Slate Roof Installation Midland Park, NJ
A roofer in Midland Park 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) 370-0731 to talk with a local roofer about a new slate roof.
A slate roof starts with picking the stone. Slates are graded by how long they last, with hard slate outlasting soft slate, and they come in a range of natural colors. Some slates hold their color, called unfading, while weathering slates shift in tone over the first years.
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. Building codes typically require a minimum slope of 4 in 12 for slate, laid over a solid deck.
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 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.

The slate roof installation process
Here is how a slate roofer typically installs a new slate roof.
Choose the slate
The job begins with the structure, the choice of slate and a layout that sets the exposure for every course. Exposure is the slate length minus the headlap, divided by two.
Dry in the roof
Solid sheathing is checked and covered with underlayment, plus self-adhered membrane at eaves and valleys in cold climates. Edge metal goes on along the eaves and rakes.
Set the starter course
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.
Lay each course
The field slate goes on course after course with offset joints, consistent headlap and two nails per slate that are never driven tight. 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 help hold snow on the roof, since snow slides off smooth slate in heavy sheets.
Cap the ridge
Ridges and hips are finished with a saddle or combed ridge, mitered or Boston hips, or copper ridge caps. A stock of spare slate is left with the owner for later repairs.
What is included
A complete slate roof system
Copper fasteners
Slates are nailed loose enough to hang which keeps water out at every joint.
Deck preparation
Sheathing is repaired and dried in with ice barrier at eaves where needed.
Structural review
Slate is chosen by grade, size, thickness and color before any stone is ordered.
Ridge finish
Ridges and hips are finished in slate or copper with spare slate left for repairs.

Natural Slate Roofing Midland Park, 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. Each slate is slightly different in thickness and texture, which gives the roof its handmade look.
For a natural slate roof in Midland Park, the grade, thickness and color of the slate shape both the look and the lifespan. Synthetic slate is lighter and easier to install, but it does not carry the same lifespan as quality natural stone. Ask the roofer to show real slate samples before ordering so you see the true color and texture.

Roofs in this climate
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, 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. That is why roof repair in Midland Park is busiest after a hard winter and before the next one.

Common questions about slate roof installation
Why do slate roofs have 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. Where snow is rare, they may not be needed.
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.
What is the difference between hard and soft slate?
Slates vary by quarry, and hard slates outlast soft ones. 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.
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.
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. Steel nails rust out and cause slates to slip, the most common failure on older slate roofs. Two nails hold each slate, set so it hangs loosely and does not crack.
