We have not used this product but are familiar with it. It is NOT a screen type. It's actually similar to Leaf Relief, which is a good product. A number of roofing contractors in our area (MD) use it and have had good sucess.

There isn't any perfect product out there. Thay all have there pros & cons. Do research based on your paticular area, type of weather and trees around house.

I am unfamiliar with this product but from your picture it looks similar to many of the screen-type products that are available on the market. As a roofing contractor who has been installing "gutter protection" for over 30 years, we tend to not encourage 'screen-type' products as the maintenance is difficult and frequent. We have been installing GutterTopper for over 20 years in Wisconsin and our customers are very satisfied with it's performance. All products require maintenance, but GutterTopper's is the quickest and SAFEST by far.

I believe a dealer in your area is Marshall Roofing.

I hope this helps. The screen you are considering is much like ones we often remove because of customer dissatisfaction. 

Can't say I've ever heard them doing it when they cool down, but when the sun hits them in the morning, it can happen. If they're mounted to an aluminum facia, that can also transfer noise when expanding/contracting

It is tough to say allthough tt can be normal assuming the gutters/fascia are metal and in an area of the home that receives direct sunlight (enough to cause expansion and contraction).  IMO

Brenda, This can depend on the building materials and the darker the color of the materials. In my experience this seems to be more common with darker colors as they tend to absorb more heat than the lighter ones. I've witnessed this happen with metal roofs, gutters and siding.

Just seeing this. But I agree with other comments. Gutter Topper is the only cover to use. It is the best and has a lifetime waratny. www. guttertopper.com check it out. You can check our site out with some exapmples also tho we are out of Utah. www.utahgutter.com

I am a 4th generation gutter guy and we have looked at all the covers and tested many of them. Gutter Topper by far is the best. I actualy pesonaly know Marshal roofing as wel Troy is as honest as they come. I would call them.
