How to get Roofing Estimate?

In Construction, the standers pitched roofing vary vastly all across the globe. Different terrains demand different types of materials and techniques.

The same is the case for roofing estimation. Although the pitched roof is the most common form of roofing estimation used, yet there are variations according to different needs in different parts of the world.

Many areas require inclined or slope roofs due to climatic conditions or other factors. The degree of slope affects the installation techniques of the roof, as well as its waterproofing and maintenance.

What is the difference between Slope roofing and Flat roofing for roofing estimation?

What are the Pros of slope roofs?

• Inclined roofs are fairly more resistant to heavy snow, water and wind.
• They are 15 times more compact than flat roofs, resulting in greater protection and better thermal insulation.
• Tilted shape of these roofs gives more stability and strength to the building as compared to other forms.
• They provide better drainage of rainwater, yet, also making it easier to collect, modify and recycle externally drained rainwater.
• Their maintenance is less costly than flat roofs.
• Most materials can be easily adapted for sloping roofs.
• If needed, convertible attics can be used for additional space.
• Inclined roofs are less restrictive and particularly easy to evacuate.

What are the Cons of slope roofs?

• Inclined roofs have more surface area than flat ones, hence resulting in more material cost, more labor hours and more energy and heat loss.
• Slope is always at greater risk of falling tiles, therefore, it is mandatory to securely fix everything that is tilted to the roof.

Roof sloping standards and regulations:

Like all aspects of construction, roof sloping has certain town planning regulations and standards that are to be observed essentially.

Rules regarding the degree of sloping, their width, number of slopes etc must be followed. For instance, certain roofing materials are required to be vigilantly calculated for a certain degree of inclination. e.g. maximum of 40% inclination can be done for a concrete roof. Similarly, 15% inclination is feasible for steel trough roof, 13-45% for zinc roof, etc.

WHAT IS COST ESTIMATION IN PROJECT MANAGEMENT AND THEIR TYPES?

PLU or Local Urban Plan of the municipality establishes the inclined roofs safety protocols i.e DTU for sloped roofs, which should be essentially practiced and respected.

There are 3 main DTUs on sloping roofs:

1. Distribution of vertical downspouts
2. Implementation of rainwater evacuation
3. Dimensions and calculation rules for pipelines

Once a client finalizes the inclined roof, the next step is to finalize the architecture of the sloped roof i.e single sloped, low slope, single roof, visible frame slope, etc.

Some of the commonly used slopes are:

Single sloped roof:

Mostly used in mountainous regions, these are best for easy evacuation of snow and preventing its accumulation.

2 or 4 sloped roofs:

Most commonly used inclined roofs, can be easily styled by adding rumps or brake lines, etc. The framework and the covering of a 2-sided roof are quite simple yet cost-effective. Also, the two slopes do not have to be identical and can be adjusted on different levels, if needed, aesthetically. Hence, this is the most commonly used slope.

On contrary, 4 sided roof has 4 slopes meeting at the top, giving it a classical cubic shape. Mostly classic architectures in cottages and mansions use multi roofing with turrets.

Pitched roof with core line:

This one uses a beam to raise the lower part, also known as rolled-up roofs.

Gable roof with break line:

Also known as “Mansard” or “Gambrel”, this roof consists of various inclinations making up different slopes. The upper part i.e Terrasson is joined to the lower part i.e Brisis, by means of a brake line junction.

Multiple roofs:

This one can range from very simple to very complicated, depending on the creativity of the architect and the limitation of the budget.

Tiles used on inclined roofs:

Tiles for the roofs are selected based on the client’s aesthetic choices and technical criteria. There are multiple options available, such as, terracotta tiles; which are weatherproof but fragile, slate tiles; these are heavy and expensive yet timeless, fiber cement; these are cheap but prone to moss and many more. Each tile shape has its own characters.

For example:

• Flat tiles can adapt to an inclination up to 35 ° and have greater density but they are a bit more fragile than others.
• Channel tiles can be used for 25 ° inclination but they need a supporting frame for their weight and a waterproofing reinforcement.
• Interlocking or mechanical tiles are suitable for anywhere between 25 °-60 ° slope but they are at greater risk of infiltration if their maintenance is neglected.
• Roman tiles, typically used in the south, are double interlocking and can adapt to 25-60 ° of inclination.

The type of installation, techniques used, and use of hooks and other supporting materials also depend on the slope of the roof.
