Union’s housing stock is unlike anywhere else in Union County. The township’s signature mid-century split-levels and Cape Cods, built during the post-WWII suburban boom from 1945 to 1965, now sit at 60-80 years old and are entering their second or third shingle replacement cycle. These homes combine steep main-roof pitches with low-slope garage and addition sections, creating chronic valley and pitch-transition failure points that are the signature roofing problem across Union. A contractor who doesn’t understand this local pattern will quote you a standard reroof and miss the real trouble spots. We don’t.
Our crews know the difference between a Vauxhall Road split-level and a Burnett Avenue Cape Cod. We know where the original builders cut corners on flashing, where the nor’easter wet snow piles up, and where the summer UV cooks the low-slope sections first. That knowledge saves Union homeowners from callbacks, interior damage, and the kind of slow leak that rots a family room ceiling before anyone notices the stain.

Our Roof Replacement & Installation Services in Union
Full Roof Replacement
A full roof replacement on a Union split-level is a different job than on a ranch or colonial. The multi-plane rooflines, the low-slope garage section, the original dormers and additions layered over decades - each junction is a potential failure point. We strip to the deck, inspect every square foot of sheathing, and replace rotted OSB or board sheathing before the new roof goes on. Most full replacements in Union take two to three days, depending on the complexity of the roofline and whether we find hidden damage in the garage-to-main-roof valley.
Our Roof Replacement & Installation team handles everything from permit pull to final cleanup. We photo-document the deck condition, the flashing details, and the finished work. You see what we see.

New Construction Roofing
New builds in Union are less common than reroofs, but when they happen - additions, teardowns, infill on Morris Avenue corridors - we install from the rafters up. We spec proper ventilation from day one, which is critical in Union’s humid summers and freeze-thaw winters. A new roof built right the first time won’t need the remedial fixes we so often perform on 1950s originals.

Asphalt Shingle Installation
Asphalt shingles remain the right choice for most Union homes, but the grade matters. The original 3-tab shingles on your Cape Cod’s garage section were never designed for a 2/12 pitch in a nor’easter zone. We install architectural and designer shingles from GAF and CertainTeed with proper underlayment systems, and we always recommend ice-and-water shield at the eaves and in valleys. For the low-slope garage sections common on Union’s splits, we typically specify modified bitumen or a low-slope membrane instead of standard shingles - it’s the difference between a 12-year life and a 25-year life.

Metal Roofing
Metal roofing makes sense for some Union homeowners, especially those staying put for the long haul. The upfront cost runs higher - typically $15,000-$28,000 for a Union split-level - but the lifespan doubles or triples. We install standing seam and metal shingle systems from quality manufacturers, with proper fastening for Union’s wind exposure. Metal sheds snow faster than asphalt, which matters on those low-slope garage sections where ice dams form first.

Flat Roofing
Flat and low-slope roofing is where Union’s housing stock demands real expertise. The 2/12-3/12 pitch over your attached garage isn’t truly flat, but it’s flat enough that standard shingles fail. We install modified bitumen systems, TPO, and EPDM with full ice-and-water shield underlayment. The key detail is the transition where the low slope meets the steep main roof - this is where original construction so often lacked counter-flashing, and where we spend extra time getting the flashing right.

Tile Roofing
Clay and concrete tile are less common in Union’s mid-century neighborhoods, but we install them where appropriate - typically on newer homes or substantial renovations where the structure can handle the weight. We assess load capacity carefully; many of Union’s 1950s frames weren’t designed for tile.

Trusted Brands We Service in Union
We’re authorized installers for seven leading manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Union’s climate and housing stock, we most often specify GAF Timberline architectural shingles for steep-slope sections and GAF Liberty SBS modified bitumen for low-slope transitions. We stock common accessories locally, which means faster turnaround when your job needs a specific ridge vent, starter strip, or valley liner. No waiting two weeks for a special order while your old roof leaks through another nor’easter.
Common Roof Replacement & Installation Problems We See in Union Homes
- Corroded step flashing at garage-to-roof valleys. The low-slope section over your attached garage meets the steep main roof at a critical junction. Original construction often used simple step flashing with no counter-flashing. After 60-80 years, that flashing corrodes, and water runs straight into your finished living space below. We find this on nearly every 1950s split-level in Union.
- Aging OSB and board sheathing delaminating under ice dams. Union’s shallow roof overhangs don’t give snow and ice much room to shed before it backs up. Nor’easter wet snow melts, refreezes at the eave, and lifts the shingles. Do this enough times, and the sheathing beneath rots. We replace damaged decking as part of every reroof, not as a surprise add-on.
- Original 3-tab shingles failing prematurely on low-slope garage sections. Standard 3-tab shingles need a 4/12 pitch or steeper to shed water properly. On your 2/12 garage roof, they pond, crack, and leak years before the main roof shows wear. Union’s heavy UV and freeze-thaw cycling only accelerates the failure.
- Ventilation deficiencies trapping summer heat and winter moisture. Many Union homes were built with minimal or no ridge venting, relying on gable vents alone. In summer, attic temperatures push 150°F, cooking the shingles from below. In winter, moist air condenses on the sheathing. We assess and correct ventilation on every replacement.
Pricing for Roof Replacement & Installation in Union, NJ
Here’s what a typical roof replacement costs in Union’s market:
| Service | Typical Range in Union |
|---|---|
| Asphalt shingle reroof, standard split-level (1,800-2,400 sq ft) | $8,500-$14,000 |
| Asphalt shingle reroof, complex multi-plane Cape Cod | $10,500-$16,500 |
| Low-slope garage section, modified bitumen replacement | $2,800-$5,500 |
| Metal roof, standing seam, full replacement | $15,000-$28,000 |

| Ice-and-water shield upgrade (full low-slope section) | $800-$1,800 |
What moves you within these ranges? Roof complexity, deck condition, accessibility, and the number of layers to strip. A split-level with two dormers, a garage addition, and original board sheathing that needs replacement will run higher than a simpler roof on sound decking. We price this out line by line before we start. No surprises, no upsells mid-job.

FAQs - Roof Replacement & Installation in Union
The fix is replacing the low-slope section with a proper modified bitumen membrane and installing continuous counter-flashing at the transition. On a 1955 split-level on Vauxhall Road, we found the garage-to-roof valley had corroded step flashing and no counter-flashing, allowing years of hidden rot into the finished family room below. We replaced the entire low-slope section with GAF Liberty SBS modified bitumen and ice-and-water shield, then reflashed the transition with continuous copper cleats - a solution that handles Union’s freeze-thaw cycles far better than the original build. Call (844) 563-1816 and we’ll inspect your valley at no charge.
Upgrade. Standard 3-tab shingles are not rated for the 2/12-3/12 pitch common on Union garage sections, and they fail prematurely under our UV and freeze-thaw cycling. We recommend GAF Liberty SBS modified bitumen or a comparable low-slope membrane for garage sections, with full ice-and-water shield underlayment. The material cost runs higher, but you’ll double the lifespan and eliminate the leak risk. We can quote both options so you see the difference.
Yes. Most 1950s Union homes were built with inadequate attic ventilation, often just gable vents with no ridge venting. A modern roof replacement should include a balanced system: ridge vent at the peak, soffit venting at the eaves, and proper baffles to keep airflow clear. Without this, summer attic heat cooks the shingles from below and winter moisture condenses on the sheathing. We assess ventilation on every Union replacement and include corrections in our estimate. Call (844) 563-1816 for specifics on your home.
Install ice-and-water shield across the full low-slope garage section and at least six feet up the main roof eaves, improve attic insulation to reduce heat loss, and ensure proper ventilation so the roof deck stays cold. Union’s shallow overhangs make ice dams nearly inevitable in heavy wet snow; the question is whether the backup finds a path into your house. The right underlayment system, properly lapped and sealed, is your best defense. We specify this on every Union reroof.
Two to three days for most Union split-levels, assuming standard asphalt shingles and no major deck repairs. Day one: tear-off, deck inspection, and repairs. Day two: underlayment, flashing, and shingle installation. Day three: details, cleanup, and final inspection. Complex multi-plane roofs with multiple dormers and additions may run to four days. We don’t rush the flashing work at the garage-to-roof transitions; that’s where the leaks start, and we’d rather take the time than come back. Call (844) 563-1816 for a timeline on your specific roof.
