A flat roof that fails is not a minor inconvenience, it is a direct threat to everything under your ceiling. Ponding water, hidden leaks, and membrane breakdown turn small problems into five figure repairs fast. Perrault Roofers exists to make sure that never happens to your home. We are Superior’s dedicated flat roofing specialists, and every installation, repair, and coating job we complete is engineered to survive Wisconsin’s brutal freeze thaw cycles without compromise. If you want a flat roof that performs for decades instead of failing in year five, you are already in the right place.
Your flat roof is only as strong as the crew that installs it. Sloppy drainage design and rushed membrane sealing are the two biggest causes of premature failure, and they are entirely preventable. Perrault Roofers installs every flat roofing system with precise pitch calculations, sealed seams, and flashing detail that actually holds. We use top tier materials chosen specifically to withstand Wisconsin’s demanding climate, so your investment is protected from day one.
Chronic leaks, surface cracking, blistering, and widespread membrane failure are not signs to patch and pray. They are signs your roof is done, and continuing to repair it is throwing money away. Our team executes complete tear off, substrate inspection, and full system replacement with speed and precision. We work clean, we work efficiently, and we deliver a roof built to maximize lifespan, not just pass inspection.
Caught early, most flat roof issues can be resolved without a full replacement, but only if the diagnosis is correct. We identify the true source of leaks, membrane splits, and flashing separations, then repair them with lasting precision. No temporary patches that fail at the first hard freeze. Our repairs are built to hold through Superior’s harshest seasons, not just until next quarter.
Extend the life of your existing flat roof without paying for a full replacement. Our professional waterproofing and coating applications add a reinforced barrier against moisture intrusion, UV degradation, and thermal movement. It is the smartest way to protect your property investment and buy your roof years of additional performance.
