There are quite a few home improvement projects we tend to overlook until we are presented with a challenge. A roof repair or replacement may be at the top of that overlooked list as we are reminded of the old adage, "out of sight, out of mind." We may also neglect certain large-scale projects because of their longevity, thinking our roof will last forever. In either instance, "an ounce of prevention is worth a pound of cure." Stopping minor problems in their tracks may add some years to your roof. Here are some things to look for before determining if shingles replacement or a new roof is in your future.
Start looking inside for roofing clues. Walk around the interior of your home, room by room. Do you see leaks or water stains on the ceiling? Assess the shingles from outside. Use binoculars for a better view. Do you see dry rot or fungus? Are there missing shingles or broken tiles? Discolored or curling shingles or shakes may indicate potential problems. Soffits, flashings, and down spout exits should be examined. Can you remember when the roof was last replaced? Roofs do not age well like fine wines or cheeses. If your roof is over 20 years old, have it inspected by a professional.
You may observe a blue-green algae spread by airborne spores. Algae growth on shingles is not uncommon in hot and humid areas. While not detrimental to the integrity of the roof, black algae streaks may appear unsightly. Installation of algae resistant shingles may be an option. Placement of copper or zinc treated metal sheet strips can prevent algae from returning. Contact a professional roofing company for a consultation and further options.
