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).
Understand that if your roof has only one layer of roofing on it, then the replacement cost will be lower per square than one with two or several layers of roofing. Typically for each additional layer, you can expect to pay an additional $25 per square for removal.iza, the cost to upgrade to a stain-guard roof is in the range of $5.00 to $10.00 per square. So having said that, letâs say your roof is a 30 square roof, 30 X $10.00 = a $300 up charge to not have your roofing shingles show up with those dark and unwanted streaks after a few years.
