Roofs that undergo maintenance usually reach their lifespans without a lot of problems or failure. It may just appear worn out, in which case you still need to replace it. Leaving an old roof in place, even if it does not exhibit problems, can result in many issues that end up being too costly to repair.
You can watch out for possible signs of trouble to avoid having to deal with major issues. Alternatively, you can contact one of the reputable roofing Burlington companies to inspect it and help you re-roof successfully.
Signs you should not ignore
Old age
A roof that has reached 20 years will no longer be as effective in protecting the home as a new roof. Although many roofing shingles are made to last longer than that, constant exposure to natural elements and other factors such as poor ventilation can speed up their ageing process. Any roof, regardless of the material used, that is nearing or has passed that period should, therefore, be replaced.
Presence of dark streaks
Dark streaks mostly appear on the roof deck and are caused by algae in the air. They are not dangerous to the roofing material or structure, but they reduce the visual appeal of the roof. You may want to replace the specific location they appear on after inspecting the whole roof.
Growth of moss
Roofs that are hidden from direct sunlight tend to have moss growing on them, especially during the rainy season. While such cases are mostly cosmetic, they can lead to more serious damages.
Moss will retain moisture on the roof surface, and when it freezes in winter, the granules on the shingles will be destroyed. Even if the moss is removed, it will grow again if the roof is still shaded.
Cleaning is still a good option, but removing trees and other elements that could be blocking the sun may be better. Look for a roofing professional with experience in dealing with moss problems to give you a long-lasting solution.
Damaged shingles
Experts often recommend that you inspect the roof regularly or at least twice a year to confirm that shingles are still intact. If you notice some cracking or loosening in some areas, even if it is not extreme, you should consider replacing them.
Shingles with curled edges should also be replaced.
Rugged appearance
Sometimes the roof may not have specific issues but will look worn out even if it has not been in place for 20 years.
New roofs in the neighbourhood
If your roof is still in good condition, but the neighbours are changing theirs, consider having a new one too. Homes built at the same time in the same location and exposed to the same weather conditions will wear down at the same time, which means you will be forced to change yours too.
Roofs that have bald spots on shingles also need thorough inspection and possible replacement. Other signs to look out for include frequent leaks and damages that are making repairs more costly than a replacement.
