Moving away from asphalt shingles, you may find a metal option to be more appealing. Metal roofs are durable and can last a long time.

Yes, you can stay home during a roof replacement. I have personally been at home for two roof replacements and take it from me, it was a very loud experience. If you need peace and quiet you may want to vacate the premises while the work is going on. You also want to avoid standing under the soffits or gutter line while the roofers are working.

What if it rains while roofing?

Roofing in the rain is an unsafe practice. Roofers should postpone work until the roof is dry enough to work on without slipping or sliding off of the roof. It’s critical to watch the forecast. Laying tarp on bare roof decking is a common when the roofers have time to prepare. If your bare decking does get wet it may be best to allow it to dry before completing the job.

Why You Should Replace Your Roof?

From a distance, you might not be able to see anything noticeable with your roof worth taking note of. This is why you want to get up close and personal to do a thorough inspection to help you get an understanding of what is happening with your roof. 

With a detailed inspection, you will be able to notice some of the following signs that you need a roof replacement.

1. Your Roof Is Sagging 

If you are seeing signs that your roof is sagging in some areas, this is not a good thing. When a roof is sagging, it means that there are almost certainly areas that have been exposed to long-term water damages. Alternatively, if you live in a colder climate, constant exposure to snow and ice could most certainly cause your roof to begin sagging. 

To spot signs of sagging on your roof, get a good look at the line of the roof. This line should be straight without any curves, sags, or dips. If you do find any of these, you will want to reach out to your local roofing company immediately to schedule an appointment.

2. Your Roof Is Missing or Damaged Shingles 

Another clear sign that you might need a roof replacement is if the shingles that you currently have installed are either missing or broken somehow. 

If this is the case for you, your home has probably been exposed to heavy winds, snow, or rain. These kinds of elements leave your roof with leaks and unwanted damages that will need to be addressed promptly. 

Take a good look at your roof to see if this is happening for you, and take the proper steps towards ensuring a replacement or repair

3. Your Roof Has Buckling or Curling Shingles

When you have a roof that has buckling or curling shingles, it typically means that it is time for a new roof. The reason for this is because intense heat, moisture, and aging have taken its toll on the shingles, which causes them to warp or become unstable. 

Another reason your shingles could be curled or buckling is because they were previously installed incorrectly. If this happens, it leaves them even more exposed to ice damage and wind, causing them to break off or crack. 

You most certainly want to look into either a replacement or repairs if you notice any of this happening to your roof. 

4. Your Roof Has Shingle Granules 

Shingle granules are the tiny specs of rock and crushed up minerals that are embedded in the surface of a single shingle. As time goes on and roofs get older and older, a roof can start to get bare spots that cause these granules to become loosened and run into your gutters.

When looking for these granules, remember that they look like sand crystals and are darker because of the shade of the shingle. When these granules are lost, shingle decay and aging can speed up rapidly. 

If this is allowed to happen, moisture will be able to seep into your home causing even further damages. 

5. If There Is Damaged Flashing 

Roof flashing is a thin piece galvanized steel that is used by roofers to keep water away from important parts of the roof. If your roof has been inspected and your flashing has separation, lifting, or dried up caulking, it can mean a bad situation for your roof. 

Through the seasons, hot and cold temperature fluctuations cause the roof of your home to expand and contract which causes the fasteners that were used to hold the flashing in place to come loose. When this happens, moisture can get past them and into your home. 

Be sure to contact a roofing company right away if you notice damage in these areas. 

Roof Replacement Timeline for Alternative Materials 

If you have inspected your roof and are ready to start moving forward with a replacement, it’s a good idea to look through a couple of roofing material options in case there might be one better suited for your needs. 

While asphalt shingles most certainly get the job done, there are other materials on the market that you want to consider. A couple of the most popular are: 


We understand that sometimes you need to make quick decisions so that your home can be protected, so hopefully, you found this information helpful as you look into your options for replacing your roof and determining how long the roof replacement process will take. 

While it may be faster to climb up on your roof yourself, it isn’t necessarily the best solution for the long-term. Instead, if you want to sign up for an inspection or to simply ask more questions about the roof replacement process, contact your local roofing company for an expert opinion.
