Your roof is one of the most important parts of your home. As the first line of defense against weather and other elements, a worn or damaged roof can lead to a variety of issues – from leaks and water damage to mold and rot. Knowing when it’s time for roof repair or replacement is important to maintaining your home’s structural integrity.
Signs You Need Roof Work Done
There are several telling signs that indicate when you need roof repair or replacement:
Leaks
The most obvious red flag is leaks. If you have stains on your ceiling, moisture in your attic, or water dripping after a storm, it likely means your roof is compromised and needs repair or replacement. Even a single leak indicates your roof’s ability to protect your home is failing.
Granule Buildup
Asphalt shingles are covered with ceramic granules to add durability and protect their waterproof asphalt base. When excessive granules end up in your gutter and downspouts, it shows your shingles are actively degrading. Having some granule loss over your roof’s lifetime is normal. But quick degradation with heavy granule loss indicates your shingles are near failure.
Cracked, Curling, or Missing Shingles
Like the excessive granule buildup, curling and cracking shingles demonstrate your roof is weakening. As the material degrades, shingles lose their shape and structural integrity. This accelerates water penetration and shingle loss, rapidly worsening leaks until replacement. Missing shingles also create openings for water intrusion that will worsen over time.
Moss Growth
If moss takes root and spreads across your roof’s surface, your shingles likely need to be replaced. The moss retains moisture against your roof, worsening leaks while its tendrils dig into and break down the shingle grains. This leads to accelerated deterioration and provides routes for water infiltration. Addressing moss growth through roof repair or replacement is the only way to stop additional damage.
Rotted Roof Sheathing (Decking)
Underneath your shingles are wooden roof decking (or sheathing) panels. Their purpose is to provide a rigid surface that securely anchors each shingle. If water penetrates through damaged, missing, or deteriorating shingles it can lead to soft, dark, rotting spots on your roof decking. This indicates your roof’s defense has already failed and water is infiltrating the substructure. Replacement is needed before the damage spreads.
Attic Stains or Discoloration
Moisture that penetrates your compromised shingles can leak through small gaps or cracks in your roof decking as well. In your attic, this shows up as dark stains or discoloration on the underside of the wooden decking. Like rotted decking, it’s a clear sign moisture is penetrating your roof’s layers and causing substructure damage. Attic moisture also raises concerns of mold growth.
Roof Sags or Droops
A sagging roof with pronounced dips or droops is a serious issue requiring prompt replacement. The sagging occurs because your roof’s sheathing and/or trusses are failing. This structural weakness will rapidly worsen until collapse occurs if the roof is not replaced. Sinking areas or rows of sinking shingles demonstrate your roof can no longer support itself or protect your home.
Damaged Chimney Flashing
The metal components that waterproof a chimney’s roof penetration points are called flashings. They integrate the rigid chimney with the flexible roof surface. Cracks, rust spots, gaps, or separation indicate your flashings have failed. Moisture intrusion through damaged flashings causes extensive leaks. Water will pour into your home until the compromised flashings are replaced.
When to Repair vs. Replace Your Roof
Once you’ve spotted issues with your roof, how do you know whether repairs or full replacement is needed?
Repairs for Minor Age-Related Damage
If your roof shows only minor wear for its age, with no major leaks, damage, or failures, repairs may prolong its lifespan. Replacing a few loose, cracked, or missing shingles prevents additional deterioration related to those deficiencies. Sealing any small gaps, holes or exposed roofing nails also helps maintain waterproofing.
Replacement is Essential for Extensive Damage
If inspections reveal moisture on roof sheathing, signs of water leaks, soft spots in the roof deck, attic moisture staining, more than 10% of shingles that are damaged or missing, large areas of granule loss, active roof leaks, or any signs of structural instability like sagging, your roof requires full replacement. Patch repairs may temporarily ease some leakage, but the underlying deterioration will continue worsening.
Roof Age Matters
Another important roof replacement indicator – the age of your roof. Asphalt shingles last 15-30 years on average. If your roof is nearing or exceeding 20 years yet seems intact upon inspection, its lifespan may be slightly extended through repairs. But once your roof hits 20 years old, replacement provides the only reliable long-term solution, regardless of its outward condition.
What’s Involved: Roof Repair vs Replacement
Roof Repair Scope
- Inspect roof’s condition & determine repair locations
- Remove debris from roof surface
- Replace damaged, loose or missing shingles & secure properly
- Apply sealant to small holes, gaps, & cracks
- Repair or replace any damaged flashings
- Check that ventilation and drainage systems are clear
- Confirm repairs maintain waterproof integrity
Roof Replacement Scope
- Full inspection of roof structure & sheathing
- Tear off all existing roof materials down to the roof decking
- Replace any rotted, split, or moisture damaged deck boards
- Install roofing underlayment & ice/water shield membrane
- Calculate required materials & ensure proper overlapping
- Install new drip edge & flashings around penetrations
- Nail, glue or adhere all new shingles to create waterproof barrier
- Reinstall ventilation components sealed to new roof
- Apply ridge caps & seal shingles at valleys, eaves & rakes
- Safety check & cleanup of site
As this overview demonstrates, roof repairs involve targeted fixes, while replacements essentially re-create your roof’s layers for long-lasting integrity and protection.
