Residential Flat Roof Replacement in Wausau, WI
When a flat section of a house has been patched too many times, the decking under it is soft, or ice has pushed water under it every spring for years, replacing it is usually cheaper than another round of repairs. Replacement is also the chance to fix why it failed. We tear the old roof off to the deck, replace rotted boards, build in slope so water drains to a gutter or scupper instead of sitting, and install a new EPDM, TPO or modified bitumen roof. The most important part is the flashing where the flat roof meets the house: we tie the new roof into the wall and under the siding or shingles above, with ice and water protection in the corners where snow and ice collect, so the flat section stops being the weak spot.

Leaking right now? Protect the inside first
Move inventory, files and electronics away from the drip, shut off power to any light fixture or panel that is getting wet, and put down buckets or plastic. Keep people out from under a ceiling that is sagging with water above it. Don't send staff onto the roof during a storm, in the dark, or when it is icy or snow-covered. Low-slope roofs have skylights, open edges and slick membranes. Then request service: an active leak can usually be dried in temporarily until a permanent repair is possible.

The building, the roof type if you know it, and what is happening: an active leak, a stain, ponding water, storm damage, or a roof that is just getting old. Active leaks go to the front of the line.
Roof Assessment
We walk the roof, trace the problem, check the drains and flashings, and take core samples or moisture readings where the insulation might be wet.
