A number of gutters come in do-it-yourself kits so that homeowners can install their own gutter systems and eliminate the need for professional installation. Despite their lightweight, seamless aluminum gutters are difficult to install without a team of assistants.
Seamless gutters are not manufactured in convenient short sections that are easily maneuvered by one person. Instead, to create the seamless pieces, the sections are produced in single, long pieces that must be installed by multiple people.
Traditional aluminum gutters are cut to fit, so standard sizes are suitable for most homes. Seamless gutters are offered in a limited range of standard sizes, but to achieve the seamless design, longer pieces must be custom ordered to size to fit your home.
Seamless aluminum gutters are still a cost-effective option for gutters, but the added cost of custom sizing is a disadvantage for most homeowners.
Seamless gutters do not feature seams along the length of gutter across the front of the house, but the gutters are not truly seamless. The joints at the corners of the home, at the ends of the gutters and at the outlet tube all contain seams.
Any seam has the potential to develop a leak over time. Seamless gutters have fewer seams than traditional gutters, but they are not impervious to leaks.
Aluminum is largely considered one of the most cost-effective and durable options for gutters, but seamless aluminum gutters are not completely resistant to damage. Like all aluminum gutters, seamless gutters are vulnerable to dents or bends in the gutter due to debris.
Most dents won't impede the function of your gutters, but large dents that require repair present a problem for seamless gutters. If a section of your seamless gutter needs replacement, you'll either have to cut out and replace a portion of your gutter and create a seam, or replace the entire gutter.
