Replacing parts of a roof often depends on a variety of factors. After your contractor has assessed the condition of your roof, both underneath (in your attic) and above (the exterior roofing conditions), he or she might decide that one approach makes more sense than the others. Here are two approaches to replacement roofing and why your contractor might select one over the other.
Patch Replacement Approach
You might have a section of roof that looks torn up or badly beaten. You may think that your entire roof has to come off and be replaced, but that is not necessarily the case. If your contractor does not notice any structural damage to any other areas of the roof, and there are no signs of water damage, mold or mildew, then he/she can do a "patch job."
Simply put, the contractor and the crew will only pull off the bad sections of roofing material and replace these sections only. As long as the trusses underneath are still sound, the contractor only needs to replace the messed up sections. If part of a truss needs repair as well, that can be included in the patch job so long as the little section of truss is not going to cause other issues with the parts of the roof that do not need repair or replacement (e.g., the truss is already bared because the damaged roof section was just over the top, which makes it easy to get to the damaged truss and repair it).
Whole Roof Replacement
You may not have expected a total roof replacement when you called your contractor, but now you may find that that is exactly what you are getting. Why would a contractor look at one small section of damaged roof and decide that the whole roof needs to go?
It could happen for any of the following reasons:
- There is severe water damage that has crept into other areas of the roof. While you cannot see it from the ground or on a ladder, your contractor spotted it during the initial inspection.
- More than one truss or support beam was affected by the damage on your roof. If two or more trusses are damaged, then more than just a small section of your roof needs to come off.
- There is a lot of mold and mildew damage spread throughout your attic and the roof itself. Mold remediation crews simply cannot rescue your roof and make it cost less than a replacement roof, so it makes better sense to remove the old roof entirely and start from scratch.
Usually, the more severe the seen or unseen damage, the more likely you will need your entire roof replaced. Contact a roof contractor, like Empire Roofing, for more information.
