Cracked house siding is a sure means for water damage to your home if left unrepaired. It is important to replace cracked house siding as soon as it is observed, to prevent water from seeping in behind the house siding and causing mold, mildew, and rot to the sheathing and framing.
The same goes with repairing damaged shingles on the roof. While it may be difficult to notice damaged shingles from the ground (unless you are already experiencing leaks inside your home), you can hire a professional to inspect your roof at least annually.
You should always be on the lookout for damaged siding and shingles. It is important to repair or replace these items as soon as it is observed to prevent water damage.
All in all, preventative maintenance, with all the time and money it consumes, is far more cost effective than waiting until something breaks or is damaged, and having it repaired. Preventative maintenance can avoid repairs, extend the life expectancy of many components, and in some cases, reduce energy consumption. Completing these repairs will protect your investment in your home and not only keep it in great condition, but will keep your home efficient and more valuable when it is time for you to sell.
