ROOF LEAK REPAIR
A leaking roof gets worse every day. We track down the source, fix it permanently, and make sure it doesn't come back.
Roof Leak Repair in Denver, Colorado
A water stain on your ceiling. A drip during heavy rain. A musty smell in the attic. These are all signs your roof is leaking — and every day you wait, the damage spreads. Water travels unpredictably inside your roof structure, soaking insulation, rotting wood framing, and creating ideal conditions for mold growth.
At The Roofing and Siding Company, we specialize in finding leaks at their source — not just where the water appears. Our systematic inspection process traces the leak back to its origin point, and our repairs are designed to eliminate the problem permanently.
Common Causes of Roof Leaks
- Damaged Flashing: Metal flashing around chimneys, skylights, walls, and valleys is the #1 source of roof leaks. Over time, flashing corrodes, lifts, or separates from surfaces, creating a direct path for water entry.
- Failed Pipe Boots: Rubber boots around plumbing vents crack and deteriorate after 10–15 years of UV and temperature exposure, creating gaps around every pipe penetration on your roof.
- Worn or Missing Shingles: Wind, hail, and age cause shingles to crack, curl, or blow off entirely, exposing the underlayment and decking to direct water contact.
- Valley Failures: Roof valleys channel large volumes of water. When valley flashing or shingles fail, the concentrated water flow causes rapid damage.
- Ice Dam Damage: Denver's freeze-thaw cycles create ice dams along the eaves that force water underneath shingles and into the roof deck and attic.
- Skylight Seal Failure: Skylights are surrounded by flashing and sealant that degrades over time. Even well-installed skylights can develop leaks after 15–20 years.
- Clogged Gutters: When gutters back up, water pools along the roofline and wicks underneath shingles, especially during heavy Colorado downpours.
Our Leak Detection & Repair Process
- Interior Inspection: We start by examining water stains, drip locations, and attic conditions to understand the symptom pattern and narrow down the leak zone.
- Exterior Roof Inspection: We systematically inspect the suspect area — checking shingles, flashing, penetrations, valleys, and vents for any signs of failure.
- Source Identification: We trace the leak to its true origin. Water can travel 10+ feet along a rafter before dripping, so the visible stain is rarely directly below the entry point.
- Repair Plan: We explain exactly what failed, how we'll fix it, and provide a written estimate. If insurance applies, we document everything for your claim.
- Permanent Repair: We fix the root cause — not just the symptom. Whether it's replacing flashing, installing new pipe boots, patching shingles, or re-sealing penetrations, we use manufacturer-spec materials that last.

Roof Leak Repair FAQ
How do I find where my roof is leaking?
Roof leaks are tricky — water often enters at one point but travels along rafters, sheathing, or insulation before appearing as a stain or drip somewhere else entirely. Common entry points include damaged flashing around chimneys and skylights, cracked pipe boots, worn valley shingles, and failed sealant. A professional inspection is the most reliable way to trace the leak to its actual source.
Can a roof leak be repaired or does the whole roof need replacing?
Most leaks can be repaired without a full replacement, especially if your roof is relatively new and the damage is localized. Common repairs include replacing damaged shingles, re-sealing flashing, replacing pipe boots, and patching small areas of damaged underlayment. We'll give you an honest assessment during your free inspection.
How much does it cost to fix a roof leak in Denver?
Simple leak repairs (replacing a few shingles, re-sealing flashing) typically cost $300–$1,000. More complex repairs involving multiple penetrations, valley work, or decking replacement can range from $1,000–$4,000+. We provide a detailed written estimate after your free inspection — no surprises.
Is a small roof leak a big deal?
Yes. Even a minor leak that only drips during heavy rain is causing damage you can't see — wet insulation loses its effectiveness, wood framing begins to rot, and mold can grow within 24–48 hours of sustained moisture. A $500 repair today prevents a $10,000+ problem later.
My ceiling has a water stain but I don't see a drip. Is my roof leaking?
Likely yes. A water stain means moisture entered at some point. The leak may be intermittent (only during heavy rain or certain wind directions) or the entry point may have temporarily sealed with debris. It's important to get a professional inspection before the next rain event reactivates the leak and causes more damage.
