Protecht Exteriors handles commercial roof repair on all major roofing systems in Ypsilanti — EPDM, TPO, modified bitumen, and built-up roofing (BUR). Ypsilanti's commercial repair market spans the historic downtown brick buildings with 40-to-70-year-old BUR systems, the Michigan Avenue strip commercial with modified bitumen and early EPDM from the 1980s and 1990s, and the Eastern Michigan University campus-adjacent institutional buildings requiring specialized repair approaches. Masonry parapet buildings in the historic district generate chimney counter-flashing and parapet wall flashing repair calls that require specific expertise in masonry-compatible flashing systems. The commercial repair conversation starts the same way every time: a physical assessment that determines whether the failure is localized and repairable, or whether the findings indicate underlying conditions that make repair the wrong investment. Protecht delivers a written scope with the honest answer — repair or replacement — before any work commitment is made. Our office is 40 minutes northwest via I-75 and US-23.
Commercial Roof Repair Types — What Protecht Addresses on Ypsilanti Commercial Buildings
Every Repair Starts With a Physical Assessment — The Written Scope Is Issued Before Any Work Begins
EPDM Seam Repair & Adhesive Resealing
EPDM seam adhesive failure is the most common commercial roof repair call on Ypsilanti's aging commercial inventory. The bonding adhesive that holds EPDM seams degrades from UV exposure at the exposed seam edge — the rubber membrane itself may be fully functional while the seam adhesive has lost its bond. Protecht cleans and prepares the seam surface, applies seam tape or fresh bonding adhesive, and seals the seam edge with EPDM lap sealant. Perimeter seams at parapet walls and drain sumps are the most common failure locations. When seam failures are localized (1 to 3 zones), targeted repair delivers meaningful life extension. When seam failures are widespread across the full membrane, replacement is the honest conversation.
⚠ EPDM seam repair requires temperature-appropriate adhesive cure conditions — cold Michigan temperatures affect adhesive set time. Protecht schedules and applies EPDM seam repairs within manufacturer temperature guidelines.
TPO Membrane Repair & Seam Welding
TPO membrane failures present as punctures, tears, or seam delamination — conditions that are repairable when localized. Protecht repairs TPO punctures and tears with factory-welded patches using hot-air welding equipment, producing a repair that is structurally as strong as the surrounding membrane when correctly executed. TPO seam delamination — seams that have separated from the substrate or from each other — is rewelded with hot-air equipment where the membrane condition allows. Field-applied TPO patches without heat welding are a temporary measure, not a permanent repair. Every Protecht TPO repair uses the same hot-air welding equipment and technique as a new installation.
⚠ TPO seam welding requires ambient temperatures above 40°F. In Michigan's cold shoulder seasons, early-morning temperature checks determine whether welding conditions are met before the crew begins.
Modified Bitumen Repair & Patch
Modified bitumen repairs address cap sheet cracking, blister formation, and localized membrane failure. Protecht removes the failed area back to sound membrane, installs SBS modified bitumen base sheet and granular cap sheet patch by torch application or cold adhesive, and feathers the patch edges to the surrounding membrane. Blistered areas are cut open, dried, and fully patched rather than surface-sealed — a blister that is resealed without addressing the moisture or air pocket beneath it will fail again at the same location. Modified bitumen's granular surface makes hail damage documentation straightforward — Protecht photographs cap sheet granule displacement patterns before repair for insurance documentation when storm damage is involved.
⚠ Torch application on occupied buildings requires fire watch protocol. Protecht uses certified torch applicators and maintains all required fire safety procedures on every occupied building repair.
Flashing Replacement — HVAC Curbs, Parapets & Penetrations
Failed flashing is the single most common cause of commercial roof leaks on Ypsilanti's commercial building inventory. Every penetration through a commercial roof — HVAC curb, plumbing stack, electrical conduit, skylight, exhaust fan — is a potential failure point where membrane meets vertical surface and thermal movement tests the flashing joint repeatedly through Michigan's seasonal cycle. Protecht replaces failed HVAC curb counter-flashing, parapet wall cap flashings, pipe boot collars, and all penetration flashings to NRCA specification. Flashing repairs are not caulk-over operations — failed metal flashing is replaced, not covered with sealant that will fail again at the next freeze-thaw cycle. Reglet counter-flashings at masonry parapets are re-anchored and resealed to masonry. All new flashing work is installed to current NRCA and manufacturer detail standards.
The most expensive commercial roof repair is the one that was deferred. A $600 HVAC curb flashing failure left unaddressed produces a $4,000 wet insulation replacement scope 18 months later. Protecht's assessment photographs all failing flashings — not just the ones that are actively leaking — so property owners can address the full scope before secondary damage accumulates.
Ponding Correction, Drain Repair & Tapered Insulation
Ponding water on a Ypsilanti commercial roof — water that stands for more than 48 hours after precipitation — is the single greatest accelerant of membrane aging and the most common reason flat commercial roofs fail before their expected service life. Ponding occurs when drains are blocked, when drain collectors have settled below the surrounding deck, or when the original roof slope is inadequate. Protecht addresses ponding through three approaches depending on cause: drain cleaning and collar replacement when the drain itself is failed or blocked; sump installation when the drain collector has settled and the existing drain can be relocated; and tapered polyiso insulation crickets when structural slope is insufficient and must be built above the deck. Ponding correction is one of the highest-return investments on any Ypsilanti commercial building — eliminating standing water extends the membrane's effective life more than any other maintenance action.
Michigan winters amplify ponding damage: water trapped on a flat roof through a freeze cycle creates ice that can stress membrane seams, displace ballast, and block drain sumps. Any ponding zone identified during a summer or fall inspection should be corrected before the first hard freeze.
How Protecht Diagnoses Commercial Roof Failures in Ypsilanti
The Leak Origin and the Leak Appearance Are Rarely in the Same Place on a Flat Commercial Roof
Why the Leak Location Is Misleading
Water that enters a flat commercial roof through a failed flashing or seam travels horizontally along the insulation layer or the deck surface before it finds a path down through the ceiling. The interior ceiling stain — the visible symptom the building manager calls about — can be 10 to 30 feet from the actual entry point. Chasing the stain to the area directly above it and applying caulk or a patch is the most common commercial roof repair mistake: it addresses the appearance of the problem rather than its source. Protecht's physical assessment starts at the roof surface and works methodically through all potential entry points — flashings, seams, penetrations, and drain sumps — to identify the actual failure location before any repair is specified.
The Repair vs. Replacement Determination
Not every commercial roof failure warrants repair. Protecht's assessment produces one of three findings: the failure is localized, the membrane and insulation are in sound condition, and targeted repair delivers meaningful life extension — repair is the right answer; the failure is symptomatic of widespread membrane deterioration or wet insulation — replacement is the honest answer; or the failure is repairable but replacement should be planned within 2 to 5 years — repair now, plan replacement. The written scope document states which outcome applies and why. Protecht does not recommend repair on a roof that needs to be replaced, and does not recommend replacement on a roof where targeted repair delivers real value.
Core Cuts — Confirming Insulation Condition
When a commercial repair assessment finds a leaking zone, the question beneath the membrane matters as much as what is visible above it: is the insulation beneath the failure wet and compromised, or dry and sound? Wet insulation discovered during a repair scope changes the scope dramatically — wet insulation must be removed and replaced, not sealed over. Protecht cuts cores at the failure zone during assessment to confirm insulation moisture content before specifying repair scope. A repair over wet insulation traps moisture in the assembly, accelerates steel deck corrosion, and eliminates the insulation's R-value in the affected zone — producing a larger problem than the original failure.
Emergency Response and Temporary Protection
When a Ypsilanti commercial building is actively leaking — during a rain event, after a storm, or from a sudden membrane failure — temporary protection stops the water infiltration and Category 3 water damage accumulation before the permanent repair scope can be assessed and executed. Protecht provides emergency tarping on commercial buildings when active infiltration is occurring and the repair cannot be completed immediately. Emergency tarps are installed to protect the interior and halt moisture damage, followed by a full assessment and written repair scope when conditions allow. Emergency response is available same day for active commercial leaks in Ypsilanti and the surrounding Washtenaw County service area.
When Repair Is the Right Answer — and When It Isn't
The Honest Assessment Produces One of Three Findings — Protecht States Which One Applies and Why
Ypsilanti's commercial repair market spans the historic downtown brick buildings with 40-to-70-year-old BUR systems, the Michigan Avenue strip commercial with modified bitumen and early EPDM from the 1980s and 1990s, and the Eastern Michigan University campus-adjacent institutional buildings requiring specialized repair approaches. Masonry parapet buildings in the historic district generate chimney counter-flashing and parapet wall flashing repair calls that require specific expertise in masonry-compatible flashing systems. The repair-versus-replacement decision on a Ypsilanti commercial building is not a gut call or a sales pitch — it is a finding that comes from the physical assessment. Protecht's written scope document states the finding, the evidence behind it, and the recommended path forward. The property owner receives this document before any commitment is made.
The most common scenario where repair is genuinely the right answer: a localized seam or flashing failure on a roof with 8 to 15 years of remaining membrane life, dry insulation confirmed by core cut, and sound structural deck. In this scenario, a targeted repair costing $500 to $3,500 buys a decade of additional service life that premature replacement would have eliminated. The most common scenario where replacement is the honest answer: widespread membrane failure, wet insulation in multiple zones, and a membrane at or past its expected service life. A repair in this scenario is money spent on a roof that needs to come off within 18 to 36 months — a deferred cost rather than a solution. Protecht will not recommend repair in this scenario. The written scope will say replacement, with the reasons documented.
The cost ranges for commercial repair in Ypsilanti: $500 to $7,500 depending on scope — historic Ypsilanti commercial buildings with masonry parapet complexity may run toward the higher end of the single-repair range; standard strip commercial repairs run $500 to $2,500. For comparison, commercial replacement on the same buildings runs considerably more — which is precisely why targeted repair on the right roof at the right time is worth the assessment investment. The assessment is free. The written scope is the property owner's before any commitment.
When Repair Is Right vs. When Replacement Is Right
Common Commercial Repair Findings in Ypsilanti
25-Plus Years of Commercial Roofing Experience in Washtenaw County
Ypsilanti's commercial repair market spans the historic downtown brick buildings with 40-to-70-year-old BUR systems, the Michigan Avenue strip commercial with modified bitumen and early EPDM from the 1980s and 1990s, and the Eastern Michigan University campus-adjacent institutional buildings requiring specialized repair approaches. Masonry parapet buildings in the historic district generate chimney counter-flashing and parapet wall flashing repair calls that require specific expertise in masonry-compatible flashing systems. The repair profile for Ypsilanti's commercial inventory reflects these building ages and system types: BUR alligatoring and felt-layer separation on historic downtown commercial, masonry parapet counter-flashing failure on Depot Town brick commercial, EPDM seam adhesive failure on Michigan Avenue strip retail, modified bitumen cap sheet cracking on 1980s–1990s commercial, and drain collar replacement throughout the commercial inventory.
The category of commercial repair that most consistently produces hidden scope is failed flashing. A building manager sees a ceiling stain and assumes a membrane failure — but the actual entry point is an HVAC curb counter-flashing that has separated from the curb base after 20 Michigan freeze-thaw cycles, or a parapet wall cap that has lost its sealant at the termination bar and is channeling wind-driven rain directly into the wall assembly. Protecht's assessment protocol specifically checks all flashings and penetrations — not just the area above the interior stain — because the leak origin and the leak appearance are rarely co-located on a flat commercial roof.
The second most underdiagnosed commercial repair category in Ypsilanti is ponding. Building managers often observe standing water on their commercial roof without recognizing it as an active damage mechanism. Water ponding for more than 48 hours after rain is accelerating the membrane's aging at every standing water zone — UV degradation occurs faster at the waterline than on the dry membrane surface, seam adhesives are softened by sustained moisture contact, and the thermal mass of standing water amplifies freeze-thaw stress at the waterline. Ponding correction — drain cleaning, drain collar replacement, or tapered insulation crickets — is one of the highest-return repair investments available on a Ypsilanti commercial roof.
Most Common Commercial Repair Calls in Ypsilanti
These are the repair types that appear most consistently on Protecht's assessment reports for Ypsilanti commercial buildings. Every repair begins with physical diagnosis — not a phone quote or a visual from the parking lot.
- EPDM seam adhesive failureUV degradation of bonding adhesive at exposed seam edges — the most common single repair call on Ypsilanti's aging EPDM inventory. Localized seam failures on otherwise sound membranes are the best-case commercial repair scenario: targeted resealing delivers years of additional service life at modest cost.
- HVAC curb counter-flashing failureEvery HVAC curb on a Ypsilanti commercial roof is a potential leak source. Counter-flashing metal corrodes; sealant at the base fails after repeated freeze-thaw cycles; the curb base separates from the membrane. Assessment identifies which curbs are actively leaking and which are in the pre-failure warning stage.
- Pipe boot and penetration seal failureEPDM and TPGO pipe boot collars crack from UV exposure and temperature cycling. Sealant at conduit and equipment penetrations fails. These are localized, repairable failures when caught early — they become insulation replacement scope when deferred through multiple Michigan winters.
- Drain collar deterioration and pondingDrain collars fail; drain sump collectors settle; debris blocks drain strainers. Ponding water accumulates. Protecht addresses the drain failure directly rather than just clearing the blockage — a drain collar that has failed will fail again at the next rain event if it is not replaced.
- Parapet wall flashing failureWind-driven rain at parapet walls — especially on Ypsilanti's west and south-facing building exposures — enters through failed termination bar sealant, separated cap flashings, and deteriorated coping joints. These failures are invisible from ground level and are found during the roof-surface assessment.
- BUR / modified bitumen alligatoring and blisterAlligatored BUR surface and blistered modified bitumen cap sheet indicate accelerated oxidation from deferred maintenance. Localized areas are patchable; widespread alligatoring across the full roof indicates replacement is the honest answer.
Protecht Commercial Roof Maintenance Program — Fewer Repairs, Lower Cost, 25% Off All Services
1 to 4 Visits Per Year · Drains · Seams · Penetrations · Licensed HVAC Contractor · Program Members Save 25% on All Repairs
Most commercial roof failures don't happen suddenly — they develop over months or years from small issues that become expensive problems when they go undetected. A blocked drain that sits through a Michigan winter. An HVAC curb flashing that's starting to separate. A pipe boot collar with a hairline crack. None of these announce themselves on the ceiling until the damage is already done. Protecht's Commercial Roof Maintenance Program puts a trained eye on your roof on a scheduled basis — catching the $400 problem before it becomes the $4,000 one.
Program members choose from 1 to 4 scheduled visits per year depending on building age, roof system type, and roof complexity. Each visit covers the full scope: drainage system inspection and cleaning, seam and membrane condition assessment across all roof planes, all penetration flashings and pipe boot collars checked, parapet wall and edge metal conditions documented, and a written visit report with photos delivered to the property owner or manager after each inspection. When maintenance items are found, they're documented and priced before any work is performed — no surprise invoices.
Protecht's maintenance program also includes access to a licensed HVAC contractor who inspects your rooftop HVAC units as part of the scheduled visit — checking refrigerant levels, electrical connections, coil condition, and curb integrity. The mechanical systems sitting on your roof are both a major building asset and a primary source of roofing failures when their curbs and flashings are neglected. Having both the roofing and HVAC condition assessed in a single scheduled visit closes the gap that leaves most commercial buildings with undetected failures at the roofing-mechanical interface.

Ypsilanti, MI Commercial Roof Repair FAQs
How do I know if my Ypsilanti commercial roof needs repair or replacement?
The determination depends on four variables: membrane age and overall condition; whether failure is localized or widespread; insulation condition confirmed by core cut (wet insulation typically triggers replacement); and structural deck condition. A localized EPDM seam failure on a 15-year-old roof with dry insulation is a repair. Widespread seam failures on a 28-year-old EPDM with wet insulation is a replacement. Protecht's written assessment states which finding applies and why — before any commitment is made.
What are the most common commercial roof repairs in Ypsilanti?
BUR alligatoring and felt-layer separation on historic downtown commercial, masonry parapet counter-flashing failure on Depot Town brick commercial, EPDM seam adhesive failure on Michigan Avenue strip retail, modified bitumen cap sheet cracking on 1980s–1990s commercial, and drain collar replacement throughout the commercial inventory. Every repair begins with a physical assessment to determine whether the failure is localized or indicative of broader membrane and insulation issues that would make repair the wrong investment.
Why is the leak location I can see inside often not where the roof is actually failing?
Water entering a flat commercial roof travels horizontally along the insulation layer or the deck surface before it finds a path down through the ceiling — sometimes 10 to 30 feet from the actual entry point. Patching the area above an interior stain is the most common commercial repair mistake. Protecht's assessment works through all potential entry points on the roof surface — flashings, seams, penetrations, and drain sumps — to identify the actual failure before any repair is specified.
How much does commercial roof repair cost in Ypsilanti?
$500 to $7,500 depending on scope — historic Ypsilanti commercial buildings with masonry parapet complexity may run toward the higher end of the single-repair range; standard strip commercial repairs run $500 to $2,500. The specific number depends on the failure type, membrane system, extent of damage, and whether wet insulation or deck damage is found during assessment. Protecht provides a written estimate after the physical assessment — not a phone quote. No repair scope is committed without a written estimate approved by the property owner or manager.
Can repairs be done without disrupting my Ypsilanti tenants or business operations?
Yes in most cases. Commercial roof repairs are conducted from the roof surface — seam repairs, flashing replacement, pipe boot replacement, and drain work all happen above the ceiling with no interior disruption. Protecht schedules commercial repairs around tenant operations and business hours where coordination is requested. For repairs requiring interior access, scheduling is coordinated directly with the property manager or tenant.
Your Ypsilanti Commercial Roof Is Leaking. The Source Is Probably Not Where the Ceiling Is Stained.
Water on a flat commercial roof travels horizontally before it travels down. The interior stain is where the problem became visible — the actual entry point is somewhere on the roof surface, at a seam, a flashing, a penetration, or a drain, that a physical assessment will find. Protecht has served Washtenaw County commercial property owners for 25-plus years. The assessment is free, the written scope is yours before any commitment, and the honest finding — repair or replacement — is what you get every time.
