Quick answer

STL Roof Repair fixes St. Louis roofs by diagnosing the actual source of the water, not the spot on your ceiling. A technician inspects every slope and the attic, photographs the failure, and gives you a free written estimate the same visit. Common repairs include flashing, pipe boots, wind-lifted shingles, valley leaks, nail pops, and rotted decking. Call (314) 429-6000 any hour.

Diagnosis First

The Leak Is Rarely Where The Stain Is

Water travels. It runs down a rafter, along the top of the drywall, and drips out ten feet from where it got in. That is why our technicians inspect the whole roof plane and the attic instead of patching the spot directly above your ceiling stain.

Flashing failures

Where the roof meets a chimney, wall, skylight, or dormer, thin metal does the waterproofing. Step flashing that has pulled loose, rusted through, or was caulked instead of properly woven into the shingle courses is one of the most common leak sources we find in older St. Louis homes.

Pipe boots and vent seals

The rubber collar around your plumbing vents dries out and splits, usually around year twelve to fifteen. It is an inexpensive part that causes expensive interior damage, and it is often the entire answer to a mystery bedroom leak.

Wind-lifted and missing shingles

Straight-line winds break the factory seal strip. The shingle looks fine from the ground but no longer bonds to the course below it, so wind-driven rain gets underneath. We reseal, re-nail, or replace the affected courses.

Valleys and ice dam damage

Valleys carry the most water on your roof, and Missouri freeze-thaw cycles push melt water back under the shingles. We correct the valley detail and add ice and water shield where code requires it.

Nail pops and exposed fasteners

Decking expands and contracts and works nails back out through the shingle above. Each one is a pinhole straight into your attic. We reset them and seal properly rather than smearing tar over the top.

Rotted decking

If water has been getting in for months, the plywood underneath is soft. Shingling over spongy decking guarantees a callback, so we cut it out, replace the sheathing, and rebuild the assembly correctly.

Common Questions

What Homeowners Ask Us

How much does roof repair cost in St. Louis?

Small repairs - a replacement pipe boot, a handful of blown-off shingles, resealing a vent - land at the low end. Costs climb with the size of the failure, the pitch and height of the roof, and whether decking underneath has rotted and has to be cut out and replaced. We do not quote roof repair over the phone from a description, because the thing causing your leak is frequently not the thing you can see. The inspection and the written price are free.

Can you repair just one section instead of the whole roof?

Yes, and often that is the right answer. Sectional repair works well when the rest of the roof still has real service life and the failure is localized - one slope, one valley, one chimney. Where sectional repair stops making sense is when the shingles have gone brittle and lost their granules, because new shingles will not seal against a surface that is already deteriorating and you end up paying twice.

What are the signs my St. Louis roof needs repair?

Look for granules collecting in the gutters, shingles that are cupped, curled, or missing after wind, dark streaks or bubbling on interior ceilings, daylight visible in the attic, nail heads pushing through shingles, and rusted or separated flashing where the roof meets a wall or chimney. Any of those warrant an inspection. Water stains on drywall mean water has already been getting in for a while.

Do you repair roofs you did not install?

Yes. Most of the repairs we run are on roofs installed by somebody else, including roofs put on by companies that are no longer in business. We inspect it, tell you what was done wrong or what simply wore out, and price the fix.

How long does a roof repair take?

A large share of residential repairs finish in a single visit, often in a few hours. Repairs that need decking replaced, structural work, or materials that must be ordered to match your existing shingle take longer, and we tell you that before you commit to anything.
