Why to inspect your roof
Fixing minor roof problems before they become costly is a very good way to prevent more severe damage to your roof and reduce home maintenance costs.
You also need to be aware of the aging and weathering of your roof - know when is time to replace it.
When to inspect your roof
Most experts agree that is a good idea to check regularly your roof at least twice of year, ideally in spring and fall.
Check your roof in fall to prepare for the winter - it is going to be more difficult to fix the roof in bad weather when is cold or you have ice and snow on your roof.
Check your roof in the spring to find if the winter damaged your roof.
Another good time to do a roof inspection is after a severe storm.
What to look for at the roof inspection.
Broken or missing shingles
Shingles that are blistering, cracking or buckling
Patches of moss and lichen
Loose, cracked or rusted gutters
Look for signs of leaking - they might tell you that the roof is broken without you noticing it.
Investigate if the ventilation in your roof is working - check if you have mold mildew and wood rot
