  • Do you use roofing subcontractors?
  • How long will the project take?
  • Do you have homeowner references?
  • Will you update me throughout the project?
  • How long should my new roof last?
  • Does your roofing work offer a warranty?

Is it ok to put a metal roof over shingles?
It is possible to install a metal roof over your shingles safely provided it is in line with the local building codes. Remember, laws may require full tear-off in case a new roof is to be installed.

What is the best time of year to replace a roof?
The best time to replace your roof is from late spring to early summer. During this time the rains have significantly subsided. Besides, the extreme humidity and heat of summer have not yet begun.

Do roof sealers work?
A good roof sealant should last up to 15 years. Most waterproofing roof coatings come with 10+ years warranty meaning it is as effective at least as the warranty. However, annual maintenance, as well as inspection, is necessary after the weather impacting event.

Can I pressure wash my roof?
A high-pressure wash on shingles can cause striping of granules. Therefore, it isn’t advisable to use a high-pressure washer on your asphalt shingles. Similarly, pressure washing tiles will erode the finishing making it need more cleanings.

On average cleaning, a roof should be done from after five years since installation, and you should use a soft wash system that uses low pressure. Low pressure doesn’t loosen or cause damage to the roof.

How do you estimate a roofing job?

Then get the size of the roof to determine the squares or shingles to install. Begin by measuring ground-level squares and roof pitch. With this information, you can determine the cost of material, labour cost and overhead cost. And when working with a contractor, they will add a profit margin on top to help run their business
