Flat Roof Replacement Maplewood, NJ
Replacing a flat roof in Maplewood starts with a moisture survey that decides whether the old roof must be torn off or can be recovered, with the material chosen to suit the building. Dial (973) 858-1830 to talk with a local roofer about replacing the roof.
Every flat roof eventually wears past what repairs can handle. Aging membranes lose flexibility, seams fail one after another and moisture works into the insulation. Saturated insulation loses its insulating value and keeps the deck damp.
Before anything else, the roofer decides whether to strip the roof or recover it. Recovering is allowed only over one existing layer with dry insulation and a sound deck. If two roofs already exist, or the scan finds wet insulation, a full tear-off is required.
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. Fresh edge metal, coping and drain bowls make it complete.
Many flat roof replacement calls in Maplewood also turn up a need for flat roof installation or flat roof repair.

How flat roof replacement works
A flat roof replacement is planned from the deck up.
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.
Choose the system
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
The old membrane, gravel and wet insulation are removed in sections, with each section dried in before the end of the day. Gravel-surfaced built-up roofs produce heavy debris.
Deck work
Rotted wood decking is replaced, and rusted metal deck is repaired, so the new roof has a solid base. Low areas are measured so insulation can correct them.
Insulation layer
Insulation boards, often polyiso, go down with tapered sections and crickets that move water toward drains and scuppers. This is what ends chronic ponding.
Install the membrane
The membrane goes on with new flashing, edge metal, coping and drain bowls. A final walk checks every seam and detail.
What is included
What the replacement includes
Tear-off
The existing roof is stripped to the deck so the new roof starts clean.
Moisture survey
The roof is scanned before any work begins so no wet insulation stays behind.
Edge metal
Drains, scuppers and edges are replaced for a clean, sealed edge.
New insulation
Insulation is upgraded with built-in slope for better drainage and comfort.

Low Slope Roof Replacement Maplewood, NJ
Low slope roofs have some pitch but not enough to shed water like a steep roof, and replacing them takes material suited to that slope. Many of these roofs were first covered with shingles or rolled roofing that does not suit the pitch, which is why they leak. The new roof should match the pitch, using a membrane or properly underlaid shingles.
The transition between low and steep sections is the critical detail. The transition is lapped so water flows over each layer. Ask the Maplewood roofer to explain how the low slope section ties into the rest of the roof.

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. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Maplewood is busiest after a hard winter and before the next one.

Flat Roof Replacement FAQ
Is it possible to recover a flat roof instead of tearing it off?
That is possible only when the existing roof meets a few conditions. There can be only one existing roof, the insulation must be dry and the deck must be sound, which a moisture survey confirms. When any of those fail, tear-off is the only option.
When is it time to replace a flat roof?
Pay attention to the whole roof rather than one stain. 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?
Lifespans range from about 15 to 30 years by material. Good drainage and regular maintenance stretch any flat roof’s life. A new roof with proper slope tends to last longer than the one it replaces.
Will a new flat roof fix standing water?
Replacement is the best time to solve ponding. The roofer can add tapered insulation, crickets and new drains so water leaves the roof. A new membrane alone will not stop ponding if the slope stays the same.
Which flat roofing material is best?
The right material depends on the building and how it is used. 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.
