Re-Roofing vs. Replacement

Here at Rocky Mountain Roofs, we specialize in asphalt roofing. When it comes to re-roofs on your home, you want to make sure that the proper steps are taken.

If your roof is failing and it’s time to get a new one, you may begin researching your options for the best deal. Reroofing is often touted as a less expensive option to a complete roof replacement, which could potentially save you money. Reroofing isn’t an option for everyone, however. Learning the differences between the two, and when one is appropriate over the other will help you make the best decision for your home.

When Reroofing Should Not Be Done

Reroofing is not always the best idea. Because you aren’t lifting up the existing shingles, you can’t know for certain what the roof deck looks like. While most problems can be spotted before the shingles are torn off, occasionally, there is rot or sagging that is not apparent beneath the shingles. When you add a new layer on top of the old, you are simply covering over the problem, not actually fixing it.

If only a portion of your roof needs to be done, reroofing can also get you into trouble because you will now have a section of roof that is thicker than the surrounding areas. This can mean that they don’t match up properly with one another at the ridge cap, which can be noticeable.

Reroofing can only be done if there is only one layer of shingles already in place. While you may attempt to reroof more than that yourself, or you may find a roofer willing to do it, you risk not being able to drive the nails deep enough through the many layers of shingles to hold the newest layer in place. With additional layers of shingles it also becomes harder to see what may be beneath them, so any problems may go unseen.

When Roof Replacements Should Be Done

Roof replacements can be done at any time. They should always be done if there is more than one layer of shingles on the roof, or if there are more problems suspected with the roof deck. If the shingles and roof are in very poor shape, a roof replacement is also the best answer, as it allows all problems to be addressed, rather than simply covered up.

Bottom line, there are only a few times when it is worth the saved money to get the reroofing other than a total roof replacement. Otherwise, getting the roof replaced is always the safer and longer lasting option.
