There are 17,107 people in Denville, which has been a township since 1913. The census puts the median build year of its housing at 1964, and that number tells us more about what we will find on a roof here than the address does. Water is the thing to plan around here rather than wind: the county hazard plan puts 6.0% of Denville residents inside the 1% annual-chance floodplain. On a house like that, where the downspouts discharge matters as much as what is nailed to the deck.
Denville: Lake Cottages, Additions and Rooflines That Meet at Odd Angles
About a century ago, Indian Lake, Cedar Lake, Rock Ridge and Lake Arrowhead started out as summer colonies. Many of those seasonal cottages have since been winterized, enlarged and given dormers, so a single Denville house can carry three or four roof planes built in different decades. The township’s census median build year is 1964, but on a converted cottage the original section is often older than that, and its rafters were never sized for a year-round load.
That is why we begin where the additions join the original house. Those seams, the crickets behind chimneys and the short valleys over a dormer are where leaks show up first. Lot setting matters too. Denville sits at 505 feet along the Rockaway River and Den Brook, and the county hazard plan places 6.0% of residents inside the 1% annual-chance floodplain. On low lots, overflowing gutters and downspouts that dump next to the foundation cause as much trouble as the shingles do. Under the oaks around the lakes, a cleaned gutter can fill again within weeks of leaf drop.
If you want to confirm who we are first, both GAF and Owens Corning list certified contractors on their websites, and we are on those lists. Our New Jersey home improvement registration, 13VH10877700, can be checked on the Division of Consumer Affairs site. We also send our insurance certificate ($1M per occurrence, $2M aggregate) before work begins.

How We Handle Denville Roofs
Leaks where an old cottage meets a newer addition
Two roof planes that were built years apart rarely tie together cleanly. Common faults are missing step flashing at the side wall of an addition, a low-slope section covered in shingles that need a steeper pitch, and a valley that drains straight onto the older roof. We fix the junction properly instead of caulking over it. See roof repair.
Gutters on lots close to water
With part of the township in the floodplain, a wet ceiling is not always the roof. Water can come over a full gutter, back up under the first course in an ice dam, or rise from the ground. We check all three before giving you a price, and we can re-hang, resize or guard gutters so roof water ends up well away from the house.
Full replacement on a house with several roof sections
When a Denville roof is replaced, each section is assessed separately: deck condition, pitch, and whether there are already two layers on it (New Jersey code R908.3.1 allows no more than two). We add ice-and-water membrane in valleys and along the eaves, and flash every wall where an addition meets the older house. See roof replacement.
Permits
On a detached one- or two-family house, putting on a new roof covering counts as ordinary maintenance under N.J.A.C. 5:23-2.7, so you normally do not need a construction permit. Townhouses and condominiums are the exception. The township Building Department is in the municipal building at 1 St. Mary’s Place, 973-625-8300.
Denville Roof Questions, Answered
How quickly can someone come out to Denville?
The township is about 3.5 miles from our Rockaway office, roughly seven minutes by US-46 and I-80 east. Someone answers 973-960-7921 at any hour. If a ceiling is dripping, we make the area safe and dry first, then price the full repair once the roof can be inspected properly.
Our lake house was a summer place. Does the roof need anything special?
Often it does. Former seasonal cottages tend to have shallow pitches, small overhangs and attics with almost no ventilation, and heating them all winter brings ice dams and condensation. A roof inspection looks at the framing and ventilation as well as the shingles, so you know if the old section needs more than a new surface.
When should gutters be cleaned around the lakes?
On wooded lots, once after the leaves have finished falling and again in spring is a sensible minimum. Some lots need more. If yours overflow every year, our maintenance visits can include cleaning and a check of every outlet.
We also serve neighboring Mountain Lakes, Rockaway Township and Parsippany-Troy Hills, as well as all of Morris County. For a free written estimate in Denville, call 973-960-7921 or use the contact page.
