Marana Roof Pros provides professional flat & low-slope roofing in Marana, AZ for residential and commercial properties across northwest Tucson and the lower Santa Cruz Valley. The flat roof on a Marana house is almost never a real flat roof. It is a small parapeted patio deck, a garage that ties into the main house, or a strip of low slope hidden behind a mansard, and everybody who touches the building treats it as an afterthought.
Those small areas cause a wildly disproportionate share of leaks. They are where two roof types meet, where a parapet wall and a deck move against one another, where the scupper was undersized on the drawing, and where a previous owner's handyman emptied a bucket of black mastic. The transition down from tile or shingle is the joint that fails. Black mastic in a bucket is a symptom of that history, never a repair of it.
We rebuild that transition instead of resurfacing across it. Membrane gets carried up the wall to a proper height and terminated into a saw-cut or under a metal bar rather than glued to stucco, and the tie-in is built so the sloped material laps over the low-slope material with a formed metal transition sitting between the two. Stucco is not a bonding surface and never has been.
Drainage gets the same attention. Twelve inches of rain a year still arrives in a couple of violent hours, and a scupper sized for a gentler climate backs water against a parapet never designed to hold any. We measure the opening, add overflow provision where none exists, and correct low spots in the substrate before anything gets installed over them. Overflow provision is cheap while the roof is open and expensive afterward.
For material we use single-ply membrane or a two-ply SBS system laid on rigid cover board, chosen by how the deck was built and how much foot traffic the area takes. Ponding areas get slope built into the assembly rather than another coating layer, because adding thickness over a low spot does not move water anywhere at all. Cover board also gives the fasteners something to hold that is not old insulation.
We will not sell you a coating as a substitute for a failed membrane on one of these decks. Wet substrate under a fresh coating stays wet, and all you have purchased is a year. On a sound membrane approaching the end of its warranty a maintenance coat is reasonable, and we will name which of them you have. That answer takes a moisture check, not a look.
Our licensed and insured team brings the right materials and equipment to every job — mechanically fastened hip and ridge with a flexible closure strip, two-piece counterflashing with a slip joint at the chase, roof plane deviation checked with a string line and story pole, hydrocompactive alluvial fill under old flood-irrigated cotton ground, 115 mph residential design wind speed from the town criteria sheet, model plan cohort defects repeating down a single subdivision street — and backs the work with a written workmanship warranty. We serve Marana and nearby communities including Tucson, Casas Adobes, Catalina Foothills, Oro Valley.

Materials, equipment and how we do flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with mechanically fastened hip and ridge with a flexible closure strip, two-piece counterflashing with a slip joint at the chase, roof plane deviation checked with a string line and story pole, hydrocompactive alluvial fill under old flood-irrigated cotton ground, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Marana job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in northwest Tucson and the lower Santa Cruz Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Marana Chooses Marana Roof Pros
- ✓We diagnose from inside the house before we get on the roof, because a frame that has shifted tells you which joint opened long before the roof does.
- ✓We ask what your neighbors have had repaired. Model plan subdivisions repeat one roof detail across a whole street, and cohort failures are found by comparison, not by guesswork.
- ✓We price corrections. If two hundred square feet of wall flashing is the problem, that is the quote you get, even when the roof is old enough to sell you a full replacement.
- ✓We refuse products we do not believe in here, including tile sealers and rejuvenating sprays, and we will tell you what they actually do to a joint that keeps moving.
