State Farm DuPont Warehouse Receives EPDM Roof and Drainage Repairs

State Farm in DuPont selected us, Preferred Roof Service, Inc as their commercial roofing contractor of choice for their DuPont warehouse repairs. The existing roof when we arrived on site in DuPont was a gravel roofing system with leaking drains and walls. 
The warehouse had 30 commercial cast-iron bowl drains that were failing and leaking. We went through and repaired the thirty drains with EPDM membrane as well as added 750 feet of EPDM to repair the leaking walls of the warehouse.
 The commercial cast-iron bowl drains that were failing and leaking over time will lead to attic mold and rot between the layers of insulation in the interior of the warehouse. As an expert commercial roofer, we knew exactly how to repair this leakage. Our expert technicians cleaned and resealed the drains and then put a new sheet of EPDM around each drain to prevent future leakage. 

For the wall repair, we removed the coping metal and then covered it with a layer of EPDM to prevent any more leakage and then replaced the coping metal over the EPDM. We used all proper sealants to ensure in the future the EPDM would not fail in preventing leakage.

Project of the Week: Preferred Roofing Repairs Torch Down Roof for Medley Building in Lakewood, WA


As the preferred flat roofing contractor in Lakewood, we were selected to repair a torch down roofing system on the Medley Building in Lakewood, WA. The existing torch down roof was worn and damaged in places so we accessed the extent of the damaged and recommended a torch down flat roofing repair for the owners. We are highly experienced commercial roofing contractors and for this reason we knew exactly what this specific roofing system needed in repairs. We repaired this system by first repairing the areas with one layer of smooth torch down roofing material followed by one layer of torch down roofing with a granular surface.

This repair is a three layer asphalt Torch Down roofing system. A three layer torch down system consists of first, a base layer followed by a smooth torch down layer finished with a third layer of another torch down layer with a granular surface. A three layer system like this has the longest lifetime in torch down of 20 years or longer. 

Benefits to Choosing Torch Down Flat Roofing Systems: 

  1. Leak Resistant: Torch down roofing is made of rubberized asphalt material that is melted to the roof of a home using a torch. Any homeowner who is in need of strong yet flexible water resistant roofing material should go with this type of product.

  2. Heat Protectant : They can provide protection from heat. Adding extra coats of torch down applies a fire-resistant layer to the roof of a home. Torch down roofs also reflect UV rays, which helps to keep indoor temperatures down during the summer. The average lifespan for a three-layer torch down roof is two decades. Two-layer roofs tend to last around 15 years, and they rarely need to be repaired. They are free of harmful fumes. Unlike tar, torch down roofing systems do not give off any type of harmful, noxious fumes.

  3. Cheaper than metal roofing but with a comparable long lifetime of protection: These roofing materials provide a strong, leak-proof seal that will last for many years with very little maintenance or upkeep needed. The materials do not cost as much as aluminum or metal roofing supplies, and torch down roofing provides an extra layer of insulation to a home.

Preferred Roof Services Replaces Roof For Historic Chinaberry Inn In Tacoma, WA


Chinaberry Inn bed and breakfast has long been one of Tacoma's local gems as far as quality food and lodging. The old town construction provides an atmosphere that transcends time and helps clients slow down from the business of life. When we received the call to potentially be a part of renovating the historic building with a new roof we knew we had to provide a product and service that are well above standard. At Preferred Roof Services that is our mode of operation! We strive to give the best to our customers and to be the best in our industry, that is why the owners of Chinaberry Inn awarded us with the contractor for the roof replacement. We are a family owned and operated Tacoma Roofing Contractor that has been serving the roofing needs as a business for over a decade and as technicians for nearly 50 years! We are at your service for all of your commercial roofing and residential re-roof or repair needs. 

The New Roofing System We Installed 

Once we were selected at the preferred roofing company to perform the work we got right to it. We removed the existing 3 tab roofing system and installed a new Malarkey roofing system including: sheathing replacement where necessary, new synthetic underlayment (roof deck protection), starter shingles, Highlander Algae Resistant field shingles, hip and ridge shingles, new vents, pipe boots and metal flashing's. We did not cut corners or spare any expense when building the proper roofing system for our valued customer. 

Our Malarkey Roofing System

We chose to install the Malarkey Highlander AR roofing shingle on this project because we believe in the integrity of the product. Malarkey roofing shingles are manufactured in the Pacific Northwest which means we support the local economy when we install them! Their shingle construction is second to none in many areas. They have the highest concentrated AR (algae resistant) rating of all shingles. This is a big deal for our region considering the level of precipitation unleashed upon our roofs on a yearly basis.

This AR rating helps to fight against discoloration and streaking on your roof. In addition Malarkey shingles have a patented tapered nail line which eliminates what is called "water troughing." Water troughing is when the area of the shingle behind the lamination line settles and begins to collect water. It is especially prevalent on homes with roof slopes of 4:12 or less. The taper design eliminates this issue and makes Malarkey the best choice for many structures. In fact that is why many schools and government buildings in Washington State choose spec out Malarkey shingles on the majority of their projects. The quality of the shingle along with our workmanship warranty makes our product and service a safe choice for your next re-roof!

Flat Roofer Tacoma, WA | Commercial Roofer


Preferred Roof Services just completed another great flat commercial roof in Tacoma, WA. This roof is literally right in our back yard! We want to say thank you to Stratton Industries for the opportunity to work as your flat roofing contractor in Tacoma, WA. After accepting bids from many different local roofing contractors Stratton Industries found us to provide the best value and felt we were the safest choice for their project. 


The structure we roofed will be utilized as a small strip mall that will host small local businesses. It started out with a wood deck which we covered with R-Tech fan fold insulation. R-Tech fan fold provides a smooth surface that helps the membrane lie flat and also provides a small amount of R insulation value. We utilized a Carlisle TPO roofing membrane to waterproof this structure. Carlisle is the leading manufacturer of single ply roofing membranes in the Nation. They have a very exclusive group of top level commercial roofing contractors are certified to install their material on some of the largest roof in the Nation. Preferred Roof Services, Inc. is proud to be one those few certified contractors to represent flat Tacoma roofers in the Puget sound. With our special certification we are not only trained to install the product to the manufacturers specification we are also able to offer exclusive "no dollar limit warranties," which provide a 100% guarantee on both material and workmanship. 

New Flat Commercial Roof Installed In Tacoma, WA By Preferred Roof Services, Inc. 

TPO is short for Thermoplastic Polyolefin, which is a modified plastic compound that is used to make many of our plastic products such as vehicle bumpers and dashboards. TPO can be applied by either fully adhering the product with special adhesives or mechanically attaching the membrane with screws and plates. The seams of the membrane are heat welded together which forms a monolithic bond which is stronger than the membrane itself. Carlisle TPO comes in many colors including white which has a high solar reflective rate which helps to keep your buildings cooler and your energy bills down. Installing a TPO system is a great investment for your business or investment properties.

TPO Roof Installation By Preferred Roof Services, Your Preferred Lakewood Roofing Contractor

Whatever it is you do in life there are always moments and opportunities to help others and make their lives better. We call this a "hero" moment at Preferred Roof Services, Inc. Recently we were called out to look at a roof on Lake Louise, Lakewood, WA. When our sales representative Nickolas arrived he found a very troubled homeowner that was distraught over a recent contractor experience. She asked Nickolas to take a look at her roof explaining that a "professional roofer" had just finished a torchdown roofing system the week before. We took a look at the roof and were completely appalled at what we saw. You can see from the picture below that the installer was certainly not a professional roofing contractor in Lakewood, WA. In fact they seem to know very a little about installing torchdown at all!

Before   Above is a picture of the torchdown roof that was installed two weeks before this picture was taken. The roof system was failing and needed to be replaced. You can see in the top right hand corner that the workmanship and application was done poorly.

This was the perfect solution for our customer!
