Typically, most homeowners replace their roofs only after roof failure. Waiting until the roof fails to work at it is not a good idea as it may lead to further damages to your house, which will be a lot more costly to repair. There are various signs that you should check whenever you are doing preventive maintenance, which will indicate the time to change the roof. Some of the signs that you need to buy commercial roofs for replacement are highlighted below.
Shingle Tabs Are Cupped, or Edges Are Curled
You should check to ensure that the shingles are in good shape, especially during times of extreme weather conditions. Ensure that all the shingles are lying flat against the roof. If you notice any patches that are damaged, buckling, or cracked, make sure you get experts to do the repairs as soon as possible. If the patches that need repairs are too many, you should consider replacing the entire roof.
Light Can Pass Through the Roof
You have to get your roof repaired, or possibly replace the entire roof if you notice streams of light through your roof. That is an indication that the roof has holes and cracks, which are significant signs of a failing roof. Not doing anything about it may result in you having to deal with water damage during the rainy seasons.
Dark Stains and Streaks
If you notice any dark streaks or dark stains on the underside of your roof, at times even running down the walls, then your roof needs repairs or replacement. The dark stains and streaks are usually as a result of the roof leaking moisture. If left unrepaired, it can result in damage to the interior structure of your home as well.
The structure of your roof can begin to sag because of water issues. To determine if that is the case, you can use a broom or your hand to prod against the sagging spots lightly. You can conclude that it is moisture damage if some spots feel soft and wet when you prod them.
In various cases, the roof may be too old and will need replacement even if it does not show any apparent signs of failure. Most roofs are designed to last about 20 to 25 years. If your roof has served you for a longer time than that, you should make plans to replace it soon.
