Slate Roof Installation Fanwood, NJ
A roofer in Fanwood 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 (908) 663-5020 to talk with a local roofer about a new slate roof.
The first choice on any slate roof is the slate itself. Hard slate can last well over a century and soft slate somewhat less, and colors range from grays and blacks to greens, purples, reds and mottled blends. Unfading slate keeps its color, and weathering slate mellows to new shades with exposure.
The structure comes before the stone. 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. 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 valleys and flashing are standard on slate, since lesser metals wear out decades before the stone does.
Many slate roof installation calls in Fanwood also turn up a need for slate roof replacement or slate roof repair.

What happens during a slate roof installation
A slate roof is built slowly and by hand, one course at a time.
Check the structure
The roofer confirms the framing and deck can carry the slate, helps choose a grade, size and thickness, and lays out the pattern and exposure. The exposure works out to half of what is left once the headlap is taken from the slate length.
Prepare the deck
The deck is sheathed or repaired, then covered with underlayment, with ice barrier membrane at the eaves and in valleys where the climate calls for it. Drip edge and a cant strip at the eaves come next.
Start at the eave
The roofer lays a starter course over a cant strip so the bottom row sits flat and sheds water like the rest. The first exposed course goes directly over the starter, with its joints offset.
Nail the field
Course by course, slates are set with offset joints and the right headlap, each hung on two copper or stainless nails. Headlap is set by slope, with more on lower pitches and less on very steep ones.
Install copper flashing
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. Spare slates from the same lot are left for future repairs.
What is included
A complete slate roof system
Underlayment
Underlayment and ice barrier go down before the starter course goes on.
Proper headlap
Each course gets the headlap the slope calls for so they lie flat without cracking.
Ridge finish
The ridge and hips are capped in a traditional pattern with spare slate left for repairs.
Valley metal
Long life metal is used at every flashing point as the slate goes on.

Natural Slate Roofing Fanwood, NJ
Natural slate is real rock, split by hand into roofing slates, which is why it can last longer than nearly any other roof covering. It is fireproof, does not rot and holds up to weather for generations when it is properly hung. Each slate is slightly different in thickness and texture, which gives the roof its handmade look.
Natural slate roofing in Fanwood is a long term choice, so it pays to match the slate grade to how long you want the roof to last. Synthetic slate is lighter and easier to install, but it does not carry the same lifespan as quality natural stone. Seeing actual slate samples, not just a brochure, helps you pick the right color and texture.

Roofs in this climate
Cold winters bring snow, ice and a long stretch of freezing nights. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, building ice dams that push water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Fanwood, NJ have the roof checked in the fall and again after the snow melts.

Slate Roof Installation FAQ
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. Each slate gets two nails, driven so the slate hangs without being clamped.
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. Complex rooflines, copper detailing and structural work add time. The roof is dried in early, so the house stays protected during the work.
What is the difference between hard and 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. The right choice depends on how long you want the roof to last and what matches the home.
Do slate roofs need snow guards?
Smooth slate sheds snow all at once, so snow guards hold it in place to melt gradually. 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?
Slate is among the heaviest roof coverings, several times the weight of asphalt shingles, and thicker slate weighs more. 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.
