Jacob Roofing Services
Everything we do is roofing. That focus means our Jacob crews install more roofs per year than companies that try to do siding, windows, and remodeling on the side.
Roof Replacement
After tear-off, we always check decking and replace what's needed. Soft spots mean moisture intrusion. The old roof was leaking longer than you realized. We use 7/16" or 15/32" CDX plywood depending on rafter spacing. New decking costs $75-$120 per sheet installed. We only replace what's actually damaged.

We warranty every repair for 5 years. If the same area leaks again due to our workmanship, we come back free. That warranty is in writing and it means something because we're a local Jacob company. We're not disappearing.

Storm damage is time-sensitive. Most insurance policies in Illinois 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.

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.

Standing seam metal with Kynar 500 PVDF fluoropolymer finish. The gold standard for color retention and chalk resistance. We install Sheffield Metals and McElroy Metal panels in 24-gauge Galvalume steel. UL 2218 Class 4 impact resistance (qualifies for insurance discounts in most Illinois markets). UL 790 Class A fire rating. Wind uplift rated to 140+ mph per ASTM E1592 testing. Concealed Z-clips allow thermal expansion without stress on fasteners. That's what makes standing seam leak-proof.

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 Jacob home so you can see them against your siding and trim.

Modified bitumen is the best choice for residential flat roofs and low-traffic commercial applications in Jacob. 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.

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.
Get a Free Quote →Gutter Installation
We hang gutters with hidden hangers screwed into the rafter tails or fascia board every 24 inches max. No spike-and-ferrule, no exposed hardware. Proper pitch is 1/4" per 10 feet toward each downspout. Too flat and water sits. Too steep and it looks wrong.
Get a Free Quote →Roof Inspection
We don't inspect roofs from the ground with binoculars. We get on the roof. Every inspection includes a full walkthrough: shingle condition, flashing integrity, pipe boots, ridge vent, soffit ventilation, gutter function, and visible attic moisture signs. You get photos and a written report.

Storm, wind, hail, or fallen tree. We've handled every kind of roofing emergency in Jacob. 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
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.
