Such costs make it no wonder that many homeowners fear the dreaded diagnosis that their home needs a new roof. While there’s little homeowners can do to reduce the cost of a roof replacement, there are warning signs homeowners can look for that might indicate a roof replacement is on the horizon.
The presence of algae
If the roof has lots of dark streaks and stains clinging to it, that is likely algae, which can grow on the roof for quite awhile. Algae does not necessarily do any damage to a roof, but it does do some damage to a home’s physical appearance, as algae on the roof is not very pleasing to the eye.
Like algae, buckling shingles are another unsightly problem on a roof. But buckling shingles are more than just an eyesore, they actually might indicate significant problems. When shingles buckle, that’s typically because hot air from the attic is forcing the shingles away from the home. Buckling shingles also indicate that the roof is poorly ventilated.
Unlike the warning signs already discussed, mold is not visible on the outside of the home. Instead, homeowners should look in the attic of a home to see if there is any mold growth. If there is, the roof is likely leaking, and the health risks of mold growth in a home are substantial. Mold is not necessarily easy to detect, so a professional inspection might be in order if mold growth is suspected.
Perhaps the most discouraging sign a homeowner can see on his or her roof is roof rot. Roof rot appears when a roof is in considerable decay and, if not addressed, its consequences can stretch far beyond the roof, damaging other parts of the home thanks in large part to water getting through the roof.
Homeowners might fear a full roof replacement because of the cost associated with such a project. But if ignored, problems with a roof could eventually prove far more costly than the price of replacing the roof.
