Frequently Asked Questions

Below are common questions Sierrans Roofing Ltd. gets from customers.

When is it time to replace your roof?
Various damage that can compromise a roof system. It can be hard to know where to begin to look and, often homeowners aren’t really sure what they are looking for. That’s why it is a smart investment to hire a roofing professional to perform a roof inspection periodically (at least once a year).
My roof leaks. Do I need to replace it?
A leaking roof is a bad thing, however it doesn’t necessarily warrant a complete roof replacement. How much repair and work needs to be done on your roof depends on the level of damage caused by leaking. Talking to a Professional is the best way to know whether only minor OR a full roof replacement is necessary.

There are many problems that can lead to roof leaking, which is why it is important to inspect your roof periodically and check for common warning signs. You can perform this inspection yourself, but it is a good idea to hire a professional at least once a year to check for any serious roof problem.

How long will my roof last?
25 years is the life expectancy of the average roof system.

The life span of a roof system is determined by a number of factors, like: roof system design, building structure, material quality, material suitability, proper installation, periodic maintenance, local climate, and much more. Material quality is specially important because some roof system types such as clay tile, slate and (certain) metal can last longer.

When choosing the material for a new roof (or when hiring a professional) make sure to check the warranties of the materials. Most roofing manufacturers offer warranties on their products. You should be weary of any manufacturer that doesn’t.

I have moss on my roof. Can you remove it?
Sierrans does moss removal for existing roofs and can install chemical strips to prevent roof moss in the future. We also spray moss prevention in the attics of old houses.
Do you change rotten sheathing underneath the shingles?
Once the shingles are off, we evaluate any rot in the sheathing underneath and provide you with an estimate if this needs to be replaced. This is often difficult to estimate until the shingles are removed.
How many days will it take to replace my roof?
The standard sized roof would be done in two to three days. Our estimator will explain how long the project will take.
How do I verify a roofing company is a qualified roofer?

Ask to see the Roofer’s trade qualification Certificate, or interprovincial red seal Certificate. The number on these certificates can be checked with the Industry Training Authority (ITA)www.itabc.ca
