Question about potential mold in attic

[Fred Lutes]

Thanks so much for your great advice in the past. I have a quick question concerning potential mold: I am renting a 2004 built, 3 bedroom, 2 bath home in a fairly dry climate. My tenants informed me on Wednesday, (2 days ago) by text that they think there is a leak in the roof above the master bathroom and sent a picture of what looks like a slight bubble in the sheetrock paint about 2.5 inches in diameter. It was raining on Wednesday, so I told them that I wanted to wait until the roof was dryed out somewhat to get on the roof. I told them possibly Friday. It was still damp today, (Friday), so I told them I would be over Sunday or Monday. (I had mentioned to them that it was likely a worn out rubber boot on the plumbing vent or the vent for the bathroom exhaust fan because these were the only penetrations on the roof.) I also have a glass guy coming on Monday to adjust the patio slider because they had complained that the door was becoming difficult to open. I texted to them that the glass guy was coming at 11am on Monday, (I intend to meet him there).

After my text this morning, My tenant texted back: 'I am very sensitive to molds and have not been feeling well the last couple of days so please do  as I am sure you would ensure inspection is thorough for that and the bedroom smelled very musty when I got home from work last night'.

I texted back that the roof should be safe to walk on by Sunday and that I have a roofer coming over on Monday. (3 days from today.)

They texted back that 'You want to look at it from the attic asap before it dries out and would be most concerned about mold. I had to tear out a ceiling about 4 years ago for same reason.'

After this text, I decided to contact a local restoration company to test for mold and give me a report. The representative said that he could make it over this Monday, so I am scheduling him at the same time as the roofer.

My tenants of 1 3/4 years are nice people but demanding and recently used the veiled threat of a teenage son with emotional issues needing a service animal to 'persuade' us to allow a dog. (Another story which I resolved thanks to some excellent advice received here.)

Sorry for the long story but wanted to give some background for a better picture and am hoping to get advice. My opinion is that there is no mold and in our fairly dry climate, mold is very uncommon but not unheard of.

After arranging for the roof repair and inspection 3 days from now, is there anything else that I should do that would be prudent and practical.

Thanks in advance for your advice!
