Gresham’s Reliable Roof Replacement Contractor — No Layovers, No Shortcuts, Full Tear-Off
Most Gresham roof leaks are not a shingle problem — they're a flashing problem. A chimney where the counter-flashing has lifted. A roof-to-wall intersection where kickout flashing was never installed.
A valley without ice and water shield. VResh performs full tear-offs on every replacement, installs a complete flashing system at all penetrations and intersections, and does not begin a tear-off we cannot complete the same-day. Certified by CertainTeed, Owens Corning, and Malarkey. EPA Lead-Safe Certified. Licensed OR #241979. Free written estimates. (503) 272–6436.

Why Gresham Roofs Need Attention Now
Gresham's position at the eastern edge of the Portland metro creates a specific roofing challenge: the Columbia Gorge funnels wind from the east that accelerates wear on east-facing slopes, while the overall Willamette Valley rain pattern keeps north-facing surfaces perpetually damp and moss-prone. Most Gresham homes built in the 1960s–1980s are either on their first replacement or approaching it.
Wind Exposure — What the Columbia Gorge Does to East-Facing Gresham Rooflines
The Columbia Gorge acts as a wind funnel from the east, and Gresham sits directly at its western opening. East-facing roof slopes on Gresham homes experience wind-driven rain at angles that test eave flashing, starter strips, and ridge sealing in ways that west-side Portland roofs do not. Wind uplift is the primary failure mode. Owens Corning Duration shingles — with SureNail Technology rated to 130 mph — are specifically worth considering for east-facing Gresham rooflines.
Moss and Algae — The North-Facing Gresham Roof Problem
Gresham's climate is ideal for moss and algae colonization on roof surfaces: overcast for months at a time, low UV during the wet season, and high ambient moisture. North-facing slopes and heavily shaded rooflines develop moss and algae fastest. Left untreated, moss holds moisture against the shingles, accelerating granule loss and underlying deterioration. Malarkey shingles with Scotchgard-treated algae-resistant granules and CertainTeed's StreakFighter granules are worth the modest premium on Gresham's north-facing rooflines.
When Repair Makes Sense and When Replacement Is the Right Call
Not every roofing situation calls for replacement. A single leak at a chimney or pipe boot on a 12-year roof in otherwise good condition is a repair. Widespread granule loss, multiple simultaneous leaks, or a 25+ year roof showing system-wide failure is a replacement. VResh provides an honest assessment at the free estimate visit — we do not default to replacement when repair is the right recommendation.
What VResh Actually Does on a Gresham Roof Replacement
Full tear-off. Deck inspection. Complete underlayment system. Complete flashing system. Then the shingles. In that order, every time. Here is what that looks like on a Gresham home.
Full Tear-Off and Deck Inspection
Complete removal of all existing shingles, felt, and underlying layers. VResh does not install new shingles over existing roofing — full tear-off is required to inspect the deck and install a proper underlayment system. After tear-off, all sheathing is inspected for soft spots, delamination, mold, and structural damage.
What VResh Finds When We Tear Off Gresham Roofs
- Ice & water shield absent or insufficient — most Gresham homes from the 1960s–80s have no ice and water shield at the eaves, or installation that stops at the first 12 inches rather than extending 24 inches past the interior wall line as Oregon code requires.
- Missing kickout flashing at roof-to-wall intersections — the single most common cause of moisture damage in exterior walls adjacent to rooflines. Every dormer, addition corner, and garage-to-house intersection is a potential entry point without kickout.
- Deteriorated pipe boots — neoprene pipe boot flashing from the 1980s–90s is frequently dried, cracked, and actively leaking. A common cause of ceiling stains on roofs that otherwise appear to be in good condition.
- Continuous flashing at dormers instead of step flashing — continuous metal flashing at dormer sidewalls traps water behind the flashing. Individual step flashing interwoven with each shingle course is the correct installation.
Deck Repair
Any sheathing that is soft, delaminated, or showing structural problems is replaced before the underlayment goes on. Sheathing that has pulled away from rafters is renailed. This is a non-negotiable step — new roofing installed over a compromised deck has a shortened lifespan and fails the inspection.
Underlayment and Flashing System
The underlayment system determines how the roof performs when shingles fail or are compromised. VResh installs ice and water shield at all eaves and valleys, synthetic underlayment over the full field, and a complete drip edge system at all eave and rake edges.
What's Missing on Most Gresham Roofs We Inspect
- Ice & water shield at valleys — valleys channel the highest water volume on any roof. A valley without ice and water shield is vulnerable to early failure even when shingles are in good condition.
- Kickout flashing at all roof-to-wall intersections — without kickout diverters, every rain event sends runoff directly into the wall cavity at these intersections. VResh installs kickout on every project.
- New pipe boot flashing at all plumbing vents — we replace all pipe boots on every roofing project regardless of apparent condition. A $40 pipe boot that fails is a $2,000 ceiling repair.
Shingles, Ridge Cap, and Cleanup
Shingles are installed per manufacturer specifications — correct exposure, correct nailing zone, correct number of fasteners. Starter strip is installed at all eaves and rakes. Dimensional ridge cap is installed at all ridges and hip caps at all hips. Full perimeter cleanup including magnetic roller sweep for nails. Walk-through with the homeowner and written warranty documentation issued.
Roofing Products VResh Installs in Gresham
VResh is certified by three major manufacturers. Here is why each is relevant to Gresham homeowners specifically.
Malarkey — Portland-Made, Engineered for the Pacific Northwest
Malarkey is a Portland-based roofing manufacturer — one of the few premium brands that specifically formulates products for Pacific Northwest conditions. Their polymer-modified asphalt remains flexible through Gresham's freeze-thaw cycles and resists the brittleness that causes shingle cracking. Scotchgard-treated algae-resistant granules are particularly valuable on Gresham's north-facing and shaded rooflines. VResh recommends Malarkey Legacy and Vista as a strong first choice for most Gresham homes.
Owens Corning Duration — Rated for Gorge Wind Exposure
Owens Corning Duration shingles feature SureNail Technology with a wind resistance rating of up to 130 mph. For east-facing Gresham rooflines exposed to Columbia Gorge wind events, this rating is meaningful. Duration Premium with WeatherGuard HP is designed for high-wind and severe weather environments. VResh is Owens Corning certified.
CertainTeed Landmark and Presidential — Broad Application, Strong Warranty
CertainTeed's Landmark series (30-year architectural) and Presidential TL (40-year, shake-style) are among the most installed products in the Pacific Northwest. CertainTeed's SureStart PLUS warranty requires certified installation — VResh is CertainTeed certified. Landmark in Weathered Wood or Colonial Slate is the most commonly specified product on Portland-area and Gresham homes.
Roof Replacement Requirements for Gresham Homes
Lead Paint Consideration
Roofing replacement on pre-1978 Gresham homes can disturb lead-painted surfaces at trim, fascia, and exterior wall penetrations. VResh is EPA Lead-Safe Certified and follows RRP protocols when pre-1978 painted surfaces are disturbed during roofing work. Most Gresham homes built before 1978 qualify — Gresham's median construction year is approximately 1975.
