Roof Replacement: Signs You Should Know
Is it time to replace your roof? There are many factors to consider when deciding whether to replace your roof. So how do you know when it’s time to replace your roof? There are three signs that it is time for a roof replacement. First, age spots, which are easily seen from ground level. There are seven age indicators that your roof is past its prime and is in need of replacement. Uneven shingles with cupped edges that can be caught by a windstorm are a sure indicator that your roof needs replacement. Roof shingles that have lost their granules are more prone to the damaging elements of UV rays, which can cause shingles to become brittle and break. Over many years, UV rays can break down shingles, causing them to crack. Discoloration is another sign of an aging roof. UV rays not only break down roofing shingles but also discolor them over time.
When is the right time to replace your roof?
Dark streaks on a roof can at first seem like just an aesthetic issue, but algae and lichen growth can damage shingle granules over time. The presence of moss can also be a determining factor in a roof’s age. Moss holds water, which can add weight to the roof it’s supporting, and breaks down granules faster. Lastly, time is the biggest indicator of the need for roof replacement. Most indicators point to a 30-year lifespan for architectural shingles and a 20-year lifespan for a 3-tab system. The second major factor to consider is storm damage. Hailstorms can cause immediate damage to shingles, flashing, and gutters. Visible signs of hail damage can include cracks, divots, and granule loss on the shingles.
Wind from a storm can also cause irreparable damage to a roof. When shingles are bent or forced up by wind, they can lose their lamination and are more prone to future failures. Shingle loss due to wind can also expose a section of the roof to water and the accumulation of debris. Finally, the presence of water leaks can be a determining factor in whether a roof needs replacement. Many homeowners may put off roof replacement and be unaware of age or storm damage, leading to leaks into the roof deck, insulation, and wallboard.
