Composite Deck Surface Mount Post Bracket

They make a metal brack to span the old 2X4 and you most likely can get it to work for the new roof. If not I can most likely get some made at work. You do have some good bracing and support on the one footing you have pictured here and if the other one is the same way it would be just as strong.

I would just pull out the old footings and replace them with the new style footing and be done with it.

Reasons: 1) you would always have questions as to how strong the modified brackets (ie the roof/posts are) and 2) By replaceing the old footing /posts you now have done the job and will pass and inspector.

I have cleaned pine sap off deck chairs, deck table and cedar decking by first scraping with a plastic scraper. Then I wet a paper towel in turpentine and wipe off the remainder. Sometimes it is necessary to saturate the area to soften the sap so it can be removed by further scraping and wiping with the turpentine.

The deck chairs I cleaned this way had plastic fabric seat material and were not noticeably affected by the turpentine. Of course after using the turpentine I followed up with a wash using warm soapy water to remove any of the chemical residue.

I have every reason to believe that this cleaning technique would with the composite type deck materials. Since there are variations in material compositions it would be wise to check in a small inconspicuous area before committing the whole cleaning procedure.
