How to Install Roof: Best Roofing Practices

Hey guys this is the best roof practices, the meet you here for roofing insights actually for one of our jobs for story proofing today we decided to show you.

What it takes to install shingles in 2018 in the last 10 years roofing industry evolved a lot there’s a lot of things have changed and we see there’s a lot of outdated information on different websites a lot of guys still installing the roofs old-school so we want to show the way what does it take to install the good quality roof in 2020.

Lest Start Discussion About Best Roofing Practices


So the first thing guys, you always want to start with a complete tear-off of existing systems I see in a lot of parts of the country in Canada as well a lot of roofers simply going over the shingles unfortunately it’s not recommended by almost any manufacturer and also it’s illegal it’s against the code and a lot of CDs.

So what’s happening is a lot of roofers to save the cost for the homeowners they simply go on over existing the problem with that is they cannot inspect the right of the plywood underneath they cannot see the spacing they cannot see ventilation they cannot see the plywood OSB or how that roof system was built and for those reasons.

Nobody is recommending that and manufacturer sides also serious will not close the premise if they don’t see what’s underneath to install good quality roofing system you do want to completely remove it to the bare deck and we highly recommend.

It’s pretty much the only way to do the job right it’s a hundred percent to remove all the materials that are on the roof right now. I would like to say that please follow my Best Roofing Practices guide and this is also fiberglass roof repair so you should also follow for fiberglass roof.

Especially if the product is very old you’re talking about 20 to 30-year-old systems that have been there who knows what’s underneath you want to check it all out.

Second, once you remove everything you want to make sure you inspect everything you replace whether it’s always been or whether you’re doing boards you want to make sure there’s not white spacing in all houses that have been built in 40s and 50s we see a lot of homes with the really big gaps have Finch 5/8 gaps that’s a big problem as well.

Because when you install asphalt shingles and your nails will not go through the wood it will go through those holes and your roof will fly away with the winds because there are no nails. That’s you know in the wood pretty much so what’s happening is I see a lot of roofers still gonna go through and install and then when the big wind comes in it literally can lift ah because there are not enough nails in the wood so that’s different big no-no as well so you want to read deck entire house like that here in Glasgow where we work we would say every year five-seven percent of our jobs getting fully redact.

Step You Should Follow

It’s usually old roofers in Glasgow and Paisley and then after that, after you figure out your deck and your spacing if everything sounds good and looks good. You can walk on it now and it’s all solid now you’re ready to install your system the first accessories that you want to pay attention to it’s a drip edge it’s highly recommended to install drip edge on any roofing system doesn’t matter.

If it’s four twelve or like whatever piece of the roof it is you have to install drip edge what it does the water if any water ever gets towards the end and start dripping back towards the house it’s gonna kick out of your fascia and keep the water away from your the foundation from fascia from going to your siding and your soffits and we see a lot of damages.

When people don’t install drip edge what’s happening is water drips behind and starts making damage to the house to the foundation so drip edge is a must and then what you do is in a lot of especially up north you wanna install peel-and-stick or I some water barrier here in Minneapolis we usually, go with the two courses two three-foot sections on something like this but it’s not going by foot on the roof.


It has to clear the interior wall and the rule up north you have to have ice and water to feed behind interior walls so six feet what we have here in most applications more than enough so it’s going to do the trick sometimes you have to go three and sometimes you if it’s less than four 12th peach you have to do the entire house with the peel-and-stick also known as I called ice and water berry and why you need that is to prevent from any potential ice damming any uplifting wins when water will be dry going for any reasons up ice and water barrier will protect that as well so the next very important accessory in today’s asphalt roof installation is a synthetic foul paper back in the day was fifteen to thirty pound fell papers.

Now there are over a hundred brands on the market for synthetic fail paper doesn’t matter which one you use what’s important is to use the same brand with your manufacturer. This is own a scoring system so each manufacturer has its recommendations and each manufacturer these days wants you to use their accessories for the premium warranty. Warranty is the key for asphalt shingles because if you want to do it right you want to register with the manufacturer for those manufacturers pretty much on your roof in the future.

So if you’re a roofing company gonna go out of business your manufacturer will come back and say yes you use all our accessories you did everything right roof failed you have a leak we’re gonna take care of you. Now if you’re gonna go cheap and you’re gonna start substituting with the cheaper materials.

Just use a shingle from the brand and nothing else your warranty will be voided all most for any manufacturers out there so synthetic foul paper is very important it doesn’t matter which brand but for the warranty, you want to make sure you use the same brand.

We highly recommend the upgrade to synthetic fail paper I don’t see any reasons why not the synthetic fail paper is cheaper than fifteen or thirteen-pound old-school paper and the reason it’s cheaper because the coverage is so much more one roll of synthetic felt paper covers pretty much ten squares these days back in the day it would be like five rolls or five-six rolls of a regular 15-pound paper and you would have much more waste you would have much more cuts so next guys I want to talk about starter shingle back in the day.

I would say five-ten years ago was very very common when the roofers simply would take older shingles the one may be just coming off the roof or something they already have in a truck the previous job they would flip it around and they would put a shingle on top of it.

While it looked good and people think it will do the job the problem with that is the first nail of the roof actually would be about five inches from the end right in here. So the problem with that when you have a width from here hitting it hard you can damage your shingle very very easily because nothing here is actually attached and shingles this seal right.

Here supposed to be activating on the starter strip well the problem is when you flip other shingle this one here this strip will not be activated because you have granules here so when you use the starter strip for the starters how it’s attended by the manufacturer, you’re gone nail it in here which is much closer, and then this strip here will activate with the strip right here and you have a much stronger bond at the front.

So you’ll have nails much closer to the end and you will have nails still five inches here with a double seal pretty much one inch from the roof so it’s much better protection for the first course and that’s crucial because that’s where I wind will be will have the most power to trying to lift the shingles from your roof so definitely don’t go cheap.

I see a lot of roofers still cheating to this day because starter shingles do cost a little bit more but again it goes towards that warranty if you did not use your roofer doesn’t use starter strip shingle and use anything else it’s pretty much gone be affected your warranty right away and you will lose that warrants it.

So do not go cheap on starter shingles so OC has much better strips than most competitors that’s one of the features we like about OC roofing systems it’s really wide I believe it’s the widest starter strip on the market other brands have much smaller and it’s not as impressive but anyway follow manufacturer instructions when it comes to starter strips and the rest of the accessories so in the last piece of accessory guys.

It’s actually hip and reaches shingles so this one here is the pro edge pretty much every the manufacturer has specifically designed shingles just for the peaks and that’s also very important.

Because I see from back in the day a lot of roofers they’re being cloudy you know your three tap shingles and shingles just from regular roofs so back in the day roofers were using regular shingles just cutting them up and making them their hip and area shingles.

So now most manufacturers produce specialty shingles and I still see roofers do what they always been doing just because they know how again the problem is that warranty no matter what she do always follow the manufacturer’s instructions. If the manufacturer wants you to use their hip and ridge shingles and saying that that’s what you have to do for the warranty I get it a lot of guys I’m seen it many times you can go in and chop this shingle right now.

Make hip and very single out of that or some other three type shingles it’s doable it can be done it’s not right you want to do what manufacturers want you to do if manufacturers designed especially shingles which is hip and reach you want to install it.

I get us sometimes we have to fight insurance company. For example, don’t pay extra to install keeping every single hip and ridge shingles cost more you have thirty dollars for a regular bundle and you have forty dollars for hip and reach it’s more money but to do the job right you have to follow instructions insurance companies or whoever’s paying for the job have to pay extra for starters for hip and reaching goals.

Because it’s a lot of work it’s a lot of extra work but when you do it right you’re gonna have a premium system premium roofing system for you and warrant you. This is how you install shingles in 2018 a lot of things changed a lot of things are still the same. Hope it helps good luck out there and makes sure you’re safe to make sure when you get on the roofs you buckle up we’re here right.

Now we feel pretty safe it’s a 4-12 one level house but I highly recommend tie-down systems especially if you’re a homeowner and you’re not on the roofs on the everyday basis I highly recommend you think about safety first because doing all of this whether you’re doing a demo or you doing you know carry-outs and you know bringing all materials and tools to the job sites.

It can be dangerous you don’t want to hurt yourself if you consider professionals make sure you ask them during the interview during the estimate process what processes do they have as far as the quality control goes who does the job if they follow manufacturer instructions have their register warrant just because a lot of roofers their roofers they know how to install shingles but they don’t know how to follow manufacturer instructions when it comes to warranties and things like that so you want to make sure that your roofer has your best interest not only for this year but 10 to 15 years down. The road because your roof is not going to be there for three years.

It’s gonna be there for 30 years and you want to make sure it’s gonna last and if it fails somebody is gonna pay for it and hopefully, it’s not gonna be you thanks a lot for coming guys.
