Last week we pointed out that the guys over at GAF, who manufacture roofing materials, posted a really good set of photos to help you determine if you have red flags that need to be carefully examined. They call them Key Danger Signals of a Failing Roof?
Let’s look at the other danger signs that likely point to a roof replacement need. But remember that not every type of roof damage means you have to replace your roof. You might be able to patch it and then prepare and plan to have it replaced in the near future.
But be on the lookout for the issues below to help answer the question, “How do I know when to replace my roof?”
Possible cause: Leaking water supply or drain line OR inadequate, faulty shingle underlayment which allows leakage. Mold could also be caused by inadequate ventilation which traps moisture.
Possible cause: Poor attic ventilation. If the exterior of your home looks like this picture you have a real problem. Does this answer the question, “when to replace my roof?” Not yet. But you need to figure out what is causing this problem. You might have a leak which is slowly eating away at your sheathing or siding.
Possible cause: Shingles have reached the end of their useful life OR a major storm tore up the roof. Sometimes your shingles have just reached their end of life and you need to replace the roof. If you have 20 year shingles, have had your roof on for 25 years, and it looks like this photo you can answer the question, “How do I know when to replace my roof?” in by nodding your head repeating after me, “Yes. I need a roof replacement.”
Possible cause: Loss of granules due to age of shingles. This one is tough. Your singles might have simple been worn down over time or you might have mold growing on your roof. It is important to take a closer look. Do not jump to roof replacement mode just because you have a few worn shingles. In this photo, the granules have definitely been worn away. This is a warning sign that a roof replacement is in your future. But does this answer the question “when to replace my roof?” Not exactly but it is a warning sign. At some point these shingles will fail but you still might have a few years if the rest of the roof is in fair shape.
