Roof replacement, repairs and low-slope systems installed with proper decking, underlayment and flashing.
About this service
A roof only performs as well as the layers under it. We replace and repair roofs with sound decking, correct underlayment, flashing and ventilation so the assembly sheds water for decades.
Your roof is the first line of defense against rain, snow and sun, and most failures start long before a stain appears on the ceiling. Missing flashing, worn underlayment, poor ventilation and damaged decking all shorten the life of the shingles above them. At Avany Contractors we treat a roof as a complete assembly, not a surface.
Every project starts with a full inspection of the roof, attic and flashing details. We check the decking, look for soft spots and water stains, and document the condition with photos. If a repair is the right answer we say so; when the roof is at the end of its life, we explain the replacement scope clearly.
Our crews remove the old roofing, repair or replace damaged decking, and install underlayment, ice-and-water shield, flashing and ventilation before the finished roof goes on. Serving New Jersey and Pennsylvania from our Trenton base, we protect the landscaping, clean the site daily and back the work with our workmanship guarantee.

It depends on the age of the roof and the extent of the damage. A localized leak with sound decking and underlayment can often be repaired, while widespread wear, multiple leaks or failed flashing point to replacement. We inspect first and explain both options.
Most residential roofs are completed in one to three days depending on size, pitch, the number of layers to remove and the weather. Larger or steeper roofs are scheduled in phases so the house stays protected.
Yes. We trace the leak to its source—flashing, valleys, penetrations or failed underlayment—and correct the detail before the new roof goes on. Covering the problem without fixing the cause only delays it.
Free inspection, clear scope and zero pressure. We respond in under 10 minutes during business hours.
