| Gearhead- Yes, asphalt shingles. They are a Tan/beige color on the light side thats why the tar runs stand out. I've noticed alot of the house's in my neigborhood have the same problem. I'm gonna go out on a limb and say I have 15 yr shingles, probably your normal contractor grade cheapo's. I bought the house when it was about 7 yrs old. I have been told improper ventilation can cause this (a home inspector told me) I do have a ridge vent and attic vents on both ends of the house but no attic fan. I also have vents located in the House eaves. I wouldn't know who to get a hold of concerning the warranty on them unless you are talking about Home owners Insurance? I wonder if that a possibility?
