Superior Attic Insulation Solutions in the Pacific Northwest

Every season puts your home’s energy efficiency to the test. In winter, heat rises and escapes through an under-insulated attic, driving up energy bills and straining HVAC systems. In summer, heat trapped in the attic radiates into living spaces, making your home harder to cool and less comfortable.

Guardian Roofing, Gutters & Insulation provides superior attic insulation services that transform your attic into a protective, energy-saving barrier. With professional installation of blown-in cellulose, spray foam insulation, air sealing, and ductwork insulation, we improve your home’s comfort, reduce energy costs, and extend the life of your roof by preventing heat and moisture buildup.

Comprehensive Attic Insulation Services

Guardian Roofing, Gutters & Insulation provides full-service attic insulation solutions that enhance energy efficiency, comfort, and roof protection. Each service is designed to address energy loss, moisture issues, and promote clean, long-term home health.

Blown-In Cellulose Insulation

Blown-in cellulose insulation fills gaps and hard-to-reach spaces, creating a uniform thermal barrier across the attic floor. It is eco-friendly, highly effective at controlling heat transfer, and resists mold growth and pest activity.

Spray Foam Insulation

Spray foam insulation forms a continuous, airtight seal that blocks drafts and prevents conditioned air from escaping. It also improves structural strength and resists moisture, making it ideal for attics with irregular layouts or exposed ductwork.

Batt or Fiberglass Insulation

Traditional batt or fiberglass insulation remains a cost-effective solution for open joist spaces. When professionally installed and paired with air sealing, it improves energy efficiency and helps stabilize indoor temperatures year-round.

Attic Air Sealing

Even the best insulation can underperform if air leaks are present. Our attic air sealing services close gaps, cracks, and penetrations that allow warm or cool air to escape. This boosts insulation efficiency, prevents condensation, and reduces energy costs.

Ductwork Insulation

Insulating ducts in the attic prevents heat loss, reduces condensation, and improves HVAC performance. Properly insulated and clean ductwork helps maintain consistent indoor comfort and reduce energy waste.

Guardian’s comprehensive attic insulation services work together to maximize efficiency, extend roof life, and create a healthier home environment.

Integrated Roof and Attic Protection

Attic insulation is part of a complete roofing and home efficiency system. When paired with proper ventilation using ridge vents and off-ridge vents, insulation helps control heat and moisture, which directly extends roof life and prevents seasonal damage.

Guardian Roofing, Gutters & Insulation ensures that your attic and roof work together by combining:

  • Proper insulation levels to prevent heat loss and uneven roof temperatures
  • Air sealing and duct insulation to reduce energy waste and control moisture
  • Balanced ventilation to allow fresh air to circulate, carrying away heat and humidity

This integrated approach reduces ice dams, prevents mold growth, and improves overall home comfort year-round.

Why Attic Insulation Matters

A well-insulated attic is one of the most effective ways to improve home efficiency, reduce energy costs, and protect your roof from long-term damage. When insulation is missing, damaged, or poorly installed, the home pays the price in terms of comfort, cost, and structural integrity.

Key reasons attic insulation is essential:

  • Energy Efficiency and Cost Savings – Quality insulation prevents heat loss in winter and keeps cool air inside during summer, lowering utility bills and reducing strain on HVAC systems.
  • Enhanced Indoor Comfort – Insulation helps maintain consistent indoor temperatures, eliminating cold drafts and hot spots.
  • Roof Protection and Ice Dam Prevention – Proper insulation prevents uneven roof heating that leads to ice dams, leaks, and shingle damage.
  • Moisture and Mold Control – A properly insulated and air-sealed attic resists condensation, which helps prevent mold growth and wood rot.
  • Extended Roof and Home Lifespan – By controlling heat and moisture, attic insulation supports the overall health of the roof and attic structure.

Guardian Roofing, Gutters & Insulation focuses on real, measurable benefits, helping homeowners enjoy a more comfortable, efficient, and protected home.

Comfort and Efficiency Begin Above

A properly insulated attic does more than save energy—it protects your roof, extends the life of your home, and keeps every season comfortable. By controlling heat flow and preventing moisture buildup, insulation plays a critical role in maintaining a safe and efficient home environment.

Guardian Roofing, Gutters & Insulation takes a thorough, detail-oriented approach to attic insulation, addressing air leaks, moisture risks, and energy loss at the source. With the right combination of insulation, air sealing, and duct protection, your attic becomes a quiet partner in the long-term health and comfort of your home.

Our Valued Clients

Guardian Roofing is an amazing company. I had a broken downspout I needed repaired and wanted an exact match to my previous downspout, they immediately answered my call and were so helpful. I spoke with Alicia and she was kind, understanding, well informed and was able to deal with the complexities and difficulties of my job extremely smoothly. They also are extremely good about following up, offer flexible scheduling, and send text messages as well as calls to ensure communication is at its best. After I spoke with Alicia, Emre came out quickly to give me a bid. He was extremely professional, kind and clearly very knowledgeable about gutters and roofs. After doing a thorough inspection, he put together a quote for me to take care of my broken downspout and even added in a downspout filter for free! Emre ensured I was comfortable and that I understood every part of the process, and gave me a very fair price. I highly recommend this company for your roofing and gutter needs!

Ron Otis did an excellent job representing Guardian Roofing. He arrived on time, he did a thorough (and videotaped) inspection of the roof, he provided a clear and pragmatic roofing solution that would best serve the realities of our particular structure, and finally, he gave us a clear and helpful overview of various payment options. Thank you, Ron!

Phase 2 (gutter cleaning, moss abatement, and final finishing of the chimney) is now complete. I can say that Guardian Roofing, Gutters and Insulation continued to meet or exceed my already high expectations. This company receives my tip top recommendation. Guilmar Alarcon, my last technician, continued the professional and efficient performance each person who worked on my project exhibited. A shout out to Joey Harman, who was my direct contact with Guardian. Excellent communication is one of my hallmarks of a great company. Joey kept me in the loop on who would be coming to work, when, and what they would be doing, as well as returning any emails or calls I made promptly and pleasantly. Guardian Roofing is the way to go for all your roofing, gutter, and insulation needs!

Today Gabriel Solano did above and beyond any expectations we had regarding our repairs. He's incredibly knowledgeable, reliable and respectful. Explains the process clear with pictures. Safety first is always the most important, he was tied off always. :) he spoke with my husband over the phone explaining what was taking place while hes not here. Just an overall excellent experience.

I can’t recommend Guardian Roofing, and especially Jose Luis Corona Rios and his crew, highly enough. Communication was clear from start to finish, they showed up when they said they would, and they kept me informed throughout the entire repair process. Their safety protocols were excellent and very professional, and they were consistently respectful of my property while working. They repaired my chimney crown, completed shingle repairs, and fixed flashing, and the work looks great. What I appreciated most was the photos they shared of the work in progress and the completed repairs, since everything was up very high and nearly impossible to see clearly from ground level. The whole experience was smooth and stress-free. I also want to highlight Ryan, the roofing specialist I met with initially for my quote. He had a friendly, low-pressure approach, explained everything clearly, and the photos he provided were incredibly helpful in understanding what was needed. Finally, Deimar, the project engineer, was wonderful to work with. She was attentive, kept us up to date on scheduling, and followed up promptly whenever we had questions. Everyone I interacted with at every step was genuinely friendly and professional. I highly recommend them!

Everyone from Guardian Roofing and Gutters was very helpful after a tree fell on our roof. We needed to replace the garage roof and gutters. Josh worked with our homeowners association and insurance company to help cover the costs. They were efficient and completed the work in a timely manner. It looks great and we have not had any problems. We have used them before and I would not hesitate to use them again.

PNW storm season hits hard... So I called up Guardian Roofing and talked to Deimar, who was fantastic to work with! Of course, this was during the worst PNW torrential rain storm of the century, and my roof started leaking! After talking with them, they had someone come out asap to check it, and then tarp it until they could get to it (because everyone else's roof was leaking too) .. Then they came out to start the job they found some other problems, rotting wood under shingles that were not put on properly ... so I ended up having more work done... BUT, it is done so well, and in a two day time frame, (once they started the job) from rip off, to new wood, to shingles, and proper roof venting (PLUS they fixed my overhang that birds were getting into), to clean up and haul away of all debris!!!! I will not be worrying about this roof leaking or anything for many years to come!!!! Thank you to Deimar for facilitating the job and thanks to the worker, Uriel Rico, who went above and beyond on this job! What a great worker he is, and a pleasant person to deal with. This was for a larger almost flat roof dormer on top of my house. They added in proper venting on the top ridge and at the bottom, or low end too. Job well done!
