A proper Denville roof replacement is a complete system, not just the shingles you see. We tear off the old roof to the deck, inspect and replace any rotted sheathing, and rebuild with new underlayment, ice-and-water shield, flashing, drip edge, ventilation, and the surface you choose.

When It Is Time to Replace Your Denville Roof
Age is the first signal, since an asphalt shingle roof in Denville is typically due around 25 to 30 years. If you see several of these, a free inspection will confirm whether replacement is the better value.
- The roof is 20+ years old and repairs are becoming frequent
- Widespread curling, cracking, or balding shingles
- Large amounts of shingle granules in the gutters
- Multiple leaks or staining in different areas
- A sagging roofline or visible deck damage
- Daylight or moisture throughout the attic

What Roofing Materials Do You Install in Denville?
We install architectural and three-tab asphalt shingles, standing-seam and other metal roofing, tile, and flat-roof systems such as EPDM, TPO, and modified bitumen, matching the material to your property and budget.
Should I Replace or Just Repair My Denville Roof?
