Commercial buildings in Van Nuys, CA face heavy seasonal rainfall during the winter months, making an effective drainage system essential. Without properly functioning gutters, rainwater can quickly create problems throughout the property. When gutters are absent, undersized, or improperly pitched, water overshoots the roof’s edge and creates problems that extend well beyond a minor inconvenience. Correct gutter installation directs water away from the building envelope and protects the investment in both the roof and the structure below it.

What Happens Without Proper Drainage
A building without functioning gutters relies entirely on the roof’s edge to shed water, which sends runoff directly down the facade and onto the ground below during heavy rain. That uncontrolled water flow saturates the soil immediately around the building, and over time, excessive moisture can contribute to settling, cracking, or water intrusion into lower-level spaces.
Water running down the face of a building also takes a visible toll. Staining, streaking, and gradual erosion of the facade material are common results of water repeatedly flowing over the same surfaces without a gutter system to redirect it. Entry points such as doorways and loading areas are especially vulnerable, since pooling water near these locations creates both a maintenance headache and a safety hazard for anyone entering or exiting the building.
Quality Gutter Installation Solves These Problems

A properly installed gutter system captures water at the roof’s edge and channels it through downspouts to a location where it can drain away from the building rather than pooling against it. By directing runoff away from the building, a properly installed gutter system helps prevent many of the problems associated with uncontrolled water.
Getting this right requires more than simply attaching a gutter to the roofline. The system must be sized for the roof’s square footage and the area’s expected rainfall intensity, pitched correctly so water flows toward the downspouts, and positioned so discharge occurs well away from the foundation. Each of these details affects how well the system performs during a storm.
Proper Sizing Prevents Overflow
Gutter sizing is based on the roof’s total square footage, its slope, and the rainfall intensity typical for the region, since a gutter that looks adequate on a smaller building may be seriously undersized for a larger commercial roof with a high volume of runoff. An undersized system overflows during heavy rain, which defeats the purpose of having gutters at all and can concentrate water in specific problem areas rather than distributing it safely.
Quality Gutter Installation Services
Gutter installation is often overlooked as a minor add-on to a roofing project, but the drainage system it provides plays a direct role in protecting a building’s foundation, facade, and overall structural health. A properly sized, correctly pitched gutter system pays for itself by preventing the kind of water damage that becomes expensive to repair once it takes hold.

FAQ
What size gutters does a commercial building typically need, and how is that determined?
Gutter size is determined by the roof’s total square footage, its slope, and the rainfall intensity common to the area, since these factors together determine how much water volume the system needs to handle during a heavy storm.
How does improper gutter pitch affect drainage performance, and what problems does it cause over time?
A gutter without the correct pitch allows water to sit in the channel instead of flowing toward the downspouts, which leads to standing water, debris buildup, and eventually corrosion or sagging in the gutter system.
Should commercial gutters be installed by a roofing contractor or a separate gutter specialist, and why does it matter?
A roofing contractor familiar with the specific roof system already understands how water moves off that roof and where drainage points need to be positioned, which allows for a gutter installation that works in coordination with the roof rather than as a separate afterthought.
