Rubber Roof Installation Mountainside, NJ
A roofer in Mountainside can install a rubber roof by laying EPDM membrane in wide sheets over insulation and a cover board, bonding or fastening it down and sealing every seam with primer and tape, and explain each choice before the sheet is rolled out. Call (908) 728-6030 to reach a local roofer.
A true rubber roof is EPDM, a synthetic rubber membrane used on flat and low slope roofs for decades. EPDM is sold in wide rolls, typically 45 or 60 mil thick, and it stretches and recovers as the roof moves through hot and cold seasons. That flexibility is why it suits so many homes.
Attachment method shapes the rest of the installation. The sheet can be glued to the substrate, fastened with plates at the seams or laid loose under a layer of stone. For homes, adhered EPDM is the most common choice.
Then comes thickness and color. Thicker 60 mil membrane stands up better to foot traffic and hail. White EPDM suits sunny roofs, and black suits cooler climates. The installer also plans how the membrane laps under shingles above it and up the wall beside it, where leaks tend to start.
If the problem goes deeper than it first looked, a Mountainside roofer may also recommend rubber roof repair or flat roof installation.

What happens during a rubber roof installation
A rubber roof is built in layers, with the seams and flashing as the critical details.
Deck prep
Damaged decking is replaced and drainage is confirmed before any insulation goes down. A tear-off comes first on existing roofs.
Insulation
Rigid insulation, often polyiso, is fastened with plates and screws, then a cover board goes on top. Low spots can be corrected with tapered insulation.
Lay the sheet
Wide sheets are laid out to cover the roof with as few seams as possible, then allowed to relax. Seam layout follows the direction of drainage.
Bond the membrane
Bonding adhesive is rolled onto both the cover board and the underside of the rubber, then the sheet is folded back down and broomed smooth. Then the other half is done the same way. Brooming from the middle outward pushes trapped air to the edges.
Seaming
Seam areas are cleaned and primed, then seam tape is applied and rolled firmly with a seam roller. Exposed edges get lap sealant.
Flash the details
Flashing goes up walls and around curbs, with boots at pipes and new edge metal at the perimeter. Counter flashing covers the top of wall flashing. The last step is probing each seam and patch for gaps.

EPDM Roof Installation Mountainside, NJ
Installing EPDM well comes down to preparation, seams and flashing. Rushing the adhesive, skipping primer or leaving wrinkles under the sheet are the common mistakes. Weather matters too, since adhesives and primers need dry conditions. Different adhesives may be used in the field and at the flashings, each matched to the job it does.
A good Mountainside installer also plans for movement. Perimeter securement and proper flashing help prevent the shrinkage problems older rubber roofs show. It is worth asking how the edges will be secured.

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, 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 Mountainside, NJ have the roof checked in the fall and again after the snow melts.

Rubber Roof Installation FAQ
Is a rubber roof the same as TPO?
EPDM is synthetic rubber, while TPO is a thermoplastic membrane. EPDM uses taped seams and stays flexible in cold, and TPO uses welded seams and reflects heat. Both are common on flat roofs.
What color EPDM is best?
The choice depends on the climate and the space below. Black holds heat and white reflects it. Talk through the choice with a roofer.
How thick should a rubber roof be?
Most residential EPDM is 45 or 60 mil. Thicker 60 mil is tougher and longer lasting. Even thicker sheets are available for demanding roofs.
What is the lifespan of a new EPDM roof?
Rubber roofs often last decades. Thickness, seam quality and maintenance all affect its life. Small repairs are easy to make.
Can a rubber roof go over an existing roof?
Recovering depends on the condition of the old roof. There should be only one existing layer, the insulation must be dry and a cover board or recover board goes between the old roof and the rubber. Otherwise, a tear-off is needed. Core samples or a moisture scan show whether the old roof is dry enough.
