Water Behind Aluminum Siding

Water damage is risky business.

Water behind aluminum siding. During a very heavy 2 days of rain water began running from between pieces of siding. When siding is put back behind the gutter the lowest piece of flashing running down the pitch of the roof above must be fashioned to divert water into the gutter not behind the siding. Some areas were extremely heavy while others were just a single streak. This can also cause your siding to rust.

At yanish we find water damage behind the siding of roughly 1 in 6 homes. If you do choose to have aluminum siding be sure that there s water resistant stripping underneath the panels. The damage can compromise a building s structural integrity. Not all have wood rot but the damage would progress to rot in time.

The presence of a housewrap on modern buildings or felt on older buildings combined with proper flashing at windows doors and other openings are relied upon to keep water from entering the structure itself. Walls longer than 16 feet. In a rainstorm water flows down one panel and onto the next so a strong wind can easily blow the water up under the panel where the wall is unprotected. Vinyl siding comes in 16 foot strips.
