Fast, Reliable Roof Replacement & Installation Across Tigard
A full roof replacement on a typical 1,500-square-foot Tigard home runs between $12,000 and $22,000 depending on materials and deck condition, and most jobs are completed in two to three days. Our crews are on Tigard roofs year-round, from the low-pitch ranches near Bull Mountain to the moss-shaded homes in Summerfield, and we answer the phone live at (844) 563-1816 every hour of every day.
We’ve been climbing Tigard roofs since 1984. We know the 1970s tract homes off Hall Boulevard, the custom builds above Bull Mountain, and the original Summerfield ranches where the Douglas fir canopy never quite lets the sun through. That local knowledge matters when you’re choosing how to ventilate a roof that sits damp for eight months straight, or whether your 1992 three-tab shingles have enough life left to survive another winter. We’re not driving up from out of state after a hailstorm. We’re the crew that trains apprentices in this market, sources materials through Portland distributors, and plans to be here when that new roof needs its first inspection.
Why Ridgeline Roofing Co. Is Tigard’s Preferred Roof Replacement & Installation Company
Homeowners in Tigard call us because we’ve earned a reputation for showing up when we say and leaving the job cleaner than we found it. We’ve replaced roofs on Summerfield ranches, Bull Mountain custom homes, and the split-levels lining Scholls Ferry Road, and our customers tell their neighbors. Our reviews from Tigard homeowners consistently mention the same things: the technician who explained the moss damage with photos taken from the actual roof, the estimator who gave one number and stuck to it, the crew that finished in two days instead of five.
We typically reach Tigard addresses within 45 minutes of a call, and we schedule replacement work to avoid the heaviest rain windows when possible. That matters here more than in drier markets. A roof torn off during a November deluge risks deck saturation that adds days and dollars. We watch the forecast, communicate clearly, and don’t start what we can’t finish dry.
Our 90-Day Done Right Promise applies to every Tigard job. If something is not right, we come back and make it right. No paperwork, no arguing, no runaround. That’s been our standard since 1984, and it’s why third-generation homeowners in this area still call Ridgeline.
Our Roof Replacement & Installation Services in Tigard
Full Roof Replacement
Most full replacements we handle in Tigard involve homes built between 1972 and 1995 with original or single-replacement asphalt shingles that have reached end of life. The defining challenge here is what we find underneath. In Summerfield and other heavily shaded neighborhoods, moss left untreated for a decade or more often destroys the underlayment before the shingles fail completely. We reroofed a 1977 ranch off 92nd Avenue in Summerfield where the homeowner’s deferred moss removal had turned the underlayment to dusty powder. After stripping the GAF Timberline shingles, we replaced 30% of the sheathing and installed CertainTeed Landmark PROs with a heavy-duty synthetic underlayment to handle Tigard’s persistent dampness. Every full replacement we quote in Tigard includes deck inspection and a line-item allowance for sheathing replacement, because discovering rotten wood after tear-off is not a surprise anyone deserves.
New Construction Roofing
New builds in Tigard are concentrated in the Bull Mountain area and infill pockets near downtown, with most featuring steeper pitches and more complex valley configurations than the 1970s ranch stock. We work with local builders and homeowners acting as their own general contractors to specify proper ice-and-water shield placement, ridge venting that accounts for our prolonged shoulder seasons, and flashing details that won’t fail where roof planes intersect. Our Roof Replacement & Installation team coordinates directly with your framing and siding crews to keep the envelope sealed and the schedule moving.
Asphalt Shingle Installation
Asphalt shingles remain the right choice for most Tigard homes, but product selection matters more here than in drier climates. We install GAF Timberline HDZ, CertainTeed Landmark PRO, and Atlas StormMaster Slate among other lines, and we specify algae-resistant granules and heavy-duty underlayment as standard, not upgrades. The 150 days of annual precipitation in Tigard, combined with minimal UV under tree canopy, means standard three-tab shingles often fail in 12-15 years instead of their rated 20. We explain the real-world performance difference so homeowners can choose between a 25-year architectural shingle and a 50-year designer line with eyes open. Our crews are authorized installers for seven manufacturer brands, so your warranty is valid, not voided by improper nailing or skipped ventilation.
Metal Roofing
Metal roofing makes sense for specific Tigard properties: low-pitch ranches where debris and moisture pool, homes in the densest canopy where moss would destroy any shingle, and homeowners planning to stay for decades. Standing seam metal sheds moss and lichen that would colonize asphalt, and its 40-70 year lifespan outlasts multiple shingle cycles. We install concealed-fastener systems in aluminum and steel, with proper thermal breaks and fastening patterns for our wet climate. Metal is not the cheapest option, but for a Bull Mountain home with a 3/12 pitch or a Summerfield ranch shaded by 80-foot firs, it can be the only option that doesn’t require re-roofing again in 15 years.

Common Roof Replacement & Installation Problems We See in Tigard Homes
- Moss-destroyed underlayment in shaded neighborhoods. The dense Douglas fir canopy throughout Metzger, Summerfield, and the Fanno Creek corridor keeps rooftops damp eight months a year. Moss and lichen colonization lifts shingle tabs, allows water migration, and gradually turns felt underlayment to pulp. By the time shingles show visible failure, the deck beneath may need extensive repair.
- Low-pitch drainage failures on 1970s-1990s ranches. The dominant 1,200-2,000 square foot ranch and split-level stock in Tigard features low-to-moderate pitches that pool needles, leaves, and moisture. Granule washes away, ice dams form at the eaves, and shingles designed for steeper pitches fail prematurely. We address this with proper synthetic underlayment, ice-and-water shield at critical zones, and ventilation upgrades.
- Simultaneous end-of-life cycling across suburban tracts. Tigard’s residential core was built in a concentrated wave from roughly 1972 to 1995, meaning thousands of roofs are failing within the same five-year window. This overwhelms small crews and attracts out-of-state storm chasers who rush installations and miss flashing details. We maintain sufficient crew capacity to schedule properly and inspect thoroughly.
- Granule loss accelerated by minimal UV exposure. Shingles need some sun to activate protective oils and maintain flexibility. Roofs perpetually shaded by Tigard’s mature canopy rarely get that curing, becoming brittle and crack-prone years faster than manufacturer estimates suggest. Product selection and maintenance timing must account for this reality.

FAQs - Roof Replacement & Installation in Tigard
The combination of dense Douglas fir canopy and decades of deferred moss treatment destroys underlayment and rots deck boards before homeowners notice interior leaks. In Summerfield specifically, original 1970s roofs with 10-15 years of untreated moss growth frequently require 20-40% sheathing replacement during reroofing. We build this expectation into every Summerfield estimate so you’re not caught off-guard when we open the roof. Call (844) 563-1816 for a free inspection and honest assessment of your deck condition.
We recommend algae-resistant architectural shingles with a 130-mph wind rating and heavy-duty synthetic underlayment, installed by an authorized contractor to preserve the warranty. GAF Timberline HDZ and CertainTeed Landmark PRO both perform well here, with granule technology that resists the moss and lichen colonization common under Tigard’s tree canopy. Standard three-tab shingles without algae resistance typically fail in 12-15 years in this climate, not their rated 20. We can show you side-by-side examples from local jobs when we visit for your estimate.
Not necessarily, but metal is often the most cost-effective long-term choice for pitches below 4/12 where debris and moisture pool. Low-pitch asphalt installations in Bull Mountain require meticulous ice-and-water shield application and more frequent maintenance to achieve reasonable lifespan. Standing seam metal eliminates the granule loss and tab-lifting issues that plague shingles on shallow pitches, and its 40-70 year lifespan means you won’t re-roof again. We’ll assess your specific pitch, tree cover, and budget to recommend the right product, not the most expensive one.
Most full replacements on standard Tigard homes take two to three days, and we schedule around weather windows to avoid exposing your deck during heavy rain. October through May brings our prolonged wet season, so we monitor forecasts closely, use tarps and temporary sealing as needed, and won’t tear off more than we can dry-in before nightfall. A job that might take two days in July could need three in November; we communicate this clearly when we schedule, and we don’t rush the waterproofing details that matter in a climate where roofs rarely fully dry out.
Yes. Manufacturer lines like GAF Timberline HDZ and CertainTeed Landmark PRO offer dimensional profiles and color blends that match or improve upon 1990s architectural shingles, and we carry sample boards showing how current products compare to aged installations we’ve replaced. Many 1990s split-levels in the Tigard area used early-generation architectural shingles that are now discontinued; we help you select a modern equivalent that complements your siding and trim. Photo-matching from your actual roof helps us get the aesthetic right, not just the function.
