Water Down An Inside Wall
Streaks running down a brick wall inside, below the roofline, tend to trace back to the parapet above.
Open Coping Joints
Coping stones or metal caps with open joints let rain into the wall cavity behind the base flashing.

Downtown Angle
Parapet Roofs And Historic Review Downtown
Downtown storefronts often share walls and sit behind masonry parapets, so the roof edge is a wall with coping on top and scuppers cut through it. Water leaves through those openings, and most leaks start where the membrane turns up the parapet.
Mesa has eight locally designated historic districts, several close to downtown. Visible roof changes on a designated building go through the city’s Certificate of Appropriateness review, so we check with the Mesa Historic Preservation Office before choosing materials.
- Parapet base flashing and coping joints checked first
- Through-wall scuppers cleared and resealed
- Material staged from the alley where one exists
- Reroof permits through City of Mesa Development Services
Downtown Roof Conditions
Leak Signs In Older Downtown Buildings
Older masonry buildings show roof trouble in their own way. Each pair connects a sign inside with the parapet or roof detail behind it.
Stain Near The Front Wall
Ceiling stains near the street side often appear where the roof drains toward a scupper.
Clogged Through-Wall Scupper
Debris in a scupper cut through the parapet holds water against the membrane until it finds a gap.
Efflorescence On Brick
White mineral deposits on interior brick show water moving through the masonry from the roof edge.
Failed Base Flashing
Membrane turned up the parapet shrinks and pulls away from old brick, opening the corner where wall meets deck.
Leak In The Suite Next Door
Water showing up next door points to the joint where two roofs meet at a common wall.
Split Seam At A Party Wall
Two roofs tied together over a shared wall move differently, and the seam or flashing between them splits.
Cracked Ceiling Plaster
Plaster cracking below the top floor after summer often follows a roof surface worn thin by heat.
Worn Surfacing On Old Roofs
Granulated cap sheets and older coatings lose their surfacing under years of sun, exposing the membrane beneath.
Why It Pays
Roof Gains For Downtown Mesa Property Owners
A downtown reroof is mostly edge work. These gains come from getting the parapets, coping, and scuppers right while the roof is open.
A Tight Parapet Edge
New base flashing up the parapet, sealed coping joints, and reset scuppers close the openings where older downtown buildings take on water. Handling that work during a reroof means fewer wall leaks to chase one storm at a time afterward.
Review Handled Before Work
Checking historic status before choosing materials keeps a visible roof change on a designated building from stalling once the old roof is open.
Storefronts Stay Clear
Staging from the alley where one exists keeps sidewalks and entrances open while material moves up to the roof.
Water Off The Roof Faster
Cleared and resealed scuppers move monsoon rain off low roofs behind parapets before it stands against the walls.
Systems
Roof Systems We Install In Downtown Mesa
Two membrane systems fit the low roofs behind downtown parapets.
TPO Roofing
Welded TPO flashing turns up the parapet and wraps scupper openings as one piece, which fits storefront roofs with many wall details.
Best For
- Low roofs behind parapets
- Buildings with rooftop units
Look Elsewhere
- Visible slopes under historic review
- Heavily patched rubber roofs
EPDM Roofing
Older downtown buildings often already carry EPDM, and a sheet in fair shape can be repaired and coated instead of torn off between masonry walls.
Best For
- Existing rubber roofs in fair shape
- Roofs with odd penetrations
Look Elsewhere
- Wet insulation across the roof
- Two existing roof layers

How We Reroof Behind A Parapet
Five steps, adjusted for masonry walls, shared roofs, and historic review.
Step 1
Step 5Inspect Your Roof
Starting at the edges, we check coping joints, parapet base flashing, through-wall scuppers, and the seams where neighboring roofs meet. A moisture check shows whether water has reached the insulation.
Check Historic Status
Before materials are chosen, we confirm with the Mesa Historic Preservation Office whether the building is a designated resource and whether the visible roof change needs Certificate of Appropriateness review.
Repair Or Replace?
Dry insulation and an intact membrane field point to edge repairs and new flashing. Wet board across the roof, or two existing layers, means removal down to the deck.
Stage From The Alley
Material moves up from the alley side wherever one exists, so storefront doors stay open. Opened roof sections are dried in each evening, with tarps weighted against desert wind.
Flash The Edges And Walk It
Parapet flashing, coping, and scuppers go in last and get checked with water before we leave. Then you walk the roof with us and see each edge detail.

Downtown Questions
Commercial Roofing Questions For Downtown Mesa
Answers for owners of older storefronts and masonry buildings downtown.
Common Question
Do Historic Review Rules Apply To Roofs Near Downtown Mesa?
They can. Several of Mesa’s eight locally designated historic districts sit close to downtown, and the city also lists individual landmarks.
When a building is a locally designated resource, a roof change people can see from the street can need the city’s Certificate of Appropriateness review. We check with the Mesa Historic Preservation Office before choosing materials.
Who Issues Reroof Permits For Downtown Buildings?
Downtown sits inside the City of Mesa, so reroof permits go through City of Mesa Development Services, the same office that covers the city’s other districts. Permit triggers and fees change, so we confirm the requirements for the address before work starts.
Does It Matter That Downtown Has City Electric Service?
For incentive programs, yes. The City of Mesa runs its own electric utility for an area of about 5.5 square miles centered on downtown, while SRP serves most of the rest of Mesa. Any cool roof program depends on which utility serves the meter, so we confirm terms with that utility before ordering material.
How Do You Handle Roofs Shared Across A Party Wall?
We look at both sides of the joint. Two roofs tied together over a shared wall move differently, so the flashing between them needs room to flex. When a neighbor’s roof is part of the problem, we show both owners where the joint failed so the repair covers it.
What Happens To Coping On An Older Parapet?
Loose or cracked coping gets reset or replaced so its joints shed water away from the wall. On masonry caps the joints are resealed; on metal caps, new cleats and joint covers hold the pieces through wind. The base flashing below the coping is replaced at the same visit.
Why Do Scuppers Leak On Older Buildings?
Through-wall scuppers sit at the lowest point of the roof, so they hold debris and water longest. The metal liner rusts and the seal to the membrane dries out. We clear the opening, replace or reline the scupper, and flash it into the new membrane.
Can A Roof Be Replaced Without Using The Sidewalk?
Often, yes. Where an alley runs behind the building, material goes up from that side and debris comes down there too. On blocks without alley access, we plan a short, marked staging zone and work hours that keep storefront entrances clear.
