Lightweight Design Relieves Pressure On Homes Structure

Can You Put a Metal Roof Over a Shingle Roof?

If your home is older or isnt built to withstand such heavy weight on the roof, it can be detrimental to your homes integrity and foundation. Luckily, metal roofs are incredibly lightweight compared to other roofing materials. For example, some roofing materials such as slate, clay, or even premium asphalt shingles can weigh 2 to 6 pounds per square foot, while metal roofing might weigh around 1.5 lbs.

How Much Will Your New Flat Roof Cost

Too many factors go into the cost of a flat roof replacement or any roof replacement to give you an exact price. However, I can give you a general idea of how much your new flat roof will cost.

A good rule of thumb is to budget between around $14.00-$17.00 per square foot for a smaller membrane flat roof and around $12.00 per square foot on slightly larger projects. Be aware, if you use insulation thats thick enough to insulate the entire structure, it will cost more than just using fabric insulation and gluing the membrane to it.

On the other hand, a 24 gauge steel standing seam metal flat roof will cost around $15.00 per square foot. This number could be more or less depending on the size of your flat roof, the number of penetrations, the roofing contractor you hire, and other factors.

Flat Roofs Create Space That Can Be Used In Many Ways

One thing that makes flat roofs unique is that they add usable space to a property. They can be transformed into gardens, patios, or green roofs. Installing solar panels on a flat roof is a simple process. Best of all, the panels are much harder to see on roofs like these, meaning that they wont detract from the look of the property.

Planning for applications like these should be done early on in the design process. That way, special features such as guardrails can be added. The roofing materials can also be chosen based on their ability to stand up to foot traffic and to bear extra weight. Depending on the local requirements for Anderson or Oconee County, a permit may also need to be obtained before installing features like these. In most cases, however, it is worth it since it creates extra space for you and your family to enjoy.

Shingled Mobile Home Roof Overs

A real shingle roof for mobile homes is absolutely possible for most models. They can have a higher pitch or gables too. Shingle roof overs are also installed right over your existing roof, as long as you have not already had a roof over previously.

The subject of whether its a good idea to add a second layer of shingles is much debated in the roofing industry. Be sure to get an experts opinion on your home before you make a decision. There seems to be a split in opinion on layering the new shingles over the old. Some roofing experts say you can do on manufactured homes that have 2×4 studs 12-16 OC and roof trusses that are 16 OC or less. Others roofing experts have told me they wont do it on any manufactured home.

If youre set on a shingle roof you come in a few different options and styles for roof overs, as well as several different colors and textures.

The main benefit of a shingle roof is the appearance. Shingles can dramatically improve the curb appeal of your property. Installing shingles is typically more costly than a TPO or metal roof but can improve the value a little more so you may recoup the costs.

Disadvantages Of Rib Installation

  • Negatively impacts the sheer strength of the panels: Placing screws on the rib leaves a 5/8 to ¾ -inch gap between the underside of the high rib and the wood framing below. The screw can flex within this space, reducing the sheer load-carrying capacity of the sheathing system.
  • Risk of leaks around screw cranks: The flexing of screws in the gap between the rib and the wood framing below allows steel panels to move slightly under wind or seismic loads. This can result in slots in the steel around the screw shanks over time, potentially causing leaks.
  • Weaker roofing attachment: The fact about three-quarters of the screw length goes to waste means you dont get the strongest roof attachment. The screws can more easily pull out during strong winds and storms.
  • Higher risk of damaging the rib, and roof: Finally, theres a higher risk of damaging the ribs and even the roof if you screw on the rib. Why? Because theres no support below the rib. The space under the rib means any hint of over-tightening can collapse the rib. This usually forces contractors to pre-drill the holes before screwing, which only prolongs time spent on the project.
