6 Signs of Poor Roof Ventilation
Your roof protects your home from the elements. If a roof is poorly ventilated, all sorts of structural problems may ensue. Roofing ventilation refers to the intake and exhaust vent system and the free flow of air in the attic. Some signs of poor roof ventilation are obvious, such as leaks or pests in the attic. Any sign of moisture damage is another red alert.
When it comes to residential roof repair, depend on the experts at North Carolina’s Premiere Roofing and Gutters. Here are signs that your roof may have ventilation issues:
Look at your shingles straight on. They should form straight lines. If the shingles are wavy, that’s a sign of water damage beneath.
2. Granule Loss
Granules on asphalt shingles protect them from the elements and damaging ultraviolet light. A certain amount of granule loss on asphalt shingles is normal. However, too much granule loss results in leaks.
3. Sun Blistering
It gets hot in North Carolina in the summer. When the sun bakes your roof and it gets really hot, that can cause blisters in the shingles. Look for asphalt peeking through the shingles. What looks like hail damage can actually be poor ventilation. Any sort of cracking or buckling can indicate that the surface temperature of the roof is too high.
4. Ice Dam Formation
If you notice ice dams forming on the roof in winter, that’s a sign of poor roof ventilation. The buildup forms due to a too warm attic. Water from ice dams can seep into the shingles, causing water damage to the decking.
Condensation can form on the back side of shingles. It occurs when warm and cold air mix on the back side of the roof and will cause raining on the inside of the roof. Condensation also leads to mold formation, as do leaks.
Proper ventilation prevents condensation and mold or mildew formation. A properly ventilated attic remains dry at all times. Any evidence of moisture in the attic is a sign of inadequate ventilation. If you spot any discoloration in the attic, have it inspected. This way, you can often nip the issue in the bud before it gets worse.
When condensation gets on the back of the decking, it causes the decking to warp. Look for a hump in the shingles. It is worse when there is heat because the sun draws the nails out, causing them to come loose and warp. Always have the roof inspected if you notice a significant number of loose shingles.
