roof replacmentNow that you need brand new roofing but want to save up money, what do you do? Do you put a new roof on an old one? Although this strategy is rather common in most places as well as numerous professional roofers do not see any issue with this, it is not a good practice. Why? Here are some of the leading factors why a layover is not a good idea when getting a roof replacement:

Areas that have or had leakages cannot constantly be dealt with correctly

There is a likelihood that your old roofing had some problem areas such as leaks, whether you see them or not. Without detaching the old roofing and properly addressing the issue or its root cause, you may not repair the issue correctly.

It is not advisable to add some roofing weight on old rafters

One of the most apparent issues with a lay-over re-roof is the included weight of the added layer of roof shingles. Maybe for newer houses, this may not be a concern, however, for older houses with almost worn-out rafters may not be able to support the additional weight of an additional roof.

It is not unusual to see 2 × 6 rafter systems on a lot of these homes but there are instances that a 2 × 6 rafter is undersized to start with. You would not want to add the weight of a brand new roof over an old one that is smaller.

Any kind of deteriorated wood under the existing roofing will just become worse

There might be areas in your roof that have decayed wood hidden underneath. Most often, these decayed wood are hard to locate and determine even before a new roof installation. If your professional roofer is just doing a layover, then these decayed areas will continue to stay hidden and just become worse over time. Additionally, the nails holding back the roof shingles in place with decomposed wood will not secure or hold the roof in place.

Your roofing may have a shorter lifespan

If you ask professional roofers, they are most likely to agree that a lay-over roof covering will certainly reduce the brand-new roof covering’s life by about 25%. This reality alone implies that any kind of cash you could have conserved by doing a layover, instead of a tear-off was just a short-term cost-saving. On top of that, you now have two layers of the roof that will need to be removed the next time you get a roof replacement Myrtle Beach.

Removing the old roof and installing a new one is the best way

While lay-over roofing may save you money now, in the long run, it will cost you more to remove the old one than buy a new roof. MB Roofing Pros does not advise on doing this. We constantly suggest totally tearing off the old roof covering, dealing with any type of underlying issues, then mounting a fresh, stunning brand-new roofing that will outlive any kind of lay-over roofing system in addition to better safeguard our consumers’ houses.
