Gutters come up late in most roofing conversations, usually as an afterthought once the shingle decision is made. That is backwards. The gutter and the roof edge are one system, they have to be installed in a particular relationship to each other, and the cheapest moment to sort that out is while the crew is already on the eave.
The Edge Is a System, Not Two Products
Water leaving a roof does not simply fall into a gutter. Surface tension makes it curl back under the shingle edge and run toward the fascia, which is why edge metal exists: a formed strip that breaks that tension and throws water clear. The gutter then has to sit in the right position relative to that metal to catch it.
Get the relationship wrong and water runs behind the gutter and down the fascia board. That is the origin of most peeling paint under an eave, most soft fascia, and a surprising number of the wet basement complaints that get blamed on grading.
Why Gutters Often Have to Come Off Anyway
Installing new edge metal correctly generally means the gutters have to come off or at least be loosened, because the metal belongs under the underlayment at the eave and over the fascia face. A crew that leaves the gutters bolted tight and slides metal in behind them has produced something that looks finished and is not fastened the way it should be.
Once gutters are coming off, the arithmetic changes. Old aluminum that has been up for twenty years is brittle, and taking it down and rehanging it without damage is not always possible. That is the point at which reuse versus replacement stops being a preference and becomes a practical question.
When to Replace Rather Than Reuse
- Hail damage. Gutters and downspouts are soft metal, they dent visibly, and they are among the first things an adjuster reads after a storm. If they are damaged, they belong in the claim.
- Age and brittleness. Old aluminum cracks at the hangers when it is moved. If it will not survive removal, reusing it is theoretical.
- Sagging and pitch problems. Standing water in a gutter means the pitch is wrong or the hangers have pulled. Rehanging solves it; reusing does not.
- Undersized for the roof. A large or steep roof section dumping into a small gutter overflows in a Front Range cloudburst regardless of how clean it is.
- Fascia repairs underneath. If the fascia has to be repaired, the gutter is coming off for that anyway.
Doing It in the Wrong Order Costs Twice
Every year homeowners have new gutters installed and then replace the roof six months later, or paint the fascia the week before tear off. Both cost twice: once to install, once to remove and reinstall or to repair the damage.
The order that works is roof first, then gutters, then any fascia and elevation work. On an insurance job that sequencing matters even more, because the roof, the gutters and the elevation damage are usually all in the same claim against the same deductible. Our guide to reading your declarations page covers how that deductible is set.
Drip Edge, Gutter Apron and Which You Need
Two related pieces of metal do slightly different jobs. Standard drip edge breaks surface tension and protects the deck edge. Gutter apron has a longer angled leg designed to carry water over the back edge of the gutter, and it is the better answer on homes where water has been getting behind the gutter and staining the fascia.
If you have dark streaks on the fascia under the roof edge, or paint that peels only there and nowhere else on the house, that is the symptom this addresses. Mention it during the estimate, because it is a small upgrade during a replacement and a carpentry project afterward.
Guards, Screens and Centennial Trees
The older neighborhoods here carry mature canopy, and shaded slopes with cottonwoods and maples overhead load gutters continuously rather than seasonally. Guards can genuinely reduce the maintenance on those properties, with two caveats worth stating.
Guards reduce cleaning; they do not eliminate it, and fine debris still accumulates. And guards installed under the first shingle course can interfere with the roof edge if done carelessly, which is another reason to have the same conversation with the same contractor while the roof is open rather than hiring two trades six months apart.
Gutter Questions Centennial Homeowners Ask
- Do gutters have to come off to replace a roof? Usually they come off or are loosened, because new edge metal is installed at the eave in a specific relationship to the underlayment and the fascia. A crew that works around bolted gutters is likely cutting that detail short.
- Should I replace gutters at the same time as the roof? If they are hail damaged, brittle with age, sagging, or undersized for the roof, yes. If they are sound and can be removed and rehung without damage, reuse is reasonable. Decide it during the estimate rather than on the second morning.
- Why does water run behind my gutter? Usually a missing or undersized edge metal detail, or a gutter positioned wrong relative to the roof edge. Gutter apron with a longer angled leg is the common fix, and it is inexpensive during a replacement.
- Are gutter guards worth it in Centennial? On a property with mature trees overhead they reduce maintenance meaningfully, though they do not eliminate cleaning. Have them installed by whoever is handling the roof edge so the two details do not conflict.
