Hiring help to clean moss on Roof, Questions!
This is my first post to this forum, We have owned our 1993 built home for a few years now but have never had to hire anyone to do any maint. or repairs yet.
We have a fairly good amount of moss built up on the North side of our 2 story home and we don't feel at all comfortable attempting to get up there and do the cleaning job ourselves, and really wouldn't know what we were doing if we did. It's my understanding that basically they use a power washer to remove the moss and then treat with zinc to inhibit further growth.
We plan on getting several estimates but I would like to know what people have paid (or what people that do this type of work charge)...we have called one guy so far, he will do a drive-by and call us with an estimate but based on what we told him (2100 sq ft house, 2 story) that it will run us about 250.00. He was basing this on about 1000 sq ft (one side of the house) however when my hubby told me this I questioned the Sq footage as our house is 2 story so the roof is actually covering 1000 sq ft....and we only need the north side done, so I am thinking it's really only estimated at 500 sq feet??
Also, I saw some postings on Craigslist of others that do this type of work, if I inquiry about an estimate from here, what kinds of questions should I ask....for example, should I expect they be bonded, licenced, insured? I mean, if they aren't Am I liable if they fall off the roof?
I'm sorry if my questions sound so naive, like I said, I've never hired anyone to do anything in or at the house so I am not quite sure where to find people that do this type of work and what to expect. (We got this one guy's number off an flyer)
Any experiences or knowledge you can share would be appreciated!
