Roof ReplacementBased in Prosper, TX

The Difference

What to know before you decide.

A full replacement generally means taking the old roof off down to the wood. That exposes the decking, and decking is where a roof that has leaked for a while hides its damage: delaminated plywood, OSB that has gone soft around a chimney, nail holes that have rusted out. Anything that will not hold a nail gets replaced before the new system goes on. Building a new roof over bad decking is how a fresh roof starts leaking in its second year.

The new roof goes on in layers, and each one has a job. Metal drip edge protects the edge of the deck and directs water into the gutter. Synthetic underlayment covers the whole deck as a second line of defense. Leak barrier membrane goes into the valleys and around penetrations where water collects and runs. Then come the starter course, the field shingles, the ridge cap, and new flashing and pipe boots. Reusing old flashing to save an hour is a common shortcut, and it is the usual reason a new roof leaks at the same chimney the old one did.

We are a CertainTeed ShingleMaster contractor with CertainTeed Master Craftsman credentials. Manufacturers use programs like these to train and vet the contractors who install their systems, and they generally tie their stronger system warranties to a full, matched installation by a credentialed contractor. When we price the job we will explain which warranty options apply to your roof and what each one covers.

The shingle itself is worth a conversation in this part of Texas. Architectural shingles are the standard now. The upgrade to consider is an impact-resistant shingle rated Class 4 under the UL 2218 test, which is built to take hail better, and many Texas insurers offer a premium discount on a Class 4 roof. The discount varies by carrier, so it is worth a call to your agent before you choose.

Cost depends on the size and pitch of the roof, how many layers are coming off, how much decking needs replacing and which shingle you pick. As a market range in North Texas, an architectural shingle replacement on a typical single-family home commonly lands somewhere between $10,000 and $22,000, with steep, cut-up and two-story roofs toward the top of that range. When hail or wind caused the damage, most of that is usually paid through your homeowners policy less your deductible. Financing is available when it is not.

Most replacements are one or two working days once the weather is dry. Move cars out of the driveway and garage the night before, keep pets indoors, and expect the old roof coming off to be loud. Collin County towns generally require a permit for a reroof, and many neighborhoods in Prosper and Celina also want HOA approval of the shingle color before work starts, so bring that up at the inspection and it can be sorted before a date is set.
