Allentown experiences extreme seasonal shifts—from humid, storm-heavy summers to freezing winters with frequent snow loads. Standard roofing installations often fail prematurely in this region due to two specific environmental factors:
Freeze-Thaw Cycles ──> Ice Dam Formation ──> Sub-Roof Water Intrusion
Summer Humidity ──> Poor Attic Venting ──> Premature Shingle Granule Loss


When snow melts and refreezes at the eaves along Allentown’s tree-lined streets, water backs up under standard shingles. We install self-adhering ice and water barriers extending at least 24 inches past interior wall lines to stop moisture intrusion permanently.
Combating Central Jersey Humidity
Summer heat trapped in poorly ventilated attics bakes shingles from the underside, causing blistering and curling. Our installations include balanced ridge-and-soffit ventilation systems conforming to guidelines from the National Roofing Contractors Association (NRCA) to extend shingle lifespan and lower household cooling costs.
At Tri-State Window and Siding, we have a wide range of window designs that elegantly mix appearance and utility to improve houses all across Edgewater, New Jersey. Discover our selection of reasonably priced window solutions:

Our double-hung windows are classic and adaptable; their two moveable sashes allow for great ventilation and simple cleaning. Their classic style accentuates both modern and conventional houses really nicely.

Designed for all-weather ventilation, awning windows extend outward from the bottom to let fresh air in while shielding rain out. Their elegant and understated form makes them perfect for atop more significant fittings or little areas.

With our bay and bow windows, which stretch outward to provide extra inside space and panoramic views, you will improve the curb appeal of your house. These windows are ideal for designing comfortable, light-filled corners in your house.

Hinged at the side and open outward with a crank handle, stylish and useful casement windows maximize airflow and unhindered views. Their contemporary design guarantees simple running and a neat look, ideal for modern houses.

We are fans of Tristate. We had windows replaced by them last year and this year they replaced another window, a patio door and our siding. There were a few complications Tristate came across with the siding manufacturer, but they overcame their obstacles and actually provided us a more superior siding product. Anthony, Marcelo and Joy from Tristate provided us with consistent communication throughout the process. We will continue to use Tristate for our future projects!Posted on Google Michael SchiffTrustindex verifies that the original source of the review is Google. Owner is very attentive and responsive.

Find answers to common questions about window replacements and siding installation, maintenance, and service areas.
Project pricing is calculated based on exact roof pitch, square footage (measured in roofing squares), existing layer tear-off requirements, rotted CDX plywood replacement, and chosen underlayment upgrades. For an exact on-site measurement and transparent pricing breakdown, schedule through Tri-State Window and Siding Free Estimates.
Yes. Both the Borough of Allentown and Upper Freehold Township enforce the New Jersey Uniform Construction Code (UCC). Permits are filed through the local construction office via the Allentown NJ Construction Portal. We pull and manage all required municipal permits and coordinate final inspections.
Ice dams occur when heat escapes from under-insulated attics, melting snow on upper roof planes. The run-off hits colder roof eaves near gutters and freezes into a ridge, backing water under shingles. We prevent this by combining R-38+ attic airflow with self-adhering ice barriers.
Key indicators include excessive shingle granules in gutter downspouts, curled or cracked shingle tabs, dark streaks caused by Gloeocapsa magma algae, rusted step flashing around brick chimneys, and spongy decking underfoot.
While the New Jersey Residential Code (Section R908.3.1) allows recovery under narrow constraints, we advise against overlays. Overlaying traps heat, adds structural load, conceals rotted wood decking, and often compromises manufacturer warranties.
Heavy-weight architectural shingles with deep shadow lines (such as GAF Camelot, Slateline, or Timberline UHDZ) mimic hand-split wood shake and slate, maintaining historic character under NJ Historic Rehabilitation Code guidelines while delivering modern Class A fire resistance.
Most residential roof installations in Allentown are completed within 1 to 2 business days, including complete tear-off, decking repairs, shingle installation, and magnetic nail cleanup.
Yes, if the damage is caused by sudden perils such as wind uplift, fallen tree branches from severe Nor’easters, or hail strikes. We document physical damage, provide insurance-compliant estimates, and meet with adjusters on-site.
Without balanced ridge and continuous soffit vents, summer attic temperatures can exceed 140°F, radiating heat downward and forcing air conditioners to run continuously. A properly ventilated roof can lower attic temperatures by up to 30°F, protecting HVAC systems and complementing our energy-efficient window installations.
High humidity and shade from dense local trees foster airborne algae (Gloeocapsa magma). We install shingles embedded with copper and zinc granules that release microscopic ions during rainfall, preventing organic staining for up to 25 years.
Traditional asphalt-saturated tears easily during high winds and absorbs moisture over time. We install 100% woven synthetic underlayment, which provides up to 25 times more tear resistance, repels water, and creates an impermeable barrier beneath the shingles.
We use protective tarping systems, plywood wall shielding for siding and windows, and rolling industrial magnetic sweepers that comb flowerbeds, walkways, and driveways multiple times to collect all nails and metal debris.
