Roofing

Architectural shingle and metal roof replacement for Northern Illinois homes and businesses.

Roofing

Services

A roof replacement done to the manufacturer's spec

A shingle warranty only means something if the roof is installed exactly the way the manufacturer requires — the right underlayment, the right nailing pattern, proper ventilation, and correct flashing at every penetration. That's where we're careful, because that's where roofs fail early.

We install architectural asphalt shingles and standing-seam metal for homes, plus flat and low-slope systems for commercial buildings.

What's Included

Every roof replacement includes

★ ★ ★
  • Complete tear-off down to the decking (we don't roof over old shingles)
  • Decking inspection — soft or rotted plywood replaced and itemized
  • Ice-and-water shield at eaves, valleys, and penetrations per Illinois code
  • Synthetic underlayment across the full deck
  • New drip edge, valley metal, and step/counter flashing
  • Manufacturer-matched ridge and intake ventilation for a balanced system
  • New pipe boots, and chimney re-flashing as needed
  • Full ground cleanup with rolling-magnet nail sweep, and a workmanship warranty in writing

Our Process

Tear-off to final magnet sweep

★ ★ ★
  1. Free roof inspection

    We get on the roof, photograph the shingles, flashing, vents, and attic, and show you what we find.

  2. Estimate & shingle selection

    A written, line-item quote with your shingle line and color, ventilation plan, and warranty terms.

  3. Permit & scheduling

    We pull the permit where required, order materials, and set a start date with a weather backup.

  4. Property protection

    Tarps over landscaping and AC units, plywood on delicate areas, and vehicles moved clear of the drip line.

  5. Tear-off & dry-in

    Old roof removed, deck inspected and repaired, then underlayment and ice-and-water down the same day so the house is never exposed overnight.

  6. Install, inspect & warranty

    Shingles, flashing, and ventilation installed, then a full cleanup, a nail sweep, and a walk-through before you get your paperwork.

Questions

Roofing: common questions

★ ★ ★
How do I know if I need a replacement or a repair?

Age, the condition of the shingle mat, and how widespread the damage is. If your roof is under ~15 years old with isolated damage, a repair usually makes sense. We'll tell you honestly which one you're looking at.

Do you help with storm and hail insurance claims?

Yes. We inspect for storm damage, document it the way adjusters need, and meet your adjuster on-site. See our Insurance Claims and Storm & Hail Damage pages.

What happens if it rains during my roof replacement?

We dry-in each section the same day it's torn off, so the house is protected overnight. If weather moves in, we tarp and pause rather than rush.

How long is the workmanship warranty?

We provide a written workmanship warranty on every roof in addition to the manufacturer's material warranty. Exact terms are on your estimate.
