Have you ever looked at how much it would cost to replace your roof? Depending on the size of your home, it could cost many times what your car cost. I’m sure that seeing that number would motivate you to take better care of the roof that you have. Just like you take good care of your car and maintain it, you should do the same with your roof.
The one main thing that does the most damage to your roof is water. Water can get in underneath the roof and cause all kinds of damage, so it is important that you protect it.
Your gutters and downspouts are meant to funnel the water off of the roof, but sometimes these can get clogged and lead to water backing up underneath the roof. Keep them clean, especially when there is a storm approaching, and clear the roof of leaves and debris as often as it is needed.
