ur sister company, Weather Out Flashing was founded in 2004 by Ross Allen Custom Builders.  After years of working in the custom home building industry, President and Owner, Ross Allen noticed an ever growing need for a better way to weatherize the installation of windows and doors.  After years of research, Ross Allen designed, tested and perfected multiple styles of head and sill window and door flashing products resulting in 6 patents. All our state of the art window and door flashing products provide a patented sloped pan design which channels water away from your home and prevents the occurrence of window and door water leaks in your home.

Our window and door flashing products are used in all our custom home designs and renovations. In addition, our window and door flashing products are being sold to builders and developers across the country.

  • Our family first met Ross Allen in February of 2015 when we inquired about a parcel of property he had listed for sale.   Following our initial meeting, we decided without reservation that Ross Allen Custom Builders would build our next home.  Ross as totally transparent with his intentions and willingness to adapt to our plans.  From the initial budget to the final cost, Ross kept us updated on schedules, allowed modifications in the process and has followed up on a timely basis with the few problems that have occurred.
    Based on our experience and recommendation, Ross will be building a new home for our best friends based later this year.  Had our experience been anything less than exceptional, we would not be in position to make such recommendation.
