I need a professional to help with roofing in Cranbrook. Why should I call Ostash Exterior Building Products?

If you need a new roof installed or a repair on your existing roof, trust us to make the process easy and affordable. We are trained to install and repair all different types of roofing to keep your home secure, aesthetically pleasing and protected. We offer several styles of metal roofing and asphalt shingles.

What is the difference between metal roofing and asphalt shingles?

Asphalt shingles are more affordable upfront than metal roofing, making them popular among homeowners on a tight budget. These shingles are easily maintained and come in all different colours and styles.

Metal roofing is more durable than asphalt, so it can be economical in the long run (although the initial cost of installation might be higher). Metal roofing is also energy efficient, saving you money on heating and cooling bills.


I heard Ostash is the place to go for siding in Cranbrook. What types do you carry?

At Ostash Exterior Building Products, we carry all types of siding including vinyl, James Hardie, Can-Exel, Smart side and faux rock. Quality siding can give your building a fresh, newly renovated look all on its own—and it will protect your investment.

Why is it important to maintain the siding on my house?

Keeping your siding in tip-top shape is critical not only for aesthetics but for damage prevention. Siding helps maintain the structural integrity of a building and protects it from the elements. It can also boost resale value and lower energy costs if installed by a skilled professional. Give us a call and we can come to do a free on-site estimate to see if you need siding maintenance or replacement.


Are seamless eavestroughs and gutter guard products worth it?

Is gutter cleaning a frequent hassle? We can reduce the need for constant cleaning with our gutter guard products, which stop debris from collecting and clogging up your gutters. Protect your investment and eliminate the need for expensive repairs down the road. When you look at the bigger picture, it’s well worth the initial cost of gutter guard products.

What types of seamless eavestroughs do you offer at Ostash?

We offer seamless eavestroughs in 23 different colours, so you can find the right match to any style of home. Seamless gutters and eavestroughs are wonderful because they look great, don’t leak and require less maintenance due to them being continuous and seamless.
