I have fixed roof leaks on older homes in North Trenton and South Trenton for years. Hot summers here bake asphalt shingles until they crack, then cold winters let water sneak under the edges. Cheap crews often skip new step flashing around chimneys, and that leads to rot inside the attic within one season. A proper repair uses 26-gauge galvanized flashing cut to fit, plus ice-and-water shield under the first course.
Many Trenton houses near Cadwalader Park still have original slate or cedar shakes. These fail where the nails rust out after twenty winters of freeze-thaw cycles. I replace individual slates or shakes instead of the whole roof when the rest is sound. Mercer County requires a permit once you touch more than one square, so we pull that before we start.
Flat roofs on small commercial buildings in East Trenton leak at the drains every spring. Standing water from summer storms sits against the seams and rots the membrane. We cut out the bad section, install a new EPDM patch with 6-inch laps, and add a tapered cricket so water runs off. That job usually takes one day once the old material is out.
Call 609-555-0123 right now if water is coming through your ceiling. We answer 24/7 and can be on site the same day in most cases.
