How To Build A Shed – Part 4 Installing Sheet Metal Roof

Corrugated tin roofing panels are effective for reducing the weather-related deterioration of some older roofs. Depending on the building codes and neighborhood covenants in your community, you may not be able to put a tin roof cover on a residential house if you live in town, but you can probably cover a storage shed or a small outbuilding roof. The nice thing about tin panels is that you can install them directly over the existing roof after attaching nailing boards, called purlins. Retrofitting the new tin roof saves tear-off labor and eliminates roofing waste disposal fees.

How Do I Know My Roof Needs To Be Replaced

To determine if your roof needs to be replaced, start by inspecting the roof. If you see cracked or warped shingles, the roof will need to be replaced before a leak occurs. To check that the shingles remain flexible: Slide a flat pry bar or trowel under the shingles to loosen the adhesive.

Mansard roofWhy you should consider a mansard roof? The main purpose of sloping ceilings is to have more space. In principle, you can add a flat and a small but nice apartment, such as an attic, etc. This also saves you costs and sometimes taxes, as you mentioned above. So if you need more architectural space, an attic roof is ideal.What does mansard roof mean?Attic roof. A dormer or mansard roof is a four-sided

Position And Fix Venting

Once your metal panels are in place its time to cut any holes for your roofing venting, chimney or other outlets. Use a jigsaw with a metal cutting blade they have lots of small teeth. You can also use power shears or tin snips, but youll need to then use a different saw to cut through the roof sheathing.

When you install your vents or chimney be sure to use lots of silicone above and below the opening.

Measure The Roof Area

You will need to order enough metal material to cover the entire roof, and this process starts with measuring the full size of your roof .

You can measure the size of the roof from the ground, but its far more effective and efficient to measure it from on top of the roof itself.

Once youve arrived at a total square foot estimate for the roof, the next step is to add on an additional 10 percent to take into account potential waste .

Does A Deck Add Value To A House

Although a deck can help increase the resale value of a house, many homeowners dont choose to install one for purely financial reasons. Decks add value in other ways, including whats considered the joy factor, which helps improve the livability of homes. Installing a new deck may seem like a big expense, but it can be worth it in the long run.

Types Of Metal Roofing

Before we get into the steps on how to install metal roofing its important to understand what types of metal roofs exist. While metal roofing can be made from a variety of metals, tin, zinc, steel, aluminum and copper are the most widely used and most commonly available options. Each metal has its own advantages and disadvantages, as well as cost considerations. Steel, for example, is the least expensive option while copper is the most expensive.

In addition to material choices, metal roofing is also available in three design styles: through-fastened panels , modular panels and standing-seam panels.

  • Through-fastened corrugated metal panels are the most common and readily available type of metal roof. They can be installed over roof sheathing or purlins.
  • Modular panels, which mimic other roofing materials like asphalt shingle and tile, are also available in a wide range of colors and styles. They, too, can be installed over solid sheathing or wood battens.
  • Standing-seam panels install over solid or skip sheathing and have the most complex installation process, so are typically best left to professional roofing installers.

What Are The Three Types Of Trusses

There are different trusses available based on their position and usage. However, three types of trusses are most common in constructing buildings. They are:

  • Roof Truss: It constitutes the structure of the roof. Besides, it is used for creating the roof of a building.
  • Floor Truss: Floor trusses act as support for the foundations of the building.
  • Space Truss: Space trusses are used for overall stabilizing the building structure.
  • The Corrosion Protection System Influences The Life Of A Shed Roof

    How To Install DIY Metal Roofing (House or Barn)

    The basis of the system is a zinc coating, called galvanising. This coating creates a sacrificial layer on the steel that protects the bare steel beneath. A typical coating thickness is 275 g/m². This layer of zinc is gradually worn or washed away when it is exposed to the elements. Once the zinc coating has broken down the steel will begin to rust. However if the zinc coating can be protected then the life span can be greatly extended.

    A typical polyester paint system will extend the time to first maintenance in a coastal environment from 1-5years up to 10-15 years.

    A PVC Plastisol coating is more durable still and can give a time to first maintenance in a coastal environment of 15-25 years.

    In addition there is significant evidence that when choosing a paint colour that a light colour will last significantly longer than a dark colour. A light colour can have a time to first maintenance twice that of a darker colour. The reason being that the light colour tends to reflect the heat and suffers less thermal stress than a dark colour.

    A lot of elements play a role in maintaining the integrity of the roof, but as a homeowner, the most important components to pay attention to are the underlayment, ventilation, and material.

    Covering A Slanted Roof

    The next step of how to build a slanted shed roof should be the roof covering on a wooden decking. A variety of roof materials give a great fantasy flight. There are some of the most suitable and their distinctive characteristics.

    • Floor decking inexpensive and excellent protection from rain and snow.
    • Slate long operation for at least 30 years easy installation. The downside is that it is not always advisable to use for small-sized sheds.
    • Seam roof very easy to stack, as it is a thin metal sheet easy to install but it is quite expensive.
    • Tile or shingle looks nice, but is suitable mainly for large sheds, which are made of stone.
    • Different roll materials very simple in styling, perfectly protect a construction from the rain are durable and serve for a long time and differ with the cheapness.

    Important! As a slanted roof often has not very big angle of inclination, it constantly accumulates water in the rainy season or winter. In order to avoid various troubles, you should mount in the roof a heating device, heating a roof from the inside and not allowing a large quantity of water to be accumulating at the surface.

    Measure and cut 1-by-4 treated boards to match the width of the existing roof. If youre covering a large barn roof, you may need several boards for each nailing strip.


    Start at a bottom corner of the roof and position a 1-by-4 board even with the edge and flush with the bottom of the existing roof. Insert two 16d nails, evenly spaced, through the new board into each rafter.


    Install additional 1-by4 boards until you reach the opposite end of the roof to complete the first purlin. Cut the last board to fit with a circular saw.


    Move up 30 inches and install another purlin using the same method. Continue adding purlins every 30 inches up the roof until you reach the roof ridge. There, install a 1-by-8 purlin at the top of the ridge, even if the last purlin was less than 30 inches away. Attach purlins to the other side of the roof the same way.

    The roof deck can be retrofitted with fasteners. When high winds create negative air pressure, the roof deck can be sucked right off the trusses and rafters.

    Roof deck fasteners can be screws, staples, 8D nails, and others that anchor the metal roof decking down. By making all the retrofits above, your metal roof will have the best chance during hurricane-force winds.

    The Basic Construction Process

    To build a flat roof, youll want to have a thorough understanding of how the process of constructing the flat roof works and the different methods available. That will help you remember certain factors and details to build the best possible flat roof.

    Having a manual for warm flat roof construction with details and a summary of rules to follow helps.

    The basic construction of a flat roof starts with roofing timber that is laid across two upright items, usually two walls.

    For additional stability, you can also use steel joists that are built into one or both of the walls. This will give additional stability to the roof structure.

    Then, this roofing timber will be placed on top of the steel joists, which are built into the walls. In some cases it is actually cut into the steel, but in most cases it will be simply laid on top of the steel joists.

    Depending on the size of the roof, the joists are placed a specified distance apart to minimize the weight-bearing load on any of them.

    You can often consult an online chart to find the optimal distance based on the width and span of the roof. Generally speaking, the bigger the roof, the more joists you will need to hold up the roof.

    You will then add a plywood covering over the joists, what some home professionals refer to as the decking. Again, the width of the decking will depend on a number of factors that will impact how sturdy the roof is.

    Prepare The Roof Surface

    You can use metal roofing over old shingles. If you opt to do this, youll benefit from using furring strips and a waterproof barrier first. If you think that is overkill and youll have an unheated shed, then you can screw directly through the shingles.

    Again, if you opt for battens, then you are reducing the weight of your structure and increasing the likelihood of condensation beneath your roof surface. Battens, however, are cheaper than solid decking and totally adequate for a simple, unheated shed.

    Underlayment is not necessary, as mentioned above, for an unheated shed. You can screw your metal panels directly to the surface of your sheathing.

    Finally, as you prep the roof surface for underlayment and/or your metal roof panels, plan out any roof venting that you intend to install. Mark it out but do not cut a hole yet. You will make your cut after the roof is installed to ensure the sheathing and metal roof panel cut align perfectly.

    How Much Does A Metal Roof Cost

    To the surprise of many, some metal roofs do not cost much more than an asphalt roof. The difference often lies in the installation costs. Simply put, more roofing companies do asphalt shingles. The more competition, the lower the price.

    If you are using a commonly found brand and style of metal roofing, then expecting to pay around more than you would for asphalt shingles. Of course, that price can balloon if you want a different color, style, or brand of tin roof.

    For instance, one square of asphalt roofing will cost around $100. Metal panels are commonly found in 10, 12, and 16 lengths. A panel that is 10 long and 36 wide would require 3.5 panels to make a square. If one panel is $30, then you are looking at about $115. Of course, that is for the cheapest type of metal roofing.

    Which Is Better: Steel Or Aluminum Roofing

    Why Should You Choose Metal Roofing

    Metal roofing is a common choice for sheds because of how long it lasts. Generally, metal roofing can last 50 or more years. Compared to the 20-25 year maximum lifetime of regular asphalt shingles, metal roofing is the choice for the long haul.

    There is also a safety benefit to metal roofing in that it is highly fire resistant. That can only be good news in the context of a shed which often can contain flammable materials and sits in the sun. How much your metal roof will cost is based on the type of metal you choose.

    Type of Metal
    Zinc $5.50-$12

    Generally, shed roofs wont measure more than 80 to 100 sq. ft. Corrugated metal roofing, for example, would only cost you between $136 and $200 for an 80 sq. ft. roof. That alone is why so many builders opt for metal roofing. More expensive metals, like copper, can cost you between $960 and $1,920 for an 80 sq. ft. roof. Inexpensive metals like corrugated metal, steel, tin, and aluminum are quite effective and easy to install.

    Why Do People Build Flat Roofs

    When most people think of roofs for their homes, its natural to think of classic pitched roofs. However, there are several reasons why homeowners might need to consider and design a flat roof installation:

    • Zoning or planning ordinances restrict the height of new construction
    • Building a pitched roof would block sunlight
    • Creating a home extension results in a structure like a shed that fits right up next to an existing building, leaving no space for a pitched roof

    You can think of a flat roof for a garage extension or shed that connects with the main house as an example of a flat roof installation project.

    Some architectural styles that feature big, boxy designs would be a natural fit for a flat roof.
