What Is Reroofing?
Reroofing is the process of layering one set of brand-new shingles over a set of existing shingles. It can only be done once, so if you currently have two layers of roof in place, reroofing is not an alternative for you. This process can go be faster and cheaper than a complete roofing replacement.
When Reroofing Can Be a Good Idea
Reroofing can sometimes be a good option for property owners who have a roof that is nearing completion of its life expectancy, however that remains in overall good condition. There might be some small concerns or leakages, but no significant water damage, soggy or missing shingles, or large amounts of moss or mildew growth. It’s likewise a better choice if you are having the entire roofing system done, rather than just a partial roof done.
When Reroofing Can’t Be Done
Reroofing is not always the very best idea. Due to the fact that you aren’t lifting up the existing shingles, you can’t know for specific what the roofing deck looks like. While most issues can be identified before the shingles are detached, periodically, there is rot or sagging that is not evident below the shingles. When you add a new layer on top of the old, you are merely covering over the issue, not in fact fixing it.
If just a portion of your roof needs to be done, reroofing can likewise get you into problem due to the fact that you will now have a section of roofing system that is thicker than the surrounding locations. This can suggest that they do not match up correctly with one another at the ridge cap, which can be visible.
Reroofing can only be done if there is just one layer of shingles already in place. While you might attempt to reroof more than that yourself, or you may discover a roofer happy to do it, you run the risk of not being able to drive the nails deep enough through the numerous layers of shingles to hold the most recent layer in place. With extra layers of shingles it also becomes more difficult to see what may be beneath them, so any issues might go unseen.
