When it comes to residential roofing in the state of Oklahoma, it can often be difficult to know when it has passed its breaking point. Sometimes it is hard to gauge the extent of damage from hail, wind, old age, and other problems. Although your roofing contractor is always happy to help evaluate the condition of your roof, there are several indicators you can rely on to know it may be time for an upgrade.
One telltale sign you could benefit from a new roof is when your underlayment starts to sag. The underlayment is the layer of materials directly underneath asphalt shingles. When it is damaged or holding onto water, roof repair is simply inadequate in addressing the problem. This is especially true when mold is involved.
Some leaks are easy to fix, particularly if they are entering your home via just one or two damaged shingles. When water damage is abundant, however, you are likely better off financially to start from scratch. You’ll know this is the case if you seek streaks of water running down your exterior or interior walls.
Where there is water damage, there is likely to be an intruder. Mold loves to collect in dark, damp areas, particularly in the hot and humid summer. Roofing is a natural place for mold colonies to grow. If you can spot it quick enough and it is limited to a small area, this scenario can usually be resolved with repairs alone. If it is extensive or has reached your underlayment, however, your entire roof may be structurally unsalvageable.
When damage is isolated to a single shingle or small patch of them, your contractor may be able to replace the affected area without touching the rest of your roof. If damage to shingles is widespread, however, it often makes more sense to replace the entire roof rather than replace individual materials.
These are just some key indicators you may need a new roof.
