Slate Roof Installation Hawthorne, NJ
A Hawthorne 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 (862) 434-1182 reaches a nearby slate installer.
A slate roof starts with picking the stone. 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.
Before ordering slate, the roof framing needs a hard look. Natural slate is among the heaviest roof coverings, so framing built for shingles may need reinforcement before slate goes on. 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. 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.
Many slate roof installation calls in Hawthorne also turn up a need for slate roof replacement or slate roof repair.

Call nowThe process
The slate roof installation process
Every slate is placed and nailed by hand, and the layers below matter as much.
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.
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.
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. 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. Headlap is set by slope, with more on lower pitches and less on very steep ones.
Flash the details
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.
Finish 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
Underlayment
Sheathing is repaired and dried in lapped to shed water to the eaves.
Copper flashing
Open copper valleys and step flashing are installed instead of metals that wear out early.
Snow guards
The ridge and hips are capped in a traditional pattern to close the top of the roof.
Slate selection
An engineer or span check confirms the structure and reinforcement is planned if needed.

Natural Slate Roofing Hawthorne, 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 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 Hawthorne 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
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, building ice dams that push 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 Hawthorne is busiest after a hard winter and before the next one.

Slate Roof Installation questions
How long will a slate roof installation take?
Expect a longer schedule than shingles or tile, often several weeks for an average home. Complex rooflines, copper detailing and structural work add time. Once the underlayment is down, the house is protected from rain.
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 are most important above entries, walks and lower roofs. Where snow is rare, they may not be needed.
Which is better, hard or soft slate?
The main difference is durability: hard slate lasts longer than soft slate. 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?
Natural slate is heavy, often comparable to tile and several times the weight of shingles. 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.
What nails should be used for slate?
The nails have to last as long as the slate, which is why copper or stainless steel is standard. 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.
