Not every roof problem calls for a new roof. A small leak or a few lost shingles on a roof with years left is usually a repair. Damage across the whole roof, or a roof at the end of its life, is usually a replacement. Here is how to tell which one you need, what a roof replacement in Rockford IL actually involves, and what it costs.
When a Repair Is Enough
A repair usually makes sense when:
- The damage is in one area, like a few missing or creased shingles after a wind storm.
- A leak traces back to one spot, like a cracked pipe boot or worn flashing around a chimney, wall or vent.
- The rest of the roof still has plenty of life. The shingles lie flat, hold their granules and are not cracking or curling.
If a repair will do the job, we will tell you. See roof repair for the problems we fix most often.
When Replacement Makes More Sense
Replacement is usually the better money when one or more of these is true:
- Age. The roof is near the end of its expected life, and each new fix only buys a little more time.
- Damage across the roof. Hail bruises, heavy granule loss, or curling and cracking on several slopes, not just one spot.
- Repeat leaks. Patches that keep failing, or leaks showing up in more than one place.
- Soft or sagging decking. Spongy spots or a dip in the roofline mean the wood under the shingles needs work, and that wood can only be reached by taking the shingles off.
- Layers. Older houses can hide two or three old layers of shingles. A roof that already has layers stacked up needs a full tear off, not another layer on top.
When a roof is worn out and patches keep failing, we will say so plainly, show you the photos and let you decide.
What a Roof Replacement Actually Involves
A new roof is more than new shingles. Here is what happens on a full replacement:
- Tear off to the deck. Every old layer comes off, down to the wood.
- Deck repairs. We inspect the decking and replace soft or rotted wood. Your written estimate spells out how decking repairs are priced before work starts, and we show you photos of what we find.
- Ice and water shield. A self sealing membrane goes on every eave and in the valleys, where ice dams and heavy runoff are most likely to push water under the shingles.
- Underlayment. The rest of the deck is covered with underlayment as a second layer of protection under the shingles.
- Flashing, drip edge and vents. New flashing at walls, chimneys and valleys, drip edge along the edges, new pipe boots and the ventilation the attic needs.
- Shingles and ridge cap. The shingles go on as part of a complete GAF roof system, installed to the manufacturer’s specs.
- Cleanup. We sweep the yard with magnets and haul everything away.
Most roofs we replace are done in a single day, weather permitting. Steep or complex roofs can take longer, and we tell you that up front.

See insurance claim help.
Repair or Replace FAQ
Can I just put new shingles over my old roof?
Every roof we replace is torn off down to the deck. That is the only way to check and repair the wood underneath and install the ice and water shield, underlayment and flashing the right way.
How do I know if my roof can be repaired instead of replaced?
If the damage is limited to one area and the rest of the roof still has years left, a repair usually makes sense. Damage across the roof, repeat leaks, soft decking or an aging roof usually point to replacement. A free inspection with photos shows you which one your roof needs.
Does insurance pay for a new roof after a storm?
It depends on your policy and the damage. If you file a claim, we can meet your adjuster at your home, review the insurance estimate with you line by line and prepare supplements for anything it missed. You approve every step.
