We’ve been driving the same roads through Alderwood Manor since 2016 - from the original Manor plat off 164th St SW to the postwar ranches along the Bothell-Everett Highway. We know which lots still carry the dense alder canopy that gives this community its name, and which neighborhoods were built with low-slope framing never meant to bear the weight of modern laminated shingles. That local knowledge changes how we approach every job. Call (866) 850-9676 to speak with a live person now - no voicemail, no callback window.

Our Roof Replacement & Installation Services in Alderwood Manor
Full Roof Replacement
Most Alderwood Manor homes need a full tear-off rather than an overlay, and there’s a specific reason why. The historic Manor plat contains a concentration of 1920s-1950s bungalows and cottages that have been re-roofed one or more times over the decades. Many now carry two or even three layers of asphalt shingles, exceeding Snohomish County’s two-layer maximum and straining the original low-slope framing that was never designed for that load. On a recent tear-off in the original Manor plat off 164th St SW, our crew found the third layer of asphalt shingles had doubled the roof load. We removed all old layers, reinforced the framing, and installed GAF Timberline HDZ shingles with zinc strips to combat the accelerated moss growth from the overhanging alders. A full replacement with proper tear-off, deck inspection, and code-compliant ventilation typically runs $14,000-$24,000 for a standard Alderwood Manor bungalow.
New Construction Roofing
New builds in Alderwood Manor are relatively rare compared to neighboring Lynnwood, but when they happen - typically infill on subdivided Manor lots or custom homes near the Snohomish County line - we install from the deck up with proper slope engineering for the local climate. The Puget Sound lowlands around Alderwood Manor receive roughly 35-38 inches of annual precipitation concentrated in a seven-month rainy season. We spec materials and drainage that account for that reality, not a California dry-season manual.
Asphalt Shingle Installation
Asphalt shingles remain the practical choice for most Alderwood Manor homeowners, but the specific product matters more here than in drier climates. Standard three-tab shingles on low 3:12 pitches - common on postwar ranches throughout the area - pond water during sustained fall and winter rains, accelerating deterioration. We recommend architectural laminate shingles with enhanced sealant strips and, critically, zinc or copper ridge strips to combat the moss colonies that can establish within two to three years on shaded, damp roof surfaces. The mature alder canopy common on Manor-era lots keeps roof surfaces shaded and damp well into summer mornings. We install IKO and Atlas architectural lines with full manufacturer warranty registration, typically $12,000-$20,000 for an average Alderwood Manor home with complete tear-off.
Metal Roofing
Standing-seam metal roofing makes sense for Alderwood Manor homeowners who want to shed the alder debris and moss burden for good. Metal sheds catkins and leaf mats that would sit against asphalt shingles for weeks, holding moisture. A properly installed metal roof can outlast two or three asphalt cycles, though upfront cost runs $22,000-$35,000 for comparable square footage. We install Tamko metal shingle profiles and Boral stone-coated steel on select Alderwood Manor homes where the structure and budget align.

Trusted Brands We Service in Alderwood Manor
We are authorized installers for seven manufacturer lines - GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - and we stock the most common Alderwood Manor shingle colors and accessories locally to avoid the delays that stretch jobs across multiple wet weekends. For Manor-era homes with specific moss and load challenges, we frequently specify IKO Cambridge architectural shingles with ArmourZone reinforcement or Atlas StormMaster Slate for impact resistance where overhanging alders drop limbs. Every installation carries full manufacturer warranty plus our own 90-Day Done Right Promise on workmanship.
Common Roof Replacement & Installation Problems We See in Alderwood Manor Homes
- Multiple shingle layers exceeding code. Past re-roofs without tear-offs have left many original Manor plat homes carrying two or three layers, straining framing and voiding manufacturer warranties. We inspect with a core sample on every estimate.
- Moss and debris from dense alder canopy. Alders drop catkins in spring and leaves in fall in dense mats that sit against shingles and valleys, holding moisture for weeks. Roofers working the original Manor streets routinely find granule loss and premature tab cracking directly under overhanging alder limbs, a failure pattern less common on the more open-lot streets of neighboring Lynnwood or Mountlake Terrace.
- Low pitches on postwar ranches that pond water. The 3:12 pitches common on 1950s-1960s Alderwood Manor ranches drain poorly during the seven-month rainy season, accelerating deterioration of standard asphalt shingles that weren’t selected with slope in mind.
- Suppressed UV exposure retarding natural moss control. Overcast skies typical of the Puget Sound lowlands mean less ultraviolet radiation to slow biological growth. Roofs here can develop visible moss colonies within two to three years without preventive treatment - faster than sunnier inland locations.

FAQs - Roof Replacement & Installation in Alderwood Manor
The combination of dense alder canopy shade, 35-38 inches of concentrated annual rainfall, and suppressed UV exposure from overcast skies creates ideal moss conditions. Roofs here can show visible colonies within two to three years without zinc or copper strip treatment, faster than sunnier inland locations. We install preventive metal strips as standard on every Alderwood Manor replacement. Call (866) 850-9676 to discuss moss-resistant options for your specific roof exposure.
In most cases, yes. Many original Manor plat homes carry multiple re-roof layers that exceed Snohomish County’s two-layer code limit, and the original low-slope framing was never designed for modern laminated shingle weight. A tear-off lets us inspect and reinforce the deck, ensures manufacturer warranty validity, and eliminates the trapped moisture that accelerates failure. We core-sample during every free estimate to give you a definitive answer. Call (866) 850-9676 to schedule yours.
Architectural laminate shingles with enhanced sealant strips, installed with full ice-and-water shield in valleys and eaves, plus zinc or copper ridge strips for moss prevention. On pitches below 4:12, we may recommend a modified bitumen or TPO system instead of conventional shingles to handle ponding during the seven-month rainy season. We assess slope, drainage, and tree exposure before recommending. Call (866) 850-9676 for a specification tailored to your home.
Trim overhanging limbs back at least six feet from the roof plane, install gutter guards rated for fine debris, and specify algae-resistant shingles with copper granules. We also install zinc strips at the ridge line, which release metal ions during rain to suppress moss and biological growth. On recent Alderwood Manor jobs, we’ve found this combination extends clean-roof appearance from two years to six or more. Call (866) 850-9676 and we’ll include this in your replacement plan.
Sometimes a targeted repair suffices, but in Alderwood Manor’s older housing stock, isolated leaks often indicate systemic issues - multiple layers, saturated decking, or widespread granule loss under alder canopy. We offer free inspections with photo documentation so you can see what we’re seeing. If the roof is under fifteen years old and the damage is truly localized, we’ll recommend repair. If the underlying structure is compromised, we’ll show you why replacement saves money long-term. Call (866) 850-9676 for an honest assessment with no pressure.
