Hey everyone. I live in a small apartment building where the LL recently had our (white) rooftop repainted. Our LL rarely uses licensed professionals, and most plumbing, painting, etc. jobs are either done by him, one of his friends, or some random person that he found...god only knows where. As a result, jobs often are not done properly, and need to be redone, often then resulting in the original problem actually becoming worse, not better. (Sigh....)

Anyway, I'm just curious...what y'all think could explain the following...

The LL had the rooftop repainted, maybe a month ago, and the person apparently used a product called Gaco Roof 100% Silicone Roof Coating. (Whether the person used another product, in addition to the aforementioned one, I don't know...only that I saw a large barrel of the Gaco product, by the rooftop stairwell, after they'd redone the roof....)

Not long after, I started to notice that any time it rained out - and some water remained, pooled, on the rooftop - that the standing water created a reddish-purple area on the rooftop. (This never happened, prior to the rooftop being painted with the Gaco Silicone product. Anytime it rained, any standing water up on the rooftop had a 'normal' appearance and color.)

It also just so happens that...a new, more recent leak from the rooftop into my ceiling directly below has created a similarly dark, purplish-tinged stain, complete with a dark ring that almost looks 'acidic'... While I've had periodic leaks from the rooftop into my ceiling, in the past, they always looked like typical 'leaks', with a light water stain and perhaps a small 'bubble'. But this is the first time I've gotten a dark colored leak/stain in my ceiling.

I can't help but wonder if all of this is somehow related to the new silicone roof coating. But if so, how would that cause standing rainwater to turn reddish purple? Or maybe it's all pure coincidence, timing-wise, and something in the chemical makeup of our actual rainwater has suddenly changed, causing the reddish hue? BTW, this is in NYC....

Thanks!

I am planning to sand and refinish this front door of my house. I will need to sand it extensively, but am wondering if there is a sanding tool to make the sanding more effective.

They look like some kind of drainage pipe, do I need to keep these clear or should they have some kind of cap? Is the broken one a major concern?

Hi all, my husband and I just bought our new house and have settled in about 3 weeks ago, two days ago we noticed that on a doorway there was what looked like water droplets, we kept and eye on it and yesterday felt that one side above the doorway was humid/ warm and the other side was not upon further inspection we saw that the humidity was extending to the left side but wasn’t going all the way down the wall if anything it seems to stop randomly. We’re at a stump and don’t really know who to call any advice?

Some background: this is a modular home that was completely renovated from the inside upon asking neighbors the roof isn’t anymore than 3 years old

i’ve been living here for four months now, and this is the second time that water has seeped underneath my window seal under the wall, and I can see the water dripping down behind the wall. I feel hot air coming through the little crack as well. They’ve come in before and apparently checked for mold as well as resealed this, but the resealing has opened what could this issue be and is this common? Has this happen to anyone else? Also the first time this happened mold came on to the wall.

My basement was like this when I bought it. It has evidence of mold/mildew/efflorescence from water damage from the failed sump pump and the water collection under my stairs that lead to the outside. My brother is going to fix the sump pump and the door so it stops leaking when it rains how do I treat the damage and make the space livable

Hello all. The home we're living in is having an issue with our flooring buckling and coming loose. At first, I thought maybe the previous people installed it wrong, until I noticed the subfloor was getting weak. I crawled under the house and found the ground to be damp and wet, which, I'm sure you guessed, is creating moisture on the subfloor thus rotting it out.

The land is sloped starting from the front yard and grades down towards the back yard. Is this my issue? Excess rain water running under the house creating my moisture issue? Or is it a humidity issue?

The home has no vapor barrier, and I dont think I can afford to hire someone, or do it myself. Theres also no crawlspace ventilation on the siding either. Also, the full length of the porch, there exists no siding. Its completely open.

Thanks inadvance for any inputs. This issue is out of my wheelhouse and I like to fix it before I start my repairs on the subfloor.

Tl;dr: crawlspace is creating excess moisture that's causing the subfloor to rot. Too much rain? Humidity issue? Ventilation issue?

I did all the waterproofing but the damp isn't going away! How do I hide it?

Hello all,

I accidentally left one of those wall plug in air fresheners on my counter and it leaked everywhere. After cleaning up the mess, I tried to paint the counter white and now it’s like peeling and gooey still. What is the best way to clean the area and then paint it and ensure it’s not gooey after. Thank you! Please see picture for reference of how it looks.

Anyone know the correct way to fill these gaps? Some kind of exterior caulking? or only with mortar repair?

I’ve been gone from home due to school and work, so I haven’t been around much. My Mom sent me this photo of our garage ceiling. I’m not sure what the cause is. I was wondering if someone can find what the issue is? I was thinking a leaking pipe, but I’m not too sure…

Edit: Thank you all for the guidance, I’m having someone come out to check it out and see what the damage is to my wallet.

apologies for this being irrelevant here but i couldn’t find any other groups that allowed pictures.

I was stuck in my living room (the door handle is broken) and had to climb out the window and causes this damage. will this be expensive?

I live with my mother and her bf so I’m worried they’ll get angry when they see it.
