What Is Slate Roof Replacement?
Slate roof replacement strips a failing slate roof to the deck, repairs the sheathing, and reinstalls natural or synthetic slate on corrosion-resistant copper or stainless fasteners. It renews a heavy, long-lived covering that demands a load-rated structure.
What Slate Roof Replacement Is Available in Maplewood?
Newark Quality Roofing replaces natural quarried slate and synthetic composite slate on Maplewood's architect-designed Tudor, Colonial Revival, and Italian Revival homes. Slate roof replacement strips the slate to the deck, repairs the sheathing, and reinstalls slate on non-ferrous fasteners, the work that renews a slate roof when corroded fasteners and degraded flashing, not the slate itself, end its service life.
Natural and synthetic slate carry very different service lives: natural slate lasts 60 to 150 years, with premium slate commonly 100-plus years, per the InterNACHI life-expectancy chart and the National Slate Association, while synthetic slate lasts 10 to 35 years per the InterNACHI chart and premium composite slate is designed for 40 to 50 years per CertainTeed product literature. A Newark Quality Roofing replacement matches the new slate to the period roof it covers.
Corroded fasteners and degraded flashing end a Maplewood slate roof before the stone wears out, because plain steel and galvanized nails rust out long before the slate, per NPS Preservation Brief 29. A Newark Quality Roofing replacement renews the underlayment and the copper or stainless fasteners the slate hangs on, and rebuilds the valley, chimney, and wall flashing that admits water at the slate transitions.
Maplewood's older architect-designed stock often reveals deteriorated plank sheathing at tear-off, where decades of moisture under the slate have rotted the decking. A Newark Quality Roofing replacement strips the slate to the bare deck, replaces the rotted boards, and documents the slate pattern, coursing, and color before tear-off, per NPS Preservation Brief 4.
What Slate Roof Replacement Problems Are Common in Maplewood?
A slate roof cannot be roofed over, so a Maplewood slate replacement is always a full tear-off to the deck, per N.J.A.C. 5:23-6.4, because slate is listed among the coverings that require complete removal of the existing covering. A Newark Quality Roofing replacement strips the slate to the sheathing and renews the underlayment and fasteners beneath it.
Reservation-edge tree canopy loads slate roofs on Maplewood's western Wyoming section, where the South Mountain Reservation reaches into the township's wooded western and northwestern edge and drops leaf and branch debris into valleys and gutters. The trapped moisture and branch impact stress the slate valleys and flashing first, so a Newark Quality Roofing replacement rebuilds those transitions in a durable metal matched to the slate.
The 20% replacement threshold decides repair against replacement on a Maplewood slate roof: a slate roof with 20% or more of the slates broken, cracked, missing, or sliding is usually less expensive to replace than to repair individually, per NPS Preservation Brief 29, while below 20% selective slate repair is preferred. A Newark Quality Roofing assessment rates the roof against the threshold before quoting.

What Is Our Process for Slate Roof Replacement in Maplewood?
Newark Quality Roofing documents the existing slate roof and rates it against the 20% replacement threshold before quoting. A crew photographs, measures, and records the slate pattern, coursing, color, and dimensions, per NPS Preservation Brief 4, because slate is repaired rather than replaced whenever fewer than 20% of the slates are broken, cracked, missing, or sliding, per NPS Preservation Brief 29, and avoids walking on the brittle tiles.
Newark Quality Roofing strips the slate to the bare deck and reinstalls natural or synthetic slate on non-ferrous fasteners. A slate roof requires complete removal of the existing covering with no recover-over, per N.J.A.C. 5:23-6.4, so the crew renews the underlayment, replaces deteriorated plank decking exposed on Maplewood's older homes, and reinstalls natural slate on solid copper or stainless slater's nails set so the slate hangs on the shank rather than driven tight, per NPS Preservation Brief 29.
Newark Quality Roofing matches the slate, fasteners, and flashing to the slate's service life and never coats or seals the slate. Flashing rebuilds in copper, lead-coated copper, or terne-coated stainless steel matched to the slate, per NPS Preservation Brief 29, because degraded flashing, not the stone, is the common slate-roof leak source. A crew verifies watertight execution, runs a magnet sweep for nails, and documents the quarry source and grade for the owner's records.
