Roof replacement begins with an inspection and photos, followed by a written scope and price.
For roof replacement in Trenton and 12 towns across Mercer, Burlington, Camden and Gloucester counties, Roofers Hotline takes one call at (855) 512-1072. The line is answered around the clock, and you get a written estimate before work starts.
According to NOAA storm records, Mercer County logged 13 hail events of one inch or larger since 2015, so storm repair is routine work here.
With a median build year of 1950, many local roofs carry more than one covering, and all of it comes off down to the deck. Old material is hauled away, so the new roof starts on a clean surface. Call Roofers Hotline to have the layers counted and written into your estimate.
About 83% of the metro's homes were built before 1980, so the boards under the shingles have had decades of moisture and temperature swings. Once the roof is stripped, the deck is checked, and soft sections are replaced before anything new goes on. Call to get that decking line priced in writing.
The nearest NOAA station averages about 109 freeze days a year, and snowmelt can back up at the eaves. Ice-and-water shield, underlayment and drip edge go in before the new covering to keep that water out of the house. Ask for these layers by name on your written estimate.
The metro's county record shows 13 hail events of one inch or larger since 2015, with hail up to 1.5 inches, so the covering and how it is fastened matter. Shingles, metal or tile are installed with manufacturer-rated fasteners. Call to compare the options in your written estimate.

Roofers Hotline handles roof replacement in Trenton, and the age of the homes here is the first reason to call. By Census estimates for 2019 to 2023, 83% of the metro's homes were built before 1980, against 66% county-wide, and the median home dates to 1950. Many of those roofs are already on a second covering or more, so a worn roof here is often a replacement question, not a patch job. Call Roofers Hotline to book the roof inspection and get a written estimate before any work starts.
Trenton's housing is older than the rest of the county, and that changes how a replacement goes. A large share of homes here, 40.8% by Census estimates, predate 1940, the slate and tile era, so the visit often turns up several old layers and decking that has aged under them. The written estimate lists the tear-off, any decking that has to be replaced, and the new covering as separate lines, so you can see what the age of the house adds. Call to schedule the inspection.

Trenton's county record includes 13 hail events of one inch or larger and 8 tornadoes in NOAA's storm records since 2015, so two signs deserve a look after a storm. Widespread granule loss on shingles past 20 to 25 years shows up as grit in the gutters, and sagging deck lines are visible from the street. Photograph both from the ground and do not climb the roof. Then call Roofers Hotline to book an inspection.
