Cost breakdown
This estimate converts a 1,500 sq ft footprint into roof area using a standard pitch multiplier, adds a moderate waste factor, then applies the installed cost range for PVC Membrane. It is a planning range, not a contractor bid, but it gives homeowners a fast baseline before comparing local quotes.
PVC Membrane installed roof system
Low, average, and high allowance
$11,975–$25,946
Tear-off, disposal, and site cleanup
Low, average, and high allowance
$1,650–$4,125
Pipe/chimney/skylight flashing (2×)
Low, average, and high allowance
$300–$900
What 1,500 Sq Ft Means on a Roof
A 1,500 sq ft footprint is about 15 roofing squares. That is the unit roofers actually quote in, order in, and pay disposal by.
A 1,500 sq ft home is typically a rectangular ranch or cape with a single front-to-back gable and maybe one porch tie-in. Straight runs dominate, so a crew racks through it fast once the old layer is off.
Waste factor
7-10%. Long open runs with a single ridge mean few odd cuts, and bundles go down nearly in order.
Tear-off and dumpster
One layer assumed. 15 squares of debris fills a 10-yard box close to the weight line, so many crews bring a 15-yarder to stay safe on the scale ticket. Hauling is normally quoted inside the tear-off price.
Crew and days (membrane)
3 person crew, 1-2 days
Schedule reality
Permit takes a few days to two weeks in stricter towns. Shingle installs finish in a day. Inspection follows within the week.
Planning checklist at this size
- Plan on new drip edge and gutter apron rather than reusing the old. Eaves on ranches this age are the first thing to go.
- Have the eave insulation and baffles checked. They crush easily on long rafter runs and show up later as ice dams.
- One layer off and one layer on means the job can run start to finish without a second dumpster trip.
What changes the price?
Pitch and access
Steeper roofs require more safety setup, more labor time, and often more waste.
Tear-off layers
Old shingles, decking surprises, and disposal fees can move the final quote.
Valleys and penetrations
Chimneys, skylights, pipe boots, vents, and valleys add flashing detail and labor.
Material grade
PVC Membrane ranges widely by manufacturer, warranty, color, thickness, fasteners, and trim package.
