Slate Roof Installation Montville, NJ
A roofer in Montville 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 (862) 420-3039 to talk with a local roofer about a new slate roof.
A slate roof starts with picking the stone. 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. Color stability matters too: unfading slate stays the same, while weathering slate changes tone over time.
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. Two nails per slate, copper or stainless and never driven tight, let the slate hang freely and keep it from cracking. Copper valleys and flashing are standard on slate, since lesser metals wear out decades before the stone does.
Many slate roof installation calls in Montville 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
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
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.
Lay the starter
At the eaves, a starter row and a raised cant strip set the first course at the correct pitch. 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. Headlap is set by slope, with more on lower pitches and less on very steep ones.
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.
Finish the ridge
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
What slate roof installation includes
Snow guards
Ridges and hips are finished in slate or copper to protect people, gutters and plantings below.
Valley metal
Long life metal is used at every flashing point to match the life of the slate.
Copper fasteners

Slate selection
An engineer or span check confirms the structure before any stone is ordered.

Natural Slate Roofing Montville, 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 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.
Choosing natural slate for a Montville 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. 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. 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. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Montville, NJ have the roof checked in the fall and again after the snow melts.

Slate Roof Installation questions
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.
Can my house support a slate roof?
Natural slate is heavy, often comparable to tile and several times the weight of shingles. Whether a particular house can carry it depends on the framing, so a structural check comes first on any conversion. Thinner slate or synthetic slate can be options where the framing falls short.
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 is easier to work, though it is not meant to last as long. Pick based on the lifespan you want and the look of the house.
Why are copper nails used on slate roofs?
Copper and stainless nails resist corrosion for as long as the slate lasts. Steel nails rust out and cause slates to slip, the most common failure on older slate roofs. Each slate gets two nails, driven so the slate hangs without being clamped.
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. In places with little snow, they are less of a concern.
