Five Signs Your Roof Needs To Be Replaced

Posted on

Roof replacement is one of those things that nobody wants to have done, but it is vitally important to maintaining your home. While most issues can be taken care of with simple repair jobs, you may also need to have your home checked out by residential roofers for a full replacement. Since most roofs have an average life expectancy of 15-30 years, how do you know if it's time?

Age of Roof

As stated above, the average life of a roof is less than 30 years if you're using asphalt shingles. If you have metal or slate, you can expect twice that amount of usage, if not more. If you've built a new home, this should be a hard deadline on your calendar to replace it, but if you bought used, make sure you ask the previous owner or real estate agent about when the roof was installed.

Shingle Granules

Over time, your shingles will start to deteriorate and pieces of it will fall into the gutter. Check your gutters frequently to see if you have little black specks inside; if so, it might be time to have it inspected by residential roofers. They may replace just a few shingles, or encourage you to have the whole thing replaced.

Warped Shingles

In some cases, you may be able to tell from the ground if your roof needs to be replaced. If you notice shingles that are curling upon themselves, or the chimney is starting to separate from the rest of the roofline so that the flashing is damaged, it's probably time to get the roof replaced.

Sagging Areas

Your roof is under extreme stress nearly all the time, from UV rays to rain and hail and snow. One of the first signs that there is an issue is sagging in a certain area, which will only get worse the longer you leave it. Water can pool inside those sagging areas and cause the shingles to deteriorate faster and faster until the weight of the water crashes through. This is one time you'll want to get your roof replaced as soon as possible.

Energy Bills

Most roofs these days are energy efficient, which means they should do a great job of trapping in heat in the winter and cold air in the summer. If your energy bills have gone up, and you've crossed off the usual suspects - insulation, garage door, old A/C, etc - you might check your roof to see if it's still sound.
