What is a Tin Roof?
The two primary types of tin roofs homeowners install are standing seam metal roofs and the flat-lock tin roof. Both are attached to wood sheathing using blind-nailed clips. The flat-locked tin roof requires superior skill (i.e. not a DIY project) to form the pieces and more importantly, soldering the seams between all the interlocking pieces of metal.
Tin roofing is actually rolled steel, coated with tin. The tin is chemically bonded to the steel in a plating process where the steel is heated quite hot and saturated with molten tin. The steel and tin molecules that are rapidly vibrating because of the heat, interlock and bond permanently to one another. This process makes your tin roof durable and resistant to cracking. If your tin roof is properly installed and maintained it can last for up to 40 years! Tin roofing is also eco-friendly as it is usually made from 30 to 60 percent recycled materials.
Pros and Cons of Tin Roofs
Metal roofing is a far greater investment than an asphalt roof. Homeowners should consider the fact that the life of a tin roof is decades longer than other roofing material types— and that it can add value to your home. A metal roof can be an affordable option if you want to install a cheaper metal roof material.
- Lasts up to 40 years or more
- Provides a great return on investment and can increase your home's value
- Resistant to harsh weather like extreme rain and snow
- Can be noisy if attic is not insulated
- Can become dented during hail storms
- More expensive than many other roof types
Before investing in a new metal roof, you may have concerns about the potential for rust, noise from rain and wind, and denting, but modern engineering addresses these concerns.
You do have to properly insulate your attic to prevent your roof from creating too much noise, but this is sound advice regardless of the type of roof you choose to install. Additionally, with most textured roofs, minor denting if it occurs is not easily visible. Finally, some believe that metal roofing will increase your likelihood of a lightning strike. While metal does conduct electricity, electricity is not drawn to it. In fact, because metal roofing is fire resistant if your home is struck by lightning, your risk of fire is actually decreased.
Tin Roof Pricing
The average roofing installation price for a tin roof costs anywhere between $9,000 to $45,000 depending on the slope, pitch, and size of your roof. You can expect to pay $3 to $15 per sq. foot or $300 to $1,500 per square installed on a standard sized single story home. Roof replacement costs will vary depending on local roof contractor’s pricing. View your potential roof installation savings with local contractors below.
Tin Roofing Repair
Tin roofs are typically simple to repair and easy to maintain. For the longest life possible, gently scrub your roof once or twice per year and keep it clear of debris. Re-apply the protective coating every 5 to 7 years to make sure it stays looking sharp and resists the elements.
You can find a reliable local roof repair contractor to help with this project. Often seen in black or red, you can hire a paint company to tint an exterior metal paint to make your roof any color you desire. If you do scratch your roof, the scratched area can be wiped down with mineral spirits, and touch up paint can be applied with a paintbrush. Tiny areas of peeling paint and minor surface corrosion can be easily repaired, even if you are not the handiest person.
