Roof Recover and Overlay in Mesa, AZ
Roof recover and overlay in Mesa, AZ: we test the existing roof for wet insulation, remove what can't stay, and install a new membrane with drains and curbs adjusted for the added height.
The lifted edge of an old repair can matter to a recover long before the new membrane gets there. We check the existing surface, the layers under it and every detail the new roof will have to tie into. A roof recover or overlay in Mesa, AZ, starts with one decision: what can stay, and what prep does the new roof need on top of it? You should be able to follow that decision from what we found to the materials we're proposing, with any open questions marked where they apply.
We inspect the surfaces we can reach, review any roof records and explain the testing needed below. The proposal then lists the layers staying, the spot repairs and the new roof system. Keeping those separate lets you compare a recover fairly against a full replacement before materials are ordered or the schedule is set.
Can the old roof stay?
A membrane that looks intact on top is one finding, not a full picture of the roof underneath. We check old repairs, damaged areas and the deck where we can see it to decide which layers need testing. Core cuts answer specific questions about what's below, and each one is protected and sealed again. The report says what we actually checked and what's still hidden, so the recover decision isn't based on how the surface looks from a distance.
A roof inspection for a recover ties those findings to the areas that will be covered. We explain what needs to be confirmed for the new system and the deck under it, including whether code allows another layer on this roof, before the job moves forward. Keeping the old roof can cut out tear-off cost, but it adds its own prep and tie-in work. The estimate should show that work wherever the new roof depends on the old layers.
Finding and removing wet insulation
A soft spot or an area that looks different can mean water under the membrane. We mark it, compare it with what we can reach and test to find out how wet the layers are. The fix follows what we find. A new membrane doesn't make wet insulation okay to leave in place. Damaged material and the deck under it need a repair plan before anything goes over them.
An infrared moisture survey can map likely wet areas when conditions are right. Those readings are confirmed with cores before we decide how much to tear out. Where we find wet insulation, we mark the removal area and list the replacement materials that fit the new roof system. You'll see how that spot repair changes the recover price and what questions are still open, instead of treating a thermal image as the final word.
A recover review also has to account for water already held in the assembly. We compare visible drainage paths with the proposed new roof height and identify where a blocked drain or an uneven transition needs to be fixed first. Mesa's brief monsoon downpours can put a large volume of water on a low-slope roof in a short time, so drains and transitions belong in the decision. The proposal should say which fixes are included before the new roof covers them up.
Attaching the new roof
Before any new board or membrane goes down, we work out how it will attach to the old roof. We identify the existing surface, the prep it needs and the fastening or adhesive method, and check that the fasteners will reach solid deck. The manufacturer's requirements matter at every step. A recover proposal should name each material and where it goes, not assume another layer can go over anything that looks dry and flat.
A TPO roof recover usually includes a cover board or insulation layer, with seams and flashing done to the manufacturer's requirements. A PVC roof overlay needs its own choices about the surface it's going over and how it's attached. We explain the prep and materials your roof needs, including any review if a product substitution or new finding changes the plan. That lets you compare real work, instead of two bids for the same membrane that leave the work underneath undefined.
Drains and curbs after a recover
Adding layers raises the roof, which can change how water reaches the drains and cut into the flashing height at equipment curbs. We check those details while planning the recover, identify the drains and curbs that need work and plan the prep before the roofing starts. The new layers have to tie into flashing that fits the new roof. A curb or drain that worked with the old roof isn't automatically right for the new one.
The roof drain and scupper part of a recover separates drain changes from the membrane work around them. At curbs and pipes, we also check the backing and any equipment that has to be raised or moved first. Photos and measurements show you those changes before the new roof hides them. Careful detailing keeps the recover decision tied to every affected drain and curb, not just the open field where laying new membrane looks easy.
Scheduling a recover
Even with the old roof staying, each work area needs clear limits while the new roof goes on. We check conditions in each area, review the plan and protect any detail that isn't finished at the end of the day. Testing, spot repairs and equipment prep may need to come before the field membrane. The schedule should include all of that and the product's requirements, rather than assume keeping the old roof means no interruptions or exposure.
We match the building's rules to the recover schedule. Our occupied building reroofing approach spells out the protection and access limits that affect the roofing. That ties a real building to a workable schedule, while the actual operating rules come from your facility contact and the areas we inspect.
Recover vs. replacement
A recover price should include the testing and prep that make the old roof a sound base for the new one. We list spot tear-out, replacement insulation, attachment, curb and drain changes and flashing work. A replacement bid should describe its tear-off and deck work with the same detail. You can then compare what each proposal actually includes and see where hidden conditions or further review could change either price.
For downtown Mesa recover projects, the closeout record lists the materials left in place as well as the new roof installed. We photograph the prep and finished details, mark the repaired areas and separate anything still open from completed work. If someone investigates the roof later, they'll know which layers are under the membrane and where the recover changed a detail. The record keeps the material decisions behind the finished roof, which makes future maintenance and inspections easier.
Whether a recover makes sense near Downtown Mesa depends on the condition of the existing roof, how many layers are already there and the finished edge height. We identify what can stay and which details need to be torn out or opened. A building around Superstition Springs is assessed on its own before an overlay is considered.
QUESTIONS ABOUT Roof Recover and Overlay
What has to be confirmed before the old roof can stay under a recover?
That the existing layers are dry and solid, that the deck can hold the new fasteners and that the new system is approved over that surface. We test where needed before recommending a recover.
Can an infrared scan decide exactly what to tear out?
No. Infrared points to likely wet areas, but we confirm with core cuts before marking any insulation for removal.
Why might a recover need equipment work?
The new layers raise the roof surface, which can leave too little curb for proper flashing. We check each curb and note any raising or equipment work that has to happen first.
How will we know what's under the new roof later?
The closeout record includes material notes and prep photos. It shows which areas were repaired and which original layers stayed under the new roof.
