Hi Guys, I’m a HVAC contractor and definitely do not deal with roofs on a day to day other than walking on them. I noticed a water stain in my kitchen ceiling this week about the size of a softball, not wet to the touch.
Looked in the attic and saw signs of water on a rafter and sheating directly above the stain about halfway up the roof. Dark and White staining at the top of the rafter sides. Looked at my roof and all looks good from a novice perspective. What I did notice is right where the rafter water marks start in the attic is where my gutter from my hip roof drains unto my gable roof (split level house). So am I crazy to think that with heavy rain the water is coming out of this gutter and getting under the shingles? All my vent boots look good. 30 years arch shingles 9 year old roof with new sheating installed as needed (No shingles under the new shingles).
