A gambrel roof is a popular roof style on many contemporary barns and sheds. Gambrel roofs are symmetrical, with two slopes on each side of the roof. If you plan on building and installing your own gambrel roof, youll have to draw out plans first to determine the proper dimensions. Once you have the plans, you can cut and construct the rafters before installing them on your structure.

HOW LONG SHOULD A ROOF LAST?ELEMENTS

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.

Assembling Your Roof’s Substrate

  • 1Cover your rafter trusses with plywood sheathing. Put down your first sheet of plywood at the corner of one end of the roof. Make sure its lying horizontally across the exposed rafters, and that the edges are flush with the edges of the end rafters. Drive a nail into each corner of the plywood to hold it in place temporarily.XResearch source
  • Most constructions experts recommend using 716 in oriented strand board for small-scale roofing projects.XResearch source
  • Plywood sheathing will provide structural support for your new roof, as well as give you a flat, stable surface to attach your other roofing materials too.
  • 2Measure and cut additional plywood to fill in any gaps in the sheathing. Plywood is sold in large sheets, which means that youll most likely need to use multiple sheets and cut them to fit. Try to cover the remaining space using as few pieces as possible, starting from the lower portion of the roof.XResearch source
  • Its important to cut your plywood so that the end of each section covers half the width of the rafter its resting on. That way, the neighboring section will fit in easily beside it, and youll have a nice solid surface to nail into.XResearch source
  • Make all your cuts with your plywood oriented the same way to ensure that the strand grain is running in a single direction. A consistent grain pattern will increase the strength of your roof sheathing.
  • Warning: Avoid climbing onto the roof until the plywood has been completely secured from the bottom.

  • Once you have the marked areas, then all you need to do is to use a drill and screws in order to secure these trusses to the side of the wall. You will have to talk with a person and tell them to help you, because the trusses need to be held if you want to secure them tightly.
  • You might need to install brackets in the wall if you have some trusses that are located at an angle. These do require a lot of attention, so do try to secure them in the best possible way, because otherwise you are bound to face some issues as time passes, especially if you are located in a region that is prone to tornadoes and other things like that.

    This Is My Personal Favorite As It Adds A Lot Of Overhead Storage Space

    Most of us have seen a number of old-fashioned barns with their tall roofs that have multiple slopes to them. What you may not realize is that this gambrel style of roof was not designed as a fashion statement. It was in fact created to build a roof that could stand up to the snows of deep winter found I many parts of the world. Although the general layout of the rafters might not seem to be that strong, the leveraged design makes them far stronger than they look.

    Having two differing slopes allows rain and snow to slide off the roof and onto the ground. At the same time, the steeper sides of the roof give you a lot more usable storage space, especially for taller items. Like the gable style roof, this one is relatively easy to build and can be sheathed in wood and covered with shingles or sheet metal for added protection and durability.

    Take a look at this how-to video:

    Pros
    This style of roof offers plenty of extra space for storage without added expenseNot recommended for areas of high wind or those with heavy snowfall
    Simple construction with two roof beams and a series of gusset jointsIf not constructed properly tend to be structurally weak
    Fewer materials mean lowered construction costsNeed to be waterproofed at the ridges to prevent leaks regularly

    The curved roof is the most time-consuming part of this project. Here are some tips to make the job go smoothly:

    • Use a jigsaw to cut the curved rafters. Don’t worry about making the curves perfect. The roof sheathing will smooth over bumps and dips.
    • The gaps between the pieces of sheathing at the ridges will allow the ridge cap shingles to curve gently over the ridges. If you place the sheathing pieces tightly together, you’ll get a sharp ridge and the shingles will crack when you bend them.
    • Cut full-size shingles into 4-in. wide strips with a utility knife, using a framing square as a guide. Each of the three tabs on a full shingle is about 12 in. wide., so you’ll get nine small shingles from each full shingle.

Therefore, we recommend you to plan every aspect form the very beginning and to make sure the plans comply with the local building codes. Work with attention and with great care, if you want to build a rigid structure that will support the weight properly.

    We strongly recommend you to use tongue and groove plywood sheets, if you want to get tight connections. Secure the sheets to the rafters with nails / screws every 6-8. In addition, if you want to enhance the look of the shed by fitting trims, we recommend you to leave an overhang of about 3/4 over the end rafters. Use a good miter saw to cut the ends of the trims before attaching them into place with finishing nails. Dont forget to check the rest of our garage building projects.

    The gable or A-frame garage roof style is the most common garage roof style.

    Garage Construction & Design

    Garage construction is essentially the same as that of a house, both in process and usually in the materials used. Though a standard garage is of course a simpler structure, it is still subject to building permits to ensure it meets code.

    Building begins with the laying of a foundation, most commonly some kind of slab. Unlike home construction, however, where walls are framed in place, garage walls are typically constructed one at a time alongside the foundation and then raised. Temporary bracing holds them in place, a mudsill is attached to the foundation with concrete anchors, and then the walls are secured to the mudsill.

    The walls are constructed with rough openings for doors and windows in typical fashion, with headers providing support.

    Ceiling joists are added to the tops of the walls to support and connect the structure. Rafters are added to the joists, and then the ridge board is added to the tops of the rafters to hold them in place. This forms the skeleton for the roof, which oftentimes matches the homes roofing and is finished in the same way, with sheathing, underlayment, and then shingles.

    The windows and doors are set in place, and then the siding is installed in this order: insulation, sheathing, building paper or house wrap, and then the siding. Finally, any exterior trim, such as the fascia and closed cornices, are added to complete construction.
