Tile roofs are renowned for their durability, aesthetic appeal, and ability to withstand harsh weather conditions. When properly installed and maintained, a quality tile roof can last 35 years or more, often outlasting the structure beneath it. However, like any roofing system, tile roofs face unique challenges that can compromise their performance and longevity.
Understanding these problems can help you identify issues early, make informed maintenance decisions, and protect your investment. Let’s explore the most frequent tile roof problems homeowners encounter and what you can do about them.
1. Cracked, Broken, or Missing Tiles
Individual tiles can crack, break, or go missing due to various factors, including severe weather, falling debris, foot traffic, or simply age-related wear. Even a single damaged tile can expose the underlying roof structure to moisture and lead to more serious problems.
What Causes Tile Roofs to Break
- Hail damage during storms
- Falling tree branches or debris
- Thermal expansion and contraction
- Poor installation or low-quality tiles
- Walking on the roof without proper care
How to Tell if your Tile Roof has Cracks
- Visible cracks or breaks in tiles
- Missing tiles
- Tile fragments in gutters or around the house
- Water stains on interior ceilings
How to fix a Cracked Tile Roof
Individual damaged tiles should be replaced promptly by a licensed roofing professional. While this might seem straightforward, proper tile replacement requires matching the existing tiles and ensuring correct installation to maintain the roof’s integrity and appearance.
2. Tile Slippage and Shifting
Tiles can gradually slip out of position or shift from their original placement, creating gaps that allow water infiltration and compromise the roof’s protective barrier.
What Causes Tile Roof Slippage
- Inadequate fastening during installation
- Deteriorating underlayment or adhesive
- Extreme temperature fluctuations
- High winds or storm damage
- Natural settling of the building
Tile Roof Slippage Warning Signs
- Uneven tile lines or patterns
- Gaps between tiles
- Tiles hanging over roof edges
- Visible underlayment through gaps
How to Fix Tile Roof Slippage
Slipping tiles need to be repositioned and properly secured by a certified roofing contractor. This often requires removing multiple tiles to access and repair the underlying fastening system or underlayment.
3. Underlayment Deterioration
The underlayment beneath tiles serves as a crucial secondary barrier against water infiltration. When it deteriorates, the entire roof system becomes vulnerable to leaks and moisture damage.
What Causes Underlayment Deterioration
- Age-related degradation
- Exposure to moisture through damaged tiles
- Poor ventilation causing condensation
- UV exposure through gaps in tiles
- Inadequate initial installation
Warning Signs of Underlayment Deterioration
- Water leaks during rain
- Visible deterioration of underlayment material
- Sagging or soft spots in the roof deck
- Musty odors in the attic
How to Fix Underlayment Deterioration
Underlayment replacement typically requires removing tiles in the affected area, installing new underlayment, and properly reinstalling the tiles. This is a job for roofing professionals.
4. Inadequate Fastening Systems
Tiles that aren’t properly fastened can become loose, shift position, or blow off during storms, creating immediate safety hazards and exposing the roof to water damage.
What Causes it
- Incorrect fastener type or size
- Insufficient number of fasteners
- Improper fastener placement
- Corrosion of metal fasteners
- Failure to follow the manufacturer’s specifications
How to Tell if Your Tile Roof isn’t Properly Fastened
- Loose or rattling tiles
- Tiles that move when touched
- Missing fasteners visible from below
- Tiles blown off during storms
How to Fix Inadequate Fastening on a Tile Roof
Proper fastening requires using the correct type, size, and number of fasteners as specified by building codes and manufacturer guidelines. Professional installation ensures compliance with local requirements.
5. Flashing Failures
Flashing around chimneys, vents, skylights, and other roof penetrations can fail, allowing water to enter the roof system and cause significant damage.
What Causes Flashing Failures on Tile Roofs?
- Improper initial installation
- Corrosion of metal flashing
- Separation due to thermal movement
- Damage from severe weather
- Age-related deterioration
Warning Signs of Flashing Failures
- Rust stains on flashing
- Gaps or separations in flashing
- Water stains around penetrations
- Loose or missing flashing components
How to Fix Flashing Failures on a Tile Roof System
Flashing repairs require expertise to ensure proper waterproofing. This often involves removing surrounding tiles, replacing or repairing the flashing, and properly sealing all connections. We recommend you contact a licensed roofing professional to perform this fix.
6. Moss and Algae Growth
Moisture retention and organic debris can lead to moss and algae growth on tile roofs, which can damage tiles and create an unsightly appearance.
Causes of Moss and Algae Growth on Tile Roofs
- Excessive moisture and humidity
- Poor drainage or ventilation
- Organic debris accumulation
- Shade from trees or structures
Moss and Algae Growth Warning Signs
- Green or black discoloration on tiles
- Visible moss or algae growth
How to Get Rid of Moss and Algae on Tile Roofs
Professional cleaning and treatment can remove moss and algae. Long-term prevention involves improving drainage, increasing ventilation, and regular maintenance.
Tile Roofing Maintenance Tips
Here are essential maintenance tips to keep your tile roof in excellent condition and maximize its lifespan:
Regular Inspections
Schedule professional roof inspections at least once a year. Look for obvious problems like missing tiles, visible damage, or signs of water infiltration. Regular inspections will allow you to deal with simple, affordable problems before they become larger, more expensive issues.
Prompt Repairs
Address problems immediately when they’re discovered. Small issues can quickly become major problems if left unattended.
Proper Ventilation
Ensure adequate attic ventilation to prevent moisture buildup and reduce thermal stress on the roof system.
Professional Installation
Tile roofs are generally more challenging to build and assemble compared to other roofing materials like asphalt shingles or metal roofing. That’s why it’s extra important to find a qualified roofing contractor who has experience with tile roofing systems. Always use qualified, experienced roofing contractors who understand tile roof systems and local building codes.
Conclusion
Tile roofs offer excellent durability and weather resistance when properly installed and maintained. Understanding these common problems helps you protect your investment and ensure your roof continues to provide reliable protection for decades to come.
Regular maintenance, prompt repairs, and professional installation are key to maximizing your tile roof’s lifespan and performance. Don’t hesitate to consult with roofing professionals when problems arise – early intervention is always more cost-effective than waiting for minor issues to become major repairs.
Remember, a well-maintained tile roof is not just a protective barrier for your home; it’s a long-term investment in your property’s value and your family’s safety and comfort.
