains and scuppers direct the water away from the roof and prevent ponding, which could lead to leaks.

In addition to drains and scuppers, flat roofs often use gutters and downspouts to collect and channel runoff water. Some systems also incorporate tapered insulation beneath the roof membrane, further encouraging water to flow toward drainage points.

Does a Flat Roofing System Take Longer To Install?

To install your flat roofing system, we need to prepare the surface by removing any existing material, ensuring proper insulation, and applying a protective membrane. Each stage has its own set of requirements, which can all contribute to how long the entire process takes.

The timeline can vary extensively. Factors like roof size, material selection, and necessary repairs affect duration the most. Some materials can be installed faster, while additional reinforcements may extend the process. We can only provide a more specific estimate after an inspection and consultation.

The installation can be a fairly straightforward process compared to pitched or complex roofing systems, however. Unlike sloped roofs that require, in many cases, more intricate framing and layered shingles, flat roofing systems involve fewer materials and less structural modification.

Do You Need Planned Flat Roof Maintenance?

Planned flat roof maintenance is a scheduled service we offer that ensures your roofing system stays in good condition throughout its life. Instead of waiting for problems to develop, this approach catches issues early, reducing the risk of unexpected leaks or structural damage.

This plan is customized based on your roof’s material, age, and the demands of your building. Generally, more comprehensive maintenance is done during routine inspections. If we find any issues, we can sometimes fix them on the spot or schedule repairs at a later date if they’re extensive.

How Often Do You Need a Flat Roof Inspection?

You’ll need a flat roof inspection about twice a year, typically in the spring and fall, to catch potential issues. The goal of the inspection is to identify wear, ponding water, or membrane damage early so that major repairs aren’t necessary. If your roof experiences higher foot traffic or supports equipment like HVAC units, we recommend more frequent checks.

A history of repairs or a lack of maintenance might mean your system will benefit from more inspections, but these aren’t the only factors. The material and drainage design also play a role, since some membranes are more resistant to wear, while others may be prone to seam separation.

Compared to pitched roofs, flat systems often require more attention, even just as an extra precaution, since they don’t shed water as easily. Proper drainage should reliably protect your system, but minor damage or slight shifts in structure over time can create areas where water collects.

What Are Common Flat Roof Repairs?

You might be worried that when switching to a flat roof system, you’re voluntarily taking on more repair responsibility, but that isn’t the case. Your system will last just as long, if not longer, than pitched roofs with proper maintenance. These systems are durable, and routine inspections prevent major issues.

Flat systems do have certain characteristic repairs you should be aware of, though. One common one is fixing seam separations in membrane roofing. Over time, the adhesive or heat-welded seams between sheets of material can weaken due to expansion and contraction.

Here are a few others:

• Patching blisters and bubbles in the roofing membrane
• Sealing cracks or splits in the roof surface
• Resecuring or replacing detached flashing
• Repairing punctures or tears caused by foot traffic or debris
• Re-bonding sections of membrane with adhesion failures
