Flat Roofing in Florence, AZ
We repair, recoat and replace flat and low-slope roofs on parapet and territorial-style homes. You get a written scope, a realistic start date, an arrival window on work days and a call from us if weather moves the plan.
What Flat Roofing Covers and When It Fits
A flat roof is never truly flat. It needs a slope of at least a quarter inch per foot to push water toward the scuppers or drains, and a membrane that stays watertight where it meets parapet walls, rooftop units and vent pipes. Most leaks start at those transitions, not in the open field of the roof.
In desert sun, a modified bitumen cap sheet loses its granules and the asphalt underneath dries out and cracks. Older built-up roofs blister as trapped moisture expands in the heat. If the membrane is still firmly attached and the deck is dry, a restoration coating can buy years. If it is saturated or split, replacement is the honest answer, and we will tell you which one you have.
We are an Arizona KB-2 licensed contractor, and flat roofs are a regular part of our work. If you are weighing a sprayed system instead, our Foam Roofing page explains how that option compares.
What the Work Includes
Membrane replacement
We tear off failed layers down to the deck and install a new modified bitumen or TPO system. Seams are heat-welded or torched, then probed so a weak lap does not slip past us.
Parapet and wall flashing
Base flashing runs up the parapet and is terminated under a counterflashing or coping. This is where stucco cracks let water behind the membrane, so we seal it as its own step.
Scupper and drain work
We reset scuppers, add lead or metal sleeves where they have rusted through, and correct low spots so water leaves the roof instead of sitting for days.
Rooftop unit curbs
Evaporative coolers and package units sit on curbs that need their own flashing. We coordinate disconnecting and lifting a unit when the membrane has to run underneath it.
Restoration coatings
For a sound roof, we clean, prime and apply an elastomeric coating that reflects heat and seals hairline cracks. We only recommend it when the membrane underneath can hold it.
Signs Your Flat Roof Needs Work
Water that sits after rain
Ponding that lasts more than two days after a monsoon storm means the slope or drainage has failed. Standing water speeds up membrane breakdown and adds weight to the deck.
Blisters and alligatoring
Raised bubbles or a cracked, scaly surface mean the roofing has dried out or moisture is trapped under it.
Bare, shiny cap sheet
When the granules are gone, the asphalt takes direct UV. Cracking usually follows within a few summers.
Stains near walls or coolers
Ceiling spots along an exterior wall or under a rooftop unit usually point to flashing, not the field of the roof.
Soft spots underfoot
A deck that gives when you step on it has likely absorbed water, which changes a repair into a replacement.
How a Flat Roof Job Runs
- 1
Your call and a site visit
On the phone we ask about the roof's age, the leaks and any rooftop units. We set a visit with an arrival window and walk the roof, taking photos of what we find.
- 2
Written scope and a real date
You get a line-item estimate that names the membrane, the flashing work and any deck repair we expect. We give you a start date we can actually meet and tell you how many work days to plan for.
- 3
Weather check before tear-off
We never open a roof with storms in the forecast. If the weather turns, we call you the day before with a new date instead of letting you find out when no crew arrives.
- 4
Tear-off and dry-in the same day
In summer we start early to work in the cooler hours. Whatever we remove gets covered or dried in before we leave, so your home is never left open overnight.
- 5
Water test, cleanup and walkthrough
A hose goes into every drain and scupper so we can watch the water leave the roof. Our crew rolls a magnetic sweeper over the driveway, walkways and planting beds to pick up stray fasteners and scraps. Then we review the finished roof with you, and your paperwork includes photos of the new seams and flashing.
What Moves the Price
Flat roof pricing depends far more on what is under the surface and around the edges than on square footage alone. Your written estimate breaks out each of these so nothing is buried in a single total.
- Layers to remove
- Many older roofs have two or three layers. Each one adds tear-off labor and disposal weight.
- Deck condition
- Wet or rotted sheathing has to be cut out and replaced. We show you photos before we add it to the job.
- Membrane choice
- Modified bitumen, TPO and coatings differ in material and labor, and each suits a different roof condition.
- Drainage corrections
- Fixing chronic ponding may mean tapered insulation or new scuppers, which adds material but stops the cause of the failure.
- Parapets and rooftop units
- Linear feet of parapet flashing and the number of curbs, coolers and penetrations all add detail work.

How long does a flat roof replacement take?
Most single-family flat roofs take one to three work days once we start. Multiple layers, deck repair or a unit that has to be lifted can add a day. We tell you the expected length up front and update you each evening if it changes.
Can my roof be coated instead of replaced?
Sometimes. A coating works when the existing membrane is still adhered to the layers below, dry and mostly intact. If we find saturated insulation or a soft deck, coating over it traps the water, so we will recommend replacement instead.
Which membrane do you recommend?
It depends on the roof. Modified bitumen handles foot traffic around coolers well and repairs easily. TPO reflects more heat and has welded seams. We explain the tradeoffs for your roof in the estimate.
What happens if weather pushes my start date?
We watch the forecast for the days around your start and call you as soon as we decide to move it. You get a new date during that same call, not a vague promise to get back to you.
Is the work covered after you finish?
Yes. Our flat roof work carries a 10-year labor warranty. Material coverage comes from the membrane manufacturer, and we explain what applies to the product we install.
