Cedar Shake Roofing
Cedar Shake Roof Installation Sparta, NJ
A Sparta roofer who installs wood roofs can lay new cedar shakes or shingles over solid or spaced sheathing, with open metal valleys and vented ridge caps, so the roof sheds water and dries out between storms. Call (973) 858-1854 to reach a local roofer.
How a cedar roof is put on matters more than the wood itself. Every detail, from the side gaps to the nail type, exists so the shakes can get wet, dry out and move without leaking. Done right, a cedar roof can serve a home for 30 years or more.
The first decisions are the wood and the style. Split shakes look rustic and heavy, sawn shingles look trim and even, and taper-sawn shakes sit in between. Top grades use edge-grain heartwood with no knots, the most stable wood for a roof.
Code and climate shape the rest. Shakes need a slope of at least 4 in 12 under most codes, while shingles can go on slightly lower slopes with reduced exposure. Wildfire codes, local permits and neighborhood rules can all affect which cedar product is allowed.
Depending on what the roofer finds, cedar shake roof installation in Sparta, NJ can go hand in hand with cedar shake roof replacement and cedar shake roof repair.

How cedar shake roof installation works
Each layer of a cedar roof has a job.
Set up the sheathing
The roofer installs either spaced 1x boards or solid sheathing covered with a ventilated underlayment mat. In cold areas, the lower edge gets solid sheathing and an ice and water barrier.
Start at the eaves
A strip of felt goes along the eave, then a doubled or tripled starter course of shakes or shingles overhangs the fascia by about an inch and a half. Edge metal along the eave and rakes protects the wood trim.
Install the shakes
Shakes go on in courses with felt interlay woven between them, positioned so it never shows below the next course. Side gaps are kept even, joints are staggered from course to course and the exposure follows the length and the slope.
Fasten correctly
Two corrosion-resistant nails per shake are placed just above the line where the next course will lap, keeping them out of the weather. Low-grade fasteners can fail decades before the wood, so the nail choice matters.
Flash the valleys
A wide open metal valley is installed, with shakes cut to a clean line on each side. Walls, skylights and vent pipes get their own flashing woven into the courses.
Cap the ridge
Hips and ridges are covered with cedar caps that alternate their overlap, nailed with longer fasteners into solid wood. Balanced ventilation under a wood roof keeps both the attic and the shakes drier.

Cedar Shingle Roof Installation Sparta, NJ
Shingles give a cedar roof a cleaner, more uniform look, and their installation reflects that. Shingles come in 16, 18 and 24 inch lengths and are laid with shorter exposures, often around 5 to 7 and a half inches depending on length and slope. Spacing between shingles is narrower than between shakes.
Unlike shakes, shingles do not get felt interlay between courses, because their tight, thin layering already gives three layers of wood coverage. Like shakes, shingles need air under them, so spaced boards or a breather mat are common. In Sparta, ask the roofer to explain which product suits your slope and style.

How the weather here affects roofs around Sparta
Cold winters bring snow, ice and a long stretch of freezing nights. 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. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Sparta, NJ have the roof checked in the fall and again after the snow melts.

Common questions about cedar shake roof installation
Are cedar shake roofs a fire risk?
Untreated cedar is combustible, which is why fire-retardant treated shakes exist. Treated shakes over a rated underlayment can meet stricter local codes. Local codes decide what is allowed, so ask before ordering.
Are cedar shakes and cedar shingles the same thing?
They are related but not the same product. Shakes are rugged and heavy with deep shadow lines, and shingles are trim and even. Shakes get felt between courses, shingles rely on overlap.
Do cedar shakes need a preservative treatment?
Whether to treat depends on moisture, shade and fire rules. In damp, shaded areas, preservative-treated shakes resist moss and decay better, and in fire-prone areas, fire-retardant treatment may be required. Your roofer can explain which options fit your Sparta home.
What kind of underlayment does a cedar roof need?
The deck under cedar is designed to let air reach the back of the wood. Shakes also get strips of felt interlay woven between each course, and an ice barrier goes along the eaves in cold climates. Everything under the shakes is chosen so the wood can breathe.
How steep does a roof have to be for cedar shakes?
Most codes call for at least 4 in 12 for cedar shakes. Sawn shingles allow a bit less pitch if the exposure is shortened. Flatter roofs drain too slowly for wood.
