Flat Roof Replacement Randolph, NJ
A roofer in Randolph can replace a worn flat roof by removing the old membrane and wet insulation, fixing the deck and installing a new system with proper slope, flashing and edge metal, and the chance to fix the slope and insulation along the way. Call (973) 858-1826 to reach a local roofer.
Every flat roof eventually wears past what repairs can handle. Over time, seams open, the membrane cracks and blisters and wet insulation spreads under the surface. Saturated insulation loses its insulating value and keeps the deck damp.
The first decision in a flat roof replacement is tear-off or recover. A recover lays new insulation or a cover board and a new membrane over the existing roof, and codes generally allow it only when there is a single existing roof and the insulation is dry. Wet insulation, a second existing layer or a damaged deck means everything comes off.
Replacement is also the best chance to fix what the old roof did wrong. Low spots that held water can be built up with tapered insulation, and drains can be added or moved. All metal edges and drains are replaced with the new roof.
If the problem goes deeper than it first looked, a Randolph roofer may also recommend flat roof installation or flat roof repair.

What happens during a flat roof replacement
Getting the base right is what makes a new flat roof last.
Moisture survey
The roofer checks how many layers exist and uses core cuts, moisture meters or an infrared scan to map wet insulation. The scan settles the tear-off question.
Material choice
Material options include heat-welded TPO and PVC, EPDM rubber and modified bitumen. Attachment method and insulation thickness are set at the same time.
Tear off
Old layers come off in manageable sections that are sealed before evening. Gravel-surfaced built-up roofs produce heavy debris.
Fix the structure
Rotted wood decking is replaced, and rusted metal deck is repaired, so the new roof has a solid base. Problem areas are marked for added slope.
Build in slope
New insulation is laid with built-in slope, then capped with a cover board. This is what ends chronic ponding.
Install the membrane
Seams are welded or taped, flashing goes up walls and curbs and new edge metal and drains complete the roof. Seams are probed and checked before the job is closed out.

Low Slope Roof Replacement Randolph, NJ
Low slope roof replacement applies to roofs with a little pitch, roughly 2 in 12 to 4 in 12, such as porch roofs, sunrooms and older additions. Many of these roofs were first covered with shingles or rolled roofing that does not suit the pitch, which is why they leak. Replacement is a chance to switch to a membrane or to shingles with the doubled underlayment that low pitches require.
Where the low slope roof meets a steeper roof or the house wall is where most leaks start. The roofer runs the membrane up under the shingles of the steeper roof and flashes the wall with step or counter flashing. For a Randolph home, getting the tie-in right prevents most future leaks.

Roofs in this climate
Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Randolph, NJ have the roof checked in the fall and again after the snow melts.

Common questions about flat roof replacement
Can a new flat roof go over the old one?
That is possible only when the existing roof meets a few conditions. Codes generally allow one recover over a single existing roof with dry insulation. When any of those fail, tear-off is the only option.
When is it time to replace a flat roof?
Look at how widespread the problems are. Widespread seam failure, surface cracking and wet insulation point to the end of the roof’s life. Testing shows how much of the roof is still dry.
How long does a flat roof last?
The answer depends on the membrane, installation and maintenance. EPDM, PVC and well installed modified bitumen are often at the longer end, while poorly drained roofs wear out faster. A new roof with proper slope tends to last longer than the one it replaces.
Can ponding be fixed when the flat roof is replaced?
Ponding can be corrected during replacement. Tapered insulation adds slope toward drains, crickets divert water around curbs and walls and drains can be added or lowered. Without added slope, water will still sit in the same spots.
What is the best material to replace a flat roof with?
Every membrane suits some roofs better than others. TPO and PVC are white, reflective and heat welded, EPDM is flexible black rubber with few seams, and modified bitumen is a tough multi-ply asphalt roof. A roofer can match the material to your roof.
