Learning how to build a roof takes an understanding of how double wide are built. Roofs have different slopes for different needs. Some need to shed water. These would be a gentle slope. Other roofs need to shed and withstand the weight of snow and ice. These require a steeper slope.
Barn-type roofs are gaining popularity because of the economic sense they offer. They are my favorite design for many reasons, but let’s discuss regular roof styles.
The slope of a roof is determined by how many inches high it is in a 12-inch span.
A carpenter’s square can help you find the right angle to make the trusses. An average and common slope for many homes is a 6 in 12 slope.
If you decide to build your own trusses, make sure you select knot-free lumber. It should be grade 1 or 2 lumber. Measure out the trusses and secure them with wood glue and mending plates.
It’s also a good idea to let them dry in some sort of press to keep them flat.
The truss will fit onto the walls. The collar beam is the part of the truss runs horizontal and is the exact distance of the span of the house. This is usually the width of the house and the collar beam is the distance from outside wall to the other outside wall.
You can secure the truss with nails or with brackets, but the sooner you brace the trusses together with cross-bracing the stronger they will be. This can be as simple as nailing plywood sheathing over as soon as possible.
You will want to close in the eaves which will allow you to cover it with the soffit and eaves.
Using Metal Roof Material and Double Wide On Your House
Building with metal roof material is fast becoming popular. It wasn’t too long ago that metal roofing only came in silver and the only buildings that used it were farm type or businesses. Now you can find metal roofing in almost any color and in a wide variety of designs.
The energy savings associated with metal roofing is amazing. It reflects the sun out in the summer, holds the heat in in the winter and makes for easy snow removal.
This bold red roof and dark wall paint is far from average or customary. You can truly let your own style and personality shine through the design and color choices.
There are different styles of corrugated double wide to choose from. Metal roofing sheets come in many sizes and colors. You can choose something that matches your siding or you can be radical and choose a color of metal that contrasts. I’ve seen great examples of both.
The real problem as I point out in other sections of the metal roof section is that the color fades after 5 or 6 years. This isn’t a real big problem anymore with the new types of paint available.
We all want to keep our house looking new, but it’s hard to keep it that way with faded metal.
Before painting the metal it needs to be thoroughly cleaned. If you skip this part the paint will start to peel off almost immediately.
If you can get a power washer or a heavy scrub brush, you can get the layer of oxidation off. The metal will look much better after this haze has been stripped away.
Once the metal is clean and dry you can start painting it. Make sure the metal is cool while you’re painting it. Also make sure that the temperature doesn’t drop below 40 degrees during the 2-day drying cycle.
I know this sounds like a pain, but it’s much better than replacing the metal. A lot cheaper too.
How To Install Metal Roof
Learning how to install metal roof material for better energy double wide efficiency is a simple process. Naturally, working with steel is harder than working with shingles because metal roofing is tough stuff. It’s really durable though and it’s totally worth the effort.
As with all roofs, you will need to lay down a layer of roofing felt. It’s best to use staples to secure the felt. It’s really important to start at the bottom and lay down a horizontal layer. Then overlap the first layer with the second layer.
Do this until you reach the top of the roof. This will make sure that any moisture that gets in under the metal will run down the roof freely.
Also as in other roofing projects, you will need to apply flashing to corners and valleys on the roof before the metal is put on. You can buy the flashing in rolls. You will need to get some good tin snips and gloves to cut the metal.
There are special metal screws that have a rubber collar. Make sure to tighten the screws down to the point where the rubber seal starts to flatten out. This will make a good weather seal. Try not to over-tighten these screws because it will bend the metal and can cause small valleys that can collect water. If you’re screwing down the ridge, be extra careful to not over-tighten the screws because this can cause the metal ridge to pull up and water might be able to get in.
Once the metal sheets are all put on, you can do final step by putting on the ridge cap.
Metal roofs last for decades if they are cared for properly. Metal can even be repainted, but it’s kind of tricky.
After a few years, the metal can look faded. If you want to paint it, you’ll have to clean it thoroughly to get the layer of oxidized metal and rust off or the paint will not adhere.
You will also need a special kind of paint for painting metal roofs.
Learning How To Install Roof Shingles
Let’s learn how we can install roof double wide properly to prevent water damage. Shingles are installed with water shed in mind and if done properly will provide an easy gravity flow pathway for rain. Shingles are really inexpensive and easy to install.
Before you can begin, you need to decide which type of shingles you plan to use. This is a question that can save a lot of money. You see, there are many different qualities of shingles, but you get what you pay for. If you live in an area that has good weather most of the time, go for the cheaper shingle.
If you live in a place that gets a lot of rain, snow or high winds, you might want to shell out for the better quality shingles.
If you have a standard roof with only one peak that runs the length of your home, the shingle job will be rather easy. For all other homes, you’ll need to prepare more thoroughly. The more ‘valleys’ you have the closer you’ll need to pay attention.
Start by attaching tar paper or roofing felt to the sheathing beginning from the lowest edge and working your way up. Make sure your upper tar paper strips overlap the lower a little. Attach with enough short galvanized nails to hold it in place.
Next, attach the flashing to all valleys and around all projecting items such as chimneys, vents, etc. Then begin the shingles at the lowest level working your way up.
Remember, you are creating a watershed environment and not reservoirs. Don’t skimp on quality here. Use the appropriate amount of nails for each shingle to avoid wind damage.
Let’s talk about asphalt shingles. They are the easiest to install and the least expensive to buy. They are also really durable.
It’s important to offset the shingles so the tabs don’t line up. This makes them shed water more efficiently.
The first row is the starter course. It is just to reinforce the edge of the roof. You can buy starter course shingles or you can just cut the tabs of and use them for the first row.
Nail the first row of shingles over the starter course. Make sure the shingle extends beyond the plywood sheathing by at least 1/2-inch so the water drips away from the eave.
Shingles need to be nailed only where the nailing assignment specifies.
Roof vent pipes need to be covered so that the rain makes a sweeping motion down the roof and away from the sheathing.
The final step is nailing the ridge cap in place.
You now know how to install roof shingles by yourself.
