A house built in 2010 or later is usually facing its first reroof, most often after hail. These homes mix steep gables with low-slope porch roofs and standing seam accents, and their walls are often fiber cement or stucco. The checks that matter most are builder-installed details that may not match the manufacturer’s instructions (nail placement, ice barrier, starter, flashing), transitions between shingles and metal or low-slope sections, the attic ventilation design, and the warranty paperwork that will carry the new roof. This is general information, not an inspection of your home.

What newer homes usually have
- Mixed roofs: a steep main roof with lower porch, bay or entry roofs, some covered in standing seam metal.
- OSB deck panels and synthetic underlayment.
- Laminate shingles, sometimes impact-rated, often not.
- Walls of fiber cement, stucco or stone veneer, with several materials on one front.
- Rooftop equipment such as solar arrays and more roof penetrations for modern mechanical systems.
About a quarter of Denver County’s housing units and about a fifth of El Paso County’s were built in 2010 or later. In Douglas County, the median year built is 2004.
“Modern farmhouse” is a builder’s marketing label, not an architectural style with a set definition, so judge the roof by its shapes and materials rather than the name.
Known issues on newer homes
- Nails outside the nailing strip. Owens Corning’s nailing bulletin says nails belong within the nailing strip, toward its center or lower half, so they pass through both layers of a laminate shingle. A nail set too high can miss the lower layer and hold the shingle with less grip than intended.
- Shingle-to-metal and steep-to-flat transitions that rely on sealant.
- Low-slope sections below shingle minimums; see flat roof ponding.
- Missing kickouts where stucco or fiber cement walls meet a roof edge; see missing kickout flashing.
- Ventilation designs that changed from the original, such as spray foam added under the deck.
- Solar arrays that must come off and go back on during a reroof.
What you can check
- Find your paperwork: the builder’s warranty, any roof permit, and the shingle name if you have it.
- From the ground, look for lifted or missing shingles after wind, a sign the nailing or sealing may be off.
- Look at every transition where shingles meet metal or a flatter roof for caulk lines or stains below.
- In the attic, check whether the deck underside is bare wood (ventilated) or covered in foam (unvented).
The right scope and common shortcuts
| Right approach | Common shortcut |
|---|---|
| Nail every shingle in the manufacturer’s nailing strip | Fast nailing wherever the gun lands |
| Ice barrier at eaves and valleys as the instructions describe | Underlayment only at the eaves |
| Lapped metal flashing at shingle-to-metal transitions | Sealant at the joint |
| Keep low-slope sections on a low-slope system | Shingling a roof that is too flat |
| Register the manufacturer warranty and give you the paperwork | No registration, no record |
Code and manufacturer basis
The 2021 IRC as adopted in Colorado sets minimum slopes of 2:12 for asphalt shingles, with double underlayment up to 4:12 (R905.2.2), and 1/4:12 for standing seam metal panels (R905.10.2). Owens Corning’s laminate nailing bulletin sets where nails may go, and its wind bulletin says its shingles reach their ASTM wind classes with four nails, with six sometimes needed for enhanced warranties or local code. Its unvented deck bulletin excludes spray foam and unvented attics from extended warranties. Its Platinum Protection warranty must be registered by a Platinum Preferred contractor within 60 days and becomes void if a claim leads to the entire roof being replaced. Owens Corning also states that a class rating does not guarantee a shingle will survive hail, and its shingles are not warranted for hail damage.
When to call a roofer
Call after any hail or wind event, or if you see lifted shingles on a young roof. If hail brought you here, compare shingles with our IBHS impact ratings guide and see the Owens Corning installation requirements a proper install follows. Older houses are covered in the 1980s to 2000s guide and the home era overview.
