From this guide, you will learn everything about metal roof installation so that you could make the right decisions concerning your next roofing project.
How Roofing Contractors Install Metal Roofing
In metal roofing installation, preparation and inspection come first. This will be taken by looking for damaged parts in the installed roof and making repairs on them to make the deck sound, free of rot and warping. When the base is ready, contractors will have to obtain necessary permits according to the local building codes for the smooth and lawful flow of the projects.
Next, an underlayment plays the role of a barrier to moisture. Along the edges of the roof, a drip edge is attached that serves to direct water away from the structure for improved drainage and reduced risk of damage.
The metal panels are installed, either directly to the roof deck or with clips for thermal movement. This creates a secure, interlocking surface that accommodates expansion and contraction. Flashing is installed at roof joints, chimneys, and vents to prevent leaks, ensuring watertight coverage. The ridge cap is added to the peak of the roof, providing a finished look and additional weather protection.
Finally, a careful check of all the components is conducted to ensure that everything was installed and aligned correctly. This final inspection ensures that the roof is secure and ready to provide decades of protection.
Types of metal roofing
Metal roofing comes in various styles and types, each offering distinct benefits and aesthetic appeal. Let’s look each of them:
Corrugated metal roof
This product has a wavy pattern with material made from aluminum, steel, or copper. These sheets are lightweight, low cost, and have high resistance to water shedding and the weather. However, some exposed fasteners will always cause leaks, hence useful for agricultural and industrial usage.
Standing Seam Metal Roofing
It offers advantages such as vertical panels with hidden fasteners, waterproof with an almost negligible maintenance requirement, and excellent for modern and traditional designs but rather costly in the upfront. However, its durability compensates for that cost.
Stone-Coated Metal Roofing
Steel panels painted with stone granules look like traditional shingles or tiles. Such roofings are tough, visually pleasing, and better in appearance than the regular materials but are costlier than the plain metal roofing models.
Zinc roofing
Zinc roofs have the natural development of protection patina over time and demonstrate substantial resistance to corrosion. Even though zinc roofing is in high demand due to extreme durability, very low maintenance, and appearance that stands out, it is expensive, less accessible, and less available.
Copper Roofing
Copper is very resistant to corrosion, but the aging process makes them a little bit green over time. They are durable as well as aesthetically pleasing, however, they are rather expensive and thereby less suitable for homeowners on a budge.
Aluminum Roofing
Aluminum roofs are lightweight, resistant to corrosion, and readily available along the coastal areas. These are energy-efficient making them ideal for eco-sensitive buyers. However, compared to steel, aluminum roofing is higher in price, which may be unaffordable by some homeowners.
Metal Roofing Installation Cost
Prices for the installation of metal roofs in New York depend on such factors as the type of metal used, size of the roof, and intricacy of the installation. The average price ranges between $11,200 and $61,300 or between $11.30 and $17.50 per square foot. Based on this amount, the price of the average 1,500-square-foot standing seam roof would run at approximately $21,550.
Materials have a range, with aluminum going for anywhere from $469 to $1,030 per square, whereas copper goes from $1,465 to $2,570 per square. Material labor takes about 40 to 50 percent of the entire job price, taking about $9,231 for the regular size house. While the upfront investment is greater than asphalt shingles, metal roofs save money in longevity, as the life span is between 20 to 50 years with proper maintenance.
Metal Roof Installation Time Frames
The time required to install a metal roof depends on the size of the roof, the design complexity, weather conditions, and availability of the contractor. It takes one to three days to install for a medium-sized house. For a small roof, if the weather is pleasant and there is a large crew on the project, then it can be completed within one day. If it is an intricate layout or bigger roof, then it will consume more days. Added factors such as building height, accessibility, and possible weather disruptions could also affect the time; thus, the homeowners should plan with a plus or minus to accommodate the sudden delay.
Installing Metal Roof Over Existing Roof
One of the most attractive features of metal roofing is just how versatile it can be for installation. Many times, metal roofing can be installed directly over existing roofing materials, which reduces waste and installation costs. However, this should be done with great care by a professional who can ensure the structure of the existing roof will support the additional weight and that proper ventilation is maintained.
Metal Roof over Shingles
For metal roofing over asphalt shingles, contractors usually take a special underlayment and may install vertical furring strips to create an air gap. This approach avoids moisture trapped between the old and new roofing and provides better insulation and ventilation.
Metal Roofing for Sheds
Sheds are a great opportunity for metal roofing, as their roof designs are usually very simple. In such cases, corrugated metal panels are often the cheapest and easiest to install. The installation process is quite smooth, with most shed roofs being completed in a few hours.
Metal Roof Over Composite Roofing
Similar to installation over shingles, metal roofing can be installed over composite roofing materials. This is very similar to installing over shingles, except that more caution will be taken in assessing the condition of the existing roof and possibly adding additional support structures to accommodate proper installation.
Metal Roof Installation on Flat Roof
Flat roofs require special metal roofing systems that offer advanced water resistance. Standing seam or flat roof-designed metal panels are installed, with particular attention given to the sealing and waterproofing technique.
Accessories for Metal Roofs
Other important accessories involved with installing a metal roof are underlayment, flashing, fasteners, and ridge caps, all of which are quite important for the durability and performance of the roof.
Underlayment
The underlayment is a very important layer between the roof deck and the metal panels, providing the necessary barrier for infiltration. Underlayment is also about $4 to $5.50 a square foot. That said, for 1,700 square feet, you may get a total of $8,075 installed. A breathable synthetic underlayment is suggested in many ways since it offers good protection and performance.
Flashing
Flashing redirects water from roof joints, edges, chimneys, and vents. Depending on the application, materials range from aluminum to galvanized steel at about $1 to $3 a linear foot. Installation costs vary by roof complexity but generally add in the range of $1,000 to $2,000 to the overall project expense.
Fasteners
Fasteners attach the metal panels to the roof and are one of the most critical components that will ensure the stability of the roof. The prices of these fasteners range from $0.10 to $0.50 each, and several hundreds of them are required for an average-sized roof. Overall, the total cost of fasteners will lie between $200 and $500, depending on the size and design of the roof.
Ridge Caps
The ridge caps go onto the peak of the roof to seal the top edge, adding a touch to the roof for aesthetics and additional water resistance. They come at an average price of $3 to $5 per linear foot. For a 40-foot length of the ridge on the roof, it should cost between $120 and $200 for the homeowner.
Additional Accessories
Other necessary components may include a gutter system and ventilation installation. Gutters are vital so that water does not run across the foundation of the house, and their prices fluctuate between $5 and $15 per linear foot. Then there is ventilation, which takes care of the airflow appropriately. The cost of ventilation installation fluctuates between $300-$800, depending on both the type and complexity.
