How to Know When to Replace Your Roof, When to Repair

When to Replace Your Roof, When to RepairThe winter months can be particularly hard on your roof. Between record amounts of snowfall, powerful fronts of artic cold, and chilling blasts of high speed winds, people and buildings alike have taken a beating. It’s likely you may have experienced a leak or some shingles are dislodged or torn. Some of these can be handled with easy repairs. However, others may find the time is nearing where it would be wise to consider an entire replacement.

Know Your Roof

Ultimately you will need to find a reliable contractor whose recommendation you can trust. But before you do that, it would be prudent to do some analysis to see where your roof stands. While you may not have the eye of a trained contractor, you can get a general idea of the condition and severity of the damage which is present. This will make it easier to find the right contractor and have an informed conversation with him.

How Old is Your Roof?

One major factor in determining if you should replace your roof is the length of time since it was installed. This should weigh heavily into your decision. If you have shingles with a 20-year life expectancy and they were installed 18 years ago, it might be more cost efficient to replace the entire roof now. Unfortunately, roofs only last so long.

Signs of Repairable Damages:

Here are some things which may be repairable.

  • A few shingles missing after a wind or snowstorm
  • Minor leaks

Signs You Should Consider Replacing:

  • Major leaks with serious interior indications of damage
  • Rust on flashing
  • Worn around chimney
  • Piles of grit from asphalt tiles
  • Sagging roof deck

Cost Comparison / Pricing Repair vs. Replacement

The cost of replacing an entire roof will obviously be more expensive. On the other hand, repairing or replacing it piece by piece can actually cost more in the long run and be more hassle. This is similar to deciding whether it is better to buy a new car than continue to repair an old one.

Why You Should Repair Your Roof

Here are some advantages to repairing your roof:

  • You will pay a much smaller lump sum.
  • It can add several years to your roof’s lifespan.
  • Repairs have less work time.

Even if you can’t do the repairs yourself, it will be the less expensive option.

Why You Should Replace Your Roof

Here are some advantages to replacing your roof:

  • Will have full 15, 20, or 25-year roof lifetime.
  • Often more cost efficient per shingle / square foot.
  • All shingles and replacements will match.

Mismatched shingles will certainly keep the water out of your house as well as color-coordinated shingles. However, it is important to consider if you are going to sell your house in the next few years. Not only do mismatched shingles reduce the aesthetic appeal of the house, they might leave potential buyers with uneasiness regarding the integrity of the roof.

Most of these factors will carry different weight depending the particulars of your situation and future plans. There are pros and cons to either choice, and it ultimately comes down to what fits the needs and condition of your roof and your budget.

  1. My sister recently purchased a home at an auction. When she arrived at the house, she noticed there was some damage to the roof, and she wants a professional to take a look. I didn’t realize a professional roof repair service can fix minor leaks and missing shingles quickly and cost effectively. I’ll be sure my sister is aware of this option.

  2. In your article, you stated if you have shingles with a 20-year life expectancy and they were installed 18 years ago, it might be more cost efficient to replace the entire roof now and unfortunately roofs only last so long. When I came home from work last night I found some shingles in the front yard that came from our roof. I wonder if there roofing materials that are more durable and can last longer.

  3. If your roof has a major leak with interior signs, I can see why it might be time to replace. That would mean your roof isn’t stopping water. Water damage is a big deal, too; that water can weaken your roof.

  4. I like that you point out that one of the reasons to repair your roof instead of replace it is that you won’t have to pay as much. I can see why this would be nice if you are trying to save money for other things and don’t have extra money to use on the roof. This might also be a good option if the damage is something small. However, I think that if there are several things wrong then perhaps replacing the roof would be the better option.

  5. This is some really good information about replacing your roof. My roof is a little beat up and I have been thinking about replacing it. I liked that you talked about how a new roof will last ten to fifteen years. It does seem like a good thing to have a professional roofer do for you.

  6. I appreciate you talking about how considering the age of your roof can help you decide if it is time to replace it or repair it. It makes sense that taking the time to consult with a roofer can help you assess the situation properly is you don’t know much about your roof. Do you know how long it takes to replace shingles? I want to make sure I make the time to clear the area in order to avoid accidents.

  7. Good advice for when to repair and when to replace your roof. Knowing the difference can save everyone a lot of time and even money.

  8. My husband and I just closed on our first home, and we are really excited to start fixing it up! The first question we have to ask whether to replace or repair the roof. I like the point you made about total replacement being more efficient if you consider the cost per square foot. Plus, you are right about the benefit of not needing to worry about the roof for the nex 20 years. We might as well replace it now, while we are fixing the rest of the house up!

  9. I like how you mentioned that there are advantages to repairing your roof. It was helpful that you included that repairing it can add several years to your roof’s longevity. My grandmother recently noticed that the shingles on the side of her house were starting to curl upward. Looking into having her roof repaired could be very beneficial to her.

  10. Scheduled inspection of the home roof could prevent you from spending a huge amount of money. I always hire an experienced professional for check up and do the repairing if needed. I have seen most of the homeowners are not aware of the basics of the home roof. Hence they don’t able to make the right decision. Spending money without any need would not bring any benefit to you. You should first know whether the roof needs to be repaired, partly replaced, or fully replaced. Anyways, thanks for showing the cost comparison—pricing repair vs replacement.

  11. I like your advice to take a look at where your roof is and how much damage has been done. That way you can have a bit of an idea of what needs to be done when you hire a roof repair service. You might even be able to direct them to which spots need the most work which would help them save a bit of time on the project.

  12. I like your comment about replacing your roof, and how it will give you a full 15, 20, or 25 years. It also sounds like depending on how old your house and roof are, it would be more cost effective to just replace the roof. I am going to find a roofing specialist to come look at my home next week. My roof is 20+ years old!

  13. It’s good to know that the age of a roof plays a large part in whether you should get a roof repaired or replaced. My roof looks like it got damaged just recently, but I wasn’t sure if I should get it repaired or have the whole thing redone. Would a good roofing contractor be able to determine what age my roof is?

  14. My husband and I just recently bought an older home. The roof is in need of a lot of work. Thank you for suggesting repairing the roof will save us more money then if we just replaced the whole thing. I will have to do some research on roofers in my area and find one that can get the roof looking amazing again.

  15. Thank you for mentioning that one indicator that the roof needs to be replaced is if the rood deck is sagging and the leaks are too much that they actually damage the interior. The sagging roof deck is not really that obvious, but the damage in the interior can be seen by just about anyone. The attic, especially, is the one that has received the most damage. That is why I think it will be best if I spoke with the boss and ask him to have the roof of the firm replaced.

  16. I like how you said that doing residential roof repairs is good because you will end up paying much less money at a time. My wife and I have noticed that we have a bit of a leak in the roof and we want to get it fixed before it develops into more of a problem. We’ll have to hire a company to help with the roof repairs.

  17. I appreciate it when you said that each roofing material has their own life expectancy and that the person should consider replacing it if it is nearing their limit. The roof that we are using has been installed before I was born 23 years ago. It is not showing any sign of a problem, though I will still try and ask my parents to replace it since it is bound to start failing soon anyway. What do you think?

  18. Thanks for pointing out how people should have their roofing replaced if they have had a good, 15 to 25-year run with them. My dad has been living under the same metal roofing since I was little. I think he is now due for an upgrade, so I will be sure to advise him to have his roof replaced soon.

  19. If one of the factors in determining roof repair is the how old it is as you said then I need to ask my husband how old that roof is before we moved in. Since you mentioned that minor leaks are a sign of repairable damage, I don’t think we’ll have any problems contacting a contractor to repair the roof for those. I do agree that repairs have less work time as you pointed out especially if they’re done by a professional so I might consider having it repaired next week if anyone’s available.

  20. I love what you said about roof repairs and how these are important when it comes to minor leaks and missing shingles. Repairing a roof can be dangerous, so it’s important to leave it in the hands of professionals. My neighbor’s roof is missing quite a few shingles, so I’ll help him find a reliable repair contractor that can take a professional look.
