A roof replacement is one of the largest home investments you will make. The contractor you choose determines whether that investment holds for 25 years or starts showing problems in 5. Norken Roofing's replacement crews in Washington are certified applicators for the materials they install, which means the manufacturer warranties stay valid -- something that requires an approved contractor with documented installation processes.
Why Norken Roofing
Manufacturer certifications require documented training. We are approved to install the systems we sell -- which is how the manufacturer warranty stays intact.
The scope of work, material specifications, and total price go to you in writing before we schedule. No verbal agreements, no scope creep surprises.
We replace all chimney, valley, and penetration flashing as part of every replacement. Installing new shingles over old flashing is a shortcut we do not take.
We run a magnetic nail sweep, haul all debris, and leave your property clean every single day -- not at project completion, every day of the installation.
Replacement Services
Roof replacement is not a single service -- it is a series of decisions about materials, preparation, and installation method. Here is how we approach each component.
We do not install over existing roofing. Every replacement starts with a complete tear-off down to the deck -- removing all shingles, felt, and in many cases multiple prior layers. This is not simply best practice; it is required for full manufacturer warranty coverage in most cases, and it gives us direct access to assess the deck condition across the entire roof surface. We document any areas of soft, delaminated, or rotted decking before beginning installation, so you know exactly what is being replaced and why. Most contractors will not find these issues until they are already removing old materials -- we make sure you have the information and the written cost before the replacement shingles go on.
Dimensional or architectural shingles are the standard for residential replacement in most of Washington, and for good reason -- they offer significantly better wind and impact resistance than 3-tab products, carry longer manufacturer warranties, and provide a richer visual profile. We work with multiple shingle lines across a range of price points and performance ratings, and we can show you physical samples and spec sheets so you understand what you are purchasing. Wind resistance ratings range from Class D through Class H, and hail resistance varies by product line -- details that matter a great deal in DC weather.
The roofing system is not just shingles -- it is the full assembly below them. Synthetic underlayment has replaced felt paper as the standard on quality replacements: it is dimensionally stable, it does not wrinkle and ripple under shingles, it sheds water if it becomes exposed before shingles are laid, and it is significantly more durable during installation. In areas of Washington susceptible to ice dam formation or heavy wind-driven rain, we install self-adhering ice and water shield at the eaves, valleys, and around penetrations as a secondary water management barrier.
The most common cause of premature failure on a new roof is old flashing. We replace all chimney flashing, counter flashing, step flashing, valley flashing, and pipe boot flashings as a standard component of every replacement. Keeping original flashing and installing new shingles around it is a practice that leads to leaks within a few years -- the two materials age at different rates and the connection between them fails. Our crews are trained in proper flashing sequencing so that every transition point sheds water correctly and every component is interlocked rather than surface-sealed with caulk.
A roof replacement is also the right time to assess and upgrade attic ventilation. Inadequate ventilation accelerates shingle aging by trapping heat, creates moisture buildup that leads to mold and rot, and in cold climates contributes to ice dam formation. We assess your current ventilation configuration during the project and can install ridge vent, soffit baffles, or gable ventilation upgrades as part of the replacement scope. A properly ventilated attic extends shingle life and protects the structural components your new roof is installed over.
A significant number of roof replacements in Washington follow storm events and are wholly or partially covered under homeowners insurance. If you have experienced hail, high wind, or storm damage, we can walk through the inspection process with your adjuster, provide documentation of the damage we find, and help ensure the scope submitted for your claim accurately reflects the work required. We do not inflate claims, but we also will not let adjusters reduce scope in ways that leave your roof underprotected. Our goal is an accurate assessment that results in a properly completed replacement.

Reviews
"I got four bids for my roof replacement. Two were significantly lower because they proposed installing over my existing roof without tearing it off. Norken Roofing explained exactly why that is problematic -- the manufacturer warranty becomes void, you cannot assess the deck, and you are adding weight. I went with them and the difference in quality was evident from the first day. The deck had two sections of soft plywood they identified and replaced. The new roof has been on for 16 months without a single issue."
"My insurance company initially approved a partial repair after our hail storm. Norken Roofing's team came out with their own documentation of the damage and worked with my adjuster to get the full replacement approved. They were professional throughout the process -- factual, documented, not pushy. The replacement was completed in two days and the site was completely clean when they left."
"I appreciated getting a true line-item breakdown of the estimate. I knew exactly what I was paying for the tearoff labor, the decking repair per sheet, the underlayment, the shingles per square, and the flashing work. No other contractor gave me that level of detail. When the final bill came it matched the estimate to the penny plus the one additional deck board they found and documented before installing it."
