Benefits of a New Roof Installation

Investing in a replacement provides more than just a leak-free home; it offers peace of mind and financial advantages.

  • Maximum Property Protection: A complete replacement removes old, compromised materials and replaces them with a modern, watertight barrier.
  • Increased Energy Efficiency: New systems often incorporate advanced underlayments and reflective materials that help regulate your home’s internal temperature.
  • Full Warranty Coverage: New installations come with manufacturer warranties that protect your investment for decades to come.
  • Improved Home Value: A new roof is one of the highest-return investments a homeowner can make when preparing for a future sale.
  • Updated Aesthetic: Choose from modern asphalt shingles or premium metal roofing to completely transform the look of your home.

Signs You Need Roof Repairs

Recognizing the early warning signs of a failing roof can save you thousands of dollars in the long run.

  • Visible Water Stains: Discoloration on your attic rafters or interior ceilings often indicates an active leak that requires immediate attention.
  • Missing or Damaged Shingles: High winds can peel back asphalt shingles, leaving the underlayment vulnerable to water penetration.
  • Granule Loss in Gutters: Finding excessive sand-like particles in your downspouts is a primary indicator that your roofing material is reaching the end of its life.
  • Damaged Flashing: Cracks or gaps around vents and chimneys are common entry points for water that require chimney sealing or specialized repairs.
  • Issues with Skylights: Condensation or dripping around roof windows often necessitates professional skylight repair to restore the seal.

Gutter & Gutter Guard Installation in Mercer Island

With the high volume of rainfall in Western Washington, a functional drainage system is your home’s first line of defense against foundation damage and basement flooding. The heavy debris from the island’s many trees can quickly clog standard systems, making gutter installation or the addition of gutter guards a vital investment. We provide custom solutions, including seamless gutters that are designed to handle the specific runoff requirements of your roofline.

Call us today to discuss your options for rain gutters and protect your landscaping and foundation.

Reasons to Upgrade Your Gutter System

A modern gutter system does more than just move water; it preserves the structural health of your entire property.

  • Foundation Protection: Quality rain gutters direct water away from your home to prevent soil erosion and basement leaks.
  • Siding Preservation: Properly functioning systems prevent water from overflowing and staining or rotting your home’s exterior siding.
  • Reduced Maintenance: Installing high-quality guards significantly reduces the frequency of dangerous climbs to clean out trapped leaves and pine needles.
  • Pest Prevention: Eliminating standing water in clogged gutters discourages mosquitoes and other pests from nesting near your roofline.
  • Ice Dam Prevention: Efficient drainage helps minimize the risk of ice dams forming along the eaves during cold snaps.

Attic Insulation & Ventilation for Mercer Island Homes

Energy efficiency starts at the top of your home. Proper attic insulation works in tandem with your roofing system to regulate temperatures and reduce utility costs. Many older homes on the island lack the necessary R-value to keep heat in during the winter and out during the summer. By optimizing your attic space, you can improve comfort and prevent common issues like attic mold or premature shingle wear caused by excessive heat buildup.

Contact us today to schedule an evaluation of your attic and start saving on your monthly energy bills.

Benefits of Improved Attic Insulation

A well-insulated attic is a key component of a high-performing and healthy home environment.

  • Lower Utility Bills: Better thermal resistance means your HVAC system doesn’t have to work as hard to maintain a consistent temperature.
  • Improved Indoor Comfort: Quality insulation prevents “hot spots” in upper levels and helps maintain a cozy atmosphere year-round.
  • Structural Longevity: Balanced attic temperatures prevent shingles from “baking” from the inside out, extending the life of your roof.
  • Better Air Quality: Sealing and insulating the attic helps prevent allergens and pollutants from migrating into your living spaces.
  • Noise Reduction: Thick insulation provides an added layer of soundproofing against outside noise and heavy rain.

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.

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
