Roof Waterproofing in Milwaukee

Sealing your roof system against Wisconsin rain, snow, and ice.

A waterproof roof requires more than just good shingles — it demands proper underlayment, sealed flashing, functioning drainage, and quality workmanship at every penetration point. Holland Exteriors provides comprehensive waterproofing solutions including ice-and-water shield installation, membrane application for flat roofs, flashing sealing, and coating systems that add an extra layer of defense against Wisconsin precipitation. Our systematic approach addresses every potential water entry point for total protection.

How Roof Waterproofing Connects to Your Overall Roof Health

Roof Waterproofing is one part of keeping your Milwaukee home protected. Many homeowners who need roof waterproofing also benefit from flat roofing, roof flashing and leak detection — addressing these together prevents recurring issues and often saves money compared to handling them separately.

Whether your home is in Milwaukee, Racine, or Shorewood, our team provides comprehensive assessments that identify all issues at once — so you can prioritize based on urgency and budget rather than discovering problems one at a time.

Roof Waterproofing FAQ

What does roof waterproofing include?

Roof waterproofing encompasses ice-and-water shield along eaves, valleys, and penetrations; sealant application at all flashing joints; membrane systems for flat sections; and coating applications for added protection. The specific scope depends on your roof type and vulnerable areas.

Is ice-and-water shield necessary in Wisconsin?

Absolutely. Wisconsin building code requires ice-and-water shield from the eave edge to at least 24 inches past the interior wall line. We recommend extending it further in valleys and around penetrations for maximum protection against ice dam backup.

How long does roof waterproofing last?

Ice-and-water shield lasts the life of your roof. Sealant applications typically last 5 to 10 years depending on exposure. Flat roof coatings last 10 to 15 years. We inspect waterproofing elements during maintenance visits and recommend reapplication when needed.
