Prices and materials for re-roofing
Are you looking to know the costs for replacing your roof? You are in the right place!
When renovation work is no longer enough to maintain your roof in perfect condition, a repair is required. You must then opt for a quality structure made of durable materials that will be put in place by a specialist in the field. At the budget level, you need to take into account prices and related materials. Overview.
Redo your roof: know the different types of roofs
Shingle roof
Recent models contain only inorganic substances. Those offered on the market are very varied and you will have a wide choice of colors and styles.
Weight is an important criterion in determining the durability of shingle roofing. This type of coating typically lasts 15 to 20 years, but heavier models can last up to 30 years. In all cases, a distinction must be made between roofs made of asphalt shingles and wooden shingles.
If you are considering redoing your asphalt shingle roof, it is important to provide protection against the sun's rays that could cause cracks. It is therefore essential to position the gravel correctly on the membrane.
On the other hand, your asphalt shingle roof is more resistant to humidity and does not require careful maintenance. On the other hand, it is necessary to apply a coat of tint regularly to maintain it. However, it is more resistant.
Slate roof
Composed of natural stones bringing a touch of elegance to your home, it is frequently used for roof repair in Montreal. This type of covering has the advantage of being non-combustible and impermeable. Redoing a slate tile roof guarantees the longevity of your structure up to 75 — 150 years.
These models are generally heavy and fragile and require periodic maintenance. To redo a slate roof, you must always take into account its fragility, as it risks breaking under the weight of a man.
Sheet metal roofing
It may have a wavy or bent appearance. You won't have much difficulty maintaining it. The Tinsmith in Montreal generally prefers this model over a shingle roof, because steel can handle snow more than asphalt. In addition, sheet metal is recyclable.
On the other hand, this model is less resistant to salt air corrosion and to electrolysis. You should also repaint it with a PVC, polyester or polyurethane-based dye to increase its lifespan beyond half a century. In terms of comfort, you should expect a more or less pronounced noise during the rain.
Flat roof
This single-layer or multi-layer membrane coating may be made of asphalt or elastomers. It is sometimes used to redo the roof for a house located in an urban setting.
This type of roof can be made of wood, metal, or concrete. In all cases, the device must ensure perfect tightness to avoid the infiltration of rainwater.
Elastomeric roof
THEroof inspection in Montreal sometimes recommends elastomer roofing because of its great weather resistance. In addition, it can be installed at any time of the year.
Since its composition is made of asphalt, it is therefore not recyclable. The repair of an elastomer roof must be entrusted to a specialist to avoid the risk of fire.
Green roof
If you are going to add a roof terrace, it is more beneficial to cover your house with a green roof. There are extensive models, i.e. without a garden and intensive models, with a garden. Thus, you can make small plantings on your intensive green roof.
Among other things, it allows you to leave a good ecological footprint. It is distinguished by its aesthetic side, but it is especially advantageous because of its great resistance to wind, humidity and snow. With proper maintenance, a green roof can last up to 30 years.
The materials used for each type of roof
Asphalt or wood for shingle roofing
The shingle roof contains either asphalt or wood. Redoing an asphalt shingle roof guarantees the resistance of your roof to humidity. However, they must be replaced regularly to keep the roof in good condition. Moreover, these materials provide a practical installation.
Wood shingles look like floors that are available in several species. They are extra waterproof, but are less recommended for fire prevention. Smoothed wood shingles need to be repainted every 5 years, and rough shingles every 15 years.
Metal, aluminum or copper for sheet metal roofing
Roofing sheet is made of metal, aluminum, or copper. This material does not rust in the weather and has an unlimited lifespan with good maintenance. It has the advantage of being recyclable. For aluminum sheet metal, recycling can even be 100% done.
This sheet of iron can be more or less thick and its tightness determines its quality. As for its color and flexibility, you are free to choose the ones that suit you from a multitude of models. Sheet metal roofing is non-combustible and often quite light.
Gravel, TPO or EPDM for flat roofs
Materials composed of a multi-layer asphalt membrane or gravel can be used for a flat roof. The liquid asphalt is mixed with felt and the whole thing is then covered with gravel. This type of material is more resistant to the sun than tar, formerly used in flat roofs. However, it is still possible for cracks to occur over time.
There is also a flat roof made from polyolefin thermoplastics or TPO based on vinyl. The other flat models contain synthetic rubber inside an ethylene-propylene-diene terpolymer or EPDM. These materials are durable, lightweight and do not retain mold. They are more resistant to all weather conditions.
Elastomer roof
For this type of roof, a material composed of a double modified bitumen membrane is used. Roofers prefer to install it because of its more consistent finish. The elastomer can also be used as an underlay for an asphalt shingle or as a cover for a flat roof because of its long lifespan. This material is also practical for redoing the roof of a garage.
Environmentally friendly material
The green roof is made from ecological material that requires great maintenance. With this type of coating, the house is warmed naturally and the roof insulation is increased tenfold. You are therefore protected from pollution and sometimes annoying external noises.
Elastomer roof and green roof
If you want to redo the roof of your garage, the price of the elastomeric membrane required varies between about $8.50 to $14 per square foot. The cost to redo a roof can easily exceed $20,000 for an area in excess of 1,500 square feet. A house decorated with this type of coating would undoubtedly be original, but you will have to pay the price to take advantage of it.
For a green roof, the estimated price of an extensive model is 15 to 25$ per square foot, while an intensive model is offered at around 40$ per square foot. Note that the cost of the installation involves several elements, namely: the installation of the membranes, the drainage and rain retention system, not to mention the plants.
The cost of a roof repair
Expenses include the price of the roof and the cost of labor for the renovation. A professional roofer can draw up an estimate after examining the condition of the premises.
The price of a shingle roof
A shingle roof costs around $3 to $5 per square foot. The price to redo an asphalt shingle roof varies according to the surface to be covered and the complexity of the work.
For a typical bungalow with a sloped roof, you need to plan for $4,000 to $6,000 to redo your asphalt shingle roof. For a two-storey house, the work costs between $5,000 and $7,000. And if you want to reroof your luxury home, plan between $9,000 and $17,500.
The budget for redoing a slate roof
The cost to redo a slate roof is high. Vendors offer a square foot of roof for nearly $22.5 minimum and the price can go up to around $40. To redo a slate tile roof, your budget varies from $20,000 to $35,000 for a bungalow, $25,000 to 40,000 for a two-storey house and about $40,000 to $60,000 for an architect's house.
Sheet metal roof and flat roof
The tin roof costs between $12.5 and $15 per square foot, but it is expensive to install. The price to redo a sheet metal roof is in fact around $15,000 to $25,000 for a bungalow. It can even go up to nearly $30,000 for a two-storey house. With a house with a particular structure, the renovation will cost you between 30,000 and 60,000$ approximately.
The joint of the flat roof is very delicate and explains the high cost of its installation. Add to that the roof price of between $8 and $10 per square foot. The price to redo a flat roof is therefore evaluated according to the area to be covered and the complexity of the task.
