Flashing details
Step, counter and kickout flashing, pipe boots and a ridge vent are installed new so the details match the shingles.

Shingle Roof Installation Parsippany, NJ
A roofer in Parsippany can install a new shingle roof from the deck up: drip edge, ice and water shield, underlayment, starter strip, shingles, flashing and ridge vent, so the roof is sealed against wind-driven rain from the start. Call (862) 693-4349 to reach a local roofer.
Shingles are only the top layer of a shingle roof. Below the shingles go metal drip edge, a self-adhering ice barrier at the eaves and valleys, a layer of underlayment and a starter row at the edges. Flashing and attic ventilation round it out, and most leaks on newer roofs come from those details rather than the shingles.
The first decision is the shingle itself. Flat 3-tab shingles are a single layer with cutouts, while architectural, or dimensional, shingles are laminated from two layers for more thickness, depth and wind resistance. For hail-prone areas there are impact-resistant shingles, and lighter colors can help keep a sunny attic cooler.
Not every roof can take shingles. Below a 2 in 12 slope, water moves too slowly for shingles, so low sections get a membrane roof instead. Flat sections are flagged during the estimate so the right material goes on each part.
If the problem goes deeper than it first looked, a Parsippany roofer may also recommend shingle roof replacement or roof installation.

The order of a shingle installation
Here is the order a roofer follows on a new shingle roof.
Prepare the deck
Sheathing has to be flat, dry and well fastened, so loose sheets are renailed and damaged ones replaced. Moisture trapped under underlayment causes buckling later.
Ice barrier first
The eaves get drip edge and a band of ice and water shield, and the valleys get a full-length strip. That membrane seals around nails where ice backs water up.
Underlayment rows
The rest of the deck is covered in underlayment, lapped so each row sheds onto the one below, with rake drip edge on top. Synthetic underlayment is lighter, stronger and less likely to wrinkle than felt.
Starter strip
Starter shingles go on first at the eaves and rakes, putting a sealant line under the edge where wind lifts first. Skipping it is a common cause of edge blow-offs.
Install the field
The field is shingled with correct offsets and nailing, with step flashing, kickout flashing and pipe boots set as the courses reach them. Valleys are finished open with metal or closed-cut, depending on the shingle and the roof.
Ventilation at the ridge
Exhaust at the ridge is matched to intake at the soffits so air moves through the attic. Mixing ridge vents with box vents can short circuit the airflow.
What is included
Layers of a shingle roof system
Choosing a shingle
The style, color and wind rating are chosen up front and to the weather the roof will face.
Starter strip
Starter shingles and metal drip edge finish the eaves and rakes so water drips clear of the fascia.
Synthetic underlayment
Underlayment rows are lapped from the eaves up as the second line of defense.
Ice barrier
Self-adhering membrane is applied at the eaves and in valleys beneath the underlayment and shingles.

Architectural Shingle Installation Parsippany, NJ
Installing architectural shingles uses the same layers underneath, with a few details specific to laminated shingles. Each nail has to pass through both layers in the marked nailing zone, which is narrower than on a 3-tab shingle. Compatible starter and cap products finish the edges and ridge cleanly.
Most new shingle roofs in Parsippany are architectural, and for good reason. They resist wind, add depth to the roofline and outlast flat shingles. A sample board viewed outside, next to the siding, is the best way to choose a color.

Asphalt Shingle Roof Installation Parsippany, NJ
An asphalt shingle roof installation is the most common way to roof a house, and the details decide how well it performs. Most early leaks on new shingle roofs come from flashing, nailing or missing starter, not from the shingles. It is fair to ask which underlayment and ice barrier will go on and where.
Most asphalt shingle installs in Parsippany wrap up quickly once materials are on site. Shingles seal best in warm sun, so roofs installed in cold weather are often hand sealed along the edges. Plan around a dry stretch, since the deck should never be covered while wet.

Shingle Roof Installation Near Me
New shingle roofs in Parsippany go on everything from new houses and additions to reroofs of older homes. Older homes in Parsippany and nearby towns like Lake Hiawatha, Mountain Lakes, Boonton and Whippany often had felt underlayment and box vents, while new roofs usually get synthetic underlayment, ice barrier at the eaves and a ridge vent, which is why the system under the shingles deserves as much attention as the color. Looking for a shingle roofer near me? Ask about the full system, from drip edge to ridge.

What the local climate does to a roof
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, 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 Parsippany is busiest after a hard winter and before the next one.

Shingle Roof Installation FAQ
What is the minimum pitch for asphalt shingles?
Asphalt shingles need a slope of at least 2 in 12. Between 2 in 12 and 4 in 12, a double layer of underlayment or a full ice barrier is required to make up for slow runoff. Anything flatter needs a membrane roof such as TPO, EPDM or modified bitumen.
Why does nail placement matter on a shingle roof?
Shingles stay on because of correct nailing as much as sealant. Four nails per shingle is common, with six where the shingle instructions or local code call for high-wind nailing. Each nail has to sit in the nailing zone, flush with the surface, not too high and not driven through.
Which is better, 3-tab or architectural shingles?
The difference is construction: one flat layer for 3-tab, two laminated layers for architectural. The thicker build gives architectural shingles better wind resistance and a longer life, and many lines no longer offer 3-tab. 3-tab still works for sheds, garages or matching an existing roof.
What kind of underlayment should go under shingles?
Starting at the deck, a new roof gets drip edge, ice and water shield at the eaves and valleys, underlayment over the rest and a starter strip at the edges. Most roofers now use synthetic underlayment instead of felt, since it lies flat and resists tearing. Check that the shingle instructions and local code are both followed.
Can shingles be installed in cold weather?
Warm, dry days give the best results for a shingle install. Winter installs are possible, but the shingles need gentle handling and the sealant may not bond until warmer days. Wet decking is the hard stop at any time of year.
