Rubber Roof Installation Randolph, NJ
A roofer in Randolph 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, with as few seams as possible. Call (973) 858-1826 to reach a local roofer.
EPDM is the material most people mean when they say rubber roof. The membrane is thick, stretchy rubber that tolerates temperature swings and resists hail and sunlight well. Unlike TPO and PVC, its seams are taped rather than heat welded.
The first decision is how the membrane is held down. Fully adhered roofs bond the whole sheet to the cover board with adhesive, mechanically attached roofs use plates and fasteners along the seams and ballasted roofs hold a loose sheet down with river stone. Residential roofs are most often fully adhered.
Thickness and color are the next choices. Sixty mil EPDM costs a little more than 45 mil but resists punctures better and lasts longer. White EPDM suits sunny roofs, and black suits cooler climates. Where the rubber meets a shingled roof or the house wall, the tie-in detail matters as much as any of these choices.
Depending on what the roofer finds, rubber roof installation in Randolph, NJ can go hand in hand with rubber roof repair and flat roof installation.

Call nowThe process
What happens during a rubber roof installation
Each layer is set up to give the membrane a smooth, solid base.
Deck prep
The roofer checks the deck for rot, gaps and loose sheets and confirms the roof has enough slope to drain. On a replacement, old layers come off first.
Add the cover board
Rigid insulation, often polyiso, is fastened with plates and screws, then a cover board goes on top. Tapered boards add slope where needed.
Lay the sheet
The membrane is unrolled, aligned and allowed to settle before bonding. Seam layout follows the direction of drainage.
Adhering
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. The process repeats for the second half. Any trapped air is worked out so the sheet lies flat and does not blister.
Seal the seams
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
Perimeter edge metal, wall flashing and pipe boots complete the roof. Counter flashing covers the top of wall flashing. Before the crew leaves, seams are probed for any loose spots.

EPDM Roof Installation Randolph, NJ
Installing EPDM well comes down to preparation, seams and flashing. The membrane has to lie flat on a clean, dry cover board, the adhesive has to reach the right tack before the sheet is laid and every seam has to be primed and rolled with care. Dry, mild days give the best bond. Some installers use water-based adhesive for the field of the roof and solvent-based adhesive at walls and curbs, where the grip has to be strongest.
For a Randolph home, the installer thinks ahead to how the roof will behave over the years. Perimeter securement and proper flashing help prevent the shrinkage problems older rubber roofs show. It is worth asking how the edges will be secured.

What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder 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. Most homeowners in Randolph, NJ have the roof checked in the fall and again after the snow melts.

Common questions about rubber roof installation
Is a rubber roof the same as TPO?
The two are different materials. EPDM uses taped seams and stays flexible in cold, and TPO uses welded seams and reflects heat. Both are common on flat roofs.
How long does a new rubber roof last?
Rubber roofs often last decades. Good seams, drainage and occasional checks make the difference. Patching EPDM is straightforward.
What color EPDM is best?
Black and white each have their place. Black holds heat and white reflects it. Talk through the choice with a roofer.
Can a rubber roof go over an existing roof?
EPDM can sometimes go over an existing roof. The old roof must be a single dry layer, with a recover board over it. Otherwise, a tear-off is needed. The roofer tests the old roof for moisture before recommending a recover.
How thick should a rubber roof be?
The common choices are 45 mil and 60 mil. Thicker 60 mil is tougher and longer lasting. Heavy duty options exist too.
