We’ve been climbing Tigard roofs since 1984. That means we’ve watched the original 1970s tract homes in Summerfield cycle through their first, second, and sometimes third roofs. We’ve carried shingles up gravel drives on Bull Mountain acreages where delivery trucks couldn’t make the turn. We’ve learned that Tigard’s eight-month wet season and dense Douglas fir canopy create conditions you won’t find in drier parts of Oregon, and we plan our materials and scheduling accordingly. Our Specialty Roofing in Tigard work is built for homeowners who intend to stay put - people who want the job done once, with no callbacks.

Our Specialty Roofing Services in Tigard
TPO Roofing
TPO - thermoplastic polyolefin - is the flat and low-slope roof membrane we install most often on Tigard’s workshop additions, patio covers, and commercial-style residential builds. A typical TPO installation in Tigard runs $12,000-$18,000 for a 2,000-square-foot application. The white reflective surface helps during our brief but intense summer heat, and the heat-welded seams hold up against the 150 days of annual rainfall that keep most roofs damp from October through May. We install TPO from GAF and CertainTeed with proper insulation boards to prevent condensation in Tigard’s prolonged cool season.
EPDM Roofing
EPDM rubber roofing remains the workhorse for detached workshops and outbuildings across Tigard’s acreage properties, particularly in the Bull Mountain area where homeowners need a durable membrane for structures that see heavy use but don’t connect to the main home’s HVAC. A standard EPDM installation runs $10,000-$16,000. The black membrane absorbs heat, which actually helps shed the moss and debris that collect under Douglas fir canopy. We install fully adhered and mechanically fastened systems depending on your structure’s wind exposure and whether delivery trucks can reach the building or we’re hand-carrying materials up a rutted gravel drive.
Solar Ready Roofing
Solar ready roofing is what we recommend for any Tigard homeowner planning panel installation within the next five years, especially on south-facing workshop roofs in the Bull Mountain and Summerfield areas where acreage properties have the roof space and setback clearance. The upcharge for solar-ready prep - reinforced decking, proper flashing, and conduit routing - typically adds $1,200-$2,800 to a standard reroof. Doing it during the roof replacement saves the cost of tearing off new shingles later to install mounts. We coordinate with your solar contractor to ensure our GAF or Owens Corning system matches their rail specifications.
Modified Bitumen Roofing
Modified bitumen serves the same low-slope applications as TPO and EPDM but with a different installation approach: torch-applied or cold-adhesive layers that create a thick, puncture-resistant membrane. We see this most on older Tigard homes with 1970s-era additions where the original builder used built-up roofing and the homeowner wants compatible materials without full structural redesign. A modified bitumen overlay or replacement runs $9,500-$15,000. It’s not our first choice for new solar integration, but it’s a solid repair and replacement option when the existing deck and insulation are sound.

Trusted Brands We Service in Tigard
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines, no substitutions. For Tigard homeowners, this means we stock common membrane rolls, flashing kits, and underlayment at our westside warehouse rather than ordering from Portland and losing a day to traffic on Highway 99W. When we inspect your roof and identify the problem, we can usually specify the exact material and schedule installation without the delays that come from chasing parts. Our GAF and CertainTeed relationships are particularly relevant for Tigard’s moss-prone environment: both manufacturers offer algae-resistant shingle options that pair well with the synthetic underlayments we use on low-pitch ranch homes throughout Metzger and Summerfield.
Common Specialty Roofing Problems We See in Tigard Homes
- Moss and lichen destroy granule adhesion years ahead of schedule. The Douglas fir canopy throughout Tigard neighborhoods keeps rooftops shaded and damp through the extended rainy season. On low-pitch ranch homes built between 1972 and 1995, this biological growth lifts shingle tabs and voids manufacturer warranties - we’ve stripped roofs where the moss mat was three inches thick.
- Underlayment disintegration beneath untreated moss. In Summerfield specifically, we regularly find that original or single-replacement roofs were left unmaintained for 10-15 years. The moss holds moisture against the underlayment until it rots away entirely, requiring full deck inspection and often sheathing replacement on top of the reroof.
- Gravel drive access prevents material delivery on acreage properties. Bull Mountain and rural west Tigard lots often have drives that rut seasonally or carry debris from winter storms. When delivery trucks can’t reach the structure, we hand-carry materials or coordinate crane delivery - either way, we build that into our scheduling so the job finishes in one trip.
- Low-pitch designs pool debris and retain moisture. The dominant 1,200-2,000 square foot ranch and split-level stock in Tigard features roof pitches that don’t shed water aggressively. Without proper membrane selection and ice-and-water shield at valleys and penetrations, these roofs leak at the eaves during prolonged winter rain events.

These ranges reflect actual Tigard market pricing for 2024-2025, accounting for material transport to westside job sites and the deck repair frequency we see in this market. The biggest variable is always what we find when we strip the old roofing - which is why we include a full deck inspection in every estimate and photo-document the condition before we quote repair versus replacement.

FAQs - Specialty Roofing in Tigard
Because the concentration of 1970s-era homes with long-deferred maintenance means we regularly find underlayment that has completely rotted away beneath thick moss mats. We had a Summerfield job where the original asphalt shingles were buried under a moss mat so dense we couldn’t see the tabs. When we stripped them, the underlayment had rotted away entirely, so we replaced 12 sheets of sheathing and installed GAF Timberline shingles with synthetic underlayment - one trip, done right. Call (844) 563-1816 and we’ll inspect your deck condition before quoting.
TPO or EPDM, properly installed with adequate slope and drainage, outperforms shingle applications on pitches below 3:12 in Tigard’s 150-day rainy season. TPO’s heat-welded seams resist the prolonged moisture exposure that degrades shingle seal strips, while EPDM’s thickness handles debris accumulation under tree canopy. We assess your specific pitch, tree coverage, and budget before recommending. Call for a free evaluation.
If you plan to install panels within five years, solar-ready prep during your roof replacement saves $2,000-$4,000 compared to retrofitting later. Bull Mountain properties typically have the roof space and setback clearance, but workshop structures often need reinforced decking and proper conduit routing that standard roofing doesn’t include. We coordinate with your solar contractor to match rail specifications. Call (844) 563-1816 to discuss timing.
Most policies exclude damage from gradual deterioration or lack of maintenance, which is how insurers classify moss-related rot. Coverage typically applies only to sudden, accidental damage - a tree fall, wind event, or similar. We document everything with photos and can provide a detailed report if you want to file, but we recommend budgeting for deck replacement as a likely out-of-pocket cost on older Tigard homes. Call us for an honest assessment before you call your adjuster.
A properly installed TPO roof lasts 20-30 years nationally, but in Tigard’s specific conditions - 38 inches of rain across 150 days, minimal UV under Douglas fir canopy - we see 18-25 years as the realistic range. The critical factor is installation quality: heat-welded seams, proper insulation to prevent condensation, and attention to penetration flashing. Our 90-Day Done Right Promise covers the workmanship, and manufacturer warranties from GAF and CertainTeed protect the membrane itself. Call (844) 563-1816 for specifics on your project.
