Due to their practicality, flat roofs have been a popular roofing solution for business owners for many years. At Marina Bay Roofing, we provide durable flat roofing systems that take the unique needs of the local climate and commercial architecture into account.

Today let’s talk about the benefits of flat roofs for commercial buildings, as well as the most common types and maintenance tips that will keep your investment looking good for years to come.

Flat Roofs: Why Are They Ideal for Commercial Buildings?

Flat roofs are a popular option in commercial construction, particularly in busy metropolitan areas like San Francisco CA, where space, accessibility, and modern design are essential. Check out the many reasons why Greater Bay Area business owners are opting for flat roofing systems:

1. Cost-Efficiency

Flat roofs involve less material and labor compared with pitched roofs, which lowers the upfront costs. They have also have a simpler structure that makes them easier and faster to repair, which in turn lowers long-term expenses.

2. Modern Appearance

Many commercial property owners like flat roofs due to their contemporary appearance and clean lines, pairing well with the modern architectural styles found in San Francisco CA and surrounding areas.

3. Space Efficiency

Flat roofs provide more usable space that can be utilized for solar panels, rooftop gardens, HVAC unit bases, and employee break areas.

4. Easy Maintenance Access

Flat roofs make it easier and safer to perform inspections, cleaning, and minor repairs, compared with sloped or pitched roofs.

What Are the Most Popular Flat Roofing Systems in the Greater Bay Area?

The flat roof system you choose will depend on a variety of factors, such as the size of your building and usage requirements. Here’s a look at some of the most common flat roof solutions to select from:

TPO (Thermoplastic Olefin) Roofing

TPO, a highly reflective and energy-efficient roofing membrane, works well with the sunny climate here in San Francisco CA. Not only does it resist UV damage, it resists algae growth and chemical exposure. As such, TPO is a durable and low-maintenance choice.

EPDM (Ethylene Propylene Diene Monomer) Roofing

This rubber-based roofing solution, revered for its flexibility and resistance to weather extremes, performs well in the face of the Greater Bay Area’s varying temperatures. EPDM is also an eco-friendly option, as it can be recycled.

Modified Bitumen Roofing

Comprised of asphalt-based sheets reinforced with fiberglass or polyester, modified bitumen is easy to install and waterproof – invaluable for the rainy season in San Francisco CA.

Built-Up Roofing (BUR)

One of the oldest flat roofing systems around, BUR features multiple layers of bitumen and reinforcing fabrics for top-notch durability and insulation. You may want to go with this option if your building’s roof gets a lot of heavy foot traffic.

Benefits of Flat Roofs Specific to the Bay Area Climate

As you know, the Greater Bay Area has a diverse weather pattern. It can be cool and foggy in the mornings, and hotter inland in the afternoon. A properly-installed flat roof can manage the following conditions seamlessly:

  • Better Energy Efficiency: Reflective materials such as TPO can reduce heat absorption, keeping your building cooler and lowering your energy bills.
  • Wind Resistance: Strong winds and gusty conditions are no match for flat roofs on buildings near the coast.
  • Moisture Protection: Proper drainage systems and waterproof membranes keep pooling and water infiltration at bay during heavy rains.

Top Maintenance Tips To Ensure Long-Lasting Performance

While flat roofs are more accessible for routine inspections and repairs, they still have a need for regular maintenance to stay in optimal shape. Follow these maintenance tips to get the longest lifespan out of your flat roof:

Schedule Regular Inspections

Your flat roof should receive at least two inspections a year, once in fall and another in spring. Attention by a professional roofer in San Francisco can catch small problems early before they worsen and cost you more.

Clean the Roof

Leaks and damage can occur due to drain clogs by leaves, dirt, and branches. Sweep off the roof regularly to ensure proper water flow.

Check for Ponding Water

Standing water that lasts more than 48 hours requires evaluation by a professional.

Inspect Drainage Systems

Make sure your gutters, scuppers, and downspouts are not clogged, as proper drainage is essential for flat roofs, particular during the rainy season.

Check Seals and Flashings

Inspect and repair seals around vents, HVAC units, and edges to ensure the roof’s waterproofing capability.
