Two-flat owners type rubber roof, and almost nobody publishes that phrase
The words your customers use for a low-slope roof are not the words on your services page.
Much of the housing stock here has a flat or low-slope roof. Two-flats, three-flats, greystones, courtyard buildings, and the back half of plenty of bungalows. The owners do not call it low-slope. They call it a rubber roof, a tar roof, a torch-down roof, or just the flat.
A site that says only TPO, EPDM and modified bitumen misses every one of those searches. Publish both vocabularies. Use the trade term as the heading, put the homeowner's term in the first line, and answer the question underneath.
Each membrane deserves its own page, including what it costs to get wrong: a recover laid over wet insulation, a failed seam detail at the parapet, drains that pond after a thaw. Write it the way you would explain it to a neighbor standing in the alley.
Those pages look small next to a national roofing blog. They also match a query somebody types once, right before they call three companies.
