Built-Up Roofing (BUR) in Mesa, AZ
Built-up roof repair, recover and replacement in Mesa, AZ. We cut and read the plies, check flashing and drains, and price each option from what the roof actually has.
On an old built-up roof, the gravel around a pipe boot can look fine while the asphalt underneath has cracked through. That is why our BUR inspections in Mesa start at the leak or the worn area and then follow it to the nearest wall, drain or penetration. Mesa's long hot season bakes exposed asphalt and flashing, and winter rain and the July-to-August monsoon storms are when bad drainage shows up. Before you compare a patch, a recover and a full tear-off, you need to know which parts of the roof are still sound. We photograph what we open, note where it is on the roof, and tell you plainly if one more core cut would change how much material has to come off. A recover price spells out what the existing roof has to support and how the new edges and flashings tie in. A replacement price covers tear-off and what happens if the deck needs work once it is exposed. The decision comes from the layers on your roof, not from its age or how it looks from the hatch.
The surface has limits
A built-up roof is layers of felt and asphalt with a cap sheet or gravel on top. A crack in the cap may stop there, or it may run down into the plies below, and the inspection has to find out which. Our hands-on BUR inspection looks at the exposed layers at the split, photographs the area and tells you whether a small opening is needed to decide how much of the surrounding roof can stay.
Mesa's summer sun is hard on asphalt and exposed flashing. After months of dry weather, one short heavy rain can overload a drain and leave water standing in low spots. We look at the damaged area and at the path water takes to the nearest outlet. That gives the facility director a real basis for comparing a spot repair with a recover or a replacement, rather than a guess made from the hatch.
Gravel can hide damage to the plies beneath it. We clear only the area we need to see, check how deep the problem goes, and note whether it reaches the felts or stays at the surface. That answer drives how much material comes out and how the new plies tie into the old ones. Aged BUR gets brittle in Mesa's hot, dry months, so we cut carefully and close every opening the same day with proper roofing, not a rough patch left for later.
Core cuts with a reason
A core cut should answer a specific question, and we agree on where it goes and how it gets sealed before anyone cuts the roof. We note the layers we find, take photos and mark the spot on a roof plan so later decisions can be traced back to it. One core tells you about that one location. If the roof changes from one section to another, we may need a second or third cut before we can say what is underneath.
An infrared moisture survey can help find wet insulation under a BUR roof when the weather and roof conditions suit the method. Hot spots on the scan still need to be confirmed with cores before we draw a tear-out line. Wet insulation gets priced as part of the repair, along with the deck under it and the plies around it. That way the facility director gets a removal area based on evidence, not a broad guess drawn from a thermal image.
Wall and edge flashing
Many BUR leaks start where the roof meets a parapet wall, a curb or an edge. To fix that junction properly, we need to know what the old roofing is and what the new flashing will be made of. We check how the existing flashing is fastened, what the wall behind it looks like and what earlier patches are in the way. If the wood nailer or wall backing is rotten, it has to be replaced before new flashing goes on, and the estimate says so instead of burying it in a line item called "repair flashing."
Sometimes the best fix at a wall or edge is a modified-bitumen flashing bonded to the old BUR. Where a building owner is moving part of the roof to a TPO membrane, the change-over between the two systems needs its own detail, because TPO does not bond directly to asphalt. We show you exactly where the two systems meet, how that seam will be built and what the crew has to prep first.
Choosing the install method
Hot asphalt, cold-applied adhesive and torch-applied cap sheet each come with their own rules for temperature, handling and safety. We pick the method that suits the roof and the building, then plan the work around it. On an occupied building, that can mean scheduling around rooftop air intakes, protecting the area below and agreeing on fire watch if a torch is used. Those details get settled with the building owner and any other trades before roofing starts.
On a multi-day job, the facility director should also know what is left open overnight. We mark the day's stopping point, seal it with a temporary tie-in and tell you what is still to come. Access, material storage and staging all go into that plan. The goal is simple: nobody installs new roofing over a flashing that still needs fixing, a core that still needs reading, or a curb that another trade has not finished.
Recover versus replacement
A recover only makes sense if the existing BUR can stay in place. We check which layers would remain, whether the insulation is dry and whether the roof can take the added weight. A BUR recover also changes the flashings, edges and drains, so those changes are in the price. Looking at the top surface alone does not tell you whether the roof underneath is good enough to keep.
A full replacement is priced separately: tear-off, disposal, deck repairs found once the roof is open, and the new system. If you are also considering a coating, we check whether the existing surface is clean and sound enough to take one before recommending it. You end up with options you can compare side by side, each showing what it includes and what is still unknown. That keeps the choice tied to the actual roof, not to a favorite product.
Keeping a record of the roof
A built-up roof should be judged by its layers, surfacing, drainage and flashings, not by its age or how it looks. Our review covers what we can see and reach, and tells you where a core cut or old drawings would fill in what we cannot. A repair proposal states which layers and flashings it fixes and how the new work ties into the old roof. A replacement proposal states what is coming off and what we expect to find underneath. Keeping a record of the layers found and the areas repaired helps you make the next decision from facts instead of a generic label.
For built-up roofs around Downtown Mesa, the estimate lists the surfacing, the visible layers and where new material meets the old. A building near the Mesa Gateway Area gets its own inspection and its own tear-off limits, based on what is on that roof.
QUESTIONS ABOUT Built-Up Roofing (BUR)
Does surface cracking show how deep the repair needs to go?
Not by itself. A crack in the cap sheet may stop at the surface or run into the felts below. We check the affected layers, and if the answer is not clear from the surface, we make a small core cut before setting the repair area.
Why look at old repairs before adding another layer?
Old patches, mastic and coatings can keep new material from bonding. We find those spots, remove or prep them as needed, and pick flashing and repair materials that will actually stick to what is there.
Can a BUR roof be recovered with a different membrane?
Often yes, but the existing roof has to be dry and sound, the structure has to carry the weight, and the edges and flashings have to be rebuilt to suit the new membrane. We check all of that before including a membrane change in a recover price.
How do I compare a BUR repair proposal with a replacement?
Look for clearly marked work areas and a list of what each option includes: spot repairs, layers that stay, tear-off, flashing and nailer work, and anything still unknown. We lay our proposals out that way so the options line up side by side.
