Code Compliance And Safety Standards Inspections

Installing the Metal Roofing – Mobile Home Roof Project

Since 1974, all mobile homes have been built to standards developed specifically for manufactured housing by the U.S. Department of Housing and Urban Development. Known as the HUD code, it is the only federally-mandated building code that exists. All manufactured homes must comply with stringent codes that address building safety and construction practices. In addition, third-party inspectors validate building procedures before the home is delivered. Each mobile home bears a permanent-affixed certification seal.

Wondering how long do mobile homes last? When installed properly, following mobile home insulation standards, a manufactured or modular home can last just as long as a regular home built directly on a construction site. Throughout the building process, quality is maintained not only by staff supervisors, but also by third-party inspectors, and any potential problems are immediately addressed. As the home nears completion, various tests are performed to ensure that all plumbing and electrical lines are working properly, that the entire building is code-compliant, and that specifications have been followed completely.

How To Roof Over Your Mobile Home

Step 1 Assess the damages

If youre not sure whether your mobile home needs a roof over, there are some common signs you should be looking for. You can tell a roof is damaged from the inside of your mobile home. Look around for light showing through cracks, dark spots on your ceiling or walls, peeling wallpaper or paint, and/or sagging in the ceiling, walls, gutters, or siding.

You cant roof over your mobile home without fixing damages first. Remember, its not like youre putting a band-aid over an open wound. Please contact a professional if repairs go beyond your skillset.

Step 2 Determine your materials

Now that youve seen the pros and cons of the most popular roof over materials, its time you choose a method that works within your budget and skill set. Many roof over kits come with an instruction kit that can guide you accordingly. While coming up with the money for repairs can be difficult for some, please dont let your budget be the ultimate decision maker. Those will less experience should hire a professional if needed.

Step 3 Research and consult a local expert

The roof over process is going to vary widely depending on the size of your mobile home, the materials you use, and the current state of your roof. With that said, we cannot provide a step-by-step guide for each method as it wouldnt fit in a single article. Thats why we highly recommend consulting with a local expert who can assess your individual needs and budget first.

Tpo Roofs Vs Competitors Roofs

Our roof over system is specifically designed and engineered for manufactured homes and low sloped roofs. There are no exposed screws anywhere on top of the roof. Even our vents have no exposed screws they are hot air welded to the roof. Our Roof Over is a true 1 piece blanket of Protection that is hot air welded to ensure no areas for water to leak into your home.

Aluminum/metal Roof Overs DO NOT COME IN 1 PIECE, they are crimped either every 4 feet or every foot. Aluminum roof over systems are not recommended for manufactured homes or low slope roofs. Theyre recommended for 3/12 pitch or steeper due to the fact that they have screws and adhesives on top of the roof exposed to the harsh Florida environment that will crack, rust and fail which creates leaks. Aluminum/metal roofs also tend to get extremely hot in Florida due to the environment. Aluminum/metal roofs are significantly louder.

When TPO is not installed properly it will ripple therefore causing problems with your roof in the future. TPO roof installation is very important and needs to be done properly.

TPO Flashing is a 1 piece flashing with no seams, caulks, or adhesives. Metal flashing is caulked and seamed ever 10 feet which is bound to fail in Florida’s harsh environment.

Adding on to an existing house may seem less expensive than buying a new one, but the truth is that it could cost just as much or even more. The best part is that you wont have to move from home when making the addition. A reasonable budget will help you stay on track and avoid overspending.

Also, remember that an addition should be a separate structure from the main home. Its foundation maintains stability and is easy to dismantle when relocating. Now, lets get into the details of a mobile home addition plan.

Only a “do it yourself” repair was economically feasible in this case.

If you were not sure of the difference between modular construction and a mobile home, notice the presence of a steel frame chassis and even wheels or wheel mounting frames located beneath your mobile home, doublewide, or static caravan.

Also notice that oil line on the crawl space floor. Is it leaking or vulnerable to damage or cold temperatures?

Mobile Modular Manufactured Whats Different

The terms are related, but there are distinct differences. The term “mobile home” is used to refer to what used to be known as “trailers,” typically small, inexpensive homes that were on wheels and could be moved from one site to another without a lot of trouble. They were built in great numbers in the years following World War II because they could be produced quickly to meet a real need for affordable housing. Their construction was largely unregulated.

Manufactured homes today are highly regulated, and although they may arrive at their permanent sites with wheels still attached, the wheels are typically removed and the homes are attached permanently to an in-ground foundation. They may consist of a single module, or two or more can be joined together to form a larger house. With skirting and landscaping, they are virtually indistinguishable from site-built homes. Structuring and building a mobile home is a very interesting process.

Modular construction is just what it sounds like. Factory-built modules that may be single rooms can be combined in many ways at a physical site. They might be stacked or joined in sequence to serve as offices, retail spaces, hotel and motel rooms, and schools as well as homes. Size limitations exist only in terms of transporting modules to a permanent site.

Reader Question: How Do I Establish That My Modular Office Meets My Local State Building Code

I bought a 12’x56′ modular office building from a government auction in sc and got it hauled to my business in NC.

But to my surprise I was told by the city code inspector, since the modular was built in the state of SC and has codes and approval of that state I won’t be allowed to get the permits until it is certified to the NC building codes. Please suggest what are my options and how can I take care of this issue.

This modular office building was built in 1998 by AAA modular based in SC or GA at the time, unfortunately seems like they are not in business anymore, it has sc stamps etc, let me take some photographs and send them over. – Anonymous by private email 2016/07/23

Reply: how to find and check the labels affixed to the structure, check with the labeling agency

Virtually every modular building construction company in North America builds their products to meet all of the state codes where they can imagine their building will end-up. Take a look at the data tags on your building. Send me some sharp photos of the data tag and a couple of the whole building and I can comment further.

Check for one or more industry / agency / manufacturing certifying labels that for any modular home or office will identify at least:

  • The manufacturer of the modular office or home
  • The modular home or office model, manufacturing date, and serial number
  • A building code compliance certification agency

Opt For More Natural Light

Home Building Facility Tour: Roof

Its worth replacing the windows if your single-wide mobile home cant access more natural light. Replacing older window models with a modern taste is also ideal for the overall aesthetic appeal. You can also choose to add a sunroom.

For a growing family, choosing energy-efficient windows makes a solid difference. You can block the heat that comes in during the summer and trap the heat in the winter. As a result, you get to save on heating bills.

Asphalt shingles

Asphalt shingle roofs are less common in the mobile home world for a few reasons, the most obvious being the weight of the material. While asphalt shingles significantly improve the overall look of your mobile home, you might be limited to adding a single layer as the weight may prove to be too much.

However, installing a single layer of shingles isnt recommended as your roof will be more susceptible to leaks and weathering. With issues like these, you may find yourself spending more hours maintaining your home if you dont have a proper warranty.

Despite these downsides, asphalt shingles still have some great benefits. Theyre very easy to install and can be quite cheap. Expect to pay anywhere from $700 $2,000 for single-wides or $1,200 $4,000 for double-wides.

A Brief Look At Mobile Home Roofing And The Required Materials

Mobile home roofing was once quite different from roofs on traditional homes.

Mobile home builders these days offer the same types of protection and the same kind of construction techniques. Its now possible to live in a mobile home and enjoy the same feeling of security because youre underneath a solid structure. The frames that support the roofs of mobile homes use 2-by-4 jousts that are overlaid with either chipboard or plywood, just like a standard home.

Be aware that those supports hold the weight of the roof. They dont make a mobile home secure from the weather. If you let those panels become exposed to moisture, they will eventually deteriorate. The insides of the home will be damaged and otherwise victimized by deteriorating panels.

Shingled Mobile Home Roof Overs

Roof Tech Talk: January 2014

A real shingle roof for mobile homes is absolutely possible for most models. They can have a higher pitch or gables too. Shingle roof overs are also installed right over your existing roof, as long as you have not already had a roof over previously.

The subject of whether its a good idea to add a second layer of shingles is much debated in the roofing industry. Be sure to get an experts opinion on your home before you make a decision. There seems to be a split in opinion on layering the new shingles over the old. Some roofing experts say you can do on manufactured homes that have 2×4 studs 12-16 OC and roof trusses that are 16 OC or less. Others roofing experts have told me they wont do it on any manufactured home.

If youre set on a shingle roof you come in a few different options and styles for roof overs, as well as several different colors and textures.

The main benefit of a shingle roof is the appearance. Shingles can dramatically improve the curb appeal of your property. Installing shingles is typically more costly than a TPO or metal roof but can improve the value a little more so you may recoup the costs.

Its not unusual to see asphalt shingles on a mobile home, particularly on homes with pitched roofs. Because asphalt is frequently used on site-built homes, many people are drawn to their appearance. Asphalt has a class A fire-rating and its available in a wide array of styles and colors.
