Roof Flashing: The Unsung Hero Of
Residential Roofing Maintenance

Protecting Your Greater Houston Area
Home From The Elements

As residential roofing contractors in the Greater Houston area, we’re no strangers to extreme weather. From scorching summers and high humidity to torrential downpours and hurricanes, our roofs take a beating.

While strong shingles are vital for a good defense, the unsung hero, roof flashing, plays a critical role in keeping your home dry and protected.

Regular roof flashing maintenance in Houston isn’t just recommended – it’s essential.


What Is Flashing In Residential Roofing?

Roof flashing is a thin layer of waterproof material, typically galvanized metal, installed at various intersections on your roof. Think of it as transitional waterproofing for your roof.

Flashing creates watertight barriers around chimneys, vents, skylights, eaves, valleys (where two sloping sections meet), and around walls where the roof meets the siding.

Properly installed and maintained flashing prevents water from seeping into the underlying roof deck, walls, and, ultimately, your home’s interior.


Why Is Residential Roof Flashing Maintenance
Important In The Greater Houston Area?

Houston’s climate presents unique challenges to roof flashing. The constant barrage of sun and heat can cause flashing to become brittle, warp, and crack over time.

Heavy rain and storms can stress the seals around the flashing, allowing water to seep in. Here’s a closer look at why regular maintenance is crucial.

Heat And Sun Damage

Houston’s relentless sun can wreak havoc on roof flashing. Metal flashing can become brittle and crack, or the sealant around it can wear out. These cracks and warps compromise the watertight seal – creating openings for water to intrude.

Heavy Rain And Storms

The Greater Houston area is known for its intense downpours and frequent storms. High volumes of water can overwhelm clogged gutters. This can cause water to back up under the flashing and seep into the roof.

Windblown rain can also exploit weaknesses in the flashing seal, which can create leaks.

Freeze-Thaw Cycles

While less frequent than heat, occasional freezing temperatures in Houston can also damage flashing. Water trapped under or around the flashing can freeze and expand – causing cracks and breaks in the seal.


What Happens If I Neglect Residential Roofing Maintenance?

Ignoring residential roofing maintenance, particularly flashing maintenance, in Houston can lead to a cascade of problems:

  • Leaks: The most immediate consequence of compromised flashing is leaks. Water can seep into your attic, causing mold growth, rot, and structural damage. Interior walls and ceilings may become stained and require repairs.
  • Mold And Mildew: Moisture trapped due to failing flashing creates a perfect breeding ground for mold and mildew. These can trigger allergies, respiratory problems, and even property damage.
  • Reduced Home Value: A roof with neglected flashing can significantly reduce your home’s value. Potential buyers will factor in the cost of repairs when making an offer.
  • Increased Energy Costs: A leaky roof or compromised insulation due to moisture can lead to higher energy bills as your HVAC system struggles to maintain comfortable temperatures.

Don’t wait for disaster to strike! Regular roof flashing maintenance not only gives you peace of mind, it also saves you money in the long run.


How Often Should I Have My Roof Flashing Inspected?

Ideally, you should have your roof flashing inspected by licensed contractors, like Houston Roofing & Construction, at least once a year. More frequent inspections are recommended after major storms or periods of heavy rain.

Here are some additional tips:

  • Clean Your Gutters Regularly: Clogged gutters can cause water to back up under the flashing. Clean your gutters at least twice a year and more often if you have overhanging trees.
  • Trim Overhanging Branches: Tree branches scraping against your roof can damage flashing. Trim overhanging branches to prevent this.
  • Look For Warning Signs: Keep an eye out for signs of failing flashing, such as curling or cracked metal, loose or missing fasteners, and visible gaps around the seals.

By taking proactive steps to maintain your roof flashing, you’ll ensure your home stays protected from the elements and avoid costly residential roofing repairs down the road.
