Slate Roof Installation Orange, NJ
A Orange 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. One call to (973) 858-1825 reaches a nearby slate installer.
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. Unfading slate keeps its color, and weathering slate mellows to new shades with exposure.
Slate is heavy, so the house has to be ready for it. 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. Slate also needs a solid deck and a slope of at least 4 in 12 under typical building codes.
A slate roof is only as long lived as its nails and metal. 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 Orange also turn up a need for slate roof replacement or 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.
Check the structure
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. Edge metal goes on along the eaves and rakes.
Lay the starter
A starter course goes on at the eave over a cant strip, so the first exposed course lies at the same angle as 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. Headlap is set by slope, with more on lower pitches and less on very steep ones.
Install copper flashing
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.
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.

Natural Slate Roofing Orange, 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. Natural variation in texture and edge gives every slate roof a distinct look.
Natural slate roofing in Orange 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 Orange
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. 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. That is why roof repair in Orange is busiest after a hard winter and before the next one.

Slate Roof Installation questions
How long does it take to install a slate roof?
A slate roof takes considerably longer than a shingle roof, commonly several weeks. Dormers, valleys, turrets and framing upgrades all extend the schedule. Once the underlayment is down, the house is protected from rain.
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 is easier to work, though it is not meant to last as long. The right choice depends on how long you want the roof to last and what matches the home.
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.
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. Thinner slate or synthetic slate can be options where the framing falls short.
Do slate roofs need snow guards?
Slate is smooth and steep, which lets snow slide off suddenly, and snow guards prevent that. They matter most over doorways, walkways, decks and lower roofs. In places with little snow, they are less of a concern.
