"Diamond Roofing changed my roof from cedar to asphalt. They did a great job, providing constant updates over several days, as we needed full plywood decking installed. They were the only quote that didn't skimp on materials, as most wanted to avoid perimeter water shield and use no-caulk pipe boots. I trust that I have a roof that will last for years to come."

"Great job from start to finish. Prompt, on the spot estimate with a good price. Great team from Forever Roofing did a quality job replacing our old asphalt roof with new roofing. We were very impressed and highly recommend Sam and his team. They're practical, professional and good to work with. They know what they're doing and get it done right the first time."

"We had A Better Roofing Co. do our roof about 8 years ago. They were excellent. They are always there for us when we have questions like: can we attach something to the roof without damaging it, etc. They have come out to study the questions and give answers. This time, during the storm and rain, a tree fell and damaged our roof some. They came out the next morning and scoped it out. Making sure that any holes would be secure and not do further water damage to the roof, etc. until they could get the tiles for our roof and come repair it. Which they did. They returned and installed and repaired the damage. It looks great. They are a company that not only stands behind their work, they don't forget previous clients!"

"We recently hired Kirkland Roofing Company to replace our entire roof, and we are extremely happy with how everything turned out. From the beginning, Joshua was very professional, responsive, and easy to communicate with. He took the time to explain the condition of our old roof, what needed to be replaced, what materials would be used, and what we could expect throughout the project. The crew showed up when they said they would and worked hard from start to finish. They removed the old roofing, inspected the decking underneath, completed the necessary repairs, and installed the new roofing system very carefully. We really appreciated that they didn?t just rush through the job. They paid attention to the flashing, vents, ridge caps, edges, and all of the smaller details that can easily get overlooked. Joshua kept us updated throughout the project and let us know what was happening each step of the way. If anything came up, he explained it clearly before moving forward. Communication"

"Three Tree Roofing are professionals with an experienced crew: David, the estimator, who gave me detailed information regarding my choices, carpenters like John who installed new fascia prior to gutters being installed, the roofing crew foreman, Victor, who was meticulous in his crew's roofing work and the office staff who made sure any of my questions or concerns were promptly addressed. I now have a house I am proud to show off. Kudos to Three Tree Roofing."

"I could not recommend this company enough. First, they were extremely responsive when I called them. The owners son came out so he could give me an estimate and answer my questions. He noticed that we had a shingle coming loose and said he would repair it. I called a few days later when I got the estimate (more on that in a moment). I happened to mention the shingle and asked to hire them to at least repair that in the meantime, only to find out that he had already been to our house on a Saturday and fixed it! He also inspected the rest of the roof just to make sure there werenâ t any other repairs that needed to be made. Mind you, not only did he not charge us for this service, but this was before we had even agreed to hire them for the full installation. Their bid was unbelievably reasonable and affordable. They showed up at 8 in the morning with at least 7 workers and finished the entire roof in one day (for reference we have a 3500 square foot house with a fairly large roof). The roof is perfect. I could not be happier with their service and would highly recommend them to anyone. In fact, not only have three other houses in my neighborhood used them, but I have told everyone I can to use them for any roof/gutter needs."

"Edgar and his crew did a beautiful job. Edgar was very responsive to all of my questions. He and his crew were timely, dependable, super hard working, cleaned up after themselves as they worked and careful of my flower gardens. Our new metal roof looks beautiful. I highly recommend Gold Roofing for your roof repair or replacement."

"ROOF4LIFE did an amazing job on our deck and fence projects. They provided ideas and suggestions that we hadn’t even considered, and delivered more than we expected. Projects were completed based on our time frame, and had all wrapped up before we expected. The carpenters they employ are outstanding, willing to listen to our needs, and over-delivered. I would not hesitate to call them for future projects."

"Our first contact was with Hal, who met us to provide an estimate. He was on-time and collected information on the shingle repair. We later decided to expand the scope of the project to include paint, and he met with us again to revise and update the estimate. He was very responsive to email and calls when questions came up. The pricing was competitive, and scheduled the work to complete by end of September, Hal stopped by again in person to drop of some paint samples. Aldo, the foreman, contacted me by phone and email to select colors and met me on site for him to review the work. The crews were able to start early, and the job was completed by mid-September. Each day (weather permitting) the crews arrived and started work consistently. Initially old failing shingles were removed, and then replaced. Each day the work area was cleaned up, leaving just some supplies next our garage. A light power wash followed by careful prep began after shingles were complete. We had some millwork done too, including improvement to a deck railing. Spray was completed quickly, without any issues. Trim took longer as the team was careful. The few small spills were corrected quickly. The crews also replaced/repaired vent louvers damaged by the power wash. I prepared a short punch list of questions and issues for the foreman, which were all completely addressed. We are extremely pleased with the work, and would recommend Rain City to others for siding and exterior painting. It was also very easy to work with all the folks at Rain City--they always responded quickly to any questions on site, by phone or email."

FAQs for natural slate roofing repair projects in Shoreline, WA

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
