New construction
Additions, decks and outbuildings for the house you already have
Additions and new rooms, decks and patios, enclosures and sheds. Built to tie into the house that's already standing, not fight it.
Chapter 01
An addition ties into the roof you already have, or it doesn't tie in at all
The framing on a room addition is rarely the hard part. The hard part is where the new roofline meets the old one, because that seam creates a valley, and a valley cut wrong is the single most common way a brand-new addition starts leaking a few winters after the crew that built it has moved on to the next job.
We tie the new deck and shingle plane into the existing roof so water has one path down instead of a seam it has to argue with, and we don't invent a valley just because it was the easiest way to frame the addition. If the roofline doesn't want to meet cleanly, we change the plan before we change the flashing.

Decks, patios and pergolas built for Texas sun and Texas ground
A deck in North Texas takes two things most builders design for somewhere else: sustained summer heat that dries and moves wood faster than a mild climate ever would, and blackland clay underneath that swells and shrinks with every wet-to-dry cycle. Footings set shallow, or sized for a milder climate, are why a patio slab cracks at the seam in year three instead of year twenty.
We foot decks, patios and pergolas below the active zone of that clay, and we choose fasteners and board spacing for a structure that will sit in full sun for a decade, not a showroom photo. The pergola and covered patio work in our own job photos, bar rail and fire table included, was built to that same standard.
Chapter 03
Enclosures and sheds start with the ground, not the walls
A shed or an enclosure looks like the simplest thing on this list and is the one most likely to get built wrong, because the foundation and drainage underneath it get skipped in favor of framing everyone can see. Water that isn't graded away from a slab will find the lowest point, and on a small structure that's usually straight under the door.
We foundation and drain enclosures and sheds properly, and we pull the permits the job actually needs before we start, the same as we would on a house. MAG Builders is licensed, bonded and insured, a member of the North Texas Roofing Contractors Association, listed on Porch and HomeAdvisor, and featured on Angie's List, and those credentials back a shed just as much as they back a roof.
MAG Builders offers free inspections on every project, and our technicians can assist with the insurance-claims side of a job when storm damage is part of what started the conversation. Call 817-823-7224.
