If man-made roofing slate is made from some type of polymer or polypropylene blend its a plastic slate tile.

The pricing table for plastic roof slate prices looks very different as you dont buy plastic slate in single slate quantities.


Stone Slate Roof Cost

One option for your roof is using stone slate which, provided its well looked after, can last more than a hundred years. The average stone slate roof cost is around £40 to £60 per m2.

The cost of your stone slate roof will depend on where the slate is from, whether its new or reclaimed, and where you live.

Do They Specialize In Slate Roofing

When you have a slate roof installed or maintained, the work should only be done by roofing professionals with extensive backgrounds in the application of slate. This qualifier is crucial, considering the special handling required for slate shingles. A roofer with little or no knowledge of slate is liable to make mistakes during an installation that could lead to costly problems soon after completion.

A common mistake among roofers is to employ the same application methods that work for other types of roofing materials. For starters, the roofer might break tiles while walking across the roof during the installation process. Even worse, the roofer might leave the fasteners exposed to rain and snow.

One thing a roofer should never do is coat slate shingles. There is no reason for slate to have any coating, as the stone is, by nature, resistant to fire, rain, snow, hail and wind. Roofers who leave nails exposed face-nailing, as the problem is called have been known to cover the imperfection with tar when performing repair work. In cases like these, tar often winds up brushed along the shingles. When covered with tar or any other coat, the surface of the slate loses its aesthetic luster.

    Slate Roof Repair – How to replace a slate & broken slates

    Poor quality slates are less resistant to pollutants present in the air, and due to the chemical makeup of natural slates, they are prone to soften and degrade over time.

    S1 No action is needed

    S2 The quarry must split the slates 5% thicker than standard

    S3 Slates are at least 8mm in thickness.

    Can You Install Slate Roofing Diy

    Unless you are an experienced roofing professional, you should not attempt to DIY any roofing project. Roofing is a complicated process that requires specialized tools and experience. Plus, slate roofing is tricky even for roofers because its so heavy.

    Trust us on this one: You wont save any money by installing your own roof. Youll probably spend even more money fixing the damage you cause to your home or yourself.

    So Why Are Slate Roofing Tiles So Expensive There Are A Few Reasons

    • Roofing Slate tiles last longer than any other type of roof One of the reasons that slate is so expensive is that it is extremely durable and long-lived. A typical slate roof has a 100 year or longer lifespan, and usually does not require any roof repairs. As one of the most durable roofing materials on the market, slate tiles command a premium in terms of price per square metres of material.
    • Slate tiles are hand-selected and hewn Slate tiles are extracted from mines in Wales, Spain, and Canada, among other areas. They must be extracted and process by hand by specialized miners and artisans which makes them more expensive to produce.
    • Being extremely heavy and costly to transport Slate is very dense, compared to other materials like asphalt shingles, cedar shakes, and metal roofing. This means that the cost of transporting slate is quite high, compared to other roofing materials.
    • It takes longer to install Slate and it is more difficult Slate takes longer to install, due to its unique characteristics and weight. While a worker may lay up to 10 squares of cedar tiles or asphalt shingles per day, it may take a full day to lay just one square of slate tiles. In addition, securing slate properly requires years of experience for the best results, a master slater must oversee the operation. Again, this means that it takes longer for slate to be installed increasing overall project costs.

    Is It Ok To Walk On A Slate Roof


    Under no circumstances should you walk on your slate roof, as youd be causing damage to your roofing system and thus signing up for constant repairs.

    Insulating A Slate Roof: An Overview

    Spray foam used to insulate your roof will almost always be used in the same way. It is sprayed directly onto the underside of your roof structure from the inside. Layers of foam are applied between the rafters and then either left as it is or covered with plasterboard.

    The main concern people have with applying spray foam in this way to a slate roof is that many of these roofs are constructed with no barrier between the slate and the inside of the loft.

    In other words, the spray foam adheres to the slate directly. As you might expect, there are pros and cons of this approach:

    Calculating The Size Of A Roof

    One important thing to keep in mind when estimating roof tiling cost is the area of your roof, which isn’t the same as the area of your house. This is because the roof pitch can make a difference to the number of tiles needed to cover a roof. A steeper pitch takes up a larger area than a gentle pitch, and if there are several different pitches, it could cost more.

    For example, a home of 100 square metres will need approximately 112 square metres of roof tiles. If it has a steeper pitch or a more complex shape, more tiles will be needed.

    The best way to determine how many square metres of tiles you need is to look at a drawing of your house and measure the roof area. If you don’t have drawings of your house, a roofing contractor can accurately tell you how many square metres of tiles you need based on their previous experience.

    Tile Roof Restoration – What to look for on your tiled roof

    • The draining and ventilation must comply with building regulation standards
    • The roof must be fire-resistant
    • Have sufficient weatherproofing

    English slate now restricted to Westmorland and Burlington slate, both of which have been quarried from within the Lake District since the 17th century.

    Offering a lifetime measured in the hundreds of years, Westmorland and Burlington slates are both incredibly hard-wearing and strikingly attractive. Westmorland slate has a distinctive blue-green appearance, while Burlington slate is smoky grey.

    For new Westmorland, expect to pay around £200 per square meter, for reclaimed this price drops to around £40! Because of the complexities in installing this prestige roofing material, always make room in your budget for using experienced roofers who have worked with it in the past.
