THE CRYSTAL LAKE ROOFING COMPANY
Roof Replacement in Crystal Lake, IL
When your roof is at the end of its useful life, a full replacement protects your home, lowers your energy bills, and lifts curb appeal for decades to come. The Crystal Lake Roofing Company is an Owens Corning Preferred Contractor specializing in residential roof replacements across Crystal Lake, Algonquin, Lake in the Hills, McHenry, Cary, and the surrounding McHenry County communities.
When Is It Time to Replace Your Roof?
Most asphalt-shingle roofs in northern Illinois last 20 to 30 years. Hail, ice dams, wind, and the freeze-thaw cycles of McHenry County winters all shorten that lifespan. Common signs you need a full replacement instead of a repair include:
- Curling, cupping, or missing shingles across multiple slopes
- Granules in your gutters — a sign the shingle mat is exposed and UV is breaking it down
- Sagging deck or daylight visible through the attic sheathing
- Repeated leaks in different spots after major storms
- Roof age over 20 years on a 3-tab shingle, or 25 years on architectural
- An insurance adjuster has totaled your roof after a hail or wind event
Not sure where your roof stands? We provide free, no-pressure roof inspections with photo documentation so you can make an informed decision.
What's Included in Every Crystal Lake Roof Replacement
We don’t cut corners. Every residential replacement we install is engineered as a complete Owens Corning Total Protection Roofing System — not just shingles. That includes:
- Full tear-off down to the wood deck (no layovers — layovers void manufacturer warranties)
- Deck inspection & replacement of any rotted, soft, or delaminated sheathing
- Owens Corning ProArmor or Deck Defense synthetic underlayment
- WeatherLock ice & water shield on all eaves, valleys, and penetrations (Illinois code requires the first 24″ past the warm wall — we install more)
- Owens Corning Duration® or Duration FLEX® shingles with SureNail® Technology
- VentSure ridge ventilation sized to your attic
- New step flashing, drip edge, pipe boots, and ridge caps
- Magnetic-sweep cleanup of every nail
Because we’re an Owens Corning Preferred Contractor, our completed installs qualify for manufacturer-backed labor and material warranties up to 50 years — something most roofers cannot offer.
