Buying a Metal Roof? Top 9 Things to Consider

[@jeffreyallen3777]

Interesting comments reguarding "oil canning". I am a small volume metal roof installer and have been installing double locked standing seam for many years, I never used stiffening ribs as I always liked the aesthetics of a flat panel better, for several reasons. I have installed some roofs that though mechanically sound , had to my eye a lot of oil canning.As you commented , if the panel is flat on the bench the cause of moderate to severe oil canning will nearly always be the stresses caused by an irregular roof deck.This is common on many older, pre-truss structures. Over the years though, I can't recall more than 1 or 2 customers bringing up the issue. I think a small amount of oil canning goes with the medium and is lost in the basic beauty of a carefully installed standing seam roof. To me the quality is a thoughtfull layout and carefull detailling.I have over the years installed several copper standing seam roofs-then you get to really talk about oil canning.Thanks for a very informative video.

Thanks for sharing! You're right; oil canning is definitely an inherent part of metal. There are ways to minimize it, but when installing for residential it's important that the homeowner has expectations for whatever panel type they choose. Glad you enjoyed the video! -Thad

[@andyzehner3347]

I found this really useful, and have now decided to go ahead with a local contractor. There is a mistake at 3:36. You say, "A shingled roof is typically the least inexpensive thing that you can get."

[@TheMetalRoofingChannel]

You're right, it should be "least expensive". Good catch, thanks Andy! - Thad

What is a cool roof, is that the type of paint on the roof. Getting ready to do a metal roof in Arizona.

Just had Hy Grade Roofing install a metal roof at my house. Worst decision I could have made. They promised to install the roof in 4-6 weeks, of course they were late. When they finally showed up without the proper equipment and damaged my property. They are really proud of the “Quality Audit” that they do, but of course they won’t give you a copy of the audit…lol BTW -the “Quality Audit” they did at my house consisted of 2 guys coming over to pickup the leftover junk they left at my house for a month. They never even went up on the roof! Save your money use someone else!

[@petergromlich6529]

What does that have to do with this video?

[@mikeez5455]

One thing I don't understand is why is standing seam twice as much as screw down? Both take about the same time to install.

Several questions: Can metal roofing be used for houses with flat roofs, as is common here in Arizona? I am interested in metal roofing for fire resistance. Also, with regard to the heat here in the Southwest, does one need to use significant insulation and other methods to prevent the transfer of heat to the home? Lastly, with regard to placement of Solar Panels - would metal roofing prohibit the use of Solar due to high heat radiated by the roof or due to attachment difficulties or complexities? Thank you.

[@TheMetalRoofingChannel]

Hello! Thanks for the questions! We don’t recommend metal roofing on completely flat roofs. There has to be some type of slope in order for water to shed. The minimum slope will depend on the panel profile and installation technique. The lowest sloped panel Sheffield Metals offers is the SMI 2.0 MS which can go as low as a 0.5/12 with sealant installed in the seams. When it comes to insulation, it is going to depend on the specifics of your project. Rigid insulation can be installed between the roof panel and the decking but it might not be necessary due to the design of your home and the use of the cool roofing pigments in the panels paint system that will reflect a lot of the sun's energy. Beyond insulation, there are methods to reduce heat using products that raise panels off the roof deck and allow ventilation between the underside of the panel and the roof deck such as Sharkskin Ventilated Mat. Additionally, there are products such as Sharkskin Radiant that provide additional insulation by reflecting more heat transfer than that of a system without. While these items will provide energy savings, they will also drive the pricing of a metal roof installation up. I would recommend speaking with a qualified installation contractor on the specifics of your building. Lastly, attaching solar panels to metal roof is quite common. There are brackets/clamps designed specifically for the attachment of solar panels to a standing seam metal panel. I hope this answers everything for you! -Thad

My new construction home is a 12/12 pitch cape cod with 3 dormers. I'm thinking an exposed system will work fine. Any suggestions? Thanks.

[@TheMetalRoofingChannel]

Hello! There are some key differences between exposed fastener and standing seam, including material thickness, paint finish, and longevity. We did release a video on this topic which you can check out here: bit.ly/EF-vs-SSMR-revisited If you have any specific questions based on your location, budget, or anything else after you check out that video, let me know and I can get our tech department involved to help further. Thanks for the question! -Thad

Question, I just got a brand new shingle roof from hurricane Imra (September of 2018), just this past week a hail storm came through and wrecked my neighborhood. My insurance adjuster said my shingles have hail damage and I need a new roof. Could I do a standing seam metal over my existing shingles. All my decking is in good shape.

[@TheMetalRoofingChannel]

Hello! Having your roof deck in good shape is an important factor when considering this. We talk about some additional factors about metal roofing over shingles in this video here: bit.ly/metal-over-shingle-video Thanks for the comment! -Thad

[@trinifirst6702]

I plan to install a metal roof myself. You don't seem to encourage this, perhaps to drive people to contractors. I've done this in the Caribbean before, where there are not strict building codes but houses survive well due to common-sense practices. There are many KZbin videos which will guide you though, and once you adhere to the building codes you should have no problems. In the Caribbean no underlayment is used. however for Florida, I ask is "tar paper" adequate as an underlayment?

[@TheMetalRoofingChannel]

Hello! Our main concern when suggesting people go with a contractor is to help make sure a valuable product like metal roofing is installed properly and safely. As you said, adhere to building codes if you decide to install your roof yourself. In answer to your question, we have an article about synthetic underlayment vs. felt paper that you can check out here: bit.ly/synthetic-vs-felt-underlayment Thanks for the comment! -Thad

[@mfblowfish4671]

A lot of people don’t think they have to hem the panel. Also it not exactly easy to get more if you screw up your order. I paid $400 per 100 sqft materials cost. That was for 24 ga snaplock panels, with a PVDF coating. That did not include the dry in/ underlayment. Once the panels are one you can not get them off easy and since the material is so high on cost most people would be better off hiring a professional to install. It’s pretty easy thou unless you have valleys, skylights, chimneys, etc..... also hem the panel to the drip edge and use the right accessories

[@JCcanU]

yes , frost states , frost will thaw i use 30# tar paper. steel when frost it will rain under side when the sun hits it .

I've done standing seam now for 7 years. Coming from a carpenter background there definitely is an art to it. With the different flashing and cap.

I've been reading about new configurations in "Corrugated" steel roofing. Is this type of material appropriate for mid to high-end residential applications? Is corrugated appropriate for low slope (3 in 12) portions of a residential application? Thanks, Tim Gaddo

[@TheMetalRoofingChannel]

Hey Tim! We just released a Q&A episode today about exposed fastener metal roofing that will give you some good information on the topic. You can check it out here: kzbin.info/www/bejne/ooeboH-YZr5qldE To answer your question, typically a 3/12 slope would be the minimum slope that a corrugated panel could be installed on but you should always verify this with the manufacturer. From our experience, standing seam roof systems are a more popular choice for higher end residential projects but nothings says that a corrugated metal roof could not be used. Please keep in mind that an exposed fastener roof system will require more maintenance throughout its life cycle and the owner should have a maintenance schedule or check list. You should keep other factors in mind as well, such as available engineering, paint systems and their life cycles, and HOA or municipality rules and regulations. For installations, always check with the manufacturer of the corrugate system. Depending on which type of corrugate, some require a double-lap for the roof installation and some require a single-lap for walls. The manufacturer will also dictate what should be used in terms of sealants, tapes and closures. Thanks for your question Tim! -Thad

[@briangc1972]

I have an exposed fastener metal roof that is 9 years old. It is a 2.5/12 pitch and hasn't ever leaked. I just installed another one on an addition that is 1.5/12 pitch and we just had our wettest winter (in the past 30 years) and no leaks on it either. Common sense rules when installing. Don't over tighten/ strip fasteners. When in doubt, caulk it with poly butyl caulk.

[@jasonarmstrong4556]

Why is standing seam so much more expensive than face nailed? They're both metal and they both run through a roller.

[@TheMetalRoofingChannel]

Hello! The price difference comes from several factors. Exposed fastener metal roofs are generally a lighter gauge metal, often use a lower quality paint system, and take less time/labor to install than standing seam.

I will be installing galvalume metal roof on my new house. Should I request the installing company to place 1x4 over the underlayment and below the metal roof? I figured by fastening the clips to 1x4 that are fasten to the rafters is more reliable than just fastening the standing seam clips to the the OSB... your thoughts? thanks.

[@TheMetalRoofingChannel]

I would check with the company and see what type of engineering they are using for the installation and see if it supports using 1x4’s. If a system is tested, it takes the guesswork out of installation requirements. Thanks for the question! -Thad

[@robnation2475]

Go straight to the deck and use synthetic underlayment. Snap-ridge hidden fastener panels are the way to go. There are many different brands that are coated the same way (zinc paint on steel)

[@MeMe-ur6bg]

This is what the Director at the Canadian Roofing Association (CRCA) has to say about Hy-Grade: "I will say that I have researched this company - Hy-Grade Roofing - and did not take me long to find several complaints and bad reviews with the BBB (Better Business Bureau). These types of complaints would have been enough for me to pass on this contractor. I see many issues and complaints related to the many ‘Metal Roofing Companies’ who promise the world to the customer, then don’t follow through when it’s time to enforce the warranty or get issues rectified..." Not even the CRCA would use you as a contractor. I invite all potential customer to contact the CRCA before signing with Hy-grade!

[@kylekarwowski2642]

I watch the Pure Living for Life channel and I enjoy it. I give the guy credit for taking on so many different jobs. However, that is not what I would call a true standing seam that he is installing. It is a snap-lock standing seam not a mechanical field lock, which is more watertight and more labor intensive. Not bashing snap-locks, I have done quite a few before I got into mechanical lock. I just think it is an important distinction to make.

Came here wondering difference be steel vs aluminum...left dissapointed

[@TheMetalRoofingChannel]

Sorry we didn't answer you question in this video! There are several notable differences between the two. Aluminum is often more expensive than a steel substrate. It is also lighter than steel, and has better corrosion resistance if you're near a coastline. We recommend using aluminum if you're within 1,500 feet of a coast.
