Residential Roof Replacement

A Portland roof replacement is a multi-phase engineering project. We perform a comprehensive “Surgical Tear-Off,” exposing the underlying deck to inspect for moisture intrusion that standard visual inspections miss. Utilizing GAF Master Elite® systems, we install a layered defense strategy including synthetic underlayments and precision ventilation.

For homes in neighborhoods like Laurelhurst and Mount Tabor, we ensure that every replacement adheres to the GAF Golden Pledge® standard, offering a 50-year non-prorated warranty that is backed by the manufacturer. We coordinate all Portland BDS inspections to ensure your property record is properly closed out.

The Portland Material Guide: Shingles vs. Metal vs. TPO

Choosing the right material for a Portland property requires understanding how materials respond to persistent humidity. Below is a technical breakdown of the systems we install across Multnomah County.

1. GAF Composite Shingles (The PNW Standard)

Our GAF Master Elite installations utilize shingles with StainGuard Plus™ Algae Resistance. These feature copper microspheres that neutralize moss growth for years. For homeowners in Mount Tabor, this is the most cost-effective way to get a 50-year system.

2. Standing Seam Metal (The High-Canopy Solution)

Metal roofing is the gold standard for homes in the West Hills. Traditional shingles can trap debris from the dense evergreen canopy, while metal roofs naturally shed debris and snow, offering a 75-year lifespan.

3. TPO & PVC Flat Roofing (The Commercial Core)

Flat roofs in the Portland Industrial District face unique challenges. We utilize 60-mil or 80-mil TPO membranes that are heat-welded at the seams, creating a monolithic, waterproof barrier impervious to winter rains.

The Silent Killer: Portland's Dry Rot Crisis

Flat roofs in the Portland Industrial District face unique challenges. We utilize 60-mil or 80-mil TPO membranes that are heat-welded at the seams, creating a monolithic, waterproof barrier impervious to winter rains.

How to Spot it Early:

  1. Spongy or “bouncy” feel when walking on the roof.
  2. Visible fruiting bodies at the eaves.
  3. Peeling paint on the fascia boards or soffits.
  4. A persistent musty odor in the attic space.

West Hills Premium Roof Replacement Project

This upscale residential property in Portland’s challenging West Hills was a prime candidate for a complete roofing system overhaul. The large, multi-level home, perched on a steeply sloped and manicured lot under a pristine clear blue sky, featured an ageing asphalt shingle roof that was well past its prime. Its complex architecture, numerous valleys, and varying pitches demanded a methodical, high-precision approach. Project Details
  • Location: West Hills, Portland, OR
  • Property Type: Large upscale residential estate
  • Existing Roof: Ageing asphalt shingle system
  • Project Scope: Complete full shingle tear-off and replacement
  • Replacement System: Premium architectural performance shingles engineered for longevity in the high-moisture Pacific Northwest climate.

1956 Ranch-Style Restoration in Laurelhurst

  • The Challenge: This classic 1956 ranch required a complete structural overhaul. A full tear-off revealed that decades of Pacific Northwest saturation had led to extensive dry rot on the rafter tails and significant portions of the structural sheathing.
  • The Solution: Our team performed detailed structural restoration, replacing all compromised sheathing to create a solid, level foundation. We installed GAF Timberline® HDZ shingles in Slate Gray, paired with high-performance underlayment to create a monolithic moisture barrier specifically designed for the damp Laurelhurst climate.
  • Result: The project was successfully closed out with the issuance of a GAF Golden Pledge® 50-Year Warranty. Keeping homes dry since 1984, we ensured this mid-century classic is protected for the next fifty years.

Frequently Asked Questions

Yes. Within the city limits, any full roof replacement requires a building permit from the Portland Bureau of Development Services (BDS). J&J handles the entire process, from filing drawings to the final inspection close-out.
In the damp PNW climate, poor ventilation traps warm, moist air in the attic, leading to "attic rain" (condensation) and mold. We install balanced intake and exhaust systems to prevent decking rot and ensure your shingle warranty remains valid.
Neighborhoods like Irvington and Ladd's Addition have strict material and profile requirements. We specialize in matching historic aesthetics with modern GAF composite systems that pass historic review while providing superior protection.
We utilize a surgical tear-off process during the rainy months, only removing sections that can be completely waterproofed by the end of the day. This ensures your home interior is never exposed to the elements.
Costs vary based on pitch, material, and city permitting fees. A standard residential replacement in Multnomah County typically ranges from $12,000 to $25,000, including full BDS compliance and GAF Master Elite warranties.
Typically, no. Most Oregon carriers view moss as a maintenance issue. Regular professional cleaning and preventative treatments are critical to preserving your coverage and extending the life of your roofing system.
Standing water is the primary threat to flat roofs in the Industrial District. We recommend bi-annual inspections to clear drain blockages and inspect heat-welded seams to ensure your monolithic barrier remains waterproof.
It represents four decades of local experience. We don't just patch leaks; we restore structural integrity. Our long-standing tenure means we've seen every PNW weather event and know exactly how to build systems that survive them.
