Shingle Roof Installation Tenafly, NJ
A roofer in Tenafly 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 (551) 355-3330 to reach a local roofer.
Shingles are only the top layer of a shingle roof. The layers under the shingles include drip edge, ice and water shield, underlayment and starter strip, each with its own job. Then come the flashing details and the ventilation, which decide whether the roof stays dry and how long the shingles last.
Choosing the shingle comes before any of the layers. 3-tab shingles are thin and uniform, and architectural shingles are thicker laminated shingles with a textured, shadowed look and higher wind ratings. Where hail is a concern, Class 4 impact-resistant shingles are worth a look, and your insurer can tell you whether they change anything on your policy.
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.
Shingle Roof Installation is often paired with shingle roof replacement and roof installation, depending on the cause.

How shingle roof installation works
A shingle roof is built from the eaves up, layer over layer.
Prepare the deck
On a reroof or new build, the deck is inspected and fixed first, since shingles follow every dip beneath them. Moisture trapped under underlayment causes buckling later.
Ice barrier first
Metal drip edge is fastened at the eaves, and a self-adhering ice barrier covers the eaves and valleys where water and ice collect. Where ice dams form, codes call for the barrier to reach beyond the warm wall line.
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. Most roofers now use synthetic, which resists tearing and lies flatter than felt.
Start at the eaves
The starter row seals the bottom edge and rakes of the roof. Without it, the first course has nothing holding its lower edge.
Shingle 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 either open metal or closed-cut shingle valleys.
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
Layers of a shingle roof system
Choosing a shingle
The roofer helps compare shingle types so the look and performance both fit.
Drip edge
Starter shingles and metal drip edge finish the eaves and rakes which keeps wind from peeling up the first course.
Flashing details
New flashing and balanced ventilation finish the system so the details match the shingles.
Ice barrier
An ice barrier lines the eaves, valleys and other leak-prone spots to seal around nails if water backs up.

Architectural Shingle Installation Tenafly, NJ
Architectural shingles go on over the same deck, underlayment and starter as any shingle, with their own nailing pattern. The double thickness only holds if the nails catch both layers, so placement is checked as the roof goes on. Compatible starter and cap products finish the edges and ridge cleanly.
Most new shingle roofs in Tenafly are architectural, and for good reason. They stand up to wind better than 3-tab, hide small dips in the deck and usually last longer. Color is worth picking in daylight against the brick or siding, since samples look different outdoors.

Asphalt Shingle Roof Installation Tenafly, NJ
Asphalt shingle roof installation is standard work, but the quality varies a lot from one crew to the next. 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 Tenafly is usually installed in one to three days once the deck is ready. In cool months the sealant strips take longer to bond, and the edges get extra attention. Rain delays are normal because the deck has to stay dry.

How the weather here affects roofs around Tenafly
Cold winters bring snow, ice and a long stretch of freezing nights. 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 Tenafly is busiest after a hard winter and before the next one.

Common questions about shingle roof installation
What goes under the shingles on a new roof?
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.
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. Rain and snow are the real limits, since a wet deck should never be covered.
What is the difference between 3-tab and architectural shingles?
3-tab shingles are a single flat layer with cutouts, while architectural shingles are two laminated layers. Architectural shingles generally have higher wind ratings, last longer and have a textured look, which is why most new roofs use them. A roofer can help weigh the two for your house.
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. Porches and additions below that line need a low slope material.
How many nails should each shingle have?
Nailing is what holds shingles down until the sealant bonds and long after. Four nails per shingle is common, with six where the shingle instructions or local code call for high-wind nailing. High or overdriven nails are a leading cause of blow-offs on newer roofs.
