What We Do | Griswold Roofing & Maintenance Roofing Services
Our service list isn't complicated: we fix roofs, replace roofs, and install new ones. We also handle gutters, metal systems, and flat roofing for commercial buildings across Griswold.
Roof Replacement
GAF Timberline HDZ with the full GAF Roof System qualifies your home for the Golden Pledge warranty. That's 25 years on workmanship and 50 years on materials, including algae protection. We install Cobra Snow Country ridge vent with external baffle, FeltBuster synthetic underlayment meeting ASTM D226 Type II equivalent, and Starter Match Pro starter strip. Every component is GAF-approved and inspection-documented.

Improper step flashing is the leading cause of roof leaks at wall-to-roof transitions. Step flashing needs to be woven between shingle courses with each piece extending 4" above the shingle exposure. We see Griswold homes where the last roofer used continuous L-flashing or just caulked the gap. That always fails. We tear it out and install proper step flashing with a kick-out diverter at the bottom per IRC R905.2.8.3.

Not all storm damage qualifies for a full replacement. Hail might only damage one slope. Wind might only lift shingles on the windward side. We document exactly what's damaged and let the insurance company make the call. Honest documentation gets claims approved. Inflated claims get denied.

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

Metal roof repairs are usually sealant failures at transitions, loose panels from improper installation, or rust spots on older galvanized systems. Our Griswold crew repairs all metal types. Not every issue needs a full replacement. Sometimes a sealant touch-up or panel re-securing solves it.

Designer shingles like GAF Camelot II, Owens Corning Berkshire, and CertainTeed Grand Manor mimic premium materials. Slate, cedar shake, heavy wood. They cost 30-50% more than standard architectural shingles but the curb appeal is worth it for higher-end Griswold homes. Full manufacturer warranties included.

PVC membrane for Griswold restaurants, commercial kitchens, and facilities with rooftop grease exhaust or chemical exposure. PVC resists oils and animal fats that destroy TPO and EPDM membranes. We install IB Roof Systems and Duro-Last PVC with factory-fabricated accessories for watertight penetration details. Built-up roofing (BUR) uses 3 or 4 plies of fiberglass felt in hot asphalt with a gravel or cap sheet surface. Oldest proven flat roof system, with 30+ year service life in Iowa. We still install BUR when the application calls for it.

Need a commercial roof coating? Silicone coatings over existing TPO, EPDM, or metal extend life 10-15 years for a third of replacement cost. Not every roof qualifies. The existing membrane needs to be in decent shape. We core sample and moisture scan to verify before we recommend it.

We custom-form seamless aluminum gutters on-site from a continuous coil of .027 gauge stock. No factory seams means no seam failures. We form them to the exact length your fascia requires. One piece, one gutter, no leaks.
Get a Free Quote →Roof Inspection
Our inspection covers the roof and the attic. From the attic, we check for daylight through the roof deck, moisture stains on rafters, mold on sheathing, and ventilation function. Problems in the attic often indicate roof issues that aren't visible from the surface.

Emergency protocol for active water intrusion: (1) interior containment. Buckets, plastic sheeting, water extraction if accessible, (2) exterior tarping with 20x30 heavy-duty poly sheeting over damaged area extending minimum 4 feet past damage on all sides, (3) secure with 2x4 nailer boards lag-screwed to the roof deck (not through shingles), (4) secondary tarp overlap for multi-section damage, (5) document with timestamped photos for insurance. Permanent repair scheduled within 48-72 hours once materials are sourced.
Get a Free Quote →Skylight Installation
Skylight replacement on existing curbs: VELUX FCM curb-mount units install directly on the existing curb frame. No structural modification, no interior disruption. The FCM sits on the curb with a built-in sill pan and integrates with a new QCM flashing kit. Low-E4 laminated glass with argon fill provides R-value improvements over older skylights. Solar-powered blinds and venting available on VSS models. The 10-year No Leak Installation Warranty requires VELUX-certified installation with the complete flashing system. We're certified in Griswold.
