The Type Of Roof You Want

How To Complete a Roof Takeoff With Square Takeoff Software

The type of roof you want will have a big impact on the cost of your roof replacement. There are a variety of different types of roofs for you to choose from based on your budget and the look you want.

If youre on a tight budget and looking for an affordable roof, an asphalt shingle roof might be right for you. But if youre looking to upgrade to a longer-lasting and sharp looking roof, theres the standing seam metal roof.

Asphalt and metal are two of the most commonly seen roof types, but there are also premium shingle roofs that come at a premium price. These roofs give you a unique look that really stands out. These premium roofs include cedar shake, slate, and tile.

The premium shingle roofs can get expensive quickly and be more than triple the cost of an asphalt shingle roof.

Below, there is a simple triangle, and the math used to work out how to make a proper measurement. Once you work through the basic triangle, we will review a typical roof, and how to apply some simple math to calculate how much material you will need for a roof used in our hypothetical example.

1 roof square = 100 square feet The length times the height of a triangle is twice its area . So if you divide your answer of a product of length times height by two, you will get the area of a triangle. /2 = Area

In Figure above: l=30 feet h=12 feet /2 = 180 square feet

Now that the basic concept has been covered, lets take a look at a more complex roofing system. In this overhead view you see both a hip-end section, and gable ends. With a more complex roof such is this one, it is highly recommended that you make a basic sketch. By doing so, it will be easier to mark your measurements, and calculate the necessary materials for the project. For this example we will break this roof up into sections labeled A through E.

In the figure B. above, a sketched portion is a basic triangle. As we did in the first example, measure the length of the eaves, and the vertical line from the eaves half way point to the peak. Multiply these numbers, and then divide the answer by two./2 = 270 square feet

S1 = /2 = 135 square feetS2 = 50 × 15 = 750 square feetS3 = /2 = 135 square feet

Basic Components Of A Roof

StructureThe rafters and trusses that support the decking.

The boards attached to the roof rafters to cover the house.UnderlaymentA waterproof layer installed in between the roof decking and the roofing material.

FlashingMetal strips laid into valleys and joints of a roof, such as around chimneys or pipes, to prevent water leakage. This includes drip edge flashing, which is situated along the edge of the roof.

Roof coveringThe shingles or tiles that make up the outermost part of the roof. This can be made from many materials, such as asphalt, metal, rubber, slate or clay.

Three: Plan For Debris And Removal Of The Old Shingles By Positioning Your Trash Can Nearby You Will Also Need To Cover The Ground Beneath The Eaves With Tarps To Catch Stray Shingles

Just as the disclaimer says at the beginning of this article, use caution when working on sloped roofs. If you have any concerns about working on a roof, hire a trained professional who knows and follows all the required safety regulations.

One of the key safety practices in tearing shingles off a roof is avoiding all the debris that will be generated. All that scrap ends up making the roof surface even more difficult to move across. And the old shingles may not lift off without a fight so, be careful when prying and lifting that the shingles dont suddenly release, which can send you flying.

To help keep the roof site as safe as practical, position your trash bin in a readily accessible location, so the old shingles can just slide into the bin. Contact your local waste management company to book your trash bin ahead of time.

When you rip the old shingles off your roof, they are not likely to come off like a clean and neat old carpet, but in various sized patches. There will be bits of broken shingles everywhere and try as you might to get every bit into that trash bin, some scraps are likely to slip and slide off in different directions. And if its a wee bit windy, those bits can fly further.

So, as a precaution, its a good idea to cover the ground around the house beneath the eaves with tarps or sheets of plywood. This will help protect scuff marks and prevent damage to your homes walls and to your gardens and landscaping, and will make cleanup go much faster.

Two: Ensure That The Materials For The New Roof Are Ready And On

Roof Removal: How To Tear Off Roof Shingles With Roofing Tear Off Tools

Off with the old, and on with the new, right? This is a fairly obvious step in tearing shingles off a roof, but, occasionally, an eager homeowner may not plan ahead and get him/herself into an awkward situation. The obvious step is this: Make sure you have the materials and labor for your new roof all delivered, arranged and ready to install before you start ripping off your old roof.

Whether you intend to install the shingles yourself, or have contracted with a roofer, you dont want your roof deck left exposed after the tear-off so, plan ahead for the new roof to go on immediately. This may take a bit of fine-tuning to work around unfavorable weather forecasts and possible delays in the tear-off process.

Keep The Slope And Complexity Of Your Roof In Mind


You have to keep in mind the makeup of your roof when doing the calculation for the square footage. The steepness and complexity will change the number you multiply the footprint by.

For example:

For an easy up and over, walkable gable roof, youll multiply the footprint of the roof by 1.3 to get the square footage of your roof.

For a hip roof with a low slope, you’ll multiply the footprint of the roof by 1.4 to get the square footage of your roof.

For a steep and complex roof, you’ll multiply the footprint of the roof by 1.6 to get the square footage of your roof.

Shape And Threat Avoidance

The second operational aircraft designed around a stealth aircraft shape and materials, after the Lockheed A-12, the SR-71 had several features designed to reduce its radar signature. The SR-71 had a radar cross-section around 110 sq ft . Drawing on early studies in radar stealth technology, which indicated that a shape with flattened, tapering sides would reflect most energy away from a radar beam’s place of origin, engineers added chines and canted the vertical control surfaces inward. Special radar-absorbing materials were incorporated into sawtooth-shaped sections of the aircraft’s skin. Cesium-based fuel additives were used to somewhat reduce exhaust plumes’ visibility to radar, although exhaust streams remained quite apparent. Kelly Johnson later conceded that Soviet radar technology advanced faster than the stealth technology employed against it.

The SR-71 featured chines, a pair of sharp edges leading aft from either side of the nose along the fuselage. These were not a feature on the early A-3 design Frank Rodgers, a doctor at the Scientific Engineering Institute, a CIA front organization, discovered that a cross-section of a sphere had a greatly reduced radar reflection, and adapted a cylindrical-shaped fuselage by stretching out the sides of the fuselage. After the advisory panel provisionally selected Convair’s FISH design over the A-3 on the basis of RCS, Lockheed adopted chines for its A-4 through A-6 designs.

Why Should You Use Roofing Estimating Software

Did you know that close to 90% of roofing contractors underestimate their bids? With an accurate roofing estimating and takeoff software in your corner, you can get more accurate bids and have more confidence in your estimates. Here are 4 reasons why you should get a roofing estimating software.

  • Account for slope, hips, ridge, and valleys more accuratelyTo get more accurate measurements and estimates, your software requires much more than a two-dimensional measurement. Roofing estimating and takeoff software like eTakeoff Dimension can help make estimates much more accurate, increasing project win rates.

You can decrease the time estimates take, while ensuring that the measurements and calculations of the takeoff are accurate, limiting possibly inaccurate information.

    Use a safety harness system to prevent falls. Wear shoes with soft rubber soles for a good grip and long pants to protect against the skin-scraping shingles. Just to reiterate, working on a roof is dangerous, so be sure to take these precautions:

    • Set roof jacks and a 2×10 about 3 ft. up from the roof edge.
    • Wear a safety harness , which you can buy at safety equipment stores and some roofing and home centers.
    • Wear soft rubber-soled shoes for traction, long pants to protect your legs, work gloves, safety glasses and have the proper roofing tear off tools.

    The Importance Of Removing Debris

    While it may be tempting to shrug and assume that leaves and small branches will eventually fall off your roof, its important to remove it as soon as possible. There are two reasons. First, debris on the roof may have already damaged the roof. The damage may not be immediately obvious until the debris has been removed, in terms of pooling water and blocked gutters. Second, the debris could damage the roof in the future.

    If you have debris moving around on your roof and in your gutters, it could start redirecting rain. Debris can also become home to small pests and insects, which will eventually intrude upon and damage your home.

    Removing debris is a regular part of maintenance for a roof, but its also often best left for a professional. While they deal with roof debris, they can also check and maintain your gutters. Debris removal, as with anything to do with a roof, can be dangerous. Contact Bert Roofing today to get a quote.
