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.

I had a leak late on a Saturday night. The answering service rep, Sean, got in touch with people at Guardian that night, and they called me to assess the situation. The next morning I got on Greg’s schedule to come out on Sunday. He inspected the issue, came up with a plan, and put a tarp on for a temporary cover. He gave me what I consider a fair price for the repair. The next morning, the crew was at my house before the rain started up again. Christian, Jesse, and Marco did great work and got it done before more rain started.

Everyone at this company has been amazing to work with. They have a great thing going for them. Their customer service is great, and the finished product excellent. They will be my regular roof maintenance company moving forward.

The technician, Henry V was amazing. He arrived on time having given a heads up a at 8 AM. He fixed the roof caps before the late morning clouds came. He was able to clean the very large moldy roof and gutter and mold protect them before dark. I live in the Seattle area were rain is common in November. By late afternoon it was raining heavily at times. Despite this, Henry finished a 2 day job in one day an left the site immaculate. He even made sure water never entered the house.
Lydia, the project engineer, coordinated the job perfectly. The next day I noticed that 4 windows with screens didn’t wash off. Lydia promised to send a tech to clean them.
I highly recommend Guardian Roofing

Very professional, friendly and considerate. They were the most detailed in their inspection of the roof and attic. They used advanced technology during their assessment and presentation. they explained in detail what they would do to reroof the house. Being a Platinum installer they are a little more costly.

Guardian Roofing delivers honest, quality work backed by excellent customer service.

Our roof replacement was completed in just one day at the end of October 2026. The crew also replaced the roof on our backyard barn. Throughout the entire process, the teams were professional, courteous, friendly, kind, and hardworking.

I initially had a concern about the flashing installation near our front entrance, which I thought might have been installed incorrectly based on my view from ground level. However, after seeing the installation at eye level, I was able to confirm that it had been done correctly.

What impressed me most was Guardian Roofing's responsiveness. Their customer service representatives took my concern seriously and arranged for a crew to come out the very same day to inspect the area and address my questions. That level of attention and commitment to customer satisfaction speaks volumes about the company.

Overall, I am very pleased with the workmanship, professionalism, and customer service we received. I confidently recommend Guardian Roofing to anyone in the Tacoma area looking for reliable roofing services.

I would absolutely choose Guardian Roofing again for any future roofing needs.

Inspection went well. He was knowledgeable in his job. Nothing price wise was discussed nor recommendations made, as I had to place my wife in the hospital.

Guardian Roofing did a wonderful job getting my whole roof replaced before the winter rain here in Oregon! It can be intimidating finding someone to do a big job like this when you've just moved to the area but I felt reassured every step of the way.

Unlike some of the other companies I got quotes from, Guardian never put me through high pressure sales tactics and they had a very fair price. It was clear that they'd been doing this a long time and that the shingle manufacturer trusted them enough to warranty their labor.

See you again in 30 years or so Guardian! ♥️

Ryan, Cristian, and Logan, you did great!

This is the second roofing job that Guardian has done for us and we could not be happier. Jim was a true professional. He was thorough and extremely helpful in assisting with homeowners insurance. He really went over and above. We are so grateful! As to the actual job, it is really beautiful. We were out of town at the time and when we returned, we had an amazing new roof. The clean up was excellent. The yard looked better after the job than before. Give these folks a try, you won't be disappointed. Great value and the people are amazing.

Well, we are on job #3 with Guardian! This time it was roof cleaning and moss treatment. Cannot say enough about our experience with this company. They are thorough and treat our home as if they live here. Luis was our technician this time around and in spite of torrential downpour, weather conditions that would deter a duck, these men were amazing. They even cleaned up leaves and put them in a neat little pile, which had nothing to do with the roof! Great job and worth every penny. Thank you very much!

Job #4! Damage from a falling tree tree branch.
Joe was our roof inspector/estimator. He was thorough, knowledgeable and extremely courteous. He did a complete inspection, answered every question and addressed our concerns. Just a great experience, we felt so much better after talking to him. Everything is going to be ok! These guys are great.

Their representative, Max, was very courteous and explained they could not put my chimney cap on and that I needed a hvac person.

Crew of four showed up on a very rainy day. I was surprised they didn’t postpone because I would have totally understood. Instead, they stripped the old roof and installed the new one on a detached building in our backyard. 4 hours from start to finish and the rain never gave them a break. To my knowledge, they never complained and I even saw them laughing and smiling at various times. True professionals and I would highly recommend Guardian Roofing to everybody.

Great Contractor - Needed Tile Roof repairs, a new attic fan and a replacement of a skylight. My first contact with Curran Shaw was excellent. He did a video of the roof and all the broken tiles, explaining what was wrong and whet needed fixing. So when he came in the house he was able to show me everything and he prepared the estimate and I signed up for the repairs.
The men that came out were all very professional, they cleaned up after themselves. A big Thank You to Gabriel, Ricardo and Brian. I will definitely use Guardian Roofing, Gutters & Insulation for anything that could require their services.
Thank You again, Stephanie
