Call for roof repair when you see missing or damaged shingles, gaps at flashing, leaks or stains, ice dams, granules in the gutters or signs of poor attic ventilation. Small problems fixed early rarely turn into a new roof.
- Failing gutters and ice dams damage the roof edge
- Gaps, missing shingles and loose flashing let water in
- Poor attic ventilation rots decking from the inside
- Storm damage should be inspected before it leaks
Keeping an eye on your roof can be the difference between a few hundred dollars of repair and a full replacement. These are the problems we see most often around Des Moines.
Gutters past their prime
Gutters are supposed to carry water off the roof edge. When they're clogged with debris, water backs up under the first row of shingles. In winter, ice dams add weight that pulls gutters loose and forces water under the shingles. Clean gutters, guards and good attic ventilation prevent most of it. See ice dams in Central Iowa.
Gaps, holes and missing shingles
Water is a roof's main enemy. Missing shingles, lifted tabs, gaps at flashing and cracked pipe boots all give it a way in, and once it reaches the decking and attic, mold and rot follow. These are usually straightforward repairs if they're caught early.
Poor attic ventilation
Your attic needs intake vents at the soffits and exhaust vents near the ridge. Without both, it becomes a sauna in summer and traps moisture in winter. Over time that warps decking, rusts nails and cooks shingles from below. Signs include frost on the underside of the roof in winter, a musty smell or curling shingles on an otherwise young roof.
Leaks and ceiling stains
Any water stain on a ceiling deserves a look, even if it dried up. See the most common reasons roofs leak.
Storm damage
Hail and wind damage doesn't always leak right away. Bruised shingles lose granules and crack over a few freeze-thaw cycles. After any big storm, check from the ground and get an inspection. Our hail damage guide shows what to look for.
When repair isn't enough
If a roof is near the end of its life, has widespread hail damage or keeps leaking in new places, replacement is often the better value. We'll tell you honestly which one you need. See repair or replace?
Quick answers
How much does a roof repair cost in Des Moines?
It depends on the problem. Our roof repair page lists common repairs and what they typically involve.
Can I wait to fix a small roof problem?
It's risky. Small leaks soak decking and insulation long before you see a stain, and Iowa freeze-thaw makes damage worse each winter.
