Ice barrier
Self-adhering membrane is applied at the eaves and in valleys where ice dams and runoff hit hardest.

Shingle Roof Installation Denville, NJ
A roofer in Denville can install a new shingle roof from the deck up: drip edge, ice and water shield, underlayment, starter strip, shingles, flashing and ridge vent, whether the roof is on a new home, an addition or a reroof. Call (862) 421-0116 to reach a local roofer.
What you see from the street is maybe half of a shingle roof. Underneath sit the drip edge, an ice and water shield along the eaves and in the valleys, underlayment across the deck and a starter strip that seals the first course. Then come the flashing details and the ventilation, which decide whether the roof stays dry and how long the shingles last.
Shingle choice sets the look, the wind rating and the life of the roof. 3-tab shingles are thin and uniform, and architectural shingles are thicker laminated shingles with a textured, shadowed look and higher wind ratings. For hail-prone areas there are impact-resistant shingles, and lighter colors can help keep a sunny attic cooler.
Shingles are made for sloped roofs. The usual minimum for shingles is a 2 in 12 pitch, with a double layer of underlayment on slopes up to 4 in 12. A low porch or shed dormer may need a membrane section joined carefully to the shingles.
If the problem goes deeper than it first looked, a Denville 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.
Check the sheathing
On a reroof or new build, the deck is inspected and fixed first, since shingles follow every dip beneath them. Shingles laid on a bad deck show every flaw.
Ice barrier first
Drip edge goes along the eaves, then ice and water shield runs up from the eave edge and down every valley. Where ice dams form, codes call for the barrier to reach beyond the warm wall line.
Underlayment rows
Underlayment covers the deck in shingled rows, and the rake edges get their drip edge after it. It is the backup layer if wind ever drives water past the shingles.
Start at the eaves
A starter strip with factory sealant runs along the eaves and rakes so the first course and the edges are glued down. Skipping it is a common cause of edge blow-offs.
Nail the courses
Each course is nailed in the nailing zone, never high or overdriven, and step flashing goes in piece by piece at every sidewall. Counter flashing laps over the step flashing at chimneys and walls.
Ridge vent
A ridge vent is cut in along the peak and capped with hip and ridge shingles, balanced with soffit intake at the eaves. Mixing ridge vents with box vents can short circuit the airflow.
What is included
What a new shingle roof includes
Starter strip
The edges get drip edge and starter shingles so water drips clear of the fascia.
Choosing a shingle
The roofer helps compare shingle types so the look and performance both fit.
Synthetic underlayment
The whole deck is covered with lapped underlayment so wind-driven rain has a backup.
Ridge ventilation
Step, counter and kickout flashing, pipe boots and a ridge vent are installed new which is where most leaks would otherwise start.

Architectural Shingle Installation Denville, NJ
Architectural shingle installation follows the same order as any shingle roof, but the shingle has its own rules. The nails must land in the narrow area where the two laminated layers overlap, or the bottom layer can slip and the wind rating is lost. The ridge and hips get thicker cap shingles made for the line, not cut 3-tab pieces.
For Denville homeowners, architectural shingle installation has become the default for new roofs. 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 Denville, NJ
An asphalt shingle roof installation is the most common way to roof a house, and the details decide how well it performs. Problems on new roofs usually trace to high nails, skipped starter or reused flashing. Ask what layers will go down before the shingles and how the valleys will be done.
A new asphalt roof in Denville is usually installed in one to three days once the deck is ready. Cold weather slows the factory sealant, so shingles laid in winter may need hand sealing. The crew will watch the forecast, since wet decking cannot be covered.

What the local climate does to a roof
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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Denville, NJ have the roof checked in the fall and again after the snow melts.

Shingle Roof Installation FAQ
How steep does a roof need to be for shingles?
Shingles are made for slopes of 2 in 12 and steeper. 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. Flatter sections are roofed with a membrane instead.
What is the best season for a shingle roof installation?
Shingles go on best in mild, dry conditions. In cold weather shingles get stiff and the sealant strips need sun to bond, so roofers handle them carefully and often hand seal the edges. Wet decking is the hard stop at any time of year.
What goes under the shingles on a new roof?
Under the shingles sit drip edge, a self-adhering ice barrier in the leak-prone areas, a full layer of underlayment and starter shingles. Most roofers now use synthetic underlayment instead of felt, since it lies flat and resists tearing. Local code decides where ice barrier is required.
Why does nail placement matter on a shingle roof?
Shingles stay on because of correct nailing as much as sealant. Standard nailing uses four nails, and high-wind areas often require six. High or overdriven nails are a leading cause of blow-offs on newer roofs.
Which is better, 3-tab or architectural shingles?
A 3-tab shingle is thin and uniform, and an architectural shingle is thicker, heavier and layered. The thicker build gives architectural shingles better wind resistance and a longer life, and many lines no longer offer 3-tab. 3-tab can make sense on outbuildings or when matching an older roof.
