Please note that it is not always necessary to replace the entire roof. In the case of small cracks or leaks, a simple repair is usually sufficient. However, more extensive damage that extends over a larger area of the roof will almost always require replacement. In some cases, however, only the roof tiles can be replaced and not the entire roof itself.
This is, of course, a much more preferable course of action, as it will take less time and cost much less to replace the shingles than replacing the entire roof. So how exactly do you know if you can manage by replacing just the shingles or if you should replace the whole roof? The first decision is whether to simply patch the leaks and damaged areas or whether to replace part or all of the roof. If you opt for the latter, you will also have to decide whether to cover the existing roof or to remove it. Either option has financial implications - does the roof need to be replaced or is a simple repair sufficient? Here are your options, with pros and cons, and why roof replacement may be best.
However, when it comes to roof restoration, the big question is: should you re-roof or have a complete roof replacement? Well, to find out which option is best for you, let's take a look at both. If your roofer thinks you need a complete roof replacement, you have a couple of options to choose from. There are a few things to keep in mind when it comes to replacing individual shingles or the entire roof. For example, sometimes it is possible and totally acceptable to repair a roof rather than replace it.
Replacing the roof allows any problems hidden under the shingles to be detected and has a longer life span than the cladding. On the other hand, replacing the entire roof requires a great deal of labour to remove the old shingles, prepare the roof for the new installation and install the new shingles, which is more costly. Partial replacement may save you a day, but it will not help the older sections of the roof last longer. However, before you decide to replace shingles, it is important to have a professional inspect your roof to determine if any part of the underlayment or deck is damaged.
These repairs can extend the life of an old roof, and can help to bridge the time until it's time to tear off the old roof and replace it with a new one. But if the underlayment nails are missing or have come loose and the boot is in good condition, replace them with the rubber washer screws used in metal roofing systems. Most professional roofing contractors do not do half-roof replacements knowing that joining two different sections together is difficult and often ineffective. Therefore, if you see a heavy "tar patch on your roof, fix it before leaks and interior damage occur, but wait to replace the entire roof.
If the damage is extensive, it is usually a better idea and more cost-effective to replace the entire roof. That way, when the time comes to replace the roof completely, the cost of removing 2 layers can offset any savings you may have made by choosing to re-roof. A shingle that has lifted due to winds may have loosened the sealant and possibly the nail, all of which means replacing the roof. Seeing curled shingles can mean a sign of major problems, such as leaks, which may mean roof replacement.
Also, depending on age, your roof may be too brittle or worn to withstand partial replacement. When to replace your roof depends on several factors, such as wear and tear and age, the quality of the installation and the vulnerability of your home to damage in the future.
