Frequently Asked Questions Regarding Seamless Gutters | Glossary of Common Rain Gutter Terminology

Q. Why install gutters on my home?

A. Without gutters, rain that runs off of your roof will collect in places around your home, causing rot damage to exterior doors and windows, and other wood which can result in extensive damage and expensive repair work. This run-off water can also damage landscaping, erode your lawn, and will eventually compromise your foundation.

Q. What can water damage do to my home?

A. Moisture, in all its physical forms, is commonly regarded as the single greatest threat to the durability and long-term performance of residential homes. Over time, excessive exposure to moisture can cause significant damage to many types of building components and materials, namely corrosion, insect habitation and wood rot. By controlling exposure to moisture, many other durability problems such as mold and indoor air quality, which can lead to unhealthy indoor living environments, can also be solved. There is wide agreement that successful management of moisture in its various form is essential for houses to be safe, durable, and energy efficient. Foundation drainage is an important determinant of overall exposure to moisture. It is essential that rainwater and roof drainage be diverted away from the building perimeter to prevent leaks into basements or crawl spaces, or saturation of the ground around slab-on-grade construction.

Q. Why ACE Gutters?

A. The Designer Gutter is durable. We’ve seen how easily some gutters get damaged by ladders and that’s why our installers are the ones with “horns”.
The appearance of your home is important. We use "hidden gutter hangers" to fasten the gutter to your home. The hangers are "hidden" from view on the outside, giving your home the clean, SEAMLESS look. Plus, they’re stronger than the traditional "spike and ferrule method."
The installation magic continues when each section of seamless gutter is roll-formed to perfectly fit on your home. By using the same material found in seamless siding, each seamless gutter is installed in either a matching or complementing color.
