Ice barrier
Self-adhering membrane is applied at the eaves and in valleys to seal around nails if water backs up.

Shingle Roof Installation Cranford, NJ
A Cranford roofer can help you pick between 3-tab, architectural and impact-resistant shingles and install the full system beneath them, whether the roof is on a new home, an addition or a reroof. Call (908) 562-6887 to reach a local roofer.
A shingle roof works as a system, not as a single product. 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.
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.
Shingles are made for sloped roofs. Below a 2 in 12 slope, water moves too slowly for shingles, so low sections get a membrane roof instead. 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 Cranford roofer may also recommend shingle roof replacement or roof installation.

How shingle roof installation works
Each layer goes on in a set order so water always runs over, never under.
Check the sheathing
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.
Seal the edges
Metal drip edge is fastened at the eaves, and a self-adhering ice barrier covers the eaves and valleys where water and ice collect. In cold climates the ice barrier extends past the inside of the exterior wall.
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
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
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.
Cap the roof
The ridge gets a continuous vent and cap shingles, and the soffits are checked for open intake. Too little intake makes a ridge vent pull air the wrong way.

Starter strip
Starter shingles and metal drip edge finish the eaves and rakes for a clean, sealed edge.
Deck underlayment
The whole deck is covered with lapped underlayment before any shingle goes down.
Flashing details
New flashing and balanced ventilation finish the system so the details match the shingles.

Architectural Shingle Installation Cranford, NJ
Architectural shingle installation follows the same order as any shingle roof, but the shingle has its own rules. Each nail has to pass through both layers in the marked nailing zone, which is narrower than on a 3-tab shingle. The ridge and hips get thicker cap shingles made for the line, not cut 3-tab pieces.
In Cranford, NJ, architectural shingles are the common choice for both new homes and reroofs. They stand up to wind better than 3-tab, hide small dips in the deck and usually last longer. A sample board viewed outside, next to the siding, is the best way to choose a color.

Asphalt Shingle Roof Installation Cranford, NJ
Asphalt shingle roof installation is standard work, but the quality varies a lot from one crew to the next. The shingles rarely fail first; the edges, nails and flashing do. It is fair to ask which underlayment and ice barrier will go on and where.
A new asphalt roof in Cranford is usually installed in one to three days once the deck is ready. Shingles seal best in warm sun, so roofs installed in cold weather are often hand sealed along the edges. Rain delays are normal because the deck has to stay dry.

Roofs in this climate
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder 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. That is why roof repair in Cranford is busiest after a hard winter and before the next one.

Shingle Roof Installation FAQ
What kind of underlayment should go under shingles?
Under the shingles sit drip edge, a self-adhering ice barrier in the leak-prone areas, a full layer of underlayment and starter shingles. Synthetic underlayment has largely replaced felt because it is lighter, stronger and less likely to wrinkle or tear. Check that the shingle instructions and local code are both followed.
How steep does a roof need to be for shingles?
The usual minimum for shingles is a pitch of 2 in 12. Low slopes from 2 in 12 up to 4 in 12 need extra underlayment. Flatter sections are roofed with a membrane instead.
How many nails should each shingle have?
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.
Can shingles be installed in cold weather?
Shingles go on best in mild, dry conditions. Winter installs are possible, but the shingles need gentle handling and the sealant may not bond until warmer days. Whatever the season, the deck has to be dry.
Which is better, 3-tab or architectural shingles?
3-tab shingles are a single flat layer with cutouts, while architectural shingles are two laminated layers. The thicker build gives architectural shingles better wind resistance and a longer life, and many lines no longer offer 3-tab. A roofer can help weigh the two for your house.
