WATERPROOFING
JOLIET ROOFING COMPANY

Waterproofing Services in Joliet, IL

 

In Joliet, one overlooked seam can lead to thousands in water damage. And let’s be honest—once moisture gets under your roof or into your walls, it doesn’t ask permission. It spreads.

​

At Joliet Roofing Company, we don’t wait for leaks to show up. We shut them down before they start. Our waterproofing services are built for the long haul—no weak sealants, no lazy shortcuts. Just high-performance systems that lock moisture out and keep your building safe.

​

​

Why It’s Worth Getting Ahead of Water Damage

Waterproofing isn’t just for when the roof starts dripping. It’s the system you want in place before the storm hits, the snow melts, or the mold shows up. Especially with Joliet’s mix of weather—snow, sun, rain, wind—you need your roof to stay sealed year-round.

When it’s done right, waterproofing:

• Stops leaks before they form

• Extends roof life by 5–10+ years

• Protects insulation and energy performance

• Lowers risk of mold, wood rot, and ceiling damage

​

​

What We Waterproof

• Flat roof surfaces (residential and commercial)

• HVAC curbs, skylight edges, and vent flashing

• Wall-to-roof joints and parapet caps

• Balcony and overhang transitions

• Drains, scuppers, and water-prone valleys

• Masonry cracks or expansion points

​

Waterproofing Systems We Use

 

Reinforced Coating Systems

These systems include fabric embedded between two layers of weatherproofing. They’re strong, durable, and perfect for rooftops that get walked on or support rooftop gear.

​

Flashing Sealants & Wraps

Most leaks start at the seams. We target those weak spots with commercial-grade sealants—and wrap them when needed to make sure they stay sealed under wind, rain, and heat.

​

Liquid-Applied Membranes

Think of it like shrink-wrapping your roof. These membranes go on wet and dry into one solid, seamless shield—no edges, no joints, no gaps.

​

Cementitious Waterproofing

This is what we use on concrete, parapet walls, and brick. It gives a tough, breathable coating that keeps water out but won’t trap moisture inside older masonry.

​

Elastomeric Coatings

Flexible and UV-resistant, these coatings are great for roofs with sun exposure and thermal expansion. They move with the building and keep your surface sealed tight.

​

​

How to Spot a Problem Before It’s Too Late

• Cracking sealant around skylights or pipes

• Water stains near ceilings or upper walls

• Rust marks near rooftop equipment

• Blistered paint or soft interior drywall

• Drains not working properly after rain

• That musty smell you keep trying to ignore

What Will It Cost?

There’s no guesswork here. We inspect your property, look at the surfaces, and figure out exactly what kind of protection you need. If it’s just sealing flashings—great. If it’s a full flat roof system, we plan it out properly.
