Roof Felt Repair: Your Complete 2800-Word Guide to Protecting Your Roof and Home
Roof felt might be out of sight, but it should never be out of mind. Acting as a critical barrier between your shingles and the elements, roof felt (or roofing underlayment) plays a vital role in waterproofing, insulation, and structural protection. Over time, this under-the-shingles material can become worn, damaged, or torn—and when that happens, it can lead to major leaks and even more serious damage.
In this extensive blog, we’ll explore everything you need to know about roof felt repair: what it is, signs of damage, DIY vs. professional fixes, costs, timelines, materials, and more. Whether you live in Jefferson, Ashtabula, Madison, Geneva, Chardon, or other parts of Northeast Ohio, this guide will help you make informed decisions about protecting your home with reliable roof felt repair.
What Is Roof Felt?
Roof felt, also called roofing underlayment, is a protective layer installed between the roofing deck (usually plywood or OSB) and the shingles. Its primary functions include:
- Providing water resistance
- Acting as a secondary barrier if shingles are damaged
- Protecting the decking from condensation and leaks
- Offering some fire resistance (depending on the material)
- Assisting with shingle installation alignment
Roof felt comes in various materials:
- Asphalt-saturated felt (traditional black felt)
- Synthetic underlayment (more modern, durable alternatives)
- Rubberized asphalt (self-adhering, waterproof options)
Why Roof Felt Gets Damaged
Roof felt is designed to be durable, but it doesn’t last forever. It can degrade over time due to:
⛈ Weather Exposure
Extreme heat, cold, snow, and wind can wear down or tear roof felt—especially during storms.
⚡ Improper Installation
Incorrectly overlapped, stapled, or cut felt may lead to gaps that allow water intrusion.
⏱ Age
Like all roofing materials, roof felt breaks down over time, particularly if it’s exposed due to missing shingles.
🚨 Roof Leaks or Damage
Leaks from damaged flashing, vents, or shingles can rot or deteriorate the underlayment.
⚠ Pests
Rodents or insects may chew or nest in your roof layers, causing felt to rip or weaken.
Signs Your Roof Felt Needs Repair
Because roof felt is beneath the surface, detecting damage isn’t always obvious. But here are some common indicators:
- Water spots on ceilings or walls
- Mold, mildew, or rot in the attic
- Missing or damaged shingles
- Sagging areas of roof decking
- Unusual humidity or musty smells in upper rooms
- Recent storm or hail damage
If you see any of these, it’s time to have your roof professionally inspected.
Can You Repair Roof Felt Without Replacing the Roof?
Yes—depending on the location and extent of the damage. Here are a few common scenarios:
Minor Localized Repairs
If a small patch of roof felt is torn or compromised (and shingles above it are still in good shape), a roofing contractor can:
- Remove the shingles in that area
- Cut out and replace the damaged felt
- Reinstall the shingles using proper overlap and sealing
Partial Roof Felt Replacement
If damage is more extensive (e.g., across one side of the roof), a partial replacement may be needed.
Full Roof Replacement
If the felt is failing across the entire roof or if the shingles are also at end-of-life, a full roof replacement is the most cost-effective solution.
How Roof Felt Repair Is Done
Step 1: Roof Inspection
A trusted contractor like S&K Construction and Remodeling LLC starts with a thorough inspection of shingles, decking, and underlayment. We’ll determine the source and scope of the damage.
Step 2: Shingle Removal
Damaged shingles are carefully removed to expose the roofing felt beneath.
Step 3: Cut Away Damaged Felt
The torn or rotted felt is cut out, and the surrounding area is examined for hidden damage.
Step 4: New Felt Installation
A new section of roof felt is installed with correct overlap and fasteners. We typically use synthetic underlayment for greater water resistance and longevity.
Step 5: Re-Shingling
Shingles are replaced with proper sealing and alignment. We make sure your roof looks seamless and maintains its integrity.
DIY vs. Professional Roof Felt Repair
Some homeowners consider tackling small roof repairs themselves. But be cautious: improper repairs can void warranties or create new leaks.
Pros of Hiring a Professional:
- Safety on steep or high roofs
- Proper integration with shingles
- Guaranteed workmanship
- Faster turnaround
- Insurance claim assistance
Risks of DIY Repairs:
- Safety hazards
- Improper material overlap
- Inadequate sealing
- Missed signs of deeper damage
For a small detached garage or shed, DIY may be possible. But for your home, trust professionals like S&K Construction and Remodeling LLC.
