Modified Bitumen Roofing North Arlington, NJ
Modified bitumen roofing in North Arlington is a multi-ply asphalt roof, usually a base sheet and a granulated cap sheet, used on flat and low-slope roofs, after checking the deck, the drainage and what is left of the old roof. Call (551) 348-7205 to reach a local roofer.
Modified bitumen is asphalt with rubber or plastic polymers mixed in, made into reinforced rolls that go down in two or more layers. Sheets come in SBS, a rubber-modified type that handles cold well, and APP, a plastic-modified type made for torching. Multiple plies make a tough roof that tolerates foot traffic better than many single-ply sheets.
The application method is one of the first decisions on a modified bitumen job. Torch-down uses an open flame to melt the back of the sheet onto the layer below, which makes strong laps but calls for strict fire safety near wood and insulation. Self-adhered peel-and-stick sheets and cold-applied adhesives skip the torch, which makes them common on houses.
Mod bit fails in predictable ways, which helps when you call. Note any blisters or bubbles, cracking in the cap sheet, bare spots where granules have washed off and laps that are lifting at the edges. Also mention any past coatings or cement patches, which the roofer will need to deal with.
Depending on what the roofer finds, modified bitumen roofing in North Arlington, NJ can go hand in hand with flat roof replacement and flat roof repair.

Call nowThe process
The modified bitumen process
Each layer of a mod bit roof has its own job.
Inspect the roof
The roofer checks the deck, counts existing layers and looks for wet insulation, often with a core cut. That decides between a tear-off and laying new plies over a sound, dry existing roof.
Prep the base
Old roofing is removed where needed, rotted decking is replaced and the surface is swept clean. Insulation or a cover board is added, with tapered sections where water needs help reaching the drains.
Lay the base sheet
A smooth base sheet goes down first, fastened or adhered depending on the deck. Laps are offset so seams in the cap sheet do not land on seams below.
Lay the top ply
A cap sheet with mineral granules is applied over the base sheet. On torched laps, a steady bleed-out of asphalt at the edge shows a good seal.
Detail the edges
Walls, curbs and penetrations get reinforced flashing plies that run up and are capped with metal. Drains get new flashing, and the roof edge gets new metal.
Final check
Once the roof is done, the crew checks every lap, cleans up and keeps a fire watch if torches were used. The last step is a full walk to confirm laps and flashings are sealed.
What is included
Parts of a modified bitumen roof
Base flashing
Flashing that runs up the wall and under metal so wall joints stay dry.
Granulated cap
A granulated cap sheet in white or a dark color to shield the asphalt from sun.
Tapered insulation
New insulation where the roof is torn off built to current code levels.
Base sheet
The first ply of polymer-modified asphalt over a clean, sound deck.

Torch Down Roof Repair North Arlington, NJ
Repairing a torch-down roof usually means cutting out the bad section and fusing new modified bitumen over it. A blister is cut in an X or cut out, the area is dried and sealed, and a new piece of cap sheet goes over it. Granules are pressed into any exposed asphalt so the patch is protected from sun.
In North Arlington, many torch-down repairs sit close to wood framing, so fire safety is part of every job. Where a flame could reach wood or insulation, a self-adhered patch is the safer choice. After torching, a watch period for smoldering material is standard practice.

Built Up Roofing North Arlington, NJ
A built up roof is made of several plies of felt mopped together with hot asphalt or coal tar pitch, then flood-coated and covered with gravel. When the gravel thins out, the asphalt below dries, cracks and blisters. These roofs can last a long time, but blisters, splits and failed flashings show up as they age.
Most built up roof repairs in North Arlington start by clearing the gravel, then patching with new plies and setting gravel back in place. Because these roofs are heavy, recovering over one can strain the structure, and many owners choose a tear-off when the time comes. Common replacements include modified bitumen and single-ply membranes.

Roofs in this climate
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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. That is why roof repair in North Arlington is busiest after a hard winter and before the next one.

Common questions about modified bitumen roofing
Should I coat my modified bitumen roof?
Coating an aging cap sheet is a common way to add years to a mod bit roof. Before coating, the roofer repairs blisters and laps and may use a bleed-blocking primer. White coatings reflect sun, which helps the asphalt last.
What is the lifespan of a torch-down roof?
A two-ply modified bitumen roof commonly lasts around 15 to 25 years. Good drainage, intact granules and sound flashings push it toward the long end. Coating an aging but sound roof can add years.
How does mod bit compare to tar and gravel?
Both use asphalt, but the plies and surfacing differ. Built up roofing uses many plies of felt mopped with hot asphalt or coal tar and is topped with gravel, while modified bitumen uses fewer, thicker polymer-modified sheets with a granulated cap. Mod bit is often preferred today for its flexibility and lower weight.
Is torch-down roofing safe?
The open flame is the main concern with torch-down roofing. Good crews fasten the base sheet on wood decks, keep the flame away from edges and gaps and stay on fire watch afterward. Self-adhered sheets give the same kind of roof without a torch.
Do I need a tear-off for a new mod bit roof?
The core cut tells the roofer. If there is a single, dry, sound roof, a recovery board and new mod bit may go over it. If there are already two roofs, blistering throughout or wet insulation, a tear-off is the right move.
