What Drives Roofing Costs in the Highlands

No one can give you a fair figure for roof work without seeing the roof. Two jobs that sound the same can be very different once a roofer is up there. What we can do is explain what drives the cost of roofing in Hackettstown and the surrounding townships, so you can understand an estimate and compare them fairly.

The roof itself

• Size. Roofers measure in squares - 100 square feet of roof surface. Steep roofs have far more surface than the floor plan suggests.
• Pitch. Steep roofs, common on older homes here, take more time and safety equipment.
• Complexity. Dormers, valleys, turrets, porches and multiple chimneys add flashing and labor.
• Height and access. Three-story Victorians, hillside lots and tight driveways all add time.

What's underneath

• Layers. Each old layer that has to come off adds labor and disposal.
• Decking. Rotted boards near chimneys and eaves are common on older homes, and plank decking may need new sheathing. Nobody knows exactly how much until the old roof is off, so ask how it will be handled.
• Ice dam damage along the eaves from past winters.

Material

Architectural asphalt shingles, metal and slate are very different investments with very different lifespans. Repairs to slate and metal need specialized skills and materials. Upgrades like extra ice and water shield, ridge ventilation and full manufacturer systems also change the scope.

Climate-specific work

In this part of New Jersey, a proper roof includes more protection against ice: ice and water shield along the eaves and valleys, crickets behind wide chimneys, balanced attic ventilation and sometimes snow guards on metal roofs. These are worth including - they're what keep a roof from leaking in February.

Timing

Emergency work in a storm, or winter repairs with snow and ice on the roof, take longer and are harder than planned work in good weather. Booking repairs and replacements in late spring through early fall is usually easiest, and roofers fill up quickly in the weeks before winter.

Comparing estimates

1. Make sure each covers the same scope: tear-off, decking, ice and water shield, underlayment, flashing, ventilation, material and cleanup.
2. Ask how extra work - rotted boards, chimney repairs - will be priced.
3. Get warranties in writing: materials and workmanship.
4. Check the contractor's New Jersey Home Improvement Contractor registration.
