Roof inspection starts with the problem found and photographed, then the scope and price in writing before any work starts.
Roofers Hotline books roof inspection in Trenton and 12 towns across Mercer, Burlington, Camden and Gloucester counties from one number, (855) 512-1072. Calls are picked up 24/7, and no work starts without a written estimate.
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.
Every slope gets looked at, by walking the surface or by drone, so nothing is judged from the ground alone. With 83% of local homes built before 1980, older shingles and past patches are common, and the survey records them with photos. Call to book the survey of your roof.
Flashing, vents, chimneys, valleys and the ridge are where leaks usually start. The metro gets 47.4 inches of precipitation a year in the 1991 to 2020 normals, so these joints carry a lot of water. You get each weak spot noted in the report. Call to have them checked.
From inside the attic, the check looks for damp wood, poor airflow and daylight coming through the roof deck. The metro sees 108.9 freezing days a year in the 1991 to 2020 normals, and moisture in a poorly vented attic can freeze and thaw. Call to book the attic check.
Gutters and downspouts are checked for clogs, sagging and hail dents, since the county has recorded hail up to 1.5 inches. Water that cannot drain backs up under shingles and at the fascia. You get any drainage problem listed in the report. Call to include the gutters in your inspection.
The job for roof inspection runs from the first call to the scheduled work, step by step.
Half the homes in Trenton were built before 1980, and then some: 83% by Census estimates for 2019 to 2023, with a median build year of 1950. Roofs on houses that old carry decades of patching, worn flashing and thin attic ventilation. Roofers Hotline books roof inspection here so you learn the condition of every slope before a small problem turns into a ceiling stain. Mercer County logged 13 hail events of one inch or larger since 2015, so a roof that has not been checked recently is worth a look. Call Roofers Hotline to book the inspection and get a written report.
Trenton's housing differs most from the county picture. Across the county 66% of homes were built before 1980, but here the share is 83%, and only 35.9% of homes are owner-occupied. That mix means many roofs have gone years without a documented check, and landlords and buyers often need a clear written record. The visit covers flashing, valleys and the attic as well as the shingles, because older framing and ventilation fail in ways a ground view misses. The written estimate then gives a repair-or-replace opinion with photos. Call to schedule the inspection.

Hail up to 1.5 inches has been recorded in the county, and eight tornadoes were logged since 2015, so two signs matter most here: a roof older than 15 years with no recent check, and any roof after a hail or wind event. Look from the ground for missing shingles, dented gutters or granules in the downspouts, and photograph what you see. Do not climb up to look. Call Roofers Hotline and book the inspection so the damage is documented before the next storm.

Questions
Book an inspection whenever a roof is older than 15 years and has had no recent check, and again after any hail or wind event. The metro's median home was built in 1950, so many roofs here are well past that point. Call Roofers Hotline to schedule the visit and ask for the written report.
Yes. The visit includes the attic for moisture, ventilation and daylight, plus the gutters and drainage. The metro averages 108.9 freezing days a year in the 1991 to 2020 normals, so water and ice are real concerns. Call Roofers Hotline to book the full inspection.
