Trusses are utilized for stabilizing and supporting the walls, particularly in huge buildings that have more than one to two stories.
Usually, roof trusses are triangular and can be installed easily. Another advantage of roof trusses for a garage roof is that they are practical and can be used with several materials.
Learning how to install roof trusses for a garage roof isnt hard, particular if you follow particular hints and tips.
- Cutting the Timbers
The first thing you should do when building roof trusses is to cut timber panels to the garage roofs size. Measure the roofs span and check with the building project and plan.
Before you buy timber panels, you must also take into consideration the weight theyll be supporting. The reason behind it is that this will help you know their thickness. More often than not, you will have to purchase 2×8 timber panels and cut them to the size if required.

How Much Does It Cost To Reshingle Your Own Roof
Before you buy roofing materials and shingles, youll want to make sure you can afford to reroof your own roof. According to some roofing experts, a 2,200 to 3,400 square foot roof with asphalt shingles could run between $2,000 and $6,000 if you do it yourself, whereas a professional roofing company will charge around $10,000 or $12,000 for architectural asphalt shingles.
Roofing materials can cost from $100 per square to $1,000 per square. Most roofs around 2,200 square feet need 17 squares. A square is 100 square feet. When you buy composition shingles , the shingles come in rolls of square in size.
When you hire a roofing company, the removal of the old roof costs around $1 to $5 per square foot. This amounts to around $1,500 unless the contractor charges by the hour which may run you up to $80 per hour. Most of the time, a roofing contractor will factor roof removal into the total cost of the roofing project. Now, if you find rotting timber, youll need to replace the supports and this may run up to $10,000.
Fold Flashing Over The Peak
Cut the flashing back to the peak along each crease. Then fold the flashing over the peak and cover the cut ends with self-stick underlayment. Roof valleys channel a lot of water, so they need extra protection. Start by installing self-stick underlayment on the decking. This process is much easier with two people. Cut the underlayment to size , and peel off the entire plastic backer. With a person on each end, fold the underlayment in on itself, sticky side out. Then lay it into the valley and unfold it. Try to push it down into the crease of the valley as tightly as possible. If this self-stick ice-and- water underlayment bridges both sides of the decking, leaving a gap underneath, it could tear once you install the metal valley flashing. Run the underlayment past the drip edge at the eaves, and trim off the extra with a utility knife. Once it’s smooth, nail it down on the outside edges.
Finish installing felt paper on the rest of the roof, overlapping the self-stick underlayment. Be careful when you trim back the felt paper so you don’t slice into the underlayment. Photo 7 shows the underlayment covering the felt on one edge a couple of inches. This will keep water farther away from the inside corner of the fascia. You can extend the center out even more but not so far that water overshoots your gutters if you have them.

Thirty years ago, Tim, a surgeon friend of this writer, told him he could teach him within about 20 minutes to perform an appendectomy. The procedure involved a short series of steps that were so easy a trained monkey could do it opined the doctor. .
You may draw your own inferences from the fact that Tim didnt volunteer to be your correspondents first patient. The point here is that its not always wise to take on important but seemingly simple jobs, not least because complications arise too often.
True, youll be in less trouble if your roof project fails than if your friend botches your appendectomy. But you like having a roof over your head.
Replace Your Roofs Flashing
The flashing is an unsung hero of every roof. Without it, snow and rain would constantly be getting into your home. Flashing is located around chimneys, skylights, and any other parts of the roof where there is a gap between shingles. In addition, flashing is often present in roof edges and valleys.
Flashing replacements can get pretty technical, and this is definitely a repair that should be done by professional roofers or someone with a lot of experience with roofs. While a poor shingle replacement may still be able to function fairly well, not replacing your flashing correctly can have huge consequences.
Replacing the flashing will involve removing several rows of shingles in addition to the old flashing. Youll also need to chip out old mortar and caulking along the edges of the flashing. Eventually, youll seal the seam between the cap and step flashing with urethane roofing cement or a silicone caulking compound.
For a more comprehensive look at the process of replacing your flashing, take a look at this blog here.
Once again, flashing repairs are best left to an actual roofing company, as the ramifications for improper flashing installation can lead to extensive water damage.

A roof, by definition, is a dangerous place its high, usually sloping, and has no fence or rail around it. Any time you go up on a roof, you are in a dangerous situation. Therefore, when attempting to solve roof problems on your own, you should ask yourself some tough questions. Is this particular roof repair within your DIY capabilities? Do you already have the right tools and equipment? How much money would you save from a house roof replacementproject by doing it on your own? Is it worth the time, effort, and risk?
How Long Will It Take For This Project To Be Completed
A roof replacement project, from start to finish, will take between two and six days. The time it takes for a particular company varies on factors like how many people they have working at the job site or if there are any complications that need attention during the installation process.

Will There Be Any Additional Costs That Come With Having A New Roof Installed Like Permits Inspections Etc
Yes, there are. For example, if you want your roof to be a certain color or have specific features like solar panels or living plants then it will require additional permitting and inspections before installation can begin. In addition, for many people the cost of labor is more expensive than other types of home improvement projects because specialized equipment needs to be used on rooftops.
Its important that we answer this question ourselves as well so lets talk about permits: If youre building an extension onto your property then permits may not be required but if youre replacing your entire roof with materials different from what was previously installed on the structure then you might need themand depending on where you live in the United States, they might be required.
In some places the roof is not visible from the street and doesnt need an inspection but in other areas its a requirement for all residential construction projects. The inspector might do a visual assessment to make sure youre installing your new shingles correctly or check if you have enough ventilation above your kitchen stove vent hood with code-compliant vents . Inspectors are also looking out for safety issues like missing guardrails on stairs as well as ensuring that any electrical circuits being used outside comply with local codes. And remember: Every person has their own project list when replacing their roof so always get professional advice before starting work!
Picking Up The Pieces
Whether youre a new homeowner or twenty years in, owning a home can feel like a puzzle. Maybe you moved into a place with little information about the roofs last replacement. Maybe youre just learning about roof replacement materials.
All home renovations are chances to learn somethingcall it the homeowners education.
Having a timeline of the homes last repairs and replacements makes it easier to map out your upgrades list. In the event you dont know, it becomes a guessing game. Playing by ear isnt the most empowered way to own a home, so reroofing helps you start fresh.
The best home maintenance comes from preventative care, but roofs are the hardest part of the home to see. Having periodic inspections can keep your roof a part of the home upgrades conversation.

You Dont Really Save Money
Replacing a roof is a big investment. Other projects, such as a bathroom remodel or finished basement, are showier and seem to deliver more bang for your buck. Because you dont necessarily notice your roof, it can be hard to dip into your home renovation budget to replace it. For this reason, you might be tempted to save money by taking it on yourself.
However, you dont really save money when you DIY your roof. Replacing a few worn or missing shingles is one thing tearing off the entire roof is another. Professional roofers know the problem areas to look for in a roofs decking. Theyre also experts at identifying damage and providing homeowners with the most cost-effective way to fix it.
If you handle your own roof replacement and fail to spot problems, you will only incur extra cost down the road when youre forced to hire a pro to replace your work.

How To Build A Roof: Components
Most roofs are triangular in shape. Forming a strong triangle is important in lots of types of roof design because it gives the roof it’s strength. A roof also adds strength to the walls of a building.
The diagram above shows the components that go into making up a small gable roof
The ridge is a long board at the top that the rafters are nailed to.
The rafter is cut so it sits down onto the wall plate, which is in turn fixed down onto the inside skin of a cavity wall.
The ceiling joists span from wall plate to wall plate and are sometimes bolted to the rafters to help stop the ridge dropping and the roof rafters spreading.
The joist completes the strong triangle shape with the rafters.
The overhanging ends of the rafters are cut specially so that the fascia and soffits can be fixed to them.
There are other components like pinch binders, purlins and props that are added to strengthen the roof but I’ll cover those on the gable roof page later.
You may remember using trigonometry in school, I didn’t enjoy it then and I still don’t now! Although important to roofing, to know how to build a roof luckily you don’t need to master trignometry.
However, when building a roof it is important to understand that to work out most rafter lengths you need a 90° right angle triangle. A lean-to roof already forms a right angle triangle, like in the picture below

BETTER/BEST: Laminated shingles
Instead of one layer, laminated, or architectural, shingles have two or more layers with three-dimensional tabs of varying sizes. The shingles are usually the same size as the basic three tab, but a laminated shingle can weigh up to 50 percent more, which may increase durability and come with a longer warranty.
PROS: The thicker tabs vary in size and shape for more dimension and crisper shadow lines, suggestive of wood or slate. Laminated shingles offer the greatest range of colored granules.
CONS: More expensive than three-tab shingles.
PRICE: $60 to over $280 per roofing square for special shapes.*
* Shingles are priced per roofing square, which is equal to 100 square feet.
You Void Your Warranty
Most, if not all, roofing material manufacturers will not guarantee materials that havent been installed by a professional roofing contractor. The reason is simple: A botched installation that misuses the materials will inevitably lead to costly damage.
If you attempt to install your own roof, you are taking a gamble that you wont encounter any problems down the road. Even if you pull off a perfect installation, you wont have the peace of mind that comes with knowing your shingles and other materials are covered by warranty. If you need to make repairs or a full replacement in the future, you will be forced to pay out of pocket. Doing it yourself might save you a few dollars now, but it will almost certainly cost you more doing the road.
By working with a roofing expert, you know that your Owens Corning roofing warranty protects you and your wallet from damage caused by weather, wind, algae and other conditions that can cause your shingles to degrade prematurely.

Begin With Your Starter Shingles
Much of these steps are all to waterproof your roof. These steps are critical to ensuring your roof is installed properly and are all preventative measures you must take. So keep close attention to each of these.
This next step is importantinstall your starter shingles. Starter shingles will be installed overhanging the drip edge on the bottom edge of your roof. Make sure you line it up over the drip edge, with the adhesive edge on the bottom . You will use extra nails to secure this starter row. Then, when you install your first row of shingles, they will stick to that adhesive strip on the bottom, creating a perfectly tight seal impervious to ice melt and water.
How To Build Roof Trusses For A Shed
The roof trusses for sheds are one of the most vital pieces to design. These consist of 2 rafters that will hold up the structures roof. Once completed, the roof trusses are installed and lifted onto the top part of shed frames.
The trusses you require may depend upon the sheds length. The longer your shed is, the more roof trusses you will have to make. The good thing about roof trusses is that they are simple to construct.
Begin by determining the measurements of the roofs slope. This will be the rafters length. If your roof has a long slope on one of the sheds side, one of your rafters should be longer.
So, know the number of the roof trusses youll need, then double the number for you to acquire the number of the rafters youll need when building the roof trusses.
Cut the rafters from 2×4 piece of wood. Cut it to the length you require and add the plumb cut to its ends. This plumb cut should be a 45-degree angle cut.
Cut the bottom cord of the roof trusses.
Make the gussets, which are the half-inch thick plywood pieces that will cover the 3 ends of the roof trusses.

How Many Roofing Shingles Do I Need
To estimate how much roofing material you need, such as bundles of architectural shingles or rolls of synthetic roofing underlayment, you need to know the total square footage of your roofs surface.
How to Calculate Total Square Footage of Your Roof
To find your roofs total square footage:
Example #1: Shed Roof with One Roof Plane
For example, this shed roof has one roof plane.
Multiply length times width :
A x B = 40 x 30 = 1200 sq. ft. for the total square footage of the roof.
Example #2: Gable Roof with Two Roof Planes
This gable roof has two planes.
So to derive the total square footage of the roof, you would:
- Plane 1 : 40 x 30 = 1200 sq. ft.
- Plane 2 : 40 x 30 = 1200 sq. ft.
- Plane 1 + Plane 2 = 2400 sq. ft. for the total square footage of the roof.
