1. Granules in the Gutter
Asphalt shingles shed granules as they age. A few in the gutter after installation are normal. A steady accumulation — especially after a storm — means the shingles are losing their protective coating and UV breakdown is accelerating.
2. Daylight Through the Attic
If you can see light through the roof boards from inside the attic, water can follow the same path. This usually indicates missing or cracked shingles, failed flashing, or deteriorated underlayment.
3. Sagging Roof Lines
A roof deck that dips between trusses usually means moisture damage to the plywood. In Montgomery County's humidity, even a small leak can weaken decking within a season if it goes unnoticed.
4. Stained Ceilings or Walls
Water stains inside the house do not always appear directly below the leak. Water travels along rafters and can surface feet away from the actual entry point. If you see a new stain after rain, the roof is the first suspect.
5. Shingles That Are Curling or Lifting
Heat and moisture cause shingles to curl at the edges over time. Once a shingle lifts, wind can catch it, and the area underneath is exposed. In the Greater Houston climate, this process accelerates on south-facing slopes.
What to Do Next
If you spot any of these signs, a free estimate will tell you whether you need a repair, a replacement, or just routine maintenance. Most issues are less expensive to address early than after they cause interior damage.
