We answer our phones live, 24 hours a day, at (844) 563-1816.
Redmond’s housing stock tells a specific story. The Microsoft-era buildout of the 1980s and 1990s left neighborhoods like Education Hill and the 98052 core with thousands of cedar shake and early-generation composite shingle roofs now hitting 30-45 years old. Many are failing simultaneously. Our Roof Replacement & Installation team has handled this exact scenario hundreds of times. We also serve Redmond homeowners in newer construction who need their first roof done right, not fast and cheap.
Why Ridgeline Roofing Co. Is Redmond’s Preferred Roof Replacement & Installation Company
We are not storm chasers. We are not a phone-book name that sends out whoever is available. Ridgeline Roofing Co. was founded in 1984, and we have spent over 42 years standing behind roofs we installed - not chasing the next hailstorm to the next state. In Redmond, that matters. Homeowners here tend to stay put. They remember who showed up after the last wind event, and who vanished.
Our technicians are background-checked, uniformed, and trained in-house. Every inspection is photo-documented from your actual roof, not a sales pitch in your driveway. The 90-Day Done Right Promise means what it says: if something is not right, we come back and make it right. No paperwork to file, no argument, no runaround.
A live person answers every call, day or night, weekend or holiday. That includes the middle of a January windstorm when a branch has punched through your sheathing and water is running down the drywall - exactly the kind of Emergency & Storm Damage - Redmond situation we handle. We will be there when we say.
Our pricing is upfront. The number on the estimate is the number on the invoice. A square deal: the price we quote is the price you pay.
Our Roof Replacement & Installation Services in Redmond
Full Roof Replacement
Most Redmond homeowners who call us for Redmond Roof Repair or replacement are facing the same situation: a 30-plus-year-old roof that has reached the end of its useful life. In the 98052 and 98053 ZIP codes, we regularly see cedar shake roofs installed during the 1980s tech boom that are now brittle, split, and leaking. Our full replacement process includes complete tear-off, deck inspection and repair, ice-and-water shield installation to code, and new shingles or alternative materials with proper ventilation. We handle permit pulls with the City of Redmond and schedule around weather windows that work for our climate.
Asphalt Shingles
Asphalt remains the most common choice for Redmond replacements, and we install GAF, CertainTeed, and Owens Corning lines with full manufacturer warranty registration. For Redmond’s moss-prone environment, we specify algae-resistant shingles and can add zinc or copper ridge strips that actively prevent colonization on north-facing planes. A typical 2,400-square-foot asphalt replacement in Redmond runs $12,000-$18,000 using architectural-grade products. We recently replaced a 35-year-old cedar shake roof on a 1980s split-level in the Education Hill neighborhood, where decades of fir canopy debris had accelerated decay to the point of interior water damage. Our crew installed GAF Timberline HDZ shingles with a zinc ridge strip to prevent moss regrowth, and reinforced flashing around the two skylights that had been leaking due to organic buildup in the valleys.
Flat Roofing
Redmond’s townhome developments and contemporary builds often incorporate low-slope sections, porches, or detached ADUs with flat or nearly-flat roofs. These demand different materials - TPO, modified bitumen, or standing-seam metal - and different drainage detailing. We install flat systems that handle Redmond’s higher-than-average rainfall without ponding, and we always verify that scuppers, drains, and Gutters & Accessories - Redmond are clear before we close out a job. Flat work in Redmond typically ranges $8,000-$15,000 depending on access and square footage.
New Construction
For builders and homeowners adding on in Redmond’s remaining infill lots, we provide complete roofing from rough framing inspection through final walk. We coordinate with framers and HVAC contractors to avoid the penetrations and ventilation conflicts that cause callbacks. Our familiarity with Redmond’s inspection schedule and the city’s specific wind-uplift requirements for exposed ridge locations keeps projects on track.

Trusted Brands We Service in Redmond
We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Redmond homeowners, this means genuine materials with full warranty backing, not closeout substitutions or gray-market products. We stock common GAF and Atlas shingle colors locally for faster turnaround on storm-damage replacements, and we register every warranty directly with the manufacturer so your coverage is intact whether you sell in two years or stay for twenty.
Common Roof Replacement & Installation Problems We See in Redmond Homes
- Improper flashing around skylights and valleys. In heavily canopied Redmond lots, moss and fir needles trap moisture against flashing that was never designed for perpetual damp. The result is rot that starts at the valley and works inward. We remove all old flashing, inspect the deck, and install new step flashing with ice-and-water shield backup.
- Shingle shrinkage and curling on aging 3-tab roofs. The prolonged damp understory conditions in 98053’s Plateau neighborhoods keep older shingles wet longer than manufacturer specifications assume. We see 30-year 3-tab roofs failing at year 22-25 in Redmond, not year 30. Architectural shingles with better resin content handle this environment more reliably.
- Alley-access interference in tight subdivisions. Redmond’s older neighborhoods were not built with 40-foot roll-off dumpsters in mind. Parked cars, narrow driveways, and HOA restrictions can delay material delivery and force incomplete tear-offs. We survey access before we quote and coordinate dumpster placement with neighbors when needed.
- Moss-driven accelerated decay on north-facing planes. Redmond’s dense Douglas fir canopy in neighborhoods like Education Hill causes north-facing roof planes to develop moss colonies within 3-5 years of installation, requiring proactive zinc or copper ridge strips that are rarely needed in more open suburban Eastside markets. Without this step, even a new roof can look twenty years old in half a decade.
Pricing for Roof Replacement & Installation in Redmond, WA
Roof replacement costs in Redmond reflect our local conditions: steeper pitches common in 1980s split-levels, tighter access increasing labor hours, and the deck repairs that often hide beneath decades-old cedar shakes. Here is what we typically see:
| Service | Typical Range in Redmond |
|---|---|
| Asphalt shingle replacement (2,000-2,800 sq ft) | $12,000-$18,000 |

| Tile roofing (clay or concrete) | $28,000-$45,000 |

| Cedar shake tear-off with full deck repair | $18,000-$28,000 |
| Zinc or copper ridge strip addition | $800-$1,500 |
Factors that push costs toward the higher end: multiple layers to remove, extensive deck rot in the fir-canopy zones, skylight replacement or addition, and steep pitches above 8:12.

FAQs - Roof Replacement & Installation in Redmond
North-facing planes in Education Hill stay shaded and damp for most of the year under Redmond’s dense Douglas fir canopy, creating conditions where moss colonies establish within 3-5 years of a new shingle installation. We install zinc or copper ridge strips as standard practice in these neighborhoods because the metal ions wash down the roof surface with rainfall and actively suppress moss growth. This is rarely necessary in more open suburban markets like Issaquah or Sammamish proper. Call (844) 563-1816 to discuss whether your lot conditions warrant this addition.
Architectural asphalt shingles from GAF or Atlas offer the best balance of moisture resistance, moss tolerance, and cost for most Redmond replacements. Their heavier fiberglass mat and better-quality asphalt resists the curling and shrinkage we see on older 3-tab products in damp 98053 conditions. For homeowners planning to stay 25-plus years, standing-seam metal eliminates moss attachment entirely and handles our higher rainfall without the degradation asphalt suffers. We will walk you through both options on your specific roof. Estimates are free.
We survey access during our initial inspection and coordinate dumpster placement, crane positioning, and material staging before tear-off day. In alley-loaded neighborhoods, we sometimes use smaller debris trailers rather than roll-offs, and we schedule deliveries for off-peak hours to avoid conflicts with parked cars. Our crews have handled tight Redmond lots for decades. Call (844) 563-1816 and we will assess your specific access situation.
Yes, for most Redmond homeowners, modern architectural asphalt shingles outperform cedar shake in our wet, moss-prone climate. Cedar requires annual treatment and still succumbs to rot in shaded, damp conditions. Asphalt shingles with algae-resistant granules and proper ventilation handle Redmond’s precipitation profile with minimal maintenance. We do install synthetic shake products for homeowners who want the aesthetic without the upkeep, but standard asphalt remains the practical choice. We will show you samples during your free estimate.
Zinc ridge strips release metal ions with every rainfall that wash down the roof and create a hostile environment for moss and lichen spores. In Redmond’s fir-canopied neighborhoods, this can extend effective shingle life by a decade or more compared to untreated roofs. The strips install at the ridge line, are invisible from the street, and require no maintenance or power connection. We consider them essential equipment for north-facing roofs in Education Hill and similar Redmond neighborhoods. Call (844) 563-1816 to include them in your replacement quote.
