At times when three tab singles are flat enough,
installing a roof over the existing one is acceptable.
Nesting is allowed by manufactures in these cases. We
always install new flashing no mater what roof system you
choose. {Careful selection of products can let you re-roof
an existing architectural single in Owings Mills but due
to the uneven surface and sealing of the tabs this is a
summer time job.}
When should you replace your roof over repairs? A new roof
can cost $5,000 to $10,000 thousand dollars...
