Deck underlayment
Underlayment rows are lapped from the eaves up before any shingle goes down.
Shingle Roofing
Shingle Roof Installation Randolph, NJ
A new shingle roof in Randolph is a system of layers, and each one has to go on in the right order for the shingles to do their job, with nailing and flashing done to the shingle instructions. Dial (973) 858-1826 to talk with a local roofer about a new shingle roof.
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 at every wall, chimney, valley and pipe, plus intake and exhaust ventilation, finishes the system.
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.
Shingles are made for sloped roofs. Asphalt shingles generally need a slope of at least 2 in 12, and roofs between 2 in 12 and 4 in 12 need extra underlayment. Porches and low additions often need a different material where they tie into the main roof.
Depending on what the roofer finds, shingle roof installation in Randolph, NJ can go hand in hand with shingle roof replacement and roof installation.

The order of a shingle installation
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. That membrane seals around nails where ice backs water up.
Lay the underlayment
Underlayment covers the deck in shingled rows, and the rake edges get their drip edge after it. Most roofers now use synthetic, which resists tearing and lies flatter than felt.
Set the first course
Starter shingles go on first at the eaves and rakes, putting a sealant line under the edge where wind lifts first. That is where wind damage usually begins on a poorly built roof.
Nail the courses
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.
Ventilation at the ridge
Exhaust at the ridge is matched to intake at the soffits so air moves through the attic. Balanced airflow keeps the attic cooler and drier and helps the shingles last.
What is included
Parts of a shingle installation
Starter strip
Drip edge and a sealed starter row protect the roof edges for a clean, sealed edge.
Shingle selection
3-tab, architectural or impact-resistant shingles are matched to the house before materials are ordered.
Ice barrier
Self-adhering membrane is applied at the eaves and in valleys where ice dams and runoff hit hardest.
Flashing details
Every wall, chimney and pipe gets new flashing, and a ridge vent caps the peak so the details match the shingles.

Architectural Shingle Installation Randolph, NJ
Installing architectural shingles uses the same layers underneath, with a few details specific to laminated shingles. The double thickness only holds if the nails catch both layers, so placement is checked as the roof goes on. Matching hip and ridge cap shingles and a compatible starter keep the look and wind rating consistent.
Most new shingle roofs in Randolph 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. Look at a few colors on a nearby roof in daylight before deciding.

Asphalt Shingle Roof Installation Randolph, 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. Ask what layers will go down before the shingles and how the valleys will be done.
For an asphalt shingle roof installation in Randolph, plan for a few days of work on an average house. In cool months the sealant strips take longer to bond, and the edges get extra attention. Plan around a dry stretch, since the deck should never be covered while wet.

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. That is why roof repair in Randolph is busiest after a hard winter and before the next one.

Shingle Roof Installation questions
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. Synthetic underlayment has largely replaced felt because it is lighter, stronger and less likely to wrinkle or tear. Local code decides where ice barrier is required.
What is the best season for a shingle roof installation?
Warm, dry days give the best results for a shingle install. Cold-weather installs are done regularly, with extra care for brittle shingles and hand sealing where the strips will not activate. Wet decking is the hard stop at any time of year.
What is the minimum pitch for asphalt shingles?
The usual minimum for shingles is a pitch of 2 in 12. Roofs that are low but still within range get added underlayment protection. Porches and additions below that line need a low slope material.
What is the difference between 3-tab and architectural shingles?
A 3-tab shingle is thin and uniform, and an architectural shingle is thicker, heavier and layered. Architectural shingles generally have higher wind ratings, last longer and have a textured look, which is why most new roofs use them. 3-tab still works for sheds, garages or matching an existing roof.
How many nails should each shingle have?
Nailing is what holds shingles down until the sealant bonds and long after. Standard nailing uses four nails, and high-wind areas often require six. Each nail has to sit in the nailing zone, flush with the surface, not too high and not driven through.
