Roofing for lake living.
Open water means wind and hail hit lake homes hard, and a second home can leak for weeks before anyone notices. Standing seam metal is a favorite here: it stands up to sun and wind for decades with very little upkeep.
You don't need to be there. We inspect, send you photos of what we find, quote it in writing, and document the work as it happens. Lake-country trees fill gutters fast, so Leaf Terminator guards are worth a look on a house you don't visit every week.

Grand Lake roofs, by the numbers.
- 31% of homes were built before 1980, and 34% in 2000 or later.
- Homes from the 1980s and 1990s are often on their second roof, and any original roofs left from that era are past their service life.
Re-roof permit rules differ from city to city across the Tulsa metro. Before you sign, ask your roofer whether Grand Lake requires a permit for your job, who pulls it, and whether the work gets an inspection.
Any roofer working in Oklahoma has to be registered with the Construction Industries Board. Ours is License No. 80001347; you can look up any contractor on the CIB website.

Nearby areas.
Can you handle my roof if I'm not there?
Yes. We inspect, send photos and a written quote, and document the work as it happens, so you can manage the whole project from home.
Is metal roofing a good choice for a lake home?
Usually, yes. Standing seam metal lasts 50 to 70 years, sheds wind and weather, and needs very little maintenance on a house you don't visit every week.
Does RainTech serve the whole Grand Lake area?
Yes: Grove, Monkey Island, Langley, Disney, Ketchum, Afton, Bernice, Cleora and the lake communities around Grand Lake O' the Cherokees.
How often does Grand Lake get hail?
Since 2016, NOAA's Storm Events Database lists 12 reports of hail 1 inch or larger within 5 miles of Grand Lake, on 11 different days. Largest: 2.5-inch (tennis ball-size) hail near Grove, March 9, 2017. Most recent: 1-inch (quarter-size) hail, April 25, 2026. Hail that size can bruise shingles without leaving damage you can see from the ground, so get the roof inspected after a big storm.
Is the roof inspection in Grand Lake really free?
Yes. A hands-on inspection, photos of what we find, and a straight recommendation, with no obligation.
Does RainTech work with my insurance company?
Yes. We document storm damage, meet your adjuster on the roof, and review the scope line by line. Oklahoma law prohibits any contractor from waiving or paying your deductible.
