Metal shingle installation

Metal roofing materials are available in several styles that require different fastening applications, but are most commonly screwed to the roof framing or sheathing material, which in the case of installing over existing roofing material, should be. This is what it looks like when you install a steel shingle roof system over an existing asphalt shingle roof. Also, two layers of shingles weigh quite a bit. The shingles need to be offset in every space, so there are no valleys or blank spaces where a leak will start.

And the painting on metal roof today has the added ability of being able to reflect some of the heat back out of the house, too. Use metal roofing screws to attach the shingles in place. Be sure the larger edge is laid so that the small edge of the next panel will overlap it.

Even though steel is a galvanized metal, the roof still can rust, especially as close to the coast as your house is. Apply roofing cement to the back. In terms of whether or not you remove those shingles….

Because metal roofs are so light yet so strong, metal roofing panels can typically be easily installed over your existing asphalt roof shingles without the need to add structural reinforcement. This is more expensive but will also be higher quality. To install, line the valley with underlayment secured with roofing cement. Interlock hires sub-contractors and pay them very little which greatly affects quality to do their installs, while Classic may or may not hire subs. Last I know about 8 years ago, Classic had their own crew, and did not hire subs… but 8 years is a long time.

If it was my roof, I would hire a smaller owner-operated roofing company — not a national company like Interlock, or a local Classic dealer.

I live on B. I have been thinking of replacing the cedar shakes with metal shakes. I have seen on the internet some larger domes that have been covered with Reinke or PRS shakes.

Can you suggest a metal shake that could be used on this dome and that is available in Canada or could be imported from US. Thanks for any info Norm. I also really like Tamko steel shingles, and have installed them on my previous home, and will put them on my current home soon.

I would strongly advise to go with a flat er metal shingle and NOT shake. Your house will have a ton of cut edges and flat shingle will work a lot better when it comes to flashing the ends of each triangle section of your roof.

Raised edges of shakes, will make it extremely difficult to make the roof watertight. I understand you may like the look of shakes, but from practical approach, shingles in this case are much better. I have a question or six about gutters. We plan to install half-round gutters. We have exposed rafter-ends and no fascia on the eave, and would like to hang the gutters from straps nailed or screwed to the roof decking.

Would those straps go under the eave flashing? Lastly, should we even try to match colors, or just go with a plain galvanized finish on the gutters? Straps should go under roof starter eave flashing , but the design of the strap should allow for this.

You should have same contractor do both Roof and Gutters. You should be able to match color for Roof and Gutters. I know my supplier does this. The use metal coil from Englert fro both roof and gutters. Find a local metal roof fabricator.

We use Coastal Metal division of Beacon Sales. My husband is encouraging me to have our roof replaced because it looks too old and its shingles have come off already. I think we should hire a roofing contractor to do this for us since none of us have experience in replacing a roof. Thanks for a good review of metal roof shingles. We have an A-frame — so ALL roof!

What is your recommendation for an A-frame and steel shingles or stone-coated steel shingles? Hello, Thank you for this informative post.

The installer for Decra suggested leaving the actual asphalt shingles, adding a wooden structure and then the decra tiles. What do you think of leaving the actual asphalt shingles, which are 15 years old, thank you. Reinke Shakes LT shingles are guaranteed to never blow off. Made from. I am a big fan of metal shingles! Also, in my opinion, Reinke shake design is inferior in watertightness and flexibility as related to complexity of the roof to interlocking shingles, in large part because of corrugated design.

Reinke Shakes new LT shingles have more metal per square than any other aluminum shingle. They passed hurricane tests at 3 times the minimum. You can literally drive a semi truck on them without hurting them. Many customers brag on how beautiful they look. Asphalt shingles do not interlock. Check out the website and get the facts. It looks like Matterhorn was at least considering redesigning their flashing system at the time you were writing this.

Has this at all occurred? Even though we like the looks of the Mattherhorn better, your comments about the flashing system are pointing me towards Edco. Any thought? Many thanks! I appreciate your article. It actually pushed me in the direction of metal tile roofs. We live in an area that gets feet of snow in the winter, and metal has many advantages for that. Thanks for great question. So as far as Matterhorn goes, I did not really follow on the their flashing kit, but assume it is the same as before, becuase it was bough out by CertainTeed, which is primarily an asphalt shingles manufacturer, and does not have much expertise in metal.

See more here. These two factors create many possibilities for future leaks. However, since color-matching flat stock metal is available, you can have your roofer fabricate valley pan like the one in this picture.

First off, thank you so much for your work on this site. This is a great asset to a homeowner like me, looking to receive the value of a metal roof, but wanting to do it right. Here is the current installation PDF from the manufacturer:. The W-valley is reliant on caulk too much, as well as T-valley … but T will also collect all the leafs and debris from the roof. Again two-piece design make it more prone to installation error.

Although I had my supplier bend the V valleys for standing seam, as my break could not handle. I am thinking of going with a metal roof due to ice damning. I want excellent quality of product available. Please suggest other recommendations such wrap, insulation,special valley material. My house is sq feet with two great rooms with 26 ft high ridge beams. These sections attach to normal ranch style.

My problems are the large four valleys creat ice buildup and damning. Please suggest other recommendations such wrap, insulation, special valley material. My problems are the large four valleys create ice buildup and damning.

Best solution for Ice Dams is Standing Seam metal roof with concealed fasteners. However, I never had issues with metal shingles, and have personally installed many roofer with valleys, using steel and aluminum shingles from several manufacturers.

If you are not sure what W valley is, I can make a diagram. Here is what it looks like you will also see DeckArmor underlay in this pics :. Either metal roof product should solve your ice dams. However, I also recommend upgrading insulation in your home! This will reduce the root cause of ice dams. I have the same question as Ni Ra: Based on your experience, how does Kasselwood measure-up?

What are the Kasselwood advantages, disadvantages and material price range. The aluminum shingles are are based on an expired patents, so anyone can make them. In any case, my Kasselwood experience is very limited. Advantages of Kasselwood is the multi-tone paint, which you cannot get in Metalworks and a more pronounced texture. I would take Kesselwood over say Matterhorn, because of much better flashing design. I have an old slate roof on my Colonial Revival home in Western Massachusetts.

I need some repairs to the slate, fascia and porch roofs which are asphalt. I really like the look of the Permalock aluminum grey because it looks like slate. What do you think of Permalock aluminum product and being in Western Mass not on coast is it overkill?

I just want a good system that will be durable, no maintenance, and try to keep somewhat true to the historic look of slate. So, there are two things to consider as far as repairing slate VS new metal.

My suggestion — upload some pics of your current roof to Imgur and I will take a look, and guesstimate the shape of your slate. As far as Permalock vs stone coated tiles — definitely Permalock … i really am not a fan of stone coated steel, because they ALL have poor system design in my opinion. They are also pretty expensive compared to aluminum shingles. The are an excellent product, and the only negative thing about them — some manufacturers had bad paint batches….

I would also suggest steel shingles such as Tamko. When choosing metal shingles for my own home, I went with Tamko Slate singles, and most of the jobs i did for my customers in Eastern Mass were also Tamko.

Also since you are far from coast, you need not worry about salt air corrosion. See Costs in Your Area! Start Here - Enter your zip. Install Metal Shingles Roof: 32, projects Roof size: sq.

This will help keep any moisture from getting under the felt. In some situations, you will be required, or may choose to use a drip edge as gable trim. Once shingling is complete, only two steps remain. Be sure the larger edge is laid so that the small edge of the next panel will overlap it. Installing a metal roof yourself can save a significant amount of. The felt should be secured every six inches with nails or staples.

Attach your metal sheets to the framing. Apply the first course row of shingles over the starter course. The layers of felt should be overlapped by 1 inch as you work toward the roof ridge. Starting at the bottom or at one end of the roof lay the felt across the entire length, and then work your way to the top or center with over laying sheets and as you overlay use the nails to pin this down.

Make sure that each sheet overlaps the first one. Venting—the eaves to vent the roof, holes are cut in the old roof above the soffit, which pulls air through the soffit vents underneath.
