What Is Cedar Shake Roof Replacement?
Cedar shake roof replacement removes aging cedar shakes and shingles to the deck and installs new cedar over a ventilated nailing base. It renews a wood covering that relies on underlying airflow to resist rot and prolong service life.
What Cedar Shake Roof Replacement Is Available in Roseland?
Newark Quality Roofing replaces hand-split cedar shake and sawn cedar shingle roofs on the cedar-clad and period homes among Roseland's tree-shaded postwar colonials, ranches, split-levels, and Capes. Cedar shake roof replacement strips an aging wood roof to the deck, repairs the sheathing, installs a ventilated nailing base, and lays new cedar, rather than patching individual split shakes.

Hand-split cedar shake and sawn cedar shingle carry different service lives, where cedar shake lasts 20 to 40 years and cedar shingle 30 to 50 years, per the Cedar Shake & Shingle Bureau, with the InterNACHI life-expectancy chart listing wood at 25 years. Maintenance sets where in that range a Roseland cedar roof lands, because moisture-driven cupping, splitting, and rot end most cedar roofs.
A ventilated nailing base holds at least 1.5 inches of drying air space beneath the shakes, the airflow that slows the moisture-driven decay a cedar roof faces, per Cedar Shake & Shingle Bureau install guidance. Roseland's mature oak and maple canopy shades north-facing slopes that dry slowly, so a Newark Quality Roofing cedar install builds in the underside drying a wood roof requires.
A full tear-off is the only code-compliant path for cedar in Roseland, because N.J.A.C. 5:23-6.4 prohibits roofing over a wood-shake roof and over a water-soaked or deteriorated deck, per the NJ Rehabilitation Subcode. A Newark Quality Roofing replacement strips the old wood to the deck, replaces sheathing rotted under years of trapped moisture, and rebuilds the system from the deck up.
What Cedar Shake Roof Replacement Problems Are Common in Roseland?




Deck rot beneath aging cedar is frequently worse than the shake surface suggests, because the drying air space that cedar requires also lets airborne moisture reach the sheathing, decaying the plywood or board deck over decades. A Newark Quality Roofing replacement strips the cedar to bare deck and replaces deteriorated sheathing, the work N.J.A.C. 5:23-6.4 requires before new cedar goes on.
Cedar fire class governs material selection, because untreated cedar shakes and shingles are nonclassified under UL 790 and ASTM E108, pressure-impregnated fire-retardant cedar carries a Class B or Class C product class, and a Class A wood roof is achieved only as a tested assembly, per the Cedar Shake & Shingle Bureau Certi-Guard program. A Newark Quality Roofing cedar install documents the fire-class selection for the homeowner and any insurer.
Mature-canopy debris and shaded slopes stress a Roseland cedar roof harder than an open suburb, because the borough's heavy oak and maple canopy drops leaf load into valleys and keeps north-facing slopes damp. Moisture-driven cupping, splitting, and rot accelerate on slow-drying shaded slopes, per Cedar Shake & Shingle Bureau guidance, so a Newark Quality Roofing install builds in the underside drying that offsets the shade.

What Is Our Process for Cedar Shake Roof Replacement in Roseland?

Newark Quality Roofing rates the cedar roof against its 20-to-40-year shake and 30-to-50-year shingle service life, runs the InterNACHI flex test on suspect shakes, and checks the deck before quoting the replacement. A shake that cracks under light bending fails the flex test and signals advanced degradation regardless of surface appearance, per the InterNACHI flex-test guidance, and cupping, splitting, and rot across more than 25 to 30% of the field crosses the contractor-consensus area threshold that favors replacement.

Newark Quality Roofing selects new cedar by type and fire class and explains the wood fire ratings before tear-off. Untreated cedar is nonclassified under UL 790 and ASTM E108, pressure-impregnated fire-retardant cedar carries a Class B or Class C product class, and a Class A wood roof is a tested assembly of fire-retardant shakes over a fire-retardant cap sheet, per the Cedar Shake & Shingle Bureau Certi-Guard program and InterNACHI.

Newark Quality Roofing strips the cedar to the deck, repairs the sheathing, installs a ventilated nailing base, and lays the new cedar. A full tear-off exposes the deck for replacement of plywood or OSB rotted under the old cedar, the work N.J.A.C. 5:23-6.4 requires because the NJ Rehabilitation Subcode prohibits roofing over wood shake, and a ventilated nailing base holds at least 1.5 inches of drying air space beneath the shakes, per Cedar Shake & Shingle Bureau install guidance.

Newark Quality Roofing verifies the cedar install, runs a magnet sweep for nails at cleanup, and issues a written workmanship warranty on the labor. The workmanship warranty is separate from the manufacturer material warranty that covers factory defects, and the crew contains debris with ground tarps before leaving the property, per Integrity Home Exteriors verification guidance.
