Full Roof Replacement and New Installation in Metro Detroit

Skipping a documented Exterior Maintenance Program can jeopardize many commercial flat-roof warranties because manufacturers often require routine inspections and proof of upkeep to keep coverage valid. The most common denial reason we see is neglect-related damage, like ponding from clogged drains or small openings that weren’t addressed in time.

In our work around Pleasant Ridge, we frequently help building owners align their maintenance logs with the exact forms their roof manufacturer expects.

To stay compliant, keep clear records of:

• Semiannual roof inspections plus post-storm checks
• Drain and gutter cleaning with dates noted
• Minor repairs (seams, flashing, penetrations) with invoices
• Photo logs showing conditions before and after service
• Fast reporting of leaks with temporary mitigation steps

Four Seasons Kanga Roof offers customizable maintenance programs and documented checkups that support warranty requirements without adding hassle. Always read your specific warranty booklet, since terms differ by manufacturer and roof system.

PVC roofing is recommended for restaurants and facilities with rooftop grease or chemicals because PVC resists animal fats, oils, and many chemicals, and its heat-welded seams create durable, watertight joints. Most failures on food-service roofs start when grease softens or embrittles other membranes, leading to seam splits and ponding leaks. PVC stays stable around exhaust fans, tolerates frequent wash-downs, and cleans without absorbing residue. In our experience serving the Rochester area, roofs that see constant fryer exhaust typically last longer with PVC than with non–grease-resistant systems. A veteran tech knows that if you can smell the kitchen on the roof, the membrane is being exposed every day. If you have TPO or modified bitumen, use proper grease containment; if exposure is heavy, consider a PVC overlay or full replacement. Have a qualified roofer inspect the membrane and the grease path from the fan before the next cleaning cycle.

Four Seasons Kanga Roof protects your employees and customers during a major roof tear-off by focusing on site control, debris management, and thorough cleanup throughout the job. Most risks come from falling debris and conflicts where customer foot traffic meets active work. Our trained crews and dedicated project management keep operations organized and monitored, and our Nail Free Guarantee reflects our commitment to leaving the ground clear of hazards. This disciplined approach is the same process we bring to projects in and around the Washington Township area.

Standard roof-safety measures typically include:

• Clearly defined work zones with controlled access and on-site supervision
• Tear-off sequencing that avoids your peak customer hours when feasible
• Protective coverings at entrances and sensitive areas to reduce dust and debris
• End-of-day and final cleanup aimed at eliminating stray nails

Please coordinate site access points with our project manager in advance so we can keep people away from active tear-off zones. <br/> Updated: 2026-05-07 <br/> Need help in Washington Township, MI?

A commercial tear-off costs more than a layover because you’re removing old roofing down to the deck, which adds labor, disposal, and often structural repairs that a layover avoids. The biggest cost jumps usually come from uncovering hidden issues like wet insulation or damaged decking once the old system is off. On flat roofs with HVAC penetrations, each curb, pipe, and edge transition must be re-flashed from scratch, which increases time and materials. Code-required upgrades can also trigger during tear-off, while layovers often defer them. On many flat roofs around New Baltimore, we find trapped moisture that isn’t visible until removal.

Watch for these cost drivers during estimating:

• Extra layers to remove and haul, plus landfill fees
• Saturated insulation requiring full replacement
• Rusted or rotted decking that needs new panels
• Replacing edge metal and re-flashing numerous penetrations

Ask for a core sample and on-roof inspection to verify layers, moisture, and deck condition before you set a budget. <br/> Updated: 2026-05-07 <br/> Need help in New Baltimore, MI?

If a roofing contractor damages rooftop HVAC units during a tear-off, the contractor is generally responsible and their liability insurance should cover repair or replacement. Most damage happens when pry tools or tear-off machines strain refrigerant lines or the metal curb flashing that seals the unit to the roof. Pause work, document everything, and coordinate a joint inspection so cause and scope are clear. Four Seasons Kanga Roof regularly handles flat/TPO and metal roofs with HVAC penetrations across the Detroit area, so we plan tear-offs to protect line sets and curbs before demo begins.

What to do right away:

• Stop work at the area and notify the project manager in writing with photos.
• Keep the unit powered down at the disconnect to avoid compressor damage.
• Request a joint roof/HVAC assessment and temporary weatherproofing around the curb.
• Ask for proof of insurance and put agreed repairs in a signed change order.

Keep serial numbers and service reports together to speed any insurance claim. <br/> Updated: 2026-05-07 <br/> Need help in Warren, MI? Call (586) 300-4163 or book online. "The crew did a great job with the tear off and installation of our new roof." — Christian C.

The best flat roofing for a Metro Detroit building depends on use, exposure, and budget; TPO, PVC, and EPDM each excel in different conditions. Most decisions come down to chemical exposure, foot traffic, reflectivity needs, and how the roof drains. A trained installer will also look at roof deck type and attachment method, since those affect wind performance and long‑term seams. Our team installs flat systems across Metro Detroit and can align the membrane to your building’s daily demands. For commercial replacements, a free 20‑year full system warranty may apply to complete projects; terms apply.

Consider these quick fit‑guides:

• TPO: white, reflective, heat‑welded seams; popular for energy‑minded facilities.
• PVC: strong against grease and chemicals; favored near restaurant or industrial vents.
• EPDM: proven rubber with broad temperature tolerance; simple layouts benefit from fewer seams.

Have a pro confirm deck condition, insulation, and drainage before choosing a membrane. <br/> Updated: 2026-05-07 <br/> Need help in New Haven, MI? Call (586) 300-4163 or book online. “Great service, speedy, and high quality roof replacement on our 8,700 sqft building.” — Michael L.

Both systems work on commercial roofs: pick single-ply (TPO/PVC) for a factory-made sheet with welded seams, or spray polyurethane foam (SPF) for a seamless layer that adapts to irregular surfaces. The biggest driver is your current roof’s condition and how the building is used day to day. A pro will check deck type, trapped moisture, drainage, and service traffic before advising repair or full replacement. On older roofs packed with equipment, I watch how water sits at curbs before I recommend a path. Our commercial team regularly handles flat roofs and TPO projects across the Ray area. For commercial complete replacements, we also offer: “FREE 20-Year Full System Warranty with Every Complete Roof Replacement!”

Use these quick signals to steer the choice:

• Single-ply: clean layout with clear tie-ins at edges and walls.
• SPF: irregular surfaces or many penetrations where a monolithic layer simplifies detailing.
• Either: when budget, warranty, and code align after a core cut and moisture scan.

Schedule an on-roof inspection and test cuts to confirm substrate and moisture before selecting the system. <br/> Updated: 2026-05-07 <br/> Need help in Ray, MI? Call (586) 300-4163 or book online. "Great service, speedy, and high quality roof replacement on our 8,700 sqft building." — Michael L.

Mechanically attached and fully adhered flat roofs differ in how the membrane is held down: fully adhered is typically safer in high winds and on complex layouts, while mechanically attached can be safe and cost‑effective on suitable decks. Most decisions come down to wind exposure, deck type, and how much foot traffic the roof sees.

Mechanically attached uses rows of fasteners through the membrane into the deck; fully adhered bonds the membrane to the insulation or deck with adhesive for continuous hold. On many Southeast Michigan buildings, we see adhered systems reduce flutter and noise, which helps long‑term seams. A technician will check deck pull‑out strength, parapet height, and perimeter details; that’s where the right choice becomes clear.

Choose based on these common signals:

• Fully adhered: higher wind zones, odd shapes, or lightweight decks
• Mechanically attached: sound steel/wood decks, faster dry installs, budget focus
• Either: when uplift engineering shows both meet design pressures

Ask for a site-specific wind‑uplift review and deck fastener test before you decide. <br/> Updated: 2026-05-07 <br/> Need help in Bloomfield Hills, MI?

Thirty thousand dollars for a complete roof replacement is sometimes appropriate and sometimes high, depending on roof size, material, and scope. The biggest drivers are large roofs, premium systems like metal or TPO, and any needed wood-deck replacement. In jobs we see around Oakland Township, MI, complex layouts with steep slopes or many valleys also raise labor and disposal time. A $30k bid should be checked apples-to-apples to confirm it includes full tear-off, modern underlayment, proper ventilation, flashing, and thorough cleanup. If another contractor proposes a truly comparable system for less, we have an Apples to Apples Low Price Guarantee that matches it and beats it by $50.

Signals that $30k is justified:

• Very large roof footprint or multiple structures
• Premium materials (metal/TPO) or upgraded shingles
• Significant decking replacement or rot repair
• Many skylights, chimneys, or mixed flat/steep sections

Ask for a detailed, line-item scope and compare at least two written proposals before you decide. <br/> Updated: 2026-04-16 <br/> Need help in Oakland Township, MI? Call (586) 300-4163 or book online. "The crew did a great job with the tear off and installation of our new roof." — Christian C.

There isn’t a single price per 1,000 sq ft. Cost depends on shingle type, tear-off vs re-roof, roof pitch, and any add-ons. We confirm pricing after an on-site inspection and measurement. You can choose shingles, metal, or specialty systems. Underlayment, vents, gutters, skylights, and insulation affect cost. Financing is available, including 0% options for 6 months to 5 years. Whole-home shingle replacements may include 50% off gutters and gutter guards.

Roof replacement for a 1,500 square foot home is confirmed only after an on-site inspection by Four Seasons Kanga Roof because material type, tear-off needs, decking condition, and roof complexity determine the final price. The biggest swing we see on homes this size comes from hidden wood decking repairs discovered after removing old shingles. We routinely handle shingle, metal, and flat/TPO systems, and we replace roofs across the Sterling Heights area with full system components installed to spec. Financing is available, including 0% programs from 6 months to 5 years for repairs and replacements.

Key factors that change the price:

• Roofing system selected (shingle, metal, or TPO)
• Number of tear-off layers and disposal requirements
• Decking replacement, chimney/valley flashing, and skylight details
• Roof pitch, stories, and penetrations that affect labor time

A complete roof installation cost is based on your roof’s size, design, and chosen system, and it’s confirmed after an on-site inspection. The biggest driver is the overall scope of work from tear-off through the new components and finishing details. When a roof is near end of life or leaking in multiple sections, replacement often costs less long term than repeating repairs. Our team regularly installs shingle, metal, and flat/TPO systems in the Birmingham area. A common surprise is hidden decking or moisture damage found during tear-off, which can change the final price; financing and seasonal instant rebates (for example, $2,000 off eligible whole-home replacements) are available.

Watch for these cost factors during your estimate:

• Roof square footage and waste factor
• Material choice (shingle, metal, TPO) and warranty level
• Pitch, stories, and layout complexity
• Decking replacement, flashing details, and ventilation/code upgrades

A commercial flat roof replacement in Metro Detroit is custom-priced after an on-site assessment; final cost varies by roof system, scope, and building conditions. The biggest cost drivers are the membrane type (such as TPO or metal details) and required insulation thickness to meet code and performance.

Our teams regularly bid and install large flat roofs across the region, from 5,000 to 100,000+ square feet. Typical proposals account for deck condition, penetrations like HVAC curbs, drainage design, safety/access, and any tear-off or overlay strategy. A seasoned estimator will often core the roof to verify layers and moisture before finalizing numbers. For value protection, we offer an Apples to Apples low price guarantee and beat a comparable system quote by $50. The fastest way to get an accurate figure is to schedule a roof evaluation with measurements, cores if needed, and a defined scope.

• Key factors that move price: tear-off vs. overlay, tapered insulation/drainage needs, number of penetrations, deck repairs, edge/parapet details.
• What signals replacement over repair: widespread moisture in insulation, failing seams, trapped water, or structural deck issues.
• What improves pricing clarity: recent drawings, leak history, access notes, and desired warranty term.

Always request a written scope with materials, insulation R-value, and warranty terms before you approve work. <br/> Updated: 2026-05-07 <br/> Need help in Birmingham, MI?

A professionally installed TPO or EPDM roof lasts as long as its design, installation quality, and maintenance allow, not a fixed number of years. Most premature failures start at drainage and flashing details, not in the field membrane. Our crews regularly install and maintain flat roofs across Macomb and Oakland County, so we focus on build quality and upkeep over guesses about age. We also offer customizable roof maintenance programs, and for complete commercial replacements, a FREE 20-Year Full System Warranty is available (conditions apply).

Key lifespan drivers to verify on your roof:

• Membrane thickness and seam welding quality
• Insulation attachment, fastener patterns, and edge securement
• Slope and drainage to keep water moving
• Sun, wind, and temperature exposure
• Foot traffic paths and protection boards
• Penetrations and flashing around HVAC and curbs

Schedule a professional inspection to baseline condition, catch small issues early, and plan the right repair-or-replace timeline. <br/> Updated: 2026-05-07 <br/> Need help in Romeo, MI?

A 50,000 sq ft flat roof replacement is typically completed in planned phases over multiple days to weeks, with the exact schedule confirmed after an on-site inspection. Duration mainly depends on roof system choice (TPO/metal), the number of penetrations, needed deck repairs, weather, and site access. Our commercial crews handle large and complex flat systems and use dedicated project management to sequence sections, manage logistics, and maintain safe access while work is underway. Reviews also note thorough cleanup and efficient tear-off and installation on prior projects. For qualifying commercial complete replacements, a free 20-year full system warranty is available.

On occupied buildings, common steps we plan to reduce impact include:

• Phased sections so only part of the roof is active at a time.
• Clearly marked access routes and safety zones for tenants.
• End-of-day cleanup to promptly reopen walkways and parking.

Replacing a shingle roof yourself safely is a high‑difficulty, high‑risk job that most homeowners should not attempt. The biggest challenges are working at height with real fall hazards and installing a complete, watertight roofing system the right way. A roof is more than shingles; it involves tear‑off, deck repair, underlayment, flashing, ventilation, and precise nailing patterns that require training and the right tools. Errors often show up months later as leaks or voided warranties, not on install day. Our crews serving the Warren area manage removals, full‑system installation, and cleanup as a coordinated process. A small pro move: we stage materials to avoid loading weak spans and time underlayment to beat incoming weather.

DIY becomes especially unsafe or impractical when you face:

• Steep or two‑story slopes that need fall protection and staging
• Multiple layers to tear off or soft/rotten decking
• Valleys, chimneys, skylights, or walls needing custom flashing
• Low‑slope sections that require different membranes and details

If you’re unsure, schedule a roof inspection first and use the findings to choose repair, replacement, or short‑term monitoring. <br/> Updated: 2026-05-07 <br/> Need help in Warren, MI?

Ponding water destroys a flat roof by adding constant weight, accelerating membrane wear from sun and heat, and pushing moisture into seams and penetrations; drainage is fixed by restoring slope and giving water a clear way off the roof. The most common causes are inadequate pitch and obstructed drains or scuppers, often worsened by settled insulation or a sagging deck. A maintenance plan with scheduled inspections helps prevent clogs and early membrane damage. Our team corrects drainage on TPO and other flat systems throughout the Clawson area using standard, durable methods. If water still stands or leaks appear, move from patching to a drainage correction rather than another spot repair.

When an inspection shows trapped water, typical fixes include:

• Clear and resize scuppers and drains; add strainers and proper leaders.
• Install tapered insulation crickets and saddles to push water to drains.
• Add or relocate drains/scuppers where slope is missing.
• Rebuild low spots, replace wet insulation, and reset curb/flashing details.

If ponding lasts more than a day or two, or you see deck deflection or active leaks, schedule service now to prevent structural and interior damage. <br/> Updated: 2026-05-07 <br/> Need help in Clawson, MI?

A white TPO roof typically performs better at limiting summer heat buildup, while a black EPDM roof can be more stable in deep cold; in Michigan’s extreme climate swings, the better choice depends on your building’s heating/cooling demands and roof conditions. Most homes and facilities benefit from TPO’s reflective surface during hot spells, but EPDM’s dark membrane can help melt light snow and is known for cold-weather flexibility on flat roofs. Our crews install both systems across Southeast Michigan and match the membrane to the structure, insulation, and drainage plan rather than climate alone. One installer’s note: on flat roofs with sun after snowfall, darker membranes often clear faster around drains.

Consider these quick decision signals:

• Choose white TPO for cooling-dominant buildings, high sun exposure, or energy-code reflectivity needs.
• Choose black EPDM for proven cold tolerance, simple details, or when budget and long runs favor a single sheet.
• Prioritize whichever system pairs best with insulation, slope, and drain layout.

Ask a pro to evaluate insulation, deck condition, and ponding risk before you decide. <br/> Updated: 2026-05-07 <br/> Need help in Washington, MI?
