Boss Roofing-Siding Experts is a roofing company based in Sterling, Illinois, serving Rock Falls homeowners from just across the Rock River. Because our crews live and work in the Sauk Valley, we can reach Rock Falls homes quickly for inspections, estimates and repairs.
Exterior Remodelers with Roofing, Siding, Window and Gutter Expertise
Our local Rock Falls roofing contractors specialize in roof replacement, roof repair and storm damage restoration, and we also install siding, replacement windows and seamless gutters.
We are a GAF Master Elite Residential Roofing Contractor, a member of the GAF President's Club and a multiple GAF Triple Excellence Award winner. For Rock Falls homeowners, that means your roof is installed by certified roofing contractors who are held to the manufacturer's own standards.
Roof Replacement in Rock Falls
Many Rock Falls homes were built in the mid-twentieth century, and a lot of them are on their second or third roof. When shingles curl, granules wash into the gutters or leaks keep returning, a full roof replacement is often the most cost-effective fix.
Our roof replacement process includes:
- A detailed inspection of the decking, flashing and ventilation before any work begins
- Complete tear-off down to the deck, with damaged boards replaced
- Installation of a full GAF roofing system, including underlayment, starter strips, shingles and ridge caps
- Magnetic sweeps and full cleanup of your yard and driveway
As a GAF-certified installer, we can offer access to GAF's enhanced manufacturer warranty options. Learn more about what our GAF Master Elite certification means for your home.
Roof Repair for Rock Falls Homes
Not every roof problem calls for a new roof. Our roofers repair missing or damaged shingles, failed flashing around chimneys and vents, and leaks at valleys and skylights. We will tell you honestly whether a repair will hold or whether replacement makes more sense. You can explore all of our residential roofing services to see the full range of options.
Siding Installation
The freeze-thaw cycles and humid summers of northern Illinois are hard on older wood and aluminum siding. Our siding contractors install James Hardie fiber cement siding, LP SmartSide engineered wood siding and Versetta Stone. Each product resists moisture, holds paint well and gives your home a fresh, updated look. See how our siding installation process protects your home from the sheathing out.
Replacement Window Installation
Drafty windows raise heating bills through long Rock Falls winters. We are replacement window installation contractors for ProVia, Andersen and Simonton windows and doors. Upgrading to energy-efficient replacement windows can make your home more comfortable year-round and reduce energy costs.
Seamless Gutters and Gutter Guards
Rock Falls has plenty of mature trees, which means clogged gutters every fall. We install seamless gutter systems with gutter guards that keep debris out and direct water away from your roof edge, siding and foundation.
Storm Damage Restoration
Hail and high winds regularly move through the Rock River valley. If a storm has damaged your roof or siding, our team will inspect the damage, document it for your insurance claim and restore your home. Learn how our storm damage restoration service works from inspection to final walkthrough.
