Why is My Roof Steaming After Rain on Long Island?
Your roof is likely steaming after rain due to evaporation. It’s a common sight in Nassau and Suffolk Counties, especially in summer when rainstorms can hit hard and clear as quickly as they arrived.
Evaporation from your roof isn’t anything to worry about, but it’s a good reminder to check your attic for active leaks and signs of water entry.
When is a Steaming Roof a Problem?
In most cases, some evaporation from your roof after a sudden burst of rain is nothing to worry about. Dark shingles absorb heat, and short bursts of rainfall during summer aren’t enough to cool the shingles completely. When the rain stops, you will see the water rapidly evaporate from your roof.
- Don’t worry if there are a few minutes of evaporation. This is actually normal, and you’re likely to see it again after noticing it the first time.
- The only time you should worry is if your roof steams for an excessively long time after rainfall (more than 5 to 10 minutes). This could indicate that there’s moisture trapped on the roof, or that the attic is poorly ventilated and excessively hot.
Noticing Steam is the Perfect Reminder to Check Your Attic for Leaks
Most homeowners don’t check for roof leaks until there’s water coming through the ceiling or running down the walls. It’s helpful to check for leaks after sudden downpours, especially if it has been a while since your last roof inspection.
How to check your attic for roof leaks:
- Look for Water Stains and Discoloration: Check the underside of the roof deck or rafters. If you can see brown, yellow, or gray rings, these can indicate that water is leaking slowly and spreading as it travels.
- Note any Dark Spots on Wood: A less obvious sign is dark spots framing or the underside of the roof deck.
- Check for Mold or Mildew: Water entry from a roof leak is a common precursor to mold. Look around for signs of mold or mildew. You might also notice a musty odor in your attic.
- Check That Your Insulation is Dry: Insulation can saturate and degrade when your roof is leaking. If it looks compressed, clumped, or stained, it’s a strong sign that water has been getting through.
- Look for Sunlight Coming Through the Roof Boards: Turn off the light in your attic, or disable your flashlight. Look up toward the roof and check if there’s any sunlight coming through. You should only be able to see light around your vents. If it appears elsewhere, then there’s a way for water to get through.
- Press the Underside of the Roof Deck to Check for Soft Spots: If you can move around in your attic safely, you can press against any dark or discolored spots to check if the deck is soft and sagging.
You’re more likely to identify leaks right after it rains, especially if the leak is slow and hasn’t worked its way into the rest of your home. If you discover signs of a leak, you can book a roof inspection with a licensed roofer in Suffolk or Nassau County.
