As soon as you’re done performing your roof’s interior, the next thing that you need to take into account would be its exterior. Interior roof checks play a significant role in any roof-building or repairing project since it helps you initially see the damage, and determine which among those causes could have reached inside your roofing structure.
Exterior roof checks, on the other hand, can save you money and even time because it allows you to see the damage from the exteriors before it even reaches the interior. You can check your roof’s exterior by going to the attic, and these are some of the things that you need to watch out for to determine if you need a new roof:
Leaks and other water damage can be potentially seen as they are obvious. They usually have dark stains, spots are sagging or some of the tiles may have already started to rot. These are signs that your roof is damaged and needs to be addressed immediately to prevent it from getting worse.
Dark Streaks / Staining
Just how you checked your roof’s interior, you may also want to look for dark streaks and stains that are visibly noticeable, which again, could indicate there’s water damage. If you’re suspecting it’s damaged, then it probably is.
Wooden and asphalt roofs are prone to rotting, so you may want to be on the lookout for roofs that may have been decayed. Some signs would include but are not limited to missing tiles, a buildup of molds, and rotten tiles.
Algae And Moss
Luckily, the growth and buildup of algae and moss don’t necessarily mean that your roof needs repairing or replacing. Instead, both of these looks unpleasant to the eyes and are common in areas where the weather conditions are usually humid. You may still want to get rid of them though.
Presence Of Shingle Granules
Another easy way to see if your roof needs repairing or replacing would be the presence of shingle granules in your gutter. If you’ve seen these shingles in your gutter, then there’s a great possibility that your roof has water damage or possibly decay has started to form.
Look for those areas where shingles are missing, cracking, buckling, or curling. Rotting is common to shingle roofs as well so you may want to watch out for these signs.

If your chimney is damaged, or you’ve potentially found flashing around your chimney’s base, you may need to have it carefully checked as these areas are prone to water damage and can be one of the major culprits. You may want to consider replacing it with a metal flashing system.
Consider checking the area of your roof where two parts of your roof sloped down to meet. Since there’s a gap in between these two slopes, this area is susceptible to water buildup, hence, water damage.
Roof Is More Than 20 Years Old
One surefire way to determine whether your roof needs replacement is when it has been there for more than 20 years. If you’ve grown up in that house, then it’s possible to determine the age of your roof. If not, you may want to consider keeping an eye out to your neighbors if they’ve had a recent roof replacement, or if they’re about to get one.
