Gig Harbor — Pierce County, WA
The roofing contractor can replace your shingles. They cannot legally repair the structural framing beneath them. When a Gig Harbor home inspection flags rotted rafter tails, ridge board deterioration, sheathing decay, or exposed beam end failure — that is a structural general contracting scope, not a roofing scope. Realty Repair Co. repairs what holds the roof up, under Washington State General Contractor License #APCONL*825QO. Forensic diagnostic. Written scope. Lump-sum fixed price. Five-year written structural guarantee.
The Gig Harbor Roof Framing Problem
When Gig Harbor homeowners call a roofing contractor, they are calling about the covering — the shingles, the underlayment, the flashing. Roofing contractors are licensed and skilled at that scope. They are not structural general contractors, and in Washington State, replacing or modifying structural roof framing members — rafters, ridge boards, collar ties, or structural sheathing serving as a diaphragm — is general contracting work under RCW 18.27. The gap between those two scopes is where Gig Harbor roof framing damage lives, unaddressed, for years.
The peninsula's combination of factors is specific: 40-plus inches of annual rainfall, a wet season that runs October through May with minimal UV between events, dense Douglas fir and cedar canopy on forested lots that blocks sun and accelerates moss colonization, and a housing stock built primarily between 1975 and 2005 when many roof assemblies used OSB sheathing and rafter tails were left with untreated end grain directly exposed to the eave environment. On Gig Harbor's waterfront and estate properties, the additional factor of exposed architectural timber framing — glulam beams and heavy timber purlins extending beyond the roof line — means structural wood is in direct marine air contact with no protective covering at the end-grain face.
The result: a roofing contractor who re-roofs a Gig Harbor home without a structural assessment is installing new shingles over framing members whose fiber integrity has not been verified. The new covering conceals the structural condition below it, potentially for another 20 to 30 years — until the next re-roof, the next sale, or the next catastrophic load event.
How Gig Harbor Homeowners Discover It
Roof framing decay in Gig Harbor does not arrive from a single source. The peninsula's climate and housing stock produce four distinct moisture entry pathways, each targeting different framing members and each presenting differently in an inspection report or a renovation reveal. All four lead to the same requirement: a licensed GC structural assessment before any covering work proceeds.
Forensic Diagnostic Output
A roof framing assessment is not a shingle condition inspection. Every structural member in the framing system is assessed by its specific failure mode, load classification, and repair or replacement threshold. The table below reflects the scope of a licensed GC diagnostic — the level of assessment required before any structural repair can be accurately priced or performed on a Gig Harbor home.
| Structural Member | Load Classification | Failure Mode in Gig Harbor Climate | Diagnostic Method & Repair Threshold |
|---|---|---|---|
| Rafter Tails Rafter extension beyond wall plate to eave line; fascia and soffit bearing point |
Primary Structure | End-grain moisture absorption from eave-line exposure; accelerated by gutter separation, failed drip edge, or overhanging vegetation. Decay advances from the cut end inward along the rafter toward the wall plate. Fascia rot is a downstream indicator — by the time fascia boards fail, rafter tail decay is typically 6 to 18 inches into the member. | Probe testing along rafter tail from end toward wall plate. Decay extent mapped per rafter bay. Repair by sistering new rafter tail segments to solid wood with structural connector hardware, or full rafter replacement where decay has progressed past the wall plate. New material treated at all cut surfaces with borate-based preservative. |
| Ridge Board / Ridge Beam Apex framing member; rafter bearing point at peak; structural beam in cathedral assemblies |
Critical Load Path | Moisture accumulation at ridge from inadequate ventilation in unventilated cathedral assemblies; skylight or ridge vent flashing failures channeling water directly onto ridge member. In open-beam construction, ridge beams are exposed to condensation cycling from interior humidity differentials. Decay at ridge is often bilateral — advancing down opposing rafter bays simultaneously from a single moisture source. | Attic access inspection where available; moisture meter readings at accessible ridge zones; probe testing at any soft or discolored zones. Cathedral ridge beam decay requires sheathing removal and temporary shoring during replacement. Replacement to IRC R802.3 and WAC 51-51-0802 specifications for ridge board sizing to rafter depth requirements. |
| Collar Ties / Rafter Ties Horizontal tension member connecting opposing rafters; resists outward thrust at wall plates |
Primary Structure | Attic moisture concentration from inadequate ventilation activates decay at collar tie bearing points and fastener locations. Failed collar ties allow rafters to spread outward at the wall plate, producing visible ridge sag or wall bowing before catastrophic failure. In Gig Harbor's older homes, missing or undersized collar ties are also a pre-code condition — not a decay issue, but a structural deficiency identified during diagnostic. | Attic inspection for collar tie presence, sizing, and condition per IRC R802.4.6. Decay assessment at bearing points and fastener locations. Replacement or supplementation with new dimensional lumber or engineered connector hardware as appropriate to rafter spacing and span. |
| Roof Sheathing Panels Structural diaphragm; fastener base for roofing material; bearing surface on rafter tops |
Primary Structure | OSB sheathing — dominant in 1990–2005 construction — edge-swells permanently on moisture contact at panel seams, producing fastener withdrawal degradation and telegraphing at the shingle surface. Plywood sheathing in older construction develops fungal decay at the rafter-contact surface first, invisible from above until the shingle is removed. Moss moisture loading accelerates both failure modes across broad roof zones. | Panel-by-panel probe testing at all soft, discolored, or buckled zones identified during diagnostic. Extent mapped before any shingle removal is authorized. New panel installation to IRC Table R803.1 sheathing specification. Roofing contractor coordinates shingle reinstallation over new structural sheathing after GC repair is complete and passed inspection. |
| Exposed Architectural Beam Ends Glulam or solid-sawn timbers extending beyond roof line on estate and post-and-beam properties |
Visible but Depth-Unknown | End-grain marine air exposure on Gig Harbor's waterfront and hillside estates produces surface checking and UV degradation that masks the depth of interior decay. A beam end with 2 to 4 inches of visible surface deterioration may have active fungal decay advancing 12 to 24 inches into the interior. Probe testing is the only diagnostic method — surface appearance consistently understates the extent of structural fiber loss. | Multi-point probe testing and bore-hole sampling at beam ends to map decay depth accurately. Options: full beam replacement where decay exceeds structural threshold; sistered repair using through-bolted pressure-treated or naturally durable insert where decay is limited to the outer section; borate fungicide injection into beam interior where active decay is present but fiber integrity is maintained. Each beam assessed and specified independently. |
| Fascia Backer Board Structural backing for fascia trim; bearing surface for gutter attachment at rafter tails |
Indicator Member | The fascia backer is the first structural member to show visible distress from rafter tail decay — but its condition understates what is happening in the rafter tails behind it. Replacing fascia without assessing and addressing rafter tail condition is a cosmetic repair that leaves the structural deficiency in place and conceals it behind new material. | Fascia backer rot is treated as a trigger for rafter tail assessment, not as a standalone repair item. Backer board replacement is scoped concurrently with rafter tail repair — it is included in the structural repair scope, not referred out to a separate trim contractor. |
The Critical Scope Distinction
When a Gig Harbor home inspector writes "rotted rafter tails" or "structural roof framing deterioration" on a Form 35R, the finding requires a structural general contractor response — not a roofing estimate. Here is the specific reason that distinction matters in a transaction.
Structural framing repair and roofing replacement are complementary — they are not the same scope, and they are not performed by the same contractor. The correct sequencing on a Gig Harbor home with both a framing deficiency and an aging roof covering: APCON LLC performs the structural framing assessment and repair first, replacing compromised rafters, sheathing, and collar ties to current code. Once the structural work passes permit inspection, the roofing contractor installs new shingles over a verified, structurally sound substrate with full fastener withdrawal capacity. The roofing warranty is then valid. The structural repair record closes the inspection finding. Both scopes are complete.
APCON LLC does not perform roofing installation. We will coordinate directly with your selected roofing contractor to sequence the scopes correctly — this coordination is a standard part of the structural repair proposal on any project where covering replacement is also needed.
How It Works
Related Services
The moisture conditions that decay rafter tails at the eave line are the same conditions that are simultaneously advancing into the wall framing below — the window and door rough openings, the top plates, and ultimately the mudsill at the foundation. On Gig Harbor's sustained-wet-season climate, roof framing repair scoped in isolation misses concurrent damage that will generate the next repair call.
