An asphalt roof that uses asphalt roll roofing and asphalt shingles has a typical life span of up to 25 years. After that time, the asphalt roll roofing will begin to deteriorate. The effects of direct sunlight, moisture from rain and snow and the change in temperature has a negative effect on the asphalt. It will begin to crack and tear even at the slightest touch. In areas where the shingles are gone and the roll roofing is exposed, water can get under the roll roofing and begin to deteriorate the wood underneath. Over time, branches falling on your roof will also start to poke holes in your older asphalt roll roofing.
