Trusted Flat Roofing
in the Pacific Northwest

Flat and low-slope roofing installation, repair, and maintenance by Squatch Roofing, built for the wet climate of Greater Seattle & the Eastside.

Flat and low-slope roofs require more than a visual inspection and a layer of new membrane. Water has nowhere to run on a flat surface, which means slope, drainage, seams, and material selection all have to work together. When they do, a flat roof is one of the most durable and serviceable systems available. When they don’t, problems compound quickly.

Squatch Roofing installs and maintains flat roofing systems built for the wet climate of Greater Seattle and the Eastside. We work with multiple membrane systems, design drainage properly from the start, and back every installation with a comprehensive workmanship guarantee.

Types of Flat Roofing Systems

Squatch Roofing installs and maintains multiple flat roofing systems. We recommend the right one based on your home’s specific slope, drainage layout, and long-term performance needs:

  • TPO (Thermoplastic Polyolefin): A single-ply membrane that reflects heat and resists UV degradation, punctures, and chemical exposure. TPO is one of the most widely used flat roofing materials for residential applications due to its durability and energy efficiency.
  • EPDM (Ethylene Propylene Diene Monomer): A rubber membrane known for its long service life and flexibility in cold temperatures. EPDM performs exceptionally well in the Pacific Northwest climate, it expands and contracts without cracking through seasonal temperature swings.
  • PVC (Polyvinyl Chloride): A strong, chemically resistant single-ply membrane with heat-welded seams that form a virtually watertight bond. PVC is a premium option offering flexibility and excellent long-term durability for low-slope roofing applications.
  • Modified Bitumen: A multi-layer asphalt-based system reinforced with polyester or fiberglass. Modified bitumen is applied in overlapping layers that create a tough, redundant water barrier, a reliable choice for homes requiring proven performance at a lower price point.

Not sure which system is right for your home? We’ll walk you through the options during your free 21-point inspection, no jargon, no pressure, just a clear recommendation based on your roof’s actual condition and your goals.

Proactive Care for Long-Lasting Flat Roofs

Flat roofs are more maintenance-sensitive than pitched systems. Catching problems early, before water has a path inside, is what separates a roof that lasts 20 years from one that fails at 10. The most common issues we address:

  • Ponding Water and Drainage: Flat roofs are prone to water pooling if drainage isn’t properly designed or maintained. Standing water accelerates membrane wear and reduces roof life. We assess drainage during every inspection and correct slope or drain issues before they cause interior damage.
  • Membrane Cracking, Blistering, or Punctures: UV exposure, foot traffic, and thermal movement can all compromise a flat roof membrane over time. We identify and repair surface failures early, before they become leaks.
  • Seam Separation and Flashing Failures: Seams, perimeter edges, and penetration flashings are the most common flat roof leak points. Routine inspection and targeted repairs at these locations prevent the majority of avoidable water intrusion.
  • Debris and Vegetation Buildup: Leaves, moss, and organic material trap moisture and block drains. Scheduled clearing and routine maintenance keeps water moving off the roof and significantly extends membrane life.

Squatch Roofing’s proactive maintenance approach means these issues are handled before they lead to an expensive repair or premature replacement. Ask about our maintenance program when you schedule your inspection.

Why Homeowners Trust Squatch for Flat Roofing

  • Skilled Flat Roof Specialists: Low-slope and flat roofing requires different techniques, materials, and drainage knowledge than pitched roofing. Our crews are trained specifically for flat systems, membrane selection, seam welding, drainage design, and long-term performance.
  • Custom Solutions for Every Structure: No two flat roofs are identical. We evaluate your home’s specific slope, drainage situation, and load requirements before recommending a system. The right material for your roof depends on those details, not a default recommendation.
  • Durable, Energy-Efficient Systems: We install flat roofing systems built to handle the Pacific Northwest’s persistent moisture and temperature swings. Reflective membrane options like TPO and PVC also help reduce cooling loads and improve overall energy performance.
  • Clean and Organized Worksites: Flat roof work often happens in close proximity to HVAC equipment, skylights, and roof access points. We protect all surrounding infrastructure, manage debris carefully, and leave the roof and surrounding area clean after every project.
  • Comprehensive Warranty and Support: Every flat roofing installation includes manufacturer material warranties and our own workmanship guarantee. If anything isn’t right after we leave, we come back and make it right.

FAQ

Frequently Asked Questions

Squatch Roofing has a knowledgeable and experienced team that can help answer a variety of questions you may have.

Are flat roofs prone to leaks?

Flat and low-slope roofs are not inherently leak-prone, but they are less forgiving of installation errors or deferred maintenance than pitched roofs. Water moves slowly on a flat surface, which means any gap in a seam, flashing, or drain can allow prolonged pooling and eventual intrusion. When properly installed and maintained, a flat roof performs reliably for 20–30 years or more depending on the membrane system.

What is ISO board insulation and why does it matter?

ISO board (polyisocyanurate) is a rigid insulation layer installed beneath the flat roof membrane to improve thermal performance and help create positive drainage slope. It helps guide water toward drains or scuppers and significantly extends the membrane’s lifespan by reducing thermal stress. We assess your home’s existing insulation setup during every inspection and recommend upgrades where they’ll make a measurable difference.

Do flat roofs require regular maintenance?

Yes, more so than pitched roofs. Drains need to stay clear, seams should be checked periodically, and any surface damage should be addressed before water finds a path in. Most flat roof failures are the result of small issues that went unaddressed. Squatch Roofing offers maintenance inspections for existing flat roofs, we document the condition, clear any drainage blockages, and flag anything that needs attention before it becomes an expensive repair.

Can Guardian repair or replace an existing flat roof?

Yes, Squatch Roofing handles both flat roof repairs and full replacements. For isolated membrane damage, seam failures, or flashing issues, targeted repair is often the right call. For roofs with widespread membrane degradation, multiple leak points, or a system that’s approaching end of life, replacement delivers better long-term value. Our inspection will tell you clearly which situation you’re in.

“Jim came by and did a very thorough inspection of the roof, both the exterior and in my attic. He did a great job explaining the results and laying out the different options available to me.
