Roofing for Knowlton homes
Knowlton covers about 24.7 square miles of Warren County and has roughly 1,160 homes and apartments. That’s a well-established housing stock, with a typical home dating to around 1980. Most homes are owner-occupied, so many of the roofs we see in Knowlton belong to families planning to stay for years, which is exactly when a properly built roof pays off.
Housing figures: U.S. Census Bureau, 2019–2023 American Community Survey 5-year estimates.
Book before the snow flies
In Knowlton, the best time for repairs or a replacement is late summer and early fall, before winter brings snow loads and ice dams. A roof that goes into winter sound comes out of it sound.

What Knowlton homeowners should know
Based on the age and type of homes in Knowlton and the weather it gets.
Homes from the 1970s and ’80s
The median home in Knowlton was built in 1980. Many homes from this period are on their second roof, and some still have original skylights, vents, and flashing that have outlasted their useful life. Older plywood decking from this era can also soften where leaks went unnoticed, so it’s checked during any tear-off.
Large lots and outbuildings
Knowlton is spread out, with fewer than 50 homes per square mile. Larger properties often have detached garages, sheds, and barns with their own roofs, along with long driveways that need planning for material deliveries and debris removal.
Snow, cold, and ice dams
Knowlton gets colder, snowier winters than much of New Jersey. Ice dams at the eaves, heavy snow loads, and freeze-thaw cycles are the main threats, so an ice barrier at the eaves and in valleys, plus good attic ventilation, matter on any new roof.

Roof repair in Knowlton
Most roof leaks in Knowlton start small: a cracked pipe boot, a lifted shingle, or flashing that has pulled away from a wall. We trace the water back to where it actually gets in, which isn’t always right above the stain, and fix the cause instead of smearing sealant over the symptom. Typical repairs include replacing damaged or missing shingles, resealing or replacing flashing, swapping out worn pipe boots and vents, and cutting out soft decking so the repair sits on solid wood.
Roof replacement in Knowlton
New roofs start at $6,500, and every Knowlton replacement we do includes the layers you don’t see: tear-off of the old roofing, decking repairs, underlayment, new drip edge and flashing, and ridge ventilation, topped with the shingle color and style you choose. Many single-family roofs are finished in one to a few days, and we clean up before we leave.
Storm damage & 24/7 emergency roofing
When a roof emergency hits in Knowlton, our first goal is stopping the water. We tarp or temporarily repair the damaged area, then come back to make a proper repair. Our written estimate describes the damage and the work, which helps if you’re filing an insurance claim. Call (201) 773-6635 any time, day or night.
Skylights, flashing & ventilation
The details make or break a roof. On Knowlton homes we pay close attention to skylight flashing, valleys, step flashing along walls, and pipe boots, the spots most likely to leak. When a roof is replaced, it’s also the best time to improve attic ventilation with ridge vents or solar attic vents.

email info@allprosnj.com.
Do you offer roof repair and replacement in Knowlton?
Yes. Knowlton is part of our Warren County service area. We handle roof repair, full roof replacement, storm damage repair, and 24/7 emergency calls, with free on-site estimates.
How old are the homes in Knowlton?
According to U.S. Census Bureau estimates, the median home in Knowlton was built in 1980. About 36% of homes were built before 1960 and about 9% since 2000. Age matters for roofing because it affects the decking, the number of old layers, and the details that need flashing.
What should I check on a 1970s or ’80s home in Knowlton?
Look at skylights, vents, and flashing, which are often original and past their prime, and watch for soft spots in the decking. If the roof itself is 20+ years old, an inspection will tell you whether it’s time.
How much does a new roof cost in Knowlton?
Complete roof replacements start at $6,500. The price depends on the size and pitch of your roof, layers to remove, decking repairs, and materials. New roofs are currently up to 20% off, and we’ll beat any written quote.
Can you just repair my roof instead of replacing it?
Often, yes. If the problem is limited to one area and the rest of the roof is sound, a repair makes sense. We’ll tell you honestly which option is the better value for your Knowlton home.
Do you offer any discounts?
Yes. New roofs and roof repairs are currently up to 20% off, veterans receive 10% off, and we’ll beat any written quote.
