Roofing Companies in Allentown, NJ
Allentown is a small Monmouth County borough of about 1,700 residents on just over half a square mile, bordered by Upper Freehold Township and by Robbinsville in Mercer County. It was incorporated in 1889 from part of Upper Freehold and is named either for Nathan Allen, son-in-law of Robert Burnet, or for William Allen, Chief Justice of colonial Pennsylvania. Nearly the whole village is historic: the Allentown Historic District, listed on the National Register in 1982, covers about 17 acres with 219 contributing buildings, including the Allentown Mill, listed separately in 1978, the Greek Revival Allentown Presbyterian Church of 1837, and the Georgian-style John Imlay House of about 1790. County Routes 524, 526, and 539 meet in town, and Interstate 195 and the New Jersey Turnpike are just outside. The 2010 census counted about 735 homes.
Monarch Roofing & Construction serves Allentown from our office at 168 Humboldt St in East Rutherford, our headquarters. We repair and replace residential roofs, repair chimneys and flashing, and replace gutters and siding.
Roofing in a 219-Building Historic District
With so many contributing buildings in so small an area, a large share of Allentown’s homes are historic. That shapes how roofing work should be planned.
Georgian and Greek Revival houses
Georgian houses usually have simple, symmetrical gable or hipped roofs with chimneys at the ends, while Greek Revival houses often present a gable to the street with a wide cornice. Both depend on crisp, well-kept eaves and cornices for their look, so protecting and repairing that trim is part of any roof job.
Later 19th-century homes
Victorian-era houses in the village may have steeper roofs, dormers, and porches with shallow slopes. Each needs its own flashing plan.
Historic review
Ask the borough whether any local historic review applies before you change roofing material or color, siding, or a chimney on a visible elevation.
Village logistics
On compact village lots, plan dumpster placement and debris control so sidewalks and neighbors stay clear.
Roof Repair in Allentown
We repair leaks at chimneys, dormers, walls, valleys, and vents, replace damaged shingles, and repair rotted roof edges and fascia. See our roofing services.
Roof Replacement in Allentown
We remove old roofing to the deck, repair board or plywood sheathing, and install leak barrier, underlayment, drip edge, new flashing, shingles, and ventilation, protecting cornices and trim throughout.
Chimneys
End chimneys on older houses are prominent and exposed. We repoint with mortar suited to old brick, rebuild crowns and stacks, and replace flashing. See chimney services.
Gutters and Siding
We replace gutters and downspouts, repair fascia and trim, and repair or install siding. On historic houses, ask about gutter profiles that suit the architecture. See siding and gutters.
Choosing a Roof for an Old House
For a historic house, the right shingle is usually one that recedes rather than draws attention. Solid, darker colors and flatter profiles tend to suit Georgian and Greek Revival homes better than heavily shadowed or multicolored blends. Copper or painted flashing can look more appropriate at chimneys than bright aluminum. Keeping the original overhangs and trim profiles, rather than wrapping them in aluminum, preserves the house’s character. These are your choices to make; we will give you samples and an honest opinion.
Hiring Tips
Confirm whether any permit or approval applies from the Borough of Allentown, get the full scope in writing, and check the contractor’s New Jersey home improvement registration with the Division of Consumer Affairs.

Honest Assessments for Historic Village Homes
Honest Roof Assessments. Clear Recommendations. Repairs When Possible. Replacement When Necessary. That philosophy fits Allentown especially well. On an older house, keeping sound original materials and carefully repairing what has failed is often the right first step. When a roof truly needs replacement, we explain exactly why and what the new roof will include.
We are a registered New Jersey Home Improvement Contractor, registration #13VH12036000. Inspections and roofing estimates are free.
Allentown’s Setting and What It Means for Roofs
Allentown sits in the inland farm country of western Monmouth County, so salt air is not a factor, but the village has other conditions worth understanding.
- Mature shade trees. Old village streets are often lined with large trees. Shade keeps roof surfaces damp longer after rain, encouraging moss and dark algae streaks, and falling branches during storms can crack shingles or damage gutters.
- Leaf and seed debris. Valleys and gutters fill quickly in autumn. When a valley clogs, water spreads sideways under the shingles instead of flowing down.
- Freeze-thaw winters. Repeated freezing and thawing loosens mortar in older chimneys and opens small gaps in flashing and sealant.
- Summer storms and wind. Thunderstorms crossing the surrounding open farmland can bring sudden gusts that lift shingle edges, particularly along rakes and ridges.
Roof Leaks in Older Houses
Older homes have more transitions than a typical modern house: end chimneys, dormers, porch roofs at shallow pitches, and rear additions built in different eras. Each transition is a potential leak path. Leak diagnosis starts by tracing water stains in the attic or ceiling back up the slope to where water is actually entering. Common culprits include:
- Deteriorated counterflashing in a chimney’s mortar joints
- Porch roofs that meet the main wall without proper step flashing
- Dormer cheeks where siding and roofing meet
- Plumbing vents added during later renovations
Fixing the real entry point, not just the stain, is what keeps a repair from becoming a recurring problem.
Chimney Flashing on End Chimneys
Many older Allentown houses have masonry chimneys at the gable ends. These chimneys are exposed on several sides and take the full force of wind-driven rain. A sound chimney flashing system includes step flashing layered with the shingles along the sides, a front apron, a cricket or saddle behind wider chimneys to divert water, and counterflashing let into the mortar. When the mortar is crumbling, repointing comes before reflashing so the counterflashing has something solid to hold. Kick-out flashing at the bottom of roof-to-wall joints and well-sealed pipe boots round out the system.
Missing and Damaged Shingles
A few missing shingles after a storm can often be replaced individually if the surrounding shingles are still flexible and well sealed. On an older roof whose shingles have become brittle, lifting neighboring shingles to slip in replacements can crack them, which is one factor in deciding between repair and replacement. After any storm, photograph damage before cleanup. If you file a claim, the insurance company decides what is covered.
What Lies Beneath: Decking, Underlayment, and Edges
On houses of this age, the roof deck may be solid board sheathing rather than plywood. During a replacement, each section is inspected, and boards that are rotted, split, or too soft to hold nails are replaced. Over the deck, a modern system adds:
- Ice and water shield at the eaves, in valleys, and around chimneys and vents
- Synthetic underlayment across the rest of the roof
- Metal drip edge at eaves and rakes to protect wood trim and guide water into gutters
Because cornices and decorative eaves are such a big part of an older home’s character, edge details are installed with care to protect that trim.
Ventilating an Older Attic
Many older houses were built without soffit vents, and later insulation upgrades can block what little airflow existed. Poor ventilation traps heat and moisture, which can shorten shingle life and contribute to ice dams. Options include adding ridge vents, low-profile roof vents, or carefully placed soffit intakes where the eave design allows. The goal is balanced airflow without altering what the house looks like from the street.
Deciding Between Repair and Replacement
Questions worth asking:
- Is the damage confined to one area, such as a chimney or a porch roof?
- Are the remaining shingles still flexible and holding their granules?
- Is the deck solid when walked and probed?
- How many repairs has the roof needed in recent years?
If most answers point toward localized trouble, a repair is usually the sensible choice. If wear is widespread, replacement protects the house, and its historic trim, more reliably.

Asphalt Shingles on a Historic-Style Home
Architectural asphalt shingles come in muted, traditional colors that can complement Georgian, Greek Revival, and Victorian houses. Choosing a color that matches the home’s era and trim is part of the estimate conversation.
Gutter Care in a Tree-Filled Village
Clean gutters at least twice a year, more often under large trees, and make sure downspouts discharge away from old stone or brick foundations, which can absorb water.

Can old board sheathing stay in place under a new roof?
Often, yes. Boards that are solid and properly fastened can remain. Rotted or split boards are replaced before the new roof goes on.
Why does my chimney leak only during wind-driven rain?
Rain blown sideways can get behind worn counterflashing or into cracked mortar that stays dry in calm rain. Inspecting the flashing and masonry together usually finds the gap.
Can moss on a shaded roof cause leaks?
Moss holds moisture against shingles and can lift their edges over time. Gentle cleaning and trimming back overhanging branches help.

A Closer Look at Roofs in Allentown
Allentown’s historic district packs Georgian, Greek Revival, and later nineteenth-century houses into a little over half a square mile. The sections above explain repairs, replacement, chimneys, and flashing. This section looks at the village from a different angle: how its roof shapes behave, how a roof is measured and priced, what to think about when buying or selling an older house here, and how siding fits into the picture.
How Allentown’s Roof Shapes Behave
Each architectural style in the village comes with its own roof shape, and each shape handles weather a little differently.
- Georgian houses usually have simple, symmetrical gable or hipped roofs with chimneys at the ends. Simple planes shed water well and have few valleys, so most problems concentrate at the end chimneys and along the eaves.
- Greek Revival houses often turn a gable end toward the street with a wide cornice below. The broad gable wall faces wind-driven rain, so the rake edges and the cornice beneath them deserve close attention.
- Later nineteenth-century homes tend to have steeper roofs, dormers, and porches with shallower slopes. Every change in pitch creates a joint, and those joints, not the open field of shingles, are where water usually finds its way in.
Knowing which shape you have helps you know where to look after a storm and what an inspector will focus on.
How a Roof Is Measured
Roofers measure in “squares,” with one square equal to 100 square feet of roof surface. A house’s footprint is only the starting point: pitch increases the actual surface area, so a steep roof over the same floor plan holds noticeably more shingles than a shallow one. Valleys, hips, ridges, and starter courses add linear footage of special materials, and complex roofs require extra material for cutting and waste. On older Allentown houses with dormers, porches, and rear additions, careful measurement of each section is what keeps an estimate accurate. When you compare estimates, it is fair to ask how the roof was measured and whether every section, including porch roofs, is included.
Buying or Selling an Older House in the Village
For buyers, the roof is one of the first big-ticket questions on an older home. Ask the sellers how old the roof is, whether it has more than one layer, when the chimney was last repointed or reflashed, and whether there have been leaks. A home inspection will note visible issues, but a dedicated roof inspection can give a clearer picture of remaining life and what repairs may be coming. For sellers, organized records help: the date of the last roof replacement, the shingle product, photos, and invoices for chimney or flashing work. Addressing small, obvious problems such as a cracked vent boot or a missing shingle before listing can keep a buyer’s inspection report shorter.
Siding on Historic Homes
Siding and roofing meet at every wall, and on older houses the two systems age together. Clapboard and other wood siding can rot where it sits close to a porch roof or where gutters overflow onto it. Loose or damaged siding lets wind-driven rain reach the wall sheathing. Where a porch or lower roof meets a sided wall, the siding should end slightly above the shingles, with step flashing behind it. Before changing siding material or color on a visible elevation, ask the borough whether any review applies. Monarch Roofing & Construction repairs and installs siding, and planning siding and roof work together can make the joints between them cleaner.
The Stages of a Roof’s Life
It helps to think about a roof in stages rather than as simply good or bad. In its early years, a well-installed roof needs little more than gutter cleaning and a look after storms. In the middle years, small items such as vent boots, a few shingles, or chimney flashing may need attention, and these repairs extend the roof’s life. In the late years, shingles lose granules and flexibility across most slopes, repairs become more frequent, and planning for replacement makes sense. Knowing roughly where your roof sits in that cycle lets you budget instead of reacting to a leak.
Allentown Roof Planning Questions
What is a roofing square?
A square is 100 square feet of roof surface. Roofs are measured and estimated in squares, adjusted for pitch and complexity.
Does a porch roof count in the estimate?
It should be measured and listed separately if it is part of the work. Ask that every roof section be identified in writing.
What should I ask about the roof when buying an older home?
Ask the roof’s age, how many layers it has, when the chimney was last repaired, and whether there have been leaks. A roof inspection adds detail.
Can siding and roofing be planned together?
Yes. Coordinating them makes it easier to get flashing and siding details right where roofs meet walls.
