Slate Roof Installation Rutherford, NJ
A Rutherford slate roofer can help you choose a slate, plan the layout and install the roof with fasteners and flashing that last as long as the stone. Dial (551) 380-1579 to talk with a local roofer about a new slate roof.
Slate is not one material but many, and choosing well comes first. Different slates vary in durability as well as color, from long lived hard slate to softer slate with a shorter service life. Color stability matters too: unfading slate stays the same, while weathering slate changes tone over time.
Slate is heavy, so the house has to be ready for it. Natural slate is among the heaviest roof coverings, so framing built for shingles may need reinforcement before slate goes on. Codes generally call for slate only on slopes of 4 in 12 or steeper, over solid sheathing.
The fasteners and flashing are what make a slate roof last. Slates are hung on two copper nails each, set just right so the slate is held but not clamped, since a nail driven too hard cracks the slate. Copper flashing at valleys, walls and chimneys is the usual match, because it lasts on the same timescale as the stone.
Slate Roof Installation is often paired with slate roof replacement and slate roof repair, depending on the cause.

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.
Choose the slate
Framing is checked, the slate is selected by grade, color and size, and the exposure is worked out from the slate length and headlap. The exposure works out to half of what is left once the headlap is taken from the slate length.
Dry in the roof
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.
Set the starter course
The roofer lays a starter course over a cant strip so the bottom row sits flat and sheds water like the rest. Joints in the first course are offset from the starter below.
Nail the field
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. Lower pitches get more headlap, and very steep pitches can use less.
Install copper flashing
Valleys, walls, chimneys and pipes are flashed in copper or another long life metal as the slate goes on. Snow guards are often added so snow does not slide off the slate in sheets.
Close the top
Ridges and hips are finished with a saddle or combed ridge, mitered or Boston hips, or copper ridge caps. Spare slates from the same lot are left for future repairs.
What is included
A complete slate roof system
Snow guards
Snow guards keep snow from sliding off in sheets to protect people, gutters and plantings below.
Underlayment
A solid deck is covered with underlayment before the starter course goes on.
Structural review
Slate is chosen by grade, size, thickness and color and reinforcement is planned if needed.
Copper flashing
Long life metal is used at every flashing point to match the life of the slate.

Natural Slate Roofing Rutherford, NJ
Natural slate roofing uses stone that has been quarried and split into slates, with no coatings or binders to wear off. It does not burn, it resists rot and insects, and good slate barely changes over generations. Natural variation in texture and edge gives every slate roof a distinct look.
Natural slate roofing in Rutherford is a long term choice, so it pays to match the slate grade to how long you want the roof to last. Some owners compare natural slate with synthetic slate, which weighs less but lasts far fewer years. Seeing actual slate samples, not just a brochure, helps you pick the right color and texture.

How the weather here affects roofs around Rutherford
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Rutherford is busiest after a hard winter and before the next one.

Slate Roof Installation FAQ
What nails should be used for slate?
Slate can outlast ordinary nails by many decades, so copper or stainless nails are used to match the life of the stone. 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.
Can my house support a slate roof?
Slate is among the heaviest roof coverings, several times the weight of asphalt shingles, and thicker slate weighs more. Whether a particular house can carry it depends on the framing, so a structural check comes first on any conversion. Where framing is limited, thinner slate or a lighter synthetic slate may work.
Which is better, hard or soft slate?
Hard slate is denser and can last well over a century, while soft slate gives a shorter, though still long, service life. 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.
How long will a slate roof installation take?
A slate roof takes considerably longer than a shingle roof, commonly several weeks. Dormers, valleys, turrets and framing upgrades all extend the schedule. The roof is dried in early, so the house stays protected during the work.
Do slate roofs need snow guards?
Smooth slate sheds snow all at once, so snow guards hold it in place to melt gradually. They matter most over doorways, walkways, decks and lower roofs. In places with little snow, they are less of a concern.
