Roof Replacement

Replacement may be appropriate when a roofing system has widespread deterioration, recurring failures, extensive damage, or significant age. Alte Roofing & Siding installs GAF roofing systems, including architectural shingles, as part of a full roof replacement.

A complete replacement involves more than installing new shingles. Depending on the property, the work may include removing existing roofing, evaluating the roof deck, installing protective layers, addressing flashing details, and ensuring appropriate ventilation. The objective is a complete roofing assembly rather than covering visible problems.

Roof Repair & Leak Detection

A damaged area does not automatically mean the entire roof needs replacing. When the surrounding roofing system remains in good condition, localized problems can often be addressed through targeted roof repair. Common concerns include:

• Missing or damaged shingles
• Roof leaks and water intrusion
• Deteriorated or failed flashing
• Wind and storm damage
• Damaged roof penetrations
• Localized deterioration
• Recurring problem areas
• Moisture entering around roof transitions

Storm Damage & Roof Inspections

Severe weather can expose weaknesses that are not obvious from ground level. Wind can lift or damage shingles, heavy rainfall can reveal problems around flashing and penetrations, and winter conditions can contribute to ice-related moisture issues.

After severe weather, signs worth checking include:

• Missing or lifted shingles
• Damaged flashing
• New interior water stains
• Visible impact damage
• Granules collecting around the property
• Damaged roof penetrations
• Sagging areas
• New or recurring leaks

GAF Master Elite® Roofing Contractor

Choosing a roofing contractor involves more than comparing estimates. Alte Roofing & Siding is a GAF Master Elite® certified contractor, an exclusive certification available to a limited percentage of roofing contractors nationwide.

That certification, combined with more than two decades of experience, established manufacturer relationships, and completed roofing projects, gives homeowners more to weigh than price alone.

Residential Flat & Low-Slope Roofing

Some areas of a home — porches, additions, dormers — have roof sections with slopes too low for conventional asphalt shingles.

For qualifying residential applications, Alte Roofing & Siding installs the GAF Liberty™ Self-Adhered Roofing System as part of our residential flat roofing service. It uses an SBS-modified bitumen membrane and is installed without a torch or open flame.

Siding Installation

The roof is only one part of a building's exterior envelope. Alte Roofing & Siding installs James Hardie® fiber cement siding and premium vinyl siding.

Siding helps protect exterior walls from weather while contributing to the overall appearance of the property. The appropriate material depends on the building's design, maintenance preferences, desired appearance, and project requirements.

Seamless Gutters & Gutter Protection

Roof runoff needs to be managed properly. Gutters collect water from the roof and direct it through downspouts away from the building. When drainage components are damaged, blocked, or functioning poorly, water can overflow along the roofline or accumulate around the property.

Alte Roofing & Siding provides seamless gutters and gutter guards. Signs the drainage system may need attention include:

• Overflow during rainfall
• Sagging or separated gutter sections
• Damaged downspouts
• Water collecting near the building
• Excessive debris
• Rust or visible deterioration
• Recurring drainage problems

Windows & Other Exterior Improvements

A property's exterior is made up of several connected components. Along with roofing, siding, and gutters, Alte Roofing & Siding provides replacement windows, so several exterior needs can be handled through one contractor.

We also install GAF Energy solar shingles, which integrate solar technology directly into the roofing system. Because the shingles form part of the roof, the condition and design of the existing roof should be evaluated before installation.

Why Experience Matters When Choosing a Sparta Roofer

Alte Roofing & Siding has served New Jersey since 2000 and has installed thousands of roofs, including documented projects in Sparta. The company is family-owned and has built its reputation on craftsmanship, accountability, and straightforward recommendations.
