Other Health Conditions. On rare occasions, being tired after a meal or simply sleepy all the time could be a sign of another health problem. Diabetes, anemia, underactive thyroid, celiac disease, food intolerance, and sleep apnea can make post-meal drowsiness worse.
Having a roofing contractor remove (and dispose of) old roofing materials, then install asphalt shingles runs about $1-$4 a square foot, or a total of $1,700-$8,400 for a typical ranch-style home (1,700-2,100 square foot, gently sloping roof).
It's a pretty unnerving scenario. First, your roof starts to leak. So you call some local roofing companies to get some cost estimates on repair work. They all say you're going to need a complete replacement, because the shingles are beyond repair. One company says it's going to cost $9,000 to replace the roof completely.
