Common questions
What homeowners ask about re-roofing.
Can you install over my existing shingles?
In many cases yes. Depends on condition and local codes. Colum assesses this during your consultation.
Do you offer financing?
Yes. We offer financing options to make your forever roof affordable. Ask Colum for details.
Do you handle the tear-off of my old roof?
Yes. For full replacements, we handle complete tear-off, deck inspection, and disposal. We also do a magnetic nail sweep of your property afterward.
How long does a metal roof installation take?
A typical residential metal roof takes 2–4 days. Simple roofs may be completed in a single day, while larger or more complex projects (churches, steep pitches, multiple turrets) can take a week or longer. We'll give you a specific timeline during the quoting process.
What happens with cleanup after installation?
We want your property to look like we were never there. At the end of every job, crews use leaf blowers to clear debris from decks and walkways, run magnets around the entire property to catch any stray screws or metal pieces, and go through gardens and landscaping for any debris. The site is organized at the end of every day during the project, not just at completion.
