Slate Roof Installation Weehawken, NJ
A roofer in Weehawken can install a natural slate roof, from checking that the framing can carry the stone to hanging each slate on copper nails with the right headlap and finishing the valleys and ridges in copper. Dial (551) 373-3025 to talk with a local roofer about a new slate roof.
The first choice on any slate roof is the slate itself. Different slates vary in durability as well as color, from long lived hard slate to softer slate with a shorter service life. Some slates hold their color, called unfading, while weathering slates shift in tone over the first years.
Before ordering slate, the roof framing needs a hard look. A slate roof weighs several times as much as asphalt shingles, and thicker slates weigh more, so a home switching from shingles often needs an engineer to review the rafters and sometimes add framing. Codes generally call for slate only on slopes of 4 in 12 or steeper, over solid sheathing.
How the slate is hung decides how long it lasts. Each slate is fastened with two copper or stainless nails driven so the slate hangs on them rather than being pinned tight, which lets the stone sit flat without cracking. Copper flashing at valleys, walls and chimneys is the usual match, because it lasts on the same timescale as the stone.
Many slate roof installation calls in Weehawken also turn up a need for slate roof replacement or slate roof repair.

Call nowThe process
What happens during a slate roof installation
Every slate is placed and nailed by hand, and the layers below matter as much.
Plan the roof
The job begins with the structure, the choice of slate and a layout that sets the exposure for every course. Exposure is the slate length minus the headlap, divided by two.
Prepare the deck
Underlayment goes over a solid deck, with ice barrier at the eaves where codes require it. Edge metal goes on along the eaves and rakes.
Start at the eave
At the eaves, a starter row and a raised cant strip set the first course at the correct pitch. The first exposed course goes directly over the starter, with its joints offset.
Hang the slate
Each course is laid to a chalk line with the vertical joints offset, and every slate is hung on two copper nails driven just enough to hold it. Headlap is set by slope, with more on lower pitches and less on very steep ones.
Flash the details
Step flashing, counter flashing and open copper valleys are built into the roof course by course. Snow guards help hold snow on the roof, since snow slides off smooth slate in heavy sheets.
Close the top
Hips and ridges are closed with slate laid in a saddle or combed pattern or capped with copper. A stock of spare slate is left with the owner for later repairs.
What is included

Natural Slate Roofing Weehawken, NJ
Natural slate roofing is quarried stone split into thin sheets, and its long life comes from the stone itself, not from coatings or additives. It will not burn or rot, and quality slate shrugs off weather for a very long time. Each slate is slightly different in thickness and texture, which gives the roof its handmade look.
Choosing natural slate for a Weehawken home means planning for a roof that may outlast everyone who installed it. Some owners compare natural slate with synthetic slate, which weighs less but lasts far fewer years. Ask the roofer to show real slate samples before ordering so you see the true color and texture.

What the local climate does to a roof
Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, building ice dams that push water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Weehawken, NJ have the roof checked in the fall and again after the snow melts.

Common questions about slate roof installation
Which is better, hard or soft slate?
The main difference is durability: hard slate lasts longer than soft slate. Soft slate can still be a good choice and is easier to cut and shape, but it wears sooner. Pick based on the lifespan you want and the look of the house.
What nails should be used for slate?
Copper and stainless nails resist corrosion for as long as the slate lasts. Rusted steel nails are the reason so many older slate roofs have slipped slates. Two nails hold each slate, set so it hangs loosely and does not crack.
Do slate roofs need snow guards?
Snow guards are common on slate because snow slides off smooth stone in heavy sheets that can damage gutters and hurt people below. They are most important above entries, walks and lower roofs. Where snow is rare, they may not be needed.
How heavy is a slate roof?
A slate roof weighs far more than shingles, with the exact load depending on the thickness of the slate. Homes built for slate carry it fine, but a house framed for shingles may need an engineer and added framing before switching. Where framing is limited, thinner slate or a lighter synthetic slate may work.
How long does it take to install a slate roof?
Expect a longer schedule than shingles or tile, often several weeks for an average home. Dormers, valleys, turrets and framing upgrades all extend the schedule. The roof is dried in early, so the house stays protected during the work.
