I was very happy with service that was offered before during and after the installation. I will definitely recommend their services to others who need a roof.

Slate roof repair on older Houston houses
Slate can outlast the house. The nails, the copper valleys, and the flashing usually give up first. Treating it like a shingle roof is how the street face gets chewed up.
A broken slate comes out. A new one goes in with a copper hook or a nailed strip hidden by the course above, so the face is not pierced. Copper nails are the fastener. Steel nails rust, swell, and pop the piece. We carry the traffic on ladders and hooks, and we replace what we break.
The leak is often the valley or the dormer, not the slate you can see from the curb. Copper valleys crack at the fold after decades of heat. Chimney flashing pulls out of the mortar. Those are repairs. A field that is delaminating or shedding in sheets is a different conversation.
New slate is a structural question before it is a style question. If the frame was sized for the original and the original is staying, repairs keep the look. If the frame is tired, stone-coated steel can keep a textured profile without asking the rafters to hold quarried stone again.
This is a small part of our work on purpose. Older Houston houses and custom homes in The Woodlands and similar pockets are where real slate shows up. We will not talk you into tearing off slate that still has decades in it.
Free slate roof inspection
Tell us the address. We call the same day. Slate gets ladders and hooks, not a walk across the field.
A hook, not a nail through the face
The repair is hidden by the course above. A face nail is a new leak and a broken piece you can see from the street.
Copper at the valleys and the chimney
Those details fail while the field still looks intact. We open the detail, not the whole slope.
Weight decides a replacement
Another slate roof has to fit the frame. If it does not, we say so before anyone prices a quarry order.
From the crew
Questions before we get on the roof
The shop is in Tomball. The work is the Houston suburbs where these roofs actually are.
Can one broken slate be repaired?
Yes. We pull the broken piece and set a new one with a copper hook or a hidden nail, then replace anything the access broke.
Do you walk a slate roof to inspect it?
Not like asphalt. Ladders and hooks. A crew in ordinary boots across the field will break pieces you cannot hide.
When is slate actually done?
When the pieces are delaminating or shedding across the field, not when one valley copper has cracked. A cracked valley is a repair.
What goes on if the house cannot carry new slate?
Stone-coated steel can keep a textured profile at a fraction of the weight. We only go there when the frame is the limit.

I reached out to Montgomery with Core Four Roofing on Friday, July 14th, requesting a quote. I received the quote the same day. The quote was thorough, easy to read, and by far the best price. I asked how soon they could complete the job and Montgomery got back with me immediately stating they could do it the following Friday or Saturday. I requested they come Friday. Workers arrived and completed the job that Friday. The roof looks amazing and the job site was left with no evidence, short of the gorgeous new roof, that they had been there. Several of my neighbors have spoken with me stating how great the roof looks. Core Four Roofing and Montgomery get a 5 star A+++ from me. I would highly recommend them for any of your roofing needs.

Cody was quick to meet the adjuster was helpful through the process. Not a flyby night company, very professional and knowledgeable.
