Box vents
Damaged louvered vents are renewed before rain gets through the cracks.
Most roof vent leaks in Dumont start at a cracked pipe boot or a broken vent cover, and a roofer can replace the failed part and reseal it into the shingles, and check that each vent is tucked under the shingles correctly. Dial (551) 374-2031 to talk with a local roofer about the vent.
Roof vents and pipe boots are often the first parts of a roof to leak, long before the shingles are worn. The most common failure is the rubber collar on a pipe boot, which dries out and cracks in the sun until rain runs down the pipe into the attic. Other common problems are hail-cracked box vents, ridge vents with backed-out nails and turbines that seize or squeal.
Vents are flashed like any other penetration, and the order matters. The flange should slide under the shingles above it and sit on top of the shingles below, so water runs over it instead of under it. Exposed nails in the flange and missing laps are common reasons a vent leaks even when the part looks fine.
Vent repair also keeps the attic breathing. If an exhaust vent stops working, moisture and heat build up, which can show up as frost, damp sheathing or curled shingles. A replacement should match the ventilation design the house already has.
If the problem goes deeper than it first looked, a Dumont roofer may also recommend roof ventilation or roof leak repair.

Call nowMost vent repairs replace one part and reweave it into the shingles.
The roofer checks each pipe boot, box vent, ridge vent and exhaust hood, plus the attic below them. One failed boot usually means the others are the same age.
The shingles above the vent are carefully lifted by breaking their seal strips, and the nails holding the old flange are pulled. In cold weather, shingles are handled gently because they crack easily.
The new boot or vent goes in with its upper flange under the shingles above and its lower flange over the shingles below. Fasteners are placed under the overlapping shingles, not on the exposed flange.
Shingles around the vent are refastened and sealed down so wind cannot lift them. Sealant is a backup here, not the main seal.
The roofer confirms that ridge vents, box vents and exhaust hoods are open and that intake at the soffits is not blocked. Balanced intake and exhaust keep the attic drier.
Damaged louvered vents are renewed before rain gets through the cracks.
Worn collars around vent pipes are renewed and lapped into the shingles.
Turbine heads that no longer spin are renewed so they stop leaking and squealing.
Damaged fan outlets on the roof are renewed with screens to keep birds out.
Loose ridge vent sections are reset with longer nails along with the cap shingles over them.
Every vent pipe on a roof has a boot, and the rubber part is where most of them fail. Sun and temperature swings dry out the rubber until it cracks around the pipe, and water then follows the pipe straight down into the attic. Lead boots resist sun, but animals often chew holes in them.
The best repair is a new boot lapped into the shingles. Repair collars that fit over the old boot are an option when replacement is not practical. Since boots of the same age crack around the same time, replacing all of them together makes sense.
Replacing a roof vent is common after hail or when an older vent wears out. Hail can shatter plastic vent hoods, rust eats through old metal vents and turbines eventually seize. Replacement uses the existing hole when it is the right size, with fresh laps into the roof.
Before replacing a vent, it is worth asking whether it is the right vent. Mixing exhaust types, such as ridge vents with box vents or power fans, can let one pull air in through the other instead of from the soffits. Ask whether the vent should be replaced with the same type or capped off.
Around Dumont, cracked pipe boots are one of the leading causes of roof leaks on otherwise healthy roofs. Across Dumont and nearby communities including Haworth, New Milford, Bergenfield and Cresskill, the mix of vents varies from house to house, and each type wears out in its own way, so it helps to tell the roofer what kind of vents you have.

Cold winters bring snow, ice and a long stretch of freezing nights. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, building ice dams that push water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Dumont is busiest after a hard winter and before the next one.
A roof problem fixed early rarely spreads to the decking, the insulation or the ceilings.
