Hillsborough Housing Styles & Common Exterior Needs
1980s and 1990s colonials along Amwell Road and Route 206 frequently exhibit granule loss, cracked shingles, and deteriorating rubber pipe boots. Upgrading to a GAF Timberline HDZ roof system with Cobra ridge ventilation and synthetic underlayment restores complete weather protection.
Aging pressure-treated wood decks built during original construction are now 25 to 40 years old, suffering from loose railings, rotting joists, and unflashed ledger boards. Replacing aging structures with low-maintenance Trex or TimberTech composite decking provides decades of hassle-free outdoor living.
Near the Sourland Mountain
Homes on the higher, wooded ground toward the Sourlands deal with more shade, more moisture and more tree debris than homes in the open developments. For these properties we recommend algae-resistant shingles, gutter guards, and a close look at any trees overhanging the roof before the new one goes on.
Hillsborough Township Permits & HOA Compliance
All structural, deck, siding, and roofing projects require permits through the Hillsborough Township Building Department at 379 South Branch Road. Double D Construction manages the permit filing, footing inspections, and final reviews.
Many Hillsborough subdivisions have strict HOA covenants governing shingle colors, siding shades, and deck footprints. We provide specification packets and material samples to make HOA board approvals seamless.

Frequently Asked Questions
My Hillsborough home was built in the late 1980s. Does it need a new roof?
If your roof is original or over 20-25 years old, it likely shows granule loss, curling shingles, or boot degradation. Double D Construction provides free local inspections to assess remaining roof life.
Are permits required for building a composite deck in Hillsborough?
Yes. Hillsborough Township requires building permits and footing inspections for all new and replacement decks. We handle all municipal filings and inspection scheduling for you.
Do you serve Neshanic and Belle Mead?
Yes. Double D Construction works across all sections of Hillsborough Township, including Neshanic, Flagtown, Belle Mead, and the Sourland Mountain region.
Should I trim trees before my roof is replaced?
If branches touch or hang over the roof, trimming them first protects the new shingles and helps the roof dry out after rain.
