Expert Low-Slope Roof Installation and Repair in the Tri-Cities

Flat roofs offer a modern aesthetic for homes and essential functionality for commercial buildings, but they require a completely different approach than traditional sloped roofs. Because water doesn't naturally run off a flat surface, your roof must act as a flawless, watertight barrier.

At Trudeau's Northwest Roofing And Construction, we have over 30 years of experience navigating the unique challenges of low-slope roofing. Whether you need a brand-new membrane installed or a persistent leak finally resolved, our flat roofing contractors provide honest assessments and durable solutions that stand up to the Tri-Cities climate.

Complete Flat Roof Replacement

Our Flat Roofing Solutions

Standard asphalt shingles will fail on a flat surface because water can easily seep beneath them. We use specialized membrane roofing systems designed explicitly for low-slope applications, ensuring your property remains dry and protected.

Protective Roof Coating Application Complete Flat Roof Replacement

1. Flat Roof Installation & Replacement

If your current roof has failing seams, saturated insulation, or severe blistering, we provide complete flat roof replacements. We ensure proper slope for drainage before installing premium materials:

  1. TPO (Thermoplastic Polyolefin): A highly popular, energy-efficient white membrane that reflects the harsh summer sun, lowering your cooling costs.
  2. EPDM (Rubber Roofing): A synthetic rubber membrane known for its incredible durability, flexibility, and resistance to extreme weather changes.
  3. PVC Roofing: Highly resistant to chemicals and fire, making it an excellent, long-lasting choice for various structural needs.

2. Precision Flat Roof Repair

Water travels differently on a flat roof, making leak detection tricky. Our flat roof repair specialists are experts at tracking down the true source of water intrusion. We fix:

  1. Punctures and Tears: Repairing membrane damage caused by foot traffic, fallen branches, or dropped tools.
  2. Seam Separation: Re-welding or adhering failed seams where water most commonly enters.
  3. Flashing Failures: Resealing vulnerable areas around HVAC units, skylights, parapet walls, and plumbing vents.

3. Flat Roof Maintenance & Coatings

The best way to extend the life of your flat roof is through proactive care. We offer routine maintenance to clear scuppers and internal drains. If your roof is aging but still structurally sound, we can also apply an elastomeric roof coating (like silicone). This flat roof restoration process seals minor leaks and adds a highly reflective, waterproof layer, often extending your roof's life by a decade or more without a full tear-off.

Frequently Asked Questions (FAQs)

  • This is known as "ponding water," and it is a common issue on low-slope roofs. It is usually caused by clogged drains, compressed insulation, or a slight sagging in the roof decking. If water sits for more than 48 hours, it can break down the roofing material and void your warranty. We can correct this by installing tapered insulation underneath the membrane to ensure water sheds toward the scuppers and drains.
  • Sometimes, yes. If your existing insulation is completely dry and the structural decking is sound, building codes may allow for a roof overlay. However, we must first perform core samples. If moisture is trapped beneath the old membrane, we have to perform a complete tear-off to remove the saturated materials and prevent wood rot. We offer honest assessments to determine what's best for your building.
  • In our climate, TPO roofing and PVC membranes are highly recommended due to their reflective white surfaces. They help combat the extreme summer heat, significantly reducing cooling costs inside the building. EPDM (rubber) is also excellent for its durability and flexibility during our cold winters. During your consultation, we will walk you through the most cost-effective options for your specific property.
  • On average, a professionally installed flat roofing system lasts between 15 and 25 years. The lifespan depends heavily on the materials used, the quality of the installation, and how well it is maintained. Regular inspections and clearing debris from drains are the best ways to maximize your investment.
