Commercial Roof Replacements
Complete Roof Replacement Built for Decades
Commercial roof replacements in Kennan for flat roofs, rubber roofs, and tar-and-gravel systems that have exceeded their functional lifespan
When your flat commercial roof has reached the point where insulation is saturated, the substrate is compromised, or recurring leaks cannot be controlled through repair or coating systems, full replacement becomes the most cost-effective solution. Goldstar Roofing & Coatings handles tear-off and replacement for flat roofs, rubber membrane systems, and built-up tar-and-gravel roofs in Kennan. This service is necessary when restoration methods no longer address the underlying structural issues or when the existing roof assembly no longer meets current building codes or energy standards.
Replacement involves removing the existing roof system down to the structural deck, inspecting and repairing any damaged substrate, installing new insulation if required, and applying a new waterproofing membrane designed for long-term performance. The process addresses not just the leaking surface but also any concealed damage that has accumulated over years of water infiltration or thermal cycling. Proper replacement eliminates the recurring maintenance cycle that aging roofs demand and resets your facility's roof life expectancy to 20-30 years depending on the system installed.
Schedule a property evaluation to determine whether your roof requires full replacement or qualifies for restoration methods like coating or fabric reinforcement.
What Changes After a Full Roof Replacement
The replacement process begins with tear-off, which exposes the roof deck and allows us to identify and repair any rot, rusted fasteners, or structural deficiencies that were hidden beneath the old membrane. Once the deck is confirmed sound and any repairs are completed, new insulation is installed to meet current energy codes, followed by the new roofing membrane-whether single-ply TPO, EPDM rubber, or a built-up modified bitumen system. Seams are heat-welded or adhered according to manufacturer specifications, and all penetrations, transitions, and flashing details are rebuilt to current standards.
Once replacement is complete, you'll notice that interior leaks stop entirely, heating and cooling efficiency improves due to updated insulation values, and the roof surface drains predictably without ponding or debris accumulation in low spots. The new system comes with a manufacturer's warranty that covers material defects, and workmanship warranties that protect against installation failures. Your maintenance requirements drop significantly-new roofs typically need only annual inspections and basic debris removal for the first decade of service.
Replacement is more disruptive and costly than restoration methods, but it's the only option when the existing roof assembly has failed beyond surface-level repair. Buildings with multiple leak points, visible sagging, or a roof that's been patched repeatedly without lasting results are strong candidates for full replacement rather than continued repair attempts.
Common Questions About This Service
Commercial property owners typically want to understand the replacement timeline, what systems are available, and how to decide between repair and full tear-off.
How do you decide between roof repair and full replacement?
If the roof substrate is dry, the structure is sound, and leaks are isolated to seams or surface damage, repair or coating is usually viable; if insulation is saturated, decking is soft, or leaks are widespread and recurring, replacement is the more reliable long-term solution.
What roofing systems are available for flat commercial roofs in Kennan?
Options include single-ply membranes like TPO or EPDM, modified bitumen systems, and built-up roofing, each chosen based on budget, building use, and performance requirements in Wisconsin's freeze-thaw climate.
How long does a commercial roof replacement take?
Timeline depends on building size and weather conditions, but most commercial replacements are completed in one to three weeks, with sections closed daily to prevent weather intrusion.
Can a replacement be done without disrupting building operations?
Tear-off and replacement generate noise and vibration, but work is typically scheduled to minimize impact on business hours, and sections are sealed each day to maintain building weatherproofing overnight.
What warranties come with a new commercial roof?
New roofs include manufacturer material warranties ranging from 10 to 30 years depending on the system, plus workmanship warranties that cover installation defects for a specified period after completion.
Goldstar Roofing & Coatings provides detailed proposals that outline tear-off scope, substrate repairs, insulation upgrades, and membrane options so you can make an informed decision based on your facility's needs and budget. Request a site consultation to review your current roof condition and replacement options.
