At a glance: Completed 2026-10-16: damaged shingle area repair on Glengate Estates Drive, O'Fallon, MO 63366. Office: St. Louis, 314-429-6000.
The call on Glengate Estates Drive
Sometimes a roof call is about one spot. On Glengate Estates Drive the damage was confined to a small area on the back slope, roughly two and a half by three and a half feet. The rest of the roof was in serviceable shape, so there was no reason to talk about replacement.
Small does not mean simple. A patch that is only shingles laid over a hole will leak again, so the scope was written to rebuild the area the same way a new roof is built, from the deck up.
What we found in O'Fallon 63366
The damage went through the shingle layers in the defined area on the rear slope. Everything outside that area was left alone.
What the work order shows
- Took off the existing shingles down to the decking in the 2.5 by 3.5 foot damaged area.
- Put down ice and water shield as underlayment in that work area only.
- Built the area back up course by course with three-tab shingles and sealed them.
- Cleaned up and hauled away the related debris.
What a 2.5 by 3.5 foot repair really involves
It is tempting to think a small area means a quick patch. On Glengate Estates Drive the crew treated those few square feet like a miniature new roof. The damaged shingles came off down to bare decking, which let them confirm the wood underneath was solid. A fresh layer of ice and water shield went on that exposed section only, then new three-tab shingles were built back up course by course.
Three-tab shingles have a flat, uniform look, and each course has to line up with the existing rows or the repair stands out. The new pieces were slid under the course above, nailed in the right zone and sealed so the wind cannot get under them.
Signs a back-slope spot needs attention
Damage on a back slope is easy to miss because nobody looks at that side of the house from the driveway. Common clues are shingle pieces in the yard after a storm, granules collecting at the bottom of a downspout, a dark patch that looks different from the rest of the roof, or a small stain on the ceiling of a back bedroom.
Catching it at this size is the best-case outcome. A few square feet is a short, affordable repair. Left alone through a winter, that same spot can soak the decking and turn into a sheathing replacement.

Why some O'Fallon roofs fail in one small spot
Roofs in St. Charles County subdivisions built in the 1990s and 2000s are often in good shape overall, but a single spot can fail for its own reason. A limb rubbing during wind, a shingle that was nailed too high when the roof went on, or foot traffic from a satellite dish or antenna install can all break down a few square feet while the rest of the roof is fine.
That is why we write repairs to the actual damage instead of rounding up. On Glengate Estates Drive the work order spelled out the exact size, two and a half by three and a half feet, and the crew stayed inside that area.
Keeping the rest of the roof healthy
After a repair like this, simple habits help the roof last. Keep gutters clear so water does not back up under the first course, trim branches back from the roofline, and have the roof looked at after any hail or high-wind storm. A small problem caught early stays small, like this one did.
Repair today, plan for tomorrow
A good repair buys time, and time is valuable. For many O'Fallon homeowners, fixing a damaged spot now means the roof can serve several more years while they plan and budget for an eventual replacement on their own schedule instead of in an emergency. When we finish a repair, we tell the homeowner honestly how much life we think the rest of the roof has, so there are no surprises later. On Glengate Estates Drive, the rest of the roof was in serviceable shape, so the repair was the right investment.
Cleanup on a small job
Even a small repair produces old shingles, nails and wrapper scraps. The crew cleaned up and hauled away everything from the Glengate Estates Drive job so the yard, driveway and gutters were left clear. Homeowners in 63366 should expect the same on any job we do, no matter the size.

Questions homeowners ask about this repair
Can a small damaged spot be repaired without replacing the roof?
Yes, when the rest of the roof is sound. The area is opened to the deck, underlayment is replaced and new shingles are woven into the existing courses.
Why use ice and water shield on a small repair?
It is a self-sealing membrane that bonds to the deck and seals around nails, giving the repaired area a second line of defense under the shingles.
Will a repair match my roof?
We match color and style as closely as available material allows and tell you up front if an exact match is not possible.
Do you do roof repairs in O'Fallon and St. Charles County?
Yes. Call our St. Louis office at 314-429-6000 for a free inspection.
Will my insurance cover a small repair?
It depends on the cause and your deductible. Small repairs often cost less than a deductible, so many homeowners simply pay for them directly.
Do you still repair three-tab roofs?
Yes. Three-tab shingles are still used for repairs, and we match the style as closely as available material allows.
