metal roofs

[jyl]

I’ve always liked the look of standing seam metal roofs. Anyone put these on your house? Pros, cons, how many kidneys to sell?

[Ayles]

I have one, got it installed 9 years ago. I cant think of any cons. It has beem maintenance free and we are super happy with it.

Loud during heavy rain unless its well insulated. I think? Only installed one so far in my many years of doing this. Never heard any feed back from the owner. They are happy with it, I suppose?

I think hail damage can potentially be a cosmetic concern and was told that firemen won’t go on them if that matters.

Matt Risinger did a video on this a couple weeks ago. He has a couple more if you go to his channel. Might be worth checking out

The proper material and thickness would be a concern. A traditional old school standing seam roof would have been galvanized steel in 22 gauge. There the ones you see on old barns that are 100 years old.

Many metal roofs today are very thin 29 gauge metal. Often they are painted or powdercoated aluminum.

The thicker the gauge the longer the life and more durable to weather conditions like hail or even falling objetcs like tree branches or a base ball.

We have one. Our house is 1/2 12:12 pitch and 1/2 5:12. It was ‘fun’ to install the 12:12 part when I built the house. I was basically repelling down the roof as I screwed into the rafter strapping. We did have a roof section get damaged in a big storm early on so one piece has faded a bit different. I notice it but I’m not sure anyone else does.

It is loud in a hail storm but otherwise great. In rain, it’s not any different from asphalt shingles.

Our home and two detached garages all have metal roofing . On the house we have metal installed over a single layer of shingles . This can be done IF the shingles are laying flat ( not curled ) AND a membrane designed for this purpose is installed over the shingles before the metal is installed. The membrane acts as a buffer for expansion/contraction between the metal and the shingles and is self sealing around the screws . We are on year four and no issues and very quiet in rain storms .

My man cave garage is a pole barn so rafters spaced about Evey 5' with perlons . The metal panels are screwed to the perlons. . The ceiling is insulated so it also is quiet in rain storms . Our parking garage is also an enclosed pole barn . Rafter/perlon construction but no ceiling or roof insulation . This is a loud echo chamber when it's raining hard but that's ok as it's just to park our two daily drivers in.

On all three buildings we have had zero issues to date . But we are only in year four or less so I wouldn't expect any issues this early . Years 20 and beyond will be more telling. But my expectations are these are the last roof's I will have in my lifetime 😁

^^^^ I need to replace my 30 year shingled roof soon (nary an issue... ever). I figure whatever material it is will be my last one...

Just replaced ours with architectural shingles. When you get into your 60’s, roof longevity becomes less important. Depressing in a way. But I still feel comfortable buying green bananas.

Eventually, everybody gets to where your hat will outlast you

I dig the tin roof, love shack baby

Friend of mine had a place with an old metal roof. He had this rattle can paint he put on it, 95% zinc he says, seemed a bit implausible to me, but that place was old when he got it and the roof always looked good. He should have sprayed that stuff on his Chevy with the Swiss cheese bed. He painted the roof using a truck with a lift bucket.

Metal roof is loud in a hail storm, I have seen them peeled off by wind, though if the wind is blowing that hard I am thinking what sort of roof you have would not matter

We had a metal roof installed last year and love it.

But there are a couple of issues to consider. One, if you live in an area that sees lots of snow (and depending on the pitch of your roof), there could be problems with sudden (and dangerous) releases of large snow-loads. Most metal roof manufacturers offer optional accessory vertical plates to help mitigate this.

Another possible issue, especially if your current roof system depends on gutters to help direct water flow away from vulnerable areas around your house (such as window wells and entryways), is that the installation of a metal roof can completely change the dynamics of water shedding, which can be further influenced by the possible necessity of the complete removal of any existing gutter system, which in turn might mean needing to do a bit of re-designing/changing the landscape around your house to facilitate appropriate and effective drainage based on your new roof.

Yet a third possible issue is related to your environment...especially if you live near salt water. On a recent trip to the Maine coast, my wife and I noticed that nobody who lived by the water had a metal roof...which makes perfect sense as salt (as we here all know) can wreak havoc on (even painted) metal.

I have a green metal roof on my house and garage.Going on 25 years now. The downside of metal is the expansion and contraction. The screws back out so every year before winter I get up there and tighten screws. Timing is huge because if it’s hot it will burn your butt and hands. If it’s damp you will slide right off. Oh, my rain gutters look like hell from getting torn off when the snow slides off the roof. Other then that they are great!!

We had one put in 23 years ago. Lots of tree debris here and the roof hasn’t noticed. I sweep and clean roof and gutters once a year.

Main parts of Roof are steeper than 1:3 and I can barely climb it when dry. Any water and pollen makes surface frictionless. Get extra d rings installed, can’t have too many.

It’s noisy in the rain, we were worried but love the sound.

One year a heavy wet snow released at once and crushed some stuff next to the house and tore off the gutter.

Most important part of metal roof is proper flashing, make sure it’s done right, overlapped well with a place for water to go.

Cost vs asphalt shingles?

[NYPorsche]

I had a Certainteed Matterhorn roof installed last year and couldn’t be happier. Not quite the standing seam you’re asking about but instead a series of panels that look like slate tile. It was was a $10k premium over 30 year shingles ($15k vs $25k) but that included full tear off of 3 layers including the original cedar shake, replacement with plywood and new gutters. But - it’s the last roof I’ll ever do and I’m never moving so good lord willing I’ve got another 50 years left living under it so the extra $ should be well worth it.

As far as rain noise - only minor above what the old shingle roof had and I work every day from the attic. I find the quiet pitter patter soothing at this point.

[OK-944]

interesting that those Matterhorn seams run horizontally - would help mitigate crashing snow loads I would think, and facilitate gentler water draining.

I put one on my roof winter of 2020. Aluminum to help with the corrosion here at the coast. It will outlive me. It was around $17K - double what an asphalt shingle roof would be, but I like the look and will get my money back should I ever sell.

You can get different colors but I wanted the most reflective to help with cooling. I have a remote thermometer in the attic and this metal roof certainly did help drop the temps a lot over the old asphalt shingle roof I had.

We did a complete tear off of the old stuff and replaced all the rotten or questionable wood pieces. Very good investment up front as this will be a big selling point, should I ever sell.

No issues whatsoever with noise from rains.

Entire job was done in 3 days!

I got an aluminium roof put on about 17 years ago. I'm 75 meters from breaking surf so the carbon steel pre-painted 25 year warranties didn't apply to me. the aluminium has been great. No corrosion and it's not painted.

Nice!

Did your electric bill go down, Bill?

Mine did.....
