Rubber Roof Installation Denville, NJ
A Denville roofer who installs EPDM can put a new rubber roof on a flat or low slope section of almost any home, and explain each choice before the sheet is rolled out. Call (862) 421-0116 to reach a local roofer.
EPDM is the material most people mean when they say rubber roof. 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. 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. On most homes, fully adhered EPDM is the usual choice because it handles wind well and stays smooth.
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. 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 Denville, NJ can go hand in hand with rubber roof repair and flat roof installation.

How rubber roof installation works
Each layer is set up to give the membrane a smooth, solid base.
Prepare the deck
The deck is repaired and checked for slope, ideally a quarter inch per foot toward drains or gutters. On a replacement, old layers come off first.
Install insulation
Rigid insulation, often polyiso, is fastened with plates and screws, then a cover board goes on top. Slope can be built in at this stage.
Lay the sheet
The EPDM is unrolled, positioned and left to relax so wrinkles flatten before any adhesive goes on. Seams are planned so they run with the slope.
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. The process repeats for the second half. Any trapped air is worked out so the sheet lies flat and does not blister.
Seaming
Laps are primed and joined with seam tape, then rolled to remove air. Tape edges are finished with lap sealant.
Flashing
Perimeter edge metal, wall flashing and pipe boots complete the roof. Termination bar and counter flashing seal the wall edge. A final walk checks every seam with a probe before the job is closed out.

EPDM Roof Installation Denville, NJ
EPDM roof installation is straightforward in concept and demanding in the details. 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. 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 Denville installer also plans for movement. Flashing at walls and curbs is secured with termination bar so the sheet cannot pull loose as it ages, and corners get flexible uncured flashing. It is worth asking how the edges will be secured.

How the weather here affects roofs around Denville
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. 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. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Denville, NJ have the roof checked in the fall and again after the snow melts.

Rubber Roof Installation FAQ
What is the lifespan of a new EPDM roof?
EPDM can last 25 years or longer. Thickness, seam quality and maintenance all affect its life. Small repairs are easy to make.
Can a rubber roof go over an existing roof?
EPDM can sometimes go over an existing 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. If the old roof is wet, it must come off. The roofer tests the old roof for moisture before recommending a recover.
Should my rubber roof be black or white?
Color affects heat gain. Black holds heat and white reflects it. Ask about both options.
What is the difference between EPDM and TPO?
The two are different materials. Black EPDM is taped and stretchy, and white TPO is welded and reflective. A roofer can help you choose.
How thick should a rubber roof be?
The common choices are 45 mil and 60 mil. Thicker 60 mil is tougher and longer lasting. Even thicker sheets are available for demanding roofs.
