Signs of Roofing Damage

“Obvious” Signs of Roof Damage

While walking through a mall the other day I noticed a vendor, you know, the ones who set up shop in the middle of the walkways in the mall. He was selling shoe products and he rarely lifted his head because he was interested in the people’s shoes that were passing by to see if they needed his services. So he kept his head down.

I couldn’t help but chuckle watching him, because I do the opposite. I look up. Being in the roofing industry I find myself looking up most of the time at the roofs on houses when I’m out driving around. Question is… how much are we missing when we aren’t seeing the big picture? And are we overlooking the obvious?

Thunderstorms and Roof Damage

I often have homeowners, after a thunderstorm with hail has passed through their area say, “I looked up at the roof and I don’t have any damage.” Unfortunately, wind and hail damage can be easily overlooked without close examination. Just looking up at the roof from the ground most likely won’t reveal the hail damage that may have occurred during the storm. You have to get on the roof for a close inspection or you could miss the obvious.

Roofing Shingle Damage

There are obvious tell-tell-signs to look for when you inspect your roof. “Shingle damage.” Storms will often blow limbs off of trees and they fall on to the roof. Falling limbs from trees can tear or gouge shingles or even puncture a whole in the roof. Debris should always be removed from the roof and well inspected for damage.

Look for “hail dents and bruises.” When hail hits the shingles on your roof it leaves a distinctive mark. The velocity of the hailstone when it hits will knock the granules off the fiberglass mat of the shingle leaving a bruise and sometimes even a break in the mat. It will have the appearance of a bruise. If you have a metal roof the hailstone will leave a dent or ding.

Wind Damage to Roof Shingles

Another obvious sign to look for is shingles that have been “twisted or blown off.” All shingles should have a manufacturers’ warranty rating of over 60 mph. for 20 to 25 year shingles and 130 mph for 30 year to lifetime shingles. Twisted shingles, or shingles that have blown off, leave the roof exposed to possible water damage. These shingles should be replaced as soon as possible to avert expensive repair.

What may not look obvious to a homeowner may look very obvious to an experienced roof contractor or roof salesman. It’s never a bad idea to call a professional roofing expert for an inspection. Most roofing companies offer free inspections and would be glad to give you a free estimate for a roof replacement or repairs. If you’re in East Texas, you can call the guys at

Here’s something to keep in mind…

After a storm don’t just look up at your roof from the ground, because, “Sometimes the most difficult thing is to be able to see the most obvious thing.”
