Common Questions

As a homeowner in Rancho Santa Margarita, my roof has ventilation issues and the underlayment seems worn. Can you help?

Absolutely. Poor ventilation and deteriorating underlayment are common local issues we address regularly. Our team starts with a thorough roof inspection to assess the specific condition. We then provide solutions that may include repairing or replacing the underlayment and improving attic ventilation systems. This targeted approach helps prevent heat and moisture buildup, which can extend the life of your roof and improve energy efficiency in your home.

Does Montross Companies handle both roofing and deck construction projects?

Yes, we are a full-service company licensed for both roofing (C-39) and related construction. We can manage building additions and deck construction projects, ensuring they are properly integrated with your home's existing structure and weatherproofing systems. This integrated approach is especially valuable for projects like covered patios or second-story decks that require coordination between roofing and framing expertise.

What does your preventative maintenance service for roofs typically include?

Our preventative maintenance program is designed to identify and address small issues before they become major problems. It includes a detailed roof inspection, gutter cleaning, checking for moisture control system integrity, and assessing flashings and seals. For commercial and multi-family properties, we develop customized maintenance schedules. This proactive service helps protect your investment and can often extend the time between major roof replacements.
