Roof Waterproofing in Duluth, Minnesota

Roof Waterproofing in Duluth means roofing built for the Minnesota climate - the heat, the humidity, and the storms. The Minnesota humidity and the severe storm remnants test every roof, and the tree debris covers the surface.

Signs Your Duluth Roof Needs Roof Waterproofing

• Leaks at the flat roof seams - the seams are the weak point
• Water stains around the vents and the pipes - the penetrations are leaking
• Cracked or brittle sealant - the heat has dried it out
• Ponding water on the flat roof - the drainage and the membrane need work
• The waterproofing is over 10 years old - the membrane has aged

Why Duluth Roofs Need Roof Waterproofing

The storm season is the main reason. The severe storms bring the heavy rain that finds the smallest gaps.

The heat is the second reason. The sun bakes the roof and the expansion and contraction stress the seals.

How We Do Roof Waterproofing in Duluth

1. Inspect the roof and the penetrations - find the gaps and the weak points
2. Clean and prepare the surface - the clean, dry substrate for the membrane
3. Install the waterproof membrane - the liquid-applied or the sheet membrane
4. Seal the penetrations - the vents, the pipes, and the flashing
5. Test the waterproofing - the water test verifies the seal

Preventing Problems in Duluth

• Inspect the sealant each spring - the heat dries out the seals
• Check the penetrations after every storm - the early detection stops the leaks
• Clear the drains and the scuppers - the debris blocks the water flow
• Re-seal on schedule - the fresh sealant keeps the roof watertight

In Duluth, the waterproofing is the barrier against the storm rain. The membrane and the sealant keep the water out of the flat roofs and the penetrations. The annual check and the refresh keep the roof watertight for years.
