How to Replace Rusty Corrugated Roofing Lead Head Nails with Roofing Screws

[@jedfrank9597]

Great video. Thanks for taking the time to make it. It's exactly what I'm looking to do this summer and was looking for the best way to go about it. Cheers.

[@MannixGarage]

Kia ora, thanks for the comment appreciate that thank you. Yup all the bits I got from Trademe as I found it cheaper doing it that way 🙂👍

Hi Everyone, in this video you will learn how to replace rusty corrugated roofing lead head nails with roofing screws. Take care 🙂

[@A-Bridger]

Thanks for an extremely helpful video. I'll be tackling this same task soon on my own roof. One question however, what should be done to replace the nails holding the ridge cap and barge flashings?

[@MannixGarage]

Hey thanks for watching glad you found the video useful. With the flashings and ridge cap, yeah still replace those nails if you find you have surface rust around them and carry out the same process found in the video. However if you find that there are large holes around the nail hole as a result of corrosion and where the new roof screw wont create a seal, for me I just had a handful of those so I just made my own flat square washers out of old roofing material I had and sealed with silicon with the screw driven through the middle (did the job fine). But if you have quite a few like that, probably best not use my method but to buy aluminium backed epdm roof washers or the screw and washer combo. You can get different outside dia. (OD) sizes maybe just go for a OD size that is bigger or similar to the lead head nail OD to be safe. Hope that helps 🙂

Awesome video man really helpful. Do you have any tips on patching small spots of penetrating rust??

[@MannixGarage]

Hey there, good question. Sand any small spots of rust, use a rust treatment similar to what I used in the video (I find it works well), prime with a good metal primer or if you want to spend the money a zinc rich galvanized paint, then paint with roof paint.

[@crsoaringkiwi]

Great vid, brought the same materials and ready to go 😊. Did you use the same screw/washer combination for the flashing?

[@MannixGarage]

Hi there, good to hear you are ready to go, great job to get done when it starts to cool down end of summer 👍 for the flashing, no don't use profile washer. I had very few rust spots around old nails on the flashing, i actually made my own washers using an old piece of corrugated iron, made a small washer by cutting it maybe 1 inch square, bending flat, drill a hole in the middle and using the same principle as some of my profile washers I also applied some silicon sealant for extra sealing measures. Thanks for watching and all the best with your repair.

[@fredhayward1350]

Very helpful indeed thankyou. What sealer did you use? and does it matter? Went to the Hardware shop and by crikey there's heaps of sealants....lol.

[@MannixGarage]

Hi there thanks for watching and I am glad to hear the video was helpful. I would tend to look for a sealant which is marketed for roof and gutter use or a general all purpose house exterior sealant which has good uv\weather resistance, and for me it was important I wanted a paintable sealant as with some sealants paint will not stick too it at all (plus I painted the roof after the repair). It would be best to pop into the hardware store and have a look and ask them that you are just after as sealant for your roof, if you are painting the roof I would ask for a paintable sealant (normally the sealant cartridge's will state on the side if they are paintable or non paintable). Hope that helps all the best with your repair, take care 🙂

Cheers thanks heaps.@@MannixGarage

[@jimrogers3540]

Hi can I do this without the profile washer?

[@MannixGarage]

Hi there, yes, you can. When you remove the old roofing nail and if you haven’t widened\damaged the hole that the nail was removed from and ensuring that the new roofing screw washer still covers and provides a seal around the hole you will be fine. Perhaps have some profile washers on hand in case needed. Thanks for watching 👀 🙂

[@shonakennedy5240]

Hi did you use the cr profiles/washers on every hole? We need to re=screw our roof and were told to use these on the high wind zones. Can we get flat ones for the flashing on the ridge line?

[@MannixGarage]

Hi there, Yes I found I needed to use the profile washer and EPDM seal on every hole that I removed the lead head nail because the screw wouldn't seal the hole originally used by the nail or only just covered the hole, either the nail hole was widened when removing the nail or had rusted out wider. I didn't find any flat washers but my ridge line capping wasn't too bad and for the few nail holes that were bad I just made up square flat washers out of some old roof flashing I had laying around, pre drilled them and used roofing silicon between the washer and screwed down with roofing screw. I've done this in the past and with repairs in 2014 and they are still holding strong. (I do intend to do a reroof down the track, and this will hold up in the meantime). Hope all goes well with your project cheers 🙂

[@deborahcotter-smith4092]

Where do you buy, or brand / manufacturer of washers and profile washers. Assistance appreciated

[@MannixGarage]

Hi there, what country are you located? If in NZ I can tell you the supplier I purchased from.

[@deborahcotter-smith4092]

Thanks for the response. Yes, located in NZ

[@MannixGarage]

@@deborahcotter-smith4092 I was hoping you would say that, makes it nice and easy. Jump on Trademe look for seller ja_bolt and search there listings for these items which I used the in the video. -Universal Roofing Screw Metal & Timber 6.2 x 50mm -CR Profile + Sealing Washers The prices are pretty cheap too. My roof is holding up well, so happy with the product A++ 😄

[@peanutaxis]

Hi. What do you do if the old nail snaps and you just can't get it out?

[@MannixGarage]

Hi good question, if you have some wide cutting pliers you can use those with something to lever against in the troth of the corrugated iron (eg piece of timber or pipe like i used in the video) and try pull the nail out, if its unlikely you will get it out, just punch the nail down below the level of the corrugated iron and just run a roofing screw down beside it, the profile washer will compensate for the wider hole. Hope that helps thanks for watching 🙂

[@peanutaxis]

@@MannixGarageThanks heaps, that's extly what I did - punched it down. I'm surprised how well a screw went in even with the nail there. Sometimes at a weird angle but no probs at all really.

[@MannixGarage]

@@peanutaxis Good to hear you got it sorted.

[@scurnow875]

Are you using 12G or 14G Galv Tek screws with neo washer? Size is hard to see on the video.

[@MannixGarage]

Hi there good question, the screw size is metric 6.2mm thread diameter x 50mm length. Looking at a metric screw size to imperial gauge table I found different results between 12g and 14g? however I think its 12g screw size by the looks. 6.2mm = 0.244094 inch and 50mm = 1.9685 inch for metric to imperial measures hope that helps. Thanks for watching 🙂👍

[@hfb17]

Its 12 gauge. 14 gauge have a bigger hex head and require a 3/8th drive bit. You were using a 5/16th drive bit.

[@MrClimbingdave]

what pad u using on the grinder

[@MannixGarage]

Hi David. I am using a Josco strip it disc made of Silicon Carbide Impregnated Nylon . I see them referred to them as disc or pad but if you google what I'm using it will show similar product. If using a grinder with the strip it disc to remove rust be careful not to move onto the surrounding galvanizing as it will strip that away quicker than say if using sandpaper or wire brush. Cheers 🙂

[@MrClimbingdave]

Thank you this video is so helpful
