Roofing in Shawnee
Big trees, older roofs on the east side, and some of the worst valley-debris problems in the county.
Shawnee has the heaviest tree canopy of the towns we serve, and it changes the work. The mature oaks, sycamores and silver maples through the older east-side streets and around Shawnee Mission Park drop an enormous amount of material onto roofs — catkins in spring, seed balls and samaras through summer, then leaves. It collects in the valleys and behind chimneys, holds moisture against the shingle, and rots the decking underneath from the top down. We find more soft decking in Shawnee than anywhere else in Johnson County, and almost all of it is under a valley or behind a chimney where debris sat for years.
The same trees put limbs on roofs every windstorm. Straight-line outflow through the metro regularly runs 60 to 80 mph, and a limb strike punctures shingles and cracks decking in a way that is easy to miss from the ground once the branch has been dragged off.
The newer sections — Clear Creek, Bradshaw Farms and the builds west toward K-7 — have fewer trees and more roof: steep pitches, long runs and complicated intersections. And all of Shawnee sits under the same hail as the rest of the county.
Practical advice for Shawnee specifically: keep the valleys clear, get micro-mesh guards rather than foam or brush inserts, and have somebody look under the trees after a windstorm even when nothing appears to be missing.
Questions from Shawnee homeowners
Trees overhang my roof. Should I be worried?
Somewhat, and it is manageable. Overhanging limbs abrade shingles in the wind, drop debris into valleys, and give squirrels a route onto the roof. Trim back to roughly ten feet of clearance where you can. The bigger practical issue is the debris load: keep valleys and gutters clear, because the water they trap is what rots decking.
There is moss and dark streaking on my north slope.
The streaking is almost always Gloeocapsa magma, an algae - cosmetic, though it holds moisture and shortens shingle life a little. Actual moss is more serious: it lifts the shingle edges and holds water underneath. Both are treatable, and zinc or copper strips at the ridge prevent recurrence. What you should not do is pressure-wash a shingle roof, which strips the granules and destroys it.
