All FAQs
What is the recommended gauge for residential roof flashing?
The code minimum is .019 inches (trim coil), sufficient for most homes; 24 gauge is overkill and adds unnecessary cost.
What are alternative methods for flashing installation?
Hand-folding tabs is an alternative, offering a precise fit for complex areas, though it requires skill and tools.
How should damage to the brick caused during flashing installation be repaired?
A mason should fix brick damage, not just with caulk, by repointing or replacing bricks to ensure watertightness.
Why is it important to discuss flashing style before starting a roof job?
Discussing style avoids misunderstandings, ensuring the roof looks and works as expected, saving time and money.
What is the cost difference between standard flashing and step-down notched flashing?
Step-down notched flashing can cost around $3,000 more than standard, due to extra labor and materials for custom cuts.
Is it necessary to redo roof flashing if it looks bad but is functional?
While functionality is key, if flashing looks bad, it might indicate installation issues. It’s wise to have a pro check it to prevent future leaks, especially under harsh weather.
How much does roof replacement cost?
Replacement typically costs $5,727 to $12,418, depending on roof size, materials, and labor.
Does homeowners insurance cover roof replacement?
Many policies cover storm-related damage but not wear and tear. Check your policy or ask your insurer for details.
What’s the difference between reroofing and replacement?
Reroofing adds a new layer of shingles over the existing one, while replacement removes everything and starts fresh. Reroofing is cheaper but less thorough.
When should I consider reroofing instead of replacement?
Reroofing works if your roof has one layer of shingles and minor damage. It’s not an option for two-layer roofs or those needing structural fixes.
Can I repair my roof myself?
Yes, for small tasks like patching leaks or replacing shingles, if you’re safe and skilled. Larger repairs or replacements are best left to professionals.
What is the average lifespan of a roof?
Asphalt shingle roofs last 15-20 years, metal roofs 40-70 years, and tile or slate roofs can last over 100 years with proper care.
How do I know if my roof needs repair or replacement?
Minor issues like small leaks or a few missing shingles can often be repaired. Widespread damage, structural problems, or a roof over 15-20 years old usually requires replacement. A professional inspection gives the clearest answer.
Are smart sensors worth it?
