At the start of warm weather, you may wonder if your shingled roof has withstood the harsh winter weather and is ready for the spring rains. If so, use the guide below to identify problems with your shingles that could be signs that they need to be repaired or replaced.

Ends of Some Shingles Are Turned Up

Over time, moisture and exposure to the sun can make your shingles start to curl up at the ends. When this happens, the continuity of your roof is broken, allowing water to seep underneath the shingles, eventually rotting the plywood and causing your roof to leak.

While standing on the ground or a ladder, look at your roof while your eyes are parallel to the surface. If you see any shingle ends sticking up, this means could mean they have started to curl. However, this could also be caused by missing nails.

If you feel comfortable getting on your roof, check the shingles to see if the ends still have nails in them. If not, place one in each corner on the side of the shingle that has them missing. However, if the material has started to crumble, do not attempt nailing the shingles down, as this could make them deteriorate further. Instead, you may need to have a roofer look at them.

Sections of Plywood Are Visible

While examining the roof, also look for sections where you can see plywood. This means that some of the shingles have blown off. If this has happened, there is nothing to protect the wood from moisture and sunlight, which can increase the rate at which the wood can crack and rot. If the plywood is not covered, this could cause your roof to leak.

Look on the ground to see if you can find the missing shingles. If so, examine them to make sure they are not broken, cracked, or deteriorating. If they are still intact, you can nail them back into place as a temporary patch.

If you are unable to find the missing shingles or they are severely damaged, secure a tarp over the exposed plywood. Then, call a roofer to have them come inspect the problem.

Shingles Have Become Smooth and Shiny 

Another thing to look at when inspecting your roof's shingles is the surface texture. When shingles are in good shape, they have a gritty surface. This helps keep water from settling on the tops and makes it run off of your roof toward your gutters.

Over time, however, this grit can break off, making the surface become smooth and shiny because the base material has become exposed. When this happens, the water can start to settle in any crevices on the shingles, channeling the water beneath them and causing the roof to rot.

If you sporadically find a shingle or two on your roof that have started to wear down, you could try replacing them one at a time by yourself. To find shingles that are sold separately, you can ask the customer service representative at a nearby hardware store or home improvement center. Just make sure to explicitly ask for individual shingles and not rolls, since these are for larger roofing projects.

While you are trying to replace the single shingles, look at the wood underneath them. If it has become rotten, do not attempt to repair the shingles. Instead, cover them with a tarp and contact a professional.

If your shingles are exhibiting one or more of the signs above, your roof could start leaking once heavy rains hit. If large sections are damaged, you may need to contact a roofing contractor to inspect your roof and discuss what needs to be done.
