Question 1

What types of roofs can I use Grip Clip 625 on?

Accepted Answer

Grip Clip 625 is designed for thicker roofing materials with a thickness between 3/8" and 5/8". That includes cedar shingles, tapersawn cedar shakes and popular synthetic slates like DaVinci. For thinner asphalt shingles, use Grip Clip 325. For really thick roofing up to 7/8", use Grip Clip 875.

Question 2

How many Grip Clips do I need for a typical roof and gutter heat cable project?

Accepted Answer

Plan for one clip at each bottom “V” in your zig-zag pattern and additional clips every 2 feet along the top and bottom of your zig-zag runs. Our Heat Tape Calculator provides a good estimate for your layout. For valleys, figure about 6 Grip Clips to run cable up and down each valley, spaced roughly 30–36" apart.

Question 3

How do Grip Clips attach without nails or screws?

Accepted Answer

Grip Clip 625 is designed with a body that acts as a toothy pincher. Two opposing arms of corrosion-resistant anodized aluminum grip tightly when slid into place. The barbs bite into the roofing surface securely without causing any damage.

Question 4

Will Grip Clips damage my roof or void the warranty?

Accepted Answer

No. While nail-on clips puncture shingles (because they’re nailed, duh) Grip Clips lock onto the shingle roofing with no penetrations, protecting both the roof and the warranty.

Question 5

Do I need tools to install Grip Clips?

Accepted Answer

Not for Grip Clips 625 of 875 because they’re designed for thicker roofing materials and those materials don't have glue strips. To remove Grip Clips all you do is lift the arms and wiggle the clip out.

Question 6

Can I reuse Grip Clips if I move my system?

Accepted Answer

Not recommended. Once removed, the aluminum usually loses its ability to firmly bite into the shingle. For best performance, use new clips.

Question 7

What size shingles does Grip Clip 625 fit?

Accepted Answer

The “625” refers to the clip’s mouth height. Grip Clip 625 fits shingles between 3/8" and 5/8" thick. For thinner roofing, use 325 and for roofing up to 7/8" thick use 875.

Question 8

What are Grip Clips made from?

Accepted Answer

Grip Clips are made from 5052 aluminum alloy, selected for its spring strength, corrosion resistance and ability to handle extreme freeze–thaw conditions.

Question 9

Can I use Grip Clips in gutters or downspouts?

Accepted Answer

No. Grip Clips are designed for roofing applications only.

Question 10

What’s the advantage of Grip Clips over standard nail-on clips?

Accepted Answer

They eliminate penetrations. Each clip holds cable firmly (minimum of 25 pounds of pull force) without creating holes that can void warranties. Install speed is also faster since no drilling or nailing is required.

Question 11

Can Grip Clips be used in roof valleys?

Accepted Answer

Yes. Grip Clips allow you to place heat cable closer to the centerline of the valley, where ice dams typically form. This improves melt-path performance without nails or adhesives.

Question 12

How long will Grip Clips last?

Accepted Answer

Many years. The aluminum alloy resists corrosion and weathering, ensuring long-term reliability.

Question 13

How quickly can I get my Grip Clips for my ice dam prevention project?

Accepted Answer

We keep them in stock and ship same day from Minnesota, don’t ‘cha know (assuming you don’t order too late in the day!). Orders placed over the weekend will ship the next business day.
