Roofing in Rossmoor, Monroe Township

For Monroe Township, one local contractor's published 2026 figures put an average 20-square roof at about $10,800 in architectural shingle, and most houses at about $13,000 to $21,000: $11,500 to $16,200 for 1,800 to 2,200 square feet, $14,000 to $19,000 for 2,200 to 2,800, and $18,000 to $25,000 or more past 3,000. Skylights and the chimney move it from there, which is why they are priced separately.

In architectural shingle it is above most Monroe houses' estimated range of $13,000 to $21,000, so ask what is in it. Several skylights replaced at an estimated $900 to $2,200 each can account for a lot of the gap. A New Jersey thread about a $42,000 quote on roughly 2,300 square feet drew the reply that around $26,000 or lower was expected for a high-quality shingle. Ask for the openings line by line.

Not on age alone. Asphalt shingle is generally rated at 15 to 30 years, so twenty is when a roof deserves a proper look, not an automatic replacement. If the shingles still hold their granules, the flashings at the chimney and skylights are sound and the attic is dry, a repair may buy years.

In Monroe, one local contractor's published 2026 figures put a 1,800 to 2,200 square foot house at about $11,500 to $16,200 in architectural shingle. Floor area is only a rough guide: a single-story ranch has far more roof per square foot of floor than a two-story colonial, and two houses of the same size can carry very different numbers of skylights.
