Slate Roof Installation Paramus, NJ
A roofer in Paramus 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) 383-2304 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. Building codes typically require a minimum slope of 4 in 12 for slate, laid over a solid deck.
The fasteners and flashing are what make a slate roof last. Two nails per slate, copper or stainless and never driven tight, let the slate hang freely and keep it from cracking. Copper flashing at valleys, walls and chimneys is the usual match, because it lasts on the same timescale as the stone.
Depending on what the roofer finds, slate roof installation in Paramus, NJ can go hand in hand with slate roof replacement and slate roof repair.

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
The job begins with the structure, the choice of slate and a layout that sets the exposure for every course. The exposure works out to half of what is left once the headlap is taken from the slate length.
Prepare the deck
Underlayment goes over a solid deck, with ice barrier at the eaves where codes require it. Drip edge and a cant strip at the eaves come next.
Lay the starter
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.
Hang the slate
Course by course, slates are set with offset joints and the right headlap, each hung on two copper or stainless nails. Lower pitches get more headlap, and very steep pitches can use less.
Flash the roof
Copper step flashing is woven in along walls and dormers, counter flashing is set into chimney mortar joints and valleys are lined with copper. Snow guards are often added so snow does not slide off the slate in 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
Ridge finish
The ridge and hips are capped in a traditional pattern to protect people, gutters and plantings below.
Valley metal
Open copper valleys and step flashing are installed to match the life of the slate.
Structural review
Slate is chosen by grade, size, thickness and color before any stone is ordered.
Copper fasteners
Every slate hangs on two copper or stainless nails so the fasteners last as long as the stone.

Natural Slate Roofing Paramus, NJ
Natural slate roofing uses stone that has been quarried and split into slates, with no coatings or binders to wear off. It will not burn or rot, and quality slate shrugs off weather for a very long time. Natural variation in texture and edge gives every slate roof a distinct look.
Natural slate roofing in Paramus 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.

What the local climate does to a roof
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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Paramus, NJ have the roof checked in the fall and again after the snow melts.

Common questions about slate roof installation
Why are copper nails used on slate roofs?
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.
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.
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. 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?
Slates vary by quarry, and hard slates outlast soft ones. 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.
How long does it take to install a slate roof?
A slate roof takes considerably longer than a shingle roof, commonly several weeks. Complex rooflines, copper detailing and structural work add time. Once the underlayment is down, the house is protected from rain.
