Roof Replacement & New Roof in Allendale, NJ

Tear-off & re-roof for Allendale's mid-century homes.

In detail

The largest single layer of Allendale's housing stock went up in the postwar decades — the 1950s and '60s ranches, split-levels and Colonials that fill streets like Crest Drive and West Allendale Avenue. Many of those roofs are now on their second or third generation of asphalt shingle and genuinely due for a full replacement. Alongside them sits a newer wave of custom rebuilds. Roof replacement in Allendale (07401) is less about a single ideal material than about matching the material to the house, the budget, and how long you plan to stay.

Johannemann & Sons handles the full re-roof: tear-off and disposal, deck inspection and repair, ice-and-water and underlayment, flashing renewal, and finish in the material you choose. Every installation is manufacturer-warrantied and staged to stay weather-tight each night.

Materials

Choosing the right material for your Allendale home

The mid-century roofs that dominate the borough were originally shingled, and most owners re-roof in shingle again — but a replacement is also the moment to reconsider. Here is how the main options compare on an Allendale home:

01

Premium architectural shingle

The practical default: 30-50 year systems that suit the ranch and split-level stock and carry the strongest cost-to-lifespan ratio.

02

Standing seam metal

Copper, zinc, aluminum, or coated steel for a 40-100+ year roof that sheds snow and resists ice dams — a strong fit for both contemporary rebuilds and low-slope mid-century wings. See standing seam metal roofing.

03

Cedar shake

Hand-split or taper-sawn, Class A fire-treated, for the Colonial and Cape homes where a natural look matters. See cedar shake roofing.

04

Natural or synthetic slate

The longest-lived option (75-150 years for natural), for the older and higher-end homes; synthetic slate delivers the look at a fraction of the weight where structure is a concern. See slate roofing.

The work

What a full tear-off and re-roof involves

Tear-off to the deck

We strip the old shingle completely rather than layer over it — the only way to inspect the sheathing and reset the flashing correctly.

Deck inspection and repair

Soft, delaminated, or rotted sheathing is replaced before anything new goes down.

Weatherproofing layer

Ice-and-water membrane at the eaves, valleys, and penetrations; synthetic underlayment across the field.

Flashing renewal

New step, counter, valley, and chimney flashing in matched material — never reused from the old roof.

Finish and cleanup

Your chosen material installed to manufacturer spec, a full magnetic nail sweep, and landscaping protection throughout.

What it costs

Roof replacement cost tiers in Allendale, NJ

A new roof on a typical Allendale ranch or split-level is often simpler and more affordable than the borough's larger customs, because the geometry is straightforward. As a rough guide, installed: premium architectural shingle runs about $7-$12 per square foot; standing seam metal varies by metal — coated steel $12-$18, aluminum $14-$22, zinc $18-$30, and copper $25-$50+; cedar and natural slate sit at the top. Every material side by side, with whole-roof totals, is in our roof replacement cost guide. A whole mid-century re-roof in architectural shingle commonly lands in the low-to-mid five figures, while a complex custom roof in metal or slate can reach $80K-$120K+. We itemize every line in the written quote.

Specifics

How long a replacement takes

An architectural-shingle re-roof takes days. Standing seam metal, cedar and slate take longer, because the detailing is slower and much of it is cut and formed on site. Natural slate and copper are also ordered for the job, so we schedule the crew against the real delivery date and keep the house weather-tight every night in between.

Questions
How much does a new roof cost in Allendale, NJ?

A full re-roof on an Allendale home typically runs from the low five figures for a straightforward mid-century ranch or split-level in architectural shingle, up to $80K-$120K+ for a large or complex custom in metal or slate. The biggest cost drivers are material, roof size, and geometry. Every quote is itemized in writing.

Which roofing material should I choose for my Allendale home?

For most of the borough's ranch, split-level and Colonial stock, premium architectural shingle offers the best balance of cost and lifespan. Standing seam metal is worth the premium if you want 40-100+ years and better snow and ice-dam performance; cedar and slate suit the older and higher-end homes. We walk you through the trade-offs for your specific roof.

Do you tear off the old roof or install over it?

We tear off to the deck. Layering new shingle over old hides deck rot, adds dead load, shortens the new roof's life, and prevents proper flashing — so a full tear-off is standard on our Allendale replacements. It also lets us inspect and repair the sheathing before anything new goes down.

How long does a roof replacement take in Allendale?

An architectural-shingle re-roof takes days; standing seam metal, cedar and slate take longer because of the hand-detailing involved, and natural slate or copper is ordered for the job. Your written estimate gives the schedule for your roof, and the house is closed weather-tight every night.

Will a new roof help when I sell my Allendale home?

It helps. Allendale is a family-oriented, move-in-driven market, and buyers and inspectors both scrutinize roof age. A recent, warrantied roof removes a common negotiating point and signals a well-kept home — though we would never install one on that basis alone if a repair still makes sense.
