If the outside of your house is starting to look worn, dull, or cracked, you’re not just dealing with an eyesore; you’re facing a bigger issue. Neglecting exterior paint isn’t just a cosmetic problem; it exposes your home to the elements, accelerates damage, and can rack up costly repairs down the line.
After more than 25 years of painting, our Roe Painting team has helped thousands of homeowners understand how timing, material, and climate affect how often you need to repaint. We’ve seen firsthand what happens when exterior maintenance is delayed, and how much time and money a proactive paint schedule can save.
In this article, you’ll learn exactly how often to repaint your home’s exterior based on the surface material, the signs to look for before paint fails, and how factors like weather and location impact longevity. By the end, you’ll know when and how to repaint, so your home stays protected, beautiful, and valuable.
We'll cover:
Painting your home’s exterior isn’t just about looks; it’s a protective measure. Over time, your siding faces a relentless mix of sun, rain, wind, and temperature swings. Without a strong, intact paint layer, moisture seeps in, UV rays break down materials, and pests can find easy entry points.
What’s at stake?
Neglecting this layer of protection can lead to cracked siding, wood rot, mold growth, or even structural damage—issues far more expensive than a routine paint job. Even if your siding is newer, failing paint can still reduce your home’s market value and curb appeal.
A fresh coat of paint is your home’s first line of defense.
When applied at the right time and under the right conditions, exterior paint seals surfaces, blocks moisture, and protects against sun damage, thereby extending the life of your exterior surfaces while making your home look refreshed and well-maintained.
Real wood siding is beautiful, but high maintenance. It’s vulnerable to moisture, rot, and insect damage, which is why it needs repainting more frequently than other materials. Engineered wood siding, which is what most homeowners have on their homes, will last longer and can go 7 to 10 years between paint jobs.
Quick Tip: If your wood siding is stained rather than painted, expect to reapply the stain about every 3 years to maintain protection and color.

Maintenance Tips:
Stucco offers great texture and insulation, but hairline cracks are common. If left untreated, they allow moisture in, compromising the paint and the wall behind it.
Maintenance Tips:
Painted brick has excellent longevity, though it requires very thorough prep and moisture control. Unpainted brick usually only needs cleaning, not repainting.
Maintenance Tips:
This low-maintenance material, also called engineered siding, holds paint extremely well due to its weather resistance and stability.
Maintenance Tips:
Even if you don’t know the exact age of your last paint job, your home will give you clues when it’s time for a new coat of paint. Ignoring these signs can lead to deeper damage and more expensive repairs down the road.
If your paint is curling, lifting, or flaking off, your exterior surfaces are no longer protected. Moisture and UV rays are getting in, and the damage will only get worse.
Look for:
Sun exposure gradually breaks down paint pigments, especially on dark colors. If your paint looks washed out or uneven, it’s losing its protective power.
Pro Tip: Switching to lighter colors can reduce fading in high-sun areas.
Caulking seals joints around windows, doors, and siding seams. Over time, it hardens and breaks, letting water sneak in.
Look for:
Wood siding can shrink or pull away as moisture gets in. If you spot new gaps between boards or shifting trim, it’s a clear red flag.
Pro Tip: Don’t paint over damaged boards. Have them inspected and repaired first, then repaint to seal the surface properly.
Even with the right materials and timing, not all paint jobs are created equal. The lifespan of your exterior paint depends on more than just what it’s applied to—it’s influenced by your environment, your prep, and the products you choose.
1. Paint Quality
Higher-end paints contain more pigments and durable binders, helping them cling better, resist fading, and weatherproof your siding. Cheaper paints may look good at first, but they often break down faster, requiring more frequent touch-ups or total repaints.
2. Location
Where your home is physically located plays a big role. Idaho and Nevada homes near lakes, open plains, or at a high elevation get hammered with UV rays and wind. Urban homes in Boise might face more grime, and shaded lots are magnets for mold and mildew. Your geographic location affects how long paint holds up and what kind of maintenance it demands.
3. Climate Patterns
Think about what your home goes through each season. Rainy seasons? Freezing winters? Scorching summers? In Idaho and Nevada, we can see a little bit of everything (sometimes in the same day). Paint expands and contracts with temperature shifts, and moisture can sneak into tiny cracks, undermining the finish from the inside out.
4. Weather on Paint
Even the best paint can fail if it’s applied on the wrong day. Too hot and it dries too fast, which will lead to cracking. Too cold or humid, and it may not cure properly. Timing your project to the right time of year or even just the right time of day is one of the easiest ways to make sure you have a successful, lasting application.
5. Surface Preparation
Prep is everything. Skipping steps like pressure washing, scraping loose paint, sanding rough spots, or applying primer will shorten the lifespan of any paint job. Clean, dry, and properly primed surfaces are the foundations for paint that lasts.
The best time to paint the exterior of your house is during late spring, early summer, or early fall, when temperatures range between 50°F and 85°F and humidity is low. These conditions help paint adhere properly, cure evenly, and last longer without blistering or peeling.
Now you know how often to paint your home’s exterior based on material, climate, and warning signs. Staying on top of repainting protects your siding, boosts curb appeal, and prevents costly long-term damage.
