What We Do | Geff 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 Geff.
Roof Replacement
Your roof replacement includes a full-system install: ice and water shield at eaves, valleys, and penetrations; synthetic underlayment across the entire deck; aluminum drip edge at rake and eave; starter strip with sealant; architectural shingles with 130+ mph wind rating; and continuous ridge vent for proper attic ventilation. We also install new pipe boots and vent flashing on every penetration.

We repair asphalt shingle, metal, flat membrane, and tile roofs. Our trucks carry common repair materials so most fixes happen same-visit. Shingle repairs, flashing replacement, pipe boot swaps, ridge cap fixes, valley re-flashing. All routine for our Geff crews.

We handle storm damage claims from start to finish: inspection, documentation, claim filing, adjuster meeting, supplement if needed, repair or replacement, and final inspection. Our supplement team has recovered thousands in additional coverage for Geff homeowners that adjusters initially missed.

New construction underlayment per IRC R905 and ASTM D226 (felt) or ASTM D6757 (synthetic). Ice barrier per ASTM D1970 required at eaves in climate zones with average January temperature below 25°F. We install ice and water shield regardless. It's cheap insurance against ice dams and wind-driven rain. Drip edge per IRC R905.2.8.5 on eave and rake edges. Proper starter strip with factory sealant for wind resistance from day one.

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.

Shingle color matters more than you think. Dark shingles absorb heat. Great for cold Illinois winters, harder on cooling bills in summer. Lighter colors reflect heat. Algae-resistant granules prevent black streaking. We bring shingle samples to your Geff home so you can see them against your siding and trim.

Flat roof leak detection in Geff: we start with a visual inspection of seams, flashings, and penetrations. If the leak source isn't obvious, we use electronic leak detection (ELD) or flood testing on membrane roofs. We find it and fix it. No guessing, no unnecessary tear-offs.

We install Carlisle SynTec and Firestone TPO membrane systems in 60-mil and 80-mil thickness over minimum R-25 polyiso insulation (more in climate zones requiring it). Seams hot-air welded at 900°F+ and tested with a seam probe. Fully adhered systems for wind uplift zones per FM I-90 or I-120. Mechanically attached for re-roofs over existing insulation. NRCA member, trained per manufacturer specifications.

Clogged gutters cause fascia rot, soffit damage, and foundation erosion from concentrated water runoff. That's not a marketing scare tactic. We see the damage on every other gutter replacement in Geff. Properly sized gutters with adequate downspout capacity move water away from the house. We calculate capacity using rainfall intensity data for Geff: roof area x pitch factor x rainfall rate in inches per hour. Standard 5" K-style handles 5,520 square feet of effective roof area.

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 Geff.
