Brand new roof or re-roofing with molding problem ? | |
My house was built in 1986, about 3000 sqft, 2 story and colonial style.
I noticed some black stains on the roof and was told that it was molding. No leaks(maybe not yet ?) and no shades or tall trees around.
When I got roofers for an estimate, some said it's ok with re-roofing meaning putting new shingles over the exiting ones. Others said they need to take out the old and put down the new shingles.
Can I have your expert advice on this ? Thanks.
Answers:
1If you have the typical shingles, your roof is reaching the end of its life. (Many shingles from the 1980s had 20-year warranties, while others had 25- and 30-year warranties.) I would consider ripping off the roof and replacing it, as your chances of the current shingles failing in the next couple of years will increase. Put on a new roof and have peace of mind for the next 20-25 years.
