Once you know the area of the roof, you have to decide on the scope of work. Do you want to build the roof from scratch or maybe replace the old layers? You also need to decide on the finishing material. For example, asphalt shingles will be less expensive than clay tiles.

Cobalt is stronger than HSS, making it better for heavy duty drilling applications with a more rapid high-speed endurance. Cobalt also offers the advantage of being more heat resistant over standard HSS, allowing for longer running time performance when undertaking any drilling activity.

HSS is an abbreviation of High-Speed Steel. High-Speed Steel is a form of carbon steel with additional elements that potentially could include chrome and vanadium. It is most commonly used within cutting and drilling tools as an ideal economic cost-effective material for general purpose applications such as DIY jobs and small-scale projects. HSS has strong wear resistance with an increased hardness level.

For general DIY small-scale usage, on multiple surfaces and applications, HSS is the better option for the best all round, cost effective, versatile drilling process.

With so many Drill Bit options it is hard to decide which is appropriate for the task in hand. This helpful article guide will do a head-to-head comparison between High-Speed Steel (HSS) and Cobalt to determine which is the stronger and more suitable metal material for drill bit tools.

The roof area is 110.34 sq m. To arrive at this result, divide the house area by the cosine of the roof pitch: 100 / cos(25 deg) = 110.34.

High-Speed Steel Bits are more elasticated in comparison to Cobalt Bits making them more flexible and adaptable for different drilling scenarios. Cobalt Bits are more brittle and so are susceptible to chipping.

Cobalt is a combination of an alloy (typically Steel) mixed with Cobalt. Cobalt (symbol – Co) is a chemical element found within the Earth’s crust as a chemically combined form. It has an Atomic Mass of 58.933195 u and a Melting Point of 1,495 °C. The metal is within a group of transition metals as one of only three ferromagnetic transition elements alongside Iron and Nickel. The strong mass and high melting point makes it a hard metal ideal for the toughest applicational uses.

After you've made all of these decisions, it's best to contact your local contractor and ask about the cost of both materials and labor per square meter or square foot of roof area. Remember that this unit price should include all additional elements such as fasteners, as well as the cost of removing all layers and disposing of them (if applicable).

The standard roof pitch is between 10 and 25 degrees. Choose a higher value (steeper roof) if you live in an area where it snows a lot: the snow will slide off the roof more easily.

The high durability of Cobalt material gives the Cobalt Drill Bits a long-lasting lifespan. Cobalt Drill Bits also have strong heat resistance allowing for deep drilling into tough metal material. Quality Tools UK offers tips, guidance and advice on drilling through materials such as Hardened Steel, Aluminum Drilling and Titanium Drilling. Check out our blog posts here.

HSS Drill bits are a more economical option in comparison to Cobalt Drill bits and is the most cost-effective drill bit type available. Making HSS Drills more suited for the general multi-purpose use activities such as small-scale DIY tasks. Cobalt being a more expensive option are typically used by professional construction users and trades personnel for specific purposes.

The most typical cost of roofing falls between $2 and $4 per square foot (including labor). If the price proposed by your contractor deviates from these values, it is advisable to check with other contractors before starting the work.

However, for challenging Steel, Iron, Bronze or Titanium it is recommended that Cobalt should be considered for its high heat resistance and longevity when drilling.

The roofing calculator allows you to determine the area of the gable or shed roof of your house and to accurately estimate its cost. All you have to know are the dimensions of your house and the roof pitch, and this roof cost calculator will do the rest for you. Let's get started!

The last thing you have to do is to multiply this cost by your roof area and voilà, you now know the total cost of your roof! Remember that the real cost might differ from this value a bit due to waste, so plan ahead and assign more funds to this construction work.

Cobalt is suitable for stronger metal drilling, such as Hardened Steel, Stainless Steel, Cast Iron, Bronze and Titanium as well as being well suited for drilling through weld seams. HSS is better for the lighter metals as well as wood and plastic applications. The Cobalt drills will not be adequate for the use within wood or plastic as it would cause damage to the surface material, whereas HSS would not be the most adequate material for cast iron, bronze, titanium or hard steels as it could potentially wear damage to the drill bit.

Once you know these values, you will be able to calculate the roof area. Begin by converting the roof pitch to an angle expressed in degrees using the following formulas:

All orders placed before 5:00pm Monday to Thursday and 3:00pm Friday will be dispatched on a next day carrier service. Carriage is free on all orders over £50 (Excluding VAT), if below £50 then next day delivery is £6.50

? If you are building a roof, our rafter length calculator may be just what you need. Or if you get a lot of snow where you live and ensure your roof can cope, check out our snow load calculator.

If you cannot contact any contractor, calculate the cost of materials (for example, by going to the nearest construction store) and multiply this price by 2.5. You will obtain an approximate price including labor, assuming that 40% of the cost is taken by the materials and 60% by the labor.
