Common questions
How does roof sealant benefit my Washington D.C. home?
Roof sealant is applied to fill small cracks and seams on your existing roof, creating a watertight barrier. This application is beneficial in Washington D.C. to prevent small leaks caused by rain and humidity. Using sealant can be a cost-effective way to maintain your roof's integrity and extend its service life.
What are the steps for installing a new roof in Washington D.C.?
The installation process begins with the complete removal of your old roofing material down to the roof deck. We then inspect the deck for any damage and perform necessary repairs. A protective underlayment is installed, followed by the new roofing material. Flashing is meticulously placed around critical areas like chimneys and vents, and all edges and seams are properly sealed.
Does the 25% rule apply to roof repairs in Washington D.C.?
The '25% rule' often refers to local building code interpretations. If more than 25% of a roof's surface is damaged or needs repair, some jurisdictions may mandate a complete roof replacement. We assess the damage to your Washington D.C. home's roof to ensure compliance with these regulations.
