Can You Put Two Layers Of Shingles On A Manufactured Home

How many layers on a roof

The process for installing shingles on mobile homes is exactly the same as site-built homes. However, on site-built homes, two or three layers of shingles are acceptable. On a mobile home, one layer is the limit. This means, if your shingles need replacing, thats exactly what you need to do remove and replace them.

Everything You Should Know About Home Roof Replacement In Nj

In New Jersey, violent thunderstorms, blizzards and intense low-pressure systems put residential roofs to the test. High-quality materials and expert installation are very important in a state where temperature extremes range from a historic high of 110 degrees to an all-time low of minus 34 degrees.

Since roof replacements on any given home usually happen decades apart, the average homeowner does not always know about the various steps involved. A little upfront effort to learn about the process is well worth it. Once your home roof replacement is complete, youll enjoy what a new warrantied roof provides.

The Roofing Contractor Has To Use Your Current Roof Flashing

Roof flashing is metal material placed anywhere the shingles butt up against something, such as a wall, chimney, or in open valleys. It’s a crucial roofing component that every roof needs to have.

When you get a nail-over, your current contractor must rely on the flashing already on your roof and the past contractors workmanship. If the metals integrity is compromised or the work was done poorly, you should not get a nail-over.

If they use the compromised flashing during your nail-over, you will have leaks. This leads to spending even more of your hard-earned money on repairs and replacing the flashing.

If youre considering a nail-over, ask your roofing contractor if they saw any problems with your roof flashing.

    Pros And Cons Of Layering Roofing Materials

    There are several benefits to adding another layer of roofing materials to your home. In many cases, it does save time on the project since you will not have a day of tearing off existing materials. Along with that, you dont have to worry about disposing of the old shingles and other materials. More importantly, it is a cost-effective option.

    The drawbacks of adding a second or third layer of shingles are significant. Typically, finding leaks and repairing the damage on a single-layer roof is straightforward. Many residential roofing contractors can fix the problem within a few hours. Fixing a double- or triple-layer roof is more complicated. Water leaks are harder to find. Once the leaks are discovered, they can be harder to repair since the water has saturated several layers of materials. As you have guessed, these repair jobs are more expensive and time-consuming.

    When Is Reroofing Not A Good Idea

    A professional and honest roofing contractor willand should always warn you if your roof is not a good candidate for an overlayor reroofing. That is what a roofing inspection is for and should always bedone before any action is taken on the roof.

    After a thorough inspection, a roofer will come to you with his report or a recommendation, explaining why your roof is or isnt up for reroofing. You can ask for a few roof estimates from different contractors just to be sure that you are doing the right thing, so that you can choose the best roofer for yourself.

    One of the main and most straightforward reasonswhen an overlay is not possible is when you dont have asphalt shingles. Installinga new roof over an existing one can only be done if you have shingles becauseyou can only put shingles over shingles. It is not possible to mix materials,nor to install a new layer over slate or wood tiles.

    Another reason is curling shingles, as you can onlyinstall a new layer if the first one is completely flat and level. Shingles cancurl over time due to different reasons, so if you still want to go with theoption of reroofing, you should first get to the bottom of this problem withyour roofer and replace the curling shingles.

    Why Not Add New Roof Shingles Over Old

    As suggested above, the potential cons of re-roofing tend to outweigh the potential pros, but it all depends on your situation. The following list includes some universal reasons not to reroof as well as some considerations or things to check out if you’re seriously considering adding new roof shingles over old ones.

    1. Shingles are designed for flat surfaces. They don’t do a good job of bridging over gaps, dips or humps, including the stepped texture created by overlapping shingles. Re-roofers have tricks to lay new roof shingles over old so that the same step-ups between courses are maintained, but if any old shingles are cupped, curled, or otherwise misshapen, those defects will “telegraph” through to the new layer. Many roofers recommend using laminated, or dimensional, shingles for re-roofs because they’re thicker than standard shingles and often have a staggered edge profile that helps hide any dips or high spots in the old roofing.

    3. No visual inspection of roof sheathing. Without a tearoff, roofers can’t see what the decking looks like. A good roofer will perform a careful “walking” inspection for spongy areas and other problems, and they can make localized repairs before re-roofing. A not-so-good roofer might be less conscientious.

    5. Re-roofing may affect the warranty on the new shingles. Pretty self-explanatory. Be sure to check with the shingle manufacturer regarding all warranty issues and installation requirements before re-roofing.

    Difference Between Reroofing And Roof Replacement

    Roofing over an existing roof is also called reroofing or an overlay. It is the process where roofers install a new roof over your existing one, i.e. add a new layer of shingles, which means that there is no tearing off of the old roof. It is important to know that this process can only be done once because you can only have two layers of shingles on your roof.

    Roof replacement is the process of installing acompletely new roof that includes tear off of the old one. Roofers will teareverything off, down to the deck of the roof, and basically start from scratchwith the new roof, from putting felt paper to installing shingles. Since roofreplacement includes tearing everything off, it can be done on every roof, nomatter the number of shingle layers they are all going to be removed in anycase.

    Roof replacement involves much more time and labor,and is, therefore, more expensive than reroofing. When a roof has no underlyingproblems, when it is old, and is simply losing its function, reroofing might bea better solution as it involves much less work on your home, as well as lessmoney.

    How Many Layers Of Shingles Can You Add To An Existing Roof

    Depending on your community, specific building codes may be in place for your roof. Some regulations allow for only two layers of roofing. On those steeper roofs, you may be able to add a third layer. You could even face restrictions on the types of roofing materials used for your home. In many cases, multiple layers of roofing materials can be placed on your roof. However, adding a second or third layer is not always a good idea.

    Before adding more materials to your roof, find out how many layers are currently on the home. If you already have the first layer, you could have the roofers add another one. For homes with a second layer, you might be pushing your roof to the limit and need to schedule a complete teardown.

    How Long It Would Take To Install A Layover

    The same factors that influence how long it would take to install a layover are the ones that influence how long it would take to do a full replace.

    Pitch: Pitch is a measure of how steep your roof is. The steeper your roof the longer it will take to install your layover because of safety concerns. This would be especially the case with an older roof because the crew would be walking on damaged shingles. A potential reason a layover wouldnt be possible!

    Complexity: It takes more time to install a layover on a complex roof. Each part of the roof is known as a facet. The typical A-Frame roof has two facets: one on each side of your home. A complex roof is aesthetically very appealing, and it would be somewhat of a waste to do a layover since the second layer of shingles wont lay flat, wont look the same as the first layer, and will be more prone to curling, peeling, and blow offs, all of which will make your roof look less nice.

    Flashing: Anyplace that breaks up the contagious nature of roofing material is a place where youll find flashing galvanized steel or aluminum that prevents water damage. If roof protrusions and the areas where the roof meets walls are what inspired the need for flashing, then you can only imagine how much more vulnerable to water damage your roof will be given that a layover will cause more protrusions. After all, youre literally creating more protrusions and more points of contact between your roof and wall!

    Cant Inspect Underlying Materials

    Foregoing the cost of tearing off the old shingles means that you are also foregoing a chance to inspect the underlying materials. While shingles are the part of the roof we think about the most, a roof is not just made of shingles. Decking, underlayment, flashing, etcall lie below the shingles and are just as important. When you fail to remove the shingles and inspect these materials when installing a new roof, you miss the opportunity to catch weak points. These weak points include rotting plywood, tears in the underlayment, or rusted flashing. All of which can cause unexpected, and costly damage. The longer they go un-repaired, the high the chance they will develop into leaks, cave-ins, or mold.
