Best Flat Roofing Material options for Durability

Marketing Tri-State • July 22, 2025

Flat roofs, while cost-effective, can be prone to leaks and damage if not properly maintained. Did you know that 33% of homeowners replace their roofs due to leaks? Choosing the right flat roofing material is crucial to ensure your roof withstands the test of time and the elements. Let's explore some solid, durable choices for your flat roof installation, and discover how to make an informed decision.

EPDM Rubber Roofing

EPDM is one of the most trusted materials for flat roof installation. It's made from synthetic rubber, providing a tough, flexible, and waterproof barrier for your building. EPDM has been in use for over 50 years, proving its reliability across various climates.

Here are some key benefits of EPDM:

  • UV resistant
  • Low maintenance
  • Easy to install
  • Highly durable
  • Cost-effective

If you're seeking a material that stands the test of time, EPDM fits the bill. With its large sheets and seamless installation, it helps avoid leaks. Many homeowners and business owners choose EPDM for its ability to handle extreme temperatures, from freezing winters to scorching summers.

This roofing material is also resistant to ozone, a major cause of roof degradation. It's available in both black and white, providing options based on energy needs. The black version absorbs heat, while the white version reflects sunlight, making it perfect for reducing cooling costs.

EPDM's durability is second to none, as it resists punctures and tears. It's one of the most reliable options if you're looking for a durable roofing option that doesn't require frequent repairs.

TPO Roofing

TPO has quickly become a top contender for energy-efficient roofing materials. It's made from a blend of polypropylene and ethylene-propylene rubber, offering excellent heat reflectivity and UV resistance. This material is known for keeping the interior of your building cooler, especially during the hot summer months.

Benefits of TPO include:

  • Reflects heat
  • Energy-efficient
  • Mildew resistant
  • Fire resistant
  • Lightweight

TPO stands out for its flexibility and durability, making it a great choice for buildings that experience high foot traffic. The material is resistant to algae and dirt, meaning your roof will stay clean and visually appealing for longer periods. This makes it perfect for both residential and commercial buildings.

Energy savings add up with TPO. This roofing material reflects UV rays, lowering the building's overall temperature and reducing the need for air conditioning. TPO's resistance to punctures and tears adds to its longevity, making it an excellent choice for durable roofing options.

Installation is easy and fast, making it a cost-effective flat roof option. It's available in various thicknesses to suit different needs, adding to its versatility.

PVC Roofing

If you're focused on long-term durability, PVC is a leading option. Known for its strength and resilience, PVC offers superior performance in various weather conditions. This material is highly resistant to chemicals, oils, and other harsh elements that could damage your roof over time.

Top benefits of PVC include:

  • Fire resistant
  • Chemical resistant
  • Long lifespan
  • Easy maintenance
  • Lightweight

If you want a roof that won't back down under stress, PVC is a solid option. It resists punctures, tears, and scratches, making it highly durable and dependable for your building. The material is often used in commercial settings, but it's also growing in popularity for residential homes due to its outstanding performance.

Additionally, PVC offers excellent insulation properties, which can help save on energy bills. It has a reflective surface that keeps your building cool, adding to its energy-efficient roofing materials appeal.

This reflective feature helps minimize the impact of heat buildup, especially in sunny areas. When considering roofing material comparison, PVC shines for those who want a high-performance option that balances strength, insulation, and longevity.

Built-Up Roofing (BUR)

Built-up roofing, or BUR, is one of the oldest and most reliable flat roofing materials. It's made up of multiple layers of asphalt and felt, which are adhered together to create a strong, weather-resistant roof. BUR systems have stood the test of time and are still a popular choice today.

Advantages of BUR:

  • Excellent waterproofing
  • Long lifespan
  • Heavy-duty
  • High impact resistance
  • Minimal maintenance

BUR excels in harsh climates due to its multilayered structure. The layers of asphalt and roofing felt create a tough barrier against rain, snow, and wind. It's a perfect choice for areas with heavy precipitation or snow loads, as it can withstand the added weight.

This roofing material is ideal for large buildings, as it's highly durable and can resist foot traffic. Additionally, BUR is known for its superior waterproofing, making it one of the most trusted materials in the roofing industry. However, it may require a larger upfront investment compared to other options.

Spray Polyurethane Foam (SPF)

Spray Polyurethane Foam (SPF) offers a unique roofing solution for those looking for seamless protection and energy efficiency. SPF is applied as a liquid, then expands to form a solid, continuous layer. The foam fills every nook and cranny, providing exceptional waterproofing and insulation.

Key benefits of SPF:

  • Seamless installation
  • Excellent insulation
  • Fast application
  • Energy-efficient
  • Leak-proof

SPF offers unmatched insulation with its expanding foam, keeping your building comfortable in all seasons. It prevents heat from escaping in the winter and keeps interiors cool in the summer. This makes SPF an energy-efficient option that saves you money on heating and cooling costs.

According to Insurance Business, the cost of roof repairs and replacements in the U.S. reached almost $31 billion in 2024. This highlights how common and costly this essential home improvement project has become, especially in Tacoma. But cost isn't the only thing you should think about. Time matters just as much. Knowing how long your roof replacement will take helps you plan better. It also lets you prepare your home, set clear expectations, and avoid surprises. So, how long does it take to replace a roof in Tacoma? The timeframe isn't fixed and can change depending on your situation. Keep reading to discover how long a roof replacement really takes, what can affect it, and how to make it smooth. Average Roof Replacement Timeline For most homes, roof replacement takes about 1 to 3 days. If you have a small, single-story home with a simple roof, it could be done in just one day. Larger homes or roofs with complex shapes, multiple levels, or added features like skylights may take closer to 2 or 3 days. However, this is just on average, as other factors can extend the timeline further. Roofing Replacement Time Factors Even with a solid timeline in place, certain factors can speed up or delay your roof replacement. Some common factors include: Roofing Material Not all roofing materials install at the same pace. Asphalt shingles are quicker to install, while materials like tile or slate take longer. They may also require specialized installation techniques, which can add extra time to the project. Weather Conditions Weather plays a major role in scheduling. Roofing crews need dry, stable weather to work safely and efficiently. Rain, snow, or strong winds can cause unavoidable delays. Structural Issues Sometimes, once the old roof is off, your crew might find rotting wood or structural issues underneath. Fixing those will add time. However, it's necessary to keep your new roof solid. Permits and Inspections Depending on your location, you might need permits or a post-install inspection. It's not always a big deal, but it can cause short delays. A good contractor will plan for this ahead of time. Contractor Availability and Preparation Your roofing contractor's schedule can affect the start and progress of your project. If the crew is booked or understaffed, it might delay your roof replacement. Preparation also matters. Having all materials on-site and a clear plan helps keep things running smoothly and on time. At Tristate Roofing, we respect your time and schedule. Our team shows up on time, stays organized, and ensures all materials are ready before the work begins. Let us handle the details so your roof replacement stays on track and stress-free. Key Phases of a Roof Replacement Project Understanding the main phases of a roof replacement can help you stay prepared and avoid surprises. Here's a simple breakdown of what to expect and the timelines of each stage: Initial Inspection & Estimate (1-3 days) Your roofing project starts with a professional inspection. The contractor checks your roof's condition and gives you an estimate. This step usually takes a few days, depending on their availability. Scheduling With a Roofing Replacement Company Once you accept the estimate, your job gets added to the contractor's schedule. During busy seasons, there may be a wait before work begins. Planning & Permits (1-2 weeks) Most cities require permits for roof replacements. Your contractor should handle the paperwork, but it can take up to two weeks, depending on local regulations. Material Ordering & Delivery (1-7 days) The materials you choose affect how soon work can begin. Common shingles are usually in stock, while specialty materials may take longer to arrive. Tear-Off (0.5-1 day) The crew removes old roofing layers. This goes quickly if there's only one layer but takes longer if multiple layers need removal. Installation (1-2 days) Efficient roof installation techniques keep this stage moving fast. Skilled crews can usually complete most residential roofs within one or two days. Cleanup & Final Inspection (1 day) The crew clears all debris, nails, and leftover materials from your yard. They also check the entire roof to ensure that they have sealed and secured everything. This final step ensures that your home is protected and that the job is complete. How to Ensure an Efficient Roof Replacement Efficient roof replacement starts with proper planning and preparation. The following steps can help you avoid common delays and keep your project running smoothly: Choose the Right Contractor Hire a reputable roofing replacement company with proven experience. A reliable team ensures the work is done quickly and correctly. Prep the Site Move vehicles, clear outdoor spaces, and protect attic items. This allows the crew to work without unnecessary interruptions. Watch the Weather Schedule your project during a dry season. Poor weather conditions can delay even the best-prepared roofing job. Confirm Material Delivery Ensure all roofing materials arrive before the scheduled start date. Missing supplies can disrupt even the most efficient roof installation. Plan Ahead Maintain clear communication with your contractor. A little preparation goes a long way in avoiding last-minute surprises. Benefits of a Timely Roof Replacement Replacing your roof isn't just about fixing damage. It comes with long-term rewards, such as: Better insulation Improved curb appeal Fewer maintenance issues Strong protection Waiting too long can result in more costly repairs. A well-timed replacement gives you security, comfort, and confidence in your investment. At Tristate Roofing, we help you enjoy all the benefits of a timely roof replacement. We stick to the schedule, use top-quality materials, and ensure every step is done right. How Long Does It Take to Replace a Roof?
