It can be very frustrating when a roof you purchased 20 years ago and you were told the shingles have a 30 year (or sometimes a 50 year) lifespan are now failing. You quickly find yourself getting estimates on replacing your roof. Why is that?

Asphalt shingles expand and contract with weather changes. Midwest winter can be one of the hardest times on a roof because the ice, snow, wind, and drastically low temperatures wreak havoc on your shingles. The shingle adhesive bond is strained as it cannot keep up with temperature changes even if its going from 15 degrees to 35 degrees, especially hard on older roofs. As the snow/ice melt and the wind picks up, and shingles barely holding on will easily blow off your roof. If your roof hides the bald shingle spots from your view, you will still know you’ve lost shingles by finding them in your yard.

Over time your asphalt shingles will dry out and become brittle. Expansion and contraction accelerates the drying rate. After a winter full of temperature changes, your frail shingles may be crumbling; other signs can be curled shingles, cracked shingles, or missing asphalt granules.

Even if your roof-life is evaluated in having 3-5 years left, it won’t mean those remaining years are without maintenance costs. It’s up tot he homeowner to determine if the maintenance costs are worth it. Example: If it costs $10,000 to replace your roof today; however, you could wait 3 years with repairs costing $2,000. Depending on your point of view, repair costs could be 20% towards the roof replacement.
