I'm a builder, I would do a full inspection of the loft first, the holes where not caused by you, it's just very old felt, on thing I would say, never spray up words towards the ridge tiles, always spray down towards the gutters, so angle your turbo thing in the direction of the gutters

I've just watched this closely and hears my 2 cents, first of all. With that many holes in the roof lining ill bet you didnt cause not one of them ! The tiles on the roof take most of the force from the turbo nozzle and what water gets behind it shouldnt put holes in it! That roofs been patched up allot so there was a problem there to start with. The lady mentioned that water got in through the boiler exhaust pipe, now that one could have been caused by rinsing down the roof and some water going down the pipe, you can actually see the dirty pipe in the vid. Think you did a great job there for your first one, next time take lots of pictures and inspect everything.

Ive blown tiles off a grade 1 listed building . Its always best to aim downwards . From the tip of the roof aiming down . Cat ladder is the safest method without braking further tiles in the job . Absolute perler mate 👌🏼

Only advice I will give you before you do any roof cleaning is go around the property take pictures of any broken tiles or damage already on the roof, go up into the loft before you start the job as well, and if you notice any damage or anything take photos before you start, if any customer complains u can prove the damage was already there before you started. Nice work on the roof clean👍 Hope you have plenty more in the future.

And make sure you have good third party liability insurance as well.

I’m a plumber ( often in roof spaces) and there’s plenty of lofts with random tear holes just like those in the older felt a long time before roof washing was a thing , it had a lifespan of 20-30 years but extreme conditions can cut that time dramatically

Hi mate, from what I see you did fine. I would be surprised if you caused the damage to the roof. I've cleaned a lot and not had that before. Potentially, when resting the turbo nozzle on the tiles before pulling the trigger, you get a build-up of compressed pressure, as you know. And there is the slightest possibility that is what may have caused the damage. I would expect to see broken tiles or clear signs of damage from the outside though if that was the case. Anyway... get shot of the bin lid thing you were using looked like cheap tat lol buy mosmatic they are worth it 👌

Thanks for sharing such an honest video of success and failure. IMO I can't see how you could have caused the visible damage inside the roof but fantastic job to remedy for the customer. Possible you caused some minor issues as you were learning but far more experience heads have commented on technique. All in that looked a very stressful experience, I feel your pain. (especially trying to handle +35ft of extended pole for any length of time)

It is really helpful for people to see things that go wrong, not just perfect things, so thanks for that. I use a pressure washer at home but have to be so careful (and don't use it on the roof which is even steeper and higher than the average 2 or 3 story house) and even on a bit of fence it has made a hole. It is just too powerful for some jobs I'm afraid. Also a lot of houses have loose tiles so I wouldn't feel safe using a powerful pressure hose

Love this video I've been doing this for 7 years I would like to give you advise use a ladder standoff and put it on the tile it give you stability stop your ladder wobbling and never put your ladder on the gutters you could pop a joint out of place but love the vid

Great job matey! That clearly wasn’t your fault at all. As you said in the video a scaffold every time will help. Don’t get to down with the armchair critics in the comments. These guys forget they started somewhere as well when cleaning roofs. Lovely job in the end mate and it’s a great service to offer to build the business. When I do roofs I pay my labourer more for that roof clean than I would on a general gutter or driveway day. Keep going mate 👍🏻🫡

Hi Jake, that damage was probably already there. Always a good idea to take a look round in the roof space before pressure wash. Lots of pros and cons to pressure washing roofs and water will always find a way to ruin your day lol. Keep up the great work 👍🏻

Nice job Jake, don't beat yourself up about the felt it was already knackered but defo look out for that next time. I clean a lot of roofs with skyscraper and biocide. I leave jet washing roofs to the guys who have the time to clear up the awful mess & don't mind risking their liability insurance.

Thanks for the video, my old roof felt perished and looked very similar. I doubt it was your doing but offering to have a look in the roof or asking the condition seems prudent, particularly if the property is 50’s - 80s and still on the original roof. I was up in the roof of a property the in-laws are buying and the felt membrane is also shot to shit. Great to see your patch work, it looks like a great temporary fix that I might need borrow and perform in due course!

You couldn’t have made them holes Jake you just blasted a tile surface. That old tar felt is very brittle but you couldn’t have done it. When roofers put battens on they can often rip the felt with their boots. Felt is just a back up not the waterproof surface. Like you said check the felt first take photos it will cover you.

It's strange that the "nice lady" didn't check the loft before you did the job. You have learned a valuable lesson, record evidence before it is needed. Job well done.

I would say those holes in the felt were pre existing as its old and will perish over time but because of the extreme pressure the water has penetrated through the tiles upwards and leaked straight into the loft through any holes in the felt This is why I don’t think it’s a good idea to clean a roof in this way , roof tiles like this aren’t meant to withstand pressures like this I’ll bet this happens all too often Nice to see you went back and addressed the issue 👍

Been in the business myself for 25 years, although in Belgium. That lining is detoriated from age. You simply cannot blast that with your nozzle, that is impossible. If it was, the the roof lining was already prone to outer damage because of gaps and broken tiles. Next time, do a pre-work inspection, also on the inside, to prevent things like this happening. And if something occurs, have it repaired by a roof-specialist, don't go DIYing with tape and plastic sheets....

morning.... as a fully quailed roofer of 35odd years I would say that non of the holes in the roof were caused by yourself. the undefelt is know as 1f a hessian and bitumen build up that is very very old and falls apart when people go into the loft and rub/nudge against it. modern day felt is like paper and heavily breathable to allow heat to dissipate correctly from the property. please forgive me for putting my 50ps with in...... but dont shoot water near any roof sill vents ,headworks,chimneys especially as they are all acting like a candles wick into the property and allowing the possibility of wart ingress.. keep on doing what ya doing as every day is a school day..... hope thus helps and remember....... be kind to yourself

Definitely needs re felting. You didn’t cause any of those holes. Unfortunately water probably did get up under the tiles and in through those holes, but you did a cracking job on the food for your first go! 👊🏼

How is that loft ventilated? That roofing felt looks like the non-permeable stuff that used to be used. At my place, it has lots of holes that I assume were punched by the roofers when the installed it, as ventilation. I saw some condensation on the material so I followed advice and cut a hand-size flap near the top for more ventilation.

All a learning curv mate! Would love to know what the issue may be. Fair play for recording it all some people would just blag everything was fine.

Bungalows suffer condensation and damp and sometimes people put holes in the felt for ventilation ….. I’ve seen it before

Nice job! I started in on driveways I have too much anxiety to do houses in case I have some disasters lol, maybe one day.

As people have mentioned do a pre-loft inspection with video and photo evidence of any current damage (actually show them this footage as they may be completely unaware) Also get them to sign something that says they’ve seen the pre inspection damage. (Maybe get a marker pen or Small piece of tape to mark the original damage spots so it can be much easier to determine after the work is complete if any damage that doesn’t have a mark on would’ve been caused by you)

Hi bud to stop the moss running to the drains disconnect a section of gutter at each side and set you're sheeting under that this also helps with the weight of the moss in the gutter, we never high pressure wash them always low pressure as low as our machine will go. People say it takes this and that of the roof if you are careful it will only lift the top layer of moss you will work out distance. It will take 50 60 years of a roof is the things I hear none of us will be here to see it and its rubbish if done properly

I feel if you were located at the peak of the roof and shooting the pressure water in a downward position. Which doesn't force water up under the shingle.

Jake don’t let it put you off done a good job there mate great video too! mistakes is how you learn. Doubtful you made them holes inspect next time 👌

Never had that happen, probably age of the roof. ( Did you lower the pressure on the p washer?) but most likely week or already failed liner. Maybe be worth inspecting the roof liner on qoute if possible could be a good idea. But I watch how you washed the roof and it seemed good, I use a twin turbo nozzle but also use a turbo devil disc cleaner which is awesome.

I well agree with @neverlandio: The holes are one thing and the infiltration is another one. To me Jake is not responsible for the holes (obviously) so he should not fix them, but he seems to be responsible as for the infiltration. So the question remains: Why some will use exactly the same equipment and seem to provoc no infiltration, when Jake apparently did ?.. The answer could be that the water did not get in through the tiles (otherwise there’d be water here and there in the Atic and espacially around the holes which does not seem to be the case), but somehow it did get through the boiler pipe (as neverlandio points it).

I think them holes were already there in the first place. Tape wise bitumen tape would stick better i think, its like glue the stickyness of it. You have done a good job on that roof 👍 i think if you take anymore roof jobs on def take a look inside the loft before and take photos and the show the owners.

Instead of using pressure why not use a 6% sh mix? Here in the us we use sh on tile roofs as well and if it has bad growth like your moss we broom it.

If you want a foot pedal I have left one on a job in Redditch I did before Christmas you can have it if it's still there customer said he put it to one side

soft wash is what needed to be done..never a good idea to apply pressure on a roof..nor on sidings of a property like vinyl or stucco..over all the roof looks great just gotta be careful with that pressure..wish you guys much success and keep rocking

Tip , get a couple of thick cleaning brushes from the shop and stick them in the gutters. Stops the need for you to clean the gutters out afterwards and keep it out the drain

100 bar maximum pressure, buy a decent turbo nozzle from ac pressure washers and don’t work up the roof that’s how the water can get in.

All I can add is that if you’re going to continue doing roofs, definitely inspect them from the loft. We’re in a 30’s semi and have no felt or membrane whatsoever. If we had it pressure washed it’d definitely leak.

It sounds backwards but I believe you're supposed to start at the bottom and work your way up, and then give it a rinse afterwards, otherwise you can end up with a huge pile of heavy wet moss as you get near the end that can cause damage, flooding or be harder to move. Just got further in the video and noticed that you are doing that later

3 ай бұрын

What you say is right but it's not the point here. Some are trying to know if the pressure equipment can cause infiltration through the tiles ... and if yes, could we avoid it (by directing the nozzle to better angle ..?.. or by using a lower pression..?).

The WetJet 14" Flat Surface Cleaner is also available on the lawn and power website. It is only rated up to 11 lpm. The nozzle orifices are probably too small for your machine. Luckily they are the standard 1/4” size so you could replace them to get the correct flow for your machine. I was actually looking at this FSC to pair with the lawn and power 3100 pressure washer which is 11pm.

And that's why you don't pressure wash a roof :(

Fit a pressure gauge and have the pressure around 90 bar to start with , that way you'll always be around the right pressure you'll need mate, also recommend and turbo devil so much easier

Boom! Just what i needed 😊

I'm inclined to say that at least some of those tears if not all of them were already there. As you said, it's already been repaired in places. That is very old roof felt. It degrades over time any way. Chin up mate, you did well.

Take photos of the roof when you price it and tell the customer you want a Quick Look in the loft if you see day light coming through

I think she took advantage of you to repair and patch those holes her roof was probably damaged before since you didn’t do a pre inspection

Good job, but invest in the moss matic and get ani vibration gloves 👍🏻

Use some CT1 on the patches

Nice clean work on the roof, just a shame it caused the felt issues. Me & my hubby live in one & ours was built in the 1970s identical roofing & he gets up with ladder's walks the roof to the top with the hose pipe & works from middle of roofing & just hoses it off & it still lightens the colour of tiles & other times before Moss builds up to quickly, he waits till the sun as burnt it dry & brushes it off in sections & lines the base of the property like you both did. Shame it went as it did as your both clean worker's & take everything around you into consideration, as there's some right cowboys out there who couldn't care less.

Maybe u shud get a cheap walk talkie system saves you shouting information u can just use your radio it might help especially when u want the pressure raised or lowered thought it might help good luck

Did you stop in one place to long?

roofer of 40 years......shouldnt use any presssure washers on roof....steam cleaning only........the pressure washers take the top layer of the roof tiles and cement off making everything pourous and also invalidate any roof warranty or manufacturer warranty on tiles which is normally 50 years......that said you look like competent and tidy workmen and your obviously not afraid to show the downsides as well which takes balls, if your mums boyfriend is a proper roofer surely he would advice you how bad for a roof this is.... The felt in that roof is 1F which is notriously rubbish after a time........ Tape is useless you need a bitumin adhesive... you also need to shape the felt slightly tapered when repairing so it is out at the top and goes in at the bottom so the water runs downb the felt.. I think you was just unlucky and got the nozzle at some funny angles... that felt hasnt been used for 20 years so that felt in that roof is 20 years plus who told you the felt is to stop wind??? if the roofs done right you shouldnt get any wind.

Can’t see that you would of caused that damage

I don’t think you were responsible with the holes in the felt I think they were already there no way could the turbo nozzle penetrate through the tiles, not less the interlock on the edge of the tile was already damaged in that case, it would not of been your faultyou need to inspect the attic space first, otherwise just going to cost you a lot of money in the future

You can’t be sure the turbo nozzle is what caused those holes… they could have been there before you started and the excess water gave them away… do an inspection with pictures and you shouldn’t have any issues.

Here's a thought...... Who the hell wants their roof cleaned??? Jeezuz, the worlds gone absolutely mad!!!! I've always been told that you leave that well alone.

Soft wash

You can fit scaffolding in a Sprinter van.

Nightmare, you go to do a job with all your best equipment and something goes wrong , I do think the age of the roof has to be taken into consideration before a clean is carried out as tiles can become weak and degraded over many years of been exposed to all sorts of weather eg hairline cracks , the question is how do you spot signs of damage on a roof covered in moss ?

Pop around ASAP and mop it up , that's all you can do mate

I would say the felt was already like that no way you could have done that as for the fsc I would think wrong jets and you may have to turn the pressure back up as you are running 2 nozzles rather than the 1

Work from top to bottom then when your arms are aching it’s getting closer to you so your not holding out as far

That tape a glue bodge wtf 😂

Them holes aren’t from your nor are they your fault they are from the roofers/chippys that done the extension! Coming from roofing you shouldn’t use pressure on roofs either

The clue is that there were previous repairs . I don’t see how your work could have caused the holes. The water in the airing cupboard could have been you being careless rinsing down and getting water into the flue.

mosmatic is the only thing for the job

Honestly I can't see its being your fault, if the tile has no hole there is no way you can damage the felt under the tile.I have washed exact same tile roofs for 3 years now and never had any issues, and yes tiles should protect the roof from water not the underlay.Only thing is that I use hot water and twin turbo nozzle, that way you work with lot less pressure and get same results.Heads up,you just got really unlucky that's all, always before you start cleaning roofs go around and make multiple pictures of the cracked tiles, damaged concrete etc, so customer wouldn't blame you.

You’ve done nothing wrong mate , the roofers have caused the holes and just put the tile over it . Your water wouldn’t penetrate the tile or you would see it as you were cleaning the tiles .

Soft wash it and them let the rain wash it off
