A failing flat roof does not get better with time, it gets worse, and every rainstorm adds another layer of hidden damage underneath. Chronic leaks, blistering membranes, and cracked surfaces are not problems you patch your way out of forever. At some point, replacement is the only decision that protects your home and your wallet. Perrault Roofers specializes in complete flat roof replacement built for Wisconsin’s harshest seasons, delivered with honest pricing and workmanship that holds up when it matters most. If your roof is past saving, we make the replacement fast, clean, and permanent.
Chronic leaking, surface cracking, blistering, and widespread membrane failure are signs your flat roof has reached the end of its usable life. Continuing to repair a roof in this condition only delays the inevitable while your structure absorbs more damage underneath. Perrault Roofers handles complete tear off, substrate inspection, and full system installation with precision and speed. We minimize disruption to your household while maximizing the lifespan and performance of your new flat roofing system, so you get decades of protection instead of another emergency call next season.
Every replacement is only as strong as the installation behind it. That is why we approach each new flat roof with meticulous attention to drainage design, membrane sealing, and flashing detail. Poor workmanship is what creates ponding water and chronic leak points in the first place, and we refuse to repeat those mistakes. Our installations follow industry best practices using top quality materials selected specifically to perform under Wisconsin’s demanding climate conditions.
Not every issue requires a full replacement. Caught early, most flat roof problems can be resolved with targeted, cost effective repairs. We diagnose the true source of leaks, membrane splits, flashing separations, and drainage failures accurately before recommending any solution. If your roof can be saved without a full tear off, we will tell you honestly, and repair it to last through Superior’s harshest seasons.
For roofs that are not quite ready for replacement, professional waterproofing and coating systems add a reinforced barrier against moisture intrusion, UV degradation, and thermal movement. This gives your flat roof a second wind and buys additional years of protection, delaying the cost of full replacement without sacrificing performance.
Years of hands-on roofing expertise ensure every project is done right the first time.
We use trusted, industry-leading materials for long-lasting durability and performance.
No hidden costs—just clear estimates and straightforward communication.
We complete projects on time while maintaining the highest quality standards.
