The Allegiance Difference
Why Katy Homeowners Call Allegiance for Patio Extensions
One crew for your whole exterior
We already handle roofing, siding, and gutters. Adding a covered patio means the structure ties into your existing exterior the way it should, not as an afterthought.
A clear written quote before we start
You will know exactly what you are getting and what it costs before anything gets ordered. No surprises once work is underway.
Built for the Texas climate
We know what holds up in Katy heat, humidity, and storm seasons. Materials and construction methods are chosen with that in mind from the start.
20 years of local work
We have been working on Katy homes for over two decades. We understand the neighborhoods, the codes, and what homeowners here actually want from their outdoor space.
What We Build
Why Katy Homeowners Add a Covered Patio
Reason 1
Shade that makes the backyard usable again
Katy summers push people indoors. A covered patio brings the yard back into the picture for most of the year.
Reason 2
Protection from sudden rain
An afternoon shower does not have to end an evening outside when you have a roof overhead.
Reason 3
Extends your living space
A covered patio that opens from the house adds functional space you can actually use for entertaining, dining, or relaxing.
Reason 4
Adds lasting value to the home
A well-built covered outdoor space is a feature buyers notice and one sellers can point to with confidence.
The right covered patio does more than add shade. It changes how you use your property for years to come.
Our Services
Patio Extension Options That Fit Your Home
Built around how you live
Whether you want room to entertain, a shaded spot to unwind, or cover over an existing slab, we start with how you will use it.
Matched to your home
We design the extension to match your roofline, materials, and exterior, so it reads as original to the house instead of bolted on later.
Sized and placed for your yard
We study your slab, drainage, and lot before recommending a size and placement that works with the space you have and how it sits.
Shade and coverage your way
From partial shade to full cover, we walk you through how much sun, rain, and openness you want, then design and build exactly to that.
A well-planned gutter installation should disappear into the house and just work.

Common Questions
Patio Extension FAQs in Katy
In most cases, yes. Covered structures attached to the home typically require a permit in Katy and the surrounding area. We handle that process as part of the project so you are not navigating it on your own.
It depends on the size and complexity of the structure. Most projects are completed within a few days once materials are on site. We give you a realistic timeline in the written scope before anything starts.
Often yes. We assess the existing slab as part of the consultation to make sure it can support the new structure properly. If additional concrete work is needed, we will let you know upfront.
We walk you through the options during the consultation and make recommendations based on what performs well in this climate. What holds up here is not always what looks best in a catalog, and we will be straight with you about the difference.
It depends on the size, materials, and complexity of the structure. We give you a written number after we have seen the space in person, not a guess over the phone.
