How do you know if your roof might need replacement or repair? Take a walk around your house and actually look at it! While roof damage is not always obvious, in many cases you will be able to tell if something is wrong. A damaged roof can cause issues both outside and inside your home and so it’s important to catch problems early, before they cause more extensive damage.
So…what do you look for?
Shingles are a big part of your roofing system. A compromised shingle can allow water to seep underneath, into the underlayment, roof deck, and into your home.
- Curled shingles: These are easy to spot. Individual shingles lift and curl at the edges. This is often a failure of the tar strip or a sign of aging.
- Cracked shingles: Cracks may appear to be just on the surface, but most often that is not the case.
- Blistering shingles: Small “bubbles” or “blisters” appear on the shingle. This can be due to excessive heat, which causes expansion in the shingle and erosion.
- Cupping shingles: The center of the shingle will be “sunken”, almost creating a wavy look. Age and heat are often the culprits.
- Missing shingles: These will be very obvious. This is most often due to weather or age.
- Flaking shingles: The top of each shingle is made up of tiny granules, which protect your shingles and add a layer of UV protection. When the granules begin to flake you may find some in the gutter, or see bare or dark spots on the roof. This is most often caused by age. Flaking leaves the shingles vulnerable to heat, and to cracking, blistering, etc.
Flashing is the metal/tar/roof cement/etc that connects and seals the seams between the roof and the chimney, vents, skylights, or any other protuberances on your roof. It prevents leaks. If your flashing is cracked, missing, or displays damage, it can cause real leakage problems.
Fascia is the wood directly underneath the last layer of shingles—typically your gutters will hang on your fascia. If fascia is rotten, it could mean that your roof is leaking, or that there is something wrong with your gutters.
Do you see water spots on your ceiling or interior walls? Are there excessive water marks on a particular section of your exterior wall—or even peeling paint? Most often, this is a result of a roof leak, or damaged/rotten fascia.
While mold, mildew, moss, algae, and other growths on your roof may not cause damage in and of themselves, what they do allow is for water to collect underneath with no opportunity to dry out. While roofs are made to withstand water, they are not built to have water sitting on them for long periods of time. This water can lead to rot.
If you see sagging in your roof, this is definitely cause for concern. Most likely, the roof decking (the bottom layer of your roof) has been compromised. If water is leaking into your roof deck, it will not be long before it leaks into your home.
