What does roof waterproofing actually involve? Waterproofing is the process of sealing your roof and its components against water intrusion. It covers everything from the membrane and flashing to the joints, seams, and penetrations around vents and chimneys.
A properly waterproofed roof keeps moisture out no matter how hard it rains. It protects your home from the inside out and extends the life of your roofing system.
Our waterproofing services include:
- Roof membrane waterproofing
- Flashing sealing and replacement
- Joint and seam sealing
- Chimney and vent waterproofing
- Foundation and wall waterproofing
- Flat roof waterproofing systems

Weatherizing Services in Bourbonnais, IL
What is weatherizing, and how is it different from waterproofing? Weatherizing focuses on sealing your home against air, cold, and heat loss. It works alongside waterproofing to create a full barrier against the elements. Together, they keep your home comfortable and your energy bills in check.
In Illinois, winters are long and cold. A weatherized roof and attic make a big difference in how well your home holds heat. Our team identifies weak spots and seals them up before the season hits.
Our weatherizing services include:
- Roof and attic air sealing
- Insulation checks and upgrades
- Soffit and fascia sealing
- Weatherstripping around roof penetrations
- Ice dam prevention
- Caulking and sealant application
- Pre-winter roof inspections


Frequently Asked Questions
What is the best time of year to weatherize a roof?
Late summer or early fall is ideal. That gives you time to address any issues before the cold season sets in.
How do I know if my roof needs waterproofing?
Look for water stains on your ceiling, peeling paint near the roofline, or damp spots in your attic. Any of these are signs that moisture is getting in.
Can waterproofing stop an active leak?
In some cases, yes. But first we need to find the source. We'll inspect your roof, identify the problem, and recommend the right fix.
What is an ice dam, and how does weatherizing help?
An ice dam forms when heat escapes through your roof and melts snow, which then refreezes at the eaves. Proper insulation and air sealing prevent heat from escaping in the first place.
