Our roof repair process: inspect the issue, identify the root cause, quote the fix, do the work, warranty the repair. Simple. If the root cause is widespread (poor ventilation causes ice dams, for example), we'll recommend addressing that too. But the choice is always yours.
Get a Free Quote →Storm Damage Repair
Storm damage is time-sensitive. Most insurance policies in Missouri require claims within 12 months. We do a free inspection, document every damaged area with photos and measurements, and help you file the claim. If the adjuster approves it, we handle the repairs at the insurance-approved price.

We handle new construction from permits through final inspection. Our Alton office coordinates with your builder on scheduling, material delivery, and inspection timing. Typical install time is 1-3 days depending on size and complexity.

We install 24-gauge and 26-gauge steel standing seam panels in Galvalume and pre-painted finishes. Concealed fastener clips allow the panels to expand and contract with temperature changes without stress on the fasteners. That's why standing seam doesn't leak. The clips float.

GAF Timberline HDZ. The best-selling shingle in North America. With StrikeZone nailing area for consistent fastener placement. Class A fire rating per UL 790, Class 4 impact resistance per UL 2218 (when installed in the GAF Roof System), and Class H wind rating per ASTM D7158 (130 mph). We install Timberline in the full GAF system to qualify for Golden Pledge warranty: 25-year non-prorated workmanship plus 50-year materials with WindProven limited wind warranty (no max speed). That warranty is why we recommend GAF for most Alton homes.

Modified bitumen is the best choice for residential flat roofs and low-traffic commercial applications in Alton. We torch-apply SBS-modified base and cap sheets in a two-ply system. Granulated cap sheet handles foot traffic and UV exposure. 15-20 year warranty.

Commercial roof maintenance programs keep small problems from becoming big ones. We offer annual and semi-annual inspection contracts for Alton building owners. We find and fix issues before they cause interior damage to your inventory, equipment, or tenant spaces.
Get a Free Quote →Gutter Installation
We install gutter guards for homeowners who are done cleaning gutters twice a year. Micro-mesh over the opening, screwed into the front lip. Leaves and pine needles sit on top and blow off. Not 100% maintenance-free, but close. You might hose them once a year.

Commercial and flat roof inspections include infrared moisture scanning with Flir E8 thermal cameras. Trapped moisture in the insulation layer shows as temperature differentials on the thermal image. No need to cut core samples everywhere. We identify wet zones, then core sample the suspect areas to confirm. This approach gives you a precise repair scope at a fraction of the cost of exploratory tear-offs.

Storm, wind, hail, or fallen tree. We've handled every kind of roofing emergency in Alton. First priority is always preventing further water damage to your interior. Second priority is documentation for insurance. Third is the permanent fix.
Get a Free Quote →Skylight Installation
We install three types of skylights: fixed (sealed, just for light), vented (opens for airflow. Great for bathrooms and kitchens), and tubular (flexible tube through the attic. For tight spaces where a standard skylight won't fit). Each serves a different purpose.
