Full-Service Roofing | Griggsville, IL
Griggsville Roofing & Maintenance handles every roofing job from a single-shingle repair to a full commercial re-roof. Here's what we do in Griggsville.
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.

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 Griggsville 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.

After every major storm in Griggsville, out-of-town companies flood the area offering free inspections. They're not all bad, but many are. We're local, we're licensed, and we'll be here to honor the warranty. Storm chasers won't be.

Proper ventilation is the most overlooked element in new roof installation. We calculate intake and exhaust per IRC R806 based on attic square footage. Balanced ventilation. Soffit intake matched to ridge exhaust. Keeps your attic cooler in summer and drier in winter. That extends roof life and cuts your energy bill.

Metal roofing works on pitches as low as 3:12 for standing seam and as low as 1:12 with specific underlayment and sealant requirements. Steep pitches look incredible in metal. We help you choose the right panel profile, material, and color for your Griggsville home.

Architectural shingles are what we install on 90% of Griggsville homes. They're thicker, heavier, and more wind-resistant than the old 3-tab flat shingles. They also look dramatically better. Dimensional profiles that mimic wood shake or slate. Standard architectural shingles carry a 30-year warranty. Premium versions go to 50.

Flat roofs don't actually drain themselves. That's the challenge. Water ponds, UV breaks down the membrane, and eventually it leaks. We install and repair TPO, PVC, EPDM, modified bitumen, and built-up roofing systems designed for zero-slope conditions in Griggsville.

Your commercial roof has HVAC units, exhaust fans, plumbing vents, and satellite dishes punching through it. Every penetration is a potential leak point. We install prefabricated curbs, custom-welded flashings, and pitch pans that handle foot traffic and thermal cycling without failing.

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 Griggsville. Properly sized gutters with adequate downspout capacity move water away from the house. We calculate capacity using rainfall intensity data for Griggsville: 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.

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.

Fallen tree damage requires immediate structural assessment before tarping. If a tree has displaced rafters, cracked a ridge beam, or pushed through ceiling joists, the structure is compromised. We assess from both exterior and attic, coordinate with structural engineers or framing contractors when needed, and tarp only areas that are structurally stable enough to support the tarp hardware. Insurance claims for tree strikes require separate line items for tree removal, structural repair, and roofing repair. We document each scope independently.
Get a Free Quote →Skylight Installation
VELUX FS (fixed) and VS (vented) skylights installed with EDL flashing kits for shingle roofs. The multi-step flashing integrates with the surrounding shingle courses per IRC R903.2. We frame the curb with doubled 2x8 or 2x10 lumber (depending on rafter depth), install ice and water shield membrane around the entire curb perimeter, then set the skylight with factory sealant before weaving step flashing into the field. Top headwall flashing tucks under the upslope shingle course. Bottom sill pan diverts water onto the downslope shingles. Zero exposed sealant joints. Mechanical flashing only.
