Reliable Flat Roofing Solutions

Water has nowhere to hide on a flat roof, which makes every seam, slope, and drain critical to protecting the structure below. Low-slope systems demand precise design and expert installation to prevent leaks, reduce maintenance, and improve energy performance.

Guardian Roofing, Gutters & Insulation specializes in modern flat roofing solutions using materials like TPO, EPDM, PVC, modified bitumen, and built-up roofing. Each installation is tailored to your property, ensuring watertight performance and a long service life.

Types of Flat Roofing Systems

Low-slope roofs rely on the right materials and precise construction to keep water out and energy costs down. Guardian installs and maintains multiple flat roof systems to meet the needs of residential, commercial, and multifamily properties.

  • TPO (Thermoplastic Polyolefin): A single-ply membrane known for reflective, energy-efficient properties and heat-welded seams for watertight performance.
  • EPDM (Ethylene Propylene Diene Monomer): A durable, rubber-like membrane that resists UV rays and extreme temperatures, making it ideal for long-term, low-maintenance applications.
  • PVC (Polyvinyl Chloride): A strong, chemical-resistant membrane with heat-welded seams and excellent performance against standing water and punctures.
  • Modified Bitumen Roofing: An asphalt-based, multi-layered system reinforced with fiberglass or polyester, offering flexibility and durability for light commercial and residential use.

Guardian evaluates slope, drainage, and building structure to recommend the best system, often incorporating ISO tapered insulation to improve drainage and reduce the risk of ponding water.

Proactive Care for Long-Lasting Flat Roofs

Even the most durable flat roofing systems need consistent attention to maintain watertight performance and energy efficiency. Low-slope surfaces are more prone to drainage challenges, seam stress, and membrane wear, which makes timely inspections and maintenance essential. Guardian Roofing, Gutters & Insulation delivers expert repair and upkeep designed to extend the life of your roof and protect the structure below.

Common Issues and Our Solutions:

  • Ponding Water and Drainage Concerns: Standing water accelerates membrane wear and reduces roof life. Guardian evaluates slope and drainage, often using ISO tapered insulation systems to direct water toward drains and scuppers.
  • Membrane Cracking, Blistering, or Punctures: Heat, UV exposure, and occasional foot traffic can create damage points. Our technicians perform precise repairs and reinforce vulnerable areas for lasting performance.
  • Seam Separation and Flashing Failures: Vents, parapet walls, and skylights are common leak sources. We inspect and reseal all transitions to ensure long-term watertight protection.
  • Debris and Vegetation Buildup: Leaves and dirt trap moisture and block drains, leading to structural stress. Scheduled cleaning and inspections keep water moving and the roof performing efficiently.

Guardian’s proactive maintenance approach ensures minor issues are handled before they lead to major repairs, extending the service life of every low-slope roof.

We recently had our roof cleaned, treated, and some repairs done by Guardian Roofing. The entire process from booking an estimate to scheduling the technicians to do the work was extremely efficient! Malia, our Project Engineer, was very communicative, responsive and ensured we had all our concerns addressed before the work began. Sandro and Ferdandro, the roof technicians, did an excellent and thorough job from start to finish! We also appreciated how thoroughly they cleaned up all the debris from our house and ground at the completion of their work. We have used Guardian Roofing before and would recommend this company to anybody!

I have used Guardian for a new chimney (in 2023)and for new gutters (in 2026) and have always had such a great experience, from setting up the initial estimate appointments to the final install. Each person I have worked this has taken the time to explain each step of the process to me in easy to understand ways.I have never been pressured into using them after an inspection/estimate and they have worked with me in different options that I could afford. Once the work was done on both projects they left my roof/yard cleaner than when they arrived. They truly value their customers and my family members who have used Guardian for their roof/gutter needs have all had the same wonderful experience I have had.

Cristian and his team did a great job, They worked together well to find a logical solution(s) to the problem, and kept me informed of their discoveries and progress. There was no mess left behind, their work areas were clean. The crew found a couple of areas that contributed to the leak, fingers crossed. All in all the Guardian Team did a great job, no worries about them on site. Thank you!!
