Q: What is your relationship with Luthy Metal Sales?

In the past, we were the installation crew for Luthy Metal Sales. With increased sales and a desire to focus more on manufacturing they proposed that we take over the installation completely. Integral Builders is now completely independent of them, yet we still work closely together, purchasing all our metal roofing products from them.

Q: Do you use nails or screws to fasten the metal?

Because of it’s superior ability to remain secure, we use screws instead of nails.

Q: Where do you put the fasteners, on the rib or on the flat?

The fasteners always go on the flat area so that the rib can move to allow for expansion and contraction.

Q: What seals the fastener holes?

We use a metal screw that has a rubber seal which seals against the metal. To prevent the rubber seal from deteriorating from the sun's UV rays a metal washer is used to cover it.

Q: How do you seal around pipes protruding through the roof?

We use a rubber roofing boot that has a twenty-year warranty.

Q: How do you seal around a chimney?

On a brick, block or other masonry chimney we actually cut into the masonry leaving a small crack where we can put our custom bent trim into the crack so it naturally seals tightly. On Steel walled chimney pipes we use our roofing boot.

Q: What happens at the edges of the roof?

On the rake side ( the sides on an angle) we use a corner trim that overlaps the metal on the top and comes down about two inches covering some of the existing fascia. At the eave edge, we use a “C” trim which on the top side it goes under the metal roof, on the front, it covers the existing drip edge, and on the bottom, it returns in against the fascia.
